Frequently Asked Questions
What does a pipeline contractor do in the Bakken?
A pipeline contractor builds the lines that move gas, oil and water between wells, pads, compressor stations and disposal sites. That covers clearing the right-of-way, trenching, stringing pipe, fusing or welding joints, tie-ins, pressure testing, backfill and reclamation. Eaton Construction does all of it with its own crews, fusion equipment and trucks.
What areas do you serve?
Western North Dakota — Watford City, Williston, Alexander, Arnegard, Keene, Killdeer and the rest of McKenzie, Williams and Dunn counties — from our Watford City shop. Western South Dakota — Belle Fourche, St. Onge, Spearfish, Sturgis, Whitewood and Newell — from our St. Onge office. Ask about projects outside those areas.
Are your crews safety trained?
Yes. All Eaton Construction employees are MSHA trained and OSHA certified. We hold daily tailgate safety meetings and do daily equipment inspections, and both are documented. Hard hats, steel-toe boots and safety glasses are required, and most of our employees have been with us for five years or more.
What do you need from me to put together a bid?
The location (legal description or GPS is ideal), the footage, the pipe material, diameter and pressure rating, any drawings or specs, crossings such as roads or other lines, and your target start date. Send what you have; we will ask for the rest.
Who will actually be on my job site?
Our owner. Wayne Eaton is on the job site every day for quality control, and our crews are cross-trained across fusion, equipment and trucking. All employees are fusion-certified, and new employees don't fuse unsupervised for sixty days, even after certification.
Have a Line to Lay or Ground to Move?
Send us the scope: footage, pipe size and location. An owner will call you back.
