Design and technical specifications tailored to preferred bidders
Design requirements and technical specifications are drafted to advantage specific suppliers or technologies, reducing competition and increasing cost and lock-in.
Red Flags & Indicators
- Technical specifications name specific brands, standards, materials, or technologies without a clear technical reason, and equivalent alternatives are restricted.
- Qualification and experience requirements are higher than necessary for the contract, limiting the number of capable bidders.
- Specifications are changed after contact with suppliers, without a clear written reason or formal approval.
- Tender documents include data, drawings, or performance requirements that closely match the products or materials of one supplier.
Stakeholder Guidance
Stakeholder Exposure
Exposure includes pressure to follow brand or bidder specific requirement; higher bid costs; and reputational exposure if favoritism and restrictive specifications are identified.
Decision Point
Before bid/no‑bid decision, request technical clarification on the tender and design specifications, documenting the reasoning provided by the authorities.
Mitigation Actions
• Maintain an auditable record of technical inputs, meetings, and the rationale for decisions to bid or not bid, when technical or design specifications appear biased
• Use internal compliance escalation processes and whistleblower channels, where available, to flag cases in which bidding proposals are repeatedly prepared in response to tailored specific supplier or technology specification
• Request that authorities publish a clear justification for restrictive technical and design specifications, when this information is not publicly available
• Use formal administrative mechanisms to challenge restrictive technical and design specifications
• Avoid participating in bids where specifications are unlawfully restrictive, undisclosed, or designed to pre-select a vendor (including through late changes in specifications)
Mitigation Resources
Require conflict-of-interest declarations and documented conflict management for staff, advisers, and technical contributors involved in specification drafting or design decisions; exclude conflicted parties from the decision process until conflicts are resolved and documented.
Conflict-of-interest management and ethics controls — https://toolbox.infrastructuretransparency.org/resource/conflict-of-interest-management-and-ethics-controls/Review publicly disclosed design and tender records, including specifications, qualification requirements, lotting decisions, and late design changes; identify restrictive requirements, missing functional justification, absent equivalency language, or unexplained revisions early.
Transparency and data disclosure standards — https://toolbox.infrastructuretransparency.org/resource/transparency-and-data-disclosure-standards/Failure Cases
Good Practices
Stakeholder Exposure
Exposure includes inflated capex and O&M; increased performance risk due to restrictive bidding conditions; higher challenge and delay risk during the tender process; and reputational risk from perceived bid manipulation.
Decision Point
At design-readiness/procurement gateway, verify if technical and design specifications restrict competition.
Mitigation Actions
• Assess whether technical and design requirements unduly restrict competition or limit equivalency
• Condition engagement on the disclosure of specifications, evaluation criteria, and supporting rationale, including timely notice and justification of any material change
• Trigger an independent technical and procurement review when specifications or late changes appear to favour a single supplier without documented need or supporting evidence
• Pause approvals, commitments, or funding until findings are adequately addressed and documented
Mitigation Resources
Condition approval on a documented procurement approach, disclosure of specifications and evaluation criteria where lawful and available, and tender launch controls that challenge restrictive specifications, unjustified packaging, constrained equivalency, or late changes before tender launch.
Procurement governance and planning — https://toolbox.infrastructuretransparency.org/resource/procurement-governance-and-planning/Appoint an independent technical adviser to test whether key technical requirements, standards, packaging, and late design changes are justified, proportionate, and not tailored to a single supplier.
Independent technical due diligence and monitoring — https://toolbox.infrastructuretransparency.org/resource/independent-technical-due-diligence-and-monitoring/Failure Cases
Good Practices
Stakeholder Exposure
Exposure includes reduced competition and higher costs; lock-in to specific suppliers or technologies; increased risk of bid challenges and legal disputes; and loss of public trust in bidding outcomes.
Decision Point
Before approving final technical and design specifications, lotting/packaging, and qualification criteria, verify that competitive conditions are ensured.
Mitigation Actions
• Ensure that, where brands or standards are referenced in tender provisions, clear “or equivalent” criteria are included, together with justification for the restrictive provisions
• Adopt performance- or outcome-based requirements in tender specifications, where possible
• Publish draft specifications and qualification criteria for comment, where feasible, and record and respond to stakeholder inputs
• Maintain an auditable change log (what/why/who/when), with documented approvals, particularly for late specification changes
• Apply independent technical peer review to high-risk or potentially restrictive requirements
• Revise or remove constraints that lack evidence, proportionality, or a documented functional need
Mitigation Resources
Set the procurement approach, market-engagement rules, and tender launch controls for design and tender requirements; prevent restrictive specifications, unjustified packaging, constrained equivalency, and late design changes before tender launch.
Procurement governance and planning — https://toolbox.infrastructuretransparency.org/resource/procurement-governance-and-planning/Appoint an independent technical or procurement adviser to review the justification for restrictive design and tender requirements; require peer review before approving high-risk requirements that lack a documented functional need.
Independent technical due diligence and monitoring — https://toolbox.infrastructuretransparency.org/resource/independent-technical-due-diligence-and-monitoring/Publish and maintain public access to design and tender records, including draft specifications where lawful, qualification criteria, packaging decisions, change logs, and reasons for late or material changes, with only lawful redactions.
Transparency and data disclosure standards — https://toolbox.infrastructuretransparency.org/resource/transparency-and-data-disclosure-standards/Failure Cases
Good Practices
Stakeholder Exposure
Exposure includes reduced transparency and value-for-money in tender processes; higher costs, potentially affecting tariffs and service delivery; limited ability to challenge technical criteria; and risk of retaliation when raising concerns.
Decision Point
At the time of pipeline publication or, where this is not available, during site mobilisation, submit access to information to request technical and design specifications in order to verify that competitive conditions are maintained. Decide whether to (a) escalate through oversight channels to raise restrictive criteria and request justification, or (b) monitor while safely gathering evidence.
Mitigation Actions
• Identify and flag tender processes that rely on single-supplier provision, constrained equivalency provision, brand/proprietary references or disproportionate qualification criteria lacking functional justification
• Engage oversight bodies to report biased technical and design specifications (use safe, confidential reporting and anonymisation where retaliation risk is material)
Mitigation Resources
Screen published design and tender records, market-engagement records, and complaint signals for red flags such as brand references, single-supplier indicators, disproportionate qualification criteria, unjustified lotting, or late specification changes; file procurement complaints or oversight referrals where requirements favour a specific supplier without documented functional justification.
