Manufacturers that ship from Longmont need a building that works as hard as the line inside it. We build manufacturing support, warehouse and distribution space in the city, with floors that carry equipment, power and compressed air that arrive on time and docks that let finished goods leave on schedule. Longmont's largest employers include a data storage manufacturer, a school district, the city, a communications technology firm and a hospital, and that mix keeps suppliers and contractors busy.
According to Longmont's 2020 annual comprehensive financial report, as summarized on Wikipedia, those employers are St. Vrain Valley Schools (3,543 employees), the City of Longmont (1,625), Seagate Technology (1,430), Intrado (755) and Longmont United Hospital (671). Seagate and Intrado signal technology and production activity, and the suppliers around them need nearby space to stage components, store consumables and ship product.
Highways connect the city to its neighbors. U.S. 287 (Main Street) runs through the center of Longmont, 16 miles north to Loveland and 34 miles south to downtown Denver, and State Highway 119 passes south of downtown, 15 miles southwest to Boulder and 5 miles east to I-25. We use those distances to help owners compare delivery times to customers.
Manufacturers, suppliers and local distributors
Manufacturing and distribution users value a building that combines production support, storage and shipping. A typical program includes a clean production area, a warehouse zone with 24 to 32 feet of clear height and a dock package matched to the product. We coordinate power, compressed air, process piping and exhaust with the structure.
Component suppliers and contract manufacturers, who often serve larger operations nearby, usually want flexible space that can be reconfigured. We design with column spacing, floor loads and utility stubs that accept new equipment. This flexibility lets a tenant add a line without demolition.
Floors and structure that carry equipment
In manufacturing, the slab is part of the machine. We supervise and inspect the industrial concrete floor, so we control thickness, reinforcement, joint layout, flatness and curing. We coordinate with equipment vendors on mounting locations, trenches and pits, and we embed sleeves and conduits before the pour. A late change in a trench location after the slab is poured is expensive, and we work to avoid it.
We also coordinate the trade partners who erect tilt-wall panels and set structural steel. On a manufacturing building, the structure often includes crane rails, heavy mechanical platforms or roof loads that exceed a typical warehouse. We design those into the frame at the start and price them separately so the owner sees the impact.
Biotech investment and land near the airport
AstraZeneca announced on October 10, 2016 that it paid $64.5 million for 159 acres of vacant land just west of Amgen's Longmont campus to support its Boulder operations. The announcement is several years old, but it shows how large life science and manufacturing users have approached the Longmont area, and why suppliers and logistics providers need buildings nearby.
Vance Brand Airport, city-owned and about three nautical miles southwest of downtown Longmont, has a single concrete runway (11/29) measuring 4,800 by 75 feet. The City of Longmont says the airport has more than 40 acres of land on the southwest side available for development or expansion. Airport-adjacent parcels attract aviation services, hangars and light industrial users who value a quiet, uncongested setting.
Confirm the edition, then design
The HBA of Metro Denver code tracker dated January 20, 2026 listed Longmont as enforcing the 2021 IBC, with adoption of the 2024 I-Codes expected April 1, 2026. The tracker is not an official source, so we obtain written confirmation from the city before finalizing structural and life-safety drawings. If the expected date has passed, the new edition may apply.
Industrial users have additional approvals. Process exhaust, chemical storage, wastewater and hazardous materials may trigger fire code review and separate permits. We ask the tenant's environmental, health and safety staff to share their requirements in the first month and then fold them into the building design. Saving that conversation until after permit submittal is the most common cause of delay.
Plants, warehouses and mixed buildings
We build manufacturing plants of 30,000 to 150,000 square feet, warehouses for regional distribution and mixed-use industrial buildings that combine production, storage and offices. The tilt-wall method works for most of them, while pre-engineered buildings suit tenants who need speed or future expansion.
We also build support facilities: maintenance shops, employee amenities, outdoor storage and truck courts. Each has its own details, from wash bays to lunchrooms, and we coordinate them with the main building so the site works as a whole.
Utilities, power and the pace of a growing city
Industrial projects stand or fall on utilities. Power capacity, gas, water, sewer and telecommunications must be confirmed with each provider before the design is final. We ask for will-serve letters and lead times on transformers and switchgear, since those items can take longer than the building.
Longmont continues to grow, and new development competes for contractors and inspectors. We plan for that by locking in subcontractors early, ordering long-lead items at once and keeping a steady schedule of coordination meetings. When the market is busy, planning is the only protection against delay. Users relocating from Erie or Lafayette can keep the same project team.
Where manufacturing budgets move
The big drivers are the slab, the electrical service and process utilities. A slab designed for heavy equipment can cost a significant premium over a standard warehouse floor, and a larger electrical service adds gear, trenching and utility fees. We list those items as separate lines so owners can see how each requirement affects the total.
We also help owners think about phasing. A building that can be built in two parts, with the shell, utilities and half of the process area first, gives a company a way to start production sooner and add capacity later. That approach is common with Boulder companies that need production space beyond a startup suite.
Send the process and the power load
Tell us what you make, the equipment loads, the utilities required and the building size. We will return a budget with the slab and electrical service priced separately, a code review and a schedule.
Common Questions
What are the key highways for a Longmont plant?
U.S. 287 (Main Street) runs through the center of the city, 16 miles north to Loveland and 34 miles south to downtown Denver. State Highway 119 passes south of downtown, 15 miles southwest to Boulder and 5 miles east to I-25. Trucks typically use Highway 119 to reach the interstate.
Which building code applies in Longmont?
A January 2026 tracker listed the 2021 IBC with the 2024 I-Codes expected April 1, 2026. The tracker is not an official source, so we confirm with the city. We design to the confirmed edition and keep alternates ready.
Can we build near Vance Brand Airport?
The City of Longmont says the airport has more than 40 acres on the southwest side available for development or expansion. Use, access and lease terms are set by the city. We help evaluate the site and build hangars or light industrial buildings once the terms are clear.
How should we plan the slab for heavy equipment?
We start with equipment weights, mounting locations and trench needs. Then we design thickness, reinforcement and joints, and we embed sleeves and conduits before the pour. Late changes after the pour are costly.
How long do electrical lead times run?
Switchgear and transformers can take many months, so we order them as soon as the design allows. We confirm lead times with the utility and the supplier during preconstruction and track them weekly.
Can the building be phased?
Yes. We can build the shell and utilities for the full footprint and complete the interior in stages. That allows production to start earlier and capacity to grow later.
