Industrial Site Work at the Pueblo Chemical Depot
Ground that once held a chemical stockpile deserves a careful look before anyone pours a footing on it, and that is where we start when an owner brings us a parcel at the Pueblo Chemical Depot. We build and prepare sites east of Pueblo for industrial, storage and rail-related users, working from the records, the soil and the owner's requirements, and we say plainly what we do not yet know.
The Army opened the depot in 1942 on 24,202 acres, 14 miles east of Pueblo, and the 1988 base realignment commission kept it open because of its chemical stockpile. It held 2,613 tons of mustard agent in about 780,000 munitions. Destruction of all munitions was completed on June 22, 2023, and the Army decommissioned the depot on September 12, 2024.
For a builder, those dates mean the site is now moving from federal use toward civilian redevelopment. The land has roads, magazines, utilities and a pilot plant campus, and each piece needs its own review. We treat the depot as a site with history, not a vacant lot.
Doing the homework before the dig
Our process on former military ground starts with records. We ask the owner for environmental reports, clearance documentation and any restrictions on digging, then walk the parcel with those documents in hand. If the paperwork has gaps, we say so and recommend further investigation before design money is spent.
On site, we brief crews on what to do if they find something unexpected, whether that is buried debris, stained soil or an unfamiliar structure. Work stops, the area is marked and the owner is called. We do not guess about ground conditions on a site like this.
Documentation is the other half of safety. We keep daily logs, photos of excavations before backfill and a record of every utility crossing, and we hand them over at closeout. If the parcel changes hands later, the next owner gets a clear picture of what was built and what lies below it.
A pilot plant, a workforce and a handoff
The Pueblo Chemical Agent-Destruction Pilot Plant began construction in 2012 and operations in September 2016, had about 1,500 employees in 2023 and has spent more than $500 million with Colorado companies. It shows what a large technical project does for the regional contractor base, and it also shows that skilled crews have worked on this ground before.
A US 50 interchange serves the depot at about mile 329.1, east of the Pueblo Memorial Airport interchange. That highway tie makes the site workable for freight users. We have a related page on the nearby PuebloPlex redevelopment, which is taking on land that left Army use.
What a buyer should expect
Parcels on the depot may carry restrictions, easements and conditions that a normal industrial lot does not. The soil may have been disturbed, and utilities may be old or oversized for the new use. Fire flow and power may be excellent in one area and absent in the next. Freight users in logistics and distribution care most about the road and rail access, and we check that against the utilities.
We recommend a staged investigation: records review, surface walk, geotechnical borings and, where needed, environmental sampling by qualified consultants. The cost of that work is small next to a redesign. We coordinate the schedule so investigation and design overlap, and we hold the construction budget open until the results arrive.
Distance is part of the picture. The depot is 14 miles from Pueblo, so concrete, aggregate and crews all travel. Ready-mix has a limited haul time, which means large pours need a plan for plant capacity, truck cycles and temperature. We discuss that during preconstruction so the owner does not discover it on pour day.
Phased construction on large, quiet ground
A site this large invites phasing, much like the phased construction we do on occupied sites. We put roads, drainage and utilities in first for the area an owner plans to use, then build the first building while keeping the rest of the parcel untouched. That approach limits disturbance and gives the owner time to decide on later phases.
We also keep our footprint small. Laydown areas, haul roads and equipment parking are mapped before we mobilize, and we restore them when the work is done. Careful housekeeping makes inspection and handover easier.
Permits and approvals on federal-to-civilian land
Who reviews a building on this land depends on who owns the parcel and who has jurisdiction. The Pueblo County building division lists the 2021 International Code Council codes and the 2023 National Electrical Code as enforced and links its Title 15 amendments. Beyond building permits, a transfer parcel may carry deed terms, access controls and environmental covenants.
We ask the owner for the governing documents at the start and read them against the project. If something conflicts with the use or the schedule, we raise it before design, not after. Our list of approvals is part of the proposal.
Energy and fire codes apply as well. Colorado requires any county or municipality that updates a building code on or after July 1, 2023 to adopt an energy code at least as strong as the 2021 IECC, and from July 1, 2026 the benchmark is the state model low energy and carbon code, so we confirm which edition the reviewing jurisdiction has adopted before sizing insulation, lighting and mechanical systems.
Services that suit this ground
Common needs include site clearing and mass grading, industrial demolition services for obsolete structures, rail spur site improvements and stormwater work. Owners in utilities and power also look at the open land for yards and equipment buildings.
When demolition is involved, we follow a plan that includes surveys for hazardous materials, licensed abatement and disposal records. A building that has stood for decades can hide lead paint, asbestos or fuel tanks, and the plan accounts for them.
Evaluating a parcel at the depot?
Send us the parcel and any records you have. We will review them, walk the ground and give you a plain list of risks, approvals and costs. Nearby, the Transportation Technology Center is another large tract worth comparing.
Questions and Answers
Is the depot ground safe to build on now?
Destruction of the stockpile was completed on June 22, 2023, and the Army decommissioned the depot on September 12, 2024. Whether a specific parcel is ready for construction depends on its own records and conditions. We review the documents, walk the ground and recommend investigation before any design money is spent.
How far is the depot from Pueblo and the highway?
It is about 14 miles east of Pueblo, with a US 50 interchange at about mile 329.1, east of the airport interchange. Trucks can reach I-25 and the city by that route. We plan material hauls and crew travel with the distance in mind.
What happens if we find something unexpected in the ground?
We stop work in the area, mark it, document it and call the owner. A qualified consultant evaluates the find, and we resume only when the owner approves the plan. The proposal states how that process will work and who pays for what.
Can a tenant reuse the old magazines or plant buildings?
Possibly. We inspect the structure, floor and utilities, then report on what upgrades the new use would require. Some buildings suit storage with minimal change, while process uses may need more work or a new building.
Who is the right contact for access and approvals?
That depends on the parcel. We help you identify the owner of the land, the permit authority and any other approval bodies, then keep a single approval tracker for the project. You get one list of what is required and who must sign.
