What gives renovation in stages
The 'What to do in one phase must' covers:
- technical scope of each phase
- repeated mobilizations, supplies and security
- temporary arrangements to use apartment
How to set stage boundaries
Before counting, collect: measurements, initial condition, expected standard, work sequence and list of elements remaining unchanged.
Basic unit of settlement: material scope described by quantity, unit, standard and performance conditions.
What needs to be done together
The greatest influence has:
- number of stages and length of breaks
- can installations and substrates be logically separated
- availability of the same crews and materials in subsequent dates
Recurring costs
In the cost estimate, separate separately:
- technical scope of each stage
- repeated mobilizations, deliveries and security
- temporary solutions enabling the use of the apartment
The "set" item without a description makes it difficult to compare and later settle the topic "What to do in one stage necessarily."
How to calculate the cost of staging
Stage cost: sum of technical scopes + multiple mobilizations + additional security and cleaning + price increases or differences in material batches.
Logistics, delivery and security
The most frequently missed are:
- re-containment and clean-up
- lot variations and re-minimum orders
- damage to finished zones during next step
Where staging helps you save
Reasonable savings:
- combine dirty and installation work into one step
- close an entire room or logical range instead of individual activities
Accept savings only after checking whether they do not shift the cost to labor, waste or later repairs.
When phasing increases cost
Do not cut costs with:
- on the continuity of waterproofing, installation and substrate
- on securing previously completed elements
How to control the whole
For "What must be done in one stage" keep a table: base scope, changes, orders, payments and estimated cost until the end. Each change should have a price and impact on the deadline before approval.
Common errors
- 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
Assessment of the organization of stages
Schedule 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.
