Die NBR-12721-quadros für eine incorporação einreichen

Messen Sie die vom Standard definierten Flächen, bauen Sie den custo global für den padrão des Gebäudes auf, stellen Sie ihn dem veröffentlichten CUB gegenüber, erzeugen Sie die quadros, tragen Sie die Kosten über die fração ideal auf jede Einheit, und stellen Sie das memorial für die Registrierung zusammen.

So funktioniert es, Schritt für Schritt

6 Schritte über die Plattform hinweg - was Sie bei jedem tun und warum es zählt.

1

Measure the areas the way the standard defines them

Massenermittlung

Take off the private, the common and the total real area of every unit, then convert them into the equivalent area of construction the way NBR 12721 prescribes, so that covered and uncovered work are weighted rather than added. Keep both sets of figures, because the quadros ask for both.

Warum: Every figure downstream is a rate multiplied by one of these areas, so an area computed the ordinary way rather than the way NBR 12721 defines it is wrong in the same direction on every unit and in the registered document. Corrections after registration are a rectification at the registry office, not an edit.

Build the custo global for the padrao you are building

Kostendatenbank

Price the building at the standard of finish it is actually specified to, keeping the structure, the finishes and the services apart, and separate what the standard treats as the building from what it treats as land, licences and marketing. Read out the cost per square metre of equivalent area.

Warum: The rate per square metre is the figure everyone compares, and it only means anything when the numerator and the denominator were built to the same rules. Costs that do not belong to the construction inflate the rate and make the building look expensive against every published reference, which is a conversation with a bank rather than with an estimator.

Place the rate against the published CUB

Preisindex

Load the CUB published for the state and the building type that matches yours, put your rate beside it, and write down what the difference is made of: the items the CUB expressly leaves out, such as foundations, lifts and external works, and the specification choices that are genuinely yours.

Warum: The CUB is computed under NBR 12721 for a standard project and deliberately excludes several real costs, so a building priced honestly is expected to sit above it. What has to exist is the sentence saying by how much and why. Without it, the same gap reads to a buyer or an auditor as a padded cost rather than as foundations.

Produce the quadros in the form the standard prescribes

Berichte

Generate the numbered quadros NBR 12721 lays out, from the areas of each unit through to the cost of construction and its distribution, and check that the same total appears identically in every quadro that carries it. Keep the reference month of the cost on every sheet.

Warum: The quadros are read by a registrar who checks them against each other rather than against the building, so an internal disagreement between two sheets stops the filing even when both figures are individually defensible. Generated from one source they agree by construction, which is the only reliable way to make a set of twelve tables consistent.

Carry the cost onto each unit by its fracao ideal

Projektentwicklung

Distribute the construction cost across the units in proportion to the fracao ideal recorded for each one, and hold that distribution beside the sale prices so the margin on a small unit can be read separately from the margin on a penthouse.

Warum: A development sold at one price per square metre across every unit is usually selling the ground floor at a loss and does not know it, because the cost per square metre is not flat once parking, terraces and common areas are allocated. The filed distribution is the only version of that arithmetic both the buyer and the developer are looking at.

Assemble the memorial de incorporacao for registration

Dokumente

Bring the quadros together with the title, the approved drawings, the licences and the technical responsibility notes into the set that goes to the registry office, and keep the filed version untouched afterwards as its own record.

Warum: Lei 4.591 of 1964 makes registration of the memorial the condition of selling units that are not built, so this set is what allows the sales to start, and every buyer contracts against the version that was filed. A working copy that keeps evolving in the same folder is how a later dispute finds two memorials, and only one of them is the one anybody agreed to.

Der Markt, für den dieses Fallbeispiel geschrieben ist

Brasilien

Alles in diesem Fallbeispiel folgt der Art, wie Bauleistungen in diesem Markt aufgemessen, kalkuliert und abgerechnet werden. Die Formulare, die Kostengliederung und die Zahlungsregeln sind die, die dort gelten, und keine allgemeine Fassung davon.

Standards, denen es folgt

  • Lei 14.133
  • SINAPI
  • ABNT NBR 12721

Das müssen Sie nicht von Hand einrichten. Beim ersten Start fragt die Plattform, in welchem Markt Sie arbeiten. Wählen Sie diesen aus, und sie stellt die Oberflächensprache ein, lädt die passende Kostendatenbank, hinterlegt die Kostengliederung und legt ein Beispielprojekt an, das Sie sofort öffnen können.

Die Prüfregeln für diesen Markt sind ebenfalls dabei. Einmal eingeschaltet, fällt eine Kalkulation, der etwas Marktübliches fehlt, schon während der Arbeit auf und nicht erst nach der Abgabe.
