Sky Taxi Project Management: Detailed Analysis of Sky Taxi Project

This project management assignment analyzes the Sky Taxi Company's proposal to launch an aerial taxi service in Perth, Australia. The project encompasses the construction of docking stations, the use of electric VTOL crafts, and the implementation of solar panel networks. The assignment details the project's scope, including Gantt charts for electrical, mechanical, and communication/IT engineering, and an AOA diagram for electrical engineering to identify the critical path. The project also includes a complete master plan with timelines and a financial analysis to determine fare pricing and breakeven points, alongside a cash flow diagram. Furthermore, it compares two potential contractors, AAA and BBB, to determine the best fit for undertaking the project. The analysis provides insights into project scheduling, financial planning, and the selection of contractors for a complex, multi-faceted project.

SKY TAXI PROJECT MANAGEMENT 3
Introduction
The Sky Taxi Company proposed to offer an aerial-based taxi service in the locality of Perth
city. The company intend to use a total of 10 fully-electric VTOL crafts powered by network of
solar panels to supplement the main electricity grid. The Sky Taxi business is expected to be a
stand-alone project which is fully-costed and self-sustaining. This paper provides an engineering
consultancy guide to the Sky taxi’s project management. The project Gantt charts are first
outlined to show the project plan timelines. This is then followed by financial analysis to
determine the taxi pricing that will achieve a breakeven in 10 years of the project. Finally, two
potential companies are compared financially to choose the best company to undertake the
project (Trivoli, 2016).
Task List
Task 1: Gantt chart for Electrical, Mechanical and Communication/IT scope of work
The project start date for the Master plan is January 1, 2021, week 0. The electrical, mechanical
and Communication/IT engineering works start at the end of the completion of the construction
phase, that is, the whole Civil Engineering work scope must be completed prior to their start.
This happens at activity J of the Project Sky Taxi’s master plan with its predecessors as activity I
(The civil engineering scope of work). The end date of activity I in the master plan is 102 weeks
after start date of the project (16-Dec-2022). Therefore, the start date of the electrical,
mechanical and Communication/IT engineering works is also 102nd week (Radwan, 2011).

Part a)
The critical path is the longest possible path that if delayed will affect the overall completion
period of the project. From the paths obtained in table 2.1, the critical path is identified as
AE – DE –≥– HE – FE – JE – KE – PE – QEwith time duration of 38 weeks. This time duration
of the critical path is determined by adding the duration of the individual activities in the path
(Wells & Kloppenborg, 2018).

SKY TAXI PROJECT MANAGEMENT 8
Time duration of path=2+5+4 +4 +5+4+6+ 6+2
Time duration of critical path=38 weeks
Part b)
The slack or float is the time an activity or a network path can be delayed without causing a
delay in the overall Sky Taxi project completion time. Installation of the interruptible power
supply equipment at the main switch room is activity JE.
Critical Path Analysis
Using the critical path analysis, the float of activity JE can be determined and is presented as
follows
Using forward pass – backward pass technique, the critical path activities are first assigned fixed
values of the start and finish dates such that the early start is equal to the late start and the early
finish is equal to the late finish.
The critical path AE – DE –≥– HE – FE – JE – KE – PE – QE can be represented as:
Early Start Duration Early Finish
Activity
Late Start Float Late Finish

SKY TAXI PROJECT MANAGEMENT 9
The activity JE is in the critical path with a float equal to zero hence it cannot be delayed without
affecting the overall project completion (Mayes, 2014).
Part c)
The early start and the early finish of the activity is obtained through the forward pass in the
path. The late start and late finish information can be obtained by doing a backward pass on the
path AE−DE−EE−FE−JE−KE−PE – QE, the longest path containing activity EE- the
upgrade of the 66kV substation at Perth airport docking station.

The float of activity EE is given as:
Floa tEE=Late finish−Early finish
Floa tEE=15−10=5 weeks
The upgrade of the 66kV sub-station at Perth airport docking station can be delayed by 5 weeks
without delaying the completion of the project (Muro, 2017).
Part d)
The installation of the lightning and surge protection equipment is activity NE of the electrical
engineering scope of work. Doing a forward pass on the longest path containing NE, we obtain
the early start and early finish dates. By doing a backward pass considering the critical path
conditions, we obtain the late start and the late finish dates and the slack of activity NE can then
be calculated. The longest path containing activity NE is AE−DE−¿−ME−NE−KE−PE – QE
with time duration of 34 weeks (Muro, 2017).

Floa tNE=30−20=10 weeks
The installation of lighting and surge protection can be delayed by 10 weeks without delaying
the completion of the electrical scope of the project.
Part e)
Installation of all the landing pad lights as per CASA requirements is activity RE of the electrical
engineering scope of work. The longest path containing activity RE is
AE−BE−ℜ−KE−PE – QE with time duration of 27 weeks. Doing a forward pass on this path
of RE, we obtain the early start and early finish dates. By doing a backward pass considering the
critical path conditions, we obtain the late start and the late finish dates and the slack of activity
RE can then be calculated (Muro, 2017).
Floa tℜ=Late finish−Early finish
Floa tℜ=24−13=11 weeks
The installation of the landing pad lights can be delayed by 11 weeks without delaying the
completion of the electrical scope of the project.
