Speaking at NCE's Waste Summit last week, Bovis Lend Lease senior sustainability manager Nick Clarke said subcontractors would no longer be able to include waste in their prices.
"Previously wastage was incorporated into a subcontractor's price, but now we need them to estimate and quantify how much waste they think will be created by their work," said Clarke.
"This will enable us to look at ways of cutting waste early on. It will also give us something more fixed to monitor our progress against, to let us know how close we are to achieving that 70% reduction aspiration."
Efforts to reduce waste is driven at a local level by cost savings, said Clarke. Implementing waste reduction measures and site waste management plans might cost tens of thousands of pounds. But savings in materials costs and landfill charges are likely to amount to hundreds of thousands of pounds he added.
At a global level, Bovis' parent company Lend Lease wants to be seen as a green firm worldwide and is listed on the Dow Jones Sustainability World Index.
This includes more than 300 companies that represent the top 10% of the leading sustainability driven companies among the biggest 2,500 companies in the Dow Jones World Index.
Other firms on the index include Amec and Ferrovial.
The demand from Lend Lease for all its businesses to be sustainable, said Clarke, was the driver behind Bovis' aspiration to cut waste (at 2007 levels) by 70% by 2010. It wants to be seen to be doing more than the minimum – in this case the Government's aspiration to halve construction waste in the UK by 2012.
