<\/div>Description of the project<\/h2><\/div>Bachy Soletanche Group Limited<\/a> was part of the integrated consortium which was awarded Contract 811 A (Express Rail Link). The scope of works comprises the construction of a 300 metre long cut-and-cover tunnel in a dense urban environment.<\/p>\n<\/div>Our solution<\/h2><\/div>During the first phase, advanced utility and traffic diversion works were completed. In particular, a viaduct was completely dismantled and rebuilt at a different location. In the second phase, the geotechnical works which comprised an excavation of a 240,000 cu. metre “box” of 30 deep metre, was carried out. The third and last phase consisted in building the permanent reinforced concrete underground structure inside the diaphragm wall<\/a> and a building to accommodate the mechanical and electrical rooms. The main technical difficulty of the project lies with the crossing of the existing metro line. This imposes a very specific sequence of works and limits the allowable settlement and displacements.<\/p>\nThe existing line being founded on barrettes socketed into the rock, BSGL has proposed to re-use them to support the newly built structure. The final task, the load transfer from the old to the new structure, was a very delicate operation.<\/p>\n<\/div>
