Longleat House is one of Britain's most important stately homes and best examples of Elizabethan architecture. When the roof had to be removed for significant maintenance work, it was vital to provide appropriate weather protection to protect important artefacts in the house. The challenge was to find a moveable scaffold solution that would completely cover 25% of the roof at any one time and withstand all weather conditions.
Only the HAKITEC 750 system met all the demanding requirements of this grand scale project, enabling the repairs to proceed as planned. The contractors, TR Services, said the moveable design of the roof was "a huge advantage and worth every penny" and that HAKI's technical support was "simply invaluable".
HAKI worked with TR Services to develop the optimum solution and trained their scaffolders to ensure that they fully understood the product and its erection procedure. HAKI also supported TR Services by sending an Instructor to site when the roof was erected to ensure that it went smoothly.
The roof was 22m wide by 40m long with a 21m clear span. It was supported on a scaffold system that used 22 miles of tube and fitting. The total scaffold solution took 6 weeks to erect - 5 weeks for the outer scaffold and 1 week for the erection of the roof and installation of the sheeting.
Stuart Salmon, TR Services Managing Director commented: "We looked at a number of systems and there were cheaper solutions in the market place but we found HAKI offered a technically superior product and a number of value added services which, when combined, were really essential to us. On this project the superior support offered by the HAKI team has been invaluable. This, in addition to the fact that it has fewer components, helped our scaffold team with familiarisation of the product and reduced the overall installation time."
- The design of the rolling track and the efficiency of the nylon wheel meant that moving the roof to a new position took only 15 minutes.
- Designed to withstand 28 tonnes of snow and a windloading of 30 tonnes of down force and 41 tonnes of uplift.
- To cope with the profile of the existing roof, the temporary roof was designed and constructed with an "offset ridge".
- Unique HAKI Trak joint method ensures a very effective weatherproof seal.
