Basahin ang isang FIEBDC-3 presupuesto na ipinadala sa iyo ng iba

Kunin ang BC3 na ipinadala sa iyo ng isang promotor o arkitekto, dalhin ang mga capitulos at partidas nang hindi na ito muling ini-type, tiyakin na ang mga code ay maaari mong ibalik, at manu-manong ibuo muli ang dalawang bagay na dala ng format ngunit hindi ng import.

Paano ito gumagana, hakbang-hakbang

5 hakbang sa buong platform - ano ang gagawin mo sa bawat isa at bakit mahalaga ito.

1

File the file before you open it

Mga Dokumento

Save the BC3 exactly as it arrived into the project files, next to the invitation and the terms it came with. Do not rename it and do not open it in an editor first, because a save from the wrong tool rewrites the encoding and the accents in the partida texts go with it.

Bakit: Presupuestos get reissued, sometimes twice in a week, and the question that arrives later is always which version you priced. A filed original answers it in one click. It also gives you something to compare against when the second file lands and nobody says what changed.

Import the presupuesto as a bill

Bill of Quantities (BOQ)

Import the BC3. Capitulos arrive as sections and partidas as positions, each with its concept code, its unit, the unit rate the sender carried and the measured total. The extended texts fill in the long descriptions, and the encoding is detected rather than assumed, so a file written in the Windows charset that market still uses reads correctly.

Bakit: Retyping a presupuesto of six hundred partidas is where a transposed quantity and a dropped line get in, and neither shows up until somebody prices them. Importing keeps your answer tied to the codes and the wording the sender issued, which is also what lets you hand a priced file back rather than a spreadsheet.

Check the codes you will have to send back

Pagsusuri

Run the bill through validation. The FIEBDC-3 rules ask two things of every position: that it kept a concept code at all, and that the code has a shape the format accepts, which rules out a stray space, a leading dot and the control characters a spreadsheet round trip leaves behind.

Bakit: A position that lost its code prices perfectly well and then cannot be exported back to BC3 without losing the reference the sender uses to find it. That is discovered on the afternoon of the deadline, when the file will not open on their side and nobody can tell you which of six hundred lines is at fault.

Rebuild the descomposicion the import left behind

Mga Assembly

The import reads the decomposition records only far enough to tell an auxiliary resource apart from a real partida, so what you have is a rate without the mano de obra, materiales and maquinaria under it. Pick the partidas that carry your risk and build each one as an assembly with its own rendimientos and resource rates.

Bakit: The sender's unit rate tells you what they expect to pay, not what the work costs you. Rebuilding the twenty partidas that hold most of the money is a morning's work and it is the only version of the number you can argue for afterwards, whether the argument is a baja to justify or a modificado to price.

Write down what you took on trust

Batayan ng Estimate

Record the assumptions the file forced on you. The measurement lines behind each total do not survive the import, so every quantity you did not re-measure yourself is a quantity you accepted from the sender, and that belongs in writing rather than in somebody's memory.

Bakit: A quantity accepted without comment becomes a quantity you warranted. Naming the ones you took as given costs a paragraph now and is the difference between a re-measure and an argument when the work on site turns out to be a third more than the partida said.

The market this case is written for

Spain

Everything in this case follows how construction work is measured, priced and paid for in this market. The forms, the cost breakdown and the payment rules are the ones used there, not a generic version of them.

Standards it follows

  • FIEBDC-3 (BC3)
  • LCSP

You do not have to set any of that up by hand. The first time you open the platform it asks which market you work in. Choose this one and it sets the interface language, loads the matching cost database and records the cost classification, and it adds an example project you can open straight away.
