BREEAM Pre-Demolition and Pre-Redevelopment Audits
Pre-demolition and pre-redevelopment audits/surveys are a requirement of the BREEAM 2011 WST01 Construction Waste Management Standard as well as BREEAM UK Refurbishment and Fit Out 2014 in attaining credits by promoting resource efficiency via the effective management and reduction of construction waste.
The overall aim of the PDA is to demonstrate sustainable construction and redevelopment via your BREEAM assessment and achieve your required target rating ranging from good-outstanding.
These audits are undertaken on existing buildings, structures and hard-standing surfaces prior to demolition or redevelopment and are an important sustainability tool for understanding whether existing key demolition products (KDPs) and building elements can be incorporated into the redevelopment of the site.
By understanding what the building is made up of, estimations of weights and volumes are undertaken with the key goal of maximising recovery and diverting materials from landfill by following the order of the waste hierarchy:
- Prevention
- Preparing for Reuse
- Recycling
- Other Recovery
- Disposal
By following these waste hierarchy principles, an assessment of materials will be undertaken to promote resource efficiency in the aim of reducing the environmental impact of the project. Recommendations will be made to minimise construction waste by incorporating the reuse of materials and even saving on overall costs.
The Pre-Demolition and Pre-Redevelopment Audit Process
Prior to the audit, Revive will analyze any information received relating to the project which can include original architect drawings, structural plans or demolition /refurbishment drawings.
Following this, a non-intrusive investigation of the internal and external areas of the site will be made using appropriate measuring tools.
This information is collated within Revives bespoke software calculating estimated weights and volumes of Key Demolition Products (KDPs) which will include the building structure, roof and internal building fabric (excluding furniture) as well as external elements like hard-standing surfaces, fences and outbuildings.
Overall, Revive will provide recommendations and advice on the maximum potential reuse and open/closed loop recycling options to minimise construction waste.
Working in accordance with the BRE Pre-Redevelopment Waste Audit Code of Practice, Revive will incorporate the following steps within the PDA:
Collection and examination of received information
Site Audit
Estimation of types and amounts of materials
Assessment of the suitability of materials for reuse/recycling/other waste management methods
Recommendations for materials management, recycling and target setting
The identification of practical and realistic providers who can act as brokers for each of the reclaimed items
This will in turn support the principal contractors site waste management plan in managing materials from the demolition/refurbishment process and ensuring recovery is in line with the waste hierarchy.
For Pre-Redevelopment Audits, these assessments are undertaken as per the proposed scope of redevelopment/refurbishment works as opposed to the demolition of the whole building.
