Upgrades to natural gas pipeline and meters are completed annually by a major utility provider in communities throughout Michigan to ensure safe, reliable, and more environmentally friendly natural gas delivery. In 2024, the utility’s System Improvements program focused on a 20-mile segment between Mesick and Buckley that included a complex crossing of the Manistee River, Wheeler Creek, and an aquifer. Wade Trim provided survey, design, horizontal directional drill (HDD) modeling, permitting, and construction package support for the subaqueous crossing.

Drastic elevation changes, unique project limits, and constraints from bridge foundations added complexity to the project. Geotechnical subconsultants on our team obtained soil data to ensure feasibility, and BoreAid modeling software was used to identify any potential issues prior to construction. To withstand the water depth and conditions, the design features 6-inch steel pipeline with a compounded epoxy coating to protect the pipe during HDD installation. Pipeline depths, clearances from exiting utilities and rights-of-way, and specifications were selected to meet permitting requirements and utility standards.
