Cost benefit case study: Trade package containing blocks, insulation and bricks
This cost benefit analysis is based on the design stage of a structual blockwork trade package including insultation and facing bricks. The analysis is carried out per £100k spend. The study found that there was a total potential saving (net of implementation cost) of 7.37%.
Cost benefit analysis focusing on dense concrete blocks and facing bricks, with mineral wool insulation batts.
The case study consists of calculating the potential costs and benefits of carrying out waste management good practice during the design stage of a trade package containing dense concrete blocks and facing bricks, with mineral wool insultation batts.
The Net Waste Tool is used to identify the top opportunities to reduce and recover waste and to estimate the cost savings from implementing these measures.
Key points
Clients need to instruct designers to look for waste reduction opportunities, plus set threshold waste reduction and recovery targets.
Designers need to look for opportunities to design out waste (such as simplification of the specification).
Contractors need to develop a quality SWMP and a materials logistics plan.
Trade contractors need to ensure that materials are not over ordered, and that the materials brought to site are used as efficiently as possible.
The waste management contractor must ensure that all wastes received are recycled wherever possible.
