What was included in your pre-tender estimate for Dyson D9?
What’s the main purpose of a cost plan?
To control affordability of design
Ensure clients are provided with value for money
To provide robust information so the client can make informed decisions
Why do we include assumptions and exclusions?
Statements for clear or ambiguous information
What constitutes a cost plan?
Building works
Main contractors prelims
Main contractors OH&P
Risk allowances
Design/project team fees
Other project costs
Inflation
What is included for project design fees?
- Consultants (based on %)
- Pre construction (% or lump sum)
- Main contractor design fee
What is the purpose of a cost estimate?
To ensure affordability
To break the costs into elements
To agree a cost limit
When are estimates carried out in the RIBA plan of works?
Stage 0 - feasibility estimate
Stage 1 - order of cost estimate
Stage 3/4 - pre tender estimate
What information is required for a cost estimate for building services?
- Indicative specifications

What is included within ‘other costs’
Costs not directly associated with the building but needed for the development
