Summary

RLF can substantially reduce:

• Explanation load
• Micro-correction load
• Minor exception load
• Continuous inspection load
• Interrupt frequency
• Workflow drift
• Peer discipline enforcement

RLF cannot eliminate:

• Hold-point authority
• High-risk task supervision
• Legal safety responsibility
• Structural deviation approval
• Major exception resolution
• Final QC acceptance

Structural Implication

If RLF certification is rigorous and enforced:

• Class A tasks can operate at very high student:instructor ratios
• Class B tasks can operate at moderate-high ratios
• Class C tasks remain instructor-constrained

Overall achievable ratio depends on:

• % of time spent in each work regime
• Interrupt frequency
• Exception density
• Enforcement discipline

A/B/C Task Risk Classification Matrix

Class	Risk Profile	Injury Hazard Level	Structural / System Consequence	Reversibility of Error	Required QC Method	Instructor Presence Requirement	Typical Examples
A	Low Risk / Modular / Reversible	Low	Minimal downstream impact	Easily correctable with low cost/time	Traveler + Peer Signoff + Statistical Audit	Periodic / On-Demand	Insulation install, trim carpentry, cabinet assembly, prefab blocking, drywall (non-structural), labeling, staging, panel assembly on jigs
B	Moderate Risk / Structural Interface	Moderate	Impacts structure, envelope, or downstream trades	Correctable before irreversible step, but costly if missed	Traveler + Photo Documentation + Instructor Hold-Point Gate	Scheduled Gate Inspection	Framing layout, window install, roof decking, air barrier install, rough plumbing, rough electrical (non-panel), HVAC routing, sheathing, structural ties
C	High Risk / Irreversible / Hazardous	High	Structural failure, major liability, or safety exposure	Difficult or impossible to reverse without major rework	Mandatory Instructor Signoff + Direct Supervision	Continuous During Task Execution	Foundation prep before pour, beam placement, crane/lift operation, electrical panel termination, live circuit testing, roof truss placement, concrete pour coordination, structural shear inspection

Classification Rule

A task is assigned to the highest class triggered by any of the following:

• Injury hazard potential
• Structural consequence of failure
• Irreversibility or high rework cost

Ratio Implications

Class	Ratio Feasibility	Conditions Required
A	High (1:15–1:30+ possible)	Strong RLF certification, jigs, traveler enforcement, low interrupt rate
B	Moderate (1:8–1:15 typical)	Defined hold points, photo documentation, disciplined sequencing
C	Low (1:4–1:8 typical)	Direct instructor supervision, formal authority, safety enforcement

Strategic Implication

RLF objective:

• Convert as many B tasks into A through engineering controls.
• Minimize time spent in C through certification and hazard reduction.
• Strictly gate C tasks to prevent ratio collapse.
