Concept: Projects begin with conversation, listening, and completely understanding a client’s needs. Once we have a detailed understanding of the client’s goals we begin what is known as the concept phase. Through collaboration we are able to develop solutions to complex problems.
Design: After the concept phase is design development where the project comes to life. These design solutions include new construction, renovations, additions, and tenant fit outs. From simple every day solutions to multifaceted and phased projects, DCA is capable to handle any scope of work that may arise. Design services we offer include: feasibility studies, existing conditions field surveys, preliminary design, design development, code review, interior design, landscape design and construction control.

DCA will produce a model of your project in CAD and 3D software to provide you with a model that is easily consumable which improves project efficiency and reduces overall project costs.

Through our construction administration process we are able to offer administration services that include: bidding and negotiations, permitting, project management, construction control affidavits, site observations and final punch lists. Our goal is to provide you with no surprises and that your needs are beyond fully met. Our services are not complete until our client is able to utilize their new space as they envisioned.
