Reconciliar os materiais no formulário M-29

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 quê: 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.

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 quê: 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.

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 quê: 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.

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 quê: 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.

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 quê: 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.

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 quê: 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.

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 quê: 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.
