| Summary: | 碩士 === 逢甲大學 === 土木工程學系 === 103 === The construction industry involves numerous complicated and versatile teams from planning, design, construction, supervision, and operation, with the information transfer mainly based on a huge amount of plan view drawings and documentary data which also serves as the basis for construction. However, the plan view drawings are limited by the subjectivity of spatial thinking such that it can be difficult to be used for assessment the tasks and spatial relations of the construction projects. In addition, the possibility of information wrong information during transfer of documentary data may lead to design variation of the construction project thus causing delayed progress and increased costs. The lack of universal construction project control approach among different teams will result in controversies and unnecessary costs upon occurrences of project delays, poor qualities, and budget overruns.
This study is focused on an ongoing construction project based on plan view drawings to investigate the predetermined cost schedule, actual project expenditures, construction project monitoring, and performance evaluation of a structural construction project via the knowledge field of Earned-Value Management. The building information modeling will also be established to understand how the error of plan view drawings results in extra project expenditures and poor implementation performance.
In this study the first project audit has revealed the expected loss of total construction cost of 30% with the total schedule delay of 17 days; the second audit has revealed the expected loss of total construction cost of 26% with the total schedule delay of 15 days; upon completion of the construction project, the total loss of construction cost is at 11% yet there is no delay of the overall project schedule. It is found during the process of establishing building information modeling that the review and improvement of erroneous information of plan view drawings and items requiring design variations before the start of construction project can result in the saving of construction cost by around 11%.
