TGS sub-contracted over 15 road work technicians/specialists who had previous experience in bridge and road construction to a Maltese Joint Venture on the reconstruction of the Manwel Dimech Bridge. This is a major arterial road, and with an estimated 44,000 vehicle crossings per day.

The superstructure (deck) has been designed as a continuous, post-tensioned concrete box girder (one cell) bridge fitted with galvanized steel gratings which allow the drainage of rain water run off through galvanized steel pipes that run within the superstructure deck which eventually discharge into the valley. New bearing pads have been designed to enable replacement during the lifespan of the bridge. 
Following the completion of the demolition phase, the placing of the formwork for the new bridge deck structure commenced. This involved cutting timber sections to shape the new bridge. The concrete casting of the top slab had to be carried out not more than 14 days after the cast of the bottom slab and the side webs. During the placing of steel reinforcement, ducts were placed in the webs of the bridge for the laying of cables. The ducts were placed in the webs vertically in a curved profile through which tendons (cables) were fed and later tensioned so as to accommodate forces generated through the use of the bridge. This being a post-tensioned structure, these cables, of course, play a crucial role in ensuring the structural performance in the lifespan of the bridge. 

Once the formwork was removed, and following the hardening of the concrete surface of the top slab, the waterproofing of the bridge deck commenced. The waterproofing consisted of primary preparation work involving spherical blasting of the concrete surface to eliminate unevenness. In some areas epoxy resin strewed with sand was laid to obtain a smooth surface. At both ends of the bridge, expansion joints were installed so that the structure could accommodate thermal movement and shrinkage of the concrete deck. The scaffolding was removed after a specified number of days following the concrete casting operations and post tensioning of the bridge. .A strict quality assurance programme was set up before the work started with engineers supervising thoroughly the operations of the contractor throughout the projects.
