Contract Time Optimization Methodologies For Highway Construction Projects, Yi Jiang, Huaxin Chen
JTRP Technical Reports
This study was conducted to develop methodologies for appropriately determining the monetary values of I/D rates of highway construction projects in Indiana. In this study, a comprehensive literature review was performed to identify possible effective methodologies for work zone effects, construction impacts, and contract time optimization. The highway production rates were developed in a previous study. The production rates were validated and adjusted with the help from INDOT field engineers. The weighin- motion (WIM) collected traffic data were obtained, processed, and analyzed to provide input data for user cost calculations at highway work zones. Construction data were obtained and processed …

JTRP Technical Reports
Costs of highway construction projects have been rising with rising prices of construction materials such as asphalt, concrete and steel. Identifying cost saving strategies is one of the ways of efficient utilization of available funds (federal and local) by the state Department of Transportations (DOTs) and Local Public Agencies (LPAs). A case study comprising of a sample pair of projects (a federal-aid project and a 100% locally funded project) constructed in Elkhart County, Indiana was undertaken to compare construction costs when sources of funding vary. Based on analysis of cost details from these two projects and discussions with the general …
