It is recommended to create a construction site mock-up in the planning or early construction stage, prior to a significant amount of installation. Early mock-up allows for architects, engineers, contractors and clients to review and approve materials, finishes and construction methods. The construction site mock-up is a useful reference point during construction and aids in communication between stakeholders. By assessing the project early on, it is possible to adjust the project as necessary before it is too late, which will avoid excessive delays and project expenses.
