ساخت smeta بر پایه هنجارهای GESN با روش منبعی

مجموعه هنجاری را که قرارداد نام می‌برد بردارید، هر هنجار را به مصرف نیروی کار، ماشین‌آلات و مصالحی که حمل می‌کند باز کنید، این منابع را به قیمت روز قیمت‌گذاری کنید و آن‌ها را به‌صورت lokalnaya smeta ثبت کنید، تا هر نرخ تا هنجاری که از آن آمده باز شود.

چگونه کار می‌کند، گام به گام

7 گام در سراسر پلتفرم - کاری که در هر گام انجام می‌دهید و چرا اهمیت دارد.

1

Pick the norm collection the job is priced on

پایگاه داده هزینه

Open the cost database and choose the collection the job is actually priced on: GESN when you will price the resources yourself, FER when a federal unit rate governs, TER when the region has approved its own territorial rates. Record the edition alongside it, because a norm number is only unique inside its edition.

چرا: GESN and FER are two readings of the same federal norm base, published together as FSNB, while TER are the territorial equivalents a region approves for its own territory. GESN carries physical consumption and no prices, FER and TER carry rates already priced in base year money. Starting on the wrong one is not a rounding error: it decides whether the resource method is open to you at all, and whether state expertise will accept the result.

2

Expand each norm into the resources it fixes

نُرم‌های تولید

Open the norm and read what it contains: man hours by trade grade, machine hours by machine type, and the material quantity per unit of measure. Adjust a quantity only where the technical part of the collection allows it, and write down the clause you relied on next to the change.

چرا: The consumption inside a GESN norm is the state's statement of what the work takes, and it is the half of the price nobody is free to invent. A resource quantity moved without the technical part behind it is the first thing an expertise reviewer writes up, because it can be spotted without recalculating anything.

3

Price the resources at current money

کاتالوگ منبع

Give every resource a price: the hourly wage for the grade in this region, the machine hour rate with the operator in it, and the material price from your own quotes delivered to site rather than ex works. Keep the source and the date on each price.

چرا: This is the step that makes the method resource based rather than index based. A price without a named source cannot be defended when the customer asks where the figure came from, and a price without a date cannot be re-based when the job runs into the following year.

Compose the work you repeat into assemblies

اسمبلی‌ها

Where the same combination of norms and resources comes back section after section, save it once as an assembly with its own unit of measure, so the next section and the next project start from it instead of from the norm list again.

چرا: A smeta of several thousand positions cannot be kept consistent line by line, and inconsistency between two identical items in different sections is exactly what a reviewer picks up. An assembly also carries the reasoning with it, which is what lets a second estimator take over your file without rebuilding it.

Post the positions into the lokalnaya smeta

صورت مقادیر (BOQ)

Enter each priced position with its quantity from the takeoff, grouped into sections the way the working drawings divide the work, and keep the norm number, the unit of measure and the resource-built rate on every line.

چرا: The lokalnaya smeta is the document every summary above it is built from: object smetas sum the locals and the svodnyy smetnyy raschet sums the objects. A wrong quantity or a wrong norm number here is wrong in every summary above it, and the summaries are what the customer actually reads.

Apply NR and SP on the base each is calculated from

صورت مقادیر (BOQ)

In the bill's Markups & Overheads panel, apply the Russian template to bring in the national stack in its order, overheads (NR), estimated profit (SP), the reserve line and NDS, then set the NR and SP rate for each type of work from the norms rather than leaving one rate on the whole bill. Read what each line is applied to: the shipped template carries NR and SP as an effective percentage of direct cost, because a bill markup can take direct cost or the running total as its base and payroll is neither.

چرا: The norm sets NR and SP against payroll, worker wages plus machine operator wages, and by type of work, not against the position total. An effective percentage of direct cost keeps the bill total right for a typical work mix and wrong in its sensitivity, so on a bill whose labour share is far from typical rebuild the markup on the resource decomposition rather than trusting the line. Applying either to material or equipment cost inflates the smeta in a way a reviewer finds by arithmetic alone.

7

Read the resource summary the method produces

خلاصه منابع

Open the summary the smeta rolls up to: total man hours, machine hours by machine type and material quantities by nomenclature across the whole estimate, and read it against what the job plausibly needs in crews, plant and deliveries.

چرا: The output of the resource method is not only a total in roubles. The same summary is what the works schedule, the crew plan and the material procurement are built from, and it is the norm baseline that the M-29 material reconciliation will later compare actual consumption against.

The market this case is written for

روسیه

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

  • GESN/FER
  • KS-2 / KS-3

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.
