When a Brazilian developer hands over a unit after the 180-day grace period set in the sale contract, every extra month costs 1% of everything the paying buyer has already paid.
7The rule is in Law 4,591/1964, art. 43-A, § 2, added in 2018. The person whose job is to make sure that calculation is never needed is the COO.
The acronym stands for chief operating officer. In Brazil the seat usually goes by diretor de operações, and in smaller companies the job falls to a partner who is an engineer.
This text describes the seat as IncorpBuilding sees it, from the developer's side: whoever buys the land, approves the design, sells off-plan and promises a delivery date. The reading is IncorpBuilding's, marked as such; the laws cited are listed in the references at the end.
A development is born on paper: land, design, budget, schedule, price list. Until the launch, the work is deciding. After the first sale, the work is delivering.
The law is clear about what must be delivered. The design and the specification form part of the construction contract, and the contract "must state the delivery date of the works and the conditions and forms of any extension" (Law 4,591, art. 48, §§ 1 and 2).
The COO receives that promise already signed. On every site of the company, the seat answers for four things: time, cost, quality and safety. It answers for all four at once, because they pull in opposite directions.
Speeding up costs money and raises the risk of accidents. Saving on materials threatens quality. Fixing defects eats time. The seat exists to arbitrate those trade-offs with judgement, every month, not to pick one of the four and sacrifice the others.
In IncorpBuilding's reading, what sets the COO apart is the plural. A good engineer runs one site. The COO makes several sites move together, competing for the same technical team, the same cash and the same suppliers, without one site saving its schedule at the expense of another.
Each site has its own technical lead. Every contract to carry out engineering works is subject to the Technical Responsibility Record, the ART, and it is the ART that "defines, for legal purposes, the technical leads of the project" (Law 6,496/1977, arts. 1 and 2).
The resident engineer lives on his or her site: the day's work fronts, crews, quality of the work, safety on site. The general coordinator puts time, progress and risk of all sites into a single picture. The site administrator runs the back office: staff, documents, local purchases, controls.
The COO decides what none of them decides alone: where the reinforcement goes when two sites need it, which front stops when material runs short, which supplier leaves the list, when a delay stops being recoverable and has to be escalated.
Above the COO, the CEO runs the whole company and the execution of the whole. In structures that have a CVO seat, that seat looks after the long term and the course: which product to launch, in which city, with how much risk. The COO does not set the course; the COO executes and delivers within it.
The division is one of roles, not of territory. The CEO may answer directly for one or more sites, as a partner or as the person responsible for the contract; when that happens, the COO supports those sites as part of the whole, with crews, supply and indicators, without taking that responsibility away from the CEO.
| Seat | Answers for | Does not decide |
|---|---|---|
| Resident engineer | His or her site: work fronts, crews, quality and safety on site, under an ART | Reinforcement that takes people or money from another site |
| General coordinator | The picture of all sites: time, progress, risk, alerts | A change of priority between sites without the board |
| COO | Time, cost, quality and safety across all sites | Which projects to launch and how much capital to put at risk |
| CEO | The whole company and the execution of the whole, in the present and the short and medium term | The long-term course, where a CVO seat exists |
Since 2018, the law has accepted a buffer. Delivery up to 180 calendar days after the scheduled date does not allow the buyer to undo the deal and triggers no penalty, provided the grace period is in the contract "clearly and prominently" (Law 4,591, art. 43-A).
Once the buffer is used up, the cost appears. A buyer who did not cause the delay may terminate the contract and get back everything paid, plus the contractual penalty, within 60 days (§ 1).
If the buyer prefers to keep the unit, he or she receives on delivery 1% of the amount actually paid for each month of delay, pro rata by day (§ 2). The two penalties cannot be added together (§ 3).
The law goes beyond the contract. The developer is civilly liable for carrying out the development and compensates buyers for losses caused by failing to complete the building or delaying it without justification, with the right to recover from the builder if the fault lies there (art. 43, II).
And there is an extreme limit. If the works stop for more than 30 days without just cause, or move far too slowly, a judge may order the developer to resume them within at least 30 days; if the order is ignored, an absolute majority of buyers may remove the developer (art. 43, VI).
In IncorpBuilding's reading, the 180-day grace period is not planning slack. It is insurance against the unforeseen. The internal schedule aims at the contractual date; whoever plans already counting on the six months meets the unforeseen with no insurance at all.
The physical and financial schedule pairs two curves: how much of the building is finished each month and how much is spent to get there. When the two move together, the site is under control. When spending runs ahead of progress, something is costing more than planned.
The COO works the schedule at three distances. In the long term, the whole site, month by month, up to delivery. In the medium term, the next six to eight weeks, with what must be bought, contracted and cleared for each task to start.
In the short term, the week: what each crew does, where, with which material. The week shows whether the month's plan is real.
