Systematic Approach for Determining Construction Contract Time: A Guidebook

The objective of this research was to develop a guidebook that DOTs can use to establish and maintain a systematic approach to determining credible and defensible contract times for projects using conventional and alternative contracting methods (e.g., design-bid-build without or with completion incentives and disincentives, design-build, construction-manager/general-contractor (CMGC), and other variations). The guidebook should address at least the following topics: (1) key factors that influence contract time duration and uncertainty, for example construction production rates, regional conditions, involvement of utilities, project priority or significance, technology advancement, and contracting strategy; (2) a framework for defining and evaluating the components of contract time, such as construction methods, site conditions, and project scope and complexity; (3) definition and measurement of effectiveness of techniques and processes for contract time determinations; (4) methodologies for making credible and defensible estimates of contract time; (5) the relationship of contract time to risk management; (6) strategies for post-project contract-time evaluation and other methods to improve effectiveness of contract time determination; and (7) strategies for developing, maintaining, and effectively applying experience and knowledge of contract-time determination throughout the agency.
