Question 1Project Planning and Scheduling

Which scheduling method explicitly models the logical relationships between activities so that the critical path and total float can be calculated?

  1. Line-of-balance chart
  2. Cumulative S-curve chart
  3. Gantt bar chart
  4. CPM precedence diagram Correct answer.

Explanation

The precedence diagram method links each activity to its predecessors and successors with defined relationships, then forward-passes early dates and backward-passes late dates. Those passes produce the longest path, which is the critical path, and a float value for every activity. Bar charts, line-of-balance, and S-curves display time or progress but do not compute logic-driven float.

Question 2Project Planning and Scheduling

In CPM scheduling, total float on an activity is best described as:

  1. the time an activity can slip without delaying its immediate successor
  2. the waiting period inserted between a predecessor and a successor
  3. the time an activity can slip without delaying project completion Correct answer.
  4. the gap between the budgeted and the actual duration of an activity

Explanation

Total float is the amount of time an activity can be delayed from its early start without delaying the project finish date or violating a schedule constraint. It is computed as late finish minus early finish, or late start minus early start. Free float is the narrower measure that protects only the immediate successor's early start.

Question 3Project Planning and Scheduling

An activity is on the critical path of a CPM network when:

  1. it carries the largest budgeted cost in the schedule
  2. it has the greatest number of predecessors
  3. its total float equals zero Correct answer.
  4. it has the longest single duration in the project

Explanation

The critical path is the longest continuous chain of dependent activities through the network, so it sets the shortest possible project duration. Every activity on that chain has zero total float, meaning any delay pushes completion unless the logic is changed. Cost, single-activity duration, and predecessor count do not by themselves make an activity critical.

Question 4Project Planning and Scheduling

A finish-to-start relationship with a five-day lag between Activity A and Activity B means that:

  1. B starts five days after A finishes Correct answer.
  2. A and B may overlap by five working days
  3. B may start five days before A finishes
  4. A must finish five days after B starts

Explanation

In a finish-to-start relationship the successor's start is tied to the predecessor's finish, and a positive lag inserts waiting time between the two events. A five-day lag therefore places B's early start five working days after A's finish. A negative lag, called a lead, would instead allow the activities to overlap.

Question 5Project Planning and Scheduling

Schedule compression by crashing differs from fast-tracking mainly because crashing:

  1. adds resources to shorten durations at extra cost Correct answer.
  2. extends the working calendar by adding weekend shifts
  3. reduces the scope of work to meet the completion date
  4. overlaps sequential activities, increasing rework risk

Explanation

Crashing shortens activity durations by adding resources such as crews, shifts, or equipment, which almost always raises cost and can reduce productivity through crowding. Fast-tracking instead overlaps activities that were planned in sequence, accepting coordination and rework risk. Neither technique is permitted to change the contracted scope of work.

Question 6Project Planning and Scheduling

Resource leveling applied to a network that has limited float will typically:

  1. may extend the project duration if the limit binds Correct answer.
  2. always shortens the overall project completion duration
  3. never changes any planned activity start date
  4. shifts the critical path to the lowest-cost chain

Explanation

Resource leveling adjusts start and finish dates so demand stays within limits on crews, equipment, or key personnel. When those limits cannot be met within existing float, leveling pushes work past its late dates and can lengthen the project. Resource smoothing, by contrast, stays within float and protects the completion date.

Question 7Project Planning and Scheduling

After the baseline schedule has been approved, the monthly schedule update should:

  1. replace the CPM network with a bar chart for simplicity
  2. record actuals and remaining durations, then reforecast Correct answer.
  3. overwrite the baseline so that variances no longer appear
  4. recalculate the baseline using the original activity durations

Explanation

A schedule update preserves the approved baseline while recording actual start and finish dates, remaining durations, and revised logic for incomplete work. The forecast completion is then recalculated from the data date forward through the network. Overwriting the baseline destroys the benchmark needed for delay analysis and progress measurement.

