POR and BIM Development for Buildings 1, 8 and 21

As part of a task order contract Global Engineering Solutions provided separate “Requirement Documents” packages for Buildings 1, 8, and 21 for a total of three (3) separate and independent packages for repair and upgrade of existing electrical systems in each of these buildings. The main intent of the contract was for GES to provide an As-Built A/E set of documents for each building.  The development of the Building Model required a complete team of professionals with experience in converting existing structures and facilities into BIM, and verification and converting of field measurements, scanned file and existing prints to Revit. The approximate square footages were Building 1 – 100,000 sf; Building 8 – 100,000 sf; and Building 21 – 40,000 sf.

The project began with the development of a Building Information Modeling Execution Plan, which outlined the process for measuring, verifying, updating, and converting the documents into Revit.   Laser scanning was used to establish the overall dimension of the building, as well as the interior spaces and served as the baseline for the development of the Revit model.  GES’ engineers conducted assessments, and field verified the sizes and location of the mechanical, electrical, plumbing and fire protection system within the building.   This information was used to update the Revit model and to provide a complete picture of the existing conditions.
