EM 385-1-1 is the U.S. Army Corps of Engineers Safety and Health Requirements Manual — the safety document every USACE, NAVFAC, Air Force Civil Engineer Center, and federal-civil-works construction contract references as the governing safety standard. The credentialing structure sits at four hour tiers: 8-hour supervisor refresher, 16-hour supervisor introduction, 24-hour SSHO baseline, and 40-hour SSHO or lead-safety-professional baseline. Every hour tier matches a specific project size, role, and refresher requirement. Buying the wrong tier is one of the most expensive credentialing errors on a federal construction contract; it produces contract non-conformances, submitted-and-rejected SSHO qualification packages, and delayed mobilization.
This post is written for federal construction contractor owners, USACE SSHO candidates, DOD-project safety managers, and prime-contractor credentialing leads who need to match crew members to the correct EM 385-1-1 hour tier before the mobilization window opens. It walks through what each tier covers, which project size and role it fits, and why the 40-hour tier is the defensible baseline for the site safety and health officer (SSHO) function on any project of consequence.
Why The EM 385-1-1 Hour Tier Matters More Than The Course
The four hour tiers are not interchangeable. Each maps to a specific project size, role, and refresher cycle defined by USACE and the individual federal contract:
- 8-Hour Refresher. The renewal course for a supervisor or SSHO who has previously completed the 24-hour or 40-hour tier. USACE and most DOD contracting officers require the 8-hour refresher every 3 to 5 years, with the specific cycle set in the contract.
- 16-Hour Introduction. The introductory tier for supervisors on smaller USACE or DOD projects, typically construction contracts under $10 million with limited hazard scope. Not accepted as SSHO qualification on most tier-one contracts.
- 24-Hour SSHO Baseline. The minimum tier accepted as SSHO qualification on many USACE and NAVFAC contracts. The 24-hour tier is the practical baseline for smaller-project SSHOs and for supervisors who will not personally serve as the SSHO but need EM 385 fluency for site-supervisor roles.
- 40-Hour SSHO Baseline. The industry-recognized baseline for the SSHO function on any USACE contract of consequence. The 40-hour tier is required or preferred on the largest share of tier-one USACE, NAVFAC, and Air Force Civil Engineer Center scopes; it is the credential most SSHO qualification packages get built around.
USACE issued the current edition of EM 385-1-1 on November 30, 2014, with subsequent revisions and change notices. Contractors bidding new contracts should confirm the contract-specific edition and change-notice date in the solicitation package.
Why The 40-Hour Tier Is The Defensible Baseline
The 40-Hour EM 385-1-1 course is the credentialing tier the largest share of USACE and DOD prime-contractor SSHO qualification packages get built around. It is the baseline that lets the contractor submit a single qualification package across the widest range of USACE, NAVFAC, and Air Force Civil Engineer Center opportunities without having to re-credential the SSHO for each contract.
The 40-hour tier applies to any candidate serving in the SSHO role on a federal construction contract of consequence.
- USACE prime-contractor SSHO on a $50M+ contract: 40-Hour EM 385-1-1 is the required baseline; supplement with OSHA 30 Construction ($189) and the standard-specific competent-person credentials (Fall Protection, Confined Space, Excavation) called out in the contract.
- NAVFAC subcontractor SSHO on a facilities-support contract: 40-Hour EM 385-1-1 is the safe baseline; confirm the specific contract SSHO qualification clause, which some NAVFAC contracts write to a 24-hour minimum with prior-experience preference.
- Transitioning service member entering federal safety consulting: 40-Hour EM 385-1-1 is the credential most federal-contractor employers will screen for on the resume; it is the single credential that opens the largest share of SSHO-track and federal-safety-consultant roles.
Default rule: any candidate serving or preparing to serve in the SSHO role on a federal construction contract of consequence should hold the 40-Hour EM 385-1-1 credential rather than the 24-hour or 16-hour tier.
Price: $395 (360training). Fully online, USACE-recognized. Most candidates complete the 40-hour course in 8–12 sessions across 3–6 weeks.
