2017 Hall of Fame: 14th Street Improvements
Contech Engineered Solutions are the recipients of the 2017 Hall of Fame award for their work in Ocala, Florida on phase two of the 14th Street improvements.
The Hall of Fame project of the year award is given to projects which demonstrate not only the versatility of corrugated steel solutions, but also the resilience of these products.
In 1986, the City of Ocala, Florida, began the second phase of roadway improvements scheduled along NE 14th Street to widen the two-lane roadway. To accommodate the increased vehicular traffic along this urban section, the City wanted to add turn lanes, signalization and improve drainage.
Specific drainage improvements included the installation of a storm sewer system along the widened corridor. Originally specified with reinforced concrete pipe (RCP), the City decided to use spiral rib corrugated steel pipe manufactured by Contech Engineered Solutions LLC.
By designing the storm sewer system with 1 mile of 18” through 72” diameter aluminized type 2 (ALT2) spiral rib corrugated steel pipe, the city was able to yield a cost savings of over $50,000. CSP is ideal for storm sewer applications due to its light weight (weighing less than 10% or reinforced concrete pipe), long lengths, low installation cost, and hydraulic capability. This storm system was designed with the added durability of ALT2, easily providing a minimum expected service life of 75-years.
The installation was performed well within the one year contract awarded to the bidding contractor, Hamlet Construction. The owner of Hamlet, Harvey Vandeven, stated, “It saved money, it saved time, and it saved production.”
As part of a durability assessment for ALT2 corrugated steel pipe, this storm sewer system was inspected in 2016. The aluminized coating is a two-layer, metallurgically bonded composite, which enable the superior design life expectancy.
The core sample yielded exceptional results providing evidence that the pipe is in great condition and performing as expected. These findings have been reinforced by the 2014 NCSPA Report entitled, “Durability of Aluminized Type 2 Coated Corrugated Steel Pipe Exposed Throughout the United States.”