Question 8Project Planning and Scheduling

A three-week look-ahead schedule is most valuable to a superintendent because:

  1. it measures earned value for monthly progress payments
  2. it clears near-term constraints before crews mobilize Correct answer.
  3. it replaces the master baseline schedule for the whole project
  4. it sets the contractual completion date for the work

Explanation

The look-ahead is a short-interval planning tool that breaks the coming weeks into assignable work and removes constraints before crews arrive. Planners verify materials, submittals, permits, equipment, and completion of predecessor work so the weekly plan is achievable. It supplements, but never replaces, the master baseline schedule.

Question 9Project Planning and Scheduling

An owner-directed design change delays a critical activity by 12 days. In the same period a contractor-caused delay of 5 days occurs on a non-critical activity that has 8 days of total float. Under a time-impact analysis, the time extension due is:

  1. 5 days
  2. 7 days
  3. 0 days
  4. 12 days Correct answer.

Explanation

Relief is granted only for delay that actually pushes the project completion date. The owner-caused change consumed 12 days on the critical path and therefore extended completion by 12 days, while the contractor's 5-day delay was absorbed by the 8 days of float on a non-critical path. The compensable extension is therefore 12 days.

Question 10Project Planning and Scheduling

An activity has an early start of day 8 and a duration of 6 days. The backward pass gives it a late finish of day 18. What is the activity's total float?

  1. 0 days
  2. 4 days Correct answer.
  3. 10 days
  4. 6 days

Explanation

Total float equals late finish minus early finish, and early finish equals early start plus duration, giving day 14 here. Subtracting the early finish of day 14 from the late finish of day 18 leaves 4 days of total float. The backward pass derives late dates from the project completion date, so the result measures slack before completion is affected.

Question 11Project Planning and Scheduling

In a work breakdown structure developed for a construction project, the lowest level at which scope can be planned, scheduled, and controlled is best described as:

  1. A cost code shared across the whole site
  2. A project phase reported to the owner
  3. A work package assigned to one responsible crew Correct answer.
  4. A summary bar that rolls up several trades

Explanation

The work breakdown structure decomposes project scope into progressively smaller deliverables, and the lowest level of that hierarchy is the work package. A work package has a defined scope, a single responsible party, and a duration and cost that can be measured and updated, which makes it the basic building block of the schedule.

Question 12Project Planning and Scheduling

Which statement best describes a milestone in a construction schedule?

  1. It groups all trades working on one floor into a single bar
  2. It consumes schedule contingency held in the project reserve
  3. It marks a significant event and carries no duration or resources Correct answer.
  4. It represents the longest continuous path through the network

Explanation

A milestone flags a significant point in the project, such as substantial completion or the start of commissioning, and is normally shown with zero duration and no resources. Because it has no duration of its own it cannot be compressed and cannot be delayed by its own work; it simply records the date by which the preceding activities must finish.

Question 13Project Planning and Scheduling

A superintendent reviewing a bar chart (Gantt) schedule should recognize that its principal limitation compared with a logic network is that it:

  1. Requires software that trade contractors rarely have access to
  2. Shows timing but not the logic that drives the sequence Correct answer.
  3. Cannot show planned start and finish dates for individual activities
  4. Cannot be updated once construction has started on site

Explanation

A bar chart displays when each activity is planned to occur, but the dependencies between bars are not explicit, so the reader cannot see which activity is actually driving the sequence. A logic network shows those relationships and allows float and the critical path to be calculated, which is why it is preferred for delay analysis and re-sequencing.

Question 14Project Planning and Scheduling

A formwork activity is measured using a rule of credit that assigns 60 percent of its value to erection and 40 percent to stripping. At the cut-off date the crew has erected 80 percent of the formwork and stripped 20 percent. The reported percent complete for the activity is:

  1. 80 percent
  2. 60 percent
  3. 56 percent Correct answer.
  4. 50 percent

Explanation

Rules of credit weight each step of an activity so that reported progress reflects value earned rather than time elapsed. Applying the weights gives (0.60 x 80) + (0.40 x 20) = 48 + 8 = 56 percent complete for the activity as a whole.

