In Labette County, Kansas, a concrete bridge structure was in need of replacement. Originally built in the early 1900s, the structural condition of the bridge was very poor, and the neighboring landowner was experiencing damaging flooding events due to back up from the bridge.

The Stark St crossing over Beaver Creek consisted of an undersized concrete box culvert with a broken fish ladder that was prohibiting salmon and other fish species from migrating upstream through the culvert.  

A bridge project in Antioch, CA needed a very special isolation casing that wasn’t typically available.  Engineers reached out to PCP for their help in designing this mammoth casing.

Since 1993, wet conditions have brought water from the upper reaches of this watershed down to the Michigan Spillway Project area.   The Nelson County Water Resource District Board has worked toward emergency pumping to lower this flood for many years.   This project has had many designs made, with protection for downstream impacts and even concerns of invasive species downstream that could migrate upstream.  Hence, a very elaborate pump station is required to control these issues for this project and was permitted. 

Industry uses of corrugated steel structural plate goes virtually unnoticed by the public and engineering community alike as it does not involve transportation facilities. However, structural plate is integral to the operations of quarrying and mining industries, and Pennsy Supply’s Millard Quarry Tunnel in Anneville, PA provides an excellent illustration of the varied uses of this engineering material.

Ultimately, the IDOT selected a proposal by WBK Associates LTD which utilized a 144-inch diameter polymer-coated double wall pipe supplied by Contech Engineered Solutions. The double walled steel pipe with a polymer-coated, 18 gage, smooth interior steel liner and 12 gage, rugged 3x1 corrugated outer steel shell was able to satisfy the AASHTO specification as well as the IDOT section 543.02 requirements.

Pacific Corrugated Pipe Co. (PCP) implemented a variety of actions based on Tier II treatment requirements administered by the Department of Environmental Quality.  PCP installed an Electrocoagulation (EC) Stormwater Treatment System at their manufacturing facility. The Design parameters of the EC system allowed for the discharge of clean water.

After several peak storm events washed out a section of a North Dakota Badlands Forrest Service access road, the Forrest Service teamed up with Kadrmas Lee Jackson’s engineers and Hlebechuk Construction to make some very quick repairs.

How appropriate that it was in February 2015 that Metal Culverts, Inc. supplied  Union Pacific Railroad with 390’ of 60” diameter, 12 gauge (3”X1”) riveted corrugated steel pipe with High Build Epoxy Coating (HBE-95) for their Valentine Project –MP 742.37 located near Sierra Blanca, Texas.

A signaled level crossing had been holding up traffic and impacting safety on a BNSF Railway spur feeding the La Cygne Generating Station, south of Kansas City.  Motorists and railway workers alike all gave it a failing grade.

During the design of their new retention system, Watson Industrial Park presented 2 unique challenges.  The first required a product and logistical solution that would allow for the installation to be completed as it was delivered and the second was a production plan that would allow for everything to be produced AND installed in less than 6 weeks time.

To say water is important to the state of Wisconsin would be an understatement. With over 15,000 lakes in direct proximity to Lakes Michigan and Superior (two of the largest sources of freshwater in the world), and 32,000 miles of streams, Wisconsinites prize their quality water resources. They utilize these resources for drinking water, recreational opportunities, crop irrigation, and as the base of a huge tourism industry.

In 2016, the Atlanta Regional Council revised the Georgia Storm Water Management Manual to incorporate LID (Low Impact Development) water quality methods. SEC designed a 42” perforated, aluminized infiltration system that would return the storm water to the soils.

The project specifications called for construction of a conventional temporary bridge in the median to carry the 3 lanes of traffic for the northbound or southbound bridge as that bridge was being replaced.

Pacific Corrugated Pipe was given the opportunity to value engineer and aid in designing one of the largest rainwater storage retention systems ever installed in the Murrieta, CA area and furnished from their facility.

The Bureau of Land Management was in need of a new, eco-friendly culvert solution that would allow for a proper fish passage west of Wolf Creek in Oregon.  In addition to providing safe passage for fish, this new design called for construction loading and heavy vehicle traffic support on 2 one-way logging roads.

In March of 2016, Crittenden Co., KY decided to replace a structural plate bridge built in approximately 1945.  This bridge is located in the most northern part of the county on Hurricane Church Road, approximately five miles south of the "Cave in Rock" ferry, which still crosses over the Ohio River many times each date.  This bridge has allowed safe passage over a tributary of Caney Fork Creek for many years providing access to the historic Old Hurricane Methodist Church and Cemetery where you can find some of the oldest graves in Crittenden County - some dating back before the Civil War.

Original plans for a new Chrysler Dealership in Pineville, NC included a modular reinforced concrete storm water detention system – but at a hefty price. After a value engineering process, it was decided to go with an aluminized steel pipe combination storm water management system, saving the owner over $300,000!

This bridge allowed passage over Fish Creek. The updated design required a 5 gauge, 22’x 20′ vertical ellipse, galvanized multi-plate for the main channel with a length of 150′.

On either side of the vertical ellipse a round 14′ diameter, 7 gauge, galvanized multi-plate overflow structure completed the design. Each overflow structure was 140’in length.

A 6” minimum benign envelope around the pipe using pea gravel was incorporated to abate the poor resistivity readings that periodically occurred at this site.

This job consisted of 6300 LF of CSP and 3200 LF of spiral rib pipe including several large tees, elbows, & misc. fittings.

With over 14,680 LF (sections varying from 4,594 LF of 15-in diameter to 5,162 LF in 42-in diameter and 263 LF in 60-in), the mobile mill offered the perfect flexibility for the variety of pipe diameters needed to complete the job.

These pipes are set vertically into a concrete base and sealed with silicone or a spray sealant. They are then covered with a solid vented lid and plumbed for use.

Corrugated steel water tanks are designed to be an aesthetically pleasing and cost effective solution used for  rain water harvesting.

The deteriorating culvert had experienced major encroachment along the toe of the slope after a major rain event and catastrophic washouts.

The North Dakota Department of Transportation had a problem with joint separation and spalling concrete in a 10’ x 8’ cast-in-place Reinforced concrete box culvert built in 1934, and extended in 1960.

Constructed in 2011, this is the longest single span box culvert of any material in North America. This was also the first large span steel buried bridge to take advantage of its flexible nature in the foundation design.

This half-round CSP structure, with its own footing plates, was designed by Pacific Corrugated Pipe Co. for bridging small streams on a temporary basis. The installation was along the Smith River access road near Elkton, RO and completed under the auspices of Oregon Department of Fish and Wildlife to ensure compliance with environmental regulations.
