NZQA registered unit standard 26782 version 1 Page 1 of 4 Title Use measurements for infrastructure works purposes Level 3 Purpose Credits 6 This unit standard is for people working in the infrastructure works industry who are required to use and calculate measurements for infrastructure works purposes People credited with this unit standard are able to: identify and convert standard units of measurement; use area measurement; calculate and use volume and weight measurements; and use proportions for infrastructure works purposes. Classification Infrastructure Works > Generic Infrastructure Works Available grade Achieved Explanatory notes 1 Assessment against this unit standard requires evidence of the application of mathematics to practical infrastructure works activities. Assessment parameters will be dependent on sector, company and site specific equipment, procedures, and practices. 2 Evidence is required of calculating measurements using mathematics and showing working. 3 Definition Weight is used in this unit standard to refer to measurements in kilograms not Newtons. Outcomes and evidence requirements Outcome 1 Identify and convert standard units of measurement used for infrastructure works. Range two each of – length, area, volume, weight. Infrastructure ITO SSB Code 101813 New Zealand Qualifications Authority 2016 NZQA registered unit standard 26782 version 1 Page 2 of 4 Evidence requirements 1.1 Measurements used for infrastructure works activities, materials, and products, are identified. Range 1.2 may include – kerb line, road width, road marking dimensions, trench, stockpile, car park, measuring wheel, sign spacing, aggregate, chemical, water. Measurements are converted from one unit of measurement to another; relevant to infrastructure works activities, materials, and products. Outcome 2 Use area measurement for infrastructure works purposes. Evidence requirements 2.1 Using a plan, the area of an irregular shape is estimated to the accuracy of one square unit. 2.2 The area of a rectangular sports field or car park is calculated for an infrastructure activity accurate to two decimal places. Range activity may include – spraying, turfing, sealing. 2.3 The area of a triangular space is subtracted from a rectangular area for an infrastructure activity accurate to two decimal places. 2.4 The area of a parallelogram or trapezoid shaped surface is calculated and used to determine a coverage rate. Range 2.5 coverage may include – agrichemical, turf, vegetation, chipseal. Areas incorporating circular boundaries are calculated using geometry. Range area – a traffic roundabout, a part of a circle relevant to infrastructure works. Outcome 3 Calculate and use volume and weight measurements for infrastructure works purposes. Range may include the following methods – end areas, prisms, cross sections, estimating, standard geometrical shapes. Evidence requirements 3.1 The volume of a cylindrical tanker is calculated and used to estimate the number of loads required to fill or empty a storage tank of specified size. Infrastructure ITO SSB Code 101813 New Zealand Qualifications Authority 2016 NZQA registered unit standard 3.2 The volume of a heap is calculated and the number of loads to remove it is estimated for a given load size. Range 3.3 26782 version 1 Page 3 of 4 heaps may include – spill, stockpile; one with round base, one with rectangular base. The volume of material required for an infrastructure works activity is calculated to the nearest cubic unit. Range may include but is not limited to – agrichemical, earthwork cut and fill, compacted material, glass beads. 3.4 The weight of material required to fill a given area is calculated to determine the number of loads required to transport material to an infrastructure works site. 3.5 Weight of infrastructure works materials to the nearest unit is estimated from a given cubic measurement. Range 3.6 two materials. The filled weight of a container is estimated for three different infrastructure works materials. Range materials may include – aggregate, chemical powder, glass beads, water. Outcome 4 Use proportions for infrastructure works purposes. Evidence requirements 4.1 Ratios are used to determine the number of containers or loads of each component to supply a works site with materials for a specified mix. Range 4.2 Ratios are used to work out how much of a mixture has to be added to top up a partially filled container and calculate how much of each component is required to maintain the same mix. Range 4.3 mix has at least three components. mix has at least two components; components may include – agrichemical, additive, modifier, water, wetting agent. Percentages are calculated accurate to one decimal place for a decrease in relation to an infrastructure works activity. Range Infrastructure ITO SSB Code 101813 may include – crossfall, costs. New Zealand Qualifications Authority 2016 NZQA registered unit standard 4.4 26782 version 1 Page 4 of 4 Percentages are calculated accurate to two decimal places in relation to an infrastructure works activity. may include – active ingredient, compaction, concrete mix. Range Planned review date 31 December 2015 Status information and last date for assessment for superseded versions Process Version Date Last Date for Assessment Registration 1 18 March 2011 N/A Accreditation and Moderation Action Plan (AMAP) reference 0101 This AMAP can be accessed at http://www.nzqa.govt.nz/framework/search/index.do. Please note Providers must be granted consent to assess against standards (accredited) by NZQA, 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. 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. Consent 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.
