Why a checked BOQ
What it costs to bid without one.
Published research, with the source on every card. Tap a card to see it.
Your bid
US$ 15,000
lost on one bid, from quantity errors
That is 38% of your US$ 40,000 margin. The client does not pay for missed quantities. You do.
How Sidoku helps: every line is measured from the drawing and checked by a Licensed PE before you price it.
Source: Worked example
Illustrative arithmetic: 3% Γ US$500,000 = US$15,000, against an 8% margin of US$40,000. Your own tender and margin will differ.

megaprojects run over budget
Nine out of ten megaprojects run over budget. Overruns of up to 50% in real terms are common.
