NEW QUESTION # 61
A civil engineering technologist is undertaking a final acceptance review of a subdivision. The technologist finds 35 m of deficient sidewalk and three hydrants which were not tested. As part of final acceptance, what should be done to ensure the hydrants get tested and the sidewalk is repaired?
- A. Write down that three hydrants were not tested, and that 35 m of sidewalk was deficient.
- B. Verbally communicate the locations of the hydrants and the sidewalk to the contractor.
- C. Write down the locations of the hydrants and the sidewalk and forward the deficiency list to the contractor.
- D. Request that the contractor write down the numbers and locations of the hydrants and the sidewalk.
Answer: C
Explanation:
Final acceptance requires that outstanding deficiencies be clearly identified and tracked to closure. Industry closeout practice uses adeficiency list (punch list/snag list)that itemizes nonconforming work and incomplete testing, and it is issued to the contractor so corrective actions can be completed before final acceptance is granted. A punch/deficiency list is specifically described as a document prepared near the end of a project that lists items that do not conform and must be rectified before completion certification. Best practice is to recordprecise locations(and identifiers like hydrant numbers), often with photos or plan references, to avoid ambiguity and ensure corrective work is verifiable. Verbal communication alone is not sufficiently traceable, and simply noting quantities without locations can lead to missed items and disputes.
Therefore, the correct action is todocument the locations and forward the deficiency list to the contractor so testing and repairs are completed and can be re-inspected for acceptance.
NEW QUESTION # 62
Who is responsible for establishing and maintaining a system that is compliant with the Occupational Health and Safety Act in a workplace?
- A. Prime contractor
- B. Sub-contractor
- C. General contractor
- D. Prime consultant
Answer: A
Explanation:
On multi-employer construction work sites, Occupational Health and Safety frameworks commonly assign a coordinating duty to aprime contractor(or equivalent controlling entity) to ensure site-wide compliance. This role exists because multiple employers and subcontractors may be present, and safety responsibilities must be coordinated through one accountable system. Alberta's OHS guidance, for example, states that the prime contractor mustestablish and maintain a system or process that ensures compliancewith the Occupational Health and Safety Act, Regulation, and Code at the work site, including coordinating the health and safety activities of all employers. This does not remove duties from subcontractors or workers, but it makes the prime contractor the party responsible for the overarching compliance system (e.g., site safety plan, coordination, hazard controls, cooperation processes). Therefore, the correct answer isPrime contractor.
NEW QUESTION # 63
A civil engineering technologist needs to recommend a foundation design for a commercial building. The borehole logs identify unsuitable bearing soils beneath the proposed floor elevation to a depth of 4 m and shallow bedrock at 5 m. Which of the following types of design should the technologist recommend?
- A. Slab on grade
- B. Friction piles
- C. End-bearing piles
- D. Strip footing
Answer: C
Explanation:
The subsurface profile indicates a weak/unsuitable bearing stratum extending several metres below the proposed founding level, withcompetent bedrock close beneath(shallow bedrock at about 5 m). Shallow foundations (slab-on-grade or strip footings) depend on adequate near-surface bearing capacity and acceptable settlement; with unsuitable soils to 4 m, shallow options would risk excessive settlement or bearing failure unless major ground improvement is performed. Where a strong bearing stratum such as bedrock is available at practical depth,end-bearing pilesare commonly selected to transfer structural loads through weak soils and seat on (or be socketed into) the competent stratum. Engineering references define end-bearing piles as piles driven/drilled to a firm layer/bedrock so that axial load is carried primarily inend bearingrather than relying on skin friction in weak compressible soils. With shallow bedrock, end-bearing piles provide a direct and reliable load path and reduce settlement uncertainty versus friction piles in poor soils.
NEW QUESTION # 64
A soil sample has a porosity of 40%, and the specific gravity of solids is 2.60. What would be the approximate value of dry density of the soil if the soil is completely saturated?
- A. 20.45 kN/m³
- B. 40.25 kN/m³
- C. 25.85 kN/m³
- D. 15.30 kN/m³
Answer: D
Explanation:
For soils, porosityand void ratioare related by. With,
Dry unit weight (often called dry density in kN/m³ terms) is:

Note that "completely saturated" affects thebulk/saturated unit weight, but thedryunit weight depends only on the solids content (via) and void structure (via), not on how much water occupies the voids. These phase- relationship calculations are standard in soil mechanics.