Question 15Project Planning and Scheduling

At a progress cut-off the schedule reports a planned value (BCWS) of $480,000 and an earned value (BCWP) of $420,000. The schedule performance index is:

  1. 0.600
  2. 0.875 Correct answer.
  3. 1.143
  4. 1.000

Explanation

The schedule performance index is earned value divided by planned value, so 420,000 divided by 480,000 equals 0.875. A result below 1.0 means less work has been earned than was planned for the period, which indicates the project is running behind schedule.

Question 16Project Planning and Scheduling

The structural steel package must be released for fabrication 22 weeks before erection begins, and erection is scheduled to start at the beginning of project week 40. In which project week must the steel be released?

  1. Week 40
  2. Week 18 Correct answer.
  3. Week 62
  4. Week 22

Explanation

The release date is found by subtracting the fabrication lead time from the required on-site date: 40 minus 22 gives week 18. The procurement schedule must also tie that release date to the shop drawing and approval activities that precede it, so that any review delay is visible while there is still time to react.

Question 17Project Planning and Scheduling

A schedule is built on a seven-day work calendar, but the contract states that weather days are non-compensable and the site historically loses eight days per month to rain. The most appropriate treatment in the baseline schedule is to:

  1. Omit weather from the baseline because lost days are non-compensable
  2. Add a single lump-sum weather activity spanning the whole project
  3. Include the historical loss in affected activities' calendars or durations Correct answer.
  4. Schedule every weather-sensitive activity in the driest month

Explanation

Where the contract makes weather days non-compensable, the contractor carries that risk, so the baseline must already contain a realistic allowance for it. The usual practice is to extend the durations or adjust the calendars of weather-sensitive activities by the historical loss, rather than trying to claim the time after it has been lost.

Question 18Project Planning and Scheduling

Which item belongs in the schedule basis document prepared with the baseline schedule?

  1. The subcontractor's confidential bid markup by activity
  2. The daily manpower log from the previous reporting period
  3. The calendars, constraints, assumptions, and key dates used Correct answer.
  4. The list of RFIs issued after baseline approval

Explanation

The schedule basis records the assumptions behind the baseline: calendars and shifts, imposed constraints, key dates, sequencing decisions, and the source of activity durations. It lets a reviewer, or a superintendent who inherits the project, understand why the schedule was built as it was and test any proposed change against those assumptions.

Question 19Project Planning and Scheduling

A change adds work to an activity that has 10 days of total float. A time impact analysis using a fragnet inserted into the current update shows the activity's float falling to 3 days. The appropriate response is to:

  1. Reject the change because the activity is not on the critical path
  2. Award a 7-day time extension because 7 days of float were consumed
  3. Approve the change with no time extension, since completion is unaffected Correct answer.
  4. Award a 7-day extension only if the owner caused the added work

Explanation

A time impact analysis measures the effect of a change on the project completion date, not on a single activity's float. Here 7 days of float are consumed but 3 remain, so the critical path and the completion date are unchanged; the change is approved without a time extension while the reduced float is recorded for future delay analysis.

Question 20Project Planning and Scheduling

A Monte Carlo schedule risk analysis of the baseline returns a P50 of 210 working days and a P80 of 228 working days. Which statement about these results is correct?

  1. The 18-day spread measures the accuracy of the estimate
  2. There is a 30 percent probability of finishing within 210 working days
  3. There is an 80 percent probability of finishing within 228 working days Correct answer.
  4. The project is certain to finish in exactly 210 working days

Explanation

A P80 result means that in 80 percent of the simulated outcomes the project finished on or before that duration, so 228 working days carries an 80 percent confidence of being met. The P50 is the median outcome rather than a certainty, and the spread between the two reflects the combined effect of all the risks and uncertainties that were modelled.

Question 21Project Planning and Scheduling

In a CPM schedule review, an activity that has no predecessor and no successor is best described as:

  1. a summary activity with rolled-up dates
  2. a completed activity with zero remaining duration
  3. an open-ended activity with missing logic Correct answer.
  4. a critical activity with no total float

Explanation

Open ends occur when an activity lacks a logical tie to a predecessor or successor. They can distort float and critical path calculations, so they should be closed before the baseline schedule is approved.

