Clayton Hotel

Scope of Work: Working closely with the structural team CCUK designed and installed an exact and complexed combination of both CFRP, Shear Bolting and steel, providing a Hybrid Solution for a multi-faceted strengthening solution.

There was a significant increase of imposed loads on the existing structure due to an extension adding additional stories and bedrooms to the Hotel. Strengthening was required to existing columns, shear walls, beams for hogging and sagging in addition to slabs for punching shear. The hotel remained live during the strengthening works which included working in closed rooms, corridors, restaurants and service kitchens.

This was a complexed structural refurbishment project, requiring close working with the designer and main contractor C-Field Construction.

Columns in the existing restaurant were strengthened for additional axial load by adding hoop layers of Fibrwrap carbon fibre strengthening system, the final application had a 2hr fire protection system before decorative finishes.

Shear walls were strengthened with CFRP within the fire exit stairs and existing restaurant for additional vertical loadings and a new opening through.

Beams within bedrooms and live corridors were strengthened using the carbon fibrewrap system, works were carried out in the live hotel with control measures in place.

Punching Shear strengthening was attempted using stainless steel shear rods but due to the congestion of the reinforcement within the slab CCUK specifically designed a carbon fibre solution in conjunction with WSP Consulting Engineers. CCUK also manufactured and installed the shear brackets to column/slabs in several bedroom areas.

CCUK, used the analysis done by the engineer to design a Fibrwrap CFRP and steel ‘Hybrid’ strengthening system. The subsequent ‘design strategy’ enabled the successful application of our solution in all affected areas, whilst the hotel remained fully functional.

CCUK delivered another quality project for two of our top clients, on time and to budget. We would like to thank Graham Construction and HTS for their continued, ongoing support.
