Alexander Street Retaining Wall No 0899, Alexander Street Tyldesley, Improvement Works Contract 2018

Tender description

Alexander Street Retaining Wall is a gravity stone retaining wall structure with a solid brick parapet. It is approximately 2.2m high from the footway and the parapet is approx. 1.2m high. The structure forms the southern boundary of house Nos. 17 - 43 Alexander Street, It is a private wall, jointly owned by owners of the these properties. The retaining wall is approximately 2.2 metres high from lower ground level (this figure varies slightly along the wall's length) and the parapet wall is a further 1.2 metres high. Following General inspection by Wigan Council and found to be bulging and contained various structural cracks along its length, a principal inspection was carried out in April 2016 by an independent Consultant, confirming that the wall did need some works to make safe. These works will involve underpinning the existing wall working in short lengths and casting an insitu reinforced concrete wall, adjacent to the existing wall, rebuilding the missing 20 metres of brickwork parapet and repointing the existing parapet along the whole length.