NEW QUESTION # 65
Which of the following records should be referenced during the preparation of a monthly progress payment certificate for a contractor?
- A. Contractor's packing slips
- B. Inspector's daily diary
- C. Inspector's daily progress record
- D. Contractor's weekly safety meeting record
Answer: C
Explanation:
Monthly progress payment certification is fundamentally based onverified quantities and percent complete for contract items installed in the field. Professional guidance on interim valuations emphasizes that periodic payments are established fromsite measurement/valuationof work completed, then certified by the contract administrator (or equivalent). That process requires a reliable field record of installed work-typically maintained daily by inspection staff-showing item-by-item progress, quantities, locations, and dates. Among the options, aninspector's daily progress recordis the document specifically intended to track completed work in a form that supports valuation, whereas a diary is less structured, packing slips only show deliveries (not acceptance/installation), and safety meeting records relate to OH&S rather than payment entitlement.
Therefore, the best supporting record for producing a progress payment certificate is theinspector's daily progress record, because it ties payment to measured/verified construction progress as required for interim certification practices.
NEW QUESTION # 66
A civil engineering technologist is to inspect control joint saw-cuts on a newly poured concrete slab. What saw cut depth would be typically specified?
- A. 1/4 of the total depth of the slab
- B. 2/3 of the total depth of the slab
- C. Total depth of the slab
- D. 1/2 of the total depth of the slab
Answer: A
Explanation:
Control joints (contraction joints) are intended to create aplane of weaknessso shrinkage cracking forms at the joint rather than randomly. For saw-cut control joints, typical practice is to cut deep enough to be effective but not so deep that it compromises slab capacity or cuts reinforcement. Civil engineering materials references describe contraction/control joints as used to control cracking and indicate that the joint must form an intentional weakened section. A common "rule of thumb" for saw-cut depth is approximatelyone-quarter of the slab thicknessfor conventional slabs-on-grade (deeper cuts may be specified for thicker slabs or special conditions, but 1/4 is the typical baseline). This depth is generally sufficient to initiate cracking at the joint line while preserving structural integrity of the slab. Therefore, the typical specified saw cut depth is1/4 of the total slab depth.
NEW QUESTION # 67
A civil engineering technologist works for a contractor. An engineer notifies him that the depth of concrete pilings needs to be increased. What is the first thing the civil engineering technologist should do?
- A. Present the change in costs and schedules to the project manager.
- B. Proceed with the revised work as instructed.
- C. Present revised environmental considerations to the project engineer.
- D. Proceed with the work according to the original contract.
Answer: A
Explanation:
Increasing pile depth is a scope change that affectsquantity of work, time, equipment effort, and cost. In contract-based construction, changes are handled throughformal change mechanisms(variations/change orders) that adjust scope, schedule, resources, and compensation as part of the contract documents. Civil engineering construction references define a change order as a formal document used to modify the contractual agreement and note that change orders may be established for changes in schedule, resource allocation, scope, and compensation. Because the technologist works for the contractor, the immediate project- control step is to ensure the project manager is aware of the impact so that pricing, schedule updates, and contractual change procedures can be initiated before proceeding. Simply proceeding (original or revised) without addressing cost/schedule implications risks uncompensated work and unmanaged schedule impacts.
Therefore, the first action is topresent the change in costs and schedules to the project manager.
NEW QUESTION # 68
Which of the following is employee's responsibility in regard to PPE?
- A. Select PPE appropriate for the hazard.
- B. Inspect PPE before use.
- C. Receive training on the correct use of PPE.
- D. Ensure PPE is maintained correctly between uses.
Answer: B
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 # 69
A civil engineering technologist asked an engineer in training (EIT) to write a deficiency report. After a few revisions, the report is still disorganized and has errors. What would be an appropriate action to take for the technologist?
- A. Assist the EIT in re-writing the report.
- B. Report the EIT to the supervisor and recommend training.
- C. Complete the document on behalf of the EIT.
- D. Explain to the EIT the importance of meeting deadlines.
