CBG’s proven preconstruction process adds value by shortening schedules, minimizing changes, and generating savings.

We work in cooperation with clients and design teams during planning to address critical items before construction start, realize project goals, and deliver maximum value. Our team approach means we routinely work alongside in-house and outside experts in mechanical and electrical systems, foundations, structural detailing, and scheduling.
