Two very different jobs in one county. The Mesilla Valley floor is Rio Grande alluvium mapped as Gila, Glendale, Harkey, Anthony, and Brazito soils, deep and stone free, with shallow groundwater and a dense Elephant Butte Irrigation District canal and drain grid. Above the valley the ground steps up onto the La Mesa surface and the bajadas off the Organ, Doña Ana, and Robledo mountains, where Berino, Doña Ana, Onite, Bluepoint, Simona, and Hueco soils sit over caliche. The Doña Ana and Simona series are defined by strongly cemented calcic and petrocalcic horizons, and that caliche is the single biggest civil variable out there. Sand sheets and mesquite coppice dunes cover much of the west mesa. Drainage is flashy ephemeral arroyo flow off the mountain fronts plus the regulated river corridor.
On the mesa, clearing means grubbing mesquite coppice dunes, and once the binding shrub is gone the sand sheet moves, so stabilize behind the dozer or you chase sand all season. Mass grading hits cemented caliche at shallow depth in the Doña Ana and Simona units, so budget hoe ram or hydraulic breaker on cuts and expect it to skew your cut to fill balance. That same caliche processes into excellent road base. Collection trenching is the classic caliche problem: slow cutting, oversize spoil, and imported sand bedding for conduit. Down in the valley the calculus flips to soft alluvium, a shallow water table, dewatering on deeper runs, and permitted crossings of EBID canals and drains. Erosion control on the mesa is about arroyo conveyance and cross drainage sized for flash events, not perimeter silt fence.

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.
