Foyle Road Bridge - Northern Ireland |
|

All the work for this extensive stressing project was carried out inside the box girders of the bridge, with little or no outward sign of the major strengthening work going on inside. Huge steel tubes were permanently installed and pre-stressed to relieve stresses in the support structure and thereby increase the load carrying capacity of the bridge. Our part of the project involved the installation and management of a computer controlled 48 jack system to apply loads of up to 1000 tonnes to the ends of the tubes prior to them being wedged and welded in place.

Wellington Suspension Bridge - Aberdeen |

This listed structure spanning the River Dee, has been undergoing a major overhaul. First built in 1830 to replace the Craiglug Ferry, the bridge was closed to vehicular traffic in 1984. In 2002 it was assessed to be unsafe for pedestrians and a campaign was started to restore the bridge. Our work has involved helping with the replacement of critical link pins at both ends of the bridge. Single strand jacks fitted to special support frames have been used to remove the load on the pins so that engineers could replace them. |

This ramp was built adjacent to the canal near Birmingham's well known Mailbox shopping and office centre. When a new block of flats was built close by, the ramp sank and moved sideways approximately 50 mm. Bill Boley Ltd were contracted to prop the ramp up and move it sideways using 16 vertical jacks and 16 horizontal jacks |
Former Abbey National Building - Baker Street London |

The old headquarters of the Abbey National in Baker St is currently being converted into a block of luxury apartments and the local council stipulated that the bell tower had to be retained in the scheme of the new development. The work on the building, which incorporates the famous (and fictitious) address of Sherlock Holmes's lodging house at number 221b Baker St, has involved complex hydraulic propping in the basement by Bill Boley Ltd to prevent the tower supports splaying out in the clay subsoil. Steel girders have been set at an angle into the ground and15 off 45 tonne hydraulic jacks have been used to pre-tension the outer support frame of the building.
