Quality Assurance and Control

CHIN furnished a Liaison Engineer and adequate staff to perform the duties required to fulfill the engineering requirements in accordance with the departmental

policies while providing tools of the trade, including an office computer system capable of running Construction and Materials Management System (CMMS) software. CMMS allows on-site inspection as well as implementation of layout and design changes not provided for in the contract plans. The CMMS also enables geotechnical inspection and testing, prepares records, maintains documentation, submits pay estimates, change orders, and any other duties that would require the services of an engineer to complete this project.
