Construction Noise: A Pervasive Occupational Hazard

Construction is Australia’s second-highest-risk industry for NIHL after mining. Yet construction presents unique compliance challenges: workers are mobile across multiple project sites, employment is often contract-based, and multiple contractors operate simultaneously on single projects.

Noise Sources in Construction

• Pneumatic drills: 100-110 dB (percussion drilling, rock breaking)
• Concrete saws and cutters: 105 dB sustained
• Nail guns: 97-100 dB impulse; repeated exposures throughout shift
• Angle grinders and disc saws: 95-100 dB
• Compressors and generators: 85-95 dB continuous
• Multiple concurrent sources: On active construction sites, multiple tools operate simultaneously, creating cumulative exposure of 90-105 dB(A)

The Construction Challenge: Mobile Workforce, Multiple Sites

Unlike mining with concentrated FIFO workforces, construction workers are highly mobile. A carpenter might work for multiple contractors across different projects throughout a year. Managing audiometric testing for this dispersed workforce requires careful coordination.

Principal Contractor vs. Subcontractor Responsibilities

Principal contractor: The main contractor managing the overall project has primary WHS responsibility. This includes establishing the framework for hearing health monitoring across all personnel on-site.

Subcontractors: Specialized contractors (structural, mechanical, electrical, etc.) are responsible for their own workers’ hearing health but must integrate with the principal contractor’s testing program.

Key Construction Regions

Major construction boom regions requiring coordinated hearing testing include: Western Sydney (residential and infrastructure boom), South East Queensland (Brisbane, Gold Coast development), and Melbourne northern suburbs (industrial and residential expansion).

Managing Testing Across Projects

For principal contractors overseeing multiple concurrent projects, coordinate annual audiometric testing program that spans all on-site personnel. For subcontractors with rotating project assignments, maintain baseline audiograms and track 2-year monitoring requirements across workers’ employment history.

Conclusion: Coordination for Compliance

Construction hearing health requires coordinated effort between principal contractors and subcontractors. Establish clear testing protocols, maintain comprehensive records across project transitions, and ensure all noise-exposed workers participate in annual monitoring.
