The ICE Demolition Protocol approach requires that material purchase notes should be maintained as evidence of the procurement of recovered materials.
Requirement to Establish Procurement Target
The initial target (prior to assessing cost etc.) for procuring recovered materials will be at least the quantity of materials which could be supplied from demolition and refurbishment. However, the project team must demonstrate that the target for procuring recovered material reflects the potential of the building / infrastructure to accept such materials, unless it can be clearly demonstrated why a lower target is necessary.
Purchase Order Notes & Summary Reports A record should be kept of purchase order notes to provide evidence of the procurement of recycled aggregates for the new build. A summary report should be produced which describes the limitations and opportunities which influenced procurement decisions. For example, the price for concrete with recycled aggregates may fluctuate depending on the availability of separate hoppers, site space and supply.
