VSL International Ltd. | Post-tensioning | Structural engineering

A jacking solution developed by CTT Stronghold (VSL Spain) has enabled installation of a series of 45m-long bridge beams where overhead power lines precluded the use of cranes. The 120m-long double bridge on the B-40 motorway at Tarrasa required the jacking of six 325t prefabricated concrete beams. CTT’s operation involved jacking the beams using four climbing jacks each of 90t capacity. |

VSL began work in July 2008 on a nine-storey car park in Monterrey, Mexico. Structural design of the building, including its foundations, has been developed by VSL Mexico. The project uses 36,500m2 of 570mm-thick post-tensioned slabs with 17m spans. Construction lasted just five and a half months, during which time 150t of post-tensioning were installed. |

Spanish expertise in Dublin |
 | CTT Stronghold (VSL Spain) has successfully transported and installed a 1,500t bow string arch in Dublin. The operation used VSL’s skid system together with three 10-axle hydraulic self-propelled modular transporter (SPMT) platforms. The two 60m-long skid lines had skid shoes with 500t capacity vertical hydraulic jacks. |