Question 22Project Planning and Scheduling

When a five-day workweek calendar with holidays is assigned to an activity, the scheduling software uses that calendar to:

  1. exclude nonwork days from the activity's calculated dates Correct answer.
  2. ignore the activity's predecessor relationships
  3. shorten the activity duration by the number of holidays
  4. convert the activity into a milestone on holidays

Explanation

A calendar defines which days are workdays. Assigning it causes the software to skip weekends and listed holidays when calculating start and finish dates, without changing the entered duration in workdays.

Question 23Project Planning and Scheduling

The WBS dictionary adds which information to a work package shown on a work breakdown structure?

  1. The name of the project superintendent and key contacts
  2. The as-built drawing revision history
  3. The scope, deliverables, and acceptance criteria Correct answer.
  4. The daily weather forecast for the package

Explanation

The WBS dictionary describes each work package in detail, including scope boundaries, deliverables, responsible party, and acceptance criteria. This lets estimators and schedulers interpret the package consistently.

Question 24Project Planning and Scheduling

Activity B has an early finish of day 15. Its only successor, Activity C, has an early start of day 19. What is B's free float?

  1. 0 days
  2. 2 days
  3. 4 days Correct answer.
  4. 15 days

Explanation

Free float is the time an activity can be delayed without delaying the early start of any successor. Here, 19 minus 15 equals 4 days of free float.

Question 25Project Planning and Scheduling

A schedule update shows that a successor started before its predecessor finished. Which update option preserves the original network logic and prevents the successor from being driven by out-of-sequence dates?

  1. Retained logic Correct answer.
  2. Open-ended logic
  3. Actual dates only
  4. Progress override

Explanation

Retained logic keeps the planned predecessor-successor ties and recalculates remaining work from the data date, resisting out-of-sequence progress. Progress override lets actual dates break logic.

Question 26Project Planning and Scheduling

For a repetitive operation such as paving a long roadway with crews moving from station to station, which scheduling technique best highlights crew continuity and location-based progress?

  1. A responsibility assignment matrix
  2. A line-of-balance schedule Correct answer.
  3. A resource histogram
  4. A Monte Carlo simulation

Explanation

Linear schedules plot activities against location or distance and show production slopes. Parallel slopes reveal crew continuity and location conflicts better than a bar chart.

Question 27Project Planning and Scheduling

A critical structural activity cannot start until a shop drawing is approved. How should the review period be represented in the construction schedule?

  1. As a logic-tied review activity Correct answer.
  2. As a milestone after completion
  3. As a lag on the predecessor
  4. As a narrative note only

Explanation

The review duration is real work that can delay the critical activity, so it should appear as an activity with predecessor and successor logic. A note or fixed lag would hide responsibility and timing.

Question 28Project Planning and Scheduling

A master summary schedule is most appropriate for:

  1. communicating major milestones to executives Correct answer.
  2. calculating total float for each work package
  3. replacing the detailed construction schedule
  4. directing daily crew assignments

Explanation

Summary and master schedules roll up detailed activities into major phases and milestones for management communication. They lack the granularity needed for crew direction or activity-level float analysis.

Question 29Project Planning and Scheduling

A relationship is modeled with a negative lag of three days between two activities. This negative lag is equivalent to:

  1. a lead that allows the successor to start earlier Correct answer.
  2. a three-day extension of the predecessor's duration
  3. a three-day increase in total float
  4. a mandatory finish-to-finish relationship

Explanation

A negative lag, or lead, overlaps the successor with the predecessor by three days. It does not change activity durations or float, but it can create logic that is difficult to manage in the field.

Question 30Project Planning and Scheduling

Resource smoothing differs from resource leveling mainly because smoothing:

  1. extends the project completion date to remove all peaks
  2. requires crashing every activity on the critical path
  3. uses float to reduce peaks without delaying completion Correct answer.
  4. replaces the critical path with a resource-driven path

Explanation

Smoothing seeks a more even resource profile within existing float and does not intentionally move the completion date. Leveling, by contrast, may delay activities and extend the project when resources are constrained.

