Design Build

Onekey, LLC has the ability to undertake all management tasks at the design phase on behalf of the client. Based upon Onekey’s relationships in the development, design, and construction industries, we assemble design/build teams to meet specific requirements of each project. Through these partnerships, Onekey adds value to the design through constructibility, budgeting, cost control and logistical input.

By staffing the project with construction professionals during the planning and design phases, the team fully understands the project goals, technical details and key issues before construction begins. Once it is time to start construction, our team is already on the move, executing the job in accordance with contract documents, and building a successful project for all stakeholders.
