Traffic counts lease a retail center before a single finish is chosen. A pad site with freeway frontage and a signalized entry sells at a premium, and the builder's job is to turn that frontage into a delivered building without losing the lease date. We build shopping centers, strips with a grocery tenant and big-box pads in Colorado, and we price them in the metrics developers use: building area per pad, parking stalls per thousand square feet, dock doors on the rear court and weeks to a tenant turnover.
The Front Range has several examples of how big these sites get. A 2022 report described a Highway 60 and I-25 project in Johnstown planned for more than 1,000 housing units and more than 1 million square feet of retail with Murdoch's committed, at an interchange passing more than 99,000 vehicles daily. The Ridge at Johnstown is a 265-acre master-planned mixed-use site with 90 acres of I-25 frontage and about 100,000 vehicles per day of freeway visibility. At that scale, the shopping center is a phased infrastructure program, not a single building.
Because we spend our days on large slabs and big truck courts, retail logistics comes naturally. The rear of a grocery store is a small distribution building, and it deserves the same attention as the front.
Phase the site, protect the open dates
A retail center opens in pieces. The lead tenant wants its date, the in-line shops want theirs, and each pad owner wants the road in before they start. We plan the site as a sequence of delivery packages: mass grading and utilities for the whole parcel, then the lead tenant's shell, then shops, then pads. Backbone infrastructure goes in first so every later package builds against finished curb, storm and water.
We keep the site open and safe while it builds out. Early tenants are trading while we are still pouring the next phase, so we separate construction traffic from customer traffic, put temporary fencing and signage in place, and schedule noisy work around trading hours. It is the discipline we bring to every phased job, from warehouse expansion to new retail.
Where Front Range retail is getting built
Retail follows rooftops and interchanges. Centerra is a commercial hub at the I-25 and US 34 interchange, shared by Loveland and Johnstown, with shopping centers, a mall, a medical center and the Blue Arena. Firestone annexed the Turner Commons site at the northwest corner of I-25 and Firestone Boulevard in 2012 and zoned it for regional retail and commercial uses. Farther south, Orchard Town Center, an outdoor mall with more than 90 specialty retailers, is located at I-25 and 144th Avenue in Westminster, and FlatIron Crossing in Broomfield opened August 11, 2000 and has about 1,467,566 square feet of gross leasable area.
What that tells a developer is simple: mature retail sits on the interstate, and new retail is moving up the I-25 corridor toward the next set of interchanges. We build in the established nodes and the emerging ones, and we adapt the program to each. An outdoor lifestyle center wants more site finish and landscape than a power center, which wants more paving, more stalls and a bigger rear court.
Shell, pad and site package
For an in-line shopping center, we price the shell as a tilt-wall or masonry and steel structure with a storefront-ready front elevation, a code-compliant demising system and a rear service corridor. Tenants get a shell with utilities stubbed in: electrical service, domestic water, sanitary and a fire sprinkler main. Pad sites for restaurants, banks and fuel get their own utility taps and a paved pad.
The rear court is where our warehouse experience pays off. A grocery or big-box rear court needs truck-turning geometry for a 53-foot trailer, a dock or a flush door, a compactor pad and an apron that does not drain across the delivery lane. See our truck court and trailer yard work for how we size those, and our site utilities package for how we sequence the underground.
What swings the number on a retail center
Site work leads. Mass grading, detention, retaining walls and utility extensions often cost as much as a shell on a large parcel, and they are the part with the fewest alternates. Next is parking. A center with a high stall ratio uses more asphalt, more lighting and more storm capacity, and in a tight infill parcel the ratio can push the design toward a structure. For that, see our parking structure page.
Finishes come last. Storefront systems, canopies and signage bands drive the look and the lease rate. We give developers a clear split between base shell and upgraded elevation, so they can decide how much façade to build ahead of tenants and how much to leave for the tenant's brand.
Hitting tenant turnover dates
Retail leases carry rent commencement dates, and a late shell costs the owner every day. We build the schedule backward from the earliest tenant turnover: when the tenant needs the keys, when their contractor needs 8 to 12 weeks for fixtures, when the shell must be dried in, and when the underground must be done. Long-lead items such as storefront, rooftop units and electrical gear get purchase orders at permit.
For multi-building centers, we propose to turn over the lead tenant first, then shops in sequence, then pads. Each handoff comes with a punch list, a set of as-builts and an inspection record, so tenants' contractors are not guessing about slab thickness or conduit locations.
Who we build retail for
Developers and REITs lead the list, and they hire us for repeatable shell packages across several sites, as described under developers and REITs. Retailers with their own prototypes hire us for a single store or a small group. And chains whose supply chain matters, such as grocers and big-box operators, come to us for the connection between store and distribution network, which we cover in retail distribution.
Many centers also include a hotel or self-storage pad on the same parcel. We look at hotel and self-storage facility pads in the same master plan, so utilities and access are built once.

Send us the site plan and the target tenant list. We will return a phased budget, a utility sequence and a schedule keyed to your first turnover date.
Common Questions
Should we build the whole shopping center in one go or phase it?
It depends on pre-leasing. If a lead tenant is signed and shops are likely to follow, we install the full backbone infrastructure and build the lead tenant's building and the first shop building. We hold pads and later buildings until leases are in place. This keeps the owner's cash tied to leased space and avoids a half-empty center.
How much of the budget is site work versus buildings?
On a large parcel, site work can rival the shell cost. Grading, detention, utilities and paving all scale with acreage, and there is little to value-engineer in them. We show the owner a split so they can see what moves with building size and what moves with land.
What code does a retail center in my town follow?
Commercial codes in Colorado are adopted city by city and county by county, and the Home Builders Association of Metro Denver tracker dated January 20, 2026 shows 2018, 2021 and 2024 I-codes in use at the same time. We confirm the edition and any local amendments with the building department at the start.
Can you build the rear dock court for a grocery tenant?
Yes. We design the court for 53-foot trailers, with turning room, a compactor pad and drainage that does not cross the delivery lane. We supervise and inspect the concrete work closely, so the court stays flat and durable under heavy truck traffic.
How do you keep tenants open during construction?
We separate construction and customer traffic, fence work zones, post signage and schedule noisy work outside trading hours. A weekly coordination call with the owner and tenants flags conflicts early.
