Northern Natural Gas Relocation

Southwestern WI | Energy

Overview

Overcoming numerous environmental and topographical roadblocks, ISG relocated a natural gas pipeline four miles to enable a major construction project.


Opportunity

A major construction project necessitated the relocation of a natural gas pipeline, posing unique design challenges due to the topography of the area.

Solution

In order for a major construction project to begin in southwestern Wisconsin, a gas pipeline intersecting the site required a four-mile relocation. This project utilized ISG services for erosion control, surveying, and staking in a challenging topography, with two railroad crossings and arduous road alignments. Coordination with the Department of Natural Resources was necessary to gain compliance for state and national permitting for threatened and endangered species, as well as historical and archaeological surveys. This included developing a construction schedule that considered habitats and natural resources at the site. From obtaining permits through project closeout to the final inspection, ISG was able to meet the expedited timeline for the client so they could to move forward with construction.
