Construction Safety Advisor

We are seeking an experienced Construction Safety Advisor to support our construction teams by ensuring compliance with CDM regulations, maintaining high standards of on-site safety, and contributing to Human & Organisational Performance (HOP) initiatives. You will be a key partner to project and design teams, bridging the gap between regulatory frameworks and practical site execution.

What you’ll be doing as the Construction Safety Advisor

Lead compliance with CDM 2015: support design teams, coordinate pre-construction info, check contractor competence, and handle notifications.
Conduct design-phase reviews and regular site inspections to identify hazards and apply effective controls.
Develop and enforce site-specific HSE policies, permit-to-work systems, and toolbox talk frameworks.
Facilitate HOP-informed workshops (e.g., “work-as-done” reviews, learning teams, after-action reviews) to shift safety culture from blame to system-focused learning.
Partner with project teams to integrate safety into planning, ensuring systems anticipate human error and support frontline adaptability.
Plan and deliver safety briefings, inductions, and multi-disciplinary forums, inspired by HOP principles.
Investigate incidents and near-misses with root-cause analysis grounded in HOP philosophies—viewing individuals as problem-solvers, not problems.
Maintain rigorous safety records—audit reports, risk assessments, inspection logs—aligned with CDM and UK safety standards.

Base location:
Reading – with travel required
Working pattern: 36 Hours
