Our waste strategy covers design, construction and operational phases of the building process.
Whether it be a refurb or a new build on an existing site, we draw inspiration from Circular Economy, LEED and BREEAM guidelines to ensure we not only meet but where possible exceed industry benchmarks.
Focus areas include salvaging and re-using any physical assets pre-development, designing to minimize the creation of waste in demolition and then construction, as well as design strategies that minimize natural resource depletion.
For 68 King William Street for example, we worked to identify waste streams upfront as part of the pre-refurbishment audit to maximize diversion rates from landfill. Reusing the existing facade, structure and roof also equated to less reliance on virgin resources.
During construction, responsibility largely lies with the contractor to develop a Site Waste Management Plan and then monitor its subsequent implementation, demonstrating its impact with waste carriage records.
Again, for 68 King William Street, we worked with our Sustainability Consultants Twin & Earth to develop specific targets for the contractor, in this instance a minimum of 85% by volume or 90% by weight of the construction waste 90% by volume or 95% by weight of the demolition waste was to be sent to recycling. The total construction waste generation was capped at 11.3m3/100m2 or 3.5 tonnes/100m2 of GIA for the office areas.
The constructor is also made responsible for the waste management is delivered by recognised, specialist carriers.
Looking ahead, our role in reducing operational waste at 68 King William Street will be in providing convenient, easily accessible recycling facilities.
