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 PART A:Preliminary model estimation model 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

Model drawing and its specification-roof plan/floor plan/elevations.

Information from the drawing:-

Type and size of material

Connection

Finishes-paint

Costing estimations

Basic elements

Elements Element of Quantity

Material Plywood, roofing material, nails, batten 1” X 2” etc

Labour RM50.00/days/8 hours

Wastage % according to the type of material

Profit 10% from the overall model cost

Equipment Saw, hammer, cutter, electric drill, (Based on actual market price)

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

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.

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.

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

Objective: To propose estimation based each model elements.

Task: Students need to provide estimation based on each model elements that are:-1.Foundation/ground beam2.Column3.Floor4.Wall5.WallFinishes and 6.Column(The element list depending on each proposed model)

1. Preliminary model estimation = 29th Nov

2. Weekly model estimation=weekly report (together with other reports-A4)=29th Nov and 9th Dec

3. Actual model costing and Cost Differences = 9th Dec

4.Elementary estimation = 9th Dec.