Inside the schedule there is a chain of tasks that admits no delay: foundations, structure, walls, building services, finishes, each waiting for the previous one. That is the critical path. A day lost on it is a day off the delivery date; a day lost elsewhere can usually be absorbed.
That is why the COO's weekly question is always the same: did the critical front of each site produce what it should? Productivity, here, is simple arithmetic: quantity of finished work divided by the crew hours spent. When productivity on the critical front falls, the delivery date slips.
The group's builder, C&S Engenharia, writes from the other side of the counter, the side of whoever executes. Both sides look at the same schedule with different questions: one asks whether delivery is secured; the other, whether production pays for itself.
The segregated estate regime (patrimônio de afetação) ring-fences the land, the works and the funds of one development from the rest of the company, for a set purpose: completing the development and handing over the units (Law 4,591, art. 31-A).
For operations, the most visible effect is reporting. The developer gives the buyers' representative committee, at least every three months, a statement of the state of the works and how it matches the agreed timeline or the funds received in the period, "signed by qualified professionals" (art. 31-D, IV).
The general rule for developments sold at a fixed price and date repeats the quarterly duty, comparing the state of the works with the delivery date (art. 43, I, a).
Whoever reads those reports may also look at the site up close. The committee and the bank financing the construction may appoint, at their own expense, an inspector to monitor the segregated estate (art. 31-C). The appointment transfers to the bank or the committee no responsibility whatsoever for the quality of the works or the delivery date (§ 1).
In practice, the COO answers to three readers of the site: the buyer, through the committee; the bank, through the inspector; the board, through internal indicators. In IncorpBuilding's reading, all three receive the same number, taken from the same schedule. A site with one version for each reader no longer has a version anyone can trust.
Money follows the same logic. The law requires the developer to preserve the funds needed to finish the works (art. 31-D, III). The CFO runs the cash calculation; the COO delivers the physical measurement that says how much is left to build.
No critical front moves without material and without a crew. Material arrives through supply management, which buys on the timeline of the medium-term schedule. It is kept and controlled by the storekeeper, who checks what comes in and records what goes out.
The COO's role is to set the standards: which items are bought centrally for all sites, how much lead time each family of materials requires, what tolerance is accepted on receipt.
The workforce comes, to a large extent, from execution contracts: a construction contract with a builder, subcontracts for specific trades. The Civil Code has three rules the COO needs to know by heart.
First: whoever measures and does not complain within 30 days accepts. What was measured is presumed verified if, within that period, the owner or the inspector does not point out defects (Civil Code, art. 614, § 2).
Second: design changes are requested in writing. The contractor may only charge extra for changes that result from the owner's written instructions, unless the owner, present on site, knew and never objected (art. 619).
Third: whoever hires is jointly liable for the site's social security contributions. Developer, owner, builder and subcontractor are jointly liable, with no benefit of order (Law 8,212/1991, art. 30, VI). Checking payments before paying is an operations routine, not a finance detail.
The law puts safety in the company's name. "The company is responsible for adopting and using collective and individual measures for the protection and safety of the worker's health", and must give detailed information about the risks of the operation to be carried out (Law 8,213/1991, art. 19, §§ 1 and 3).
Failing to comply with safety rules is a criminal misdemeanour (§ 2). An accident must be reported to Social Security by the next working day and, in case of death, immediately (art. 22).
When there is negligence regarding safety rules, Social Security recovers from the company, through a recourse action, what it paid to the injured worker (art. 120, I). And payment of the benefit does not remove the company's civil liability (art. 121).
On site, the tool is the Risk Management Programme, the PGR, mandatory on every construction site (NR-18, item 18.4.1). It replaced the former PCMAT, which remains valid only until the end of the works where it already existed (item 18.17.1).
The PGR is drawn up by a professional qualified in occupational safety and "implemented under the responsibility of the organisation" (item 18.4.2). It must keep pace with the stage the works are in (item 18.4.3.1). And each contracted company hands over the inventory of the risks of its own activity, which goes into the site programme (item 18.4.4).
NR-1 sets the order of measures: first eliminate the risk; then collective protection; then the organisation of work; only last the personal equipment (item 1.4.1, g). In IncorpBuilding's reading, the COO makes sure that order holds when the schedule gets tight too, because that is exactly when it tends to be reversed.
A delivered building remains a construction matter for a long time. The contractor who supplies materials and execution is liable for five years, a period the contract cannot shorten, for the soundness and safety of the building; the owner has 180 days from the appearance of the defect to file suit (Civil Code, art. 618).
For those who buy as consumers, the Consumer Protection Code adds further layers. The builder is liable for damage caused by design or construction defects "regardless of fault" (art. 12).
