Validating the BIM coordination model throughout construction, using laser scanning, is a progressive approach to ensure the model is within tolerance of the as-constructed conditions of a project. If any out-of-tolerance installation errors are discovered, the BIM model can be updated to reflect the accurate as-built conditions. This process will help prevent costly on-site changes and prefabrication errors, as well as enable the delivery of an accurate BIM model to the owner.
Through BIM Point Layout, it is possible to minimize the disconnect between the coordinated BIM model and trade contractors in field. Manual layout is vastly prone to human error, which deteriorates the accuracy of the BIM model over the duration of a construction schedule. By incorporating survey point layout in the BIM coordination process, owners and contractors will see increased efficiency, smarter ways to accomplish tasks, better control of cost and time variance and higher value at a similar or decreased overall cost.
