Abstract

             

In the recent years, in most construction projects, particularly building projects prefer to hire subcontractors. Consequently main contractor need to develop management system standard in order to manage subcontractor rather than they will undertake construction work by themselves. As a result, main contractor concentrate on management strategies in term of tender process, type of contract, schedule control, quality control, progress and payment, and subcontractor safety.

In order to understand how main contractor’s strategies manage their subcontractors, this report was conducted through contractor documentation. The result shows subcontractor control strategy in a local contractor. Major improvements are needed for the subcontractor control strategy in local contractor in order to improve the subcontractor management performance. However, there are some major points, which need to be improved in order to strengthen and continually improve the strategy performance.

Executive summary

Rationale of research

This research has been conducted to identify Main Contractor’s strategy for managing  sub-contractors within a project.

Objectives of study

To study management practices of contractors in contractor’s for managing subcontractor in The Ever Rich II Project, Dao Tri Street, District 7, HCMC. Find out strengths & weakness to propose recommendations.

Methodology  

The exploratory research method is used to study management practices in Vietnam.

Findings and conclusion

In recent years, main contractor have been trending to use subcontractor in specific area accordingly like as specialist subcontractor, skilled-labor subcontractor and expertise provided by subcontractor. Especially building project, it is common for 80 percent to 90 percent of the work to be performed by subcontractors.

However, there are many subcontractors who do not have not enough expertise or skilled resources to undertake work satisfactorily and, as a result, they are not able to bring good services to clients or not reach their requirements. In order to resolve these problems that main contractor needs to develop a strategy that allows contractor to manage subcontractor effectively and efficiently.

According to the rationale stated above, this study to conduct an investigation of main contractor’s strategy for managing the subcontractor on construction project in terms of tender, unit price contract, schedule control, quality control, progress and payment, and safety.

Criteria Contractor’s Strategy

Tender           

o   Experience in subcontractor tendering.

o   Knowledge of material,resourses.

o   focus on long-term relationship subcontractor.

o   Changes in contract documents can be made easily by the contractor compare to lump sum contract.

o   Lower risk for subcontractor compare to lump sum contract.

Scheduling
