PreconstructionServices
As a preconstruction adviser, Ahern’s knowledge and experience benefit general contractors, architects, and building owners through early involvement in system selection that meets the end user's goals and budget.
Early collaboration also ensures our designs follow proper code and occupancy requirements to mitigate design changes after a project has been initiated. Using Building Information Modeling and CAD software, our teams will explain the system design, as well as identify ways to get the most from these systems, reduce life cycle costs, and eliminate system interferences.
