Compliance requirements
The machine-readable notice did not include precise exclusion grounds for the bidder; these must be checked in the tender documents. The subcontractor control document also contains exclusion checks for first-tier subcontractors during contract performance, including fraud, tax or social security arrears, bankruptcy or insolvency, suspended business activity, early termination or sanctions in previous public contracts, and false statements or failure to provide required information. These checks apply to subcontractors at the performance stage and do not replace the bidder’s own exclusion review.
