After implementing the first stage of the quality assurance and product improvement in construction program, Vietnam Minister of construction assessed that although the program has achieved success in the first stage, there are some difficulties need to be overcome comparing with the goal and requirements planned. Annually, accidents still happen on working site due to violation of quality management process and procedure. Lacks of owner’s care, some commissioning buildings have no operation and maintenance manuals. This leads to degradation, reduction of the building’s life span and become unsecured in operation (instruction of Vietnam Ministry of construction, 2006).
Quality in construction is measured through time, cost and scope in traditional way. Andrew argued that these indicators are simple and crude to gauge the project quality. Owners are more quality-driven than price and value driven (Dainty, 2003). Especially, in oil and gas facilities, expensive equipments related to each other in manufacturing line. If one component fails, the other will be affected like the domino effect. So it is necessary to recognize other components affecting construction quality in each stage of project life cycle through assessing effectiveness and efficiency of construction processes. From that point, processes can improve that satisfy the external and internal customers. As a result, the existence and success of Vietnam enterprises are confirmed in local and international arena as well.
Mr. Duong Thanh Hai made a study which main three objectives were: (1) modeling the construction quality assurance activities from design to commissioning in traditional procurement; (2) investigating problems in term of effectiveness and efficiency of processes and sub-processes in the model that affect quality issues; and (3) developing a tentative model that incorporates construction activities and quality improvement approaches addressing such problems.
Conclusion
1. Modeling the construction quality assurance activities from design to commissioning in traditional procurement
The case was the storage tank project using design-bid-build procurement approach. The owner had in-house staff working as construction management. The owner stated their needs to design consultant. The designer mapped out all construction law, codes and standards that have to be complied with and to control and assure project quality.
Based on the design, the owner gave the quality requirements to site surveyor, supervisor, and contractor. Then these people submitted their quality plans that satisfy those requirements. A quality assurance model was developed based on the discussion with project participants and analyzing archive. The model shows interaction among involved parties from design to commissioning.
2. Investigating problems in term of effectiveness and efficiency of processes and sub-processes in the model that affect quality issues
There were five major problems happened in the project because the involved parties violated the quality plan and also because of the gaps on those quality plans itself.
Problem 1: design materials unavailability in the market
The design materials are only available during the time that the consultant planned the design. During the procurement, the owner realized shortage then the designer had to re-work.
Problem 2: delay in pressing piles
Although all operating procedures were clearly stated in the quality plans, mistakes still took place. The bearing capacities of pressed piles were not the same as the designed figures. According to the plan, the contractor would have informed the designer when problems happened but they did not. As a result, the schedule was delayed.
Problem 3: supply delay of floating roofs
Floating roof equipments were supplied two months late. Those equipment trades were solely based on contract which the contractor cannot assure the supply on time. The contract had just compensated direct loss for contractor. Other indirect loss such as reputation, administrative, low morale actually cannot be recovered.
Problem 4: valves leakage
Design valves were not received on time because of the delay in supply. The contractor used temporary valves to replace designed valves during tank process testing. Unfortunately, the temporary valves cannot bear the oil load, so they leaked. Some arrangements should be carried out to make sure that supplies are available when needed rather than recovered from contract breach penalty.
Problem 5: oil leakage of existing tank system
Underground pipeline were maintained every 10 year. However, those pipelines failed one year before that time. Therefore, one burning accident happened during the transferring process of existing tanks. The underground pipeline should be monitored gradually during that period.
3. Developing a tentative model that incorporates construction activities and quality improvement approaches addressing such problems
In Petromekong, most of construction applied traditional procurement. Contractor requested for supplier’s quotation after they had got bid. However in oil and gas industry, oil constructions usually need long lead time materials and equipment. For this reason, the contractor faces delay of supply sometimes. The study illustrated “supplier partnership” approach should be used in such type of construction to improve procurement quality. Petromekong in-house investing department will arrange partnership with suppliers beforehand. Then the owner, suppliers, designer will optimize time, cost, quality and satisfaction trade-off for important long lead time equipments and materials.
A chain of tools is suggested to detect and solve those problems in advance. Quality improvement tools such as flowchart, check sheet, problem source investigating chart, brainstorming, affinity diagram, fish bone diagram, nominal group technique should be used orderly to improve certain construction processes. Such types of process are repetitive, measurable and have clear procedures. Company can monitor and record performance of those processes regularly. Whenever problems happen, company can immediately recognize warning signs and take actions beforehand.

Abstract
Since Vietnam has had oil terminal system development plan, more tank projects have been invested to expand storage capacity. However, quality violation has been alert obviously. From that point, the study suggests model to identify and eliminate those problems beforehand.
The study used one tank project as case study to fulfill three objectives. Firstly, quality assurance processes in traditional procurement were modeled. Then, the researcher investigated problems adhering to these processes. Finally, an improving quality model was suggested addressing those problems.
