HS2 Old Oak Common

Project overview

Joseph Gallagher Ltd acted as a subcontractor on the Old Oak Common project, specializing in microtunneling works and the installation of launch and reception shafts critical to the diversion of existing utilities to facilitate permanent works. Their scope included the design, excavation, and construction of robust launch and reception shafts that facilitated the microtunneling process for utility ducts and services beneath the site. This involved precise shaft sinking in confined urban spaces, managing groundwater control, and installing temporary works to ensure safe and stable excavation.

In addition to shaft construction, Joseph Gallagher Ltd executed the microtunneling operations, using remote-controlled tunneling equipment to install underground pipelines with minimal surface disruption. Their work demanded close coordination with the main contractors and design teams to meet Network Rail and Crossrail technical standards, ensuring alignment with overall project interfaces. The successful delivery of these microtunneling elements was essential for the integration of critical utility services and structural foundations at Old Oak Common station.