Question 31Project Planning and Scheduling

On a commercial project the master CPM schedule shows a 60-week duration. The site team also maintains a short-interval look-ahead schedule. What is the primary purpose of that look-ahead?

  1. It sets the milestone dates that the owner uses to judge substantial completion under the contract.
  2. It replaces the baseline CPM schedule as the contractual instrument for measuring progress payment quantities and for assessing liquidated damages if the owner terminates the contract.
  3. It extends each activity duration by three weeks so that weather and permitting delays are absorbed without changing the critical path.
  4. It converts near-term work into crew-level plans and exposes constraints to clear before work starts. Correct answer.

Explanation

A short-interval look-ahead translates the master schedule into workable plans, typically covering three to six weeks, that foremen help build and commit to. Its central purpose is constraint removal: confirming drawings, materials, permits, access, and preceding work are in place before a crew is scheduled to start. It is a planning and coordination tool, updated weekly, not a contractual control document.

Question 32Project Planning and Scheduling

A planner uses a three-point estimate for an uncertain excavation activity: optimistic 10 working days, most likely 16 working days, pessimistic 28 working days. Using the standard PERT weighted formula, what expected duration should be entered in the schedule?

  1. 19 working days
  2. 17 working days Correct answer.
  3. 18 working days
  4. 16 working days

Explanation

The PERT expected duration weights the most likely value four times and gives the optimistic and pessimistic values one weight each: (10 + 4 x 16 + 28) / 6 = 102 / 6 = 17 working days. This weighting reflects that the most likely outcome is the most probable single value, while the extremes are possible but far less likely.

Question 33Project Planning and Scheduling

A project is four weeks behind after a month of rain, and the owner refuses any extension of contract time. The contractor proposes to frame the third floor while mechanical rough-in is still underway on the second floor, instead of completing each floor in sequence. Which technique is being used, and what is its principal schedule risk?

  1. Linear scheduling; the risk is that production rates for the mechanical and framing crews will diverge and the buffer between them will have to be recalculated for every floor of the building.
  2. Fast-tracking; the risk is that overlapping trades cause interference, rework, and safety conflicts that can consume the time saved. Correct answer.
  3. Crashing; the risk is that premium labour and overtime costs escalate beyond the acceleration budget.
  4. Resource leveling; the risk is that peak crew demand is flattened and trades must idle between floors.

Explanation

Overlapping phases or activities that were planned to run in sequence is fast-tracking. It can recover time without the premium labour cost of overtime, but the recovered time is bought with risk: trades working in the same space interfere, installed work may be damaged or redone, and safety exposure rises, so gains often erode.

Question 34Project Planning and Scheduling

A contractor claims 45 working days of delay. The accepted baseline schedule was never updated during the claim period and no fragnets were prepared at the time, but contemporaneous daily reports, concrete delivery tickets, and inspection logs are available. Which delay analysis approach is most defensible?

  1. An as-planned versus as-built comparison that uses contemporaneous records to establish actual start and finish dates for the affected work. Correct answer.
  2. A comparison between the contract completion date and the completion date shown on the contractor's current, recently updated schedule.
  3. A prospective time impact analysis that inserts a fragnet for each delay event into the accepted baseline schedule, without adjusting that baseline to the status at the time of each event.
  4. A windows analysis that relies on the monthly schedule updates the contractor issued during the delay period.

Explanation

When no schedule updates or contemporaneous fragnets exist, the delay must be reconstructed from records. Comparing the as-planned logic and dates with as-built dates established from daily reports, delivery tickets, and inspection logs is the standard defensible method, because it relies on contemporaneous evidence rather than hindsight assumptions about what the schedule would have shown.

Question 35Cost Management and Estimating

What is the main purpose of a contingency allowance in a construction estimate?