The case study was collected from Petromekong Corporation located in southern part of Vietnam. The researcher utilized focus group qualitative method. The researcher discussed with investing department of Petromekong to elicit quality assurance activities of project participants. Then, the researcher defined five problems existing in the case: deigning unavailable material on market, delaying in pressing piles, supply delay of floating roofs, leakage of valves and oil leakage of existing tank system. The researcher looked for some quality improvement approaches from manufacturing industry since. Finally, after conducting expert’s assessment, the researcher demonstrated “supplier partnership” approach should be used in long lead time materials and equipment construction to improve procurement quality. Illustrating pile driving and oil transferring processes as examples, the researcher suggested a chain of tools to detect and solve those problems in the case study beforehand. Such tools are flowchart, check sheet, problem source investigating chart, brainstorming, affinity diagram, fish bone diagram, nominal group technique should be used orderly to improve repetitive, measurable and clear procedure construction processes.
Key word: quality assurance, Petromekong, oil storage tank, traditional procurement, quality improvement, construction problems, case study, Vietnam.

Public Private Partnership in Low-Income Housing Development in Vietnam
Infrastructure development plays a vital role in economic growth and poverty reduction (WB, 2003). Traditionally, infrastructure systems have been provided by public sector. However, the increasing need of new infrastructure development and maintenance of existing infrastructure systems demands a huge capital investment which cannot be achieved by public fund. Public-Private Partnership delivery has become a solution for funding problem by mobilizing private sector fund into infrastructure investment (ADB, 2008). With their innovation and management skill, private participation can increase productivity and efficiency of operation, improve the quality of service and reduce service price compared to public sector provision (ADB, 2008).
In order to keep pace with the increase in housing demand and improve poor housing condition, scaling up investment in housing sector is the urgent focus of Vietnamese government. And in order to reduce state budget investment, Vietnam government is currently seeking possible solutions to develop public private partnership in infrastructure investment, and especially in low-income housing development.
Mr. Truong Ngoc Quy made a study which main objective is to propose the possible solution to encourage private participate in low-income housing development in HCMC. In accomplishing the main objective, the following sub-objectives have to achieve:
1. Develop general public private partnership framework in low-income housing development and its assessment criteria.
2. Investigate current practice of public private partnership in low-income housing development in Vietnam using the developed general model
3. Assess current practice of public private partnership of low-income housing development in Vietnam based on developed assessment criteria.
4. Propose the recommendation for setting up applicable public private partnership model in low-income housing development in Vietnam.
Research Findings
1. General public private partnership model in low-income housing development and its assessment criteria
Five factors of PPP in LIH development which are constructed from extensive literature review and expert verification are (1) government support to private participation, (2) government imposition on private party, (3) government subsidies for low-income people, (4) control target group policy, and (5) tenure system. Also from literature review and expert verification, the nine assessment criteria which are constructed and divided into 3 groups related to three main parties in low-income housing development are (1) affordability, accessibility, and availability for low-income people (2) profitability, availability, accessibility of incentives for private developers (3) sustainability, effectiveness, and inclusiveness.
2. Investigate current practices of public private partnership in low-income housing development in Vietnam
Many issues related to government support for private sector, imposition on developers, subsidies for LIP, control of target group, and tenure system in Vietnam. Facing the problem related to government support, private developers in Vietnam cannot receive some important incentives such as land and financing subsidies which are promised to give by government. The maximum profit margin of 10% and minimum cost recovery at least for 10 years for both hire-purchase and installment payment or for 20 years for rental houses make this market segment unattractive to private sector. The minimum planning and designing standard, and controlling maximum profit margin are lack of detail guideline for public authority and private developer during implementation. The housing finance subsidy in government policy is not strong to provide affordable loan condition to low-income people. Moreover, the loan condition actual provided to LIP is less favorable than what is introduced in policy. Because of under-table money using in allocation system and lack of detailed guidelines to prevent resale and renting out allocated units, most of the housing units are occupied by ineligible people. The actual tenure system is less favorable to low-income people than the imposed tenure system in government policy due to lack of profit in planning tenure system of government policy.
3. Assess the current practice of public private partnership in low-income housing development in Vietnam
Most low-income people in Vietnam face difficulty in affording payment condition and serving debt due to high debt service, high portion of down payment, and high housing price. The quantity of housing available to LIP is low, and the housing finance subsidy is also low in term of both quantity and quality. Housing subsidies including low-income housing subsidized units, housing finance and subsidized information is difficult to access for LIP. The low-profit margin and long term cost recovery set by government is not attractive for private participation. Some important incentives such as off-take guarantee and faster legislation procedure are not introduced in government policy and most incentives in government regulation are not provided in reality. Moreover, most provided incentives such as tax, financing, and basis infrastructure are not given to developer because they are not included in project cost when calculating profit margin. Complex legislation procedure in receiving incentives makes it difficult for developer to access these incentives. The LIH program does not provide housing for migrant and not focus on non-government officials due to its strict selection criteria, and does not cover other housing need due to unsuitable minimum design standard. Another issue related to effectiveness of program is that it is not effective in attracting private participation due to low profit set by government, reducing housing price because of the profit margin ceiling policy, and allocating housing to eligible people due to under-table money using and unclear controlling guideline after sale. Because of its low actual incentives and low actual subsidies provided, the financial sustainability of government budget is not affected much.

