Land fill prices were escalating due to the available sites being filled with materials generated from the many redevelopment activities. In autumn 1986 we bought the first mobile crusher into Birmingham. It was a completely new initiative for dealing with the products that our developing activities produced, i.e. the concrete and hardcore from demolitions and foundation removal. We managed to get the material recovery activity appended to the Waste Management Licence, overcoming objections from Councillors and Residents alike, all of whom when on a site visit were unaware that the machine was actually working. Materials were bought into the yard, crushed, then resold, NOT having to pay for tipping, what a bonus. We soon learnt how to meet Construction Specifications, we installed a magnet to remove the scrap, a screener to remove the side conveyor belt fines from the pre crushed materials, therefore creating more crushed hardcore also a fines material to be used for blinding, we were approaching ZERO waste.
Wates Construction site were to start work on a new site at Aston University Birmingham, where the excavation activities would produce very large quantities of concrete and brick from the substantial foundations and bases of the old buildings that had previously occupied the site. The Bills of Quantities indicated that such materials, allowed for in the Provisional Quantities, would be approximately 75% of the materials to be excavated and removed. The void created by the excavation works was then to be refilled with a piling material to return the site close to existing levels.
We suggested to Wates that we stockpile, process, crush and screen, on site, all excavations that contained artificially hard materials, they agreed but insisted that it would be at our risk and that the programme did not suffer as a consequence, we were to remove all materials that were not compliant with the piling specification, our plan worked, we produced an in spec material, reducing our disposal off site by 60%, saving on 60% of imported stone. We were paid for the excavation, and disposal for the full quantity of materials generated, for the Extra Over Rates for breaking out concrete, brick and the like, then for the provision of piling material. We gave a saving back to Wates, who passed that saving on to the University. This was another FIRST for Coleman.
