Request for information (RFI) is considered as one of the important administrative tools in construction projects. It can be used as an indicator on how well the coordination between parties, especially between contractors and engineers and/or supervisors, performed in a project. Delays in a construction project could be identified by analyzing the RFI documents, but on the other hand, they could also be caused by poor administrative in handling the RFI documents and by delays in processing RFIs. This paper reviews the performance of four building projects in handling their RFI documents. The four buildings were constructed by a national joint- operation contractor, designed and supervised by an international joint-operation consultant. The RFI responses and wok-in-process were used to measure the project’s performance in handling the RFI documents; from the contractor’s and the engineer’s point of views. The analysis results show that the engineer had been very responsive in processing RFIs, while the contractor had difficulties. In general, the contractor was lack of capable personnel in handling RFIs for all four buildings. Moreover, communication problem was the key of the project’s performance due to different language and culture. The authors believed that the results of the analysis would influence to the overall project performance.
