Abstract

Requests for information (RFIs) on construction projects facilitate communication between the contractor and the owner or designer. If responses to RFIs are not made promptly, they may cause delays. With alternative project delivery methods like construction manager/general contractor (CM/GC), the contractor participates in the design phase, which provides a much broader understanding of the design. This suggests fewer RFIs for these types of projects compared with the traditional design-bid-build (D-B-B) delivery method. Additionally, projects with alternative delivery methods are frequently on accelerated schedules, which would make them sensitive to RFI response time. Research has not addressed whether or how the CM/GC project delivery method relates to RFI response time, and by corollary, potential project delays. In this research, a simulation of the RFI process was developed using the Simphony simulation software. Probability distributions for RFI creation interval times and RFI response durations were developed from CM/GC highway project data. Preliminary results provide insights into the potential delays due to RFIs. Simulation results on a 3-year CM/GC highway construction project indicate that RFI review delays could potentially generate construction delays up to 10% of the construction duration.
