Start-to-Finish (SF)
Finish-to-Finish (FF)
Start-to-Start (SS)
Finish-to-Start (FS) (Correct answer)

Correct answer: Finish-to-Start (FS)

A Finish-to-Start relationship means the predecessor activity (roofing) must finish before the successor activity (rough-in MEP) can begin.

Question 3: Which IRC chapter primarily governs the energy efficiency requirements for new residential construction?

Chapter 9 – Roof Assemblies
Chapter 3 – Building Planning
Chapter 11 – Energy Efficiency (Correct answer)
Chapter 4 – Foundations

Correct answer: Chapter 11 – Energy Efficiency

Chapter 11 of the IRC, often cross-referenced with the IECC, establishes energy efficiency requirements for residential buildings.

Question 4: What is the correct response to suspected equipment malfunction?

Continue using with adjusted settings
Remove from service immediately, tag as defective, and report to maintenance (Correct answer)
Let the next shift handle it
Wait for the next scheduled maintenance check

Correct answer: Remove from service immediately, tag as defective, and report to maintenance

Immediately removing malfunctioning equipment from service prevents potential harm and ensures only properly functioning equipment is used for professional services.

Question 5: What does a 'cost-plus-fixed-fee' contract mean for budget management?

The contractor guarantees the project will not exceed a fixed ceiling price
The fee percentage changes based on total project cost
The owner pays actual costs and the contractor receives a predetermined fixed fee on top (Correct answer)
The contractor absorbs all cost overruns above the estimate

Correct answer: The owner pays actual costs and the contractor receives a predetermined fixed fee on top

Cost-plus-fixed-fee contracts reimburse actual costs and add a set fee regardless of final project cost.

Question 6: What is the difference between 'dampproofing' and 'waterproofing' a residential foundation wall?

They are interchangeable terms for the same treatment under the IRC
Waterproofing is applied to the interior and dampproofing to the exterior of the foundation
Dampproofing resists soil moisture vapor only, while waterproofing resists liquid water under hydrostatic pressure (Correct answer)
Dampproofing uses a thicker membrane and is used on below-grade walls only

Correct answer: Dampproofing resists soil moisture vapor only, while waterproofing resists liquid water under hydrostatic pressure

Dampproofing (typically asphalt-based coating) resists moisture vapor transmission only, while waterproofing membranes are engineered to resist liquid water under hydrostatic pressure in high water-table conditions.

Question 7: What is the first step in the risk management process?

Identify potential risks through systematic analysis (Correct answer)
Ignore risks until they become problems
Transfer all risks to third parties
Purchase insurance for all possible risks

Correct answer: Identify potential risks through systematic analysis

Systematic risk identification is the foundational first step, as risks cannot be managed or mitigated until they are identified and understood.

Question 8: A remodel project is 60% complete and has spent $84,000 of a $120,000 budget. What does this indicate about the project's cost performance?

The project is under budget
The project is over budget — 70% of budget used for 60% completion (Correct answer)
No conclusion can be drawn without a schedule analysis
The project is on budget

Correct answer: The project is over budget — 70% of budget used for 60% completion

At 60% completion, expected spend should be $72,000 (60% of $120,000); spending $84,000 means the project is 16.7% over budget at this stage.

Question 9: What is the primary purpose of a building setback requirement?

To establish the maximum allowable building height
To specify minimum insulation R-values
To determine the required number of parking spaces
To control the distance a structure must be from property lines (Correct answer)

Correct answer: To control the distance a structure must be from property lines

Setback requirements, typically found in zoning ordinances, regulate the minimum distance a structure must be placed from property boundaries, roads, and other features.

Question 10: A client requests a scope reduction mid-project to lower costs. The contractor should:

Execute a written deductive change order reducing the contract price accordingly (Correct answer)
Proceed with the reduction and adjust the final invoice
Refuse since the original contract cannot be modified
Complete the original scope and offer a refund later

Correct answer: Execute a written deductive change order reducing the contract price accordingly

A deductive change order formally documents reduced scope and adjusts the contract price, protecting both parties from future disputes.

Question 11: Per the IRC, what is the minimum concrete compressive strength (f'c) required for a residential garage floor slab?

3,000 psi
3,500 psi (Correct answer)

Question 24: Which scheduling technique involves overlapping project phases that were originally planned sequentially to compress the project timeline?

Resource leveling
Fast-tracking (Correct answer)
Milestone scheduling
Schedule crashing

Correct answer: Fast-tracking

Fast-tracking compresses the schedule by performing activities in parallel that were originally planned sequentially, increasing risk.

