Assignment #2 MGMT 3020 Bakersfield Pools is about to work on a project to install a backyard pool and build an accompanying bathhouse. The installation process is fairly well defined. Building the pool involves digging the foundation, pouring concrete, and ordering and installing a filtration system. The bathhouse work involves constructing the bathhouse, installing the additional required plumbing, and installing the necessary electrical work. The process is shown in the table below.

Ignore the possibility of crashing until part f). a) Draw the network diagram for the project. Calculate early start, early finish, late start, late finish, and slack times. b) Bakersfield Pools works all 7 days a week. The customer wants this pool completed in time for a birthday party in 27 days. Can it be done? Why or why not? (Note: this means the entire project must be completed.) c) The staff member who is in charge of pouring concrete wants to go on a two-week vacation starting in 12 days. Can Bakersfield Pools let him go when he wants? Why or why not? d) Equipment required to do task E (the installation of the filtration system) is currently undergoing repairs. Until it is repaired, no work can be done on task E. What is the latest day those repairs can be completed by without delaying the project? e) BP's regular electrician is on vacation, and a "temp" has been hired. The temporary electrician is not as productive as the regular electrician. Suppose it takes him 4 days to install the electrical wiring, as opposed to 2 days. Does this delay the project?
