LA018091, Assessment 2, CPCCBA4004A, Ed 2_3_4 1 © New South Wales Technical and Further Education Commission, 2017 (TAFE NSW – WSI), Archive version 3, February 2017 CPCCBC4004A: Assessment 2 What you have to do Refer to project 1. When estimating, quantities are measured in different units often depending on how it is purchased. The common units of measure used are: m = metres m2 = square metres m3 = cubic metres No = number t = tonnes Item = an allowance of $ generally not involving a measured quantity and rate Note: Generally measure lengths areas & volumes to 2 decimal places, and roundup final quantities to next whole number. With weight measure and calculate to 2 decimal places but don’t roundup. For this assessment component you are required to take off quantities of materials from the plans detailing the cottage in Project 1. The quantities are to be recorded on P10 paper as shown below: Item Particulars Unit Quantity Rate $ C 1 90x45 F7 Radiata pine framing m 33 6/5.4 32.4 Note: you are describing, measuring and recording the quantities needed to complete the construction including wastage. This is also known by estimators as bill measure and extend. You do not have to price the quantities in this assessment. 2 LA018091, Assessment 2, CPCCBA4004A, Ed 2_3_4 © New South Wales Technical and Further Education Commission, 2017 (TAFE NSW – WSI), Archive version 3, February 2017 Task From the plans in Project 1, take off and extend the following quantities of materials/tasks: 1. Bored excavation for 300mm diameter piers. (Hint: measure in lineal metres and refer to structural detail. To determine piers number, locate one at every corner/beam intersection, then space between these at 1800 max.) 2. Bulk excavation to prepare site generally (but not the excavation for slab beams which is known as ‘detailed excavation’) Measure in m3 un-bulked. Allow to excavate 1m beyond the house walls for working space. Determine and state whether any excavated material will be required to be used as ‘fill’ and state the amount if fill needed. 3. N25 concrete to the slab on ground (beams, patio slab and pad footings; but excluding piers as these are typically bored and pored immediately after bulk earthworks) 4. SL72 reinforcing mesh to ground slabs. Measure the mesh twice: a) Nett measure in m2 – (when costed, the $ rate per m2 will include an amount for wastage) b) The number of sheets required to complete the slab. Note: reinforcing mesh is sold in 6.0m x 2.4m sheets. 2 bar overlaps are typically required resulting in an effective cover of 5.8m x 2.2m with 400mm lap. 5. The lengths of SL12TM required to complete the construction of the slab on ground. Note: trench mesh comes in 6m lengths. Measure in meters. 6. The structural steel in tonnes. Measure to 2 decimal places. 7. The plasterboard required to complete the lining of first floor rooms excluding the wet areas. Measure walls only. Measure the plasterboard twice: a) Nett measure in m2. The rate per m2 will include a wastage factor. b) The number of sheets of plasterboard required to complete the lining of the rooms. Sheet sizes vary – use 1200mm wide sheets x standard lengths, with a horizontal layout. 8. 66 x 18mm finished DAR primed pine skirting to the first floor rooms. (Hint: measure the skirting considering lengths available to purchase.) 9. Ceramic floor tiles to the following ground floor rooms: • Family room • Meals room • Kitchen – allow tile to go under the cupboards • Foyer/stair area (Hint: smaller tiles have a lower wastage factor than larger tiles. For this exercise allow 10% wastage on the nett floor area.)

