Practical scenario
Your project schedule has slipped. You must compute the critical path, find total float on a lagging activity and evaluate earned value.
Why this matters
Construction content covers scheduling, estimating, controls and safety — practical knowledge you also need for capstone implementation planning.
Concept explanation
- CPM determines the longest path through the network; activities on it have zero total float.
- Forward pass gives early start and finish; backward pass gives late start and finish.
- Earned value compares budgeted, earned and actual cost to diagnose schedule and cost performance.
- Quantity takeoff plus unit costs plus indirect costs and markup gives the bid price.
Unit guidance
- Write units on every substituted value.
- Cancel units symbolically before evaluating numbers.
- Confirm the result unit matches the quantity you were asked for.
Handbook navigation
- Open the Construction Engineering section of the handbook.
- Search the term "project administration" rather than scrolling.
- Note the equation number so you can return to it quickly.
Calculator guidance
- Confirm angle mode before any trig entry.
- Store intermediate values in memory instead of re-keying rounded numbers.
- Round only at the final answer.
FE strategy
- Draw the network and do the forward pass before answering anything about float.
- CPI and SPI below 1.0 always mean trouble.
Conceptual example
A conceptual construction engineering item will ask which quantity increases, decreases, or stays the same when one input changes. Reason from the governing relationship, not from memory of a numeric answer.
Common mistakes
- Confusing total float with free float.
- Assuming the longest activity is on the critical path.
- Reading CPI below 1.0 as good performance.
Guided practice
- Work the first worked example with the solution visible.
- Re-solve it closed-book and compare every step.
- Explain the unit cancellation out loud.
Independent practice
- Complete a 10-question Construction Engineering quiz in practice mode.
- Classify every miss by error category.
- Re-test the missed subtopic within 48 hours.
Summary
- Critical path activities have zero total float.
- CPI = EV/AC; below 1.0 means over budget.
- Float belongs to the schedule, not to a party, unless the contract says otherwise.
