How to Avoid Construction Fraud: Scams to Watch Out for and Smart Prevention Strategies

The global construction industry which is worth over $13 trillion (!) is a powerhouse of economic activity. But with its sheer size, complexity, and fragmented networks of stakeholders, it’s also a massive target for fraud. According to a Harvard Business Review analysis, systemic issues like misaligned incentives, lack of transparency, inconsistent enforcement of regulations, and uneven access to information create the ideal conditions for fraud and corruption to thrive in the industry.

The Association of Certified Fraud Examiners (ACFE) has flagged a sharp rise in construction fraud schemes, where criminals pose as contractors, subcontractors, or suppliers to collect payments for work or goods that are never delivered. The Kroll Global Fraud Report (2015) revealed that 75% of construction, engineering, and infrastructure companies had experienced a fraud incident in the past year alone.

So, how do construction firms protect themselves in this high-risk environment? It starts with awareness. Let’s explore the most common construction fraud schemes and how to protect your business with reliable vendor verification tools like Venzer.

1. Business Email Compromise (BEC) Scams in Construction

Business Email Compromise (BEC) scams involve cybercriminals who impersonate trusted contacts like vendors or company executives via email. The goal is to trick financial staff into wiring funds to fraudulent accounts. These attacks often involve phishing, spoofed domains, or even hacked email inboxes.

Real Case: The Texas BEC Scheme

From November 2016 to July 2018, cybercriminals infiltrated a vendor's email system connected to a Houston-based construction firm. After months of monitoring email threads between the vendor and the construction company, the hackers sent a convincing fake email that appeared to come from the vendor, requesting a change in payment details. This single maneuver helped them attempt to steal over $3 million from government agencies, contractors, and a Houston-area college.

Prevention Tips

    Always confirm any banking changes with a known contact using a verified phone number.

    Implement multi-factor authentication (MFA) on all company email accounts.

    Educate staff on how to spot suspicious email requests and check URLs carefully.

2. Jobsite Theft and Material Diversion

Each year, roughly 13,000 cases of construction theft are reported across the U.S. Thieves target job sites and supply depots for high-value items like copper wiring, lumber, generators, and specialty tools. Some criminals go further by posing as subcontractors and charging supplies to another company's account, using forged IDs or documentation to pick them up.

Common Techniques

    Fake ID badges and uniforms to blend in with real crew members

    Night-time site access when security is reduced

    Fraudulent purchase orders used to collect materials meant for others

Prevention Tips

    Use security cameras and fencing at all construction sites.

    Cross-reference all pickups with
      verified work orders.
    verified work orders.

    Tag and track all high-value assets using RFID or GPS tracking systems.

3. Fake Supplier Scams

This increasingly common scam involves fraudsters setting up fake supplier accounts or impersonating legitimate vendors to bill for materials or services that never arrive. These “suppliers” often offer competitive pricing, forged certifications, and fake reviews to look credible.

Prevention Tips

    Verify suppliers through trusted third-party platforms such as
      Venzer
    Venzer

    Never rely solely on documents provided by the vendor; independent verification is essential.

    Require references and check them personally.

4. Billing and Invoice Fraud in Construction Projects

Billing fraud schemes exploit gaps in financial oversight and include:

    Charging for work that wasn’t performed

    Submitting fake invoices from shell companies

    Misusing company accounts for personal expenses

    Billing project tools or services used for private gain

    Assigning personal errands to subcontractors and expensing them to the client

These activities might seem small at first but can snowball into substantial financial loss, especially on large projects with dozens of subcontractors and suppliers.

Prevention Tips

    Employ three-way invoice matching (invoice, purchase order, and delivery confirmation).

    Separate teams for approval and payment processing.

    Conduct random audits and use financial software to flag anomalies.

5. Vendor Verification: Using Venzer in Preventing Construction Fraud

One of the most effective ways to prevent fraud is to verify the legitimacy of your vendors before you engage with them. This is where Venzer becomes a game-changer.

Why Is Vendor Verification Important?

Construction firms rely on numerous vendors and equipment rental companies. But without proper vetting, you risk doing business with fraudulent or unreliable companies. The Venzer verification process increases trust by ensuring the vendors you work with are legitimate, qualified, and reputable.

What Venzer Verifies

Venzer’s vendor verification process confirms critical aspects of a vendor’s business, including:

    Business Registration – Verifies that the company is a legally registered entity through each state’s Secretary of State website.

    Complaints – Reviews public complaints filed with consumer protection agencies.

    3rd Party Reviews – Gathers real feedback from past clients (homeowners, architects, contractors).

    Certifications – Checks for relevant trade licenses and industry credentials.

    Warranty Plan – Confirms whether the vendor offers a structured guarantee for their work.

    Credit Review – Evaluates the vendor’s financial health to assess risk and reliability.

How the Verification Process Works

A vendor joins the Venzer platform and starts receiving customer reviews. Venzer Analysts collect legal documents and registration certificates to verify the company’s status. Business legitimacy is confirmed through Secretary of State records and supplemental legal certificates.

The vendor’s information is re-verified every 3 months via a combination of:

    Automated email campaigns

    Direct analyst review

    Customer feedback and outreach

This recurring validation process ensures that the data stays up-to-date and reliable, reducing the risk of fraud for clients who rely on Venzer-verified vendors.

Why You Should Work with Verified Vendors

    Engaging verified vendors lowers your project risk by:

    Improving transparency and accountability

    Reducing the chances of impersonation or identity fraud

    Ensuring regulatory compliance

    Encouraging high-quality work backed by valid credentials

6. Building a Fraud-Resistant Construction Business

Fraud can derail even the best-managed projects. But prevention is possible when companies commit to a layered defense strategy that includes digital security, physical safeguards, financial oversight, and vendor verification.

Actionable Tips for Your Team

    Implement a vendor onboarding checklist with third-party verification tools like

    Educate employees and subcontractors on common scam tactics.

    Invest in audit-ready project management software to track spend, invoices, and changes.

Construction fraud can result in project delays, financial loss, legal trouble, and reputational damage. As criminals grow more sophisticated, the industry must keep pace with proactive fraud prevention methods. The best defense is a mix of education, technology, and trusted verification platforms like Venzer. By prioritizing due diligence, robust security protocols, and verified partnerships, you can stay focused on what really matters: delivering successful projects on time, on budget, and without surprises.
