Prepare a project proposal on how to adjust the project schedule. The proposal should include only descriptions of the ways in which you propose to modify the project schedule. Your final project (due in Week 8) will include the following:
- A formal change request
- An evaluation of the impact of the change (as submitted to the Change Control Board)-time and labour only. Note: It will be necessary to create the original project schedule and budget to analyse the impact of the change request. Consider that the additional wing will be built concurrently.
- A list of all the assumptions made
- An analysis of risk factors due to the change request
- A new project schedule that shows:
- The additional time required
- The additional labour cost
- The new completion date
- A statement of work for one contractor
- A contract closure process description for one contractor
- A project closure process description
The project details are as follows:
The Smiths decide to build a house on a piece of land that they have purchased. They have consulted with an architect and have the blueprints created. You are a general contractor and have agreed to build the house for them. The Smiths inform you that they had been considering the addition of an extra wing in the house but have now decided against it as the additional space is unnecessary. The original blueprints that the Smiths gave you did not have the additional wing.
You have projected that it will take you 12 weeks to complete the house. However, you need a buffer to accommodate the uncertain weather conditions, and you tell the Smiths that you will need 14 weeks. The Smiths are really anxious to move into their new house. Although they agree for 14 weeks, they also want to put in a penalty for late completion. You agree, provided they also put in a bonus for early completion. You reach an agreement with the Smiths, and the contract is signed. You have figured the project duration and effort as follows:

Just as your crew starts framing the second floor, the Smiths tell you that they would now like the additional wing in the house they mentioned previously. The Smiths present you with a new set of blueprints, containing the new wing and ask for a projected difference in price and time for the addition.You figure that to add the extra wing the following would be required in terms of duration and effort:
|

This new estimate to add the wing, assumes the sheathing will go on the base house and then work will stop until the extra wing is sheathed. You believe this will be the most economical way to add the additional wing to the property. Another option would be for the project to continue as originally planned, and then add the wing after the Smiths have moved in. After considering both options, the Smiths choose to follow your recommendation to add the new wing now so that they move in when the whole house is complete. The additional work required is as follows:

In this project, you will analyse the situation and the effect of the change request on the schedule, cost, and features.
