What we do

We see things differently: We understand owner objectives and how to solve construction project challenges from concept to occupancy. Through this process, we build Partnerships for Life.

Pre-Construction

Before construction begins, TW is ready to work—collaborating with owners and stakeholders to develop cost-effective solutions and realistic construction timelines.

General Contracting

TW Standards are high! We assemble experienced teams, realistic project schedules, maintain accurate cost controls and ensure effective lines communication throughout projects.

Construction Management

Decades of industry experience give the TW team insight into owners’ expectations and the challenges associated with projects of all scales, across most sectors and through multiple project modes.

Design-Build

TW’s design-build process assures our clients their project will benefit from cost-saving alternatives, complete design coordination, and accelerated project delivery—all under a single contract.
