The HVAC Briefing

Wake Forest University needed more cooling capacity to support campus growth, but the existing central plant footprint left little room for expansion. RMF Engineering partnered with architect Michael Graves — known for postmodern institutional buildings — to thread the needle: add tonnage, improve efficiency, and maintain the visual coherence of a historic campus. The project required coordination between mechanical design, structural constraints, and architectural review processes that many contractors face on university and hospital work.

Campus chiller plants typically run 24/7 during cooling season with load diversity across residence halls, labs, dining facilities, and lecture halls. Upgrading without disrupting summer session or research operations means sequencing equipment deliveries, rigging through constrained access points, and maintaining redundant capacity during commissioning. RMF's design likely incorporated variable primary flow, high-efficiency centrifugal chillers in the 800-1200 ton range, and upgraded cooling tower cells to match the increased heat rejection load. Contractors bidding these jobs need to account for after-hours installation windows, temporary chiller rentals during cutover, and specialized rigging for equipment that won't fit through standard dock doors.

The Michael Graves involvement adds another layer. Graves-designed buildings often feature specific material palettes, louver styles, and roofline details that must extend to mechanical penthouses and yard equipment enclosures. That means custom louvers with specific blade spacing, masonry screening walls instead of chain-link, and coordination with campus planners on sight lines from pedestrian paths. Mechanical contractors should price architectural screening and enclosure work separately — it's not included in standard chiller plant specs and can add 8-12% to the mechanical budget.

If you're quoting campus or hospital central plant work this year, walk the site before pricing. Measure door widths, ceiling heights in mechanical rooms, and crane access from the nearest staging area. Ask about summer blackout dates when you can't interrupt cooling. Budget 15-20% more labor for night and weekend work if that's the only option. Stock relationships with rental chiller suppliers who can deliver 400+ ton trailer-mounted units on short notice. And if the project has an architect of record with strong design opinions, build in time for submittal reviews and potential custom fabrication — that's where change orders originate if you underprice the front end.

As campuses electrify and add data centers for research computing, central plant upgrades will accelerate. Engineers who can solve capacity problems on constrained sites without compromising campus character will win repeat work. Contractors who understand the operational constraints and price accordingly will stay profitable on these multi-year relationships.
