Palmer, who managed the project, said, “This project was full of obstacles, but we succeeded in completing the last remaining section of the pipeline under the river in March.Underground Utility Construction Services
On top of that, Southern California experienced a wetter-than-average rainy season in 2019, further restricting the already strained construction schedule. The narrow construction window was required by the California Department of Fish and Wildlife to avoid impacts to the least Bell’s vireo and other migrating birds, as well as by a neighboring business that hosts large outdoor events next to the project site throughout the spring and fall.
OurĬonstruction management group oversaw installation of the pipeline.Īfter nearly five years from work stoppage, construction was completed in less than three months. So, DudekĮngineers were brought on to redesign the crossing using HDD techniques. Santa Ana River, which prevented completion of the crossing. Was halted by an unknown obstruction just below the northwestern bank of the Managing a microtunneling installation of a 42-inch steel casing. Pipeline had remained incomplete since 2014, when another consultant was This approximately 1,000-linear-foot portion of 32-inch-diameter The Chino Basin Desalter Authority’s (CDA) Product Water Line under the SantaĪna River, which will provide Western Municipal Water District with completeĪllocation of water to customers from the Chino II Desalter Facility. Installations, and curved pipeline design. Installation lengths, large diameters, multiple simultaneous pipe Successfully designing projects with unique challenges, including large Pipeline Project Saved by HDDĭudek engineers have utilized HDD technology for years, Combined with a more streamlined permitting process, HDD can significantly shorten a project schedule and, potentially, reduce its budget. Horizontal directional drilling construction is faster, as it avoids conflicts like existing utilities that slow down traditional trenching and backfilling construction. In addition, the actual HDD construction process can often be quicker than installation by standard open cut trenching and backfilling. This makes horizontal directional drilling a great option for certain projects, saving time and money and streamlining the permitting process.” “HDD reduces aboveground disruption and can, potentially, completely avoid adverse environmental impacts. “Permitting projects in environmentally sensitive or congested areas takes quite a bit more work,” said Dudek Engineer Kate Palmer. Less community and environmental disruption and.Finally, the new pipeline is pulledīack through the cleared pathway, and installation is complete. Several passes usually occur, depending on Pilot hole is complete, a cutting tool called a back-reamer is attached and The HDD process includes several steps, beginning with boringĪ small pilot hole underground with a continuous string of drill rods. Horizontal Directional Drilling Process and Benefits Offers great potential to reduce a project’s schedule and budget. Minimize surface disruption and often avoid impacts altogether. Horizontal directional drilling (HDD) construction methods can Permitting pipeline projects in extremely congested orĮnvironmentally sensitive areas can be burdensome from a schedule and financial
