Life cycle cost is a key economic figure resulted from condensing an almost overwhelmingly large quantity of data (Pelzeter et al, 2007). The accuracy and sensitivity of these data can be difficult to analyze to become reasonable inputs for life cycle costs assessment.
For hydropower projects, there is a master plan to develop these projects in almost every country. However, because of the available budgets, the projects are needed to be ranked in order to decide which projects are necessary, economical and beneficial more than others. Life cycle cost analysis is one of the useful ways in decision making process and long term planning of the project. So, different projects are needed to compare their life cycle costs and incomes. Because of the various factors that can affect on hydropower projects, the uncertainty and the risks are high and difficult to predict.
Mr. Kyaw Min Thu made a case study which major objectives were to: (1) compare the life cycle costs and net present values of hydropower projects/plants with different types of turbine; and (2) identify the major cost contributors in life cycle cost of each project,
Conclusions
In this research, life cycle cost analysis of hydropower projects installed different types of turbine are conducted on the costs incurred in the hydropower plants to determine the most beneficial technology in terms of cost effectiveness. The hydropower plants for this research are selected among the hydropower plants in Thailand which are operating under management of EGAT. To conduct the analysis, all accessible cost data are collected and the researcher followed the cost categories of responsible agencies. All the costs incurred in the selected hydropower plants that can be accessed are considered and then converted into the same period to analyze. The costs data are converted in the same unit (thousand baht per year) at the end of each year within the analysis period.
Moreover, the energy generated data from each selected hydropower plant are collected and calculated the incomes of the power plants each year using the average energy sales price. The incomes getting from the energy generation are considered and calculated as one of the parameters in life cycle cost analysis for wider perspective to determine the outputs. The net present values of the hydropower plants are achieved from the costs and incomes incurred each operation year in the hydropower plants. The analysis’s results are converted into cost per capacity and cost per energy as the capacity of the hydropower plants can affect the results of the analysis.
Among factors influencing the selection of the turbine types of hydropower plants, the result of life cycle cost analysis can be just one of those factors. A final decision may include a number of additional factors outside the LCCA process, such as availability of funding, capability to perform the required construction, expertise and experiences with a particular turbine type and so on.
1. Comparison of Life Cycle Costs of Hydropower Plants
As the capacities of the hydropower plants that can get enough data to conduct analysis are different, the analysis is performed to get the values for unit capacity and unit energy generated for each hydropower plants.
Based on the data analysis for three types of hydropower plants with three different types of turbine, the Francis turbine power plant is more cost-effective than other two types of power plants with respect to the life cycle cost per installed capacity, life cycle cost per energy, net present value per installed capacity and net present value per energy.
The Kaplan turbine hydropower plant and Pelton turbine hydropower stand as decreasing order with respect to their life cycle costs per installed capacity, life cycle costs per energy generated and net present values per capacity and energy generated by the Pelton turbine plant has the larger values than that of Kaplan turbine plant. Thus, the Pelton turbine hydropower plant is more favorable than that of Kaplan plant in terms of cost-effectiveness.
2. Major Cost Contributors in Hydropower Plants
The present values of each cost categories involved in total costs of hydropower plants for each year are calculated to find out the contributors and their ratios in the life cycle costs. The researcher follows the responsible agencies in categorization the costs incurred in the hydropower plants.
In every plant, the life cycle costs spent for civil structures are the largest in the life cycle costs for the whole plants, in other words, life cycle costs of civil structures are major cost contributors in whole life cycle costs of hydropower plants. However, taking account only the operation and maintenance costs, the costs incurred for the electromechanical equipment are the larger than for the civil structures.
In terms of costs per capacity and energy generated, for each cost category, the hydropower plants can be arranged as Kaplan, Pelton and Francis turbine hydropower plant in decreasing order.
According to the results of the analysis, Francis turbine power plant has the least cost per energy generated in all cost categories so Francis turbine is the most favorable among hydropower plants with different types of turbine.
Thus, life cycle costs of civil structures in the analysis period are the major costs contributors in all types of plants while the operation and maintenance costs of the electromechanical equipment are major cost contributors among the total operation and maintenance costs of hydropower plants

Abstract
The hydropower projects are needed relatively large amount of investment relative to most of the other projects in construction industry. Thus, the decision making on selecting the technologies using in the hydropower plants are needed to analyzed well because of the costs incurred in the whole life of the plant come from the decisions made before starting construction and operation of the plant. Life cycle cost analysis is worth to be conducted as it can give the results not only on the initial costs but also on the costs in the whole life of the studied assets.
In this study, the objective is set to conduct the life cycle cost analysis for the hydropower plants which are installed different types of turbines. The life cycle cost analysis for each type of plant is carried out and the results are shown as per capacity and per energy generated of the plant. The main components of the inputs, which are historical data from hydropower plants, are gathered from the representative agencies. The comparisons of the results of the analysis are performed to select the most cost-effective technology for the hydropower plants in long term basis.
As the results of the analysis, it is found that Francis turbine hydropower plant is more cost effective over than other types.

Factors Affecting Operation and Maintenance Costs of Ho Chi Minh City Condominium Projects
The management of condominium project during the operation stage is an emerging problem for project owners. Normally, the owners focus on development stage and construction stage of the project. They mainly concern in problems related to planning, design, and execution (Arditi & Nawakorawit, 1999a).
In order to recommend to owners or property managers appropriate solutions to control and reduce O&M expense. Mr. Duong Quang Minh made a study which, first, will develop operation and maintenance cost system of existing condominium projects. The purpose is to identify the most important costs in this system. Second, the study will investigate the reasons that cause the cost. Thus, the three main objectives of his study were to: (1) build a generic framework for operation and maintenance cost system of existing condominium projects; (2) find out and assess factors affecting on operation and maintenance cost of existing condominium projects; and (3) recommend solutions to reduce or control the impact of the factors that influence on O&M costs.
Conclusions
For Objective 1
The study analyzed cost data from five case studies to identify the most important cost of operating condominiums. Each cost was given a brief definition, its components, and characteristic. Then, the study developed the generic framework of operation and maintenance cost of condominium projects. The framework is benchmark to compare O&M costs between condominiums.
