Problem: Founded in 1969, Herzog Contracting Corporation is a giant, with six divisions spread across rail, waste management and roadway construction and maintenance. In 2014, Herzog began implementing a roadway contracting innovation from another firm, the Pivoted Turnbuckle Manhole Riser from American Highway Products. “We’d been using cast-iron risers exclusively to raise manholes to grade,” says Bryan Jones, vice president of project delivery in Herzog’s Heavy Highway Division. “They were effective in many ways, but inventory was a persistent challenge. We perform work for a lot of different municipalities, all with differently sized manholes, and it was difficult to keep every size of riser we may need in inventory.”
Solution: For Jones, the chief advantage of the risers was adjustability. They’re sturdy, flexible rings made of galvanized steel, are easy to set into original utility rims and the pivoted turnbuckle enables fast adjustment to securely fit variously sized manholes. “We first used AHP manhole risers for Wathena, Kansas. I ordered almost 100 risers for that project — we knew from the start they would be a great fit for our operations.”
Result: Since then, Herzog has installed over 1,000 Pivoted Turnbuckle Manhole Risers, keeps a year’s inventory on hand, and has not had any failures to date. Summing up, Jones says, “The AHP risers are a great asset to our operations, and they’ve been incredible to work with over the years.” 888-272-2397; www.ahp1.com
