Risk Assessment and Pre-Job Integration: Contractor shall perform documented risk assessments during planning and prior to execution, integrating Job Hazard Analyses/Job Safety Analyses (JHA/JSA), Human Performance (HU) tools, and applicable OE. Assessments shall identify critical steps, defenses, hold points, and verification methods. Pre-job briefs shall communicate the assessed risks and controls to all involved personnel.

C. Critical Evolution Gates

Before initiating any critical evolution (including but not limited to high-hazard lifts, confined space entry, energized work, hot work, work at height, or evolutions designated by Energy Northwest), Contractor shall:

1. Conduct a joint risk review with the Technical Representative or designee.

2. Verify control implementation and readiness (procedures, permits, qualifications, tooling, staging, independent checks).

3. Confirm go/no-go decision points and stop-work criteria.

4. Obtain documented concurrence from Contractor’s on-site supervisor and the Technical Representative or designee prior to execution.

D. Governance and Joint Reviews

1. Cadence: Contractor shall hold weekly IRM working reviews and monthly leadership reviews with Energy Northwest to examine the risk register, emerging issues, trend data, and corrective-action effectiveness. Minutes and action logs shall be maintained and provided upon request.

2. Emergent Risk: Contractor shall promptly convene an ad-hoc joint review for any emergent risk that exceeds escalation thresholds or degrades safety margin.

E. Early-Warning Notifications and Escalation

1. Thresholds: Contractor shall immediately notify the Technical Representative or designee upon any of the following:

a. Residual risk transitions to High/Red after controls.

b. Mitigations become ineffective or unavailable for a Moderate/Amber or High/Red risk.

c. Precursors to HU events or near misses indicate increasing risk

(trend or leading indicators).

d. OE indicates an unrecognized hazard or degraded defense relevant to the Work.

2. Timeliness and Format: Notifications shall be made within one hour for conditions in E.1.a and E.1.b, and within 24 hours for conditions in E.1.c and E.1.d, using email to the Technical Representative or designee, accompanied by a brief risk statement, current controls, and proposed recovery actions.

3. Stop-Work. Contractor shall self-initiate stop-work when residual risk is

High/Red or when defenses are not reliable. Resume only after joint review and written concurrence by the Technical Representative or designee.

F. Risk Controls Implementation and Verification

1. Contractor shall implement risk controls as specified in procedures and work orders and shall verify control effectiveness using independent checks or peer reviews where appropriate. Deviations from planned controls require prior approval from Energy Northwest.

G. Metrics and Reporting

1. Contractor shall submit a monthly IRM summary that includes risk distribution (by category and severity), movements in residual risk, control effectiveness, leading indicators, HU metrics and event-free days, and corrective-action status. Contractor shall analyze trends and propose adjustments to controls and governance based on data.

H. Records and Audit

1. IRM records (plans, registers, assessments, reviews, notifications, minutes, and actions) are project quality records and shall be retained per Contract requirements. Energy Northwest, including Corporate/Independent Oversight, may review IRM records and observe IRM practices; Contractor shall support such access and timely resolution of identified gaps.

I. Interface with Appendix “A”

1. IRM establishes baseline expectations across all Work. Scope-specific hazards, hold points, and acceptance criteria shall be identified in the Statement of Work (Appendix A), and shall remain consistent with this clause.

J. Performance and Remedies

1. Failure to maintain approved IRM practices, thresholds, and reporting may affect payments, trigger corrective-action plans, or constitute a performance deficiency under the Contract. Energy Northwest may require additional controls or suspend work until risks are reduced to acceptable levels

C.7 HUMAN PERFORMANCE & EVENT-FREE OPERATIONS

Contractor shall utilize site-standard HU tools (pre-job briefs, peer checks, procedure use and adherence, error-prevention techniques) and shall report HU indicators monthly, including event-free days, event significance, trends, and corrective-action status.

Contractor shall promptly analyze and correct negative trends and share lessons learned with Energy Northwest. Data shall align to recognized industry criteria for HU event significance to ensure consistency of reporting.

C.8 OPERATING EXPERIENCE

Contractor shall capture, analyze, and share relevant industry and site OE during performance of the Work. OE submissions shall include cause, conditions, defenses, learning points, and recommended changes to procedures or work instructions. Contractor shall integrate approved OE into the Work and brief affected personnel, down to the lowest level appropriate, prior to execution.

C.9 INDEPENDENT OVERSIGHT ACCESS

Energy Northwest personnel shall have reasonable access to observe Contractor work as an independent oversight, review relevant documents and data, and provide observations.

Contractor shall support such access and promptly address identified performance gaps.

This access reinforces self-awareness and continuous improvement and does not modify Contract scope or authority.

C.10 SUBCONTRACTOR FLOW-DOWN

Contractor shall flow down to critical Subcontractors the expectations for leadership behaviors, IRM, technical challenge, HU, and OE sharing described in Appendix “C” and the approved Supplier Performance & Partnership Plan. Contractor shall verify Subcontractor implementation through oversight and metrics and shall provide such evidence upon request.

C.11 WORKMANSHIP AND MATERIALS

A. Unless otherwise directed by the Technical Representative or designee or expressly provided for by the specifications issued under this Contract:

1. All workmanship shall be free of defects and faults.

2. All materials, equipment and supplies incorporated in the work are to be:

a. New and of the most suitable grade of their respective kinds for the purpose.

b. In accordance with any applicable drawings and specifications where materials, equipment and supplies are referred to in the specifications as “equal to” and particular standard, the Technical Representative or designee shall decide the question of equality.
