If there's one area of the 2024 EM 385-1-1 revision that has created the most immediate, operational impact for contractors, it's training. The new manual completely restructured the training requirements that govern who needs to be trained, on what content, for how long, and how often.
For safety managers trying to keep their teams compliant, understanding the new training tiers isn't just helpful — it's required.
The 2014 edition of EM 385-1-1 had training requirements that were often described as unclear or inconsistently applied. Different districts interpreted the requirements differently, resulting in situations where a contractor qualified for work in one USACE district couldn't demonstrate equivalent qualification in another.
The 2024 revision standardizes training tiers across the board, tying specific training durations to specific roles and responsibilities. The result is a four-tier training framework built around the amount and depth of EM 385-1-1 knowledge required for each role on a USACE project.
The 40-hour training course is the most comprehensive offering and covers the entirety of the 2024 EM 385-1-1 manual. This training is designed for:
If you are the designated SSHO on a USACE project, the 40-hour course is the baseline. It's important to note that this training must be based on the 2024 edition — training completed under the 2014 curriculum does not satisfy 2024 requirements.
The 40-hour course covers all 37 chapters of the revised manual, including the new chapters on Rope Access, Uncrewed Aircraft, and Emergency Operations, plus the updated CE-SOHMS framework, the new APP requirements, and the revised AHA and activity planning requirements.
The 24-hour training course targets contractors, military and government personnel, and CDSOs. It provides coverage of the EM 385-1-1 requirements relevant to the roles of these personnel and satisfies a portion of the 24-hour refresher training that CDSOs are required to complete every four years.
This is the training tier that affects the broadest number of people working on USACE projects. If you're a contractor (but not the SSHO), a government employee involved in construction management, or a CDSO maintaining your qualification, the 24-hour course is likely your required level.
The 16-hour course provides an overview of the EM 385-1-1 manual and serves as an introductory qualification for personnel who need a foundational understanding of USACE safety requirements. This is appropriate for supervisors, foremen, or support personnel whose roles involve some safety responsibility but not the comprehensive oversight function of an SSHO.
For field supervisors who are responsible for daily pre-task planning and crew safety management, a genuine grounding in the manual's requirements is the difference between effective safety leadership and just passing out hard hats.
SSHOs are required to maintain their qualifications through annual 8-hour refresher training, beginning one year after completing the initial 40-hour course. This refresher ensures that SSHOs stay current as the manual evolves and as USACE guidance is updated.
The 8-hour refresher can be obtained from any qualified training provider — there is no requirement to use the same provider as the original 40-hour course. This flexibility allows companies to find training that fits their schedule, budget, and delivery format.
For contractors whose teams were trained under the 2014 manual, the transition question is straightforward but uncomfortable: that training does not satisfy the 2024 requirements. The 2024 edition is not a revision of the 2014 content — it's a substantially rewritten document with new chapters, new requirements, and a new organizational structure.
Companies need to schedule retraining for their designated SSHOs and CDSOs. Build retraining into your contract startup checklist as a mandatory pre-mobilization requirement.
Under the 2024 manual, documentation of training is not optional. Contractors are expected to maintain records including the training provider, course duration, completion date, and the edition of the manual covered.
Best practice: maintain a training matrix for every USACE project that shows each person's name, role, required training tier, completion date, and refresher due date. This matrix should be available for review at the pre-construction safety conference and during any QAR inspection.
Build a training compliance calendar for your USACE safety team that tracks initial qualifications, annual refresher due dates, and CDSO four-year renewal cycles.
