Reconcile materials on form M-29

Take the norm consumption for the work the month actually completed, set it against what the store really issued, separate allowed losses from real overrun, get each overrun explained in writing and close the month with the cumulative position.

Cómo funciona, paso a paso

7 pasos a lo largo de la plataforma - qué haces en cada uno y por qué importa.

1

Take the norm consumption for the work you are reporting

Normas de producción

For each position in the report, take the material consumption the norm fixes per unit of measure, and note which material the norm actually names, because anything substituted on site has to be converted to the normed material before it can be compared at all.

Por que: The first section of M-29 is the normative requirement, and it is derived rather than stated: the quantity of work multiplied by the norm per unit. Taking it from the norm instead of from last month's figure is the whole reason the comparison means anything.

2

Separate the losses the norm allows from real overrun

Factores de desperdicio

Set the allowance for trimming, offcuts, breakage and transport loss for each material, so the difference between what was purchased and what was built into the work reads as a known figure rather than as an unexplained gap.

Por que: Part of the difference between norm and actual is not overrun: it is loss the norm already contemplates or that the delivered form of the material imposes. Mixing the two makes every position look like a problem, and a report in which everything is a problem stops being read.

3

Fix the volume of work the month actually completed

Avance

Record the quantity of each type of work completed in the reporting month, measured in the same units and by the same rule the smeta uses, because this quantity is what the whole normative requirement is calculated from.

Por que: M-29 compares consumption against the norm for the work done, not for the work planned. An overstated volume hides a material overrun completely, which is exactly why the same measurement has to feed both the KS-2 act and this report rather than being produced twice.

4

Record what was really issued and consumed

Inventario de obra

Book the deliveries in, the issues out against each work position and the returns, then close the month with a physical stock check, so consumption means what left the store for that work rather than what was bought during the month.

Por que: Purchased is not consumed. Material standing on site at the end of the month belongs to the next report, and treating a delivery as consumption produces an alarming overrun in one month and an impossible saving in the following one, which is how the report loses its credibility.

5

Compare actual against norm position by position

Postcálculo

Set the actual consumption against the normative requirement for each material and each position: the post-calculation reads the material money the estimate allowed against what the store issued for the quantity installed, line by line, and the stock ledger behind it gives the physical difference per material. Sort the result by money rather than by percentage.

Por que: The second section of M-29 is exactly this comparison, and its value lies in being read by position. One concrete or reinforcement line can carry more overrun in roubles than every other position together, while a cheap material with a dramatic percentage swing costs almost nothing and pulls the whole discussion away from where the money went.

6

Get every overrun explained and signed for

Rutas de aprobación

Route each overrun above the agreed threshold to the person who has to explain it, with the reason written down, and on to the person who has to accept or refuse that explanation. Keep the refused ones visible rather than closing them.

Por que: An overrun on M-29 is not written off by the site that caused it. The form is drawn up by the site manager, checked by the production and technical department and approved by the chief engineer, and that approval is what turns a number into either an accepted cost or a matter for recovery. Without a route, the explanation is a corridor conversation that nobody can produce six months later.

EntradaOverruns above thresholdWritten reason from the siteResultadoAccepted explanationsRejected and referred on
7

Close the month with the cumulative position

Informes

Issue the report with both sections, the normative requirement and the comparison against actual, with the explanations attached, and show the position from the start of the job next to the position for the month.

Por que: A single month is noise, the cumulative line is the finding. A position running three percent over every month for six months is invisible monthly and unmistakable cumulatively, and that cumulative figure is also what reconciles against the material cost the estimate budgeted in the first place.

The market this case is written for

Rusia

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.