Question 25: A project manager uses the '80/20 rule' during schedule monitoring. What does this mean in a construction context?

The project is 80% complete when 20% of the budget is spent
80% of schedule problems are caused by 20% of activities or subcontractors (Correct answer)
80% of project costs occur in the last 20% of activities
Only 20% of activities need to be tracked weekly

Correct answer: 80% of schedule problems are caused by 20% of activities or subcontractors

The Pareto principle (80/20 rule) suggests that most schedule problems stem from a small number of recurring root causes or parties.

Question 26: Under OSHA's heat illness prevention guidance, what is the recommended water intake for workers in hot outdoor environments?

About 1 cup (8 oz) of water every 15–20 minutes (Correct answer)
At least 1 gallon at the start of each shift
2 liters of water at lunch only

Failed insulated glass unit (IGU) seals allowing moisture between panes (Correct answer)
The windows are too energy-efficient for the climate

Correct answer: Failed insulated glass unit (IGU) seals allowing moisture between panes

Condensation between panes of an insulated glass unit indicates seal failure, which compromises the insulating gas fill and reduces the window's thermal performance.

Question 31: An unconditional lien waiver on final payment means the subcontractor:

Waives lien rights only after receiving full payment
Waives all lien rights immediately upon signing, regardless of whether payment is received (Correct answer)
Waives rights to future work only
Retains lien rights for 90 days after signing

Correct answer: Waives all lien rights immediately upon signing, regardless of whether payment is received

An unconditional waiver releases all lien rights immediately upon execution, so contractors must ensure payment is received before signing.

Question 32: Under the IRC, what is the minimum width required for a residential exit door (egress door)?

32 inches clear (Correct answer)

If a subcontractor files a mechanic's lien
If the winning bidder refuses to enter into the contract (Correct answer)
If the contractor fails to complete the work
If the project exceeds the original budget

Correct answer: If the winning bidder refuses to enter into the contract

A bid bond guarantees the owner that if the contractor wins the bid but declines to sign the contract, the bond will cover the difference between their bid and the next acceptable bid.

Question 34: What is 'subrogation' in the context of contractor insurance, and why do contracts often include a 'waiver of subrogation'?

Subrogation transfers policy limits to the project owner; a waiver restores them to the contractor
Subrogation allows an insurer to sue a third party after paying a claim; a waiver prevents the insurer from suing the other contracting party (Correct answer)
Subrogation is the process of adding additional insureds; a waiver removes that requirement
Subrogation is the insurer's right to cancel the policy; a waiver requires 30-day notice

Correct answer: Subrogation allows an insurer to sue a third party after paying a claim; a waiver prevents the insurer from suing the other contracting party

Subrogation lets an insurer recover from a liable third party after paying a claim; a waiver of subrogation prevents the insurer from pursuing the other party named in the contract.

Question 35: How should equipment be selected for specific tasks?

Question 56: How can cost overruns be prevented in a construction project?

By reducing the quality of materials.
By regularly tracking expenses and adjusting plans as needed. (Correct answer)
By delaying the project until more funds are available.
By working with fewer workers on-site.

Correct answer: By regularly tracking expenses and adjusting plans as needed.

Cost overruns occur when actual costs exceed budgeted costs. Regular tracking allows for early detection of potential overruns, enabling proactive adjustments to spending or project plans. This continuous monitoring and adaptation are crucial for maintaining financial control and preventing the project from exceeding its budget.

Question 57: A residential contractor is ethically obligated to disclose to a client:

Competitors' pricing on similar projects
Known defects or conditions that could materially affect the project cost or safety (Correct answer)
Proprietary subcontractor pricing
The contractor's overhead percentage

Correct answer: Known defects or conditions that could materially affect the project cost or safety

Ethical and legal obligations require contractors to disclose material facts about conditions that would affect the client's decision or the project's safety and cost.

Question 58: Under most residential construction contracts, a 'substantial completion' date is significant because it:

Starts the permit expiration countdown
Marks when the final payment is due in full
Allows the contractor to abandon the project legally
Triggers the warranty period and shifts remaining punch-list responsibility (Correct answer)

Correct answer: Triggers the warranty period and shifts remaining punch-list responsibility

Substantial completion means the project is usable for its intended purpose, triggering the warranty period and defining remaining punch-list obligations.

Question 59: In blueprint reading, what does the symbol 'ø' (phi) before a number indicate?