  1. To replace the need for a detailed quantity takeoff
  2. To fund owner-directed changes that expand the project scope
  3. To increase the contractor's profit margin on the bid
  4. To cover unforeseen costs that fall within the defined project scope Correct answer.

Explanation

Contingency is a planned reserve for unknown costs that may arise within the agreed scope, such as minor design gaps, weather delays, or price fluctuations. It is not profit and does not cover scope growth, which should be priced through change orders. A quantity takeoff is still required to build the base estimate.

Question 36Cost Management and Estimating

How is the direct labor cost for an activity calculated in a detailed estimate?

  1. Equipment hours times the operator wage rate
  2. Material quantity times the labor productivity rate
  3. Labor hours times the burdened hourly wage rate Correct answer.
  4. Crew size multiplied by the expected project duration

Explanation

Direct labor cost equals the estimated labor hours for the activity multiplied by the hourly wage plus labor burden, such as payroll taxes, insurance, and benefits. Productivity determines the hours, but the cost requires the burdened rate. Crew size and duration help derive hours but do not by themselves give labor cost.

Question 37Cost Management and Estimating

A takeoff shows 200 square metres of wall finish is required. The estimator applies a 5% waste factor. How much finish should be purchased?

  1. 220 square metres
  2. 200 square metres
  3. 210 square metres Correct answer.
  4. 190 square metres

Explanation

A waste factor is added to the net measured quantity to account for cutting, breakage, and offcuts. Multiply 200 square metres by 1.05, which equals 210 square metres. Subtracting waste or ignoring it would under-order material.

Question 38Cost Management and Estimating

Which of the following is normally classified as a project indirect cost in a construction estimate?

  1. Structural steel supplied for the building frame
  2. Ready-mix concrete placed in the footings
  3. Rental of the site office trailer Correct answer.
  4. Wages of carpenters installing formwork

Explanation

Indirect costs support the project as a whole rather than a specific work item. Site office rental, supervision, temporary utilities, and security are typical project indirect costs. Materials and direct trade labor are charged directly to the work items they belong to.

Question 39Cost Management and Estimating

A contractor has direct costs of $250,000. Overhead is 12% of direct costs, and profit is 8% of the total of direct costs plus overhead. What is the bid price?

  1. $302,400 Correct answer.
  2. $324,000
  3. $300,000
  4. $280,000

Explanation

Overhead is 12% of $250,000, or $30,000, giving a subtotal of $280,000. Profit is 8% of that subtotal, or $22,400, so the bid price is $302,400. Applying profit only to direct cost or omitting overhead would understate the bid.

Question 40Cost Management and Estimating

A superintendent receives a verbal instruction from the owner's representative to perform extra work. What is the most appropriate action to support later cost recovery?

  1. Perform the work and rely on the verbal instruction as authorization
  2. Charge the extra work to an existing bid item with available funds
  3. Confirm the instruction in writing and keep daily cost records Correct answer.
  4. Refuse to perform any extra work until a formal change order is signed

Explanation

Verbal direction should be confirmed in writing promptly, and the superintendent should keep daily records of the extra labor, equipment, and materials. This documentation supports pricing and proves the cost if the change order is negotiated later. Performing work without records weakens the claim.

Question 41Cost Management and Estimating

A cost report shows budgeted cost of work performed of $120,000 and actual cost of work performed of $135,000. What does the cost variance indicate?

  1. The project is $15,000 under budget
  2. The project is $15,000 over budget Correct answer.
  3. The project is on budget
  4. The project has earned $15,000 in additional profit

Explanation

Cost variance is budgeted cost of work performed minus actual cost of work performed, or $120,000 minus $135,000, which equals negative $15,000. A negative cost variance means the work performed cost more than planned. The project is therefore over budget by $15,000.

Question 42Cost Management and Estimating

An activity was estimated at 8 labor hours per unit, but field records show 10 labor hours per unit. What is the percentage increase in labor hours per unit?

