Хэрхэн ажилладаг, алхам алхмаар

Платформ даяар 5 алхам - алхам бүрт юу хийх, яагаад чухал болохыг.

1

Set the investment estimate as a rate, not just a total

Ойролцоо төсөв

Build the feasibility number from the building type, the gross floor area and the quality level, and read off the rate per square metre it implies as well as the total.

Яагаад: A total is a fact about a building nobody has designed yet, and a design team cannot work to it. A rate per square metre is a constraint they can test every decision against, which is the whole mechanism of cost-capped design, and it stays comparable when the area moves.

Write down what the approved number assumes

Төсвийн үндэслэл

Record the basis: the scope covered, the standard of finish, the price level and date, what is excluded, and where the rates came from. Keep it with the estimate rather than in the covering email.

Яагаад: Every argument at the next gate is about whether the design changed or the estimate was wrong, and only the basis can answer it. Without one, a stage that comes in over is always explained as a scope change, and there is nothing on either side that can contradict that.

3

Price the design estimate and name the version

Ажил материалын жагсаалт

Price the design item by item against the same scope the basis describes, and save a named version of the bill at the moment it goes for approval so the approved state can be retrieved exactly.

Яагаад: The version that was approved is the only meaningful thing to measure later movements against, and it is unrecoverable a month afterwards unless somebody named it at the time. Naming it costs a moment and turns the next comparison from an argument into a report.

Compare against the approved version at every gate

Ажил материалын жагсаалт

Set the current bill against the version approved at the previous stage and read the difference by section: which items were added, which quantities grew, which rates moved. Work the rate per square metre out again on the current area and put it beside the one you started with.

Яагаад: Nothing here declares a limit or returns a verdict, and that is the honest shape of it: the product shows you where the money went and the cap is held by people. What makes that workable is running the comparison at each gate rather than once at the end, because a section that has grown by six percent is a design conversation while a total that has grown by twenty is a re-approval.

Report the position with the movement explained

Тайлан

Report the stage total, the rate per square metre, the difference against the approved figure and the sections it came from, with a line on each saying whether it was a scope change, a design decision or a price movement.

Яагаад: An approving body asked to consider a number will ask where it came from, and a report that answers that in advance gets a decision instead of a deferral. Naming the cause per section is also what tells the design team where the savings have to come from, which is the only useful output of the exercise.

The market this case is written for

Хятад

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

  • GB 50500
  • GB 50854

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.

The rule checks for this market come with the platform too. Switch them on once and an estimate that misses something the market expects is flagged while you are still working on it, not after the tender has gone out.
