2 Overview Introduction Project acceleration terminology  Normal Time, normal cost  Crash Time, crash cost  Direct Costs  Indirect Costs  Total Project Cost  Optimum Project Duration Project acceleration principles References Introduction Project acceleration terminology  Normal Time, normal cost  Crash Time, crash cost  Direct Costs  Indirect Costs  Total Project Cost  Optimum Project Duration Project acceleration principles References

3 „When I know all information, only can make a right decisions.” Paulo Coelho Introduction

4 Steps of right decision:  Definiate: Time and costs  Analysed the possibilities  Compare the opportunities  Choose the best way Steps of right decision:  Definiate: Time and costs  Analysed the possibilities  Compare the opportunities  Choose the best way Introduction

5 Project acceleration terminology Normal Time, normal cost This is the usual time that would be needed to carry out the electrical services work under normal circumstances, estimated at 12 days with a cost of £10.000.

6 Project acceleration terminology Crash Time, crash cost The crash time is the maximum time the operation can be compressed by increasing the resources. Crash time: 8 days Crash cost: £18.000

7 Project acceleration terminology Cost Slope

8 Project acceleration terminology Activity ranking Analysed the precedence relationship Identified the critical activities Ranking by the cost Reduce the duration Define the critical path

9 Project acceleration terminology Direct costs: Labour Plants Materials Subcontractors Overheads and profit

10 Project acceleration terminology Indirect costs: Project supervision Site hutting and accomodation Site office telephones, heating and lighting Vans and site transport

11 Project acceleration terminology Direct costs + Indirect costs Total cost

12 Optimum project duration

13 Project acceleration principles Example – based on a network arrow diagram

Direct costs =£198 000 + £23 000 =£221 000 Indirect costs =23 weeks x £2 000 =£46 000 Total Project Cost £267 000 Therefore, in order to achieve an acceleration of 5 weeks, the project cost will be increased by £13 000, that is: Crash Cost =£267 000 Less Normal Cost =£254 000 Acceleration Cost =£13 000 Reduction in project period
