Number 4 St Paul's Square, Liverpool

From Workstream Pulse, Winter 2015

One of the most significant developments in Liverpool city centre of recent years, the RICS award-winning No. 4 Saint Paul's Square is rated BREEAM "Excellent" for sustainable features such as its 213 square metre sedum roof, water-efficient taps, cycle racks and a lighting system designed to minimise light pollution and reduce carbon emissions by more than 22%. The building provides 10,000 square metres of high quality office space over eight floors and provides a new focal point for Liverpool's central business district.

Wherever possible, main contractor Shepherd Construction used recyclable equivalents to materials that might normally have gone to landfill, ultimately achieving 100% of material being diverted from landfill. (Through its partnership with Tarmac and the White Recycling Group, the company was able to send all waste that could not be recycled to be used as biofuel at a Tarmac plant in Derbyshire.)

Lindner Façades installed the main envelope using a prefabricated and pre-glazed unitised form of construction that eliminated the need for costly scaffolding. Lindner used floor cranes and its own "table method" to enable installation of the façade elements with the slab edge protection remaining in place, providing a safety barrier for operatives and others on site. Workstream provided logistics crew, fixing teams, and supervisory staff to Lindner for the duration of the project.
