Prissett et anbud på satslisten som styrer det

Fastslå hvilken satsliste kontrakten er skrevet mot, last inn den som kostnadsgrunnlag, prissett beskrivelsen fra den, og bevis at hver linje bærer satslistens postnummer den kom fra før overslaget forlater pulten din.

Slik fungerer det, steg for steg

5 trinn gjennom plattformen - hva du gjør i hvert og hvorfor det betyr noe.

1

Settle which schedule the contract is written against

Kontrakter

Read the tender conditions and record, against the contract, which schedule of rates governs it, which edition, and what price level it is stated at. Central government work names CPWD DSR; state work names the state PWD schedule; a private client may name neither and leave you on market rates.

Hvorfor: This is the one decision every later number depends on, and it is the one most often taken by assumption. Writing it down where the contract lives means the next person to open the estimate can see which document it was built from, instead of inferring it from the shape of the rates.

Load that schedule as a cost base, not as a column you typed

Kostnadsdatabase

Bring the schedule into the cost database through the ordinary import surface and check it landed with its item numbers, descriptions, units and rates intact. No commercial schedule ships with the product, so this is your own copy or your own cost history, loaded once and reused.

Hvorfor: A schedule loaded as data can be searched, versioned and re-priced next year. A schedule transcribed into a spreadsheet column becomes a set of numbers with no provenance the moment the person who typed them moves on, and every query about a rate turns into an archaeology exercise.

Price the bill and carry the item reference with the rate

Mengdefortegnelse

Work down the bill sub-head by sub-head, from earthwork to external services, pulling each rate off the loaded schedule and keeping its item number on the line. Where no schedule item fits, price it as a non-schedule item and say so on the line rather than bending a neighbouring item to cover it.

Hvorfor: Non-schedule items are normal and are checked differently, by rate analysis rather than by lookup. Marking them at the point of pricing is what lets the department check the rest quickly and concentrate on the few that need argument, instead of treating the whole bill as unverified.

Run the check that finds a rate with nothing behind it

Validering

Validate the priced bill and read the findings. The India pack ships a rule that asks every priced line for its schedule item reference, so the lines you meant to mark as non-schedule and the lines you simply forgot both come back in one list.

Hvorfor: The difference between a deliberate non-schedule item and a forgotten reference is invisible in a printed bill and obvious in a validation run. Finding it here costs a few minutes; finding it after the tender is opened costs a technical query you answer under a clock.

Write down the basis while you still remember it

Kalkylegrunnlag

Record the schedule and edition used, the price level and base date, the lead and lift assumptions, which items are non-schedule and how they were analysed, and what the estimate excludes.

Hvorfor: An estimate on a public job is read months later by somebody who was not in the room, often during a query about a single item. The basis is what turns that from a defence of your memory into a reading of the file.

The market this case is written for

India

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

  • CPWD DSR
  • IS 456
  • RERA

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.
