West Point, Manchester
JPG were appointed to carry out a structural survey on the 16-storey central Manchester office block. The survey also included an adjacent multi-storey car park.
The structure is a typical 1970s construction, comprising an insitu concrete frame with masonry cladding. Typically in construction of this era, the outer brick skin was supported at floor level by a slab edge boot which was masked with brick slips. A combination of creep shrinkage of the concrete frame structure and thermal expansion of the brickwork, caused the floor level movement joints to compress and the brick slips to become dislodged.
The survey of the main structural principles was carried out primarily by reference to record drawings. The survey of the external fabric was carried out by external inspection via a combination of maintenance access cradles and abseiling.
Detailed recommendations were made for a regime of maintenance and repair to ensure that the structure continues to serve as quality office space.
