Concrete and Formwork VR Training: Shoring, Impalement and Post-Tensioning (OSHA Subpart Q)
VR concrete scenario on OSHA 1926 Subpart Q: formwork drawings, shoring inspection before and during placement, rebar impalement protection, post-tensioning zones and pump hazards.
QUICK ANSWER
OSHA 1926.703 requires formwork designed to support all loads, drawings at the jobsite and shoring inspected before, during and after placement. 1926.701 requires guarding of protruding rebar and keeping workers out from behind jacks during post-tensioning. A VR scenario runs a crew through an elevated slab pour, from pre-pour walk to stressing day.
What the Rule Requires
29 CFR 1926.703, Cast-in-place concrete: formwork must be designed, fabricated, erected, supported, braced and maintained to support all vertical and lateral loads, drawings or plans for jack layout, formwork, shoring and scaffolding must be available at the jobsite, and shoring must be inspected before, during and immediately after concrete placement. Section 1926.701 covers rebar guarding, post-tensioning and limits on riding concrete buckets.
Formwork collapses usually happen during the pour, when the load is highest and the crew is standing on the deck. The scenario is a post-tensioned elevated slab on the fourth floor of a parking structure: reshores below, a pump boom overhead, column dowels sticking up at the edge and stressing jacks set up the next week.
Hazards in This Scenario
- Collapse of formwork or shoring under the wet concrete load
- Impalement on protruding rebar and column dowels
- Tendon or anchor failure behind the jack during post-tensioning
- Pump line whip and boom contact during placement
The Procedure the Scenario Rehearses
- Compare the shoring layout on site with the drawings and confirm the engineer sign-off
- Inspect shores, reshores, jacks and bracing before the pour
- Cap or cover every protruding bar at the edge and in the work area
- Watch for shore movement and deflection during placement and stop the pour if it starts
- Set the stressing exclusion zone and keep everyone out from behind the jack
- Strip forms only when the concrete strength and the engineer say so
Mistakes the Scenario Is Built to Catch
- Starting the pour before the shoring inspection is signed
- Leaving dowels uncapped next to the deck edge
- Standing behind the jack to watch the gauge during stressing
- Pulling reshores early to move them to the next floor
Competence Assessment Matrix
| Decision point | What the assessor sees | Pass standard |
|---|---|---|
| Drawings | Whether the layout on site is compared with the approved drawings | Differences found and reported before the pour |
| Shoring inspection | When and what the learner inspects | Checked before, during and immediately after placement |
| Rebar guarding | Protruding bars left exposed | Every impalement hazard capped or covered |
| Stressing zone | Where people stand during post-tensioning | No one behind the jack or in the exclusion zone |
What VR Covers
- A full elevated pour with shore movement shown as it develops
- Collapse and tendon failure consequences without anyone at risk
- Inspection practice on shoring with hidden defects
- A record of each check per worker and per pour
What VR Does Not Replace
- Engineering design of the formwork and shoring system
- Field inspection by the competent person on the real deck
- Hands-on form building, placing and finishing skills
Scope of a One-Scenario Pilot
A pilot builds this scenario as a single module, in Unity or Unreal Engine depending on the visual fidelity the task needs and the headsets on site. It runs on standalone headsets, logs every learner decision, and exports a per-person record for your training file. It is measured against your current method with a test cohort before anything is scaled.
Frequently Asked Questions
When must shoring be inspected?
Before, during and immediately after concrete placement, under 1926.703(b)(2).
Must rebar be capped?
All protruding reinforcing steel onto which employees could fall must be guarded to eliminate the hazard of impalement, under 1926.701(b).
Can VR replace engineering review of formwork?
No. VR trains the crew to recognize problems. The formwork design and approval stay with the engineer.
