  1. 1.Preliminary model estimation and2.Actual Model costing Prepared by: Assoc. Prof. Sr Dr. Mastura Jaafar

  2. PART A:Preliminary model estimation 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

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

  5. Examples

  6. Examples

  7. Examples

  8. Costing estimations • Material • Labour • Equipment • Wastage • Profit

  9. BASIC ELEMENTS • Basic elements

  10. Cost Estimation • 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

  11. PART B: ACTUAL MODEL COSTING • 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.

  12. PART B: ACTUAL MODEL COSTING • 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.

  13. PART B: ACTUAL MODEL COSTING 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.CostDifferences in cost planning and actual estimation =RM 200.00 = 3-1

  14. PART C: ELEMENTARY ESTIMATION 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)

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