Secure, badged campuses change how a builder staffs and sequences a job, and Littleton has the kind of aerospace and technology campus where that matters. We plan these projects around access control first: who is cleared to be on site, where materials are inspected, which areas are off limits to which trades, and how the owner's security office approves a worker before the first shift. The building schedule sits behind the security schedule.
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. We cite it as a measure of what a controlled campus asks of a construction team: orientation, escorted deliveries, laydown yards inside or outside the fence, and trade coordination at a scale where one late subcontractor delays everyone behind it. We carry the same discipline to smaller assembly, test and office-attached high-bay projects.
Highway access is solid. U.S. 85 is a through route, State Highways 75 and 88 and C-470 run through Littleton, and the city lies on the South Platte River at 5,397 feet elevation. At that elevation we apply altitude derating to combustion equipment and rooftop units at submittal, and the river proximity puts groundwater and floodplain checks at the head of the geotechnical scope.
Badging, escorts and controlled access
On a controlled campus the safety plan and the security plan are one document. We submit worker lists in the format the owner requires, hold orientation sessions before mobilization, and agree on escort rules for deliveries that cannot be cleared at the gate. Photography, devices and material storage rules are written into the subcontractor package, so every trade enters with the same expectations.
We keep a daily log of who was on site and in which areas, and we correct any breach immediately with the owner's security lead. The same log supports the turnover package and shows the owner that the access plan worked as designed.
High-bay assembly and test space
The scopes that suit a technology or aerospace campus are high-bay crane-ready buildings, assembly floors with vibration and flatness limits, integration labs and test cells, and the office and support space attached to them. Each is a coordination problem between structure, slab, utilities and the equipment vendor.
We establish flatness and levelness targets with the owner's equipment engineer, design the slab thickness and reinforcement to the specified loads, and set embeds for crane rails, test fixtures and anchor bolts with surveyed accuracy. Where the owner needs a clean environment, we specify construction-phase dust control and protect finished surfaces until turnover.
Adopted code and local amendments
Littleton's building division lists the 2024 International Building Code as an adopted code, with local amendments in the municipal code. We read the amendments before the code analysis is written, because local changes often affect fire-resistance ratings, occupancy separations and accessibility details. The code analysis states the adopted edition, the amendments and the date they were confirmed.
Because Littleton is the Arapahoe County seat, with small portions extending into Jefferson and Douglas counties, a parcel near the boundary may fall under a different jurisdiction than the owner assumes. We confirm which authority has jurisdiction over the parcel, utilities and fire protection before design starts.
Aerospace and technology users
The industrial users in the area include aerospace suppliers, electronics assemblers, instrument makers and test firms. Many are advanced manufacturing operations with tight cleanliness, vibration and environmental requirements, small production runs and high-value equipment that must be protected during the work.
We serve them with a manufacturing plant approach: stable slabs, clean construction practices, early utility coordination and a commissioning plan. The owner's engineers write the performance criteria, and we verify them with measured results.
Commissioning as the critical path
On technical buildings, commissioning, not framing, tends to set the occupancy date. We schedule the commissioning, turnover and closeout sequence from the beginning: system start-up, functional tests, controls verification, air and water balancing, training and the turnover package. The commissioning agent sees the schedule at every meeting.
We also protect the long-lead list: switchgear, chillers, air handlers, process cooling and the generator. Each item has an order date, a delivery date and a named person responsible, and we raise any slip at the first sign.
What drives cost on a technical campus project
Cost on this kind of work follows the equipment more than the square footage. A high-bay assembly floor with crane rails, a test cell with a reinforced foundation, or a clean room with redundant air handling carries a cost per square foot well above a plain warehouse. We build the estimate from the owner's equipment list and the performance criteria, not from a generic rate.
Security adds another layer: escorted deliveries, inspection of materials, restricted work hours and the labor lost to badging and gate delays. We price these items explicitly. The owner can then choose between a longer duration with fewer constraints, or a shorter one with higher premium labor.
Security, fencing and neighbors
Secure sites need perimeter control. We coordinate fencing and security integration with the owner's security contractor: gates, access readers, cameras, lighting and conduit routes are coordinated on one drawing so that nothing is trenched twice.
Owners comparing sites will also consider Centennial and Lakewood, and we can compare their adopted codes, utility service and access routes in a short memo.
Send the access rules and the program
Send the access rules, the equipment list and the target occupancy date. We will return a schedule that shows the security steps, the long-lead items and the commissioning sequence.
Common Questions
How do you handle badging for a secure campus?
We submit worker lists in the owner's format ahead of mobilization, provide the information the security office needs and hold an orientation. New workers are not allowed on site until cleared, and we plan labor loading with the lead time in mind.
Which code edition applies to a new building?
The building division lists the 2024 International Building Code as an adopted code, with local amendments in the municipal code. We confirm the edition and the amendments in writing at the start of design, since a project that straddles an adoption date can fall under either.
What flatness can you achieve on a high-bay slab?
We set the target with the equipment engineer, then plan the base, reinforcement, pour sequence and finishing method to reach it, and we measure the result. Flatness depends on the design and the placement, so we agree on the measurement method before the pour.
Does the river affect construction?
It can. Proximity to the South Platte means we check groundwater depth and floodplain status early, and the results can change the foundation type and the finished floor elevation.
Can work happen in an occupied lab or assembly area?
Yes, if the occupant can define clean zones, vibration limits and shutdown windows. We use dust barriers, negative air where required and vibration monitoring, and we schedule disruptive tasks for off-hours.
