Commercial/Core & Shell

In the commercial construction management world, time is money.

Whether need is driven by an expiring lease, non-negotiable dates for employee moves, or the need for a new space that reflects a redefined corporate vision, BW Kennedy & Co. recognizes that commercial work is an extension of the client and their need.

We will work to maximize space, decrease schedule, and provide project savings, allowing clients to more quickly occupy their space and go about conducting their business.
