Along with the growth of economy, the telecommunication industry also was developed to satisfy the demands for using the internet, voice, fax, data, multimedia, and entertainment of individual, community and company.
The erection for self support steel towers for telecommunication industry is one of the difficult infrastructures in Vietnam. Two main problems of telecom projects are:
1. Difficult geographical and topography conditions to access the construction sites to deliver materials.
2. Difficulties of fabricating the steel on site
These problems are different for each project since every project has particular geography and topography, and problems are not only happen for purchasing and managing materials but also in transporting materials to site.
Nguyen Huu Phuc made a case study which main objective is to find out An Effective Project Materials Management for erecting of self-support steel towers for telecom based on real conditions in Vietnam.
Conclusion
The project material management is major function in construction to assure quality, cost and schedule of project. With good way for project material management, the contractors can reduce project cost and make more profit from project.
An effective material management is not only good techniques for planning, monitoring and control of processes, materials and products at the site, office and factory but also is good function to avoid the most frequently occurring problem and the most frequently occurring place or step of problems.
The planning is the first step to do the project material management. It is a blueprint to set up sound basis for project life cycle. Due to data of planning, the activities for processes behind the planning were determined. Thus, planning is major figures to get the success of project. If the actual work does not meet the requirement of the planning for schedule or budget, the project will fail.
The appropriate organization in construction for each project and for the success depends on personal skills of members and their geographical location in the department or on the site. The skills of members in organization are very important to do their tasks.
One more thing, the purchasing in the project must connect between planning for requirement and ordering of demand for material and equipment on the site. The purchasing ensures that materials and equipment are supplied with competitive price, on schedule work and good quality. In purchasing, the relationship with suppliers and performance of suppliers are keys to have the effective material management
For the transportation, the company can save the cost through out the negotiated agreements or special agreement such as special scope of transportation work or special duty of transporters or special for handling and packaging. In addition, the survey for conditions of transportation also has the main role to eliminate the risk in the traffic.
The activities for monitoring and controlling of estimation, ordering, checking of the performance and surplus on the site are supported by requirement planning and actual work on the site. It affects project productivity and other factors in the project. Solving procedures for improving the site monitoring and controlling are requirements that the project manager must be consider.
According to the contract, the quality always is the most important provision. It involves all material management cycle and affects all project phase. Accordingly, quality assurance and control related with all responsible of contractor, suppliers and owner.
Recommendations
In order to improve actions and processes for project management in the future, from this study, some proposals are given to correct activities and reduce cost for materials in construction such as:
A plan for short interval planning, monthly planning and project planning should be written down and communicated to the related people. In planning for material management, the material that it has the high value, when comparison with project cost, must be cared first. The information for planning must be more detail and complying with the scope. Beside, historical data and job review should be collected to help us to learn from past successes and failure. It is a tool to plan with accurate data to implement the work on site.
Top leader must support the organization for project material management and have the members with appropriate skill based on the scope of work. The individual must know his responsibility and his role in the organization.
The evaluated suppliers must be checked carefully not only with their history but also their performance in the present. The price, quantity, quality, delivery time, the rights and penalties must be defined clearly in the contract with suppliers.
The materials for the project must be tested to meet the standard on the sources before using on the site. When the site manager receives these materials, they must check against to ensure the quality of material that they use for work. In addition, the procedure work must be inspected and review to ensure the quality of products.
The communication for the organization and other parties must set up with appropriate ways to connect all related people. With good communication processes, the contacts of related people will be come easily to avoid the refusing actions.
For further study, the study should research deeply on material cost variance and behaviors of workers when they use the materials on the site to get more effective material management.

Safety and Quality Management for Construction Based on Construction Regulation and Contract in Vietnam
For the last 20 years, the political innovation of the Vietnam leaders has made the face of the whole country be changed. With the new policies of government, all of sectors of Vietnam economy have been developing strongly since beginning of decade 1990 and construction industrial sector may not be out of that movement, it has been booming to meet the requirements of economical development. In fact, construction industry achieved complete success in executing its mission.
However, in other side of success, the weakness has appeared: many accidents happened in recent years, hundreds construction workers died and injury, many construction parts and elements collapse. These accidents happened in many projects with different owners, contractors and consultants. Number of dead and injury people is very big, many times comparing 10 years ago.
