NEW QUESTION # 28
Which of the following tests are required as part of soil grain size analysis?
- A. Sieve analysis for fine grains and Atterberg limit tests for coarse grains
- B. Sieve analysis for fine grains and hydrometer test for coarse grains
- C. Sieve analysis for coarse grains and Atterberg limit tests for fine grains
- D. Sieve analysis for coarse grains and hydrometer test for fine grains
Answer: D
Explanation:
Soilgrain size analysisdetermines the particle-size distribution across coarse and fine fractions. Coarse particles (sand and gravel) are sized bysieve analysis, where the sample is passed through a stack of sieves and the mass retained on each sieve is measured to build the gradation curve. Fine particles (silt and clay) are too small for practical sieving and are therefore sized usingsedimentation methods, most commonly the hydrometer test, which infers particle sizes from settling velocity in a suspension. This combined approach (sieve for coarse, hydrometer for fines) is standard in civil geotechnical testing programs because it produces a continuous particle-size distribution needed for soil classification and engineering assessment. Atterberg limits (LL/PL) areconsistency/plasticitytests for fine-grained soils-not grain size tests-so they are not the required fine-fraction method for grain-size analysis. Therefore, the correct combination for grain size analysis issieve analysis for coarse grains and hydrometer test for fine grains.
NEW QUESTION # 29
Which factor aggravates a freeze-thaw cycle and contributes to asphalt pavement deterioration?
- A. Maximum aggregate size in the sub-base
- B. Compaction during construction
- C. Poor drainage
- D. Type of oil in the asphalt
Answer: C
Explanation:
Freeze-thaw pavement damage is driven bywater presencein cracks/voids and repeated freezing and thawing. When water enters pavement cracks and freezes, it expands and worsens cracking; repeated cycles promote disintegration and pothole formation. Poor drainage increases theavailability and residence time of waterin the pavement structure, so more water can infiltrate cracks and remain trapped in layers, intensifying freeze-thaw action and accelerating deterioration. This mechanism is consistent with documented observations that water entering cracks, freezing, and thawing expands cracks and breaks bonding, leading to potholes and rapid local deterioration under traffic. Therefore, among the given choices, the factor that most directly aggravates freeze-thaw cycles and contributes to asphalt deterioration ispoor drainage.
NEW QUESTION # 30
What must an employer do if an employee could be exposed to hazardous materials on a work site?
- A. Remove hazardous materials from the work site prior to starting work.
- B. Provide hazmat suits for employees' use.
- C. Establish procedures to minimize employee exposure.
- D. Conduct air sample testing prior to starting work.
Answer: C
Explanation:
When hazardous materials may be present, employers must implement ahazard control program: identify hazards, communicate them, and apply controls (engineering, administrative, PPE) to prevent or minimize exposures. The USACE Safety and Health Requirements Manual (EM 385-1-1) requires employers to establish and enforce safety procedures and controls for hazardous substances, including hazard communication and safe work practices, rather than relying on a single measure like removing all hazards or issuing hazmat suits in every case. Air sampling may be necessary for certain exposures, but it is not universally required "prior to starting work" in every scenario; similarly, removing all hazardous materials is not always feasible. Therefore, the required primary action is toestablish procedures to minimize employee exposure(controls, training, and safe handling requirements).
NEW QUESTION # 31
Which of the following are the most effective ways to communicate with ot contract?
- A. Calling clients or co-workers at home
- B. Memos, instant messages, and video conferences
- C. Leaving a message with a receptionist
- D. Email, memos, and meetings
Answer: D
Explanation:
Construction contract communication must bedocumented, clear, and traceableto support coordination, decisions, and potential claims management. Civil engineering project administration emphasizes collecting and maintaining accurate information and records to manage issues and provide defensible documentation.
Labi notes the importance of rigorous follow-up processes and maintaining accurate, up-to-date data for claims management and project feedback. Email and memos provide written records that can be filed and referenced, while meetings (with minutes) enable alignment amonlution of coordination items. Leaving messages with receptionists or contacting people at home is unreliable and not professionally appropriate.
Instant messages/video conferences can be useful, but unless they are formally recorded and controlled, they may not provide the same contractual traceability as emails/memos and structured meetings. Therefore, the most effective methods listed areemail, memos, and meetings.
