CONTENTS
Introduction
Demolition contractors, designers and new build contractors should work together in planning the demolition works to be undertaken.
Planning can start at the design stage when designers consider the feasibility of on site reclamation; more detailed plans can be then completed as soon as the demolition contract has been awarded.
This page sets out issues to be taken into account when planning demolition works. More detailed information is available in Section 10 of "The efficient use of materials in regeneration projects".
Material arisings, demand and contamination
- A pre-demolition audit should have provided estimates of the type and quantity of materials arising and this can be used in a Site Waste Management Plan. This will also provide information on the type of equipment needed for demolition works.
- The demolition needs to be planned to obtain materials that best match the type and quantity of materials needed in the new build. If expected arisings exceed the needs of the project, the demands of the local market should be taken into account.
- The team should consider potential contamination issues, including hazardous materials and consequent potential health and safety issues: guidance is available from the ICE Demolition Protocol.
- The project team should agree data collection methods, e.g. through Waste Transfer Notes or stockpile surveying, to measure KPIs. These methods are likely to be similar to those used for complying with SWMP regulations.
Site and operational issues
- Demolition works should be undertaken with equipment capable of generating the right type of outputs.
- On site storage of demolition arisings may be impossible because of lack of space and in this situation the establishment of a temporary processing/storage facility nearby should be explored. Guidance on related issues such as site organisation and environmental permitting are available from AggRegain.
- An assessment should be undertaken of off site and on site materials transport with the aim of minimising truck movements as much as possible.
- The health and safety of operatives and the public may influence the extent to which materials are recoverable, for example due to hazardous contamination or accessibility issues.
