OUR PROCESS
During every phase of the design, our team will provide innovative constructability and value engineering ideas through a formal process. This process will be led by our certified facilitator. Each suggestion will be provided to the team and evaluated to decide whether to further advance the idea.
Advancing a suggestion may result in the need for cost estimating, value analysis or exploring a design for feasibility. In order to accomplish this, we utilize the Decision Analysis and Resolution Team (DART) tracking. The DART matrix organizes and quantifies innovations developed during design to help the team evaluate the overall change.
Each innovation is evaluated based on impacts to design, construction, schedule, the client and overall project goals and weighted scores are entered for each category. This allows the team to make informed decisions for every value engineered or innovative idea.
Because we're a local, Southern MD firm having worked projects in St. Mary’s County for the past 35 years, we are able to reduce the cost of construction and maximize value for our clients.
WE STAY ON BUDGET AND ON TIME!
