Phase 6: Operation & Maintenance

Inflated O&M costs, kickbacks and overcharging

Operating costs, spare parts, and service charges are inflated through overpricing, unnecessary works, and kickbacks, undermining service quality and project financial sustainability.

Red Flags & Indicators

  • Parts and consumables are priced consistently above benchmarks, with repeated sole-source awards or split purchases used to bypass approval thresholds.
  • Maintenance callouts are unusually frequent, duplicative, or poorly justified.
  • Non-routine works are approved without clear need or asset-condition evidence
  • Invoices and work orders lack delivery notes, service logs, and sign-offs
  • Billed quantities and items do not reconcile with inventory issued and parts installed.
  • The same suppliers are repeatedly favoured, with unclear commissions, discounts or rebate arrangements.
  • Decision-making and approval authority are concentrated among a limited group of individuals.

Stakeholder Guidance

Stakeholder Exposure

Exposure includes overpriced parts and unnecessary maintenance; higher risk of reduced margins and cash leakage through kickbacks; pressure to approve suspect invoices and suppliers; increased risk of disputes, audits, and potential debarment; and reputational risk.

Decision Point

Before approving O&M invoices and spare parts purchases, verify supporting rates, work orders, and inventory logs.

Mitigation Actions

• Adopt and apply an O&M plan, documenting deviations from the plan
• Validate O&M charges against contract rates and benchmark pricing for parts and consumables
• Document reasoning for splitting purchases
• Document any sole-source justification
• Require complete evidence for each invoice and work order (delivery note, job card, asset ID, time logs, supervisor sign-off)
• Reconcile billed items to inventory issuance and installation records
• Apply supplier and subcontractor integrity controls (competitive sourcing where feasible, segregation of roles, traceable payments, no commissions linked to approvals)
• Apply conflict-of-interest and related-party checks for suppliers and subcontractors
• Use internal compliance escalation processes and whistleblower channels, where available, to report pressure to approve unjustified works or inflated invoices
• Pause payments when red flags persist
