AECOM Design (formerly DMJM H&N)
U.S. CAD worked on the MEP design for this Caltrans' (GSA) project on behalf of AECOM Design. You can see that we modeled several large pieces of equipments as shown here above along with the HVAC systems and mechanical piping systems in this high resolution rendered image.
Above is a larger view of all of the HVAC systems, mechanical piping systems along with the electrical conduit. You can see that U.S. CAD was able to coordinate all of this geometry together in order to check for any design flaws or collisions prior to construction.
Here is one final image of the Caltrans GSA project for AECOM design showing the exterior structure of the building that contains the MEP systems we modeled for AECOM.
