Why fit-out tenders take so much time
The contract is decided by the bill of quantities, evidence and formalities, not just the price.
-
Extensive bills of quantities
Bills of quantities with hundreds of pages have to be split up by trade to request quotes from suppliers and to price. That takes days.
-
Formal errors lead to exclusion
If a required declaration or certificate is missing, the bid is excluded under § 16 VOB/A, no matter how good the price was.
-
Evidence is scattered
Certificates, test reports, declarations of performance and references sit on different drives. Every submission starts with searching.

What makes building and fit-out tenders different
Construction contracts follow their own rules. That is exactly where it is decided whether a bid makes it into the evaluation.
Award by trade lots
Under § 5 VOB/A, construction work is generally awarded in specialist and partial lots. Metal construction, windows, facade and drywall are usually separate lots with their own bills of quantities, dates and interfaces to other trades.
Suitability comes before price
Pre-qualification under § 6b VOB/A, references for comparable projects and trade-specific evidence are checked first. In metal construction this often includes certification according to DIN EN 1090.
Bill of quantities as a GAEB file
Bills of quantities often arrive as GAEB files, and the bid goes back in the matching GAEB format. Items, texts and quantities have to be assigned cleanly for this.
Bidder questions have a deadline
In EU-wide construction tenders, additional information must be provided no later than six calendar days before the bid deadline under § 12a EU (3) VOB/A. Unclear dimensions or contradictions with the plans should therefore be spotted early.
Metal construction, windows and doors, facade and interior fit-out: what counts in each
Every trade has its own standards and evidence.
- Metal construction
Structures, railings, stairs
For load-bearing components made of steel and aluminium, certification according to DIN EN 1090 with a matching execution class is usually required, plus welding certificates and structural documents.
- Windows, doors & gates
Declaration of performance and protection classes
Required are declarations of performance according to DIN EN 14351-1 or DIN EN 13241, thermal transmittance values, burglar resistance according to DIN EN 1627 and, for fire doors, the building authority approval.
- Facade & interior fit-out
Fire protection, sound insulation, statics
DIN EN 13830 applies to curtain walls. In drywall and interior fit-out, fire classification, sound insulation according to DIN 4109 and references for comparable projects count.
