Case Studies

Small Volume Provers are benefitting the oil refined products industry. They are small, efficient and more accurate the the old "Ball" provers.  Midwestern Contractors has a deep expertise installing and commissioning these precision measuring devices. Our installations are completed with in-house expertise in civil, concrete, fitting, testing and coating. 

Waste water treatment plants prevent contaminated water from leaving the confines of the facility. These plants extract particulates and contaminants from surface water collected in containment basins. Midwestern Contractors. is proud to play a part in building systems that enhance water quality in industrial facilities. Our quality assurance and safety programs help us keep our employees safe and deliver well made projects to our customers.

This case study describes the process by which a gas processing plant and pipeline came into existence for the purpose of transporting methane from a landfill to an interconnect and custody transfer point and into a natural gas transmission pipeline.

Any hydrostatic test requires planning, attention to detail, execution and experience, to be successful.

A severe thunder storm interrupted this relocation.  After rebuilding the trench, shoring and matted access road, 200 feet of 12" pipe was installed to complete the relocation and eliminate the pipe exposed in the creek bottom. 

When multiple utilities need to traverse rivers, channels, canals or harbors, tunnels are often employed to do the job. This makes it easier to construct and service the utilities. It is also easier to maintain. Over time damage in the form of corrosion can occur. Midwestern Contractors was selected to perform a cut out on a 30 inch, 0.375” WT high pressure, natural gas pipeline. The line was in a tunnel 80’ deep. The entire length of the tunnel was over 400’.

Midwestern Contractor's 12-year story of the commitment and determination required to create a culture of safety. How they developed management strategies, utilized mobile devices and cloud computing, to enable a fresh approach to safety; and the results of those efforts...

Integrity projects are complicated enough when they involve locating anomalies along a buried pipeline that will then need to be excavated, evaluated and repaired. That factor increases significantly when the pipeline involved is connected to a heavily traveled motor bridge over a busy commercial river...

The value of governmental regulation cannot be denied. In addition to numerous safety and environmental benefits it provides a benchmark for maintaining safety and stability during the process of completing field work - be it new infrastructure integration or maintenance and repair.

Pipelines are built to carry products from point A to point B. They are usually underground but sometimes are suspended over creeks and rivers.

Underground storage of natural gas is an important and necessary piece of the energy delivery chain that fuels our homes and businesses. Underground gas storage fields are spread throughout the entire United States.

Thanks to hydraulic fracturing technology natural gas in now abundant in the United States. This abundance has created many opportunities to utilize gas as feed stock in the petrochemical industry, liquify it for export, and connect more communities by extending the distribution system.

Why do pipelines have to be lowered? There are times when catastrophic flooding will remove large amounts of protective soil from the pipeline. Rather than have a normal 5 feet or more to the top of the pipe, there may be only 1 to 2 feet of cover. 

Natural gas is abundant in the United States thanks to innovative drilling techniques and the use of hydraulic fracturing. Once released, this gas, must be transported for use, stored or flared off. Natural gas is made up mostly of methane, four hydrogen atoms attached to one carbon atom. 

Midwestern Contractors was awarded a project in north central Michigan to install a meter and regulation station for natural gas distribution. The project site sloped to the east, was covered with trees and brush and required over 10' of fill. 

When it comes to repairing a pipe drilled in by horizontal drilling methods operators are sometimes left with few options. On a recent Ohio project a right-of-way corridor was very congested with existing pipe that had been drilled in. This 12" pipe, all 0.500' wall, had been in the ground for many years.

The scope was simple, auger under a road and push pipe through, drill 1,400' and pull back pipe, and finally open cut and tie it all together. But Not everyone can wake up, go to work and drill a big hole in the ground that goes in at one point and comes up precisely at another, some 1,400' away.
