M1920-18 Structural Repairs - Riverstone, Crowstone Road, Westcliff on Sea

Tender description

The Works and Specification are for remedial works to the external elevations of a six storey medium rise dwelling at Riverstone Flats, Southend-on-Sea, Essex. The property is a purpose built medium rise flat block comprising a reinforced in situ concrete frame with external elevations of cavity infill brickwork. The proposed remedial works primarily involve the introduction of additional expansion joints within the external leaf of infill brickwork around the perimeter facade of the building, to alleviate cracking of the external brickwork fabric. In addition to the above, it is anticipated that stitching of cracks will be required to the brickwork infill panels along with an allowance to undertake remedial wall tie insertion. Concrete repairs will be necessary, primarily to the reinforced concrete parapet, at roof level, along with the exposed floor slab edges. The proposed works will also require the removal and reinstatement of the horizontal expansion joints, at the junctions of the brickwork infill panels and insitu concrete floor slab edges. A provisional item for cavity insulation removal works has also be included. Keywords: Expansion joints, Wall ties, Construction, External cavity infill
