What The Diamond Engineering Company does
The Diamond Engineering Company is an employee-owned, privately-held heavy civil construction contractor headquartered in Grand Island, Nebraska, with a regional branch in Wichita, Kansas. Founded in 1920, the company has operated continuously for over 100 years and serves municipal, industrial, commercial, and residential clients across five Midwestern states: Nebraska, Kansas, Colorado, Oklahoma, and Missouri. The firm offers four integrated service lines: Underground Utilities (water mains, sanitary and storm sewers, lift stations, lagoons, HDPE pipe installation and fusion); Telecommunications (FTTX, directional drilling in rock, frost, and river conditions, cable plowing, manhole and conduit installation); Paving and Concrete Work (parking lots, streets, roads, and highway paving via slip form pavers, plus asphalt and concrete repair); and Bridge and Structure Work (bridge construction and repair, box culverts, pile and sheet driving, demolition).
The business operates project-based, custom-quoted work sourced through competitive bidding on public tenders, direct enterprise engagement (quote request, phone, email), and long-standing relationships with municipal governments and named clients including AT&T (Kansas telecommunications footprint) and O'Conner Enterprises (real estate development). Pricing is per-project and not publicly disclosed. The company owns and operates a substantial fleet of specialized heavy equipment, including two 80-ton Hitachi cranes, a large demolition excavator, slip form pavers capable of one-pass placement up to 37 feet wide, directional drills, and cable plows. It advertises 24/7/365 emergency response, environmental compliance (TECP and erosion control), and in-house permit processing support.
Corporate governance is run by employee/shareholders who sit on the Board of Directors. Leadership includes President/Board Member Matt Ley, Secretary/Treasurer and Finance & Administration Manager Doug Sass (25+ year tenure, former IRS auditor), VP/Project Manager Tom Furse, VP/Board Member Ben Thayer (former City of Grand Island engineering superintendent), and HR Director/EEO Officer/Safety Manager Ryan Krolikowski.
