Controlled-access distribution and light industrial buildings suit Littleton, where a large aerospace employer on its Waterton Canyon campus creates demand for secure supply space nearby. We build shells with badge-controlled docks, fenced yards, tight sightlines and the electrical and telecom capacity that those users require, and we do it for developers who want a building that leases to a corporate tenant rather than a general warehouse user.
The employer base explains the demand. Lockheed Martin began a $350 million, 266,000 square foot Gateway Center on its Waterton Canyon campus in Littleton in 2017, with about 1,500 construction contractors over a three-year build. A project of that size shows how a large employer pulls construction activity, suppliers and ancillary space into a city. Suppliers want to be near the campus, and developers want product ready for them.
Access helps too. U.S. 85, State Highways 75 and 88 and C-470 run through Littleton, which lies on the South Platte River at 5,397 feet. A fleet based here can reach the south metro, the southwest foothills and the interstate network with a short run.
Secure, serviceable, and ready for the tenant improvements
A secure tenant generally wants an enclosed, monitored perimeter, a single controlled entrance, a loading dock that is separated from the office and a yard with fencing and lighting. We design these items into the base building so the tenant improvement does not tear them out. Conduit for access control, camera mounting points and generator pads are cheap during construction and expensive after.
We also confirm early who will hold the security requirements, since some tenants impose them by contract. Where details are confidential, we sign the appropriate nondisclosure terms and limit the drawing set to the people who need it. That keeps the project moving without making the developer guess at what the tenant will want.
Littleton's code and a city that crosses county lines
Littleton's building division lists the 2024 International Building Code as an adopted code, with local amendments in the municipal code. Littleton is the Arapahoe County seat, with small portions extending into Jefferson and Douglas counties, which are served by Jeffco Public Schools and Douglas County School District RE-1. For a developer, that boundary pattern is a reminder to confirm the exact jurisdiction for the parcel, since the permitting authority, code and fees follow the parcel.
Colorado law adds an energy layer. HB22-1362 requires any county or municipality that updates a building code on or after July 1, 2023 to adopt an energy code with equivalent or better performance than the 2021 IECC, and from July 1, 2026 the benchmark becomes the state model low energy and carbon code. With a 2024 code in place, we assume a modern envelope, lighting and electric-ready package and price it in the first budget.
Why suppliers cluster near large employers
A large campus consumes parts, tooling, electronics and services, and many of those flow through nearby warehouses. A supplier that stores inventory a few miles from the customer can deliver on short notice and reduce its own shipping cost. That is the logic behind small and mid-size distribution buildings near employment centers.
When a developer evaluates such a site, we help compare it with alternatives south of the city. A parcel in Centennial near the airport has a different tenant profile, and a parcel in Lone Tree sits closer to the I-25 and C-470 interchange. We price each building in the same format so the choice is based on rent, not guesswork.
Heavier floors and taller buildings for technical users
Not every technical tenant needs a standard warehouse. Some want a high-bay, crane-ready building for assembly or test operations, with a taller clear height and structure designed for a bridge crane. Others need industrial concrete floors with a specific flatness, vibration performance or chemical resistance. We write those requirements into the structural and slab package.
Heavy loads change the foundation, and sensitive equipment changes the floor. We coordinate with the tenant's equipment supplier before the slab is poured, since coring a slab later damages both the floor and the schedule. A single set of requirements shared among engineers prevents.
Sequencing a technical shell
Technical tenants buy long-lead equipment on their own schedule, and the base building has to meet that clock. Generators, switchgear, rooftop units and high-capacity transformers often outlast the structure in lead time, so we identify them in preconstruction and ask the tenant which items they will furnish and which we should buy. The schedule shows the electrical service date as a milestone, since a finished building without power is not occupied.
The office component deserves its own look. A technical tenant may need more than the office area a pure warehouse carries, as office area, with a lab-quality mechanical system and acoustic separation. We build that as a defined scope inside the shell, with its own inspection milestones, so it does not delay the warehouse side of the permit or the certificate of occupancy for the rest of the building.
Working next to operating campuses
Construction next to an operating secure campus raises its own rules. We control contractor access with badges or escorts where required, keep photography off the work zone unless approved and maintain clear separation between site crews and the tenant's staff. Truck traffic follows a defined route, and deliveries are scheduled so queues never block a public road.
Standard jobsite safety applies as well: fall protection during panel erection and roof work, trench safety, crane lift plans and daily briefings. Our superintendent reviews each lift and makes sure the ground can carry the crane. For developers and REITs who hold the building long term, a clean safety record and well-documented project help when the asset is financed or sold.

Common Questions
What is Littleton's adopted building code?
The building division lists the 2024 International Building Code with local amendments. We confirm the current amendments with the division at the start of design.
Why does the county boundary matter?
Littleton is the Arapahoe County seat, and small portions of the city extend into Jefferson and Douglas counties. We verify which jurisdiction governs the parcel so the code, fees and review process are right.
Can you build to a tenant's security requirements?
Yes. We build to the criteria the tenant provides, and we can work under confidentiality terms. We usually include conduit, power and structural provisions in the base building so the tenant's security contractor can install equipment without core drilling.
How do you coordinate long-lead electrical gear?
We list generators, switchgear and transformers at the start, ask the utility for its service date and place orders as soon as the design allows. The schedule shows the power date as a milestone alongside dry-in and the certificate of occupancy, so the tenant knows when equipment can start up.
Is a high-bay crane-ready building possible?
Yes, if the structure is designed for it. The crane capacity, runway, column spacing and clear height drive the design, and we coordinate with the crane supplier early.
