Construction Modeling Stage
At the construction modeling stage of a project, subcontractors use a wide range of modeling tools like Tekla, Civil 3D, or AutoCAD FAB. To maintain continuity between the design models and the construction trade models the duplicate Element ID from the design models were used for the appropriate elements in their models.
Many times owners have specified native Revit as being the final handover model format and this is fine as the purpose-built trade modeling tools for construction often don’t have properties such as install date, warranty start date, warranty length, installer, etc., which aren’t relevant to contractors, but are very important to owners and FM. But other important information was gathered from the construction trade models like manufacturer, part number, cost, etc. For this project, we exported the data from the construction modeling tools to IFC. Then, we used the BIM Assure IFC Explorer to publish the IFC model and data to BIM Assure.
Construction Data Gathering Stage
Once in the construction data gathering stage, installers, test engineers, and commissioning agents can enter additional data directly into BIM Assure, augmenting the already collected data from the trade models. On a regular basis, the data manager for the project can run rules to ensure the data is complete and meets the owner’s handover requirements. This ability to test the data easily while it’s being added to is unique to BIM Assure and is critical for a successful handover.
