1. Know the codes

  • NAICS 561612, Security Guards and Patrol Services, covers most guard contracts. Check your size against the SBA size standard for that code before bidding a set-aside.

  • Find open jobs on our security and guard contracts list, updated daily.

2. Read the performance work statement for these things

  1. Posts and hours: each post, its hours and days, and whether it's armed or unarmed. A 24/7 post is 8,760 hours a year.
  2. Guard qualifications: state guard licenses, firearms qualifications, background checks, training hours, CPR and first aid. Some agencies add their own certification, and for Federal Protective Service buildings guards are called Protective Security Officers (PSOs) and need agency training.
  3. Uniforms and equipment: who provides radios, vehicles, weapons and ammunition.
  4. Supervision and reporting: site supervisor, project manager, logs and incident reports.
  5. Start-up time: how quickly guards must be trained, cleared and posted after award. This drives your hiring costs.

3. Price from the Service Contract Act wage determination

Guard contracts are covered by the Service Contract Act. The wage determination attached to the solicitation lists minimum hourly rates for job titles such as Guard I (unarmed) and Guard II (typically armed, with more responsibility). On top of the wage you must provide the health and welfare amount per hour, plus the paid vacation and holidays it lists. If the incumbent's guards are unionized, a collective bargaining agreement may set higher wages for you as the successor.

4. Worked example: one 24/7 unarmed post

The numbers below are illustrative only. Use your solicitation's wage determination and your real costs.

Hours to cover8,760 per year (24 hours × 365 days)
Wage + H&WExample: $20.00 Guard I wage + $5.00 health and welfare = $25.00
Vacation, holidays, training timeExample: 10% of wage = $2.00
Payroll taxes, workers' comp, liability insuranceExample: 15% of wages paid = $3.30
Uniforms, equipment, licensing, supervision shareExample: $1.70 per hour
Cost per post-hour$32.00
Overhead and profitExample: 12% = $3.84
Price per post-hourAbout $35.84, so about $313,960 a year for the post

Remember the relief factor: covering one 24/7 post takes roughly 4.2 to 4.8 full-time guards once you count days off, vacation, sick leave and training. Make sure your staffing plan and payroll budget reflect it.

5. The technical part (if evaluated)

  • Staffing plan: how you'll recruit, clear and train guards in time, and cover call-outs.
  • Quality control: post inspections, supervisor checks and how fast you fix problems.
  • Past performance: commercial, state or local guard contracts count (no federal experience yet?).

Common mistakes

  1. Pricing below the wage determination or forgetting health and welfare.
  2. Forgetting the relief factor, overtime exposure or holiday premiums.
  3. Underestimating start-up: clearances and training can take weeks.
  4. Missing an option year or surge-hours line item.
  5. Not holding the state licenses the work requires.