From the benchmarking, the study found that cost for condominium management is the highest cost with about 46.42 percent of total O&M cost. In addition, energies supplying for common activities of condominium are also high with about 18.26 percent of electricity consumption and about 9.23 percent for water consumption. Also, costs of cleaning and waste disposal are high by about 9.61 percent and costs for maintaining lifts are 6.01 percent.
The reasons behind this high cost include:
1. Management cost: The reason may be inappropriate choices between in-house or out-source employment.
2. Energy consumption cost (Electricity and water supply): There are three main reasons that cause high expense for this cost center such as general facility influences, installation of an old-fashion technology in the facilities, and maintenance policy including lack of daily inspection and preventive maintenance.
3. Maintaining lift cost: Maintenance costs of lifts are costs connected to planned maintenance works to the lifts in the common areas of condominium.
4. Cleaning and waste disposal cost: Reasons that may cause cleaning service cost is lack of design specification of cleaning tasks and inappropriate choice of construction material, specially decorated material.
Objective 2
There is no significant difference between in-house and out-sourcing employment condominium managers. In general, both managers pay attention into reducing operation and maintenance costs. However, based on characteristic of each employment type, the condominium managers have different maintenance strategy to perform the maintenance task effectively. Therefore, they have different perception about the factors that influence to O&N costs.
Recommended solutions to reduce or control the impact of the factors that influence on O&M costs
For new condominium projects, property manager is usually the one that handles all the defects or design faults after the completion of construction stage. Base on accumulated experiences in handling the defects from different building projects, the property manager can feed back what they have suffered from the experiences to the project team. Besides, as the property manager's role is to manage the property, they usually meet the tenants that propose many expectations or requirements to make better living condition of condominiums. These expectations may be valuable information for the owner to make the right decision when investing in new condominium project. In order to better manage the project, property manager should:
• Select appropriate in-house or out-sourcing staff to perform maintenance tasks efficiently
• Imply conservation energy program in order to control and reduce energy consumption
• Pay attention in the management of maintenance task for lift system
• Pay attention in the management of cleaning tasks
The recommendations for the first finding are shown in the below.
There are two recommendations for condominium managers. One is for in-house employment condominium and another for out-sourcing condominium.
For in-house employment condominium, if the condominium owners decide to employ in-house staff to perform the maintenance task, they should invite maintenance specialists to give their advisories during the design stage in order to reduce the maintenance costs as well as operation costs. On the other hand, if there is no participation of maintenance experts in the design process and there are many problems occurring during the operation stage, the project owners should use external staff to perform the maintenance work.
For out-sourcing employment condominium, there is a strong wish of out-sourcing condominium manager about the provision of construction material information. In order to perform maintenance tasks efficiently, the project owner should ask the designer that provides the specification about the characteristic of construction material using for the project. Especially in the case that project owner decides to use out-sourcing staffs.

Abstract
High-rise residential property management sector in Vietnam is still staying at the early stage of development. There is lack of maintenance concept of building development because most of project owners are only attracted in completion project. Condominium managers have not appropriate maintenance policy for the completed building, and it deteriorates faster than expected service year. Maintenance issues become emerging problems that should be concerned. This study aims to investigate practical management of condominium projects in Ho Chi Minh City through management of operation and maintenance expenditures.
Around the areas of HCMC, the researcher visited many exiting condominiums that have been operating since year 2000. In achieving these objectives, opinions of in-house employment condominium managers and out-sourcing employment condominium managers were sampled through structured questionnaires. The data collected were analyzed using descriptive and inferential statistics. There is a difference between condominium manager’s perception about two sub-factors affecting on operation and maintenance cost. They are “Lacking of involvement of maintenance experts during design stage” and “Materials selection does not comply with the client's activities due to inadequate accurate material information source”
On the other hand, real cost data were also collected from five condominium projects. The purpose the study was that identified the most important O&M costs of condominium by comparing costs among condominiums. Benchmarking was established to compare cost each other. The result of comparison was that found out six most important cost including management cost, electricity consumption, water consumption, cleaning and waste disposal, and lift maintenance cost. After all, the study proposed many solutions that not only help condominium managers managing their assets better but also help other participants concerning about maintenance issues for developing new projects.

Factors Affecting Constructability Practices in Hydropower Construction in Nepal
Nowadays, the construction industry lacks constructability, which causes many problems, such as increased cost and time required for constructing a project, reduced productivity of project personnel and equipment, and low-quality construction (Nima et al., 2002). In this connection, it is worthwhile to investigate the drawbacks of the existing practices and application of constructability concepts.
Systematic application of constructability concepts will enhance constructability of a project. Consequently, schedule, quality and cost are optimized and all the parties are benefitted from the project. Nepal is practicing constructability concepts in hydropower development however these concepts are not recognized with importance by the key practitioners. Mr. Mukesh Khadka made a case study which objectives were broadly divided into following three parts:
i. To find out constructability concepts and implementation barriers applicable for different phases of hydropower project namely conceptual planning, design and procurement, and construction/field operation.
ii. To identify the degree of importance, level of application and major implementation barriers of constructability concepts in hydropower construction in Nepal.
iii. To propose recommendations for the effective application of constructability concepts in the hydropower project construction in Nepal.
Conclusions
1. Identification of constructability concepts and implementation barriers
For Nepal, thirty-six constructability concepts suitable for hydropower projects are identified out of which seven concepts are suitable for implementation during conceptual and planning phase, twenty-one concepts for design and procurement phase, and last eight concepts are suitable during construction or field operation phase. In hydropower industry, 49 implementation barriers were obtained from expert review and play key role to deter the implementation of constructability concept.
2. Identification of degree of importance, level of application and major implementation barriers
The result of this study confirmed that six concepts are very important constructability concepts in overall respondents’ opinions. The very important constructability concepts are (1) provide detail and clear design information, (2) investigate the impacts of design on safety during construction, (3) documentation of works of good contractors based on quality and time, (4) carry out thorough investigation of the site, (5) evaluation, documentation and feedback of the issues of the constructability concept, and (6) technical specification. Remaining thirty constructability concepts is accepted as important constructability concepts for hydropower construction in Nepal.
The research has also revealed that none of the concepts are being highly applied in hydropower construction in Nepal. All constructability concepts are believed as concept with medium application except three concepts namely, (1) innovation on temporary construction materials/systems, (2) employ any visualization tools such as 3D CAD to avoid physical interference, and (3) design to avoid return visit by trade which fall into category of concepts with little application.
