Roof snow load, not span, is what sizes a metal building frame on the Front Range, and the number changes with the jurisdiction. Lakewood publishes a 30 psf non-reducible ground snow load and a 36 inch frost depth in its design-loads handout. Glenwood Springs sets a minimum of 50 psf and scales it with elevation. A frame priced from the wrong city sheet arrives from the manufacturer with the wrong columns, and the only fix is a reorder.
We build pre-engineered metal buildings as the owner's general contractor or as the erector and foundation builder under a design-build arrangement. The package begins with the manufacturer's reactions, which tell us what the footings must resist, and ends with the building envelope closed, insulated and signed off. Between those points sits civil, concrete and utility work that the metal building supplier does not provide. That is where most schedule and budget problems on a PEMB job originate, and it is the part we plan hardest.
Metal buildings suit shops, warehouses, equipment storage and light-assembly plants where clear span, speed and a lower first cost matter more than panel mass. When a buyer needs a heavier wall or a larger floor plate, we compare it honestly against tilt-wall construction and recommend whichever fits the use.
Why PEMB demand tracks site conditions
Colorado's weather sets the building specification before the program does. Denver ranks 10th among U.S. areas of at least 50,000 people for hailstorm risk and has had three of the ten costliest U.S. hailstorms, so roof panel gauge, finish and warranty terms are not cosmetic. We ask the manufacturer for the hail rating on the roof system, confirm what the insurer will accept, and write the answer into the submittal log so the building does not reach turnover with an uninsurable roof.
Industrial parks are also built for this building type. Great Western Industrial Park in Windsor is described as a 3,000-acre master-planned park with dual rail interchanges and building sizes from 60,000 to 1,000,000 square feet, and parks of that kind favor an efficient frame at the small end of the range. Operators looking in the Windsor area or along the I-25 corridor should expect competing lots, and a metal building can be erected quickly once its foundation is in.
What we manage under the building
The foundation determines whether the frame sits right, so we schedule, supervise and inspect excavation, forming, rebar and concrete placement for footings, piers and slab. Anchor bolts and rods are set with templates and surveyed before the pour, because a bolt that is a half inch out of position becomes a field modification that the manufacturer must approve. We check every bolt group against the frame drawings and keep the survey record with the closeout set.
Slab work follows the same coordinated schedule. We place the floor with the joint layout, vapor barrier and reinforcement the geotechnical report supports and finish it to the flatness your equipment needs. Where soils are expansive, we follow the engineered foundation approach in our deep foundations work rather than relying on shallow spread footings, and we discuss moisture conditioning of the subgrade before the first footing is excavated.
The scope from pad to occupancy
The scope begins with the geotechnical report and a reaction check, then moves to site grading, underground utilities and the foundation. Frame erection starts after concrete reaches the strength the manufacturer requires. We receive and inventory the steel against the packing list, set primary frames, install purlins and girts, then hang roof and wall panels with the insulation system specified for the use. Overhead doors, personnel doors, louvers, skylights and rooftop equipment curbs follow.
Finish scope depends on what the building will do. A shop will need slab drains, compressed-air piping and exhaust, which we coordinate with the electrical service and the maintenance shop and service bay fit-out. A light-assembly building needs mezzanine columns coordinated with the frame, and we cover that in light manufacturing and flex work. We keep a single scope matrix that lists who supplies and who installs each item.
Erection safety and weather
Metal building frames go up fast, and speed is where erection injuries concentrate. We plan the sequence with the erection engineer, brace each frame as it is set, and do not release a crane or lift from a bay until the bracing the manufacturer specifies is in. Wind is the daily constraint on the plains. We set a go or no-go wind limit with the crane operator before the shift, because a standing frame with sheeting half installed catches more wind than a finished building.
Roof access and fall protection are planned from the first panel. We install temporary lines, use nets or controlled decking zones as the work requires, and keep material laydown away from overhead operations. On sites with active traffic, we separate the haul route from the erection zone with barriers and flaggers, and we keep the access arrangements consistent with the phasing used in occupied site work.
Where the building meets the rest of the site
A metal building is rarely the only item on the permit. Truck circulation, trailer storage, fire water, stormwater and security all follow. Our truck courts and trailer yards work sizes the pavement for the fleet you run, and our fencing and security integration team brings gates, access control and lighting into the same drawings. Buyers who bundle the pad, the building and the yard under one contract avoid the interface disputes that occur when each trade is bid separately.
Several end uses have their own building-type pages. Operators buying a metal building for dry storage can read about self-storage facilities, and automotive buyers weigh the same frame against the requirements in automotive and EV work, where service bays and floor drains change the plan.
What moves the price
The frame is typically the cheapest line per square foot in the package, and the site work around it is where budgets stretch. Footing size follows frame reactions and soil bearing. Insulation and liner choices follow the occupancy and the energy code the jurisdiction has adopted; Colorado's HB22-1362 requires any local government that updates its building code on or after July 1, 2023 to adopt an energy code at least as stringent as the 2021 IECC, so the envelope you buy may be tighter than the sample on the manufacturer's website.
Delivery is the third driver. Primary steel comes with a manufacturer lead time, and a late release means standing crew costs. We lock the frame order against the foundation schedule and add a dated hold point in the schedule where the manufacturer confirms ship dates.
Get the frame priced against the right jurisdiction
Send us the parcel, the program and the manufacturer if you have one. We will confirm the load criteria, price the foundation and site work, and give you a schedule that shows the steel release, erection and turnover dates.
Common Questions
Is a metal building cheaper than tilt-wall in Colorado?
Usually for smaller footprints and lighter wall requirements, yes. As the building grows or the wall needs impact resistance and thermal mass, tilt-wall closes the gap. The decision also depends on the clear height, the crane or racking plan and the jurisdiction. We price both options at concept stage when the program allows, so the choice is made against numbers.
Who is responsible for the anchor bolt layout?
The foundation builder places the bolts, and the manufacturer's drawings define the pattern. We use templates, survey every group before the pour and send the record to the manufacturer. A mismatch discovered after the frame arrives is expensive, so the survey is a hold point before concrete is placed.
Do we need a hail-rated roof?
Hail exposure in the Denver area is high enough that insurers and lenders often ask. Roof panel gauge, finish and the manufacturer's impact data matter. We request the rating in writing and check it against your insurance requirements before ordering.
How does the building code edition affect the frame?
Colorado jurisdictions adopt their own editions, and design loads come from local tables. The same plan can see different snow loads and different code requirements in neighboring cities. We confirm the edition and load criteria with the building department before the manufacturer starts the design.
Can a metal building be expanded later?
Yes, if it is planned that way. End walls can be built as bearing frames with removable cladding, and foundations can be sized for the next bay. We note the expansion direction in the foundation and utility drawings so a later bay does not require relocating a main or a transformer pad.