NEW QUESTION # 32
A project manager is aware of a faulty fall protection railing. The safety issue is reported but not remedied or documented. In the event of an incident, what is the maximum penalty for the first offence under the Occupational Health and Safety Act?
- A. Imprisonment of not less than five years
- B. $500,000 fine and/or six months' imprisonment
- C. Loss of position and/or five years' imprisonment
- D. Loss of business licence
Answer: B
Explanation:
Under Alberta's Occupational Health and Safety (OHS) legislation, enforcement includes significant penalties for contraventions, especially where hazards like fall protection are involved and an incident occurs. Alberta's official guidance on convictions under OHS legislation states that for afirst offenceunder the OHS Act, fines can beup to $500,000and/orup to 6 months in prisonper violation (with additional daily fines possible if the offence continues). This directly matches the option describing a$500,000 fine and/or six months' imprisonment. The other options (loss of business licence, mandatory five-year imprisonment, etc.) are not the stated maximum first-offence penalty in the cited OHS information. Therefore, the correct maximum penalty for the first offence isOption C.
NEW QUESTION # 33
A concrete mix is onsite and at its specified slump of 80 mm. The pour requires a slump of 200 mm. The concrete onsite meets all other requirements. What action should be taken?
- A. Order a different concrete mix
- B. Add water to the concrete onsite
- C. Add low-range water reducer to the concrete onsite
- D. Add high-range water reducer to the concrete onsite
Answer: D
Explanation:
Increasing slump from80 mm to 200 mmis a large jump in workability. Adding water would increase slump but typically raises the water-cement ratio, which can reduce strength and durability and increase cracking risk unless it remains within permitted limits and is authorized. Industry guidance on jobsite water addition recommends consideringwater-reducing admixtures / superplasticizersas the preferred alternative for increasing slump while maintaining concrete performance, provided segregation is avoided and proper mixing is performed.
Ahigh-range water reducer (HRWR), also called asuperplasticizer, is specifically intended to produce a major increase in slump/flow at essentially the same water content, achieving very high workability concrete for placement. Low-range water reducers typically do not provide such a large slump increase. Therefore, the correct action is toadd a high-range water reducerto achieve the required 200 mm slump without compromising the designed water-cement ratio and associated properties.
NEW QUESTION # 34
Which of the following is employee's responsibility in regard to PPE?
- A. Ensure PPE is maintained correctly between uses.
- B. Receive training on the correct use of PPE.
- C. Select PPE appropriate for the hazard.
- D. Inspect PPE before use.
Answer: D
Explanation:
Employee responsibilities for PPE typically includeusing PPE as required and checking it is serviceable before use, then reporting defects. Employer responsibilities generally include hazard assessment, selecting
/providing appropriate PPE, ensuring training, and maintaining a program. EM 385-1-1 reflects this division of duties: it requires PPE to be used to control exposures and establishes training requirements covering key aspects of PPE, includinginspection/testingand proper care. Practical safety guidance for workers also states that employees shouldcheck PPE for faults before useand report issues. Among the optionsuployee duty that is broadly applicable across PPE types and aligns with standard safety systems: workers verify their equipment is not damaged, fits correctly, and is suitable for the task before entering the hazard area.
Therefore, the correct answer isA.
NEW QUESTION # 35
What is the purpose of a spiral curve in highway design?
- A. To slow traffic when the minimum sight distance cannot be achieved
- B. To slow traffic when the superelevation of the lane is greater than 5%
- C. To transition onto a vertical curve
- D. To transition into a circular curve
Answer: D
Explanation:
Aspiral (transition) curveis used in horizontal alignment to provide a gradual change in curvature from a tangent (infinite radius) to a circular curve (constant radius). AASHTO explains that spiral transition curves simulate the natural turning path of a vehicle and allow lateral acceleration (and side friction demand) to increase/decrease gradually as drivers enter/exit the circular curve, improving comfort and reducing encroachment. AASHTO also notes that the transition curve length provides a suitable location to develop superelevation runoffsmoothly from normal crown to full superelevation. These functions are specifically about transitioning into (and out of) the circular curve, not slowing traffic or transitioning vertical alignment.
