Government construction represents one of the largest and most stable markets for contractors. Federal, state, and local agencies spend over $300 billion annually on construction—and these contracts offer reliable payment, long-term relationships, and predictable work pipelines.

Why Government Contracting?

Government contracts offer unique advantages: payment is virtually guaranteed, contracts are awarded based on merit, and small businesses often get preferential access through set-aside programs. The key is understanding the system.

Advantages of Government Work
  • Payment security: Government agencies pay—it may take time, but payment is virtually guaranteed
  • Fair competition: Transparent procurement based on published criteria
  • Small business programs: Set-asides and preferences for qualified small businesses
  • Predictable pipeline: Capital improvement plans show future projects
  • Relationship building: Performance on one project opens doors to more

Best For:

  • - Complex projects
  • - Design-build contracts
  • - Projects requiring specialized expertise

Key Points:

  • - Qualifications and approach matter
  • - May involve interviews
  • - Negotiation possible
Set-Aside Contracts

Contracts reserved for specific categories of contractors. Reduces competition and helps targeted businesses grow.

Federal Set-Asides:

  • - Small Business (SB)
  • - 8(a) Business Development
  • - HUBZone
  • - SDVOSB (Service-Disabled Veteran)
  • - WOSB (Women-Owned)

Getting Registered

Before bidding government work, you need proper registration. Requirements vary by agency level.

Federal Registration Requirements
  1. 1
    DUNS/UEI Number

    Unique Entity Identifier required for all federal contractors. Free to obtain through SAM.gov.

  2. 2
    SAM.gov Registration

    System for Award Management—mandatory for all federal contracts. Free registration, renewed annually.

  3. 3
    NAICS Codes

    Select construction codes that match your capabilities (236xxx for building, 237xxx for heavy/civil).

  4. 4
    Small Business Certifications

    If eligible, apply for 8(a), HUBZone, SDVOSB, WOSB, or other programs through SBA.

State & Local Registration
  • State vendor registration: Each state has a vendor portal (e.g., BidSync, PublicPurchase, state-specific)
  • Contractor licensing: State license in proper classification for project type
  • DBE/MBE/WBE certification: Through state DOT or certifying agency
  • Prequalification: Some states require prequalification for larger projects

Registration Takes Time

SAM.gov registration can take 2-4 weeks. SBA certifications can take months. Start the registration process well before you need to bid—you can't bid without active registrations.

Compliance Requirements

Government contracts come with compliance requirements beyond private work. Understanding these upfront prevents costly surprises.

Prevailing Wage (Davis-Bacon)

Federal projects over $2,000 require paying locally prevailing wages for each trade. State projects have similar requirements.

  • Must pay wage determination rates
  • Submit certified payroll reports
  • Post wage determination on site
  • Violations result in debarment risk
Bonding Requirements

Federal projects over $150,000 require bid, performance, and payment bonds under the Miller Act.

  • Bid bond: 5-20% of bid amount
  • Performance bond: 100% of contract value
  • Payment bond: 100% of contract value
  • State/local may have different thresholds
Additional Compliance Requirements
  • Buy American/Build America: Requirements to use domestic materials and products
  • DBE/MBE participation: Meeting subcontracting goals for disadvantaged businesses
  • Equal Employment Opportunity: Non-discrimination and affirmative action requirements
  • E-Verify: Employment eligibility verification (federal and many states)
  • Safety reporting: OSHA compliance and incident reporting

Strategies for Winning Government Contracts

Winning Strategies
  • Start small: Build past performance with smaller contracts before pursuing large projects
  • Get certified: Small business certifications dramatically reduce competition
  • Subcontract first: Build relationships and experience as a subcontractor before bidding prime
  • Attend industry days: Meet contracting officers and learn about upcoming projects
  • Focus on responsiveness: Submit complete, compliant bids—non-responsiveness disqualifies many bidders
  • Build relationships: Government contracting is about long-term relationships, not one-time wins

Common Mistakes to Avoid

  • - Bidding projects beyond your experience level
  • - Missing required forms or certifications
  • - Underestimating prevailing wage costs
  • - Not acknowledging addenda
  • - Submitting after the deadline (late = rejected)

Frequently Asked Questions

How do I get started with government contracting?

Start with SAM.gov registration, obtain necessary licenses and insurance, build bonding capacity, and begin bidding smaller projects. Consider subcontracting to prime contractors to build past performance before bidding prime contracts.

Do I need to be the lowest bidder to win?

For sealed bid (IFB) contracts, yes—lowest responsive, responsible bidder wins. For RFPs (best value), price is one factor among many including qualifications and approach. Small business set-asides may also evaluate factors beyond price.

What certifications should I pursue?

Depends on your eligibility. Small business certification is easiest. If you qualify, pursue 8(a), HUBZone, SDVOSB, or WOSB for federal set-asides. For state/local work, get DBE certification through your state DOT.

How long does government payment take?

Federal prompt payment rules require payment within 30 days of proper invoice. In practice, 30-45 days is common. State and local can vary. Plan cash flow accordingly and use payment bonds to protect yourself on prime contracts.

Conclusion

Government construction offers tremendous opportunity for contractors willing to learn the system. While compliance requirements add complexity, the benefits—reliable payment, fair competition, and preferential access for small businesses—make it worthwhile.

Start with proper registration, build experience through subcontracting or smaller projects, pursue relevant certifications, and develop long-term relationships with government agencies in your area.
