Unbilled Work & Change Order Omissions in BOQ-Based Billing
Definition
BOQ defines all billable work items and quantities[4]. However: (1) Site variations require formal change orders, which are often delayed in approval; (2) Work outside BOQ scope (mobilization, temporary facilities) may not be explicitly priced; (3) Contingency allowances in contracts may be overlooked; (4) Performance incentives or penalty deductions are manually tracked, prone to error; (5) Change orders issued verbally but not documented in time for certification.
Key Findings
- Financial Impact: 2–5% of contract value unbilled: AED 200,000–500,000 per AED 10M contract; delayed change order recovery = 30–60 days of additional AR aging; estimated loss on a AED 100M turnover = AED 2,000,000–5,000,000 annually
- Frequency: Per change order event; cumulative monthly/quarterly billing cycles
- Root Cause: BOQ is static; site variations require dynamic tracking. Manual change order workflow (verbal instruction → documented request → engineer approval → cost agreement → invoice) is slow. No automated linkage between site work orders, BOQ updates, and billing system.
