about us

Fundamental management/design philosophy is the commitment to bring the company’s owner-oriented, practical value added approach to development, which has been established and refined on projects undertaken by the company, to projects developed for every client.

CGI’s management strategy is specifically designed to: create a true public/private partnership through collaboration and cooperation with the client; complete the project as soon as possible through aggressive scheduling; maximize value by ensuring the most reasonable cost to the client; incorporate the best commercial practices in the design and construction industries. We believe that there are four basic qualities that are essential to the successful management of any project, which are: Leadership/Communication, Responsiveness/Flexibility, Design Excellence, and Quality.