ABSTRACT
One of global problem is inadequate condition of urban housing, and it is most serious issues in developing countries. The pressing issue of Vietnam at the mean time is providing adequate housing for residents, especially for poor people living in urban area. In order to reduce state budget investment in housing development for the poor, Vietnam government is currently seeking possible solutions to develop public private partnership in low-income housing development. However, it is still lack of public private partnership in low-income housing development even though government has implemented incentives policy to encourage private participation since 2001. The purpose of this study is seeking possible solution to develop practice of public private partnership in low-income housing development.
This research was conducted by case study methodology to fulfill four study objectives. Firstly, general framework and its assessment criteria for public private partnership in low-income housing development were developed and verified by expert. Secondly, the current practices of public private partnership in low-income housing development in Vietnam are investigated base on developed general framework. Thirdly, following developed assessment criteria, the current practices of public private partnership in low-income housing development in Vietnam are assessed. Fourthly, recommendation for setting up applicable public private partnership in low-income housing development in Vietnam is made.
The result of this study found there is a big gap between government policy and actual implementation of public private partnership in low-income housing development in Vietnam. The government program is not effective in solving housing needs. Low-income people still face difficult in buying the houses. The low-income housing market is not attractive to private developer. Housing finance institute, housing saving fund, and national housing authority are recommended to be set up and play important roles in supporting both demand side and supply side of low-income housing market.

Development of a Worker Engagement Measurement Tool (WEMT) for Construction Safety Program
Many studies revealed that construction industry has the highest risks compared with other industries, risks that sometimes lead to death.
Each construction companies have their own safety measures implementation. But how to lessen if not totally eliminate this kind of accidents is everybody’s concern especially those who are working in the construction sites.
Dr. Oulawan Kulchartchai made a research to find the answer to the following questions:
• How can worker engagement in safety program implementation be assessed?
- What process should be used to develop Worker Engagement Measurement Tool (WEMT)?
- What are the components/elements of worker engagement?
• What are the factors that affect worker engagement in safety program implementation?
• What are the critical factors contributing to the success of worker engagement in safety program implementation?
The general objective of her research is to develop an assessment tool to measure worker engagement in the safety program implementation. This assessment should allow managers to assess the real status of their workers from the workers’ views, and then provide adequate actions to improve worker engagement. To accomplish these, the specific objectives of the study are set out and identified as the following:
• To develop a reliable assessment tool in order to measure worker engagement in safety program implementation in construction projects.
• To identify critical factors of successful worker engagement (WE) in safety program implementation
Conclusion on Answers to the Questions
In assessing the worker engagement in safety program implementation, two questions must be addressed: first; what are the components/elements of worker engagement? And second; what is that the process that should be used to develop worker engagement measurement tool?
On assessing worker engagement in safety program implementation:
a. What process should be used to develop Worker Engagement Measurement Tool (WEMT)?
The literature reviewed revealed that there is a lack of empirical data on many of the measures of an engagement in construction area, particularly for the workers. The development of a worker engagement measurement tool, which is perceived to be valid, should clearly reflect the emerging research perspectives on engagement. The tool should look at the total context (cognitive, affective, and psychomotor domain) and not focus on a singular dimension (the degree of freedom for workers to make their own decisions regarding health and safety issues).
Ground theory analysis was adopted to define the concept ‘worker engagement’ and associated descriptive elements.
Lawshe's (1975) quantitative content validity technique was used to determine the perception of safety experts based on the model or framework on worker engagement and its descriptive elements. The results derived from the content validity technique showed that fifty-three (53) out of the seventy-eight (78) descriptive elements were included in the validity assessment questionnaire of a worker engagement). The element consisted of cognitive domain (21 items), affective domain (26 items), and psychomotor domain (6 items), and content validity index as perceived by safety experts which are 0.72, 0.60, and 0.43 respectively. It can be concluded that the theoretical construct of the worker engagement model and descriptive elements were verified and thus acceptable for use in the development of a worker engagement measurement tool.
b. What are the components/elements of worker engagement?
To determine the components/elements of worker engagement, a process was needed to initially develop a worker engagement measurement tool. By using triangulation techniques, models including the scale development process were developed. This process was also used by Du Plessis (2004), and was based from DeVellis’s work (1991) as supported by the latter study from Clark and Watson’s (1995). The theoretical model construct was derived from the related literature study. To get the descriptive elements of worker engagement, Grounded Theory’s techniques were applied. The data was verified by safety experts using Lawshe’s techniques. The verified items were subjected to item analysis and exploratory factor analysis techniques using SPSS (Statistical Package for the Social Sciences) software. The reliability test in SPSS was adopted through the Independent sample, t-test.
