22. mass of wasted materials is calculated using the project specification and applying component wastage rates i e the percentage of the component that will be wasted For example if the wastage rate for bricks is 20 then for every 100 of bricks bought it is assumed that 20 will be wasted if this 100 of bricks has a weight of 500kg then it is assumed that 100kg will be wasted By taking this bottom up approach to waste estimation the wastes forecasted for a project are specific to both the type and quantity of the components used This is important because the major sources of waste on one project e g bricks may be completely absent in another e g if cladding panels are used rather than bricks The Tool contains information on the typical levels of construction wastage for each of the components in the database Data is held on both the baseline levels of wastage and a lower wastage level that could be achieved by adopting good practices for waste reduction Using the brick example above if the baseline wastage rate is 20 and the wastage rate after good practices have Material change for a better environment Niet Waste Tool 71 been adopted is 10 then the potential saving in materials value and mass is 10 and 50kg respectively By forecasting the value and mass of wasted materials for all of the components on a project the Tool can identify the most significant sources of waste i e those where the adoption of

24. selected components are too low this would result in the Tool predicting that not all of the construction cost has been accounted for because it has underestimated the cost of some elements For the RC element of the Tool a high above 20 percentage of unaccounted value will simply result in a conservative estimate of the total recycled content of the project because unaccounted value is assumed to contain no recycled content However for the waste module lots of unaccounted value should be avoided on a project because this may mean that the forecast levels of waste arisings and disposal costs will be inaccurate potentially resulting in inappropriate project decisions 1 have an unusually shaped building how do I use the Tool The simple estimates of project quantities determined using building dimensions are unlikely to be accurate where a building has unusual design features e g irregular floorplates or mezzanine levels In these cases the best way to use the Tool is to simply enter component quantities directly in for each component when using the Add Components screen based on the information in the project cost plan bill of quantities My project uses a Waste Broker If your project is using a waste broker that has provided a fixed price quote for managing all of the wastes on the project the Tool s default approach to estimating disposal cost based on the cost per skip is not applicable The most suitable way to enter th
