O&M Cost Model Assurance

01 / The question it answers

Will this operations and maintenance cost model survive diligence?

02 / When clients commission it

Preparing a bid for an O&M concession; before a funder or board decision; when a model has been built by one team and must be defended by another.

03 / What we look at

• the maintenance regime the model assumes and whether the asset supports it
• labour, materials and subcontract build-up
• renewals and lifecycle assumptions
• the risk and contingency position
• the contractual mechanism the model has to survive

04 / What you receive

• a written assurance review identifying where the model is optimistic
• where it is unsupported, and what would be tested first by a diligent reader

05 / Who does the work

Senior principals deliver the work. The person named in the proposal is the person who does the work.

06 / What it does not include

• building the model
• bid management
• bid writing
• any warranty as to the outcome of a procurement
