Cornerstone General Contractors | Safety Culture.

Safety is our number one priority.

Cornerstone is passionate about conducting safe projects. It is our responsibility to create and manage an effective accident prevention program. No injury is acceptable. We promote a culture of safety with the expectation that work will be performed free of accident or incident.

“The safety of employees, clients, subcontractors, vendors, the public, and company operation is of paramount importance and shall take precedence over expediency or shortcuts. Safety is the responsibility of all project participants.”

Through our extensive experience with K–12 projects in the State of Washington, we are highly attuned to meeting WSSP (Washington Sustainable Schools Protocol) and LEED (Leadership in Energy and Environmental Design) requirements. Nearly all of our projects have demanded high sustainability goals. Cornerstone has successfully worked with project team partners to achieve certification for each of these.

Technology

Technology is an integral factor in modern construction. Cornerstone leverages it to create efficiencies in pre-construction and construction processes that provide our clients with the highest return on investment. We are well versed in using virtual construction technologies and work closely with each client to create a plan that meets their individual needs while optimizing the value added to their project.
