Plan the final result before the first stage
A phased renovation works best when the eventual layout and service arrangement are understood early. Record which existing problems need priority, which elements can stay in service and which decisions affect later work. This independent CDMX example retains the existing structure; an extension and major structural repairs are excluded.
CONAVI’s technical and maintenance resources treat installations and ongoing care as distinct parts of housing work. Use that broader view when deciding what a stage must deliver. A newly decorated room is not a useful finished stage if its wall must soon reopen for the planned electrical or water route.
Make each stage technically coherent
| Stage | Package amount | Condition before release |
|---|---|---|
| Roof and identified water-entry repair | 38 000 | Cause and method assessed; temporary protection arranged |
| Private service renewal | 56 000 | Final layout coordinated; affected routes accessible |
| Complete bathroom | 64 000 | Service interfaces ready; products and concealed-work checks agreed |
| Other room finishes | 42 000 | Required service work checked; substrates ready |
| Kitchen package | 92 000 | Approved measurements, appliance models and connections |
These are invented final prices including applicable supplier tax. The packages have explicit boundaries: service renewal excludes fixture fitting in the bathroom and kitchen; room finishes exclude those two rooms. Roof work is not a universal first task for every house. An urgent electrical or structural issue may change priorities after professional assessment.
Budget the cost of staging itself
Ask each trade which mobilisation, protection and connection tasks recur. Distinguish costs already inside a package from additional visits caused specifically by the staged programme. Check how long the owner can live without a functioning bathroom or kitchen and whether occupied areas can be safely separated from work.
| Line | Amount |
|---|---|
| Five work packages above | 292 000 |
| Design and coordination outside packages | 10 000 |
| Additional mobilisation caused by staging | 9 000 |
| Temporary kitchen and related arrangements | 5 000 |
| Temporary accommodation | 12 000 |
| Reserve: 10% of work packages | 29 200 |
| Phased funding provision | 357 200 |
The work subtotal is 38,000 + 56,000 + 64,000 + 42,000 + 92,000 = MXN 292,000. The reserve is a planning assumption, not permission for extra work. Without the explicitly additional MXN 9,000 mobilisation line, the same model totals MXN 348,200. Staging spreads payments but does not automatically reduce the total.
Check cash before releasing the next package
Suppose MXN 130,000 is currently available. In this example, the first two packages require MXN 94,000. Add MXN 10,000 design, MXN 3,000 of the total additional mobilisation, MXN 3,000 of the total temporary-arrangement line and hold MXN 10,000 of the reserve: MXN 120,000 is allocated. The remaining MXN 10,000 does not fund the MXN 64,000 bathroom stage.
These allocations are parts of the whole-project provision, not new lines to add again. A smaller current commitment can be sensible, but do not begin a stage assuming later income will arrive before critical payments. Record deposits, lead times and the conditions for delaying an order rather than committing all future funds at once.
Protect the interfaces between stages
Mark temporary pipe ends, electrical arrangements, weatherproofing and surfaces that will be removed later. Have the appropriate specialists define temporary operation and the checks needed before an area returns to use. Keep drawings of the final routes so later trades understand what must be preserved.
Obtain dated offers for the actual sequence. A price valid today cannot be treated as fixed for a package planned much later without agreement. An illustrative MXN 4,000 increase in a later package raises the provision to MXN 361,200 if the reserve is preserved. If it is funded from reserve, the total stays unchanged and the reserve falls to MXN 25,200.
Review the plan at each stage boundary
- Check completion and the agreed technical evidence.
- Record remaining defects and access obligations.
- Reconcile purchases, advances and actual transfers.
- Update later prices and delivery assumptions.
- Confirm temporary living and weather conditions.
- Release the next coherent stage only when scope and funding are ready.
Reno Pro can keep one overall plan with separate stages. Preserve the whole-project forecast even when only one stage is active: it shows the remaining obligation and prevents the first visible improvement from obscuring unfinished services, future purchases or repeated costs.
