Equipment pads, access roads and transformer yards near a federal dam come with rules before they come with drawings, and we read the rules first. Alcova sits on the North Platte River upstream of Casper, and its industrial story is water and power. Owners near it, whether utility contractors, irrigation interests or private landowners with a shop to build, need a builder who respects the fence line and the permit trail.
Alcova Dam is a U.S. Bureau of Reclamation structure, finished May 8, 1938, 265 feet high and 763 feet long, and part of the Kendrick Project. The powerplant holds two 18 MW Francis turbines, 36 MW installed, generating about 92,408,000 kWh a year. A facility like that sets a pattern for the neighborhood: controlled access, heavy electrical gear, and work that stops when the owner says stop.
We do not claim any work on the dam itself. We build the support structures around that kind of work: pads, vaults, yards, shops, roads and fenced compounds. Every crew completes a safety orientation, and a permit to work governs any excavation, lift or hot task. Nobody enters a restricted area without escort and sign-in.
Water, power and a very small town
The reservoir holds 184,405 acre-feet in total, with 30,606 acre-feet usable for irrigation. That is a working water system, and the people around it depend on schedules that follow the irrigation season. A construction crew that blocks a road or a canal access in July causes real trouble. We tell owners up front what dates are risky and plan around them.
Alcova had 34 residents in the 2020 census, at 5,371 ft elevation, and contains Wyoming's center of population. There is no local labor pool and very little local supply. Everything comes from Casper or farther away: crew, concrete, fuel, steel and tools. The cost and the schedule reflect that, and we say so at bid time.
Access rules, permits and review paths
Work near federal property may involve additional permission from the managing agency, such as right-of-way, access or encroachment approvals. We do not guess. The owner's counsel and the agency's field office say what applies, and we build the paperwork into the schedule. Local building authority matters too, and Wyoming leaves code adoption and enforcement to local jurisdictions.
For private projects in the area, we follow the same commercial path as in town: engineered plans, a permit application and inspections. Casper's own commercial permit practice calls for a life-safety plan and engineered site and building drawings, and an issued permit runs 180 days. We use that as a baseline and then confirm what the authority with jurisdiction at the site requires.
Support structures near power and water
Typical scope includes equipment pads for transformers, switchgear and pumps; underground conduit and duct banks with pull boxes and vaults; fenced compounds with controlled gates; and access roads that handle line trucks and low-boy trailers. We build in concrete wherever loads or durability call for it.
Pads near water need drainage that keeps the base dry. Frost heave is a constant concern, so we design for depth and drainage, use a granular base and place insulation where the engineer requires it. Duct banks get marked, tested and photographed before backfill so the next contractor knows where they are.
Plan the day around the fence line
A site near a dam or powerplant has boundaries that are not always visible. We start with a survey, a map of the restricted zones and a conversation with the managing party. Then we put the boundaries on the ground with stakes, fence and signs. Machines, trucks and workers stay inside the lines.
Material deliveries are escorted. Sign-in sheets cover everyone on site. The daily plan includes who is where, what the hazards are and when each task starts and stops. Where a utility is live, we lock it out and verify zero energy before anyone enters. These habits come from utility and power work, and they apply to a private site as much as a public one.
What we cover in the river corridor
We work from the river valley upstream of town to the metro and across Natrona County. For projects close to the mountain side of Casper or toward Glenrock, we use the same staging approach: pre-checked materials, short haul distances where possible and a clear plan for weather.
Work in a river corridor also means protecting the water. We use silt fence, wattles and stabilized entrances so mud and fuel stay out of the river. Spill kits ride on every machine. Fuel storage sits in containment, and washouts for concrete trucks are lined and managed. Those practices are not extras here; they are conditions of working near a reservoir.
Safety near water and electrical gear
Hazards stack up near hydro plants: stored energy, high voltage, deep water, steep banks and cold. Our rules are plain. No one works alone near water. Life vests are required near the edge. Electrical work is done by qualified people with lockout and verification. Excavations get shoring or sloping, and gas monitors where needed.
We brief every crew on the site's emergency plan before they begin. Where help is far away, we carry additional first aid supplies and keep a vehicle ready. Weather decisions are made early and with authority: wind, lightning or ice stops work. At the end of each shift the site is left secure, with tools locked, trenches covered or fenced and a written note of what changed.
Common Questions
Do you work on the dam or powerplant?
No. We build support structures around power and water facilities, such as pads, roads, vaults, compounds and shops. Work on the dam itself belongs to the owning agency and its specialized contractors.
What approvals apply near federal property?
It depends on the parcel and the work. Access, right-of-way or encroachment approvals may be needed from the managing agency, and the local building authority handles permits for private structures. We identify which apply before we price.
How do you keep silt and fuel out of the river?
We install silt fence and wattles, stabilize entrances, keep fuel in containment and line concrete washouts. Spill kits are on every machine, and we inspect controls after each storm.
Is labor available locally?
The 2020 census counted 34 residents, so we staff the job from outside and plan transport, supplies and safety coverage as part of the price.
What frost issues should I expect?
Frost heave can lift pads, slabs and fence posts. We use granular base, good drainage and depth set by the design engineer or local authority, and we avoid placing concrete on frozen subgrade.
