Assignment 9

Do the following:

1. Make a copy of the Tampa Office Building-01 project. Call it “Tampa Office
Building-09.”
2. Add the preceding activities to the project. You must add AWNE as a new
Responsibility code with the description “Annie's Awnings.” Make activity
1510, Building cleanup, a successor to activity 1107. Also, activity 1107
becomes an additional predecessor to activity 1470, Site work.
The GC is requesting, in addition to the cost of the change order
($10,000), a 3-day extension because the change order “disrupted his plans
and affected other activities.” The owner disputed the time extension.
3. Argue from the contractor's viewpoint: why is this a legitimate request? What
supporting argument would you present? Make any necessary assumptions to
support your point (e.g., contract language, timing of the change order).
4. Argue from the owner's viewpoint: why is this request unacceptable? What
supporting argument would you present? Make any necessary assumptions to
support your point.
