WJ can offer a wide range of solutions required to provide a dry and stable excavation, with experience working in confined areas and next to live railway lines. As metro and underground railway lines are often constructed within built up areas where access can be restricted, consideration for mobilising to site, care of neighbouring structures and services, and selection of appropriate plant, equipment and materials are a must. WJ are used to working in challenging conditions, and working closely with Main Contractors, Consultants and Clients to meet specifications and programmes.
