Construction Administration & Management

Our technical crews have the ability to understand the critical construction activities.

Sigma provides technical expertise to oversee construction requirements to build and assure designs are constructed using acceptable industry methods, materials, and equipment and in accordance with plans and specifications. With the understanding that optimal constructible bid documents reduce the contractor’s risk and cost, Sigma’s constructability review will emphasize on-site conditions, right of way, utilities, environmental impacts, traffic maintenance, construction phasing, and scheduling.

We are adept at keeping the owner apprised of project progress and activities—especially those that may change or delay construction. We carefully review technical specifications and provide recommendations for improvements.
