Trenchless relocations of existing utilities for the Central Artery/Third Harbor Tunnel Project
- Parsons Brinckerhoff, Boston, MA (United States)
Utility construction in Greater Boston historically has been accomplished with traditional open cut methods where workers excavated trenches of various widths and depths to install pipes, conduits, duct banks, etc. The use of trenchless techniques had been limited to large diameter pipes. Lately, there has been a noticeable shift toward the use of trenchless installation methods because of recent advances in the capabilities of tunnel boring machines, jacking systems and microtunneling equipment. With the on-going construction of the $ 7.9 billion Central Artery/Third Harbor Tunnel Project (CA/T) in Boston, it is apparent that utility construction is going through a dramatic transition to more routine acceptance and use of trenchless techniques to install utilities. This paper will present several of the technical issues and challenges faced by the Massachusetts Highway Department (MHD) and its Management Consultant Bechtel/Parsons Brinckerhoff (B/PB) for utility system replacements and improvements during the design and construction of the (CA/T) Project.
