A 30 psf ground snow load and a 36 inch frost depth set the structure of every warehouse we build in Lakewood, and we put those numbers into the first sketch rather than the last. The City of Lakewood publishes its design loads in a permit handout, and the combination of snow, wind and frost drives roof joist spacing, footing depth and the cost of the slab edge. We read the document before we talk about layout.
The handout also lists the 2021 IBC, 2021 IRC, 2021 IFC, 2021 IEBC and 2023 NEC as adopted codes, with local amendments in Title 14 of the municipal code. That gives developers a single city document that states the editions in one place. We use it as the baseline for each Lakewood proposal and confirm any amendments with plan review before pricing finishes.
Buildings here tend to be modest in footprint and rich in use. We deliver tilt-wall and pre-engineered flex light industrial buildings, small distribution shells and expansions that sit near the Denver Federal Center, along the W Line and close to the I-70 and State Highway 470 interchanges.
Reading the city loads into the structure
Lakewood's handout lists a 36 inch frost depth, a 30 psf non-reducible ground snow load, a 30 psf minimum roof snow/live load, wind Exposure C and Climate Zone 5. Each number touches a different part of the building. Frost depth sets the footing and the slab edge, the snow load drives the roof structure and rooftop-unit curbs, and Exposure C raises wind pressures on tall panels and open dock doors.
Climate Zone 5 shapes the envelope. Insulation, air barrier and glazing choices follow, and cold-storage or conditioned bays add more. We bring the mechanical engineer into the discussion before pricing, since a conditioned warehouse changes roof loading and utility sizing. These items reach the budget in preconstruction rather than as a change order.
What a Lakewood building package includes
The standard package covers grading and utilities, footings, slab, panels or a pre-engineered frame, the roof, an ESFR sprinkler design coordinated with the rack layout and the dock package. On smaller buildings we also include the office finish, restrooms and a small mezzanine if the tenant requires it. Each element is priced as a separate line so a developer can compare alternates.
We pay attention to the interface between the roof and the snow load. Parapets, rooftop-unit placement and drift zones change where snow accumulates, and a parapet that works on a flat site can create a drift on a stepped one. Our engineers lay out the roof with the drift question in mind.
Light industrial, medical supply and government-adjacent users
The Denver Federal Center in Lakewood covers 623 acres with 44 buildings, nearly 8,000 employees (7,777 in the EPA profile) and 28 federal agencies. The site and its neighbors create steady demand for storage, contractor yards and logistics support. We build warehouses and small flex buildings that serve those users, as well as contractors who need shop space with a dock and a few offices.
St. Anthony Hospital built a medical campus on 50 acres sold from the Federal Center, which opened in 2011 with about 1,500 employees, and an RTD light rail station opened in 2013 on another former part of the site. Medical supply and equipment distributors benefit from short drives to those campuses. For them, we focus on temperature-conditioned storage and secure receiving.
Working next to a cleanup site and a busy corridor
Cleanup of the former ordnance plant site at the Denver Federal Center is overseen by the Colorado Department of Public Health and Environment. A parcel near that land calls for an environmental review before design is final and an on-site plan for how to handle unexpected soil conditions. We prepare that plan with the owner's consultant so workers know what to do and whom to call.
Lakewood is crossed by Interstate 70, U.S. 6, U.S. 40 (West Colfax) and State Highway 470 on its western edge, with U.S. 285 along the southern edge. Those are busy corridors. Our site safety program covers traffic control at entrances, pedestrian separation from deliveries and daily crane and rigging checks.
What moves a Lakewood budget
The big movers are the structural loads, which drive steel tonnage and footing depth, and utility capacity at the site. We price the roof structure with the 30 psf snow load in view, which can add weight compared to a milder site. Rooftop units are another driver, since added weight needs added steel.
We also look at the value of speed. If a tenant's lease clock is running, a pre-engineered building on a fast slab can cut weeks off the calendar. If durability and appearance matter more, tilt-wall construction may justify a modest premium. We show both options side by side so the owner decides with numbers, which is the conversation we most often have with developers and REITs weighing a portfolio of small buildings.
Sequencing around frost and snow
Colorado winters allow work, but the plan must account for it. We schedule footings and the slab to avoid freezing temperatures where possible, and when that is not possible we use blankets, heated enclosures and accelerated mixes. A realistic winter schedule is a few days longer than a summer one, and we say so up front.
The W Line, which opened April 26, 2013 with seven stations in the city, gives workers a transit option, and tenants who rely on shift labor appreciate it. We keep the schedule of dock equipment, racking and sprinkler tie-ins coordinated so the tenant can start moving in as soon as the certificate of occupancy arrives. Operators relocating from Golden or Wheat Ridge often want their new building running within a single shift change, and the plan is built.

Share the parcel, the target square footage and your required clear height. We will return a budget built on Lakewood's published design loads, a code path and a schedule that holds your lease date.
Common Questions
What snow load should we design for in Lakewood?
The city handout lists a 30 psf non-reducible ground snow load and a 30 psf minimum roof snow/live load. Those are the minimums, and drift and unbalanced conditions can raise them locally. We design the roof structure and rooftop-unit supports to those numbers and confirm any local amendments before pricing.
Which codes govern a new warehouse in Lakewood?
The City of Lakewood permit handout lists the 2021 IBC, 2021 IRC, 2021 IFC, 2021 IEBC and 2023 NEC, with local amendments in Title 14 of the municipal code. We use it as our baseline and verify with plan review, since amendments can change a detail late in design.
How deep do the footings have to be?
The handout lists a 36 inch frost depth, so exterior footings and slab edges are set below that depth or protected. The geotechnical report may require deeper foundations or over-excavation depending on the soil. We carry both in the budget until the report arrives.
Can we build near the Denver Federal Center?
Yes, many users do. Cleanup of the former ordnance plant site is overseen by the Colorado Department of Public Health and Environment, so we check the parcel's history and the reports available before design. If the review is clean, construction is routine; if not, we price the mitigation.
What does a flex building cost to deliver compared with a distribution shell?
A flex building generally carries more office finish and more mechanical work per square foot, while a shell carries more concrete and dock equipment. The comparison depends on the tenant mix and clear height. We price both on the same site and let the difference guide the decision.