During the study, major constructability implementation barriers were identified and ranked as top ten implementation barriers. These barriers were further grouped into three dimensions named as (1) Ineffective communication and coordination, (2) Socio-political influences, and (3) Insufficient resources using factor analysis. Ineffective communication and coordination between parties may cause conflicts that could eventually impact the project constructability adversely leading to dissatisfaction of the project parties, reworks, variation orders and claims. Not following the execution plan of the project may hamper the critical path of the project thereby causing the time and cost overrun of the project. Socio-political influences are the major barriers of hampering implementation of constructability concepts. Disruption by local people and road strikes imposing various reasonable and sometimes unreasonable causes seriously hamper the project constructability. Insufficient resources due to limited project budget also hinder the implementation of constructability concept. Due to lack of incentives given to the employees, it is very difficult to implement the constructability improvement concepts as employees are the key player for applying them.
Recommendations
Further study is recommended for the following subjects:
• Further study considering large number of hydropower projects of various sizes, different financing models and identification of specific barriers for each constructability concept is necessary in milieu of developing guidelines for hydropower projects
• Further study can be extended to find the detail procedures for effective application of those constructability concepts in hydropower construction and to find the most suitable contracting approach which facilitates effective constructability application.
• A study on suitability of constructability issues in various kinds of contracting approach can be done.

Abstract
Nepal has favorable condition to develop numerous hydropower plants yet it is facing eighteen hour load shedding per day during dry season. Traditional approach adopted in Nepal for hydropower construction involves many problems such as design changes, reworks, poor safety practices, time delays, cost overruns, disputes, claims which hampers constructability of the project. In this context, it is worthwhile to conduct research which focuses on investigation of the degree of importance and level of application of constructability concepts and identifying the major barriers hindering effective implementation of those concepts. The findings would be appropriate for the preparation of baseline required in constructability improvement guideline for hydropower construction in Nepal.
Thirty-six constructability concepts and forty-nine implementation barriers related to hydropower construction in Nepal were selected for detail study after extensive literature review and expert verification. Through questionnaire survey, opinions on those constructability concepts and implementation barriers were collected from fifty-three managers/engineers associated with hydropower developers, consulting firms and construction companies involved in hydropower construction in Nepal. The quantitative data gathered were then analyzed using various statistical techniques to conclude and recommend further studies. The result of this study revealed that six constructability concepts were accepted as very important concepts by overall respondents and the remaining concepts were considered to be important. To the contrary, none of the concepts are being highly applied in hydropower construction in Nepal. Further, ten major constructability implementation barriers were identified and grouped as ineffective communication and coordination, socio-political influences, and insufficient resources using factor analysis.
The effective implementation of constructability concepts in hydropower projects in Nepal can be attained by developing guidelines for the application of those concepts. For preparation of the guidelines the concepts identified by the study need to be verified with hydropower projects of various sizes and different financing models and detail procedures for applying those concepts should be documented. Also, identification of specific barriers for each constructability concept is necessary in milieu of developing guidelines for hydropower projects.

Effective Pricing Negotiation Strategy of Variation Claims in Commercial Building Construction
The valuation of variations is near daily task on large construction contracts. It is a norm in the construction industry where one of the contracting parties disagrees about the valuation of work done. Thus, the valuation of variation orders has been admitted as one of the main causes for conflict and disputes in construction management. A mechanism is required to accommodate the process of the changes in order to derive a more objective decision-making. An appropriate mechanism should be identified as a potential feasible solution for modeling the decision making process in the valuation of variation.
As abovementioned, Ms. Supatchana Pumpipat conducted a research studies for proper quantification of variation claims by emphasizing the varied works impact to cost structure which will be claimed by the contractors. Therefore, the major objectives for her study were to: (1) classify the variation works types in civil works of commercial building project and identify the problems that incurred in managing variation; (2) find out how to price the varied works that is generated from variation order that could be caused of claims and disputes; and (3) propose proper valuation process and the effective negotiation on the accepted price for both contractor and owner.
Conclusion
Based on the Case Study, the rebuilding shopping mall project garnered variation orders that were classified into five (5) categories such as:
i) New work – are the additional item in the some part of building for more suitable and aesthetic of the building. Frequently, this category is initiated by owner
ii) Modified work – are the existing of buildings becomes unsuitable for their present use, and then improvement, repair and maintenance are often required to keep them in usable condition.
Change work – are covered amend in some parts or whole scope of work that is stipulate in the contract
iii) Move work – are Moving things without creating any damage to those items including storage of those items, they assume a duty to be included in this section.
iv) Demolishing work – are move the existing part out and would not be reused. And the occupancy of debris that comes from the demolishing process will be agreed before starting work.
v) Correcting Work – items that are corrected or fix the damage of building. Most of them are architectural work.
At first, the author would like to identify the specific valuation method in each variation categories but based on interview, the valuation methods is not related to the variation categories. The valuation methods depend upon the condition and the character of the varied work.
The formulation procedure was initiated in order to manage the emerging variation orders. Basic flows of steps were provided but still flaws were found in processing time in every step. Some VO can be process without any difficulty and some may takes time to verify the submission documents, verify evidence, to gather data to confirm entitlement of the contractor to claim VO. Resolutions to variation order impact through variation order management were viewed and as to the effectiveness of current procedure. Current procedure is useful but can be developed to improve processing period and administer each changes lessening the probable effect to the whole project particularly on the cost.
Actually, the problems of this project are generated in every stage of variation procedure which will only base on the contractor’s viewpoint such as follows.
1. Notification - Information of change is given by either the PM or Contractors or whoever identifies the variation and all site instructions that may constitute a variation should readily indicate and require the Contractor to submit quotation. In the event that the Contractor submits a proposal like for example value engineering, this is the only time when the Project Management team conducts a preliminary analysis on time, cost, quality and the overall effects of the change in the construction.
2. Evaluation – the stage of gathering data to confirm support documents submitted by the Contractor. Determine the quantities, cost and time involved in the variation request. Coordinate the change with the trade in the construction for probable effect on the progress of the work and the work itself. At the same time coordinate with the contractor’s QS for comparison, checking and correcting evaluation. This will greatly discourage dispute in final cost later and save time on repeated evaluation in cases of disagreements.
