JCI Mega Block 

Chiller Performance Test Facility

San Antonio, Texas

The Mega Block Test Facility is a two-story structure totaling 38,500 square feet. The space is divided into the following areas:

  • Two test chambers called “Test Blocks” where customer chillers are brought in and connected via flexible hoses to the process piping system
  • Pump room containing the customer areas, control rooms and process pump room
  • Mezzanine floor housing process mechanical and electrical equipment
  • Rooftop containing process cooling towers, process chillers and building HVAC equipment

The scope of work was divided into two parts; the process piping work directly for the Owner and the building electrical & HVAC, which was under a General Contractor. Brandt’s scope of work included the process piping systems located throughout the facility.

Prior to mobilizing the job, our team extensively reviewed the BIM model to ensure accurate installation. This review confirmed that:

  • Pipe fittings and connections shown could be built without violating piping industry standards
  • All owner furnished equipment was modeled properly and all connections were in the correct location
  • Piping shown in the BIM matched all owner provided Piping & Instrumentation drawings (P&ID’s)
  • All control device upstream/downstream pipe diameters could be met due to limited space
  • Being able to properly hang/support all piping while dealing with multiple layers of piping