The fatal accidents still happen everywhere in the whole country and many times more than decades before. Moreover, the happened accidents are not only influence to workers and projects but also to money and time. It normally takes much money to compensate the loss of workers and to repair the damages of the project and many other expenses. Besides, is takes much time-consuming for accident investigation and designing and repairing and sometime for legal questions.
Some people think they are just bad lucky of those projects due to the rate between the projects in which accident happened and total projects each year is not too high. That is worth for developing economy. Evenly they said that accidents are unavoidable. Is that true? Should we have the right to feel contempt the workers’ life when they serve for construction projects?
To have a better situation, with the supporting from studying of AIT dossier I hope that this material will give a hand to improve it analyzing every aspect of the problem in detail and then putting forward proper recommendation.
Mr. Hoang Don Dung made a study aimed to : (1) analyze the reasons of the recent constructing accidents in Vietnam which are related with the quality of temporary structure; (2) apply the regulation of Vietnam government and FIDIC contract to study these accidents; and (3) give out some recommendations to improve the safety and quality of temporary support structure in construction process.
His Conclusion
Studying occupational accidents happened in the past, we can recognize that there were two kinds of them: predictable or unpredictable. But the damages of these accidents were taken by human. A predictable occupational accident means avoidable if we do the right work. Most accidents of temporary construction structure in the past are predictable and avoidable but they have happened because a behavior of construction employees: subjective.
Many people at site often think that every temporary structure is just serving for executing a super-structure, it is not worth for long time. The executing weight loading on temporary structure is short-term load, too. They suppose that owners or customers won’t check it closely and in detail like other parts of project. In fact, some kinds of loading capacity may load on superstructure but not on temporary structure such as loads defined by probability, loads following seasons, earthquake, etc. This makes ideas of disregarding the temporary structure systems.
Combination with the conclusion in the end of Chapter 3 and my above opinion, I have a general conclusion for all happened occupational accidents caused by the quality of temporary structures at site:
In many projects, temporary structures have not been considering as superstructure in processes of designing and executing.
That means before implementation the temporary structure at site, it must be designed in detail attending the applied standard and codes. The design drawings and specification must be verified and accepted carefully by the Engineer/Supervisor as defined by Fidic terms or Vietnam Decree 209 to the superstructure.
Before implementation the temporary structure at site, its materials must be tested attending the applied standard and codes. Contractor may use old material but loading capacity must be ensured. Besides, using materials for the temporary structure must obey specification.
Contractor’s technical staff and owner’s supervisor must supervise and accept temporary structures carefully to achieve technical requirements defined by approved design and specification.
Recommendations
To solve the problems, the support of authority is indispensable. Government policies should have to regulate besides the regulations that were defined in Decree 209 (or the Fidic conditions of contract if applied) as follows:
a. Every temporary structure must be behaved as superstructure in designing and executing process.
b. Contractor’s employees have to be trained appropriately. They have to have proper profession certificates.
Abstract
Years by years, the persons who do their routine work at construction site still try to devote themselves to their jobs. Now and then there is information of a construction accident happened some where, they hear information and feel sorry for their coworkers. Then they can forget it at once because they think simply that accident was not their case; it does not relate to them.
Is that true? Don’t they relate completely and absolutely to any occupational accident though it happens out of their construction site? The answer is no because each of them is playing a roll in construction sector. Each person has his obligation of occupation. Somehow, by his opinions or activities he can help either to prevent accidents or reduce damage. He may not keep it for himself. Therefore those opinions must be written down.
This report writes about occupational accidents happened in Vietnam construction site in several recent years. The accidents happened by poor-quality and un-safety of the different temporary structure systems at the different site but basically the causation is human. They did not put all their consideration to the temporary structure because it’s non-permanent. In fact, they did design, manage, execute and check the temporary structure carelessly.
The author hopes that this report will give a more opinion to persons who do their routine work at construction site related to temporary structure systems. They will play very well their rolls at site as defined by government regulations and/or terms of Fidic contract.
However, in other side of success, the weakness has appeared: many accidents happened in recent years, hundreds construction workers died and injury, many construction parts and elements collapse.

