Construction Management, Administration & Inspection

Our professionals have overseen hundreds of construction projects ranging from small arterial street improvements and highway projects, to complex bridge/structures and aviation projects.

Project Controls

Our experience allows us to assist our clients with scheduling and estimating needs while plans are still in design. We use our expertise to institute value engineering techniques to save costs to our clients through claims reviews, constructability reviews, cost estimating and scheduling.


Our right-of-way services team assists our clients with land acquisitions, appraisals and relocations. Land acquisition and right-of-way management require a highly integrated approach. Our dedicated team remains involved throughout the life of a project.

Engineering Surveying

Our well established engineering surveying team provide our clients with accurate, timely and cost effective services across a full spectrum of land surveying and mapping applications.


We assist clients in the permitting process by reviewing the developers’ permits and ensuring their building permit is constructed correctly when it encroaches a right of way. CEI personnel are familiar with the preparation of permitting forms, what steps are needed in order for the permit to go through final approval, and distribution of the permits once approved.
