Preconstruction services by the general contractor improves predictability and reduces cost overrun risk. At Overaa, our unique brand of preconstruction provides clients expertise from project teams with self-performing construction know-how and subcontractors from a diverse range of disciplines.  Led by knowledgeable teams with access to a depth of industry leading resources, Overaa offers leadership and cost saving opportunities to improve project outcomes.

Overaa uses Building Information Modeling (BIM) or Virtual Design and Construction (VDC) to lead the collaboration effort on a project. By using three-dimensional, dynamic building modeling software, such as Revit or Navisworks, we can eliminate many uncertainties found in the field. Engaging the design team and design-build subcontractors to work in a shared BIM platform supports early collaboration among stakeholders. We use the latest and greatest technology to allow our teams to leverage their deep construction and project knowledge. Ultimately, the use of virtual building technology results in a more accurate and predictable construction process.

We believe preconstruction improves four essential elements of a project:

  • cost control and budget management
  • project collaboration and team building
  • schedule management for all project phases 
  • value engineering and constructability recommendations

During preconstruction a major Value Engineering effort was undertaken to remove approximately $900,000 from the budget without significant change to the project program or appearance. In spite of numerous setbacks, Overaa met the client’s aggressive, 13 month schedule, and at close-out provided the client with a refund of $284,000 below the established Guaranteed Maximum Price.