Analyzing the Logistic Process for Pre Engineering Building (P.E.B) Construction
In the industrial construction projects, Erection is the last important stage of P.E.B product life cycle which deals with installation P.E.B products. This stage needs the fulfillment of previous stages such as design, fabrication, shipping to job sites. However, in the real erection job sites, especially the job sites in Vietnam, there are lots of problems happened in these stages that make erection stage being delay and can not be completed as expected.
As observation from industrial construction projects in Vietnam, the schedule delay currently becomes very popular. Among the causes of this issue, problems have occurred as a result of poor logistics supply chain network management such as:
1. Delay in delivery time of material , equipment , labor compare to plan
2. Materials were delivered inadequately.
3. Materials were delivered wrongly in type as well as differently from specification.
4. Raw materials for production main structures can not be provided enough for production.
5. Plan and schedule ineffectively that leads to inefficiency in arrangement of equipments and labor.
Mr. Le Khac Bao made a study on construction logistic for Pre Engineering Building construction where the integration of all process of designing, detailing, procurement, fabrication and delivery of finished products to job site for the accomplishment of erection work.
The objectives of his case study were to: (1) provide further insights into the arising problems from construction logistic process for erection job sites of P.E.B company as a real case study; and (2) develop specific recommendations for future improvements.
Conclusion
The results revealed that many causes come from the processes in Plant such as fabrication, purchasing or logistic deliveries, than other stages such as job site and office , and stage should be paid more effort to improve than the other ones . The office stage of engineering department could be seen as the best, but there are still more issues need to be solved.
Finally, no matter what the stage issues were in, all issues should be solved properly in order to implement the current logistic process for propose of success of P.E.B projects.
With objectives of continuous improvement, the implement of these improvements might lead to the needs of new improvements; the new similar studies will be made for implement them.
Recommendation
With the objectives of sustainable development of a new construction area - Steel structure in Vietnamese market, these recommendations should be carefully considered to maintain and improve for final result is the increasing of trade mark reputation and long term relation ship with the customers.
As above analysis, almost of issues of construction logistic process for erection are related closely with human factor, therefore , if something need to be recommended , I would like to recommend to improve which related to human factors. Hereafters are the characters might need to consider to success the purpose of improvement construction logistic for P.E.B projects:
1. Clear policy —Top management should take a leader role in commitment toward improvement. There should be clear policy from top management to support the implement process.
2. The term ‘Just-In-Time’ (JIT) — used for instance to describe the delivery of materials to a construction job site, suggests that materials will be brought to their location for final installation and be installed immediately upon arrival without incurring any delay due to storage in a lay down or staging area. The ultimate objective of JIT production is to supply the right materials at the right time and in the right amount at every step in the process.
3. Being responsible — Each people who involved into construction logistic process should be responsible to what they were assigned is to contribute their part to the success.
4. Honest — always be honest in every situation is the key to success in developing construction logistic.
5. Clear in scope of work — always make clear every thing to Customer Subcontractors as well as between internal departments to avoid unexpected conflict later.
6. By establishing a subcontractor database — we are able to know the information about subcontractors. It helps to have better understanding about sub contractors’ performance.
7. Flexible and Creation — apply the existing value and properties to increase maximum their effectiveness.
8. Looking ahead for sustainable development — doing in professional way for sustainability in development.

New Urban Zone Infrastructure Development Project Risks
Risk and uncertainties comes from various sources. In new residential zone project, risk impact schedule of project implement, project quality, project finance and time of customers and government hand-over.
In recent years, many real estate companies have been establishing and many New Residential Zone Projects were established. Along Nguyen Van Linh highway and in HCMC many of new residential zone Infrastructure development projects have been being delayed and project cost over run due to many reason such as land compensation issues, lack of social agreement, insufficient of capital for buying the land, late in permitted from authority especially in master plan and architectural city design, poor in design and construction, water treat and environment issue and so on. In those projects managers could not deal with the risks and uncertainties which they met in project implementation process.
Project risk is an uncertain event or condition that, if it occurs, has a positive or a negative effect on at least one project objective, such as time, cost, scope, or quality (PMI, 2004). Additionally, Ahuja and Nandakumar (1985) demonstrated that a delay in project completion can cause a cost escalation at least equal to the sum of inflation, overhead cost, and addition interest cost for the period.
Furthermore, there is another actuality to be noted that even successful project have not been able to transfer their best performance and knowledge in the effectively and efficiently way to other projects. Consequently, realizing the list of factors contributing to reducing project time and cost is lacking.
