Stonewest previously carried out the refurbishment and cleaning of the stonework to Selfridges, a Grade II Listed building, in 2000.
Key Successes
- Loss of building fabric from high level leading to the development and erection of a bespoke designed scaffold erected off the first floor cill and cantilevered at high level to provide protection from falling materials and an inspection/working platform for further works; carried out in normal working hours over Oxford Street and the surrounding streets.
- Stonework and steel work investigations at high level both internally and externally to the building. Removal of key elements of the fifth-floor cornice to examine patterns of corrosion and reasons for loss of fabric.
- Following examination of the steelwork, development through trials and design of a bespoke extensive Cathodic Protection system to protect the steel work from corrosion in key areas of the fifth-floor cornice. Design of fixings to support modillion stones and design and introduction of a secondary system of steel beam supports to carry the huge cornice stones of the original 1909 section of the building where the original steels could not be guaranteed.
- Major stone masonry repairs and replacement incorporating gravity grouting of voids with hydraulic lime mortars and pointing of joints.
- General cleaning using Doff system and Hodge Clemco abrasive clean to decorative steel panels at high level, to investigate fixings and potential paint schemes.
- Installation of new lighting scheme and provision of new lead and asphalt.
