One standard, every site. 70+ locations installed, including 60+ for a multi-state tire and automotive service brand. Engineered to ASCE 7-22 for your site. Sealed calculations in all 50 states. Engineering package in under one week.
Alpine Enclosure Systems supplies Alpine Citadel, a structural steel enclosure engineered per site to ASCE 7-22, with sealed calculations available in all 50 states and an engineering package in under one week. One standard detail covers every prototype, while each site's wind speed, exposure and foundation drive its own sealed calculations. Programs get one price nationwide.
Alpine has 70+ locations installed, including 60+ for a multi-state tire and automotive service brand, with trash and tire storage enclosures standardized across that program. Each site received its own layout and engineering, and each enclosure shipped as one kit tagged by bay. We describe programs without naming the client; ask us about the program when you call.
Tire storage and trash enclosures standardized across a 60+ location program; state shown only.
Your prototype drawings carry one Alpine Citadel detail: the same materials, finish color, gates and hardware at every location. Alpine then adapts each site: the layout to that site plan, the engineering to that address's wind speed, exposure and foundation, and the submittal to the local building department. The brand keeps one standard; each permit gets site-specific calculations.
Program pricing is set for the program rather than per region, and program kitting is organized by site and by release, so each store opening gets the right enclosure at the right time.
With one price nationwide, set for the program rather than per region. Typical installed cost for an 8 ft Alpine Citadel enclosure, excluding slab and site work, is $15,000–20,000 for a single and $21,000–30,000 for a double, including the engineering package for standard sizes. Program pricing for multi-site rollouts is available on request. Sites can be installed by Alpine, or supplied as kits for your contractors to install, with the installation guide and phone support. Supply-only kits are quoted per project.
Program kitting is organized by site and by release, so each store opening gets the right enclosure at the right time. Every kit holds one enclosure: parts tagged by bay, hardware packed with 10% extra, spare slats, a packing list and a layout drawing. Every gate is function-tested before it ships, so the site crew installs rather than adjusts.
CMU pricing moves with the region and the mason: 8 in grouted, reinforced CMU runs $14–32 per square foot across regions (Terrapin Construction Group, May 2026, citing RSMeans). Alpine Citadel installs in typically 1–2 days on a prepared slab, with fewer trades, no continuous wall footing and one price nationwide.
Steel vs CMU: cost, schedule and approvalsA detail they can drop into the prototype set. Alpine provides a CSI 3-part guide spec, CAD details for plan, elevation, gates, base plates and slab, standard-size sheets and a sample submittal package. For each site, Alpine returns the layout, bay schedule and engineering package in under one week, sealed where the jurisdiction requires it.
Resources and downloadsPrograms are built for brands that open or rebuild many similar sites: tire and automotive service, convenience stores and fuel, quick-service restaurants and drive-thru coffee, express car washes, and energy and data center sites that need equipment screening. Each has repeatable trash, tire or equipment enclosures, and each needs the same detail approved in many jurisdictions.
Alpine works with the people who own the standard and the people who build it: brand construction and facilities managers, prototype architects and civil engineers, national general contractors and owner's representatives. Each gets what their stage needs, from the prototype detail and guide spec to site layouts, sealed calculations, submittals and kits packed by site and release.
The rollout program guide, sample site submittal package and CMU vs steel cost study are sent after a short form. The guide spec PDF and product data sheet are open downloads.
One standard detail, site-by-site engineering, one price nationwide.
