What you need to know about site waste management plansWhat is a SWMP?A SWMP sets out how resources will be managed and waste controlled at all stages during a construction project.A SWMP covers: Who will be responsible for resource management. What types of waste will be generated. How the waste will be managed – will it be reduced, reused or recycled? Which contractors will be used to ensure the waste is correctly recycled or disposed of responsibly and legally. How the quantity of waste generated by the project will be measured.
Who is affected by a SWMP?SWMPs affect anyone who is: planning or delivering a construction project in England with an estimated construction cost of over £300,000 working on smaller projects in England and want to follow industry good practice planning a public sector construction project valued at more than £200,000 in Northern Ireland planning a project for which your client or planning authority requires a SWMP a supplier to the construction industry.
Why do you need a SWMP? To comply with the law – All projects in England with an estimated construction cost of over £300,000 must have a SWMP before work begins. To protect the environment – SWMPs help to manage and reduce the amount of waste produced by construction projects, which means less waste goes to landfill. Other environmental benefits include less damage to the local environment, less fly-tipping, lower energy use and greater use of recycled materials. To save you money – Managing your materials more efficiently immediately cuts costs. Better storage and handling reduces waste and makes it easier for materials to be recovered. Reusing materials on site will cut your disposal costs.
What are the benefits of a SWMP? Save time – You can answer queries about your waste from your environmental regulator or local council quickly and easily. Help you avoid prosecution – You can easily make sure all your waste is disposed of legally. Win new business – You can prove your environmental performance, which can give you an advantage in the tendering process. Understand and reduce waste disposal costs – You understand how your waste is managed so you can identify where to save money and reduce costs. Enhance your reputation – Your customers can see where you are helping the environment and making cost savings. Help the environment – You will manage materials and waste on site more responsibly so they are less of a risk to the local environment. Improve future projects – When your SWMP is complete you will have useful information for future projects about how you used resources and managed your waste.
Site waste – the facts: The average 8 cubic yard skip costs around £150. The average cost of what is being thrown away in that skip is over £1,600. The cost of waste can be as much as £43/m2 in typical construction projects. 10m tonnes of construction products are wasted every year, at a cost of £1.5 billion.
Simple steps to help you create your own plan Step one – Plan and prepare Step two – Allocate responsibility for the SWMP Step three – Identify your waste Step four – Identify how to manage your waste Step five – Identify where and how to dispose of your waste Step six – Organise your materials and waste Step seven – Communicate the plan and carry out training Step eight – Measure your waste and update your SWMP Step nine – Review the success and learn lessons for the future

Reducing Waste through Off Site Construction Off site construction has a range of benefits compared to traditional build including the potential to greatly minimise on site waste. Through the substitution of a range of off site construction methods there is the potential to reduce on site wastage by up to 90%. Although some waste will be transferred to the factory environment, the amount will be significantly reduced. In this environment there can also be greater opportunities for reuse or recycling.
Kings Cross Eastern Goods YardThe Kings Cross development is the largest mixed use scheme inEurope. The 67 acre site will incorporate premium office area, newhomes, retail, hotels, serviced apartments, student accommodation,leisure, health, cultural, community, education and other uses. It isestimated that the project will take 15 years to complete.The Site Waste Management Plan includes details of the waste to besegregated for recycling. The aim is to divert 70% of all wasteproduced on site away from landfill; andThe percentage of recycled content of construction components wasmeasured using the WRAP Recycled Content Toolkit. Thisengagement aimed to demonstrate that a 10% target for recycledcontent is readily achievable. Davis Langdon carried out a summaryassessment of the project which showed a baseline recycled contentlevel of 22%, with a potential increase to 26.5%.
