Renovation budgets drift when the scope drifts. This guide describes how to keep both under control from the first brief to handover, including how to treat unknown conditions.
What causes scope creep
- A brief that was never written down.
- Decisions made late, after work has started.
- Extras agreed verbally and never priced.
- Hidden conditions that were not planned for.
A sequence that keeps control
- Brief: record the outcome, priorities and constraints.
- Site review: verify existing conditions and note unknowns.
- Scope and specification: define what is in, what is out and what is provisional.
- Planning: sequence, access, approvals and responsibilities.
- Progress checks: compare work and cost against what was agreed.
- Handover: close items and keep the records.
Separating essential from optional
Ask for essential work to be priced separately from optional upgrades. If the budget tightens, the optional items can be reduced or deferred without disturbing what must be done.
Handling unknown conditions
Plan for unknowns by naming them and agreeing how they will be handled, rather than assuming they will not occur. A contingency approach should be agreed with the client, based on the age and condition of the property, not applied as a fixed percentage by habit.
Questions clients ask
What records protect both parties?
The written brief, the agreed scope, approved changes, site instructions and inspection records.
How can essential work be prioritised?
By safety, risk of further damage, operational impact and the cost of delay, with optional upgrades listed separately.
