HDD infrastructure project named nation's best
Michels is honored to be part of the project being presented the 2020 Construction Risk Partners Build America Award for Best New Utility Infrastructure by the Associated General Contractors of America. The award program honors some of the toughest, most innovative and successful projects completed in 2019.
Michels used horizontal directional drilling to replace 3,500 linear feet of deteriorated 24-inch cast iron waterline with new 24-inch fusible PVC pipe installed 40 feet beneath the channel bottom of the southern portion of Pearl Harbor in Aeia, HI. Because the PVC pipe was not expected to withstand impacts caused by existing unfavorable soil conditions, Michels first installed a 30-inch diameter steel protective casing along the entire length of the crossing to house the plastic pipe.
Special precautions were implemented to not disturb an asphalt runway parallel to the pipe laydown area as ordinance sustained from heavy gunfire by Japanese Zero long-range fighter aircraft during the surprise attack on Pearl Harbor is imbedded in the runway and is being preserved.
“Improving America’s infrastructure takes vision and grit,” said Tim McGuire, Vice President, Michels. “We are proud of the reputation we’ve earned for succeeding at projects that test our capabilities and expand the potential of our industry.”
Healy Tibbitts Builders was the general contractor on the Pearl Harbor New Underwater Waterline Crossing project, which also included the installation of 834 feet of 24-inch and 1,661 feet of 12-inch ductile iron pipelines to make connections to existing waterlines on both sides of the channel.
The crossing was the final link in the U.S. Navy’s Joint Base Pearl Harbor-Hickam regional water distribution pipeline system, delivering updated water service to all base facilities.