3. Negotiation-in the event that the contractor still does not agree and cannot settle among QS of both parties, it is only then that the variation is elevated to negotiation. And in times that QS from both parties cannot decide on particular issues, negotiation among PM is recommended to settle the variation.
4. Final Approval– will include informing the Accounting department for the additional cost due to the variation for budgeting and cash flow management.
Nonetheless, one of the common reasons for dispute is the valuation of variation. The current traditional approach has been claimed inadequate to provide a scheme of compensation for any delay or disruption involved due to variations. Actually, rules for variations, when appropriate, the rate and price quoted is used in the valuation for variations. However, the rate or prices may not necessarily be an accurate figure for individual work items. In other words, it represents the collective amount of the project. Therefore, the rules of valuation should not be implemented in a loose way, simply because the rates to which they are applied are imperfect.
A valuation scheme in valuing variations has been provided. The possible outcomes of the scheme when the valuation is to be determined are as follows:
1. Applying original rate and price from similar works in the bill of quantities.
2. Using the original rate and price of similar works as the basis of valuation, applying necessary adjustment and/or allowances.
3. Determining new rate and price derived from fair valuation.
However, there was an issue arise on this scheme as it is potentially creates conflicts and disputes. The conflicts and disputes has been identified, namely the distinction of the varied works compared to the original works, i.e. similar character and/or under similar conditions. In the case of similar work characteristics and/or work condition, the varied works are valued using the original rate and price of similar works in the Bill of Quantities. If the work character and/or work condition is not similar but in the opinion of the assessor is still appropriate, the original rate and price of similar works in the Bill of Quantities will be used as the basis of valuation applying necessary adjustment and/or allowances. If the work character and/or work characteristic are totally different from those mentioned in the Bill of Quantities, new rate and price will be established by fair valuation. A mechanism for valuation of variations is essential if our understanding of construction management is to be advanced.
On the other hand, difficulties may arise among the related parties in perceiving the conditions to be encountered during execution. Each party may perceive the works characters and/or work conditions differently according to the nature of their own needs and for their own benefits. A framework has been developed to fairly assess all changes resulted from authorized variations and relate the changes to the final decision of valuation method to be. The form of contract also has been especially drafted to accommodate the risks of different perceptions on this matter and distribute the risks fairly to the involved parties. This result in the recommended way to deal with variation events is to look back to the forms of contract to make a careful assessment.
Finally, based on the findings, it can be concluded that each of the condition of contracts has stipulated clearly the rules for method of valuing the claims of variation works. However, the adequacy and appropriateness of the mechanism are different based on the different types of contracts. The selection of the type of contracts to be used for a particular project may influence the project implementation in terms of contractual administration related to claims for variation works. By selecting an appropriate type of contracts for a project to be implemented may reduce the tendency of disputes arising from valuation of variation claims. Disputes related to claims of variation works can be avoided by overcoming the problems of the disputes. This may only be achieved through the proper selection of type of contracts which contain the most effective methods of valuing the variation claims. Despite the fact that BQ rates/Contract rates is the most instant method and agreeable among the contracting parties, it is recommended that this method should be improved by rationalization of the rates accordingly depend on the nature of the work of similar character executed under similar conditions. In other words, the BQ rates/Contract rates despite being the most agreeable rates they should be adjusted accordingly so that the rates for varied works will be fair to both contracting parties.
Recommendation
It is also suggested that the application of Information Technology by using an expert system as a potential decision-making tool in the valuation of variation claims to be further explored as it has the potential to deliver the best solution in the valuation of variations which based on the expertise of the professional decision-makers. It has been previously explored that the valuation of variations needs a mechanism that represents the expertise and knowledge of the human experts for its decision-making. Decision-making by experts regarding the valuation methods to be applied, based on the determination of the extent of the changes affecting the work characteristics and/or work condition, plays an essential role in the valuation scheme.
However, the majority of human decision making is answerable to more than a single person, and involves higher level functions that can be constrained and frustrated by any attempt to enforce rigid or methodical practices. In other words, consensus decision-making is required from several human experts for an appropriate decision. The human experts for the valuation of variations are the quantity surveyors due to their important role and involvement in financial and technical aspects of a construction project management.
Here are some knowledgeable key points to manage a Variation Order:
- Out-Source Information - for variations that need price comparison, outsource information must be obtained such as price indices from the government, quotations from suppliers and price information from consultants.
- Data collection – is to collect the correct information to support the validity of the any variation order. It can be Site Records such as site diaries, weather charts, site instructions, inspection reports, shop drawings and materials approval, RFIs and other forms of communication like emails, transmittals, minutes of meeting and project reports.
- Investigation - For variation order due to differing site conditions, site investigation is imperative. It is essential in determining the actual site situations and for observing if the proposed change were feasible to the site. It is also done to verify quantities, type of material applied by the contractor and to confirm the methods proposed for application for use.
- Know your references - reference materials would be the basis for evaluation first, entitlement of the contractor to a variation order, validity of the change, and determination of quantities either additive or deductive. Reference may include Construction Contract, Drawings, Specifications and other forms of site communications.

Abstract
Construction industry is often described as a volatile industry which can be true in implementing a project. Construction itself is more often unpredictable due to the different situations a project may face. Variations may occur in the preparation, during construction and even upon completion of the project. The veracity of inconsistent nature of construction, variation management procedures must be considered to minimize the effects particularly to project cost, time schedule and overall quality of the project.
There are an increasing number of construction contracts resulted in claims and disputes. All of the parties involved in the Thai construction industry are fully aware that disputes not only lead to cost overruns, but can end up as expensive and lengthy courtroom battles. However, very few studies related to construction contract claims and disputes in Thailand have been presented. This study is an attempt to gain further insight to construction contract claims and disputes in the Thai construction industry.
The big challenge for Thai Construction industry is to advance the management styles to cope up with challenges faced in a project. Procedures in managing contract and change orders are viewed to know the effectiveness and liability ensuing steps observed. Disruptions in cash flow and programme when mitigated and handled correctly may create confidence in handling changes that transpire in any project.
