Unit 5 Construction Schedule
[Instructor Name]
[Date]
Station 2, its activities, durations and calendar are composite and illustrative; the schedule was computed with a short script whose logic is described; the sources cited are real.
Method
The schedule uses the critical path method. Each of 29 activities has a duration in working days and one or more predecessors, all finish-to-start. A forward pass from notice to proceed fixes each activity's earliest dates. A backward pass from day 232 then shows how late each could start before completion moves. Total float is what separates those two dates. Hinze (2012) describes this method as the core of construction scheduling because it identifies which activities control the finish date. The passes were run with a short script, and its output is appended to the schedule so any reviewer can check the arithmetic.
The calendar is a five-day week. Eight rain days anticipated for March and April are entered as nonwork days on the calendar rather than added to the durations of outdoor activities. That keeps durations honest and makes clear, if more rain falls, how much of the allowance has been used. The scheduling practice standard recommends modeling known nonwork periods in the calendar rather than inflating durations (Project Management Institute, 2019).
The Activity Table
Below, every activity appears with its working-day duration and the float the passes produced. Activities with zero float are critical.
Critical activities, 18 in all:
A Notice to proceed and mobilization: 5 days
B Site clearing and erosion control: 6
F Bay undercut, fill and footings: 12
D Foundation inspection: 2
E Wing foundation walls: 10
H Underslab plumbing and electrical: 12
I Underslab inspection: 2
J Wing slab on grade: 6
K Wing light-gauge framing and roof trusses: 10
L Wing roof deck and roofing: 12
M Wing exterior walls and veneer: 15
N Wing mechanical, plumbing and electrical rough-in: 25
O Rough-in inspection: 4
P Insulation and drywall: 20
Q Interior finishes: 40
R Wing mechanical and electrical trim and equipment: 18
S Final inspection and certificate of occupancy: 8
T Punch list and closeout: 25
These total 232 working days. The four inspections, foundation, underslab, rough-in and final, account for 16 of them.
Noncritical activities, 11 in all, with total float:
C Wing excavation and footings: 11 days; float 1
Z Sectional door submittals and fabrication: 100 days from notice to proceed; float 8
Y1 Sectional door installation: 6; float 8
Y2 Bay mechanical, electrical and exhaust system: 45; float 8
Y3 Bay finishes, gear lockers and equipment: 40; float 8
V Bay block walls: 36; float 23
W Bay joist and deck erection: 8; float 23
X Bay roofing and bay slab: 16; float 23
U Joist and deck submittals and fabrication: 55 days from notice to proceed; float 29
AB Paving and aprons: 15; float 99
AA Site utilities: 20; float 153
Why the Wing, Not the Masonry
The apparatus bay's block walls are the most visible work on the site, 7,070 units laid over 36 days, and a first guess would put them on the critical path. The computation says otherwise. The bay's sequence, block walls, joists, roof, doors, exhaust system and finishes, finishes 23 days before it must, because the bay's interior work is simpler than the wing's. The living wing carries bunk rooms, a kitchen, bathrooms, offices and a training room, with dense mechanical, plumbing and electrical work, two inspections of its own and forty days of interior finishes. Its chain controls the finish.
The loudest work on the site is not the work that sets the date.
The Bar Chart
The bar chart shows all 29 activities on the five-day calendar, with the eighteen zero-float bars drawn heavier and each noncritical bar trailed by a thin line marking its float. The eight rain days appear as gray columns in March and April. Inspections appear as their own short bars, since an inspection that slips by a day delays everything after it.
Procurement
Two procurement activities start at notice to proceed. Joists and deck need 55 days for submittals, approval and fabrication, and have 29 days of float. Sectional doors need 100 days and have only 8, which makes them the most likely noncritical item to become critical. The doors' float depends on the structural answer to the lintel question from the document review; a late answer that delays door fabrication by more than 8 days would move the finish date.
Near-Critical Activities
Four activities deserve watching beside the critical path. Wing excavation carries a single day of float and sits in the rainy months. The three door-related activities share 8 days. Halpin et al. (2017) recommend tracking near-critical paths as closely as the critical one, because a small slip can make them controlling.