The buyer has 90 days to complain about an apparent defect, counted from delivery; for a hidden defect, the period only starts when the defect shows up (art. 26). And a claim for damage caused by the defect is time-barred after five years (art. 27).
Together, these rules lead to an operational conclusion. The cheapest defect is the one found with the wall still open. Inspecting before covering pipes, waterproofing and structure costs hours; the same defect found after delivery costs rebuilding inside someone's apartment.
Delivery does not end with the keys either. After the occupancy permit, the developer must register the construction at the land registry and is liable for losses caused by delay (art. 44 of Law 4,591). The COO puts that step in the schedule, with an owner and a date.
Too many indicators hide what matters. In IncorpBuilding's reading, six are enough for the board to follow operations across several sites.
The last indicator closes the loop. The defect that appears in a delivered building shows what inspection on the site in progress let through.
Next to the indicators sits the map of execution risks: foundations different from the soil survey, rain during the structure phase, a single supplier for a critical item, a shortage of skilled labour. Each risk has an owner, a warning sign and an agreed response. The map goes up to the board when it changes, not only when it becomes a problem.
The example is hypothetical. The assumptions are the author's, chosen to keep the arithmetic simple, and do not describe a real development. A development has 60 buyers up to date with payments, who paid on average R$ 300,000 each by the delivery date. The contract includes the 180-day grace period, and the works will exceed it by one month.
Keeping the site open, with technical team, site facilities and equipment, costs R$ 220,000 a month (assumption). The alternative is to recover the month with overtime on the critical front.
| Assumption or result | Accept the month of delay | Recover with overtime |
|---|---|---|
| Amount paid by buyers up to date (60 × R$ 300,000) | R$ 18,000,000 | R$ 18,000,000 |
| Compensation of 1% a month on the amount paid (art. 43-A, § 2) | R$ 180,000 | zero |
| Site kept open one more month (assumption) | R$ 220,000 | zero |
| Overtime: 40 people, 2 h a day, 22 days, for 4 months | zero | 7,040 h |
| Cost of an overtime hour (assumption: normal hour of R$ 30, plus 50%) | zero | R$ 45 per hour |
| Total | R$ 400,000 | R$ 316,800 |
The hours: 40 people times 8 hours times 22 days give 7,040 normal hours a month. Two extra hours a day add 1,760 hours a month, or 25% more. Over four months, that 25% recovers a full month of work, if productivity holds.
The 7,040 overtime hours at R$ 45 cost R$ 316,800. Brazilian labour law caps overtime at two hours a day and requires it to be paid at least 50% above the normal hour (CLT, art. 59).
The difference is R$ 83,200, and the figure favours overtime because of an optimistic assumption: a tired crew produces less and has more accidents. That is why the arithmetic does not decide on its own.
What it shows is something else. The choice only exists four months ahead. Found in the last month, the delay has no cheap remedy left, and the COO can only choose between paying the compensation or rushing the works at the moment of greatest risk.
There are three situations in which a separate seat weighs more than it helps.
First: the developer runs one site at a time. With no sites competing for crews and cash, the responsible engineer and the CEO cover operations, and a COO would have little to arbitrate.
Second: all construction is contracted out as a turnkey contract with a builder, and the developer only inspects. What is missing then is a good contract inspector, not an operations director. Liability towards the buyer, however, stays with the developer, which only has recourse against a builder at fault (art. 43, II).
Third: the company is between cycles, with land under approval and no works under way. The seat can wait for the next launch, as long as someone already answers for after-sales service on what has been delivered.
In every case, what cannot be missing is the function: someone with a name and authority answering for time, cost, quality and safety. The title matters least.
The CEO runs the whole company and the execution of the whole, and may answer directly for specific sites. The COO answers for operations across all sites: time, cost, quality and safety, also supporting those that sit with the CEO. In structures that have a CVO seat, the long-term course stays with it; the COO executes and delivers within that course.
Only when it is agreed in the contract clearly and prominently. In that case, delivery up to 180 days after the scheduled date neither lets the buyer undo the deal nor triggers a penalty. After that, a buyer up to date with payments may terminate the contract or receive 1% of the amount paid per month of delay (Law 4,591, art. 43-A).
No. The representative committee and the bank financing the construction may appoint, at their own expense, someone to inspect and monitor the segregated estate. The law states expressly that this appointment transfers no responsibility for the quality of the works or for the delivery date (Law 4,591, art. 31-C, § 1).
For new works, the required document is the site PGR, set out in NR-18 and drawn up by a professional qualified in occupational safety. A PCMAT that existed before the current rule remains valid until the end of the works it refers to. In both cases, implementation is the company's responsibility.
The Civil Code sets five years of the contractor's liability for the soundness and safety of the building, with 180 days to file suit after the defect appears (art. 618). The Consumer Protection Code adds its own periods for apparent and hidden defects and five years to claim compensation for damage.
