Complete civil packages for utility solar across Indiana: clearing, mass grading, access roads, collection trenching, SWPPP, fencing, and substation civil.
Backwell is a civil site work general contractor serving utility solar EPCs building in Indiana. We contract complete civil packages: clearing, mass grading, access roads, trenching and underground utilities, erosion control and SWPPP, fencing, and substation civil, all under one contract with Backwell field leadership on site.
Indiana is one of the most active utility-scale solar states in the Midwest, driven by coal retirements at NIPSCO, AES Indiana, and CenterPoint Energy Indiana, plus independent developers selling into MISO. The largest single build is Mammoth Solar in Starke and Pulaski counties, where Doral Renewables has phases under construction with commercial operation targeted for late 2026 and 2027. Utility-owned projects have clustered in the northwest counties of Jasper, White, Starke, and Pulaski, and in the southwest coal belt counties of Pike, Posey, Knox, and Dubois where retiring generation leaves usable interconnection rights. Sites are typically flat former row-crop ground with heavy agricultural drain tile, which makes tile location and repair, access road construction, erosion control, and stormwater compliance the controlling civil scopes. Solar-plus-storage is now standard on utility-owned projects in Indiana, which adds battery pad, foundation, and containment sitework to the civil package.
Solar EPCs and developers usually search by the county or the nearest town to the site. These are the Indiana markets we cover:
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. Indiana does not issue a statewide general contractor or commercial building contractor license. Contractor licensing and registration is handled at the city and county level, so requirements vary by jurisdiction. Larger cities including Indianapolis, Evansville, Fort Wayne, and South Bend run their own contractor licensing or registration programs, generally requiring a fee, a contractor bond, general liability coverage, and workers compensation, with some jurisdictions also requiring an exam. Many rural solar host counties have no general contractor license at all, but a civil contractor should still expect county road use and haul route agreements, road maintenance bonds, county drainage board coordination on regulated drains and tile, and local building or improvement location permits. Verify the specific city or county requirement before mobilizing rather than assuming a state credential exists.
Construction stormwater. Construction Stormwater General Permit, known as the CSGP, issued by the Indiana Department of Environmental Management, IDEM. It applies to construction activity disturbing one acre or more of total land area, and to smaller areas that are part of a larger common plan of development or sale. As of December 18, 2021 the CSGP replaced the prior program administered under 327 IAC 15-5, commonly called Rule 5. Coverage is obtained by filing a Notice of Intent, or NOI, with IDEM, supported by a stormwater pollution prevention plan. Local soil and water conservation districts and county or municipal MS4 programs typically review and inspect on IDEM's behalf, so a utility-scale solar site will usually deal with both IDEM and the county SWCD. Backwell carries the SWPPP scope, installs and maintains the controls, keeps the inspection log, and closes the permit out with final stabilization.
Prevailing wage. Indiana has no state prevailing wage law. The Indiana Common Construction Wage Act was repealed effective July 1, 2015, and the state has not replaced it, so there is no state level wage determination for public or private work. Federal Davis-Bacon prevailing wage still applies to federally funded work, and applies to utility-scale solar through the Inflation Reduction Act labor requirements: projects of 1 MW AC and larger must pay Davis-Bacon prevailing wages and meet registered apprenticeship ratios to claim the full value of the investment or production tax credit. In practice that means nearly every utility-scale solar project in Indiana is built on certified payroll with apprenticeship participation even though the state itself imposes nothing. Owners and EPCs will also often impose their own project labor agreements or workforce commitments on top of the federal requirement. 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.
Send plans, a scope of work, and the schedule through the form below or call (315) 400-2654. We review the civil package, walk the site if it is at that stage, and return a scoped proposal with a schedule of values, stated fill allowances, and unit rates for overages. A one-page capability statement is available for prequalification files.
Plans, scope, and schedule reviewed and answered promptly.
