WJEC Vocational Award Constructing the Built Environment Level 1/2

KEY TERM Quantification: The end product of a process to conclude the gross (before wages, tax and other expenditure) and net (after paying tax) sum of a particular task or a group of tasks. LINK For more on tolerances see pages 82 and 153. AC2.2 Calculate materials required to complete construction tasks When you want to effectively prepare materials, you should have the skills to be able to calculate the amounts required to successfully achieve the task. When materials are procured, regardless of type, they will be available in regulated and definitive weights and/or measures to ensure that they are consistently manufactured and distributed. You also need to be aware of the limitations of the materials in terms of their working time (wet materials require time to dry) and the ratios in which they need to be blended with other materials/elements. SKILLS Time and cost The time and cost of the total process needs to be accurately calculated to ensure sustainable levels of production can be planned and achieved. Their final weight, size, density and appearance are often part of the standards to which the materials are processed and/or manufactured to. These same standards are consistently checked by manufacturers, designers, builders and those responsible for checking quality in the industry such as construction managers, Engineers, Architects and all specialist contractors. These checking procedures are governed by strict tolerances that are often published as institutional standards and/or approved codes of practice. These are the same standards that are often referred to within specifications, drawings, building regulations and design briefs. This process of quantification is also an appreciation of the time it takes to successfully procure, distribute, prepare and use the materials. So, the process is dependent on efficient programming to ensure the series of events from the point or ordering them to the point of arrival on site, to the time when they form part of the completed works, is accurately appreciated. There are six elemental calculations to help you comprehend the full resources that will be required to complete a construction task: 1 Area 4 Time 2 Volume 5 Ratio 3 Perimeter 6 Costs 68 Unit 2 Developing Construction Projects
