Construction Management

Resident Inspection Services

The Port of Caddo-Bossier is a “smart” industrial park that works well for business relocation, business expansion, and business start-up. It is one of the most accessible inland ports because of its ideal location. It is also a multi-modal transportation and distribution center that links customers throughout the region to domestic and international markets. Manchac Consulting Group, Inc. provided Resident Inspection to all of the Port’s construction projects and general construction management services.
