- PIRs.
[- Green roof.]
[- Energy efficient heating and cooling.]
OVO Arena - a) How were the works presented to your client in the PPM?
b) How were the sustainability works presented?
a) - Schedule [condition and year for each item].

- PPMs outline the maintenance over reporting period (typically 10 years).
TDD: - Compliance.
- Property sale not maintenace.
For D&B what RIBA Stage would you take the design to?
RIBA Stage 3 - Spatial Coordination.
What’s the difference between Building Regulations and British Standards?
- Building Regs: minimum standards (mandatory).
- British Standards: best practice (voluntary).
How are provisional sums dealt with post-contract?
- Provisional sum and works omitted.
- Contract instruction issued with defined works and cost [variation not CI if the cost differs].
[PS amount is deducted from contract sum and actual cost of instruction/variation is added]

- DoW [Description of Work].
- The site.
- The contract.
When is planning permission required?
Not required for:
- Internal works.
- Permitted development.
- New build.
- Change of use.
- Extension.
How long does planning permission take?
- Typically around 8 weeks for normal property.
- Around 12 weeks for Listed building [both LBC and normal planning considered together].
What information is required when submitting a planning application?
- Site plan.
- Existing and proposed drawings.
- Application form.
