About this file
This is a test hole report sheet prepared by VacX Utility Coordination Services documenting subsurface utility investigations conducted for the City of Beaverton on July 17-18, 2025, along SW Hart Road and at the intersection of SW Hart Road and SW Sorrento Road. The document contains seven detailed test hole reports (TH #ZP-1 through TH #ZP-7) identifying the locations, depths, and specifications of underground utilities including Ziply Fiber communications concrete encasements, NW Natural gas lines, and City of Beaverton water infrastructure. The investigations document pavement core thicknesses ranging from 6 to 9 inches of asphalt concrete, utility cover depths, and horizontal/vertical distance measurements from established reference points. All pothole investigations were completed in mid-July 2025 in support of CIP 4211, the SW Hart Road Traffic Circle Public Waterline Improvements project, which involves installation of approximately 1,800 linear feet of zinc-coated ductile iron potable water pipe in sizes ranging from 4 to 12 inches. No utility tell-tales were set during any of the test holes, and all measurements were documented with elevation data referenced to storm crossing points. The work was prepared by Jason Jones from VacX, with contact information provided for utility coordination services.
The test hole data provides essential subsurface information necessary for the safe execution of waterline installation work along SW Hart Road. These utility locates identify existing communications infrastructure, gas lines, and water utilities that contractors must avoid or coordinate around during construction activities. The pothole investigations document specific depths and locations where utilities cross the project alignment, with particular complexity noted at test hole ZP-5, located at the intersection of SW Hart Road and SW Sorrento Road, where multiple utilities (communications, gas, and water) converge. The documentation indicates that some pothole locations were relocated in the field based on the locates conducted, reflecting adjustments made during the planning phase. This utility coordination information is critical for contractors bidding on or executing the CIP 4211 waterline improvements project, as it informs traffic control planning, excavation sequencing, and coordination requirements with existing utility operators.
