Location: Lime Street, Liverpool
Client: Liverpool Vision for Liverpool Council
Client’s Project Manager: Martin Stockley Associates
Timescale: July 2008 to March 2009
Scope: The soft-strip, deconstruction, demolition and site clearance of a 14-storey office building and adjacent shops and basements. Site directly outside main city centre railway station with busy streets on other sides.
The fourteen storey tower block was made up of a reinforced concrete column grid with flat slab floor construction and glazing & steel board cladding. Adjacent to the tower block was a row of two storey shops with basements. The site was outside the main city centre railway station in Liverpool (Lime St) with the shops directly up against the front station wall.
Full height scaffolding was erected to all floors with monarflex sheeting and boarding to the top lifts. The top floors were deconstructed using mini-diggers and bobcats with debris deposited down the lift shaft. The lower floors were demolished using an Hitachi EX800 long reach demolition excavator fitted with a concrete pulverisor and 360o rotation once the scaffolding had been dismantled. The demolition was carried out above a live sub-station in the basement of the tower block, which was protected by waterproofing and reinforcing the ceiling prior to demolition.
The demolition material arising from the work was crushed on site and compacted down in layers over the footprint of the site. This material formed the base for the follow-on works to create an attractive public realm space at the entrance to the station.
During the project the site was also audited externally and received the NFDC’s Accredited Site Audit Scheme as well as surpassing the requirements of the Considerate Contractors’ Scheme.
“I would like to place on record our appreciation for the work Forshaw Demolition carried out on this challenging project, which was undertaken to the highest of standards, in particular regard to the consideration of the station’s operation. In particular I would like to take this opportunity to congratulate Forshaw’s team for the successful completion of the demolition works and thank them again for their efforts in maintaining harmonious relations with the station and its team. – Samantha Hadnum, Scheme Project Manager, Network Rail
