Quantifying resilience potentials in construction: pilot evaluation of the resilience assessment grid

Area of Science:

• Occupational Health and Safety Management (OHSM)
• Construction Safety
• Resilience Engineering

Background:

• Construction industry faces persistent hazards and accidents, necessitating a shift from Safety-I to resilience-centered OHSM.
• Traditional safety models are often rigid and checklist-driven, failing to capture dynamic risk management needs.

Purpose of the Study:

• To develop and validate a questionnaire for assessing resilience capabilities in the construction sector.
• To integrate resilience assessment into the Occupational Health and Safety Plan (OHSP).

Main Methods:

• A 36-item questionnaire was developed based on the Resilience Assessment Grid (RAG).
• Content validity was established using the Individual Aggregate Method, followed by expert consensus via a Delphi panel.
• Pilot implementation on a construction site assessed reliability (Cronbach's α = 0.914) and user acceptability.

Main Results:

• The questionnaire demonstrated robust psychometric properties and operational viability.
• Resilience performance showed a provisional "sometimes" alignment with the four RAG pillars: Respond, Monitor, Learn, and Anticipate.
• Data visualization using spider diagrams identified specific areas for resilience enhancement.

Conclusions:

• The RAG-based questionnaire provides an actionable framework for embedding adaptive capacities into OHSPs.
• It facilitates a transition from reactive safety practices to a proactive, foresight-driven Safety-II approach in construction.
• This tool empowers stakeholders to advance OHSM by enhancing construction site resilience.
