When a body shop foreman in central Iowa calls us about adding an auto lift, the question is almost never “which lift is best” — it’s “what do I need to do first so this doesn’t turn into a mess.” We’ve walked enough garages to know the order matters. Concrete, clearance, power, and drainage all have to line up before the equipment shows up on the truck, and skipping a step usually means paying for it twice. As an Iowa-based installer and parts supplier, we sequence auto lift build-outs for shops of every size, and this guide walks through that order the way we’d explain it standing in your bay.
Whether you’re planning a new bay or replacing worn components on an existing setup, our parts lookup covers cables, cylinders, and hydraulic parts for every major brand we install.
Start With the Slab, Not the Catalog
Every build-out conversation we have starts with concrete, because a shiny new auto lift means nothing if the slab underneath it can’t hold the load. We ask about slab age, thickness, and whether there’s any patch work or old anchor holes in the footprint you’re planning to use. A four-post drive-on unit and a two-post asymmetric lift have different anchor patterns and different point loads, so the answer to “will my floor work” depends on which auto lift you’re actually buying, not just its rated capacity.
We’ve had foremen assume their existing floor was fine because an old lift once sat there, only to find the prior installation used a thicker pour or different anchor spacing. If you’re building a new bay from scratch, get the slab spec in front of us before you pour — 4 inches of standard mix isn’t the same as what a heavy-duty two-post needs. If you’re retrofitting an existing bay, we’ll come look at it. This is the step that saves the most grief later, because moving concrete after the fact costs far more than pouring it right the first time.
Measure the Ceiling and the Doorway Before You Commit
Overhead clearance kills more auto lift plans than any other single factor, and it’s the thing shops most often skip until the equipment arrives. A two-post lift needs headroom for the vehicle plus the lift’s own overhead travel, and if you’re running a lift with an overhead beam design instead of a floor-plate model, that number changes again. We measure to the lowest obstruction in the bay — ductwork, lighting, sprinkler heads, not just the roof deck — because that’s what actually limits how high a vehicle can go.
Door width and height matter just as much, especially if you’re bringing in a taller service truck or a dually on a regular basis. We also look at column spacing relative to your bay’s structural posts and adjacent equipment; a lift positioned too close to a neighboring bay makes door swing and vehicle drive-on awkward every single day, not just on install day. Getting these measurements settled before ordering means we’re quoting the right footprint the first time instead of re-measuring after a lift shows up too tall for the space.
Sequence the Power Drop and Air Lines Early
The power unit on most two-post and four-post lifts has to sit close enough for its cables and hoses to reach the columns, which means electrical needs to be roughed in before the equipment lands, not after. We tell shops to get their electrician scheduled based on the lift’s actual voltage and amperage requirements, not a guess, because upgrading a circuit after drywall and conduit are in is a needless expense. If you’re also running impact tools or air-actuated jacks off the same lift bay, sequence your air line drops at the same time as electrical so you’re not opening walls twice.
We see this go sideways most often in build-outs where the electrical contractor and the lift installer never talk to each other. Tell us your contractor’s timeline and we’ll tell you exactly what the auto lift needs — voltage, breaker size, and where the power unit realistically has to sit relative to the columns. That one conversation, had early, prevents a rescheduled install date later.
Plan Drainage and Floor Coatings Around the Footprint
If your bay handles fluid changes, brake work, or anything that drips, floor drainage needs to be planned around where the auto lift actually sits, not wherever the drain happened to go in an old building. Drip trays help, but they’re not a substitute for slope and drains positioned to catch runoff from the actual work area under the vehicle. We’ve seen shops pour a beautiful new slab and coat it, then realize the drain is three feet from where fluid actually falls.
Epoxy and floor coatings should go down before the lift is anchored, not around it — trying to coat a bay after the base plates are bolted down leaves an obvious, sloppy border. Sequence this step right after your concrete cures and before your install date, and tell your coating contractor exactly where the anchor points will land so they can mask or plan accordingly. It’s a small scheduling detail that makes the finished bay look like it was actually planned rather than pieced together.
Decide on Ramps, Trays, and Accessories Before Install Day
We get a lot of last-minute questions about accessories — extended ramps, drip trays, caster kits — and the honest answer is these decisions are easier made before install day than after. Some ramp options come as a fixed length attached to the lift, while others are separate pieces that can be swapped for a different length depending on the vehicles you service most. If your shop runs longer trucks or trailers through the bay regularly, tell us that up front so we quote the right ramp configuration instead of retrofitting later.
Caster kits are worth deciding on early too, especially in shared or multi-use bays where the auto lift might need to move occasionally for detailing, alignment work, or seasonal reconfiguration. Drip trays and jack trays are easy to add at the accessory stage but annoying to retrofit once the lift’s been anchored and the floor coated around it. We build these into the initial quote whenever a shop tells us how the bay will actually be used day to day, not just what the lift’s spec sheet says it can technically hold.
Line Up Delivery Logistics Before the Truck Shows Up
A surprising number of build-out delays come down to delivery logistics, not the lift itself. We always ask whether there’s a forklift or skid loader on site large enough to handle a lift’s shipping weight, because columns and power units on a four-post can run into the thousands of pounds and someone has to be ready to unload them. If your shop doesn’t have that equipment, we can often arrange for it, but it needs to be sorted before the truck arrives, not discovered on the loading dock.
Access matters too — dock height, door width for the delivery truck, and whether the equipment needs to travel any distance from the drop point to the actual bay. Shops in tighter urban locations around central Iowa sometimes need a specific delivery window or a smaller truck to navigate the lot. We coordinate this piece directly with the freight company once we know your site conditions, so the equipment lands where it needs to be instead of sitting on a truck because nobody could unload it.
Schedule the Install and Inspection Like Any Other Shop Job
Once concrete, power, drainage, and accessories are settled, scheduling the actual auto lift installation is the easy part — but it still deserves the same planning you’d give any big job on your shop calendar. We work around your bay’s production schedule when we can, including evening installs for shops that need to keep bays open during the day. Tell us your busy season and slow season and we’ll try to fit around it rather than forcing a shutdown at the worst possible time.
After install, plan for a follow-up inspection, especially if the lift is going into a shop that services fleet or dealership vehicles under any kind of inspection program. We do periodic lift inspections for training programs and dealership groups across Iowa, and it’s much easier to build that inspection cadence into your maintenance calendar from day one than to scramble for it later. A well-sequenced build-out ends with a lift that’s not just installed, but genuinely ready for daily use.