In conclusion, the questions above could be positively answered from the literature reviewed and qualitative study. These answers provided the background to the empirical part of the study and supported the inputs to the primary objective.
The secondary objective of this study is ‘to identify critical factors of successful worker engagement (WE) in safety program implementation’. To accomplish this objective, two steps were considered: (1) the common factors affecting worker engagement in safety program implementation; and (2) the critical factors contributing to the success of worker engagement in safety program implementation.
Based on a learning theoretical model, factors affecting worker engagement in safety program implementation can be grouped into situation related factors and individual related factor. Although many psychological and management literatures have studied engagement factors, little work in current literature attempted to explore the factors contributing to worker engagement in safety programs implementation at construction projects. Therefore, the qualitative and quantitative studies were carried out.
In order to identify the affecting factors, a qualitative study was done using the Grounded Theory’s technique. Subsequently, the factors were verified using Lawshe’s techniques. The results indicated that affecting factor consists of situation-related factor (31 items) and individual related factors (12 items) and the content validity index as perceived by safety experts are 0.56 and 0.59 respectively. It can be concluded that the affecting factors which were perceived by experts were valid.
Conclusion and Answer to the Primary Objective Worker Engagement Measurement Tool (WEMT)
A worker engagement measurement tool (WEMT) was developed. This tool has a six-factor scale and a total of 39 items. This was derived from applying the research process which included Grounded Theory’s techniques, Lawshe’s techniques, the development of a scale instrument by using DeVellis’s (1991) process, and a reliability test of the developed worker engagement measurement tool by using Independent sample, t-test
The statistical techniques such as item analysis and exploratory factor analysis in SPSS was applied on the initial 78 variables under the three construct theoretical model developed from a learning theory and Kahn’s initial theoretical model, then worker engagement concept and associated descriptive elements were identified by utilizing Grounded theory and then verified by safety experts.
The final conclusion that can be made to answer the primary research objective is that the worker engagement measurement tool (WEMT) developed through this research is holistic in nature and measures a total worker engagement construct by means of the six factors; is reliable (statistically proven); can be used as a diagnostic tool because it can significantly distinguish between projects; and is perceived to have a valid construct.
Conclusion and Answer to the Secondary Objective Factor Affecting Worker Engagement
The factors affecting worker engagement consisted of six factors and had 29 items in total. This data was the output from series of analysis. After numerous literature researches, the theory was found relevant to this study.
The final conclusion answers “what are the critical factors contributing to the success of worker engagement in safety program implementation?” Safety policy, supportive management and supervisor behavior factor, and individual related factors were considered as the critical factors affecting to worker engagement in safety program implementation, whereas, workplace climate, communication and feedback, and reward and recognition were perceived by the respondents as the factors that need considerable attention in order to improve worker engagement in safety programs implementation.

ABSTRACT
The construction industry is considered to have the highest rate of fatal occupational injuries in many countries. In Thailand, the accident rate in the construction industry is reportedly the highest compared to other industries. Fatal injuries to workers occur more often in construction industry. Previous research emphases often analyze the effective safety programs rather than those that are geared towards creating safe working environments. Workers are expected to play and act as the “key driver” in safety program implementation. Due to this, worker engagement is now considered to be one of the most important approaches in reducing work-related injuries and diseases. Without this worker engagement, safety programs will be difficult to achieve. It is hypothesized that worker engagement can substantially reduce accidents and improve safety performance continuously.
The primary objective of this study was ‘to develop a reliable assessment tool to measure worker engagement in safety program implementation in construction projects” and ‘to identify critical factors of successful worker engagement (WE) in safety program implementation’. The findings therefore will enable construction firms to identify gaps in worker engagement within the safety program implementation, and facilitate improvements.
This study used triangulation techniques including; theoretical model construct by a thorough literature study, components of worker engagement indicated by Grounded Theory’s techniques, verification of the theoretical model using Lawshe’s techniques, the development of a scale instrument by using DeVellis’s (1991) process supported by Clark and Watson’s (1995) and used by Du Plessis (2004), a reliability test of the developed worker engagement measurement tool by using Independent sample, t-test.
In developing the WEMT, several consultation and tests were conducted with national safety experts. Results showed that worker engagement (WE) consisted of 3 domains; cognitive (21 items), affective (26 items), and psychomotor (6 items). The content validity index of the domains according to safety experts are 0.72, 0.60, and 0.43 respectively. Additionally, the situation-related factor (31 items) and individually related factors (12 items) with respect to the content validity index were 0.56 and 0.59 respectively. A questionnaire with 53 variables in three dimensions of worker engagement and 43 variables in affecting factor was distributed to the sample group of construction workers and personnel basis either by electronic-mail or hand carried to the representative sample group of 494. Approximately fifty two percent (258/494) responded anonymously. A scale instrument was developed through the item analysis and exploratory factor analysis function of the Statistical Package for the Social Sciences (SPSS).
