Engineered Equipment Pad Concrete for Pittsburgh Sites
Generators, HVAC units, transformers, and tanks all need a concrete foundation that holds them level, resists vibration, and keeps anchor bolts in the exact position the equipment frame expects. Pittsburgh Concrete designs and pours equipment pads to the loaded weight and vibration class of each unit, templates every anchor pattern before the pour, and coordinates with your equipment installer so the pad is ready when the unit arrives. Free written estimate on every project.
A pad that looks adequate often isn't. The concrete slab must carry the equipment's full loaded weight (a water-filled HVAC unit weighs significantly more than its dry spec), absorb the vibration cycles the equipment generates during operation, position anchor bolts so they thread into the equipment's mounting frame without forcing or shimming, and remain stable through Pittsburgh's freeze-thaw cycles.
We start with the equipment manufacturer's cut sheet to determine loaded weight, vibration class, anchor spacing, and any isolation requirements. The slab is reinforced to those loads, footings are dug below frost line for exterior installations, and anchor bolts are held in a template during the pour so they emerge at the exact height and spacing the equipment expects.
We obtain the equipment cut sheet (footprint dimensions, loaded weight, vibration rating, anchor bolt pattern, isolation requirements) and use those specs to design the pad rather than applying a one-size-fits-all template.
Excavate and prepare the base
For exterior pads, we excavate below Pittsburgh's frost line, compact the subgrade, and place a gravel base to the engineered depth so the pad will not heave during winter.
Build forms, place reinforcement, set anchors
Forms are built to the pad dimensions, rebar is tied per the load calculations, anchor bolts are positioned using a template that matches the equipment's mounting frame, and vibration isolation embeds are placed if required.
Pour, finish, and cure
Concrete is placed and finished to the elevation the equipment expects, protected through cure, and handed off to the equipment installer with verified as-built dimensions and anchor bolt heights confirmed.
The most common issue
Anchor Bolts Out of Position Cost Time and Money
Equipment installers arriving on site to find anchor bolts that don't align with the equipment frame face delays, costly shimming, or worse, a pad that must be demolished and replaced. Most equipment pad disputes trace back to anchor bolt positioning. We template every anchor pattern directly from the equipment cut sheet and verify bolt position during the pour, not after concrete has cured.
Coordinate with the equipment supplier early so the cut sheet drives the pad design. Equipment pads often run alongside ADA ramp or curb and gutter work on the same site, and we sequence all concrete work to keep the project on schedule.
Anchor patterns, vibration isolation, sizing to loaded weight and equipment-installer coordination.
The pad has to support the loaded weight of the equipment (full of fluids, under service load) with a margin, and provide enough footprint for the anchor pattern plus access for maintenance. We size from the equipment cut sheet, not from generic tables.
We template the anchor pattern from the equipment cut sheet, build a wood or steel template that holds the bolts in exact position, and place that template in the form so the bolts are anchored during the pour at the right spacing and projection.
Some equipment requires it (especially generators, compressors). We use vibration isolation pads or specialized embedded systems per the equipment's spec sheet. Not every pad needs it; we follow what the equipment requires.
Exterior equipment pads need footings below the frost line in Pittsburgh, which is typically several feet. Interior pads on existing slabs can be much shallower or even tied into the existing floor depending on load. The engineering drives the depth.
Equipment installers typically wait for the pad to reach a specific cure strength before mounting the unit; for most pads that is within a few days of the pour. We give the installer the cure timeline so installation schedules without delay.
Client reviews
What Pittsburgh Operations Say About Their Equipment Pads
HVAC pad with anchor bolts that lined up exactly with the unit frame. The HVAC installer commented that it was the easiest install he had done that month. Templating is everything.

★★★★★
Generator pad engineered for the unit's vibration and weight. Three years of regular generator runs, zero crack development, zero shift. The engineering held.

Industrial Operations Director, Aliquippa
★★★★★
Transformer pad replacement during a planned outage. Coordinated the schedule tightly with the utility, pad cured and ready in the window. Power back on as scheduled. Real timing discipline.
Z. P2
Property Manager, Monroeville
★★★★★
Multiple equipment pads across a plant expansion. Every cut sheet honored, every anchor template right, every pad finished to the elevation the equipment expected. No improvisation, no surprises.
