Appointed as subcontractor on this new build by Grahams Construction. This new development on Chester Road, Manchester, the Ellesmere Street project created 232 high-specification, living spaces.
Scope of works
Demolition of two office units. (Castlefield and Britannia House)
We were appointed to undertake the demolition works on the site in order to prepare for the new development, Ellesmere Street.
Soft stripping took place by a competent team from Chartrange who were Face Fit Tested, Asbestos Awareness trained and suitably resourced to remove the MMMF, carpets and fluorescent lighting, to be disposed of under the current WEEE Regulations. The identified drainage outlet into the main sewer was temporarily sealed by qualified operatives with Confined Space Entry Risk Assessment and Permit. Electrical disconnections and gas disconnections with purging took place prior to mechanical demolition. Air conditioning units were de-gassed, wet heating system drained down and lift motor hydraulic oil drained off to prevent any pollution issues.
Our Komatsu PC400 LC high reach machine was used for reducing the concrete and brick three story office blocks. A smaller demo spec excavator was used with shears to tackle the 8 tonnes of steel beams in Britannia House, directly adjacent.