Appendix: The Script
The script reads a table of activities, durations and predecessors, runs the forward and backward passes and prints each activity's early and late dates and total float. Changing one duration and rerunning it shows at once whether the change affects the finish.

The Purdue Global MT281 Unit 5 instructions
The fifth unit asks students to build a construction schedule for their project and identify its critical path. Give every activity a duration and the activities it waits for, then compute how early each can start and how far it can slide without moving the finish. Many sections accept a spreadsheet or short script, if its output is included. The prompt usually expects a logic diagram, a bar chart on a working calendar and a float table for noncritical work. Decide how weather will be handled, as nonwork days or inside durations, and say why. Show procurement and inspections as their own activities. Explain any surprise in the critical path. Eight pages with tables and an appendix, citing scheduling sources, is a typical format.
How the MT 281 Unit 5 example is put together
The schedule explains the critical path method and the script, citing Hinze. A paragraph sets the five-day calendar and puts eight rain days in it as nonwork days, with the scheduling standard. The activity table lists 18 critical activities totaling 232 days, then 11 noncritical ones with their float, under a margin note on telling the superintendent how much slip each can absorb. A section explains why the living wing, not the masonry, controls, with the highlighted line about the loudest work on the site. The bar chart, procurement for joists and doors and near-critical activities follow, citing Halpin and colleagues. An appendix describes the script, under a final note.
Where the points sit in the MT281 Unit 5 rubric
Construction schedules earn marks for correct logic, accurate passes, a clearly identified critical path and useful float information. Instructors reward schedules whose arithmetic can be checked, through a table or appended script. Showing inspections and procurement as activities, rather than hiding them in other durations, earns credit because both often control real projects. A stated method for weather shows judgment. Explaining a critical path that differs from intuition, with the reason, demonstrates analysis. Flagging near-critical activities such as long-lead procurement shows awareness of risk. A readable bar chart, a float table and accurate citations complete the rubric. The schedule's calendar should be stated too, including holidays and weather days, to be stated, since every date depends on it.
MT281 Unit 5 help from the desk
The most common mistake is listing activities in sequence without real predecessors, which makes everything critical. Another is building weather into each duration so that nobody can tell how much allowance remains. Some schedules omit procurement, then discover in the field that doors or joists arrive late. Others treat inspections as instant. Check that the critical path's durations add up to the project length. Share the activities and how long each takes, and a writer will compute the dates, mark the zero-float chain and list the float for everything else. Include procurement lead times, since long-lead items often end up nearer the critical path than expected.

MT281 Unit 5 questions, answered
Should weather be built into durations or shown separately?
Separately is easier to defend. Removing expected rain days from the working calendar, based on local records, keeps each duration an honest estimate and makes it clear when weather exceeds normal. That distinction matters later, because many contracts grant time only for unusual weather, and a schedule that buried normal weather inside durations cannot show the difference.
Do inspections really belong on the schedule?
Yes. Work cannot proceed past a required inspection until it passes, and arranging the inspector's visit takes time that no crew controls. Showing each inspection as an activity with a duration keeps the critical path realistic. In the sample, four inspections account for 16 of the 232 critical days, more than some of the trades they check.
What if the critical path is not what I expected?
Trust the calculation, then check it. An unexpected path often reveals a longer chain nobody was watching, as the living wing does in the sample. Recheck durations and links on the surprising path first; if they hold, the paper should explain why the obvious candidate has float rather than forcing it onto the path.
Where can I find a free MT281 Unit 5 sample paper?
You can read the full MT281 Unit 5 construction schedule here. It schedules 29 fire station activities to 232 working days, finds the critical path through the living wing and lists float for every noncritical activity.
Why do the sectional doors matter so much in the MT281 Unit 5 sample?
They need 100 days of submittals and fabrication from notice to proceed and carry only 8 days of float, so a late lintel answer or delivery slip of more than 8 days would move the finish.