Mr. Hoang Ngoc Anh made a study to find out the risks or uncertainties in new urban infrastructure development project in general and in particular An Phu Tay residential zone project of SADECO and to conduct a risk management to response to them. The objectives of his study were: (1) identifying the risk factors in the infrastructure development in new residential area project; and (2) propose strategies to effectively avoid or mitigate the negative impacts of major risks.
Conclusions
Risks and uncertainties come from various sources. Risk can not be eliminated, but can be minimized, transferred or retained. There are some ways of risk dealing such as transfers the risk to another party, avoiding the risk, reducing the negative effect of the risk, and accepting some or all of the consequences of a particular risk.
The process of taking a construction project in general as well as Development infrastructure for new residential project in particular from initial to completion and transfer is complex. Moreover, there are many organizations and partners who involved a construction project, especial in New urban zone Infrastructure Development project. These organizations involve land owners, client, designers, contractors and subcontractors, consultants, material suppliers, power and water suppliers, customers, public facility agencies, authorities and so on.
In new urban zone development project, risk impact schedule of project implement, project quality, project finance and time of customers and government hand-over. In order to deal with risks, it is essential to establish a strategy that can effectively and efficiently response. Thus, this project study tried to identify major risks and conducted a risk management study for New urban zone Infrastructure Development project. Besides it, the author proposed appropriate strategies to mitigate these major risks.
Identify major risks
Characters of New Urban Development Project as follow:
1. Land area of the project has to big enough over 20ha following Decree 02/ND-CP issued by VN Government. Thus, there are a lot of land owners at area that will be construction site.
2. There are various specialized design consultant organizations on engineering infrastructure joining in design.
3. There are many contractors different from specialized technology, constructing in the same site on surface and underground at the same time.
4. Running time for the project implementation is often long.
5. After engineering infrastructure construction completed, developers have to transfer them to Public Facility Agencies and Government for management.
These above characters related with risks and uncertainties occurring in the project. It is essential to understand project’s characters so that we can deal with risks occurring in the project.
According to data from An Phu Tay residential zone project, statistics of new urban zone development projects and the similar projects in HCMC and throughout VN recent, many major risks were identified and found out that the top three risks occurring in this project as follow:
1. Late in design approval by the authorities,
2. Late in site clearance in construction process, and
3. Construction cost increase because of delay and inflation.
Recommendations
The findings of this study are expected to contribute to identify major risks and more effective risk management process in project. This study proposes some recommendation:
1. When planning the Feasibility Study, it is necessary to study carefully on financial capacity of developers, size and implement time of the project, as well as inflation predictions.
2. Specialists of project planning have to master on engineering, get much working experience. They are to estimate scope of works in order to take project running time reasonably.
3. Feasibility Study Evaluation Authority needs to consider the reality to access project’s feasibility; especially, site clearance issue.
4. It is necessary to define clearly capital flow, option for partitioning investment and business in Feasibility Study. Besides, it is suggested to submit ideas to the Government on construction investment, engineering infrastructure constructions lying outside of fences of the project, connection point and so on.
5. To site clearance, developers need to have planning and schedule suitable to construction procedure of the project.
6. Clients must make timely and quickly decisions in negotiating costs with land owners and need to have good relationship with local authorities to get supports in compensation on site clearance. Beside, it is necessary to make arrangements for resettlement area or temporary residence zone for households living at construction region, so that can hand over site area sufficiently to contractor.
7. Choose experienced design companies; project leader of design team has experienced in design the same construction items.
8. Design contract has to be stipulated conditions on reward and punishment; especially, responsibilities on submission and approval at Public Facility Agencies.
9. Designers and consultants have to always update regulations and standards of Government and Public Facility Agency, and responsible for their acceptance and accept of contract based on their ability only.
10. Design costs are low following Vietnam Government’s regulation; therefore, developers should not recommend designers down expenses.
11. EPC contract should be applied on construction items transferred to Public Facility Agencies. EPC contracts will be signed with high-capable companies dealing with transferring products to Public Facility Agencies.
12. As planning construction schedule, it is necessary to study carefully overlapped building items; from then, take measures fitted with surface and underground engineering items building in the same lay-out.