However, knowledge and skill in managing this challenging changes and observing effective procedures may eventually create a norm in Project Management system in the industry where tradition of strong relationship among Owner and Contract still prevails.
From the aforementioned information, it can be seen that the engineers have high levels of responsibility and must be knowledgeable and experienced in their work. They also have to work carefully to complete their work. Therefore, it is suitable for both engineers and involved personnel to study work data and past court cases that are related to their work, so that they can be careful about their work.
As abovementioned, Ms. Supatchana Pumpipat conducted a research studies for proper quantification of variation claims by emphasizing the varied works impact to cost structure which will be claimed by the contractors. Therefore, the major objectives for her study were to: (1) classify the variation works types in civil works of commercial building project and identify the problems that incurred in managing variation; (2) find out how to price the varied works that is generated from variation order that could be caused of claims and disputes; and (3) propose proper valuation process and the effective negotiation on the accepted price for both contractor and owner.
Conclusion
Based on the Case Study, the rebuilding shopping mall project garnered variation orders that were classified into five (5) categories such as:
i) New work – are the additional item in the some part of building for more suitable and aesthetic of the building. Frequently, this category is initiated by owner
ii) Modified work – are the existing of buildings becomes unsuitable for their present use, and then improvement, repair and maintenance are often required to keep them in usable condition.
Change work – are covered amend in some parts or whole scope of work that is stipulate in the contract
iii) Move work – are Moving things without creating any damage to those items including storage of those items, they assume a duty to be included in this section.
iv) Demolishing work – are move the existing part out and would not be reused. And the occupancy of debris that comes from the demolishing process will be agreed before starting work.
v) Correcting Work – items that are corrected or fix the damage of building. Most of them are architectural work.
At first, the author would like to identify the specific valuation method in each variation categories but based on interview, the valuation methods is not related to the variation categories. The valuation methods depend upon the condition and the character of the varied work.
The formulation procedure was initiated in order to manage the emerging variation orders. Basic flows of steps were provided but still flaws were found in processing time in every step. Some VO can be process without any difficulty and some may takes time to verify the submission documents, verify evidence, to gather data to confirm entitlement of the contractor to claim VO. Resolutions to variation order impact through variation order management were viewed and as to the effectiveness of current procedure. Current procedure is useful but can be developed to improve processing period and administer each changes lessening the probable effect to the whole project particularly on the cost.
Actually, the problems of this project are generated in every stage of variation procedure which will only base on the contractor’s viewpoint such as follows.
1. Notification - Information of change is given by either the PM or Contractors or whoever identifies the variation and all site instructions that may constitute a variation should readily indicate and require the Contractor to submit quotation. In the event that the Contractor submits a proposal like for example value engineering, this is the only time when the Project Management team conducts a preliminary analysis on time, cost, quality and the overall effects of the change in the construction.
2. Evaluation – the stage of gathering data to confirm support documents submitted by the Contractor. Determine the quantities, cost and time involved in the variation request. Coordinate the change with the trade in the construction for probable effect on the progress of the work and the work itself. At the same time coordinate with the contractor’s QS for comparison, checking and correcting evaluation. This will greatly discourage dispute in final cost later and save time on repeated evaluation in cases of disagreements.
3. Negotiation-in the event that the contractor still does not agree and cannot settle among QS of both parties, it is only then that the variation is elevated to negotiation. And in times that QS from both parties cannot decide on particular issues, negotiation among PM is recommended to settle the variation.
4. Final Approval– will include informing the Accounting department for the additional cost due to the variation for budgeting and cash flow management.
Nonetheless, one of the common reasons for dispute is the valuation of variation. The current traditional approach has been claimed inadequate to provide a scheme of compensation for any delay or disruption involved due to variations. Actually, rules for variations, when appropriate, the rate and price quoted is used in the valuation for variations. However, the rate or prices may not necessarily be an accurate figure for individual work items. In other words, it represents the collective amount of the project. Therefore, the rules of valuation should not be implemented in a loose way, simply because the rates to which they are applied are imperfect.
A valuation scheme in valuing variations has been provided. The possible outcomes of the scheme when the valuation is to be determined are as follows:
1. Applying original rate and price from similar works in the bill of quantities.
2. Using the original rate and price of similar works as the basis of valuation, applying necessary adjustment and/or allowances.
3. Determining new rate and price derived from fair valuation.
However, there was an issue arise on this scheme as it is potentially creates conflicts and disputes. The conflicts and disputes has been identified, namely the distinction of the varied works compared to the original works, i.e. similar character and/or under similar conditions. In the case of similar work characteristics and/or work condition, the varied works are valued using the original rate and price of similar works in the Bill of Quantities. If the work character and/or work condition is not similar but in the opinion of the assessor is still appropriate, the original rate and price of similar works in the Bill of Quantities will be used as the basis of valuation applying necessary adjustment and/or allowances. If the work character and/or work characteristic are totally different from those mentioned in the Bill of Quantities, new rate and price will be established by fair valuation. A mechanism for valuation of variations is essential if our understanding of construction management is to be advanced.
On the other hand, difficulties may arise among the related parties in perceiving the conditions to be encountered during execution. Each party may perceive the works characters and/or work conditions differently according to the nature of their own needs and for their own benefits. A framework has been developed to fairly assess all changes resulted from authorized variations and relate the changes to the final decision of valuation method to be. The form of contract also has been especially drafted to accommodate the risks of different perceptions on this matter and distribute the risks fairly to the involved parties. This result in the recommended way to deal with variation events is to look back to the forms of contract to make a careful assessment.
Finally, based on the findings, it can be concluded that each of the condition of contracts has stipulated clearly the rules for method of valuing the claims of variation works. However, the adequacy and appropriateness of the mechanism are different based on the different types of contracts. The selection of the type of contracts to be used for a particular project may influence the project implementation in terms of contractual administration related to claims for variation works.

Risk and Project Contract Management for Preventing and Solving Disputes in FIDIC Contract
A project is highly successful when risks are strictly controlled and the contract is effectively managed.
Mr. Dang Thai Son made a case study on the Can Tho Bridge Construction Project. In his study, the following core issues were aimed to achieve:
* To study issues on project risk management: implicit risks, the tenor and process of project risk management.
* To study issues on project contract management: signing and implementing the project contract, amending, canceling or terminating the contract.