  1. 10%
  2. 25% Correct answer.
  3. 8%
  4. 20%

Explanation

The increase is 10 minus 8, or 2 hours per unit. Divide the increase by the original estimate of 8 hours and multiply by 100, which gives 25%. Comparing the increase to the actual hours instead would incorrectly give 20%.

Question 43Cost Management and Estimating

A crew of four workers earns $45 per hour each, and one foreman earns $60 per hour. The crew works an 8-hour day and installs 20 units. With a 25% labor burden on all wages, what is the burdened labor cost per unit?

  1. $108.00
  2. $96.00
  3. $120.00 Correct answer.
  4. $150.00

Explanation

Daily wages are four workers at $45 for 8 hours, or $1,440, plus the foreman at $60 for 8 hours, or $480, for a base of $1,920. Adding 25% burden gives $2,400. Dividing by 20 units gives $120 per unit.

Question 44Cost Management and Estimating

A project has a budget at completion of $2,000,000. Work worth $800,000 has been earned, and actual costs to date are $900,000. What is the cost performance index, and what does it show?

  1. 1.13, indicating the project is over budget
  2. 0.89, indicating the project is over budget Correct answer.
  3. 0.89, indicating the project is under budget
  4. 1.13, indicating the project is under budget

Explanation

Cost performance index is earned value divided by actual cost, or $800,000 divided by $900,000, which equals about 0.89. A CPI below 1.0 means each dollar spent is producing less than one dollar of earned value, so the project is over budget. Values above 1.0 would indicate favorable cost performance.

Question 45Cost Management and Estimating

In a project cost-control system, which work breakdown structure level is normally used to assign a budget and make one person accountable for cost performance?

  1. The program portfolio level
  2. The contract total level
  3. The project summary level
  4. The work package Correct answer.

Explanation

A work package is the lowest practical WBS level for assigning scope, budget, schedule, and a responsible owner. Higher summary levels aggregate many work packages and are too broad for day-to-day cost control.

Question 46Cost Management and Estimating

Which item is classified as an ownership cost when a contractor uses a piece of heavy construction equipment?

  1. Fuel consumed during operation
  2. Insurance on the machine Correct answer.
  3. Wages of the equipment operator
  4. Routine maintenance and repairs

Explanation

Ownership costs arise from having the machine available and include depreciation, insurance, taxes, and the cost of capital. Fuel, operator wages, and routine repairs are operating costs incurred when the machine is used.

Question 47Cost Management and Estimating

Under a unit-price construction contract, the contractor is paid mainly according to which basis?

  1. A guaranteed maximum price established by the owner
  2. Actual cost plus a fee agreed with the owner
  3. Measured quantities times bid unit rates Correct answer.
  4. A fixed lump sum for the entire completed facility

Explanation

A unit-price contract pays for actual measured work at the contractor's bid unit rates, so the final amount varies with quantities. Lump sum and cost-plus arrangements use different payment mechanisms.

Question 48Cost Management and Estimating

A contractor is preparing a bid for work that will be performed over 18 months in a period of expected inflation. Which allowance is specifically intended to cover the anticipated rise in labor and material prices?

  1. Escalation allowance Correct answer.
  2. Contingency allowance for unknown conditions
  3. Equipment depreciation reserve
  4. Retention held by the owner

Question 49Cost Management and Estimating

A project has a planned value of $200,000 and an earned value of $180,000 at the data date. What is the schedule performance index (SPI)?

  1. 1.05
  2. 0.95
  3. 1.11
  4. 0.90 Correct answer.

Explanation

SPI equals earned value divided by planned value, so $180,000 divided by $200,000 gives 0.90. A result below 1.0 indicates that less work has been earned than was planned for the date.

Question 50Cost Management and Estimating

A contractor wants a profit margin of 12% of the selling price. What markup percentage must be applied to cost to achieve that margin?

  1. 15.0%
  2. 12.0%
  3. 13.6% Correct answer.
  4. 10.7%

Explanation

Markup on cost equals margin divided by one minus the margin, so 0.12 divided by 0.88 equals about 13.6%. Using 12% as the markup would produce a margin below 12% of the selling price.
