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:
- 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
- ·A framework for defining and evaluating the components of contract time, such as construction methods, site conditions, and project scope and complexity
- Definition and measurement of effectiveness of techniques and processes for contract time determinations
- Methodologies for making credible and defensible estimates of contract time
- The relationship of contract time to risk management
- Strategies for post-project contract-time evaluation and other methods to improve effectiveness of contract time determination
- Strategies for developing, maintaining, and effectively applying experience and knowledge of contract-time determination throughout the agency
