1 Page 1 of 5 Title Identify and inspect road safety barrier systems on Infrastructure Works sites Level 4 Credits 10 Purpose People credited with this unit standard are able to: identify and explain road safety barrier systems, performance, principles and design; assess the hazards and fitness of the road safety barrier systems to protect against identified hazards; carry out an inspection of an installed road safety barrier system to determine compliance; carry out an inspection of road safety barrier systems to determine maintenance requirements, including repair of crash damage. Classification Infrastructure Works > Generic Infrastructure Works Available grade Achieved Entry information Recommended skills and knowledge Unit 22993, Install guard rails or wire rope barriers on civil construction works; or demonstrate equivalent knowledge and skills. Explanatory notes 1 The following legislation and regulations must be complied with: Health and Safety in Employment Act 1992; Health and Safety in Employment Regulations 1995; and Civil Defence Emergency Management Act Assessment against this unit standard must take place in a roading environment. Assessment parameters will be dependent on Road Controlling Authority and site specific equipment, procedures, and practices. Practices must reflect industry best practice and comply with legislative requirements. 3 The following codes of practice and guidelines must be complied with: New Zealand Transport Agency (NZTA) NZTA M23 Specification for Road Safety Barrier Systems and associated appendices. A full listing of NZTA s resources and manuals and specification documents are listed on Any legislation or other requirements superseding any of the above will apply, pending the review of this unit standard.

Operational requirements are any legal requirements, standards, codes of practice, plans, organisational policies and procedures, and standard operating procedures (SOPs). Contract specifications include plans, diagrams, and special technical conditions associated with the road safety barrier systems installation. They do not include special administrative conditions. Manufacturer s instructions may include specifications, installation, handling, use and maintenance instructions specific to the road safety barrier systems. Road safety barrier systems are designed and engineered to absorb vehicle impact. 5 Inspection for gas, telecommunications and power services in the vicinity of the road safety barrier systems should be carried out under supervision of the relevant service provider. Outcomes and evidence requirements Outcome 1 Identify and explain road safety barrier systems. 1.1 Roadside and median barriers are identified and their function is explained. includes but not limited to proprietary and non-proprietary road safety barrier systems, end terminals, crash cushions and transitions. 1.2 Bridge barrier systems and associated transitions are identified and their function is explained in accordance with manufacturer s instructions. Outcome 2 Identify road safety barrier systems performance, principles and design in accordance with NZTA M23 Specification for Road Safety Barrier Systems. 2.1 Non-proprietary road safety barrier systems are identified. includes but not limited to semi-rigid roadside and median barriers, rigid roadside and median barriers, pre-cast concrete barriers in both permanent and temporary situations.

3 Page 3 of Proprietary road safety barrier systems are identified. includes but not limited to flexible barrier systems, semi-rigid systems in both permanent and temporary situations. 2.3 End terminals, crash cushions and transitions are identified. includes but not limited to flared and tangential layouts, post types, special requirements. Outcome 3 Assess the hazard and fitness of the road safety barrier systems to protect against identified hazards. 3.1 Road safety barrier systems location is checked to identify roadside hazards and ensure they are mitigated by the associated road safety barrier systems. includes but not limited to clear zone, shy line, gating clear area, run out length, length of need, road shoulder, verge, batter clearances, hazards, obstructions, underground services. 3.2 Hazards associated with the road safety barrier system itself are mitigated. includes but not limited to road safety barrier systems, warning signs, traffic flow. Outcome 4 Carry out an inspection of installed road safety barrier system to determine compliance. 4.1 Inspection of the road safety barrier system installation is conducted in accordance with the contract specification and manufacturer s instructions. includes but not limited to flexible barriers systems, semi-rigid systems, rigid systems, ground sockets for barrier posts, rail or wire rope connections, end terminals, crash cushions. 4.2 Inspection records of the road safety barrier system installation are completed in accordance with the contract specification and manufacturer s instructions. Outcome 5 Carry out an inspection of road safety barrier systems to determine maintenance requirements, including repair of crash damage.

4 Page 4 of Road safety barrier systems are inspected and type of maintenance work is identified in terms of maintenance period. includes but not limited to routine and collision maintenance, and repair of crash damage. 5.2 Maintenance inspection records for the road safety barrier systems are maintained in accordance with the contract specification or asset management plan. 5.3 Road safety barrier systems repair and maintenance records are reviewed and confirmed in accordance with contract specification and NZTA M23 Specification for Road Safety Barrier Systems. 5.4 Maintenance inspection records are sent to the site or contract engineer in accordance with operational requirements.

Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards. Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards. Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMR). The CMR also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
