For Dennis Tripp, the most memorable project in his career was the Newton, Iowa sewer improvement project. Tripp started working on the project in the late 1970s when he spent several months in Newton with a subcontractor's crew as he coordinated and observed the SSES (Sewer System Evaluation Survey) field work, including manhole inspections, lamping the sewer lines, flow monitoring, and smoke testing. During the design phase in the early 1980s, Tripp was heavily involved in the design of all of the collection system improvements, including gravity sewers to 36 inches in diameter and force mains to 18 inches in diameter. The total length exceeded 60,000 feet.
During construction, Tripp was one of the observers for the pipelines portion of the project. On this portion of the project, Stanley Consultants wrote a very small number of ITCs (Instruction to Contractor) and only one of them involved a change in the contract fee. That one was a $50,000 deduct.
Another ITC was more memorable. It was required when the contractor did not believe the plans were correct when Stanley Consultants called for a 22.5-degree elbow (vertical bend) in the bottom of a ravine he was crossing with an 18" DI force main. The contractor insisted he needed a 45-degree elbow and proceeded to install it. Two lengths of pipe later, he was coming out of the ground. "We approved his removal of one length of pipe and the installation of a 22.5-degree bend with tie-rods on both ends to correct the pipe alignment," says Tripp.
For its work on the improvement of the water treatment plant, Stanley Consultants was recognized with a letter of commendation from the Iowa Department of Natural Resources.
