The only way to do the job is to do the job right.

The Spire STL Pipeline will be constructed in segments, also called spreads. The process flows very much like an assembly line.

Pipeline construction is labor intensive and requires many skilled workers following a detailed process. Excellent communication between all the moving parts of the assembly line is vital to the success of the pipeline project.

Communication between the construction crew, land agent and the property owner is very important. We will work diligently to keep you informed of the process and to answer all your questions.

It’s not just how we dig, but how it affects the community.

During construction we will make every effort to minimize your inconvenience. Working with Federal Energy Regulatory Commission (FERC) and other regulatory agencies, we will develop plans to minimize noise, dust and traffic issues. We will work with local communities to create safety and traffic plans to insure that safety remains the number one priority.

Construction doesn’t end until the landscape is restored.

Weather permitting, restoration efforts begin as soon as possible after construction work is complete to restore the land. We use a two-phased approach. First is “preliminary grading” to backfill the trench. Next is a "final grading" process to smooth out and clean up the area, planting grass seed and other native vegetation, and restoring any necessary drain systems. Restoration measures are monitored and maintained until the area is similar in nature to its original condition.

Pipeline construction sequence: Land surveying, clearing, grading, trenching, pipeline stringing, bending pipe, welding, x-ray and repairs where necessary, coating where necessary, lowering the pipe, installing valves and fittings, back-fill, testing, clean-up and restoration.