* To find approaches to mitigate risks as well as to prevent and resolve disputes, litigations in project contract.
Conclusion
Risks are unavoidable in construction projects, yet it is still possible to prevent them before and during a project. With such a length (15.85 km), Cantho Bridge was a typical example for risk management. The project has received full financial support from the Japanese government which is Twenty Four Billion Eight Hundred Forty Seven Million Japanese Yen (¥24,847,000,000). However, there was still delay in land requisition. Although only two local households did not agree on their compensation, they affected the progress of the project. In addition, shipping equipment and complex custom procedures also hindered the progress.
On the better side, the Contractor has implemented good management starting with the designed hierarchy of management with well-targeted goals as well as backup plans. This helped the project progress even in case of force majeure. Second, the contractor had good management on quality and quantity on various aspects of working requirements such as materials, equipment, construction methods and skilled labors that were focused and well-prepared. Thirdly, the Contractor showed that environment was taken with extreme care so that almost no effects on the local landscape, and ecosystem were done by pollution from the construction. Finally, the Contractor always followed the most important motto: "Safety first." The disastrous accident in foundation settlement showed the nature of risk on one hand; but on the other hand, it showed that the Contractor prepared and implemented practical and helpful steps in preventing diseases and treating injuries to workmen. As a result, construction workers felt better and secure to continue their work and the project could be completed in due time.
After Can Tho Bridge was completed, it has provided the researcher with practical experience in terms of capital, specific infrastructure conditions, hi-tech quality of the contractor and compensation negotiation. This study showed that reality is always unexpected but with well-planned risk management, we can still handle and heal the uninvited damage to project effectively and in time so as to fulfill the project as pre-planned.
In conclusion, throughout the analysis, the Can Tho Bridge Construction Project achieved more successful factors than its constrained ones. This project obtained good delivery system from setting to closing out phase owing to good environments such as stable society economy and politics, favorably legal environment especially the great support from the project stakeholders: Financier (JIBIC), Owner, Consultant, Contractors, Suppliers and others (Local Authorities and so on).
Apart from the strengths achieved as analyzed, there are many weaknesses that the project stakeholders should pay much attention to and should take them as valuable recommendations for future projects:
- Before carrying out the construction of any project, the Project Owner together with Local Authorities shall ensure land requisition to be well-executed and give right of access and site possession to the Contractor at appropriate time without any delay and obstruction from local residents.
- When making the estimation for a project, besides calculating an official capital source for the main items of the project, the project planner should carefully calculate an extra money fund for nearby existing land compensation including the crops. Therefore, the Project Owner will be able to get sufficient land area and provide further access to the Contractor for construction. Because the construction activities of the Contractor definitely affect to the neighboring structures of the inhabitants.
- The Project Owner should thoroughly consider selecting competent, qualified contractors who are healthy in finance and capable of high technology. Not to give the award to the bidder of the lowest price, and poor equipment and poor technology transfer.
It was time for Vietnamese Government and its subordinating Ministries consider carefully when deciding to select the bidder especially for foreign ones. Before inviting them for bidding, a well pre-qualified selection of experienced, prestigious and competent bidder list should be made and elimination of unqualified bidders from the list should be done. If doing so, the Government saves a lot of time and money for unreasonable loss and damage from rectification of defects and re-works.

Abstract
Risk management is an indispensable job because it will help the project reduce and minimize the extraordinary impacts occur which affect to the general objective of the project.
In this study, we should learn about the concept of risk with its two specific characteristics: probability of occurrence and degree of impact. In addition, the classification of risk is also a meaningful deed; each kind of risk is different, therefore, risk management issue is also totally different. To manage risk, a process of six steps can be applied. First, making risk management plan for general orientation of work and scope of performance to manage the risks. Then, carrying out risk determination, it means to list out the risks might occur in the project. Since then analyzing probability of occurrence and the degree of impact of the risks, Control and adjustment of risks are to implement the plan for dealing with actual risks.
Contract management is extremely important in the project management. Referring to the contract, the project manager will treat and adjust the relationship as well as contradiction between interests and liability of the parties concerned in the project. Therefore, being a project manager, he or she needs to master the sequence of steps of signing and implementing the project contract, the arising issues and conditions of alteration, omission or termination of project contract as well as the approaches to resolve and settle disputes in the contract. Once dispute arises, it is wise that the parties should seek for negotiation, discussion or conciliation. This approach is simple, effective and little cost while claim and arbitration approach is more complicated, costly and waste of time.

Business Cooperation Contract Management in Gas Pipeline Project – A Case Study of Block B – O Mon Gas Pipeline Project
The signing of the business cooperation contract (hereinafter called BCC) to develop the Block B Gas Pipeline Project among PV Gas, Chevron, MOECO, and PTTEP will help to ensure the country's energy security and to promote industrial development in the Mekong Delta. The project will also save a significant amount of foreign currency for Vietnam on fuel imports, create more employment for the community, protect the environment by using a clean fuel, ensure a stable source of power, and open opportunities to connect with the gas pipeline systems of other countries in the region. However, how to well monitor and manage the pipeline project under the BCC is the challenge for operator.
Under BCC, each party will appoint a representative to the board of coordinators (hereinafter called BoC) to provide overall supervision and direction over and control all matters pertaining to the system operation. Therefore, the operator cannot decide on its own for the system operation which may lead to run late project, over-budget or fail to meet key needs of parties and so on. There are definitely some shortcomings in project under BCC need to be over, that are:
i. Take time for mutual agreement among parties;
ii. Misunderstanding and misinterpreting of stipulated clauses in contracts
iii. Conflict between contractor and the project company during project execution
iv. Conflict between cultures
A BCC is generally applied for managing the oil and gas project, in case of problems or disputes happen during the project execution, then these problems and disputes shall be resolved in accordance with stipulated clauses in the signed contract, therefore Mr. Phung Quang Hiep made a case study which main object was to focus the Phung Quang Hiep
issues related to BCC:
1. To study BCC contract objectives
2. To study BCC contract conditions
3. To study BCC contract implementation and problems occurring
4. To propose effective solutions for project management under BCC
Conclusion
BCC Objectives:
The purpose of this report is to describe the BCC objectives in which the project is implementing the design, procurement, construction, ownership, operation, maintenance of the upstream Block B & 48/95 and Block 52/97 facilities to ensure economic, efficient System development on an integrated, aligned basis, as set forth in this Contract.
