Group Project, Part II
(Module 3) The Control Schedule Process
The baseline project
schedule in MS Project 2013 is contained in the course documents. The start
date (notice to proceed) is set for May 1, 2024 so that the schedule does not
need to be changed during the expected life of this course material. Please
ignore the year. For your convenience, a 2024 calendar is available at the end
of this file. The building inspector requires a three-day window, which can
include weekend days. The building department is very good on performing the
inspections within the three-day window. The schedule has been approved by all
stakeholders. WBS items 3.5 and 3.6 are for two-story houses and were deleted
from this schedule because the San Leo is one story. For consistency, the
remaining WBS numbers are the same as a two-story house.
An Excel workbook: House Schedule of Values is included with
the course materials. This workbook has a WBS Budget that includes the initial
budget for the WBS items. Notice that the roll-up items do not have a subtotal.
You should also refer to the Microsoft Project form: Schedule Compression, to help with your
assignment for this week.
Situation. The project was on or
ahead of schedule during May and June. However, TropicalStorm Cody sat
off the coast, and the jobsite was shut down because of wind, lightning, and/or
rain for the entire first two weeks of July. We were fortunate that lintel and
block inspection passed on June 28. Today is Friday, July 12. It is too wet to
work until Monday, but you have ordered the materials for the roof and the
framing, and all materials will be delivered on Sunday.
You’ve probably heard of
“saving up for a rainy day.” Well, in the home building business, we “save up
to recover from rain delays”.
In the course materials,
there is an Excel workbook that contains the budgeted cost, the planned value,
the percent complete, and the earned value that your team has estimated as of July
12. The sheet has subtotals and formulas for PV, EV, AC, and BAC.
Unfortunately, the other formulas are missing, and you have to recalculate
them.
Your supervisor has asked
you and your project management team to develop a recovery plan to start the
drywall work on time by the end of July. That gives you two weeks to do
essentially four weeks of work. The building department has agreed to inspect
the day you call in for an inspection as long as you pay the $200 overtime fee
per inspection. For weather delays, your company’s policy is to always pay this
additional inspection cost and costs for extra inspections out of general
company overhead so as not to impact your project budget.
To
make up for the weather delay, you’ve talked with the structural engineer
regarding the framing inspection that is required before windows can be
installed. (The building department requires that all structural walls be
completed before any windows are installed).You also talked to the building
officials about installing the windows after the inspection of the load bearing
wall, and they agreed. You don’t need to complete all of the framing, just the
interior load bearing wall shown in Figure 1. You realize that your crew can
erect this in a 12-hour day. The building department will have to inspect this
wall before the windows are installed, but they agreed to do that at 6:00 a.m.
on Tuesday, so that allows you to install windows all day Tuesday. The cost for
the additional inspection will be paid out of company overhead and not charged
to your project.
The
sheeting can be started when half of the trusses are installed, but it will
still take one day after the trusses are installed for the sheeting to be installed.
The inspector has agreed to be there first thing in the morning the next day
after the sheeting is completed.
You can also shorten the
duration for framing, trusses, sheeting, windows, and roofing by working your
crews on overtime pay. You can get up to 12 hours labor per day from your
crews, and they like the overtime pay!
Your
foreman estimated 48 hours total for the framing crew to do all of the framing.
He estimated 32 hours for the trusses. The time for the roofing is 80 hours with
one roofing crew. The windows are 56 hours for one crew. You can also pay these
crews overtime for 4 hours per work day and 12 hours on Saturday at a cost of
$45 additional per hour. (The straight time hourly wages are included in the
budget.) If needed, your crews can work Sunday at double time, which would cost
an additional $90 per hour. (See the Crew Cost spreadsheet for calculations.)
One of your assistants started a spreadsheet in the budget workbook called
“Schedule
Compression” to help develop the cost for the new schedule. She didn’t get it
finished before she went into labor and she will be out for the next 12 weeks.
Assignment:
You will complete the second stage of your
Group Project—The Control Scheduleprocess. Work with your group to prepare
a recovery plan that can be used to bring the project back on schedule. Prepare
a report to your supervisor that provides a detailed description of which tasks
you will crash and/or fast track, the additional cost for crashing and/or
fast-tracking, the revised activity start and end dates, and any other issues
you think should be reported.
Also, explain how crashing
and fast tracking will shorten the schedule. Demonstrate your knowledge of the
core value of responsible stewardship by minimizing the cost for overtime pay.
Please make sure that you
cite and reference all your outside sources properly. You must have a minimum
of three references, including one peer-reviewed journal article.
Even though you complete
this assignment as a group, all students must submit their own paper to
their own individual Dropbox. (This Dropbox basket is linked to Turnitin.)
