Greendale Stadium Case

The G&E Company is preparing a bid to build the new 47,000 seat Greendale baseball stadium. The

construction must start July 1, 2011, and be completed in time for the start of the 2014 season. A

penalty clause of $100,000 per day of delay beyond May 20, 2014, is written into the contract.

Ben Keith, the president of the company, expressed optimism at obtaining the contract and revealed

that the company could net as much as $2 million on the project. He also said if they are successful, the

prospects for future projects are quite good since there is a projected renaissance in building classic ball

parks with modern luxury boxes.

ASSIGNMENT

Given the information provided in Table 6.3, construct a network schedule for the stadium project and

answer the following questions:

1. Will the project be able to be completed by the May 20 deadline? How long will it take?

2. What is the critical path for the project?

3. Based on the schedule would you recommend that G&E pursue this contract? Why? Include a

one-page Gantt chart for the stadium schedule.

CASE APPENDIX: TECHNICAL DETAILS OF THE GREENDALE BASEBALL STADIUM

The baseball stadium is an outdoor structure with a retractable roof. The project begins with clearing

the site, an activity that lasts 70 days. Once the site is clear, work can start simultaneously on the

structure itself and demolishing an adjacent building site. This demolition is necessary to create a

construction stage for storing materials and equipment. It will take 30 days to demolish the buildings

and another 70 days to set up the construction site.

The work on the stadium begins by driving 160 support pilings, which will take 120 days. Next comes the

pouring of the concrete bowl (120 days). Once this is done and the construction site has been set up,

then the pouring of the main concourse (120 days), the installation of the playing field (90 days), and the

construction of the upper steel bowl can occur (120 days).

Once the concourse and upper bowl are completed, work can start simultaneously on building the

luxury boxes (90 days), installing the seats (140 days), installing the jumbotron (30 days), and installing

the stadium infrastructure (120 days) which includes: bathrooms, lockers, restaurants, etc. Once the

seats are installed then the steel canopy can be constructed (75 days) followed by the installation of the

lights (30 days).

The retractable roof represents the most significant technically challenge to the project. Building the

roof track supports (90 days) can begin after the lower concrete bowl is constructed. At this time the

dimensions of the roof can be finalized and the construction of the roof at a separate site can begin (180

days). After the roof supports are completed ten the roof tracks can be installed (90 days). Once the

tracks and the roof are completed then the roof can be installed and made operational (90 days). Once

all activities are completed it will take 20 days to inspect the stadium.

For purposes of this case assume the following:

1. The following holidays are observed: January 1, Memorial Day (last Monday in May), July 4 th

,

Labor Day (first Monday in September), Thanksgiving Day (4 th

Thursday in November),

December 25 and 26.

2. If a holiday falls on a Saturday then Friday will be given as an extra day off, and if it falls on a

Sunday them Monday will be given a day off.

3. The construction crew work Monday through Friday