BCC Conditions:
These objectives are concretized under BCC conditions of conditions precedent and participating interest. Block B – O Mon pipeline project has some difference phases. Therefore, the writing displays them in three main groups of technique, finance and legality. Technical phases include construction, operation and maintenance of system; transportation proposal and capacity; usage of the system, transportation of gas and tariffs; as well as decommission. In addition, financial issues of BCC are focused on taxation; government and corporation support; work program and budget; and contracting procedures. Also, BCC requires legal items in operation that are, insurance and litigation; default, assignment of participating interest; withdrawal; and dispute resolution.
BCC Implementation And Problems:
The above analysis is to result to business cooperation contract management for block B – O Mon pipeline project through making up factors affecting to take time for mutual agreement among parties, underground drivers of misunderstanding and misinterpreting of stipulated clauses in contracts and conflict between contractor and the project company during project execution as well as conflict between cultures. To response to these problem statements, this report concentrates on studying problems occurring and proposing effective solutions for project management under BCC as well.
This project may be continued if precedent conditions are satisfied or waived. That foreign- factors take part in business of gas pipeline and that disadvantages are caused by BCC have created some outstanding problems to system operation. The report asserts that issues of finance, accounting, culture, legality, risks, approval and human resource are needed to analyzed, improved and boosted. Otherwise, project will be delayed in the manner of time and quality and not achieved project objectives.
Effective Solutions for Project Management under BCC:
For finance and accounting issues, the operator has to harmonize regulations between BCC and Vietnamese Corporation Accounting which is first priority while the parties are required to obtain deep understanding of investee country, that is, Vietnamese laws. Moreover, due to four different management cultures the operator should set up harmonious business culture, seminars, team build to interpersonal communication and friendly atmosphere and especially maintain internal control of approval procedure and authorization for expenditure procedure. A unified and well defined organizational chart for human resource management is so important for continuous system operation. All above is to minimize business risks led by project specialization.
In addition, the report shows out main experience lesson groups to solve these problem statements. First, the operator should take full advantages of local authorities and governmental support in all tax and foreign currency issues. Second, the operator needs to have closer direction and management of higher authorities to keep the project be in the right way. Third, taking an initiative of finance, positioning negotiators of BCC in the board of operator and maintain frequently periodic meeting are considered as meaningful recommendations to unbind stuck bars during implementing project and achieve project objectives in timely and quality basis.

Abstract
Natural gas is a fossil fuel extracted from the ground that can be used as a source of energy for household, industrial and commercial use, as well as to generate electricity. So, natural gas is an important factor for the development of countries that have strong economies and people who enjoy good living conditions. To be able to have a viable and efficient supply requires the construction of a pipeline from faraway regions that have large reserves of natural gas to onshore terminals. In Vietnam, the projects of pipeline construction and operation are almost under direct foreign investment of which business cooperation contract is the most favor.
The management of this contract is a challenge to Vietnamese operator due to foreign factors. This report let a case of BCC for block B – O Mon pipeline project as a study of project management in construction. It tries to work out common and regular problems this kind of BCC is encountering. These difficulties are divided into four groups that are, take time for mutual agreement among parties, misunderstanding and misinterpreting of stipulated clauses in contracts and conflict among contractors and the operator during project execution as well as conflict among cultures.
Moreover, BCC conditions and project phase operation are analyzed in details. Above all, the author suggests some solutions focusing on outstanding problem statements to improve the project operation and implement it in the manner of time and quality.
Under BCC, each party will appoint a representative to the board of coordinators (hereinafter called BoC) to provide overall supervision and direction over and control all matters pertaining to the system operation. Therefore, the operator cannot decide on its own for the system operation which may lead to run late project, over-budget or fail to meet key needs of parties and so on. There are definitely some shortcomings in project under BCC need to be over, that are:
i. Take time for mutual agreement among parties;
ii. Misunderstanding and misinterpreting of stipulated clauses in contracts
iii. Conflict between contractor and the project company during project execution
iv. Conflict between cultures
A BCC is generally applied for managing the oil and gas project, in case of problems or disputes happen during the project execution, then these problems and disputes shall be resolved in accordance with stipulated clauses in the signed contract, therefore Mr. Phung Quang Hiep made a case study which main object was to focus the Phung Quang Hiep
issues related to BCC:
1. To study BCC contract objectives
2. To study BCC contract conditions
3. To study BCC contract implementation and problems occurring
4. To propose effective solutions for project management under BCC
Conclusion
BCC Objectives:
The purpose of this report is to describe the BCC objectives in which the project is implementing the design, procurement, construction, ownership, operation, maintenance of the upstream Block B & 48/95 and Block 52/97 facilities to ensure economic, efficient System development on an integrated, aligned basis, as set forth in this Contract.
BCC Conditions:
These objectives are concretized under BCC conditions of conditions precedent and participating interest. Block B – O Mon pipeline project has some difference phases. Therefore, the writing displays them in three main groups of technique, finance and legality. Technical phases include construction, operation and maintenance of system; transportation proposal and capacity; usage of the system, transportation of gas and tariffs; as well as decommission. In addition, financial issues of BCC are focused on taxation; government and corporation support; work program and budget; and contracting procedures. Also, BCC requires legal items in operation that are, insurance and litigation; default, assignment of participating interest; withdrawal; and dispute resolution.
BCC Implementation And Problems:
The above analysis is to result to business cooperation contract management for block B – O Mon pipeline project through making up factors affecting to take time for mutual agreement among parties, underground drivers of misunderstanding and misinterpreting of stipulated clauses in contracts and conflict between contractor and the project company during project execution as well as conflict between cultures. To response to these problem statements, this report concentrates on studying problems occurring and proposing effective solutions for project management under BCC as well.
This project may be continued if precedent conditions are satisfied or waived. That foreign- factors take part in business of gas pipeline and that disadvantages are caused by BCC have created some outstanding problems to system operation. The report asserts that issues of finance, accounting, culture, legality, risks, approval and human resource are needed to analyzed, improved and boosted. Otherwise, project will be delayed in the manner of time and quality and not achieved project objectives.