Therefore, the purpose of a spiral curve isto transition into a circular curvewhile providing a smooth geometric and superelevation transition for drivers.
NEW QUESTION # 36
A developer is planning to build an office building on a 4-acre parcel of land. Which of the following documents will tell the developer how much fill to bring to the site to make it level?
- A. Topographic survey plan
- B. Foundation plan
- C. Architectural plan
- D. Real property report
Answer: A
Explanation:
Determining how much fill is needed to level a site requires knowing theexisting ground elevationsacross the parcel and comparing them to a proposed target grade plane/surface. Atopographic survey planprovides the required elevation information (spot elevations, contours, breaklines, and surface features) from which earthwork quantities (cut/fill volumes) are computed. Foundation and architectural plans generally show building geometry and design intent, not full-site existing elevations. A real property report focuses on legal boundary information and improvements relative to property lines, not the detailed elevation grid needed for volume calculations. Civil engineering practice uses topographic survey data as the basis for grading design and earthwork estimation, including calculating volumes via grids or cross-sections.
NEW QUESTION # 37
What is a silt fence used for?
- A. To mark the construction limits of the project
- B. To prevent soil from moving through the site due to erosion
- C. To prevent water from moving through the site
- D. To prevent the public from accessing the construction site
Answer: B
Explanation:
A silt fence is an erosion and sediment control measure intended toretain sedimentcarried by runoff, reducing offsite sedimentation. Lindeburg describes temporary silt fences as measures using posts and filter cloth (e.g., filter fabric) placed on the upstream side toretain suspended silt particles in runoff water. This purpose is to reducesoil movement(sediment transport) caused by erosion processes during construction, especially oalong drainage paths where siltation is expected. The fence does not "stop water" (runoff still passes through while sediment is filtered), is not primarily a site limit marker, and is not an access control barrier for the public. Therefore, the correct statement is that a silt fence is usedto prevent soil from moving through the site due to erosion.
NEW QUESTION # 38
A gas fireplace has been installed by the general contractor's sub-trade. After numerous repair attempts, it is still not operating properly. How should the owner correct the problem?
- A. Ask the sub-trade to review and correct the entire installation.
- B. Engage a new mechanical contractor for repairs and back-charge the general contractor.
- C. Ask the general contractor to review and correct the installation.
- D. Contact the fireplace manufacturer for assistance.
Answer: C
Explanation:
Under standard construction contracting practice, thegeneral contractor (prime contractor)is responsible for the overall delivery of the work, including coordination and quality of subcontractors' work and correction of deficiencies that fall under the contract's quality obligations and warranty requirements. Warranties are specifically described as requiring the contractor to repair or replace deficient work within a specified period at the contractor's expense. Since the subcontractor is contractually accountable to the general contractor (not directly to the owner in a typical arrangement), the owner's most effective and proper route is to require the general contractorto address the deficiency, manage the subcontractor, and ensure the system performs as required. Escalating directly to a new contractor and back-charging can be possible, but it is typically a later remedy after formal notice and contract procedures. Contacting the manufacturer may help diagnose, but it does not replace contractual responsibility for correction. Therefore, the correct action is toask the general contractor to review and correct the installation.
NEW QUESTION # 39
EXCERPT FROM MUNICIPAL BYLAW 1234 - ZONING
Section 3: Single family zone
3.1 All dwellings shall house one family.
3.2 All dwellings shall have a minimum main floor area of 120 m².
3.3 All dwellings shall be constructed a minimum of 10.0 m from the front property line, 15.0 m from the rear property line, and 1.5 m from the side property lines.
3.4 An application that does not fulfill the above requirements shall be referred to Council.
- A. Refer the application to Council because it does not meet the requirements.
- B. Approve the application because it meets all requirements.
- C. Reject the application because the rear yard setback is too large.
- D. Reject the application because one of the side yard dimensions and the main floor area are not sufficient.
Answer: A
Explanation:
This question is resolved by applying the bylaw excerpt exactly as written. Sections 3.1 to 3.3 define the zoning requirements, and Section 3.4 dictates the decision rule:if an application does not fulfill the requirements, it must be referred to Council. Therefore, the correct action for any noncompliant application is referral to Council, not approval and not outright rejection under the terms provided in the excerpt. Option C is the only option that aligns with the bylaw's stated administrative process. Option A applies only when all requirements are satisfied. Options B and D give rejection rationales, but the excerpt does not state that the application is rejected automatically; instead, it specifies referral to Council. Hence, the correct answer isC.
