1. What the current tools are
The description in professional sources shows a division that follows company size. Larger firms use software, smaller ones spreadsheets.
Larger construction companies use various software solutions to simplify and speed up the calculation of quantities, but most construction companies work classically by hand. According to professional sources, the software used for measuring quantities recognises drawings in DWG, IFC and PDF formats.
The tools therefore exist, but their use is uneven, and that unevenness matters for the market. The gap carries into the comparability of tenders.
2. What software solves
Three things, and the third is underrated. It concerns keeping track of revisions.
| What it gives | When it counts |
|---|---|
| Speed of measurement | especially with repeating elements |
| Fewer arithmetic errors | addition and multiplication are automatic |
| Fast recalculation of the effect of a change | when the design changes |
The third matters particularly in reconstruction, since the design changes often: with a manual calculation, every design change means repeating part of the calculation. Tracking variations then becomes hard.
3. What software does not solve
Four things remain for a person to decide, and the fourth is the most important. Software does not replace them.
| What remains with the person | Why |
|---|---|
| Choosing the measurement rule | see measurement rules |
| Choosing the technology | how the work is actually carried out |
| Material consumption norms | they require knowledge of technology and materials |
| Noticing omissions | seeing what is not on the drawing |
Software measures what is on the drawing and does not know what is missing. A wrong or incomplete drawing gives the same wrong result with software, only faster.
4. What it presupposes
Two conditions must be met, and they tie pricing to design. Without them the calculation stays imprecise.
The drawings must be in machine-readable form, that is DWG or IFC, or at least in correct PDF form, and where the IFC format is used the model must have been built consistently. Software cannot read quantities from a scanned or hand-drawn document.
The practical conclusion for a client is broader than a question of software: a sound design is a precondition not only of building but also of pricing. The quality of the design sets the quality of the tender.
5. What that means for the market
Three consequences, and the third is the most practical conclusion in this article. It concerns the field of participants.
A larger company tenders faster and can take part in more procurements, while a smaller one has to choose, which reduces competition in each procurement. A common schedule of quantities levels that difference entirely, because then neither of them calculates.
A client who provides the quantities receives more tenders, including from smaller companies. Competition widens.
Summary and four practical rules
Larger construction companies use software that reads DWG, IFC and PDF drawings to calculate quantities, but most companies work by hand. Software speeds up measurement, reduces arithmetic errors and allows the effect of a change to be recalculated quickly, but it does not choose the measurement rule or the technology and does not notice omissions. It presupposes machine-readable drawings, which ties the quality of pricing to the quality of design.
Four rules: do not assume software replaces knowledge of technology. Check for omissions yourself, since software does not see what is missing. Ensure machine-readable drawings if you want fast and precise pricing. Provide the quantities if you want tenders from smaller companies too.
