Equipment Pad Coordination Guide
How to review housekeeping pads, rooftop pads, generator pads, transformer pads, and equipment bases across structural, MEP, civil, and access drawings.
Equipment pads provide elevation, support, vibration control, anchorage, drainage separation, and protection for mechanical, electrical, plumbing, and specialty equipment. They are simple details with many coordination dependencies.
A pad should be reviewed with the equipment, utilities, structural support, housekeeping requirements, and service access shown together.
What to Verify
Start with the equipment schedule and cutsheet, then compare the pad size and location against room plans, roof plans, structural framing, utilities, and door access.
- Pad length, width, height, reinforcement, and finish.
- Equipment footprint, anchor pattern, vibration isolation, and curb requirements.
- Electrical, piping, duct, drain, gas, condensate, and controls routing.
- Working clearance, service side, replacement path, and door swing.
- Drainage, snow, flood, vehicle impact, and roof warranty constraints.
Common Misses
Common pad problems include pads that are too small for the selected equipment, anchors that land near slab edges, condensate drains with no slope, and access clearances blocked by nearby walls or piping.
The safest review is cross-discipline because the pad itself rarely shows the full coordination problem.
