Description of the works
Demolition and site clearance of all the buildings and link bridge (with the exception of the Grade 2 Listed Building located to the west side of the site entrance) including the grubbing up of all ground slabs and foundations. All suitable arising’s to be crushed and stockpiled; any further material to be recycled / disposed from site.
The former works consist of 4 buildings; stone built with a combination of flat and pitched roofs, corrugated cement roofs and glass and plastic highlights, a portal framed building and a link bridge. There is a further Grade 2 listed building which is to remain.
A culvert runs through the mill with running water which is fed from the canal. The approximate line of the culvert will be marked out on the floor and care will be taken when working near or passing over this area as it is to remain undamaged and in operation on completion of the demolition and site clearance work. Banksman will assist with the manoeuvring of plant and equipment at all times.

Demolition
Following the removal of ACM’s and soft strip out of the interiors of the structures, all salvageable roof slates where stripped off prior to demolition. The four buildings in the photographs were demolished top down by mechanical means using hydraulic excavators fitted with a selection of attachments.
The listed building (which had to be protected during the demolition work) was connected to a building to be demolished by a link bridge which had to be carefully separated and removed. The main structure of the Link Bridge comprises of 2 no. deep steel girders at the bottom, the floor being timber planks and the remaining covered walkway is constructed from timber with felted roof coverings. The Link Bridge will be removed by holding the structure with the high reach hydraulic excavator whilst being detached from the buildings and lowering it to the floor. All timbers, felt etc. to the link bridge were stripped away using hand tools; the remaining steelwork and the timber floor had to be cut free from the adjacent structures using oxy propane cutting equipment during which the high reach excavator held the structure steady and in place with certified chains.
The site of Wrigley Mill on the northern part of the site and the site of the 1863 iron foundry of the loom works in the southern part of the site is of historical interest. An Archaeological watching brief during the demolition works was carried out by ‘The Jessop Consultancy’.
Waste Summary
We aim for 0% to landfill although there is usually a small amount of general waste on all sites.