Effective Solutions for Project Management under BCC:
For finance and accounting issues, the operator has to harmonize regulations between BCC and Vietnamese Corporation Accounting which is first priority while the parties are required to obtain deep understanding of investee country, that is, Vietnamese laws. Moreover, due to four different management cultures the operator should set up harmonious business culture, seminars, team build to interpersonal communication and friendly atmosphere and especially maintain internal control of approval procedure and authorization for expenditure procedure. A unified and well defined organizational chart for human resource management is so important for continuous system operation. All above is to minimize business risks led by project specialization.
In addition, the report shows out main experience lesson groups to solve these problem statements. First, the operator should take full advantages of local authorities and governmental support in all tax and foreign currency issues. Second, the operator needs to have closer direction and management of higher authorities to keep the project be in the right way. Third, taking an initiative of finance, positioning negotiators of BCC in the board of operator and maintain frequently periodic meeting are considered as meaningful recommendations to unbind stuck bars during implementing project and achieve project objectives in timely and quality basis.

Abstract
Natural gas is a fossil fuel extracted from the ground that can be used as a source of energy for household, industrial and commercial use, as well as to generate electricity. So, natural gas is an important factor for the development of countries that have strong economies and people who enjoy good living conditions. To be able to have a viable and efficient supply requires the construction of a pipeline from faraway regions that have large reserves of natural gas to onshore terminals. In Vietnam, the projects of pipeline construction and operation are almost under direct foreign investment of which business cooperation contract is the most favor.
The management of this contract is a challenge to Vietnamese operator due to foreign factors. This report let a case of BCC for block B – O Mon pipeline project as a study of project management in construction. It tries to work out common and regular problems this kind of BCC is encountering. These difficulties are divided into four groups that are, take time for mutual agreement among parties, misunderstanding and misinterpreting of stipulated clauses in contracts and conflict among contractors and the operator during project execution as well as conflict among cultures.
Moreover, BCC conditions and project phase operation are analyzed in details. Above all, the author suggests some solutions focusing on outstanding problem statements to improve the project operation and implement it in the manner of time and quality.

Project Schedule Internal Risk Management in EPC Gas Pipeline Project: A Case Study
Oil and gas sector is considered as a backbone of any country’s economy. In Viet Nam, the promotion of gas industry development since the early 1990s has significantly contributed to the economic development of the country.
The demand of domestic gas consumption is being increased in a very short time. Therefore, Petro Vietnam has cooperated with national and international petroleum companies to speed up the plan of developing and building of the new gas fields in the southeast sea and southwest sea of Vietnam. As a result, lot of new pipelines will be installed to transport gas from field to shore of Vietnam, and this process involves many risks. Due to the unique characteristic of this project, the risk management during project execution became very important activity because the risks may have effect on cost, schedule and quality of the project. Risk management is a key to successful project implementation.
For most effective and efficient risk management, it is recommend to plan, analyze and manage risk in all phases of project life cycle specifically from design to construction phase.
Mr. Pham Binh Lam made a case study which objectives were to: (1) describe key activities in EPC gas pipeline project ; (2) identify risk factor in implement the EPC gas pipeline project which may affect the project schedule; and (3) propose risk solution that can be used to manage in the EPC gas pipeline project
Conclusion
Based on the data collected mainly from Bloc B&52-Omon gas pipeline project of Petro VietNam Gas Corporation, the author has clarified that EPC gas pipeline project contains high risk during project execution. The very important stages are from engineering stage to construction stage because these stages influence the quality of gas pipeline project. There are a lot of risk factor impacts on the project schedule in these periods such as experience, knowledge and skill of owner, contractor, subcontractors, design change, and environment impact. Pipeline construction in the offshore environment as well as onshore environment which across many rivers and canals are difficult and dangerous activity which lead to accidents and incidents frequencies happen especially if this project have a long distance from offshore to onshore pipeline route. It will not only cause project delays but also directly and indirectly cause very high project cost.
Major risk factors which may affect EPC gas pipeline project schedule has been identified by and facilitated during the brainstorming session of key experience stakeholders in this project such as top management, project manager, site manager, HSE manager, office personnel and the author.
The author has proposed appropriate strategies to reduce major risks schedule in EPC gas pipeline project by conducting a Framework on EPC Schedule Risk Management through a real gas pipline project case study -Block B – Omon gas pipeline project.The results are shown in the table below.
Recommendation
In order to obtain efficient schedule risk management in EPC gas pipeline project this study proposes a number of recommendations:
- Experience project management team should be appointed to the selection EPC contractor
- The EPC contractor has to contribute audit procedure for detailed designer to select qualified designer effectively. In addition, review and approval by Project Management team (PMT) of both selection of detailed designer and approval of designed document
- The EPC contractor and subcontractor should contribute an effective and efficient safety management system
- An effective communication and coordination system between lower stake holder (e.g. EPC contractor, subcontractor, vendor, etc) should be set up
- The owners should have high commitment of all people involved especially top management commitment in all stage of project and hand over authority to make decision.
- The Risk Management Plan should be reviewed during the EPC phase as specified in the Project Management Plan to ensure that appropriate actions have been taken and followed up. Reviews should also occur at the commencement of a new project phase or if there are significant changes to the project scope or operating environment.

Abstract
In order to adapt the demand of domestic gas consumption is being increased in very short time PetroVietnam has cooperated together with national and international petroleum companies to speed up the plan of developing and building new gas fields in the southeast sea and southwest sea of Vietnam. Therefore a lot of new pipelines will be installed to transport gas from field to shore of Vietnam. In oil and gas project specify gas pipeline project contains high risk during project execution because of interacting activities of many event in condition of limited time, human resource and budget and the participation of many different parties in the project with the role, responsibilities as well as different objectives make the project more complex. Additional, only four gas pipelines project that built in Vietnam. Due to the unique characteristic of these project, the risk management during project execution is became very importance activity because the risks effect on cost, schedule and quality of the project. Risk management is a key to successful project implementation The author has identified mayor significant risks which impact project schedule and has proposed appropriate strategies to reduce major risks schedule in EPC gas pipeline project by conducting a Framework on EPC Schedule Risk Management through a real gas pipeline project case study -Block B – Omon gas pipeline project.
