The project consists of miscellaneous repairs to the building and storage facilities at the Agrilife Research and Extension Center in Vernon, Texas. The facilities were damaged in a severe tornado and thunderstorm that directly hit the center on May 4, 2022. There are two main entities at the Vernon Center, the Research and Extension main Facilities and the Foundation Seed facilities. The main facility is comprised of the main center that houses Research and Extension administrators, laboratories, various offices, and public auditorium. Additionally, there are two buildings that contain major agricultural equipment, a chemical storage facility, plant & soil head house and three greenhouses. The main headquarters facility had at least 60% of its roof membrane and all HVAC equipment blown off the roof and destroyed by the tornado. In total, eleven enclosed structures comprising over 68,000 square feet require some sort of system rework – from complete replacement to simple repairs.
Salesforce Tower is the tallest tower in San Francisco, joining the Golden Gate Bridge and Transamerica Building in the iconic skyline. The high-rise building stands at 1,070 feet tall and 61-stories. The glass and metal accents on the exterior taper to accentuate the curved features of the building. The building is a novel approach to public-private collaboration and sustainability. Command Commissioning provided Fundamental and Enhanced LEED commissioning for this facility and commissioned the following equipment: chillers, cooling towers, boilers, heat exchangers, HVAC pumps, VFD’s, tripath AHU’s, VAV’s, DX split air conditioning units, fan/blower coil units, garage supply and exhaust, exhaust fans, transfer fans, building management & controls, lighting controls, and 600 volt feeders. Salesforce Tower connects directly to the transit center below grade and is built adjacent to a 5.4 acre public park. Sustainability features include the use of full outside air economizer ventilation systems, floor-by-floor air intake, under-floor air distribution, integrated metal sunshades, high-performance glass, floor-to-ceiling windows, and comprehensive water recycling systems.
This project consisted of the installation of four new 1,100 Ton chillers in the existing satellite central utility plant (SCUP) at Hobby Airport in Houston, TX. Upon completion of the SCUP, the existing Central Utility Plant (CUP) was decommissioned and demolished. The new chillers, cooling towers, and pumps allowed for N+1 redundancy in the SCUP. The new chilled water system was configured as a variable primary system with one set of variable secondary pumps serving the FIS Terminal. A bypass around the FIS secondary pumps was constructed to allow the primary pumps to serve the FIS when differential pressures and load allow. Our team developed a Method of Procedure (MOP) for transitioning the chilled water systems from the existing plant to the new SCUP that would allow us to test the SCUP without impacting normal airport operations.
