Estimate the construction cost
The system uses your state's CUB Sinduscon × area × standard (low, normal or high-end residential, commercial) to calculate the total estimated cost.
All models
Model 04
Pricing based on the real construction value
Fee priced on top of the construction cost
Price projects based on the total construction value, on how the finished build will look, grounded in real data. CUB, SINAPI and market references, no magic formula.
How it works
4 steps from brief to proposal
Set the percentage
The CAU table suggests 5-9% for a complete architectural project. You adjust by stage, preliminary study 1-2%, schematic design 1.5-2.5%, and so on.
SINAPI to budget the build
When you also price the execution, you get SINAPI updated by state for each service. Configurable BDI.
Monthly updates
CUB and SINAPI update automatically, so your proposal never uses an outdated value.
When to use it
Who this model is for
Works well for
- ✓Residential project bundled with construction (same client)
- ✓Client who wants full transparency in the calculation
- ✓Projects where the lot is not defined yet
- ✓When you want to charge for the 'quality of the final build'
Not recommended for
- ✗Renovation where the client supplies all the materials
- ✗Small projects with a very low construction cost
- ✗Client who prefers a 'flat package' with no breakdown
- ✗Projects without clear data on the build typology
In Limify
What changes in practice
CUB always up to date
Monthly integration with Sinduscon by state, so you never use a CUB from 6 months ago.
SINAPI built in
Detailed construction budget by input, with configurable BDI and composition per service.
CAU table as a ceiling
The system shows the CAU table as a reference. You decide whether to charge 5%, 7% or 9% based on your positioning.
FAQ
Frequently asked questions
What percentage of the construction should I charge?
CAU range: 5-9% of the construction cost for a complete architectural project. For small residential builds, some firms charge 10-12% (to offset a proportionally higher fixed cost). For large builds (above R$ 1M), it can drop to 4-6%.
SINAPI or Sinduscon (CUB), which one should I use?
CUB for a quick estimate of the total construction cost (average R$/m² by standard). SINAPI for a detailed construction budget (price per input, composition). Limify uses both: CUB for the fee calculation, SINAPI when you also price the execution.
What if the client does not have a defined lot yet?
You use the average CUB for the build standard they want (high-end residential, mid-range) × the area they want. Once the lot is set and the final area is adjusted, Limify recalculates in seconds. There is no need to redo the proposal, it is an incremental update.
