Through the use of Building Information Modeling (BIM) and Virtual Design and Construction (VDC) technologies and methodologies, APG offers these services to clients on nearly all of our complex projects. VDC increases efficiencies in production, reduces late changes during the course of construction, minimizes rework that results in additional cost or extensions to the construction schedule, and improves operational efficiencies throughout the life of the building. 

APG Engineering has extensive experience in developing 3D BIM models using Autodesk Revit and Autodesk Navisworks software. Our models are active throughout the entire design and construction process, being continuously updated to reflect the on-going changes that occur on a routine basis. These models are not only used for system coordination and clash detection, they are routinely scaled and used as installation drawings.

Often associated with the Integrated Project Delivery (IPD) methodology, APG Engineering feels the accuracy and timing of the 3D BIM is essential to realizing the many benefits associated with this method. Some of these benefits are:

• Coordination of utility services and building systems
• Early identification and resolution of system conflicts (Clash Detection)
• Compressing construction schedule
• Construction cost reduction
  
• Reduction in Requests For Information (RFI) and Change Orders
  

When construction is completed, our 3D BIM models may be converted to digital As-Built models to be used by the owner in their Operations and Maintenance programs.