When The 24-Hour Tier Is The Right Fit
The 24-Hour EM 385-1-1 course is the appropriate baseline for supervisors and smaller-project SSHOs whose scope does not require the full 40-hour credential. The 24-hour tier is a materially lower-cost credential ($285) and closes the SSHO qualification requirement on many smaller USACE and DOD contracts.
The 24-hour tier is the right path when:
- The candidate is serving as a site supervisor rather than the SSHO of record, and the contract requires EM 385 fluency but does not require the 40-hour credential.
- The candidate is the SSHO on a USACE or DOD contract with a written 24-hour minimum qualification clause and no prior-experience prerequisite for the 40-hour tier.
- The candidate holds prior USACE construction experience and is credentialing for a specific smaller-project SSHO role that accepts the 24-hour tier.
Caveat: the 24-hour tier is not accepted as SSHO qualification on most tier-one USACE prime-contractor scopes. A candidate serving as SSHO on a $50M+ USACE contract should credential to the 40-hour tier from the start rather than credentialing at 24 hours and upgrading later.
Price: $285 (360training). Fully online. Most candidates complete the 24-hour course in 5–8 sessions across 2–3 weeks.
Renewal And Currency Across The Hour Tiers
EM 385-1-1 credentials do not carry a federal expiration date, but USACE and DOD contracting officers set contract-specific refresher requirements that determine currency:
- Credential 1–3 years old: Confirmed current for most USACE, NAVFAC, and DOD contracts. Confirm the specific contract’s SSHO qualification clause for refresher requirements before submission.
- Credential 3–5 years old: Refresher training via the 8-hour course is the industry standard. USACE typically requires 8-hour refresher documentation every 3–5 years depending on the district and contract; most tier-one prime contractors require documented refresher at the 3-year mark.
- Credential 5+ years old, no refresher on file: Re-enrollment at the 24- or 40-hour tier is the defensible baseline. A SSHO submitted on a 5+ year credential with no refresher documentation is exposed on the qualification-package review.
Price: $185 for the 8-Hour EM 385-1-1 Refresher; $285 for 24-hour re-enrollment; $395 for 40-hour re-enrollment.
The Adjacent Credential Stack For Federal Construction
EM 385-1-1 is the federal safety standard, but the SSHO qualification package on any USACE or DOD contract also requires the underlying OSHA Outreach baseline and the standard-specific competent-person credentials called out in the contract:
| Need | Required item | Price |
| SSHO baseline for federal construction contracts of consequence | EM 385-1-1 40-Hour (360training) | $395 |
| Supervisor and smaller-SSHO baseline for federal construction | EM 385-1-1 24-Hour (360training) | $285 |
| Refresher for candidates with prior 24- or 40-hour credential | EM 385-1-1 8-Hour Refresher (360training) | $185 |
| Supervisor OSHA Outreach baseline (required alongside EM 385) | OSHA 30-Hour Construction (360training) | $189 |
| Fall protection competent person for federal contracts with fall hazards | Fall Protection Competent Person (360training) | $89 |
| Confined space supervisor for federal contracts with permit-required spaces | Confined Space Construction (Supervisors) (360training) | $189 |
Legally required vs. recommended: The EM 385-1-1 credential at the correct hour tier is the standard-specific requirement written into most USACE, NAVFAC, and Air Force Civil Engineer Center contracts. OSHA 30 Construction is the parallel civilian-construction credential most federal contracts also require. The competent-person credentials are contract-specific and vary by scope; the SSHO qualification package should be built to the specific contract requirements.
The Recommended Sequence For A Federal Construction Credentialing Plan
Federal construction contractors reading this post are typically credentialing candidates against active bids or upcoming mobilization windows. The following sequence is the most common defensible path:
Sequence:
- Confirm the SSHO qualification clause in the specific contract. USACE, NAVFAC, and Air Force Civil Engineer Center contracts have different SSHO qualification language; the hour-tier requirement is set in the contract, not by USACE broadly.
