CCA CCA Construction Fraud Detection and Prevention 1 — Questions and Answers
Question 1: Which of the following billing schemes is most commonly identified by CCA auditors on construction projects?
- Overbilling for work not yet performed or billing for work never completed (Correct answer)
- Underbilling to defer income recognition to the following fiscal year
- Billing for work performed by a competitor on a different project
- Billing for materials at below-market prices to benefit the owner
Correct answer: Overbilling for work not yet performed or billing for work never completed
Front-loading and billing for incomplete or non-existent work is the most prevalent billing fraud on construction projects, exploiting the difficulty of verifying work completion in the field.
Question 2: What is bid rigging in construction procurement, and how does an auditor typically detect it?
- Collusion among bidders to predetermine the winner, detected by statistical analysis of bid amounts and patterns (Correct answer)
- A contractor submitting artificially low bids to win work then recovering costs through change orders
- An owner steering contracts to preferred contractors through biased specifications
- A subcontractor submitting bids to multiple GCs for the same project at different prices
Correct answer: Collusion among bidders to predetermine the winner, detected by statistical analysis of bid amounts and patterns
Bid rigging involves competitors coordinating bids so that a designated winner submits the lowest price, detectable through statistical anomalies like identical bid amounts, complementary bidding patterns, and bid rotation.
Question 3: A construction auditor reviewing payroll records finds that 15 workers have the same home address listed on their W-4 forms. This is most consistent with:
- Ghost employee payroll fraud using a single address to collect multiple paychecks (Correct answer)
- A legitimate crew housing arrangement at a remote project site
- A payroll processing error that duplicated the address field
- Workers sharing a company dormitory during the project
Correct answer: Ghost employee payroll fraud using a single address to collect multiple paychecks
Multiple employees sharing an identical address on payroll records is a classic indicator of ghost employee fraud, where fictitious workers are added to payroll to divert funds.
Question 4: Which audit technique is most effective for detecting materials overbilling on a construction cost-plus project?
- Tracing vendor invoices to actual delivery tickets and performing a physical inventory of materials on site (Correct answer)
- Reviewing the contractor's purchasing department organization chart
- Confirming material suppliers' trade references provided by the contractor
- Reviewing the contractor's accounts payable aging report
Correct answer: Tracing vendor invoices to actual delivery tickets and performing a physical inventory of materials on site
Comparing billed quantities on vendor invoices to delivery tickets and conducting a physical inventory reconciliation exposes overbilling of materials never delivered or already used on other projects.
Question 5: A contractor on a cost-plus project includes depreciation on contractor-owned equipment in the billing to the owner. How should the CCA auditor treat this charge?
- Disallow depreciation and verify that only the contractually allowable equipment use rate is charged (Correct answer)
- Allow depreciation as it represents the actual cost of using the equipment
- Allow depreciation only if the equipment was purchased specifically for this project
- Convert the depreciation to a rental rate and allow at 150% of book depreciation
Correct answer: Disallow depreciation and verify that only the contractually allowable equipment use rate is charged
Cost-plus contracts typically specify allowable equipment rates; double-charging by billing both depreciation and an equipment use rate is impermissible.
Question 6: Which behavioral red flag in a construction project manager most commonly precedes discovery of contract fraud?
- Refusing to take vacation, insisting on personally handling all payments and approvals without oversight (Correct answer)
- Submitting detailed expense reports with receipts for all project-related costs
- Requesting an independent audit of the project's financial records
- Reporting potential vendor conflicts of interest to the compliance officer
Correct answer: Refusing to take vacation, insisting on personally handling all payments and approvals without oversight
Refusal to take vacations and insistence on sole control over financial processes are classic fraud indicators because perpetrators fear that a substitute will discover the scheme in their absence.
