About Us

Design Build

In a design-build project, Groen Construction acts as a single point of contact for an Owner by hiring the architects and engineers necessary to design and build the project as part of our contract.  With a focus on collaboration, efficient use of funding, timely decision-making and risk mitigation, the design-build delivery model continues to offer benefits within both the public and private realms. This approach treats the project planning, design and construction phases as integrated tasks within the construction system. These tasks are assigned to a Design-Build team consisting of the Owner, the Construction Manager and the Architect/Engineers.


The Pre-Construction phase at Groen Construction offers a wide range of services directed at thoroughly evaluating the needs of our customers and their projects before breaking ground.  Pre-construction services go well beyond just estimating what a project will cost. They include everything from an initial client meeting to review plans and concepts, schedules, studies, value engineering, permitting, land acquisition, and more.

Pre-construction services are used to help meet a client’s vision as well as match their construction budget. During the design process, pre-construction cost estimates are created to help with the owner’s decision making. These early estimates are supported by schematic designs and previous jobs of similar scope. From here, the job would move to a design development stage and finally the construction document state. This is a major cost-saving opportunity that will allow a construction project to flow more smoothly.

Construction Management

The Construction Management team acts as consultant to the Owner in the development and design phases, and serves as a general contractor during the construction phase. The Construction Management team contracts directly with multiple subcontractors and has single point of responsibility for the delivery of the project. As the construction manager, owners and developers depend on Groen Construction to identify and incorporate value engineering opportunities throughout the construction process, and to maintain strict budgets and schedules. As construction managers, we ensure meticulous administration of the project and seamless transition between all phases of design, pre-construction, and construction.
