New Zealand Qualifications Authority 2016 1020 version 5 Page 2 of 4 Elements and performance criteria Element 1 Identify water requirements from a given landscape plan. Performance criteria 1.1 The delivery system of water available for the watering system is identified in terms of the characteristics of the source. Range 1.2 pressure, volume, pumping requirements. Water requirements for individual elements of the soft landscape plan are identified. Range lawns, annuals, perennials, bulbs, trees, shrubs. 1.3 Total application requirements for the site are calculated from individual element requirements. 1.4 Water application rates are determined with regard to plant requirements and prevention of soil problems. Range 1.5 effects on soil – structural and textural modification, nutrient leaching, toxic residues, ponding, run-off, erosion. Water delivery rates are identified in terms of the effects of pipe diameter, length, and type, and water pressure. Element 2 Define the requirements of an irrigation system to meet identified site needs. Performance criteria 2.1 Pumping or storage modifications from the water source required to provide the volume and pressure to meet calculated application needs are identified, and the methods of achieving these modifications are defined. Range 2.2 capacity, type, installation requirements. The method of application is selected and justified for each element of the soft landscape to enable water to be applied to meet the correct watering requirement. Range micro irrigation, in-ground sprinkler, above-ground sprinkler. New Zealand Qualifications Authority 2016 1020 version 5 Page 3 of 4 2.3 Distribution elements for the system are described and selected from information supplied by manufacturers to design a system that will provide the required application rates for the landscape site. Range pipe work – size and type, control systems, application element size and type. Element 3 Install an irrigation system to achieve application rates required. Performance criteria 3.1 Material and/or system element needs are taken from plans or specifications and are ordered using detailing methods which define type, size, and quantity required. Range pump, control equipment, application units, fittings, fixing or support requirements, pipe. 3.2 All elements of the system are installed in accordance with manufacturer's requirements and workplace procedures. 3.3 Tools and equipment are selected from a given range and used in accordance with workplace procedures to achieve a specified outcome, without damage to system elements, injury to the operator, or danger to others. Range at least eight of – pipe wrench, water boiler, crox tools, pipe vice, PVC pipe clip applicator, hacksaw, adjustable spanner, adhesives, pipe threader, pipe bender, PVC pipe cutters, adjustable pliers. 3.4 Electrical connections to the system are made by an approved installer, to the standard required for certification by the relevant authority. 3.5 Completed watering system is trialled, and adjustments are made to achieve required coverage and application rates. 3.6 Watering system elements are protected from damage by weather, traffic, or other work in accordance with workplace procedures. 3.7 Surplus material is removed, and site is left in a condition which enables further work to be undertaken unimpeded in accordance with workplace procedures. 3.8 A maintenance programme which ensures that the system continues to operate to maximum efficiency is developed and presented to the client. Please note Providers must be accredited by the Qualifications Authority, or an inter-institutional body with delegated authority for quality assurance, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment. New Zealand Qualifications Authority 2016 1020 version 5 Page 4 of 4 Industry Training Organisations must be accredited by the Qualifications Authority before they can register credits from assessment against unit standards. Accredited providers and Industry Training Organisations assessing against unit standards must engage with the moderation system that applies to those standards. Accreditation requirements and an outline of the moderation system that applies to this standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The AMAP 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.
