Tight vacancy rewards the builder who can deliver a second building before the first is full. We build flex, shallow-bay and distribution space in Westminster's business parks, and we price phased projects so that a developer can start a first building and release the next on a trigger. Westminster's economic profile reports 30 business parks and over 18.7 million square feet of commercial space, including 3,582,581 rentable square feet of industrial and flex space at a 2.4 percent vacancy rate (CoStar, September 2023).
That figure is dated, and the market has moved since, but the pattern holds: tenants looking for 10,000 to 60,000 square feet find few options. Spec flex buildings and build-to-suit warehouse facilities for local employers have a ready audience. We help developers test absorption assumptions against tenant demand and set a delivery schedule that fits.
With I-25, U.S. 36 and U.S. 287 all in its network, Westminster draws users who also look at Broomfield and Thornton. We can price the same building in each to show the trade.
What drives cost for a business-park building
Business-park buildings are repeated products, so cost control comes from standardization. We use consistent panel widths, bay spacing and dock packages to reduce engineering and fabrication costs. Savings of a few dollars per square foot can add up across a multi-building park, and they matter most when rents are tight, which is the conversation we have most often with developers and REITs.
The big variables are site work and tenant finish. Park roads, utility extensions and detention are shared costs that should be allocated early. Tenant improvement allowances differ by user, and we price the base shell so that it can accept a range of finishes without demolition. We list those assumptions on the first page of the budget, so the owner can see which numbers are firm and which depend on a tenant that has not signed yet.
Employers that shape demand
Westminster's 2024 economic profile lists Ball Corporation (headquarters and manufacturing) with 1,335 employees, St. Anthony's North Hospital with 1,153, Maxar with 954 and Trimble with 850 as its top primary employers. Those firms draw suppliers, contractors and technology vendors who need nearby space for storage and light assembly, which suits manufacturing and distribution users.
Westminster is also served by I-25, U.S. 36, U.S. 287 and State Highways 95, 121 and 128, the Flatiron Flyer bus rapid transit line runs in the U.S. 36 express lanes, and the B Line (opened 2016) connects Westminster Station to Denver Union Station. For a company with employees in several directions, a site near that network lowers commute friction. We place employee parking, bike storage and transit access in the site plan.
Flex, shallow-bay and retail support
The most common products are flex light industrial buildings with 18 to 24 feet of clear height and front or rear loading. Shallow-bay designs of 120 to 150 feet deep suit small distributors and trade contractors. They can be subdivided into units of 5,000 to 15,000 square feet.
Orchard Town Center, an outdoor mall with more than 90 specialty retailers, is located at I-25 and 144th Avenue in Westminster. Retail and food-service operators near it need back-of-house storage and delivery space, and we design retail support warehouse space for them. These projects benefit from clean truck access and noise control.
Concrete and erection we manage closely
We schedule, supervise and inspect the concrete and the panel erection on most business-park buildings. That keeps the critical path under our control, which is important on multi-building schedules where one delay cascades. The trade partners we coordinate place footings, cast panels and pour slabs in a repeating sequence that improves with each building.
Close supervision also lets us hold quality on the slab. We specify a floor flatness suited to the user's equipment, place the concrete in logical sections and cure it properly. For tenants running forklifts or pallet jacks, a slab that rides smoothly improves productivity and reduces maintenance.
Phasing a park without stalling it
We build parks in phases that match the leasing pace. The first phase includes the main utilities and roads, then each building follows as demand allows. Foundations for the next building can be poured in advance, which shortens the schedule when a tenant signs.
Section 11-9-1(b)(1) of the Westminster municipal code adopts the International Building Code, 2021 Edition, Chapters 2 through 35, as the city's building code. We design to that edition, and we confirm any later amendments with the city before submittal. If the city moves to a newer edition, we adjust the design with minimal effect on the schedule.
Turning a lease into a certificate of occupancy
For build-to-suit work, the schedule runs from the signed lease. We release long-lead items at once, including dock doors, rooftop units and electrical gear. Then we sequence site work, slab and structure so the tenant can start racking and equipment installation as early as possible.
We hold a weekly call with the owner and tenant to resolve open issues. Closeout includes a punch list, training for the tenant's facility staff and a complete set of warranties and manuals. A clean turnover is as important as a fast one. When a tenant has a lease start that cannot move, we discuss a phased turnover in which the warehouse is released first and exterior paving or landscape finishes follow.
Send the park and the tenant profile
Tell us the site, the building count, the tenant mix and your target delivery date. We will return a phased budget, a code review for Westminster and a schedule linked to your leasing plan.
Common Questions
Is Westminster's industrial vacancy still tight?
The city's 2024 economic profile reported a 2.4 percent vacancy rate for industrial and flex space, citing CoStar data from September 2023. That figure is dated, so check current broker data. The pattern of limited supply for smaller tenants has encouraged both spec and build-to-suit development.
Which building code does the city use?
Section 11-9-1(b)(1) of the municipal code adopts the International Building Code, 2021 Edition, Chapters 2 through 35. We verify that against the city's current ordinances before each submittal and watch for amendments.
What is a realistic size for a flex building in a business park?
Many are 20,000 to 60,000 square feet and subdivide into units of 5,000 to 15,000 square feet. Clear height of 18 to 24 feet suits most small tenants. We test layouts against the demising plan so utilities and doors can be added without rework.
Can you phase a multi-building project?
Yes. We install the infrastructure for the full park and build each structure when leasing supports it. Pouring foundations early for the next building can save weeks when a tenant signs.
How does transit access affect warehouse design?
It affects labor draw and parking ratios. With the B Line, the Flatiron Flyer and several highways nearby, tenants can recruit across a wider area. We place employee entries, bike parking and shuttle stops where they work with the truck routes.
