Concurrent Delay Analysis: Part 3
By: Charles Choyce
In parts 1 and 2, I discussed the definitions and general standards set forth by the Association for the Advancement of Cost Engineering International (AACEI) Recommended Practice to determine concurrent delay. In this post, I will illustrate challenges confronted in attempting to apply those concepts, which are by their nature very fact intensive.
Let us use as an example a typical office building with concrete foundations and a structural steel superstructure. The baseline schedule provided that the critical path ran through the construction of the foundations, followed by the start of structural steel erection. However, due to delays in resolving structural steel design problems by the owner’s structural engineer, the project’s critical path shifted to the structural steel design. The delay in resolving the design issues delayed by 100 days the fabrication of steel necessary to commence the erection, resulting in the project completion being delayed by 100 days. At the same time, the contractor completed the foundations 20 days later than planned.
