Audits.
On-site surveys and material cataloguing for every stage of your project — from pre-application through to in-use buildings.
PDA
Pre-Demolition Audits
Before you build or demolish
A pre-demolition audit is a detailed survey conducted prior to deconstruction, refurbishment or demolition. Carried out by independent third-party specialists, the audit reviews buildings, structures, hard surfaces and FF&E to produce a full catalogue of components and materials with key product information, embodied carbon data, and suitability for reclamation and reuse.
MRA
Material Reclamation Audits
Maximise recovery, minimise waste
An MRA maps materials scheduled for removal, assesses their condition, volume and reuse potential, and creates a plan to divert them from landfill. It reduces embodied carbon and recovers residual financial value from materials that would otherwise be wasted.
PRDA
Pre-Redevelopment Audits
Retention before demolition
Conducted early in the design process, a PRDA provides independently verified analysis of the potential to reuse or adapt existing assets before demolition is considered. It forms a key evidence base for circular economy strategies and planning applications.
ERI
Extended Resources Inventory
In-use building assessment
An Extended Resources Inventory is an audit conducted during the in-use phase of a building. It verifies the current financial value of building resources and provides guidance on maintaining that value during future deconstruction. The ERI covers resources belonging to the asset owner, excluding tenant-owned fittings and furnishings.
MP
Material Passports
Digital material identity
Every material catalogued on the MI platform receives a digital passport with provenance, condition, environmental data, and reuse suitability — giving buyers and specifiers the confidence to procure reclaimed.
