Production Drilling for Arrays, Inverters, and LBD Foundations

At ARI, production drilling is the core of how we support utility‑scale solar projects—across arrays, inverter pads, LBD foundations, and critical equipment locations. Our crews and tooling are configured to handle difficult ground conditions while maintaining predictable rates, clean holes, and tight tolerances, so your foundations install smoothly and stay on schedule.

ARI’s commitment to excellence, technical expertise, and adherence to the highest industry standards has consistently enabled us to deliver extraordinary results on complex sites. Our production drilling programs create strong, repeatable foundations for racking, inverters, transformers, and BESS or LBD equipment, helping EPCs and owners avoid re‑drives, redesigns, and costly delays.

Focused on the Foundations That Drive Performance

We plan and execute drilling around the structures that matter most to overall project performance:

• Array pile foundations across priority blocks and high‑risk geotechnical zones.

• Inverter and transformer foundations with higher load, vibration, and settlement sensitivities.

• LBD, collection, and equipment pad foundations that sit at the heart of site electrical infrastructure.

By aligning drilling scope with these critical elements, we help stabilize structures, reduce long‑term movement risk, and support reliable electrical performance over the life of the asset.

Advantages of Partnering With an Indian Economic Enterprise (IEE)

Additionally, as an established Indian Economic Enterprise (IEE), ARI offers strategic benefits beyond field performance. Under the Buy Indian Act and related programs, federal agencies and certain prime contractors can give preference or set‑aside opportunities to qualified IEEs, expanding project access and creating competitive advantages on eligible work.

Collaborating with ARI can also unlock potential financial benefits for primes through programs such as the Indian Incentive Program, which provides a rebate on subcontract amounts awarded to Native‑owned enterprises in qualifying defense contracts. Partnering with ARI demonstrates a tangible commitment to tribal economic development while potentially improving project economics and competitiveness in federal and utility‑adjacent markets.

Commitment to Tribal Economic Growth and Renewable Energy

Our IEE status reflects a broader commitment: using our technical capabilities in solar and storage foundations to drive economic growth within tribal communities. By choosing ARI, project partners gain a specialized drilling contractor and a pathway to support Indigenous economic resilience through meaningful, revenue‑generating work.

As we continue to advance production drilling methods for arrays, inverters, LBD, and storage foundations, ARI stands ready to bring this combination of expertise and economic impact to future solar ventures—helping build stronger projects and a cleaner energy future at the same time.
