Hazards & Risks Covered

Hazard Risk Description
1. Governance, WHS Duties and Resourcing
  • • Inadequate understanding by officers and senior management of primary duties under WHS Act 2011 and associated Regulations
  • • Insufficient resourcing (time, budget, competent people, plant) to plan and manage pipe and culvert works safely
  • • Lack of clear WHS objectives, KPIs and accountability for project leaders and supervisors
  • • Poor integration of WHS requirements into project governance, contracts and program milestones
  • • Failure to consult, cooperate and coordinate activities with principal contractors, subcontractors and utilities
2. Design, Engineering and Constructability Management
  • • Design not eliminating or minimising risks so far as is reasonably practicable (SFAIRP), contrary to WHS Act 2011 and WHS Regulations (designer duties)
  • • Insufficient geotechnical, hydrological and structural assessment leading to unsuitable trench designs, culvert sizing and support systems
  • • Lack of coordination between permanent works design and temporary works design (shoring, batter slopes, dewatering systems, lifting configurations)
  • • Inadequate consideration of constructability leading to excessive manual handling, complex lifts or unsafe sequencing with mobile plant and traffic
  • • Failure to consider whole-of-life maintenance and inspection access for pipes and culverts, creating long-term confined space and access hazards
3. WHS Risk Management and Planning Systems
  • • Inconsistent or informal risk assessments that do not consider systemic risks associated with excavation, services, mobile plant, traffic and environmental conditions
  • • Failure to update risk assessments when project scope, methods, design or site conditions change
  • • Over-reliance on generic risk assessments and SWMS that do not address specific site hazards (e.g. ground instability, nearby roads, flooding)
  • • Lack of integration of risk controls into construction schedules, method statements and resource plans
4. Procurement and Contractor Management
  • • Engagement of subcontractors and suppliers without adequate assessment of their WHS competence and past performance
  • • Procurement processes that prioritise lowest cost over safe methods, adequate supervision and compliant equipment
  • • Inconsistent WHS expectations and standards across different contractors on the same project
  • • Supply of pipes, culverts, lifting accessories and shoring equipment without appropriate certifications, ratings or instructions
5. Competency, Licensing and Training Systems
  • • Workers, supervisors and plant operators lacking formal competencies or licences for high-risk plant and activities associated with trenching and pipe laying
  • • Inadequate training in site-specific hazards such as ground instability, underground services, confined spaces and traffic interfaces
  • • Supervisors not adequately trained in WHS leadership, risk assessment, permit systems and emergency procedures
  • • Poor induction processes leading to inconsistent understanding of procedures and expectations
6. Documentation, Procedures and SWMS Management
  • • Absence of clear written procedures for key risk areas such as excavation, working near services, lifting and confined space entry
  • • Outdated or conflicting procedures, standards and SWMS across different projects and contractors
  • • Workers and supervisors not accessing or understanding current versions of procedures and SWMS
  • • SWMS being treated as a paperwork exercise without meaningful worker consultation or practical application
7. Plant, Equipment and Maintenance Systems
  • • Use of unsuitable or poorly maintained plant for excavation, lifting and handling of pipes and culverts
  • • Lack of systematic inspection and maintenance programs for excavators, cranes, lifting gear, trench shields and shoring
  • • No formal process to assess and control risks of new or hired plant, including guarding, stability and emergency systems
  • • Inadequate systems for isolating defective plant and communicating restrictions to workers
8. Services, Utilities and Asset Protection Management
  • • Unidentified or poorly mapped underground services leading to strikes during excavation