A worker engagement measurement tool (WEMT) comprised of 39 items in a six-factor instrument was developed. It was found that the items in these factors were highly acceptable, receiving a Cronbach alpha coefficient above 0.8.
The developed WEMT was tested in two distinct construction projects in Oil&Gas and Building projects. These test confirmed that WEMT was a reliable diagnostic tool that can discriminate worker engagement level among different projects, particularly in the Thai construction firm context.
This research also determined factors that affect worker engagement within the safety program implementation. These factors are important when guided contractors to increase worker engagement level. This study showed that suitable safety policies, a supportive management team, and individually related factors were critical and directly affects the worker engagement in safety program implementation. Workplace climate, communication and feedback, and reward and recognition were perceived by the respondents as the factors that need considerable attention to improve worker engagement.
This research is relevant because it was able to identify a reliable worker engagement measurement tool that enables projects to identify the overall level of worker engagement in safety program implementation. This tool will serve to facilitate strategic actions to improve the working situations, thereby optimizing safety program implementation for continuous safety movements. The implementation of such strategies will be a forward move towards beginning and sustaining safety program implementation for further safety performance improvement within industries, particularly in Thailand.

A worker engagement measurement tool (WEMT) was developed. This tool has a six-factor scale and a total of 39 items. This was derived from applying the research process which included Grounded Theory’s techniques, Lawshe’s techniques, the development of a scale instrument by using DeVellis’s (1991) process, and a reliability test of the developed worker engagement measurement tool by using Independent sample, t-test
The statistical techniques such as item analysis and exploratory factor analysis in SPSS was applied on the initial 78 variables under the three construct theoretical model developed from a learning theory and Kahn’s initial theoretical model, then worker engagement concept and associated descriptive elements were identified by utilizing Grounded theory and then verified by safety experts.
The final conclusion that can be made to answer the primary research objective is that the worker engagement measurement tool (WEMT) developed through this research is holistic in nature and measures a total worker engagement construct by means of the six factors; is reliable (statistically proven); can be used as a diagnostic tool because it can significantly distinguish between projects; and is perceived to have a valid construct.
Conclusion and Answer to the Secondary Objective Factor Affecting Worker Engagement
The factors affecting worker engagement consisted of six factors and had 29 items in total. This data was the output from series of analysis. After numerous literature researches, the theory was found relevant to this study.
The final conclusion answers “what are the critical factors contributing to the success of worker engagement in safety program implementation?” Safety policy, supportive management and supervisor behavior factor, and individual related factors were considered as the critical factors affecting to worker engagement in safety program implementation, whereas, workplace climate, communication and feedback, and reward and recognition were perceived by the respondents as the factors that need considerable attention in order to improve worker engagement in safety programs implementation.

ABSTRACT
The construction industry is considered to have the highest rate of fatal occupational injuries in many countries. In Thailand, the accident rate in the construction industry is reportedly the highest compared to other industries. Fatal injuries to workers occur more often in construction industry. Previous research emphases often analyze the effective safety programs rather than those that are geared towards creating safe working environments. Workers are expected to play and act as the “key driver” in safety program implementation. Due to this, worker engagement is now considered to be one of the most important approaches in reducing work-related injuries and diseases. Without this worker engagement, safety programs will be difficult to achieve. It is hypothesized that worker engagement can substantially reduce accidents and improve safety performance continuously.
The primary objective of this study was ‘to develop a reliable assessment tool to measure worker engagement in safety program implementation in construction projects” and ‘to identify critical factors of successful worker engagement (WE) in safety program implementation’. The findings therefore will enable construction firms to identify gaps in worker engagement within the safety program implementation, and facilitate improvements.
This study used triangulation techniques including; theoretical model construct by a thorough literature study, components of worker engagement indicated by Grounded Theory’s techniques, verification of the theoretical model using Lawshe’s techniques, the development of a scale instrument by using DeVellis’s (1991) process supported by Clark and Watson’s (1995) and used by Du Plessis (2004), a reliability test of the developed worker engagement measurement tool by using Independent sample, t-test.
In developing the WEMT, several consultation and tests were conducted with national safety experts. Results showed that worker engagement (WE) consisted of 3 domains; cognitive (21 items), affective (26 items), and psychomotor (6 items). The content validity index of the domains according to safety experts are 0.72, 0.60, and 0.43 respectively. Additionally, the situation-related factor (31 items) and individually related factors (12 items) with respect to the content validity index were 0.56 and 0.59 respectively. A questionnaire with 53 variables in three dimensions of worker engagement and 43 variables in affecting factor was distributed to the sample group of construction workers and personnel basis either by electronic-mail or hand carried to the representative sample group of 494. Approximately fifty two percent (258/494) responded anonymously. A scale instrument was developed through the item analysis and exploratory factor analysis function of the Statistical Package for the Social Sciences (SPSS).