13. Clients should know that high commitment of all people involved in all processes of project is very important to solve complex conflicts and problems occurring in project. In addition, developers have to set up a Project Management Unit (PMU) that owns a team of experienced and capable experts in order to manage and run the project. The PMU must have authority to make decisions quickly under delegation of developers.
14. Clients should make favorable conditions for staffs improving their knowledge, skills and to update new knowledge. On the other hand, to attract capable and experienced experts and engineers, developers should pay high salaries for them.
15. Building construction progress and program must be planned strictly. It should be taken care of items be able to overlapped. For example, as road contractors finish road foundation, contractors on water, electricity are to install uptime underground systems; avoiding that contractors on underground works excavate the roads accomplished to install underground systems; then, reconstruct them as happened to some projects in Vietnam. Besides, it is avoided damages for road contractors as stopping construction to wait for operation of contractors on underground systems.

Abstract
Risks and uncertainties come from various sources. In New Urban Zone Infrastructure Development Project, risks related participants involving the project, impacted schedule of project implement, project quality, project finance and time of customers and government hand-over.
Risk management is an important part of the decision-making process of all construction companies. Risk and uncertainty can potentially have damaging consequences for some construction projects. Risk can be affect productivity, performance, quality, and the budget of the project. Risk can not be eliminated, but can be minimised, transferred or retained
Risk management is a systematic approach to managing unexpected related to a threat, through a sequence of human activities including: Risk identification, Risk classification, Risk analysis, Risk response, Risk evaluation.
In the organization, there are some ways of risk dealing such as transfers the risk to another party, avoiding the risk, reducing the negative effect of the risk, and accepting some or all of the consequences of a particular risk.
In recent years, many real estate companies have been establishing and many New Residential Zone Projects were established.

In new urban zone development project, risk impact schedule of project implement, project quality, project finance and time of customers and government hand-over. In order to deal with risks, it is essential to establish a strategy that can effectively and efficiently response. Thus, this project study tried to identify major risks and conducted a risk management study for New urban zone Infrastructure Development project. Besides it, the author proposed appropriate strategies to mitigate these major risks.
Identify major risks
Characters of New Urban Development Project as follow:
1. Land area of the project has to big enough over 20ha following Decree 02/ND-CP issued by VN Government. Thus, there are a lot of land owners at area that will be construction site.
2. There are various specialized design consultant organizations on engineering infrastructure joining in design.
3. There are many contractors different from specialized technology, constructing in the same site on surface and underground at the same time.
4. Running time for the project implementation is often long.
5. After engineering infrastructure construction completed, developers have to transfer them to Public Facility Agencies and Government for management.
These above characters related with risks and uncertainties occurring in the project. It is essential to understand project’s characters so that we can deal with risks occurring in the project.
According to data from An Phu Tay residential zone project, statistics of new urban zone development projects and the similar projects in HCMC and throughout VN recent, many major risks were identified and found out that the top three risks occurring in this project as follow:
1. Late in design approval by the authorities,
2. Late in site clearance in construction process, and
3. Construction cost increase because of delay and inflation.
Recommendations
The findings of this study are expected to contribute to identify major risks and more effective risk management process in project. This study proposes some recommendation:
1. When planning the Feasibility Study, it is necessary to study carefully on financial capacity of developers, size and implement time of the project, as well as inflation predictions.
2. Specialists of project planning have to master on engineering, get much working experience. They are to estimate scope of works in order to take project running time reasonably.
3. Feasibility Study Evaluation Authority needs to consider the reality to access project’s feasibility; especially, site clearance issue.
4. It is necessary to define clearly capital flow, option for partitioning investment and business in Feasibility Study. Besides, it is suggested to submit ideas to the Government on construction investment, engineering infrastructure constructions lying outside of fences of the project, connection point and so on.
5. To site clearance, developers need to have planning and schedule suitable to construction procedure of the project.
6. Clients must make timely and quickly decisions in negotiating costs with land owners and need to have good relationship with local authorities to get supports in compensation on site clearance. Beside, it is necessary to make arrangements for resettlement area or temporary residence zone for households living at construction region, so that can hand over site area sufficiently to contractor.
7. Choose experienced design companies; project leader of design team has experienced in design the same construction items.
8. Design contract has to be stipulated conditions on reward and punishment; especially, responsibilities on submission and approval at Public Facility Agencies.
