From bill of quantities to offer, without retyping or surprises

The crbx, the PDF and the contract do not always agree

After the award it is too late. Ziva lists each finding with line item and source and drafts questions while the forum is open.

In the screenshot

  1. Priority for each finding
  2. Line items concerned
  3. crbx and PDF disagree, with quantities
Bill of quantities check in Ziva: findings on line items and contract documents, each linked to its source.

Unit prices are your craft. Retyping is not.

Ziva carries line items and quantities into an Excel workbook with formulas. Assumptions stay yellow until you set prices.

In the screenshot

  1. Quantity and unit unchanged from the crbx
  2. Yellow: assumptions you replace with prices
  3. Unit price as a formula of material and hours
Excel calculation built from the bill of quantities in Ziva: line items, quantities and formulas, with price cells left empty.

First find out whether you may bid at all

Ziva lists eligibility and award criteria with weight and source before anyone prices a line. You decide.
