Application

This unit of competency specifies the skills and knowledge required to conduct a survey of waterproofing systems and remedial recommendations for buildings.
The unit applies to Class 1 and 10 Buildings, and Class 2 to 9 Buildings.
The unit covers planning and preparing to conduct a survey of waterproofing systems, carrying out the survey of waterproofing systems, analysing report findings and making recommendations, and evaluating and communicating survey findings.
The unit is suitable for builders, building supervisors, building surveyors, building designers, architects, waterproofing design specialists, waterproofing supervisors, and consultants, engineers or other design specialists.
Licensing, legislative, regulatory or certification requirements may apply to this unit. Relevant work health and safety (WHS) state and territory regulatory authorities should be consulted to confirm jurisdictional requirements.

Assessment Requirements

Performance Evidence

A person demonstrating competency in this unit must satisfy the requirements of the elements, performance criteria and foundation skills of this unit, in addition to the specific performance and knowledge evidence described below.
The candidate must develop one (1) survey report for each of the below:
• an internal wet area
• an external above ground area
• a below ground system
• a remedial waterproofing system.
The survey report must include a stage inspection or hold point report and final inspection report.
The candidate must also provide a review of documentation or specifications for each waterproofing system above.
One (1) or more of the survey reports must identify a latent condition and must include recommendations for a resolution of the latent condition.
The survey reports must include:
• parameters of survey in accordance with stakeholders’ brief
• classification of wet areas
• assessment of waterproofing design against compliance with National Construction Code (NCC) performance requirements, Australian Standards, building design and use of area
• site conditions at the time of survey
• provision of stage inspection protocols and benchmarks for compliance with design and manufacturers’ specifications
• methodical collation of observations from survey
• review of observations against compliance of design and manufacturers’ specifications
• recommendations for remediation of defects and confirming compliant installation practices
• identify latent conditions outside of systems design
• recommendations to remediate the latent conditions to assist with the remediation advice
• provision of remedial scope and timeframe for remedial works to completion in accordance with survey report
• review of survey findings and recommendations against waterproofing design.

Assessment Conditions

Assessors must meet the requirements for assessors contained in the Standards for Registered Training Organisations.
Assessment of performance must be undertaken in the workplace or simulated workplace environment. A simulated workplace is one that fully replicates the resources, environment and any time and productivity pressures that exist in the actual workplace, and which meets industry standards for safety and environmental practices.
Candidates must have access to:
• relevant tasks
• Australian Standards, relevant building legislation, industry codes, NCC and requirements of workplace policies and procedures as required by Commonwealth, state and territory regulators
• relevant environmental requirements.
