Client: Rhondda Cynon TAF
Project: Porth Relief Road, Station Street Bridge
This project involved the replacement of an existing failed bridge structure with a new Matiere Opti–Cadre 12,5metre x 6 Metre precast buried concrete box structure. This was an alternative to the specimen design which effectively reduced cost and construction programme. Off–Site construction helped to minimise resources devoted to other complex structures on the project.
This solution is a highly developed installation process using highly skilled in–house construction teams to lift heavy precast components around intricate and complex temporary propping system for the support of lateral abutments in the construction phase.
Five Days completed the installation of the entire bridge structure including the precast box and the retaining wing––walls extending on four sides up to 38metres in length.
The client obtained the lowest possible whole life cost solution with a saving in excess of 33% compared to the alternative bridge deck and abutment solution.
