The challenge

A large, varied estate with no consistent basis for comparison.

Varied building stock

Assets differed widely in age, use and condition across the region.

Assessment without evidence

Recommendations were hard to defend without consistent underlying analysis.

No feedback loop

Delivered savings were rarely checked against what was originally modelled.

Quantaco brought one consistent assessment basis across the region — and tracked delivery back against the modelled case.