Answer: A
Explanation:
Deficiency reports are project records that must be clear, accurate, and professionally defensible because they can affect acceptance, payment, corrective work, and potential disputes. When an EIT's report remains disorganized after multiple revisions, the appropriate next step is active coaching to bring the document to an acceptable standard while building the EIT's competence. Civil engineering practice emphasizes truthful, objective professional reporting founded on adequate knowledge and careful documentation. In construction- phase administration, effective project performance depends on frequent communication and monitoring, and the quality of project documentation directly supports decisions and follow-up actions. Assisting the EIT in rewriting preserves accountability (the EIT learns and improves), strengthens the quality of the final record, and supports timely resolution of deficiencies without escalating prematurely. Simply finishing the document on their behalf removes the learning opportunity and can mask competency gaps; reporting them immediately to a supervisor is disproportionate when a direct corrective mentorship step is available. Therefore, the technologist shouldassist the EIT in re-writing the report.
NEW QUESTION # 70
A contractor is using a compactor on a hot and dry day and quickly compacts a dry 300 mm thickness of sub- base without adding water. The soil is near optimum moisture. A civil engineering technologist completes compaction tests and finds that specifications have not been achieved. What should be done?
- A. Add water and re-compact.
- B. Strip the sub-base down to sub-grade and import new material.
- C. Re-compact and retest the soil.
- D. Continue with base placement and compaction.
Answer: C
Explanation:
Compaction acceptance is based on achieving specifiedin-place dry density(relative compaction) at an acceptable moisture range. If the material is alreadynear optimum moisture, failure to meet density typically points toinsufficient compactive effort,inadequate number of passes,improper equipment, orexcessive lift thickness(300 mm can be too thick for some sub-base and equipment combinations). Standard compaction theory shows that near OMC, soils should densify efficiently; if density is still low, the first corrective action is toincrease compactive effortand verify results with another field density test. Adding water when already near OMC may push moisture above optimum and can reduce achievable dry density.
Continuing with base placement would lock in a nonconforming layer, and stripping/importing new material is a last-resort remedy after reasonable rework attempts. Therefore, the best immediate corrective action is to re-compact and retest, adjusting lift thickness/passes as needed to meet specification.
NEW QUESTION # 71
What material property is measured by a sieve analysis?
- A. Angularity
- B. Mass
- C. Gradation
- D. Moisture density
Answer: C
Explanation:
Sieve analysis is the standard laboratory procedure used to determine theparticle size distributionof granular materials by passing a representative dry sample through a stack of sieves with progressively smaller openings and measuring the mass retained on each sieve. The result is a gradation curve (percent passing vs.
sieve size) that characterizes whether the material is well-graded, poorly graded, or gap graded, and it is foundational for specifying aggregates for concrete, asphalt, base course, and filters. Civil engineering materials references identify sieve analysis as the test used to determinegradationand classify soils
/aggregates by size ranges. Angularity is a shape characteristic not measured by sieve analysis; moisture- density relates to compaction testing; and "mass" is a measured quantity in the procedure, but the material property being determined is thegradation (particle size distribution). Therefore, the correct answer isD.
NEW QUESTION # 72
What personal protective equipment is most important when surveying near active traffic?
- A. Leather gloves
- B. Hearing protection
- C. High-visibility vest
- D. Safety glasses
Answer: C
Explanation:
Surveying near live traffic exposes workers to struck-by hazards from vehicles and mobile equipment. Safety requirements for such environments prioritize making personnel conspicuous to drivers and equipment operators. The USACE Safety and Health Requirements Manual (EM 385-1-1) explicitly requireshigh- visibility apparel(minimum ANSI/ISEA Class 2) for workers such assurvey crews and inspectorswhen exposed to vehicular or equipment traffic, limited visibility, reduced visibility conditions, or when working close to traffic without protective barriers. This directly matches the scenario (surveying near active traffic) and identifies high-visibility apparel as the key PPE to reduce struck-by risk by improving detection and recognition of workers. While eye, hand, and hearing protection may be needed depending on hazards, the most critical single PPE item for traffic-adjacent surveying is thehigh-visibility vest/apparelrequired for worker visibility and traffic safety controls.
