Site waste management plan outline for demolition and rebuild

A site waste management plan outline for a demolition and rebuild has to do three things: forecast what the project will produce, set targets for diverting it from landfill, and show how the duty of care will be discharged on every load that leaves. The forecast comes from a pre-demolition audit. Everything else follows from that audit, which is why the plan cannot sensibly be written before it.

The statutory requirement disappeared in England years ago. The documents did not, because planning conditions, environmental assessment schemes and client sustainability requirements all ask for them.

Why the plan survives the revoked Regulations

The Site Waste Management Plans Regulations 2008 were revoked in England, so there is no longer a general legal duty to prepare a plan for projects above a cost threshold.

What replaced it is a patchwork that catches most projects anyway:

• planning conditions requiring a waste plan to be submitted and approved before commencement
• environmental assessment schemes that award credits for waste diversion backed by a plan
• local plan and supplementary planning document policies on construction waste and the circular economy
• client and funder requirements, particularly in the public sector
• the waste hierarchy duty, which applies to anyone transferring waste regardless of any plan

The underlying obligations never went anywhere. The duty of care under the Environmental Protection Act 1990 applies to every transfer, and the waste hierarchy duty under the waste regulations requires you to take reasonable measures to apply prevention, preparing for reuse, recycling, other recovery and disposal in that order.

So treat the plan as the document that organises compliance rather than as a regulatory relic. A Site Waste Management Plan written to discharge a condition and then filed does nothing. One used on site changes what the project costs.

Pre-demolition audit inputs

The audit is a survey of the existing building to establish what it is made of, in what quantities, and what condition those materials are in.

A usable audit records the building's construction by element, the estimated quantity of each material by weight and by volume, the condition and reuse potential of each, the presence and location of hazardous materials, any items of salvage value, and the access and sequencing constraints that affect how material can be separated.

Weight matters more than volume for reporting, because diversion targets and transfer documentation work in tonnes. A plan forecasting in cubic metres and reporting in tonnes cannot be reconciled afterwards.

The audit is also where reuse opportunities are identified, and they are usually lost by default. Structural steel, bricks in lime mortar, roof slates, flagstones, timber joists and architectural features all have value and all need a decision early, because a demolition contractor pricing a programme for speed will not preserve them.

Where a Pre-redevelopment Audit is already being prepared for other reasons, it should feed the waste plan directly rather than sitting as a separate document that nobody cross-refers.

Waste streams, forecasts and targets

Set out the forecast as a table by stream, with the estimated quantity, the intended management route and the destination type.

Targets should be expressed as a diversion percentage by weight, with a separate target for reuse on site if that is realistic. Say how the figure was arrived at. A target copied from a policy document without reference to the audit is a number nobody will meet or measure.

Two things improve forecasts quickly. Separate the demolition phase from the construction phase, because they behave completely differently. And forecast excavation arisings separately, since their volume dwarfs everything else and including them flatters the diversion percentage without changing any behaviour.

Reuse and recovery on site

On-site reuse is the top of the hierarchy that actually gets achieved on demolition projects, and the main route is crushing inert material for use as fill or sub-base.

That requires space, a crusher, and a legal basis for using the material without it being treated as waste. The industry quality protocol route and the exemptions regime both have conditions, and using processed material outside those conditions turns a saving into an offence. Set out in the plan which route is being relied on and who is responsible for the paperwork.

Other on-site opportunities worth stating explicitly: topsoil stripped and stored properly for reuse in landscaping, crushed brick as a growing medium in biodiversity features, timber reused for site hoarding and temporary works, and salvaged material retained for the new building where the design allows.

Space is usually the constraint on a tight urban site, and that constraint should be acknowledged in the plan rather than papered over with an aspirational target.

Carriers, consignment notes and duty of care

This is the compliance spine of the document and it is short.

1. Check that every waste carrier is registered, using the public register, and record the registration number and expiry.
2. Check that every receiving site holds the appropriate permit or exemption for the waste it is taking.
3. Describe waste accurately on the transfer documentation, with the correct classification code.
4. Keep waste transfer notes for two years and hazardous waste consignment notes for three.
5. Reconcile the returned documentation against the forecast monthly, not at the end.
6. Name the person responsible for each of the above.

The monthly reconciliation is the step that gets skipped and the one that makes the final report possible. Chasing a year of transfer notes from a subcontractor who has left site is a miserable exercise.

An illustrative outline

Illustrative only. A plan for a demolition and rebuild of a two-storey commercial building might run in this order: project details and responsibilities, a summary of the pre-demolition audit, the hazardous materials register and removal arrangements, the forecast by stream with quantities and routes, diversion targets and the basis for them, on-site processing and reuse proposals, segregation arrangements and site layout, carrier and facility checks, documentation and record keeping, monitoring and reconciliation, then a closing section comparing actual against forecast. Eleven sections, with the forecast table and the reconciliation table doing most of the work.

Hazardous materials and asbestos

Hazardous material handling sits partly outside the waste plan and has to be cross-referenced to it.

A refurbishment and demolition asbestos survey is required before demolition or major refurbishment, and licensed asbestos removal work must be carried out by a contractor licensed by the health and safety regulator. The survey, the removal plan and the consignment arrangements all belong in the plan by reference, with the detail in the specialist documents.

Beyond asbestos, watch for lead paint and lead flashing, fluorescent tubes and lamps containing mercury, refrigerant gases in cooling plant, oil-filled equipment, fuel tanks and their residues, treated timber, and contaminated soil from historic uses.

Each hazardous stream needs a named carrier, a licensed destination and a consignment note. Mixing a hazardous stream into general waste is the single most expensive mistake available on a demolition site.

Reporting actual against forecast

The plan's final section is the one that justifies everything before it, and the one most often left blank.

Report by stream, showing the forecast quantity, the actual quantity, the route taken and the diversion percentage achieved, with the transfer documentation referenced. Then explain the variances. A stream that came in at twice the forecast tells the next project something useful, and a diversion target missed with a stated reason is more credible than a target reported as met without evidence.

Where a condition requires the completed plan to be submitted, submit it with the documentation summary attached. Where it does not, keep it anyway, because it is the evidence base for the next audit and for any environmental assessment credit claimed.

The construction phase arrangements overlap heavily with the Construction Management Plan, so write them once and cross-refer rather than producing two slightly different versions of the same site layout.