A worker engagement measurement tool (WEMT) comprised of 39 items in a six-factor instrument was developed. It was found that the items in these factors were highly acceptable, receiving a Cronbach alpha coefficient above 0.8.
The developed WEMT was tested in two distinct construction projects in Oil&Gas and Building projects. These test confirmed that WEMT was a reliable diagnostic tool that can discriminate worker engagement level among different projects, particularly in the Thai construction firm context.
This research also determined factors that affect worker engagement within the safety program implementation. These factors are important when guided contractors to increase worker engagement level. This study showed that suitable safety policies, a supportive management team, and individually related factors were critical and directly affects the worker engagement in safety program implementation. Workplace climate, communication and feedback, and reward and recognition were perceived by the respondents as the factors that need considerable attention to improve worker engagement.
This research is relevant because it was able to identify a reliable worker engagement measurement tool that enables projects to identify the overall level of worker engagement in safety program implementation. This tool will serve to facilitate strategic actions to improve the working situations, thereby optimizing safety program implementation for continuous safety movements. The implementation of such strategies will be a forward move towards beginning and sustaining safety program implementation for further safety performance improvement within industries, particularly in Thailand.
Key words:
Worker engagement measurement tools, worker engagement, construction project, grounded theory, scale development, affecting factors.

Project Owner’s Quality Management System – A case study of Estella Residential Development Building Construction Project
In recent years, generally, in construction industry, it is recognized that the construction sector has made a great contribution to national development as investment has been intensified in many fields such as infrastructure development, industry and public projects. However, more attention should be given to quality management because of the poor quality of some construction projects.
To enhance the quality control of construction projects, the Ministry of Construction (MOC) held a seminar on April 28, 2009 which the main concern to ensure the quality of construction projects, especially for large-scale national projects. While most projects have operated on a safe and cost-effective basis, there remain shortcomings in terms of quality at different levels due to international and external causes. Because of these reasons, the development of quality management system is most important not only for Contractors, Quality Consultants, but for the investors or developers as well.
Mr. Tran Hong Quan made a study which primary objective was to study the application of Quality Management System (QMS) of Project Owner in a construction project from design to construction phase.
Conclusions
In general, most of the requirements of quality system have been covered and presented in the existing system. However, the discovered problems that related in missing contract review, improper developed coordination and communication, lack of the process control, control of quality records and the inspection status monitoring during the course of work are the reasons that caused major problems to owner such as schedule delay and generating V.O.
In addition, it was found out that there was inconsistency in decision relating to quality on job site caused rework and schedule delay.
Obviously, besides the reason of work procedures, it would be the reasons of different quality level and quality perception. Therefore, it is necessary to conduct the internal quality audit and provide training at different position in order to gain the same level of quality perception in the project team.
Through the discussion and findings of this study, the causes and the consequences that generated by these missing processes can be summarized in the table below:
To summarize, refer to the study, in order to obtain a complete QMS, the missing requirements as previous mentioned should be added in the existing Quality Management System for fulfillment. More than that, the quality culture in organization should be formed up so that the Company can reach to the Total Quality Management.

Abstract
The report expresses the key issues in Quality Management System (QMS) that known as the critical factor for any organization wants to develop and survive in the free trade market.
This study, which refers to the theories and the standards system, has expressed the concept of quality in construction, the QMS in organization, system requirements for owner’s QMS in construction and its benefits. The study has briefed the factors that most effect to project quality studied from public reports and the key points to control project quality from the design to construction stage. The report has introduced a QMS to the property developer for the purpose of amendment to the existing QMS in order to obtain a complete QMS for better managing project quality.
The next part of this report is the case study on the Estella J.V organization that established to run and deliver the Estella Residential Development project, an international project of the Keppel Land Co. Ltd. Through this case study, the findings on the existing QMS and the application from the previous part to this existing QMS for improvement will be the foundation QMS for toward Keppel Land’ projects.

Communication Management within a Construction Project Team: A Case Study of Condominium Project in Ho Chi Minh City
The construction industry in Viet Nam especially commercial building sector, is now suffering from many problems in communication management. Some common problems are:
1. Usually skipping communication management or just approaching it shallowly due to lack of knowledge in this area.
2. Problems related to interpersonal communication (such as face-to-face meetings), intra-group communication (such as interactions between team members) or inter-group communication (such as interactions between main contractors and sub-contractors) occur very frequently at many projects. Consequently, projects communication often breaks down and projects are likely to be failed.
3. Unable to determine project stakeholders’ needs for information, unable to determine communication channels in projects, insufficient interaction between project management and team members or between main contractor and sub-contractors or within team members, inappropriate communication media, etc.
4. Timing of distributing information, correct information to correct stake holders, wasting a large amount of time and resources for unnecessary meetings, etc.
