Introduction

Winning a government construction bid is just the first step. Financing the project—covering labor, materials, equipment, and overhead before payment arrives—is often the greater challenge. Many capable contractors lose opportunities because they lack the financial capacity to execute.

Government construction creates unique financing challenges. Retainage holds back 5-10% of each payment. Payment cycles often run 30-45 days. Prevailing wage requirements increase labor costs. And bonding requirements tie up financial capacity.

This guide explores financing options available to construction contractors pursuing government work, helping you build the financial capacity to bid on and execute larger projects.

Construction Financing Challenges

  • Front-loaded costs: Pay for labor/materials before getting paid
  • Retainage: 5-10% withheld until project completion
  • Payment delays: 30-45+ day payment cycles
  • Bonding requirements: Ties up financial capacity
  • Seasonal workloads: Uneven cash flow throughout year

Understanding Financing Needs

Before pursuing financing, assess your specific needs for the projects you're targeting.

Cash Flow Analysis

Project your cash needs by considering:

  • Mobilization costs before first payment
  • Ongoing labor and material costs
  • Payment timing from owner
  • Subcontractor payment obligations
  • Retainage accumulation
  • Overhead during project

  • Track record: Successful project completions
  • Management: Experience and depth

Frequently Asked Questions

How much working capital do I need for government work?

A general guideline is 10-15% of annual revenue in working capital. For a specific project, plan for 2-3 months of project costs as float between expenses and payments. Factor in retainage accumulation over the project lifecycle.

Can I get bonding with poor personal credit?

It's challenging but not impossible. Sureties look at business financials, experience, and personal credit. Strong business performance can offset personal credit issues. Consider the SBA Surety Bond Guarantee Program for additional support.

Is invoice factoring worth the cost?

It depends on your situation. If factoring enables you to take on profitable work you couldn't otherwise fund, the cost may be worthwhile. Calculate the effective annual rate and compare to your project margins. For ongoing needs, a line of credit is usually more cost-effective.

How do I find construction-friendly lenders?

Look for lenders experienced in construction: local banks with construction portfolios, specialty construction lenders, and SBA-approved lenders familiar with contractor needs. Industry associations often have lender relationships.

Conclusion

Adequate financing is essential for success in government construction. Build your financial capacity proactively—don't wait until you win a project that exceeds your resources.

Develop relationships with lenders and sureties before you need them. Maintain strong financial practices that support growth. And match your bid strategy to your financial capacity, gradually expanding as you build resources.
