SPECIALIZED AUDIT SERVICES

Vendor & Contractor Auditing for Construction Projects

Vendor and contractor audits help organizations determine whether vendors, contractors, and subcontractors are performing and billing in accordance with their contractual obligations.

My audit services focus on reviewing project costs, contract compliance, billing documentation, field activities, and supporting records to identify discrepancies, overcharges, overpayments, and areas of financial risk.

Invoice & Cost Review

Review invoices against contracted rates, quantities, pricing, and supporting documentation.

Contract Compliance

Evaluate compliance with contract terms, conditions, pricing, schedules, change orders, and other requirements.

Field & Documentation Review

Verify labor, equipment, materials, LEMs, field tickets, inventories, and project activities.
