DGR Engineering (DGR) collaborated with a long-standing airport engineering partner at the Brookings, SD Regional Airport to provide unique airport-electrical expertise and designed the $2.3 million airport electrical and instrument landing system. The total cost for the reconstruction project was $20 million.

This project involved coordination and design of navigational equipment and systems that are owned and operated by the Federal Aviation Administration (FAA).

Therefore, DGR coordinated heavily with the FAA’s Navaids (navigation aids) Engineering Center in Chicago. The project required significant coordination to comply with the FAA internal equipment procurement process.

The primary runway was also being reconstructed on a new alignment, so this project included new electrical facilities and the relocation of several existing facilities.

High-end aviation-electrical engineering is a DGR specialty. Some firms do airports, some do electrical, not many do both. DGR Engineering is unique, offering both specialties under one roof. This enables DGR to take on more complex airport-electrical projects and integrate these services for clients.

Water Treatment Plant

The building is expandable to add future treatment equipment that can double the treatment capacity as water demands increase in the future. With three times more water available and enough annual water appropriation to operate at full capacity all year long, the new facility has become Red Rock’s primary water source.
