Building for Manufacturers in Longmont, Niwot and Boulder

Process loads decide the building. Before a manufacturer in the Boulder Valley asks about square footage, it should be asking about power, water, compressed air, exhaust, floor loading and the path equipment takes to its final position, because those answers set the structure, the slab and the mechanical rooms. We build production, assembly, laboratory-adjacent and food and beverage facilities for owners who need a plant to run well on its first shift and still be adjustable on its tenth year.

The Boulder area's manufacturers are an unusual mix: aerospace and research suppliers, outdoor-industry makers, food and beverage producers and technology firms, many of whom run quiet precision processes rather than heavy industry. The buildings reflect that. Clean floors, controlled temperature, vibration limits and stable power often outweigh crane capacity, and we build to that spec. We also know that these owners ask hard questions about energy and environmental performance, and we give direct answers.

Where manufacturing sits in the valley

Longmont's 2022 data lists manufacturing as its largest industry at 7,188 people, ahead of professional, scientific and technical services and retail trade. A pharmaceutical maker announced in October 2016 that it had paid $64.5 million for 159 acres of vacant land beside a former campus in Longmont to support its Boulder operations, which signals the scale at which life sciences companies are willing to plan here.

Along State Highway 119 near Niwot there is a large IBM facility at the State Highway 52 intersection, and the state transportation department has planned a diamond interchange there to ease congestion. That interchange affects truck access and construction traffic for neighbors. In Gunbarrel, a 2016 article described a distribution building at 63rd Street and Spine Road and a building at 6060 Spine Road occupied by GE, though tenants may have changed since. We check any of these against current ownership before we plan around them.

Slabs, structure and the heavy early work

On a plant, the slab is part of the machine. We schedule, supervise and inspect concrete foundations and floors closely, so that flatness, joint layout, embedded conduit and equipment pads are placed by trade partners that know what the equipment will need. Heavy equipment often requires thickened slabs, deep pits or isolated foundations, and we coordinate those locations with the vendor drawings well before the pour.

Structure follows the process. A clear-span metal building suits many assembly operations, while tilt-wall or steel frames carry cranes, mezzanines and heavier loads. Our manufacturing facility construction group works with both, and when overhead handling is part of the process, we coordinate the runway beams and supports described in our crane building work. Specifying a slab for the equipment you will have in ten years can save a tear-out later, and we say so during design.

Energy code, exemptions and process loads in Boulder

Boulder's commercial energy code requires new buildings to be all-electric or to use other non-fossil sources, but it exempts large S-1 occupancies with constant vehicle traffic, labs and commercial cooking. Natural gas used under those exceptions must be offset by on-site renewables, except for commercial cooking, emergency generators and lab and industrial process loads. For a manufacturer, the distinction between a building load and a process load is the heart of the matter, and it should be decided with the engineer before design is fixed.

Other jurisdictions have their own rules. Longmont's city page lists the 2024 International Codes as adopted as of July 1, 2026, with a wildfire resiliency code, while a January 2026 regional tracker still listed Longmont on the 2021 edition with 2024 expected; the city page is newer, but we confirm the effective date with Building Inspection for every permit. Hazardous material storage, fire protection and air permits all add review time, and we put them on the schedule from the start. We also advise on manufacturing plant design basics for owners new to the area.

The buildings manufacturers ask us for

New owner-occupied plants are the largest jobs, but many of our manufacturing projects are expansions: a new bay on an existing building, a clean room added to a production floor, a utility yard for chillers and compressors or a dock addition for outbound freight. We plan these so that the existing operation continues, with temporary walls, dust control and shutdown windows for the tie-ins.

For food and beverage producers, the work includes sanitary floors, drains and wall finishes, along with refrigeration and hygienic design; our food and beverage processing work is organized around those details. Tenants in multi-tenant buildings often ask for a small production area within an office or flex space, and we price those as tenant improvements, which can be a good first step for a new venture.

Getting equipment in and production running

Manufacturing schedules turn on the equipment, which may arrive in pieces from several suppliers. We make a sequence for rigging and setting, with the building enclosed at the right moment so that equipment can enter before the last wall closes, and we hold temporary openings for large items. Utility turnovers, startup of process systems and commissioning each have their own milestones, and we track them separately from the building's certificate of occupancy.

Our work with owners of logistics and distribution space has taught us how to plan truck courts and dock sequencing, which matters to a plant that ships all day. We lay out receiving and shipping so that trucks do not cross in the yard, and we keep construction traffic off the owner's operating routes. For owners buying land from developers, our colleagues in commercial real estate can help evaluate parcels before purchase.

Services that usually go with a plant

Plants need site work as much as buildings do. Grading, utilities, stormwater detention, truck courts and parking are part of the same project, and doing them under one contract reduces gaps in responsibility. We bring civil work into the same schedule, and we coordinate with utility providers early on electrical service size, which can take months to arrange.

Preconstruction is where manufacturers get the most value from us. We help compare sites, estimate sitework and identify long-lead items such as transformers, switchgear and air handling units. When a plant has a floor that must be flat, the commercial concrete floors specification gets its own review, with a mockup if the owner wants one, so that tolerances are understood before production begins.

Working beside live production

Many expansions happen while a plant runs. We plan for it with separate entrances, controlled paths, lockout and tagout coordination with the owner's maintenance staff, and a daily check-in with the plant manager. Hot work, crane picks and shutdowns are scheduled with a written plan, and we keep site crews out of any area where production hazards are live.

Food and pharmaceutical customers may add requirements for contamination control, so we adapt our site practices: clean paths, covered materials, wash stations and a no-contact rule for open product. We log each of these, since auditors may ask later. Site crews are trained on the plant's own rules before they step on the floor, and we remove anyone who does not follow them.

Describe the process first

Send us the equipment list, the utilities it needs and the date production must start. We will return a building concept, a budget range and a schedule for permits and rigging.

Questions Owners Ask

How should we decide between a tilt-wall, steel and metal building for a plant?

Start with the process: crane loads, clear height, mezzanines, future expansion and the finish level inside. Metal buildings suit lighter assembly, tilt-wall gives durable envelope and good fire resistance, and steel frames carry heavy handling. We price the realistic options with your engineer and show the lifecycle consequences.

How do we plan for equipment that is delivered after the building is enclosed?

We either leave a temporary opening in the wall or roof, or sequence rigging before closing, depending on the equipment's size and delivery date. The plan is made with your equipment suppliers. We coordinate pit and foundation locations, utility stubs and rigging paths so the equipment fits where it is needed.

Can you build a clean room or a controlled environment?

Yes, and we start with the cleanliness class, pressure cascades and the air handling that supports them. Walls, ceilings, floors and penetrations are detailed for the standard, and we test and document performance during commissioning. A specialist subcontractor often supplies the cleanroom envelope, and we manage them.

Does Boulder's energy code apply to our process equipment?

It treats building loads and process loads differently. Natural gas used under the exceptions must be offset by on-site renewables except for commercial cooking, emergency generators and lab and industrial process loads. The line between the categories needs to be settled with the building department during design, and we help prepare that submission.