NEW QUESTION # 40
Which of the following correctly indicates the information that must be provided on a site plan?
- A. Finish grades, setback distances, and the legal description
- B. Finish grades and setback distances
- C. Finish grades and the legal description
- D. The legal description
Answer: A
Explanation:
A site plan is a permitting and construction control document that must allow reviewers and builders to verify property identification,zoning compliance, andgrading/drainage intent. Thelegal descriptionidentifies the parcel unambiguously for land/title and municipal records.Setback distancesare required to demonstrate compliance with zoning bylaws (front/rear/side yard requirements, easements, and building placement).Finish gradesare required to show how the site will drain, how elevations relate to adjacent properties and infrastructure, and to support earthworks and servicing design. Together, these three items are the common minimum "must-have" information set: legal description (what lot), setbacks (where you can build), and finish grades (how the site will be shaped and drained). Civil engineering site development practice treats these as core content of a site plan because they support approvals and constructability.
NEW QUESTION # 41
A geotechnical report indicates the presence of a peat layer in several boreholes. The peat layer ranges in thickness from 450 mm to 1200 mm and is found at a depth of 1.5 m below the existing grade. How should this be addressed in the project specifications that are being prepared?
- A. Advise the bidders that the peat layer is present
- B. Determine the bearing strength of the peat material and include this information in the specifications
- C. Include a clause stating that the peat should be removed from the area
- D. Propose a method of stabilizing the peat layer in the specifications
Answer: C
Explanation:
Peat is a highly organic soil withvery high compressibility, low shear strength, and problematic long-term settlement behavior. If peat is present within the stress influence zone of foundations or slabs (here, relatively shallow at ~1.5 m depth), typical construction practice is to treat it asunsuitable materialunless a designed ground-improvement solution is explicitly adopted. When the geotechnical investigation identifies such material in advance, the project specifications should convert that known condition into aclear scope requirementso pricing and execution are defined-commonly by requiringover-excavation/removal and replacement with suitable compacted fillin affected areas, subject to engineer direction and limits. USACE guidance for earthworks/foundations explicitly states thatsoft or organic spots in the foundation should be removed and replaced with compacted materialas part of foundation preparation.
Therefore, the most appropriate way to address the identified peat in the specifications is toinclude a clause requiring peat removal(and replacement per spec), which isOption C.
NEW QUESTION # 42
Concrete thrust block measures 0.6 m by X m in the diagram. If the test pressure is 1034 kPa and the bearing pressure of the soil is 239 kPa, what is the minimum value of X?
- A. 0.030 m
- B. 0.304 m
- C. 0.136 m
- D. 0.226 m
Answer: D
Explanation:
Thrust blocks resist unbalanced pressure forces at fittings (tees/bends/caps) by mobilizing bearing against undisturbed soil. The basic thrust relationship isForce = Pressure × Areaacting on the pipe's internal cross- sectional area. DIPRA's thrust restraint guide states that internal hydrostatic pressure acts on any plane with a force equal toP times A.
From the diagram, the pipe diameter is0.200 m, so pipe area. Thrust. Required soil bearing area. Given block face area, solve. Thus the minimumis0.226 m (Option C).
NEW QUESTION # 43
What type of survey stake is shown in the image below?
- A. A centreline stake
- B. A grade stake
- C. A benchmark stake
- D. A slope stake
Answer: A
Explanation:
Acentreline stakeis used to mark the roadway/control alignment in the field, typically at stations, and is identified by centreline-related notation rather than cut/fill or slope-to-daylight information. In the image, the stake is marked in a way consistent withcentreline stationing/control(as opposed to slope stakes, which typically include slope ratio, offset, and cut/fill to finished grade, or benchmark stakes, which serve as elevation control points). Standard construction staking guidance notes that stake markings communicate what line is being staked (e.g.,CL) and its relationship to stationing and control.
Because the stake is presented as a control point for alignment (centreline) rather than a grade/slope instruction, it is best classified as acentreline stake.
