1. 1.Preliminary model estimation and 2.Actual Model costing Prepared by: Assoc. Prof. Sr Dr. Mastura Jaafar Prepared by: Assoc. Prof. Sr Dr. Mastura Jaafar

2. Is a cost estimation/planning for developing your model. Objective: To enable the design team to determine how much is needed for developing a model PART A:Preliminary model estimation

3. 1.Taking Off-To know the quantity of material, type of material and unit used. 2. Need to know the price of material-Where to get the price? Supplier Internet-CIDB website/JKR Contractor/consultant

4. Model drawing and its specification-roof plan/floor plan/elevations. Information from the drawing:- Type and size of material Connection Finishes-paint How to get the quantity of the materials?

5. Examples

6. Examples

7. Examples

8. Taking off sheet Waqf Column 4” X 4” Concrete roofing tiles Timber 1” X 1” (300’ length) 4 100 20 Nos Pcs Nos

9. Material Labour Equipment Wastage Profit Costing estimations

10. Basic elements ElementsElement of Quantity MaterialPlywood, roofing material, nails, batten 1” X 2” etc LabourRM50.00/days/8 hours Wastage% according to the type of material Profit10% from the overall model cost EquipmentSaw, hammer, cutter, electric drill, (Based on actual market price)

11. Quantity of material X price (RM) =material price (M) Wastage (…..% from M)= W Labor= how many hours X how many people X rate/hour (RM) =L Equipment (buying)=E Profit (10% from {M+L+W+E} =P Total cost estimation = M+L+W+E+P Cost Estimation

12. To assess whether a balanced distribution of costs have been achieved amongst the various elements of the model. To provide comparison of costs of the preliminary estimation and actual costing Actual cost estimation based on weekly estimation.

13. Students need to provide: 1. Preliminary model estimation- 2. Weekly model estimation-based on actual work done 3. Actual model costing=accumulative of weekly estimation with a report on costing comparison between 1 and 3. The actual model costing for the new project is ready.

14. 1. Preliminary model estimation = RM1,500.00 2. Weekly model estimation-based on actual work done (could be different from PME either +/-) Week 1 =RM500.00 Week 2=RM1,200.00 3. Actual model costing based on work done =Week 1+Week 2=RM1,700.00 4.Cost Differences in cost planning and actual estimation =RM 200.00 = 3-1

15. Objective: To propose estimation based each model elements. Task: Students need to provide estimation based on each model elements that are:- 1.Foundation/ground beam 2.Column 3.Floor 4.Wall 5.WallFinishes and 6.Column (The element list depending on each proposed model)

16. 1. Preliminary model estimation = 29 th Nov 2. Weekly model estimation=weekly report (together with other reports-A4)=29 th Nov and 9 th Dec 3. Actual model costing and Cost Differences = 9 th Dec 4.Elementary estimation = 9 th Dec.