5. Unable to combine verbal communication and non-verbal communication in order to achieve targets.
6. Abusive using of bad emotional methods during interaction between project management and team members such as fear and threats, aversive stimulation, etc.
It is important to understand the nature of the problems and to find ways to solve them in order to be able to develop an effective communication management system in construction projects. Mr. Nguyen Canh Toan made a study which objectives were to: (1) investigate the communication interactions within construction project team so that communication problems causing project interruption can be identified; and (2) propose recommendations on how to improve communication management within construction project team.
Conclusions
The important role of communication management within construction project team was clarified. During construction phase, interactions within the main contractor’s team members and between the main contractor and subcontractors were analyzed. Communication problems were classified into three categories, i.e. coordination, information distribution and interpersonal communication. The problems relating to coordination category occurred most in the project which caused project delay. In order to solve these problems, proposed solutions based on theoretical and recommended practices including guidance from the PMI’s PMBOK guide, one of the world’s most prestigious guides to the project management, were presented. Besides, some useful tools were considered and suggested to use as aids for the project managers to improve communication management in the project.
However, there are some limitations in this study. First, the relationships between communication problems and types of information in action have not been graded in order to figure out which one is the biggest factor that causes communication interruption; or the applicability of the proposed solutions for those problems.
Recommendations
In order to avoid similar communication problems, recommendations are given below:
1. Project Manager shall prepare project management plan including communication plan in the beginning of the project.
2. Strictly following the communication plan. Incentives shall be provided to encourage everybody to carry it out properly, and also treatments or even punishments for bad behaviours.
3. Document controller position must be stable as much as possible in order to ensure that the information distribution process is in order.
4. In case of ISO certified company, Project Manager should give feedback to the company’s Quality Manager to add in personality test forms together with Job Application Assessment Procedures forms. That will save Project Manager’s time whenever there is new job applicant coming to job site for interviewing.
5. Using new information-conveying methods such as: web-based data distribution, e-meeting, etc. in order for easy document control and timing of document distribution.
6. Organizing trainings for the team members in order for them to know how to use both verbal and non-verbal communication effectively.
7. Outside activities such as playing football, parties, etc. are recommended to improve relationships among team members and between the main contractor and subcontractors.

Abstract
Communication management is one of the nine knowledge areas that can be found in the Project Management Institute’s A guide to the Project Management Body of Knowledge. This is a really tough challenge and time-consuming task to any project manager. Despite the fact that ineffective communication management will result in project interruption or even failure, there are not many project managers or site managers in Vietnamese contractors being aware of its importance. This final project report focuses on construction project communication management between the main contractor and subcontractors as inter-group communication and within the main contractor team members as intra-group communication. By reviewing many researches and studies of many authors on this field, knowledge as regards communication management within team and with external party such as will be explored step by step. Through a case study of condominium project in Ho Chi Minh City, communication problems which cause project interruption will be investigated and analyzed. Some proposed solutions which are based on the reviewed knowledge will be discussed in order to help project managers improve communication in the project.

Delays in Construction Projects in Vietnam: A Case Study of Last Section of National Highway No. 51
In recent years, Vietnam’s economy has been grown rapidly and becoming one of the countries with highest growth rate in the world. As a consequence, construction industry grew rapidly while project management could not meet requirement of construction industry.
There is a fact in Vietnam that delay happens in almost all construction projects; especially in projects that are state-funded and contractors are domestic. Projects which were carried out by international contractors are less likely to suffer delay. Responsibility for delay was not clearly defined. Therefore, whenever delay happens, no one was blamed. Because of this, the owner often give contractors extended time to finish the project without any penalty. In very few cases, contractors were given more time but had to pay a penalty.
However, in general, delay and cost overrun are the biggest problems in bombing construction field in Vietnam. Mr. Truong Quang Dien made a study which focused on the factors affecting the construction stage construction projects in Vietnam. The objectives of his study were: (1) recognizing frequency causes of delay; (2) defining effects of delay in progress of projects; and (3) solutions to delay problem and how to deal with delay when it happens
Conclusion
The delay in construction projects in Vietnam which was discussed in this paper was focused on frequency, severity and importance of the causes of delay, effects of delay and how the delay was solved.
The frequency and severity causes of delay were identified through previous research, present issues, and widespread contributions of construction field in Vietnam. The construction participants accorded inexact time, slow site clearance, slow government’s permits, poor site management and supervision, financial difficulties, incompetence subcontractor, and unforeseen factors.
Slow acquisition was frequent cause of delay in almost construction projects in Vietnam, which affected the whole schedule of the project. In the Owner’s point of view, the causes of delay were related to the responsibilities of both contractor and subcontractor.
This paper showed that owners and consultants realized that contract awarding to the lowest bidder was frequent causes of delay, meanwhile contractors considered severe causes of delay were related to owners and consultants like unclear responsibilities, slow-making decision from owners about some changed works during construction. One common cause of delay was Change Order initiated by owner during construction. Besides there were many causes between two parties, such as progress payment delay from Owner, ineffective scheduling, poor site management and supervision, shortage of labors and difficulties in financing from contractor.
