Manoa Estates Water System Improvements

Hart Crowser completed a geotechnical investigation and design for upgrades to water lines in a portion of Manoa Valley. The project will include replacement and upgrades of 4,000 linear feet of water lines within the roadways and a crossing of Manoa Creek (either suspended on an existing bridge or by horizontal directional drilling). Our scope of work included securing roadway and trenching permits; coordinating traffic control, geotechnical borings and resistivity measurements; and providing design recommendations for trenching and backfill, roadway pavement sections, and corrosion protection.
