Alerts at 80% and 100% of BOQ

Deviation control for BOQ contracts

See executed against BOQ quantity for every item, live from site measurements, so you seek approval before the work is built, not after it is billed.

Deviations known before the bill. Item by item, from site.

Warns at 80% of BOQ

An alert reaches the billing engineer and project manager as each item crosses 80%, then 100%.

Questions

What billing engineers ask about deviations and extra items.

Contact the billing team

Can we change the 80% and 100% alert levels?

Yes. Set them per work order or per item. Some contractors add a 90% alert on high-value items.

Does Tatha Vastu stop work beyond BOQ quantity?

No. Site work goes on. Entries beyond BOQ are held out of the bill until you record the approval reference.

Which deviation limit does it use?

The one written in your contract, entered once per work order. Tatha Vastu flags items as they approach it.

How is an extra item's rate worked out?

You enter the rate analysis: from the schedule of rates where the contract says so, or from market rates with the overheads and profit your contract allows.

Does the deviation statement match our client's format?

Yes. It uses the client's columns and order, and exports to Excel and PDF with the bill package.
