Utility and Power Infrastructure Construction in Pueblo, Colorado

A 240 megawatt solar field is part of the long-rail mill project on Pueblo's south side, and a 230 mile pipeline from Pueblo Reservoir to Lamar and Eads, serving communities in the Arkansas Valley, broke ground in 2020. Those two projects frame what utility and power owners need here: a lot of dirt moved, a lot of trench opened, and a lot of concrete placed in places where nobody has a building. The work is spread out, public in places and private in others, and it depends on access roads, laydown space and crews who understand how underground utilities fail.

We build for utility owners, independent power producers and large industrial customers who need their own power or water infrastructure. That means substation pads and grounding grids, duct banks, equipment foundations, access roads, fencing and stormwater control. It also means working around existing facilities: the steel mill, the rail test center and the dam are all operating assets that cannot stop for a contractor.

We keep the scope civil and structural, and we work with the electrical and mechanical contractors the owner selects.

Earthwork, trench and concrete under one plan

Utility work is mostly earth and concrete. We coordinate site clearing and mass grading for substations and solar fields, trench and backfill for conduit and pipe, and forming and placing the concrete for pads, vaults and duct bank encasement. We survey as we go, because underground utilities are expensive to correct when they are off by a foot.

Large solar and equipment sites need stabilized laydown yards for delivery of modules, racking, transformers and breakers. We build them with the right base for heavy deliveries and the drainage to keep them usable after rain. A flooded laydown yard delays everything, and the cost of fixing it is higher than the cost of building it right.

Weather windows, outages and procurement

Utility schedules are controlled by outages and long-lead equipment. A transformer can take longer to arrive than the rest of the project takes to build, so we order the foundations and the grounding grid to match, not the other way around. If the owner has an outage window for tie-in, everything else is planned backward from it, and we hold the crews and the crane for that date.

Weather matters in a different way than it does for a building. Trenches and open grading are vulnerable to storms, and large sites need erosion control in place before the first cut. The site utilities package we build for plants follows a similar sequence, and the lessons carry across.

Excavations, cranes and energized equipment

Excavation is the biggest hazard on utility work, with energized equipment second. We shore trenches, keep spoil back from the edge, and maintain ladders and ramps for exits. Cranes working near energized lines need a clearance plan with spotters, and no work goes forward until the utility confirms the status of the line.

Heavy industry has its own risks. When we work inside the steel mill area, we follow the plant's permits, hot-work rules and traffic plans. Our metals and heavy industry work covers those rules, and our approach to data center power shows how we coordinate with electrical contractors.

Questions and Answers

Do you build solar fields?

We build the civil side: grading, access roads, stormwater, laydown yards, equipment pads and fencing. Racking, modules and electrical installation are usually by specialty contractors selected by the owner or EPC. We coordinate our work so the site is ready when they arrive and drainage works after rain.

Can you work near a dam or reservoir?

Yes, with the owner's and agency's requirements. Work near Pueblo Dam and Lake Pueblo involves environmental controls, public access and agency approvals. We plan the access route, erosion control and schedule around those constraints and bring the permits into the plan at the start.

How do you protect existing utilities?

We locate and pothole before we trench, mark lines on the ground, and keep a procedure for what happens when something unexpected turns up. We keep a clear record of what we found. That record helps the owner and the next contractor.

What is a realistic timeline for a substation pad and duct bank?

Depends on size and outage windows, but the civil work is usually a matter of weeks to a few months once permits and survey are done. Procurement and the owner's electrical work take longer. We schedule our work to be complete when the equipment arrives, not earlier or later.

Do you work with public utility bidding?

Yes. We read bid documents carefully, ask questions in the question period, and price the work as drawn. If you are a public owner, tell us about your procurement process early, so we understand how to participate.
