According to 23 Code of Federal Regulations 635.121, state transportation agencies should have adequate written procedures for the determination of contract time. With increasing traffic volumes and an increase in the number of projects constructed under traffic, there are greater impacts to traffic by construction activities as well as more visibility by the traveling public. Contract time procedures are needed to aid in uniformly and appropriately selecting the method for the assessment of contract time and determining the required amount of time to promote contractor efficiency and reduced impacts to traffic.
