One half-inch lip at a doorway can fail an inspection that the rest of the building passed. Accessible routes are unforgiving because the tolerances are small, the slopes are fixed numbers, and every piece of concrete between the parking space and the entrance has to line up. An industrial site feels like a place where sidewalks are a minor item, yet the walk from the accessible stall to the office door is often what the inspector checks first, and it is where owners most often face rework at the end of a project.
We build site concrete with accessibility in mind from the first form. That means curb ramps, landings, sidewalks, entry slabs, stoops, accessible parking stalls and the access aisle beside them, set out with the finished slopes and cross slopes laid on the grade stakes rather than hoped for during the pour. We measure, we correct before the concrete sets, and we give owners and inspectors a record of what was built.
The result is quiet, which is the point. Visitors, inspectors and employees walk from car to door without noticing the concrete, and the owner is not paying a saw crew and a second mobilization in the final week to fix an inch of slope.
Every piece of the accessible route
Our scope covers flatwork from the public way and the accessible parking through to the building. We place curb ramps with the specified slopes, landings and flares, detectable warnings where they are required, and sidewalks at widths and cross slopes that comply. Accessible stalls and their access aisles go in at the right dimensions with level surfaces, and entry slabs are poured to meet the door threshold without creating a lip.
Other site concrete follows the same discipline. Dumpster enclosures, bollard footings, wheel stops and curbing are placed so they do not obstruct the route. Where the route crosses a drive lane, we coordinate with truck courts and trailer yards and with stabilized parking lots so grades from each trade meet in the same place instead of arriving a quarter inch apart.
Which rules govern the route
The 2021 New Mexico Commercial Building Code, which adopts the 2021 International Building Code as amended and took effect July 14, 2023, sets the accessibility provisions that most plant permits are reviewed against. Federal accessibility standards apply on top of that for places of public accommodation and employment. Inspectors check slopes, widths, clear space and changes in level, and they can reject work on a few tenths of a percent of slope.
Existing buildings add their own wrinkles. The state publishes a separate Existing Building Code, and an alteration to an older plant can trigger accessibility upgrades to the route, entrance or restrooms. The 1992 renovation of the New Mexico State Capitol, which included accessibility improvements, shows how common it is for even landmark buildings to carry this work. When we start a project we ask the building department how the alteration will be treated and, where it is helpful, bring in our permitting and entitlements coordination team early.
Who relies on accessible site work
Plants that welcome visitors, auditors and clients, such as those in pharmaceutical and life sciences, tend to scrutinize entrances and parking more than those that do not. A clean, level, well-marked path to the front door is part of how the company presents itself. In Santa Fe, where employment is led by state government with roughly 15,000 jobs, many industrial users also serve public customers, which raises the visibility of accessibility.
Small-bay and flex properties hold several tenants with different visitor patterns, so the common route has to work for all of them. Office-area buildouts attached to a plant need the same discipline inside as the site concrete has outside, and we coordinate the transition at the door.
How we pour to tolerance
We begin by reviewing the grading plan against the accessibility drawings and calling out conflicts before the forms go up. Grade stakes include finished elevations for the critical points: landings, ramp tops and bottoms, door thresholds and the high point of the access aisle. The concrete finishing trade partners use digital levels on the wet concrete, and we check slope again before the final trowel pass while correction is still easy.
After the pour, we measure again, document the results with photos and readings, and fix anything out of tolerance. Where a small section fails, we cut and replace that panel rather than grinding or patching, because a ground surface wears quickly and attracts attention. The record we leave goes to the owner and the inspector as part of closeout.
Sequencing around paving, utilities and doors
Accessible concrete depends on other trades finishing first. The door threshold and finished floor elevation, which come from the industrial concrete floors package, have to be set. Underground utilities need to be in and tested before flatwork. Paving grades need to be known so the ramps tie to them. We hold a short coordination meeting before forming begins, because the cheapest time to resolve a one-inch mismatch is before the forms are set.
Weather affects the schedule at this elevation. Concrete has to be protected from freezing in cold weather and from rapid drying in the dry season, and we plan blankets, cure compounds and pour times accordingly. On occupied sites we phase the work so that at least one accessible route stays open, with temporary ramps or marked alternates in place.

Send us the site plan and the entrance layout. We will walk the path from stall to door, flag slopes and levels that need attention, and quote the concrete work to the standard an inspector will hold it to.
Common Questions
What slopes should I expect on an accessible route?
The standards set maximum running and cross slopes for walks, with steeper limits for ramps and tight limits for landings. The exact numbers are on the accessibility drawings, and our job is to build to them, not around them. We stake finished elevations and check with a digital level before the final finish.
How many accessible parking spaces does a small plant need?
The required count depends on the total number of spaces and the use, and the code gives a table that scales with the lot. A van-accessible stall with a wider aisle is required for some of them. We lay out the stalls on the approved plan and confirm the count with the building department if the lot changes during construction.
Can existing concrete walks be corrected without full replacement?
Sometimes. Small vertical changes can be ground or bridged with a beveled transition, but slope errors across a panel generally require removing and repouring it. We survey the existing route, mark what can be fixed in place, and give you a firm price for the rest.
Does a tenant improvement trigger site accessibility upgrades?
It can, depending on cost and scope. An alteration to a building may require an accessible route to the altered area, including the entrance and parking. We help owners understand the likely scope up front so the budget includes site work rather than discovering it at final inspection.
What do inspectors check first?
Entrance thresholds, ramp slopes, landing sizes, stall dimensions and the signs and markings at accessible stalls. They also check that nothing obstructs the route. We do a pre-inspection walk with a level and tape so the first official visit is routine.