CPCCBC4004A: Assessment 2 What you have to do Task Checklist LA018093 - Assessment 4, Unit code CPCCBC4004A, Edition number 2 & 3 1 © New South Wales Technical and Further Education Commission, 2014 (TAFE NSW – WSI), Archive version 1, June 2014 CPCCBC4004A – Assessment 4 What you have to do Refer to Project 1 on the OLS Task Part A (50 marks) From the site plan in Project 1, estimate the cost of a variation to provide the front fence as detailed on the plan. As the work is minor in extent, there is no need to measure in trade order but the tasks should be sequenced as they would occur in the construction process. Your builder’s bill should be prepared in P10 format. You can assume the site has been surveyed and identified with survey pegs to allow an easy set-out for the construction of the fence. Your builder’s bill should include the costing of the tasks identified and include a builder’s margin and GST. You should also nominate an appropriate ‘extension of time’ for the contract period to be extended if you believe it is warranted. When preparing your bill of quantities you can allow the following monetary sums: Face bricks $700.00 per thousand – supply and delivery. Sandstone capping $200.00 per metre (270 wide and 50mm thick) allow 20mm border (overhang) at each edge. Metal panels $100.00 per metre supply and delivery Helpful notes: Remove and tip all excavated material – you will need to make some assumptions for this task Provide adequate safety and security during the construction process Remove all rubbish on completion of the works Ignore all previous indicators of the cost of this exercise. They have not been correctly estimated, nor do they include the pricing information provided above. https://www.oten.edu.au/online/course/view.php?id=1160 2 LA018093 - Assessment 4, Unit code CPCCBC4004A, Edition number 2 & 3 © New South Wales Technical and Further Education Commission, 2014 (TAFE NSW – WSI), Archive version 1, June 2014 Part B (10 marks) Reflecting on your answer for Part A, please answer the following questions: 1. Explain the basis of your calculation of the labour component of installing the metal panels 2. As this is a variation, will all the labour components be priced at the same rate as the work in the main project which has been tendered on? Explain your answer. 3. Charge out rates for directly employed labour can be higher than sub-contract rates. Have you utilised any directly employed labour in your costing? If so, nominate the component and explain how you costed the rate. Note: at the very least there should be a cost for supervision of the work. 4. Is there any danger in the work associated with procuring and fixing the sandstone capping? Elaborate on your answer and explain how you will cover any risks identified. Part C (40 marks) 1. Briefly discuss the benefit of estimating the cost of a task by separately costing the materials, labour and plant required. 2. List the considerations that would affect your decision on whether to tender on a project or not. 3. When estimating the cost of excavation, what are the factors which determine the size of plant needed to complete the task? 4. What does the builder’s margin include? 5. Why do engineering drawings take precedence over architectural drawings when estimating and constructing a project? 6. Why are many components of the construction process sub-contracted out to other parties? 7. Discuss the issues with obtaining quotations from specialist trades or companies with whom you have no previous association and no direct knowledge of. 8. List the on-costs associated with directly employed labour. 9. List five (5) conditions of a contract which may produce a cost on the project and therefore should be included in your bill of quantities. 10. Discuss how you would calculate the labour cost to complete a task when you have no knowledge of the time involved to carry out the work.

CPCCBC4004A – Assessment 5 What you have to do Refer to • Project 1 on the OLS Task Part A (80 marks) For this assessment you are to complete a builder’s bill and estimate of the construction cost for the cottage detailed in Project #1. Before commencing this assessment, you need to successfully complete Assessments 1 to 4. Some of the work from these assessments can be used to complete this assignment. The builder’s bill must be prepared in trade order format and the following is a guide to the sections that should be included: • Preliminaries • Excavation • Concretor • Metalworker • Carpenter • Roofer • Wall board linings • Ceramic tiler • Painter • PC items • Provisional sums • Handover The following monetary sums are to be included in your estimate and are provided to lessen the amount of work you will need to complete. These sums would normally be valued by: • obtaining a quotation from a sub-contractor/supplier, or • estimating the cost yourself The amounts would then be included as prime cost items or provisional sums LA018094 Assessment 5 CPCCBC4004A Ed 2 & 3 1 © New South Wales Technical and Further Education Commission, 2014 (TAFE NSW – WSI), Archive version 2, May 2015 https://www.oten.edu.au/online/course/view.php?id=1160 Monetary Sums Prime cost items: 1.
