While Milwaukee cannot mandate a specific brand, the city updated its specifications to require adjustable risers with a similar mechanism. That change, has been a quiet success story.

Impressed by the concept, Amin initiated a pilot test on a heavily trafficked street near the city’ s maintenance yard. The goal: observe performance under continuous load.“ We wanted to see how they held up under real conditions,” he says.“ And they did— no failures, no issues.” While Milwaukee cannot mandate a specific brand, the city updated its specifications to require adjustable risers with a similar mechanism. That change, has been a quiet success story.“ At first, some contractors were hesitant,” Amin notes.“ They were used to the convenience of cast iron risers. But that reluctance disappeared quickly— now it’ s the norm.” City crews also install the risers, including models for catch basins, and maintain an inventory of around 100 units for ongoing roadwork. Despite the added engineering, costs remained stable.“ In resurfacing bids, risers are a minor line item,” Amin explains.“ We’ ve seen no significant cost increase, even with the specification change.” With close to 1,000 adjustable risers now in place— and 200 to 300 new installations added each year as part of Milwaukee’ s ongoing repaving program— the results speak for themselves.“ Since we made the switch, we haven’ t had a single riser come loose,” says Amin.“ They’ re reliable, easy to work with, and they’ ve virtually eliminated the risk of damage. That peace of mind is worth every bit of the investment.”
