- risks that can be identified before launch
- uncertainty of the state of hidden layers
- price volatility and the cost of decisions changed in during
What determines its level
Before counting, collect: measurements, initial condition, expected standard, order of work and a list of elements remaining unchanged.
Basic unit of settlement: material scope described by quantity, unit, standard and performance conditions.
Known and unknown risks
The greatest influence has:
- age and technical identification of the premises
- number of installations and missing works
- completeness of the project and detailed valuation
How to separate the reserve from the basic budget
In the cost estimate, separate separately:

How to set a starting point
Starting point: a well-recognized development finish usually requires less reserve than an old premises without open pits. As a guide, you can consider about 5-10% with low uncertainty, 10-15% for a typical renovation and 15-25% with many unknowns. This is a working buffer, not a universal standard.
What should the reserve not be spent on
The most often omitted are:
- failure or defect revealed after disassembly
- need to replace a larger scope than planned
- cost of temporary protection and displacement schedule
How to protect the reserve
Reasonable savings:
- do not spend the reserve on raising the standard before closing the risks
- release part of the reserve only after acceptance of the stages revealing the technical condition
Accept the savings only after checking whether they do not shift the cost to labor, waste or later repair.
When to increase the reserve
Do not cut costs with:
- on removing the cause of the failure
- on installations, waterproofing and elements affecting safety

- comparing only amounts without comparing the scope
- lack of reserves for waste, supplies and open-pit works
- change of the standard after ordering or commencement of work
- recognizing the reserve as free funds for extras
Budget Security Ratings
Reserve check and next step
Prices and availability vary over time and regionally. Compare quotes with the same expiration date, tax, payment terms and completion date.
Next step: write down the quantity, standard and three largest unknowns, then request a comparable quote or update the budget sheet.
