Machines vibrate, and the pad under them decides whether that vibration stays in the machine or travels through the building. Compressors, presses, chillers, generators, process tanks and transformers all sit on concrete that was designed for a specific weight, a specific dynamic load and a specific set of anchor bolts. We build equipment pads and machine foundations for plants and small-bay shops in the Santa Fe region, and we treat each one as a small structure rather than a slab with a few bars thrown in.
The work starts with the equipment submittals. The weight, footprint, bolt pattern, vibration characteristics and service clearances all come from the manufacturer, and they decide the pad size, depth and reinforcement. We read those documents with the engineer before forming begins, because a pad poured to last month's equipment model is one of the most common and most expensive mistakes in plant work.
Our clients are operations and engineering leads adding or replacing equipment in a building that has to keep running. We plan the cutting, excavation and pour so the plant loses as little production as possible, and we leave the floor and the surroundings as quiet and clean as we found them.
What equipment work looks like around Santa Fe
Industrial work in this metro tends to be incremental rather than monumental. Los Alamos National Laboratory reports almost 900 individual facilities across 8.4 million square feet of buildings, and the supply chain that feeds it includes machine shops, fabricators and testing operations that grow one piece of equipment at a time. A new press, a new test stand or a standby generator is the typical job, and each needs its own foundation.
Automotive and light-industrial users add their own demands. A 7,000 square foot service center opened on Pueblo land at Nambe in 2021, an example of the small, specialized facilities that need lift bases, charger pads, alignment slabs and equipment platforms. For clients in automotive and EV service, we build pads for hydraulic lifts and fast-charging equipment to the manufacturer's tolerances, and we coordinate with the electrical contractor on conduits cast into the base.
Coordinating forming, reinforcing and pouring
We coordinate forming, steel placement and pouring of the pads. That matters because pad work depends on small details: anchor bolt templates held at the correct projection, sleeves and embeds in the right position, leveling nuts and grout space allowed for, and a top surface finished to the tolerance the manufacturer's installation instructions call for. The formwork and reinforcing trade partners read the shop drawings, and the person setting the bolts is the person who checks them.
We handle the tie-in to the existing building when the pad is inside. Cutting the slab with a saw to avoid damaging the surrounding floor, excavating without undermining nearby footings and dowelling the new concrete into the old are all controlled operations. Where a machine needs isolation from the floor, we build the pad on its own thickened base with a joint around it and fill the joint with a resilient material.
The range of pads we build
Typical projects include generator and transformer pads, chiller and compressor bases, tank foundations and containment, rooftop curb supports, press and machine tool foundations, conveyor supports, loading ramps and charger pads. Outdoor pads are sized for frost and for the lateral loads of wind and seismic design, and indoor pads include provisions for conduits, cable trenches and equipment access.
Heavier or more sensitive equipment may need more than a mat. A tall column or vibrating machine may call for piers or piles beneath the pad, and we coordinate those with deep foundations and piers when the soil or the load requires it. For equipment that is supported on elevated structure, we work with mezzanines, catwalks and platforms and structural steel erection so the steel columns bear on proper footings.
Coordinating pads with equipment delivery
The pad is the gate for the equipment. If it is not cured and surveyed when the machine arrives, the delivery waits, and storage and rigging costs start. We schedule the pour so concrete reaches the manufacturer's required strength before setting, typically after several days of curing for light equipment and longer for heavy items, and we survey the finished pad before handing it to the millwright.
We keep in contact with the rigger and the vendor so the delivery date, crane access and setting sequence are known. A well-planned set usually takes a day or two. Long-lead equipment, such as large transformers or custom machine tools, often arrives later than the original schedule, so we pair the work with industrial concrete floors and the building's own sequence rather than holding the pour idle.
Code and coordination
Pads connect to mechanical and electrical systems that fall under state codes. The 2024 New Mexico Plumbing Code and Mechanical Code took effect August 1, 2026, with permits issued under either the 2021 or the 2024 edition until January 1, 2027 and only the 2024 edition afterward. We confirm which edition the permit uses and make sure clearances, support and access for equipment meet the applicable code.
We coordinate with the mechanical contractor, the electrician and the equipment vendor from layout through startup. For owners building automotive and EV plants or similar facilities, we assemble a pad schedule listing each pad, its design load, its bolt pattern and its pour date, so the field has a single source of truth.
Send the submittals
Share the equipment drawings and the target install date. We will confirm the pad design with your engineer, plan the work around production and have the foundation ready when the machine rolls in.
Common Questions
How soon after a pad is poured can heavy equipment be set?
That depends on the concrete strength the manufacturer or engineer requires, not a fixed number of days. Many pads reach working strength in about a week with a normal mix, and cylinder breaks confirm it. We will not release a pad for setting until the test results meet the specification.
Do I need a separate foundation for vibrating equipment?
Often yes. A machine that vibrates or has reciprocating loads needs a pad isolated from the building slab, with a gap or resilient joint around the edge. The vendor's installation guide and the structural engineer determine the mass and depth. We build to those details and keep the joint clean of debris.
Can you add a pad inside an operating plant?
Yes. We cut the slab in sections, control dust with vacuum saws and enclosures, and haul material out through the least disruptive route. Work often runs during off-shift hours or on weekends to limit the impact on production.
What permits does an equipment foundation need?
Large pads, tank foundations and generator bases usually need building and electrical permits, and some need an engineer's stamped drawings. The details depend on the equipment and the jurisdiction. We prepare the sketches and structural details the permit office asks for.
How are anchor bolts held accurately?
We use steel templates built from the manufacturer's bolt pattern, tied securely to the reinforcement and checked with a survey before the pour. After the pour we verify projection and location again. Accuracy at this stage avoids drilling and epoxy fixes after the fact.
