Pilot Tube Micro-Tunneling – Seattle, WA
City of Seattle – South Lake Union
Trenchless Construction Services, working as a sub-contractor, installed 320 LF of 8” gravity sewer at a 1% grade utilizing our BOHRTEC BM400LS Pilot Tube Micro-Tunneling machine. This project presented many challenges due to the dense amount of businesses in the area and other large construction projects sharing the same alleyway. Although these challenges limited the working hours and footprint of the work area the project was completed with almost no impact to the surrounding businesses and construction projects.
