Complete civil packages for utility solar near Columbus, NM: clearing, mass grading, access roads, collection trenching, SWPPP, fencing, and substation civil.
Backwell contracts complete civil site work packages for utility solar EPCs building near Columbus in Luna County, New Mexico. One contract covers clearing through final stabilization, with Backwell field leadership on site.
Thirty two miles south of Deming at the end of NM 11, at the port of entry across from Palomas. Everything in and out of a project down here trucks up NM 11 to I-10, so haul cycle time, not terrain, is the cost driver.

Luna County is the Mimbres Basin, a closed basin with no outlet to the sea. The Mimbres River comes down out of Grant County and simply dissipates near Deming, and the basin drains internally toward playas east and south of town. The county floor is broad alluvial fan and bajada building off the Florida, Cedar, and Tres Hermanas mountains, grading into fine basin floor sediment. The Mimbres series has its type location in the Deming area and dominates the low terraces, floodplains, and lower fan positions: very deep, well drained, medium to moderately fine textured silty sediment. NRCS mapping there works in Mimbres and Mimbres-Verhalen associations, with Verhalen bringing heavy shrink-swell clay into the picture on the flatter basin positions. Caliche is common in the fan soils, and the playa flats are alkaline and salt affected.
Clearing is creosote and mesquite over most of it and is fast work. The real decision is where the Verhalen clay shows up, because that is expansive material that loses strength wet, and pile driving, trenching, and haul roads all behave differently on it than on the silty Mimbres soils that make up most of the bajada. On the fans expect caliche stringers in cuts and plan to process rather than import base. Grading is generally easy because slopes are long and gentle, so the earthwork question is usually fine grade tolerance and drainage rather than volume. Collection trenching in the silty basin fill is fast but the walls are unstable dry, so plan on shoring on anything deep. Because the basin is closed, there is no downstream receiving water to discharge into: erosion and sediment control means on site retention and infiltration, and any grading that blocks natural sheet flow across a fan will pond water somewhere it did not before.
Full detail on the Luna County market is on the Luna County solar civil page.
We price the package as one scope under one contract, so the EPC has a single point of responsibility for the civil critical path instead of managing separate clearing, earthwork, and utility subcontracts.
Backwell superintendents, project managers, and lead operators run every site. We mobilize company equipment for the core scope and scale each project with leased production fleets, qualified regional subcontractors, and agency-placed field staff, all under Backwell supervision and a single contract.
Contractor licensing. Yes. New Mexico requires a contractor license issued by the Regulation and Licensing Department, Construction Industries Division (CID), for work meeting the statutory definition of a contractor. Commercial civil sitework is generally carried out under the GB-98 general building classification for commercial and residential building work, or under the GA series for heavy and highway type work, where GA-98 covers asphalt, bitumen and concrete construction and carries the authority of the GA-1 through GA-5 classifications. A qualifying party must sit for the applicable trade and business and law exams, and a contractor bond, currently 10,000 dollars, is required before CID will issue the license. An out of state contractor should confirm the exact classification match for its scope, earthwork, grading, trenching, roads and foundations, directly with CID before bidding, since the classification map is scope specific.
Construction stormwater. New Mexico is not an authorized NPDES state. The U.S. Environmental Protection Agency, Region 6 in Dallas, is the NPDES permitting authority for all facilities in New Mexico, so construction sites disturbing one acre or more are covered under the federal EPA Construction General Permit (CGP), with a SWPPP prepared and a Notice of Intent filed through EPA's electronic NOI (eNOI) system. The New Mexico Environment Department Surface Water Quality Bureau, Point Source Regulation Section, performs compliance inspections on behalf of EPA and handles Clean Water Act Section 401 certification, and reports go back to EPA Region 6. New Mexico legislation has given NMED statutory authority to move toward a state administered NPDES equivalent program, so contractors should confirm at bid time whether the federal CGP or a newly effective state permit governs the specific site. Backwell carries the SWPPP scope, installs and maintains the controls, keeps the inspection log, and closes the permit out with final stabilization.
Prevailing wage. Federal Davis-Bacon prevailing wage and apprenticeship requirements apply through the Inflation Reduction Act to projects above 1 MW that claim the increased ITC or PTC rate, which covers essentially every utility-scale solar project in this list, so certified payroll and registered apprentice ratios should be assumed on the civil scope. On top of that, New Mexico has its own state prevailing wage law, the Public Works Minimum Wage Act, administered by the New Mexico Department of Workforce Solutions, Labor Relations Division, which sets wage decisions for public works contracts above the statutory threshold. Privately owned utility-scale solar is generally not a public work under that Act, but it can be pulled in where a public entity, state or local funding, or a public land or municipal utility element is part of the deal, for example projects contracted to a county or municipal offtaker. Confirm with the owner at bid time which wage determination governs, and expect certified payroll reporting either way. For projects claiming the full ITC or PTC, Backwell produces Davis-Bacon certified payroll, pays the applicable wage determination, and supports apprenticeship labor-hour compliance.
