VOB Tender: Creating a Bid

Construction tenders under VOB have specific rules and requirements. This guide helps you create a professional bid.

VOB Overview

  • VOB/A: Procurement rules (below and above EU thresholds)
  • VOB/B: Contract conditions (variations, delays, acceptance, warranty)
  • VOB/C: Technical standards (DIN norms for individual trades)

Construction Calculation

Structure: Direct costs (labor, materials, equipment, subcontractors), site overhead, general overhead, risk and profit. Use GAEB format with AVA software. Patterno BID offers native iTWO integration.

Subcontractors

Submit subcontractor declarations with your bid. Some authorities require minimum self-performance. Obtain subcontractor prices at least 2 weeks in advance.

Alternative Bids

Only allowed if not excluded in the notice. Must be technically equivalent. Can provide competitive advantages through innovative solutions.

Common Mistakes

  1. Unpriced items in the BoQ
  2. Unauthorized changes to the BoQ
  3. Mixed calculations
  4. GAEB transfer errors
  5. Missing subcontractor declarations

VOB tenders require solid construction knowledge and clean calculation. Use professional software and thorough pre-submission checks.
