Accounting for ATCs in Design 33 The third ATC scope risk issue deals with the degrading of overall project quality to find cost and time savings. This risk is typically an artifact from the low bid mentality that still pervades the highway construction industry, but it remains present in most procurements.

34 Guidebook for Implementing Alternative Technical Concepts in All Types of Highway Project Delivery Methods 3.4 Design Packaging This section will cover the concept of packaging the design into several features of work that align with the anticipated subcontracting plan, to make it easier to evaluate changes imposed by a proposed ATC, as well as to facilitate the allocation of design risk. The SHRP 2 Report S2R10RW1: Project Management Strategies for Complex Projects (Shane et al.

Accounting for ATCs in Design 35 stifle potential time and cost savings brought by ATCs. A typical clause from a DOT ATC guidance manual addresses the issue in this manner: All applicable laws must be followed for the project development including specifically, but not limited to, environmental clearance, ROW procurement and utility work.