However, all parties agreed that the following causes rarely occurred and were less important: changes in government regulations, restrictions at site, effect of social and cultural factors.
In general, there were certain interrelationships among the problems. The top-ranked problems including occurrence were grouped under some major factors: site related issues, incompetent designers and contractors, poor estimation, poor site management and supervision, poor contract management, price fluctuations, and improper techniques. It was noted that the findings confirmed previous studies that most of problems in construction projects were related to human behavior and management problems, and not technical in nature.
In order to mitigate delays in construction industry in Vietnam, all required training for engineer for their competency in term of technical, and safety was required. Therefore, there were no more gaps in planning, managing and organizing and safety. Project feasibility study must receive a serious attention and must be done carefully especially on government funded projects. In addition, contract management work should be the focused. Although Vietnamese government has regulated many decrees or circulars ruled on this work and published contract template, it always needs experienced parties to do contract work and suit template to real project conditions.
From above causes, the effects of delay were cost overrun and party’s damages. Third parties were people who would get profit from operating or using the project.
Recommendations
To reduce delays, all parties should consider following important factors:
1. Separate site clearance (acquisition) work from construction work and it must be finished before estimating cost and schedule for construction phrase and bidding work.
2. Make clear responsibilities among parties in the contract document and use CPM (Critical Path Management) to manage schedule during construction.
3. Make Planning and scheduling: they are continuing processes during construction and match with the resources and time to develop the work to avoid cost overrun and disputes.
Besides the three most above mentioned causes, the following points can be recommended by all parties in order to minimize and control delays in construction projects.
• For the Owners
1. Progress payment should be made on time otherwise it impairs the contractor’s ability to finance the work.
2. Change orders should be minimized as much as practical during construction to avoid delays.
3. Avoid delay in reviewing and approving of design documents than the anticipated.
4. Check for all resources and capabilities, before awarding the contract to the lowest bidder.
• For the Contractors
1. Shortage and low productivity of labor: enough number of labors should be assigned and be motivated to improve productivity.
2. Financial and cash flow problems: contractor should manage his financial resources, plan cash flow by utilizing progress payment and ensure financial during construction.
3. Site management and supervision: administrative and technical state should be assigned as soon as project is awarded to make arrangements to achieve completion within specified time with the required quality and estimated cost.
4. Subcontractors and suppliers: selecting subcontractors and suppliers with competence and experience, and also with enough financial resources. Contractors should not select subcontractors and suppliers with low bidding price.
5. Planning and scheduling: they are continuing processes during construction and match with the resources and time to develop the work to avoid cost overrun and disputes.
• For the Consultants
Reviewing and approving design documents: any delay caused by the consultant engineer in checking, reviewing and approving the design submittals prior to construction phase could delay the progress of the work.
Inflexibility: Consultants should be flexible in evaluating contractor works. Compromising between the cost and high quality should be considered.

Abstract
In construction project management, delay means the finish date of the project is beyond the date stated in contract. When delay happens, cost often increases because of inflation or other factors. Most construction projects in developing countries, including Vietnam, are suffering two problems: delay and cost overrun.
For the owner, delay means cost more for capital and loss of income from operating the outcome of the project. For constructors, delay means cost more for construction work because spending on materials, labors and vehicles will increase.
Completing project on time and within in-plan cost is an indicator of efficiency in project management. However, construction progress is often changed and affected by unforeseen factors such as: contractor-related problems: Poor site management and supervision, Financial difficulties, Incompetence subcontractors; owner-related problems, design-related and slow site clearance, etc.
This report will try to find out which reasons are main reasons for delay in Vietnam based on previous researches and personal experience of author. Also, solutions for this problem will be mentioned in chapter IV as a suggestion of author.
There is a fact in Vietnam that delay happens in almost all construction projects; especially in projects that are state-funded and contractors are domestic. Projects which were carried out by international contractors are less likely to suffer delay. Responsibility for delay was not clearly defined. Therefore, whenever delay happens, no one was blamed.

Abstract
In construction project management, delay means the finish date of the project is beyond the date stated in contract. When delay happens, cost often increases because of inflation or other factors. Most construction projects in developing countries, including Vietnam, are suffering two problems: delay and cost overrun.
For the owner, delay means cost more for capital and loss of income from operating the outcome of the project. For constructors, delay means cost more for construction work because spending on materials, labors and vehicles will increase.
Completing project on time and within in-plan cost is an indicator of efficiency in project management. However, construction progress is often changed and affected by unforeseen factors such as: contractor-related problems: Poor site management and supervision, Financial difficulties, Incompetence subcontractors; owner-related problems, design-related and slow site clearance, etc.
This report will try to find out which reasons are main reasons for delay in Vietnam based on previous researches and personal experience of author. Also, solutions for this problem will be mentioned in chapter IV as a suggestion of author.