9. Designers and consultants have to always update regulations and standards of Government and Public Facility Agency, and responsible for their acceptance and accept of contract based on their ability only.
10. Design costs are low following Vietnam Government’s regulation; therefore, developers should not recommend designers down expenses.
11. EPC contract should be applied on construction items transferred to Public Facility Agencies. EPC contracts will be signed with high-capable companies dealing with transferring products to Public Facility Agencies.
12. As planning construction schedule, it is necessary to study carefully overlapped building items; from then, take measures fitted with surface and underground engineering items building in the same lay-out.
13. Clients should know that high commitment of all people involved in all processes of project is very important to solve complex conflicts and problems occurring in project. In addition, developers have to set up a Project Management Unit (PMU) that owns a team of experienced and capable experts in order to manage and run the project. The PMU must have authority to make decisions quickly under delegation of developers.
14. Clients should make favorable conditions for staffs improving their knowledge, skills and to update new knowledge. On the other hand, to attract capable and experienced experts and engineers, developers should pay high salaries for them.
15. Building construction progress and program must be planned strictly. It should be taken care of items be able to overlapped. For example, as road contractors finish road foundation, contractors on water, electricity are to install uptime underground systems; avoiding that contractors on underground works excavate the roads accomplished to install underground systems; then, reconstruct them as happened to some projects in Vietnam. Besides, it is avoided damages for road contractors as stopping construction to wait for operation of contractors on underground systems.

Abstract
Risks and uncertainties come from various sources. In New Urban Zone Infrastructure Development Project, risks related participants involving the project, impacted schedule of project implement, project quality, project finance and time of customers and government hand-over.
Risk management is an important part of the decision-making process of all construction companies. Risk and uncertainty can potentially have damaging consequences for some construction projects. Risk can be affect productivity, performance, quality, and the budget of the project. Risk can not be eliminated, but can be minimised, transferred or retained
Risk management is a systematic approach to managing unexpected related to a threat, through a sequence of human activities including: Risk identification, Risk classification, Risk analysis, Risk response, Risk evaluation.
In the organization, there are some ways of risk dealing such as transfers the risk to another party, avoiding the risk, reducing the negative effect of the risk, and accepting some or all of the consequences of a particular risk.

Safety Management In Steel Structure Fabrication And Erection
Safety in Construction is considered the success of project. In developed countries, safety is the always concern and closely controlled whereas in developing countries, in order to reduce expenses, this work seems unconcerned in many projects which results in many accidents that really affect the project seriously.
Safety in the fabrication and erection steel structure has always been a major problem. Steel construction is found to be one of the most dangerous on safety and health criteria, particularly in developing countries with a lot of accidents. Though much improvement in steel construction safety has been achieved, the steel structure fabrication and erection still continues to lag behind most other activities with regard to safety.
In Vietnam steel construction industry, safety accident rate is very high. This is due a lot of causes such as lack of workers’ awareness on safety, lack of safety training for workers to implement in the project, lack of PPE for workers, substandard construction equipments, lack of safety policy, safety plan, and so on.
The company-TT Construction has set the safety management system and it has been implemented in the GREEN STAR projects. In construction stage, some minor accidents and one major accident happened.
Mr. Bui Giang Nam wanted to assess the project safety plan and the safety management system of the project so we have information and experience for other projects in analyzing accidents happened in his company. His study focused on the specific objectives as follows:
1. Analyze the typical accident in the steel structure project;
2. Assess the project safety plan and safety management system; and
3. Propose recommendations for improvements safety management system
Conclusion
Most of the construction companies in Vietnam emphasize more on quality and productivity in terms of output. However, safety is one of the key measurements of good productivity which the people seldom realize. Through the analyzing of some accidents happened on the Green Start Project, the Safety plan was lack of some articles . The characteristic of ironworks are different and more dangerous from other works in construction . TT company should establish some procedures on the safety plan in future project
Following the Accident/Incident theory: Management of TT Company does not establish a comprehensive safety policy. Responsibility and authority with regard to safety are not clearly defined. Safety procedures such as measurement, inspection, correction, and investigation are ignored or given insufficient attention. Employees do not receive proper orientation. Employees are not given sufficient safety training or persons were trained on hazards and safe work procedures but not follow when performing the task.