- Map the candidate to the correct EM 385 hour tier. SSHOs on contracts of consequence go to the 40-hour tier; smaller-project SSHOs and site supervisors go to the 24-hour tier; candidates with a prior 24- or 40-hour credential and a documented refresher cycle go to the 8-hour refresher.
- Confirm the OSHA 30 Construction credential is current. The OSHA Outreach card is required alongside EM 385 on most federal contracts; re-enroll any supervisor or SSHO whose card is over 5 years old.
- Layer the competent-person credentials called out in the contract. Fall Protection Competent Person is the most common competent-person credential on USACE contracts; Confined Space, Excavation, and Scaffolding follow depending on scope.
- Build the SSHO qualification package to the specific contract. The qualification package typically requires the EM 385 certificate, the OSHA 30 card, competent-person credentials, prior experience documentation, and resume/references.
- Document every credential in the corporate compliance file before submission. USACE, NAVFAC, and Air Force Civil Engineer Center contracting officers request the qualification package before mobilization; complete documentation on the first request is materially different from partial documentation.
Consequences Of The Wrong Hour Tier
- Immediate — rejected SSHO qualification package and delayed mobilization. A SSHO qualification package submitted at the wrong hour tier is rejected by the USACE, NAVFAC, or Air Force Civil Engineer Center contracting officer. Rejection triggers a re-credentialing cycle that typically adds 3–6 weeks to the mobilization schedule and can produce contract-liquidated-damages exposure on schedule-sensitive contracts.
- Regulatory — contract non-conformance and past-performance reporting. SSHO qualification failures are recorded in the Contractor Performance Assessment Reporting System (CPARS) and materially degrade the contractor’s past-performance rating on future federal bids. Repeat SSHO failures produce contractor debarment referrals.
- Long-term — competitive positioning on federal bids. Federal contract past-performance databases and prime-contractor qualification programs increasingly filter subcontractor bids on SSHO qualification history. A contractor without a consistent record of qualified SSHOs on completed contracts is materially disadvantaged on future federal opportunities.
The EM 385-1-1 40-Hour credential is the defensible SSHO baseline for federal construction contractors bidding tier-one USACE, NAVFAC, and Air Force Civil Engineer Center opportunities.

FAQ
1. What is EM 385-1-1?
EM 385-1-1 is the U.S. Army Corps of Engineers Safety and Health Requirements Manual — the safety document referenced as the governing safety standard on USACE, NAVFAC, Air Force Civil Engineer Center, and most federal-civil-works construction contracts. The current edition was issued November 30, 2014, with subsequent change notices; contractors should confirm the contract-specific edition and change-notice date in the solicitation package.
2. Which EM 385 hour tier does an SSHO need?
The SSHO hour tier is set in the specific contract, not by USACE broadly. The 40-Hour tier is the industry-recognized baseline for SSHOs on tier-one USACE contracts and is the credential most contractor qualification packages get built around. The 24-Hour tier is accepted on many smaller USACE and NAVFAC contracts. The 16-Hour tier is an introductory credential and is not typically accepted as SSHO qualification on tier-one contracts.
3. Does EM 385-1-1 replace the OSHA 30 Construction card?
No. EM 385-1-1 and OSHA 30 Construction are parallel credentials. Federal construction contracts typically require both: EM 385 as the federal safety-standard credential and OSHA 30 Construction as the civilian construction-safety Outreach card. Most SSHO qualification packages list both credentials.
4. How often does the EM 385 credential need to be refreshed?
USACE and DOD contracting officers set refresher requirements in the specific contract. Most tier-one contracts require 8-hour refresher documentation every 3–5 years for candidates who previously completed the 24- or 40-hour tier. A credential more than 5 years old with no refresher documentation is typically re-enrolled at the 24- or 40-hour tier.
5. Is the 40-Hour EM 385 course accepted by USACE, NAVFAC, and Air Force Civil Engineer Center?
The 360training 40-Hour EM 385-1-1 course is designed to meet USACE, NAVFAC, and Air Force Civil Engineer Center SSHO qualification requirements as written into most federal construction contracts. Contractors should confirm the specific contract’s SSHO qualification clause before enrollment to verify hour-tier and prior-experience requirements.