Some problems of the Safety management system of TT Company :
- Unadequate commitment of top management
- Lack of Human resources for SMS
- Lack of Incentive and Reward
There are some key elements that can be the examples for other companies especially construction companies in Vietnam has written job description for each safety personnel on company and on site, provide safety training and record keeping which can be used as the document for safety measurement. Furthermore, there are written rules and regulations for each site personnel, safety committees to ensure the deployment of the safety plan, policy and programs.
Recommendation
TT Company should has some adjustments with their Safety management system such as:
1. Top manager should has commitment to supporting OH&S
2. Top manager commit to support OH&S. Establishing a Safety Management Organization with defined responsibilities of management staff as overall co-ordination and implementation of the Policy and the Safety Management System in the project
Besides financial supporting adequacy, top management staff have to realize their roles to play in safety. They should appreciate the communication between them and the frontline workers, which could impress the workers and thus improve the workers’ risk-taking mindset.
- Ensure that human resource is adequate for implementing and maintaining Safety Management System
TT company should recruit safety managers and safety supervisors for other projects in the future. The supervisor should provide the means to ensure that all workers are adequately instructed and trained , ensure that workers doing dangerous work have adequate training, experience and other qualities to carry out the work safely.
- Establish the incentive programme in order to motivate workers doing their jobs safely
• Behaviors required to achieve a safety reward should be specified and perceived as achievable by participants
• Everyone who meets behavioral criteria should be rewarded
• It is better for many participants to receive small rewards than for one person to receive a large reward
• Rewards should be displayable and represent safety achievement (I.e., coffee mugs, t-shirts, hats or jackets with a safety message)
• Contests should not reward one group at the expense of others
• Groups should not be penalized (lose rewards) for failure by individuals
• Progress towards achieving a safety reward should be systematically monitored and publicly posted
TT Company should also conducts Job Hazard Analysis which includes hazard identification and risk assessment to anticipate the hazard on site, the harshness of the consequences and the probability to happen. Moreover, TT company should also implement PPE program, accident investigation to reduce the probability of re-happening, emergency preparedness, safety promotion to induce the workers to work safely, evaluation of the subcontractor, health and welfare, security control, equipment inspection and waste material movement plan.
There are some key provisions of steel fabrication and erection when setting procedures for ironworks like: Cold stress; Heat stress; Lead exposure; Site Layout and Construction Sequence; Site-Specific Erection Plan; Hoisting and Rigging; Structural Steel Assembly; Column Anchorage; Beams and Columns; Open-Web Steel Joists; Systems-Engineered Metal Buildings; Falling Object Protection; and Training
Besides establishing appropriate safety procedures related with steel fabrication and erection Safety Policies of TT company should include:
1. The commitment of the top management to support OH&S. Ensure adequate supporting for implementing, maintaining and improving the SMS. To give Safety to be the highest priority and to inject safety consideration into every aspect of the Project
2. To recognize employees are the most important assets and to enrich their safety awareness by ways of Interactive Safety Training, Safety Promotion, Safety Meeting and Counseling.
3. To regular review, not least than once per year, the Policy, the Safety Management System for its efficiency and effectiveness by way of Management Inspection and Review and Safety Audit conducted by Senior Management Staff,
4. To maintain a high standard of safety performance and to the satisfaction of the Client at all time and also a progressively improvement in the standard achieved by continue monitoring and regular review.

Abstract
Safety in the fabrication and erection steel structure has always been a major issue. Wherever reliable records are available, steel construction is found to be one of the most dangerous on safety and health criteria, particularly in developing countries. Though much improvement in steel construction safety has been achieved, the erection steel structure still continues to lag behind most other activities with regard to safety. In developing countries, safety in fabrication and erection rules usually do not exist; if any exist, the regulatory authority is usually very weak in implementing such rules effectively. Further, work hazards at the construction workplace are either not perceived at all, or perceived to be less dangerous than what they actually are.
Most steel companies can give many good reasons why they want to implement management safety system. A well-designed safety management system can help to reduce injuries and illnesses and prevent risks and hazards. In addition, a good management system can increase efficiency, improve productivity and quality of services.
Through the assessment of some typical accident cases in steel construction of one project in LONG AN- The Green Star Factory, I want to assess the project safety plan and the safety management system of TT Company. Furthermore, I want to improve the existing safety management system of the company in order to prevent the accident happening in the future.