NEW QUESTION # 73
The invert elevation of a sanitary sewer line is 98.150 m, the pipe thickness is 12 mm and its outside diameter is 600 mm. Using the image below, what is the crown elevatf m
- A. 101.488 m
- B. 101.500 m
- C. 101,238 m
- D. 101.250 m
Answer: C
Explanation:
Invert elevation is the elevation of theinside bottomof the pipe. With outside diameterm and wall thicknessm, the inside diameter ism. The vertical distance from invert (inside bottom) to theoutside top of pipeism, giving the outside top-of-pipe elevation:m. The section detail in the provided image shows the vertical cover from top of pipe to top of asphaltas approximately2.476 m(dimensioned in the road section). Adding this cover gives the road crown elevation:m, matching optionA. This uses standard civil geometry conversions between invert, pipe dimensions, and surface elevations used in utility/roadway inspection and verification.
NEW QUESTION # 74
For granular material, what is the typical optimum moisture content for dry densities ranging from 2100 kg/m³ to 2200 kg/m³?
- A. 8-15%
- B. 21-25%
- C. 4-7%
- D. 16-20%
Answer: C
Explanation:
Theoptimum moisture content (OMC)is the moisture content at which a soil achievesmaximum dry density for a given compactive effort on the Proctor curve. Granular materials (sands/gravels with low plastic fines) typically requirerelatively low moistureto reach peak density because their structure densifies primarily by particle rearrangement; only a small amount of water is needed to lubricate contacts and aid compaction.
Training/compaction manuals define OMC as the peak of the moisture-density relationship and highlight that coarse-grained materials generally peak at lower moisture than fine-grained soils. A maximum dry density range of about2100-2200 kg/m³(#2.10-2.20 Mg/m³) is consistent with well-compacted granular base
/subbase, which commonly has an OMC in thesingle-digit percentrange. Therefore, the typical OMC range that best matches granular materials at these densities is4-7%.
NEW QUESTION # 75
Which of the following isnota type of structural foundation system used to hold the weight of a building?
- A. Grade beam and piles
- B. Structural slab-on-grade
- C. Concrete formwork
- D. Wall and strip footings
Answer: C
Explanation:
A "foundation system" is a permanent structural/geotechnical arrangement that transfers building loads to the supporting ground (e.g., shallow foundations like strip/spread footings or slabs-on-grade, and deep foundations like piles with grade beams). Options A, B, and D are all recognized foundation systems: pile
/grade beam systems are deep foundation solutions; wall and strip footings are shallow continuous foundations; and structural slabs-on-grade are shallow systems that distribute loads to prepared subgrade. By contrast,concrete formworkis atemporary construction means-the molds, supports, and bracing used to shape and support fresh concrete until it gains strength. Formwork is not part of the final load path once removed, and it does not function as a load-transfer system into soil/rock. Therefore, among the choices, the item that is not a foundation system isconcrete formwork.
NEW QUESTION # 76
Typically, what is the maximum time that concrete can be in a mixer truck before it is discharged?
- A. Over 4 hours
- B. 3-4 hours
- C. Under 2 hours
- D. 2-3 hours
Answer: C
Explanation:
Ready-mixed concrete must be placed and discharged within a controlled time window to ensure workability and performance are not compromised by slump loss, early setting, or excess mixing. Historically, widely used industry standards and guidance for ready-mixed concrete commonly referenced a90-minutedischarge limit (or equivalent revolutions limit) from the start of mixing to completion of discharge, unless otherwise specified by project requirements. A 90-minute rule falls clearly within "under 2 hours," making that option the best match to typical industry practice reflected in technical discussion and standards commentary. While some newer editions of ASTM C94 allow the purchaser and producer to establish a project-specific limit, the traditional default guidance that many practitioners associate with mixer-truck discharge remains well under two hours. Therefore, the correct selection among the provided options isUnder 2 hours.
NEW QUESTION # 77
What substance is used to calibrate a concrete air pressure meter?
- A. Water
- B. Concrete
- C. Oil
- D. Air
Answer: A
Explanation:
A pressure air meter (used to measure air content of fresh concrete) must be calibrated by verifying thevolume of the measuring bowl and theaccuracy of the graduated neck/markings. This is done usingwaterbecause water volume can be measured accurately and used to check the meter's indicated graduations (air content scale) by filling the assembled unit to known levels. InExperiment Design for Civil Engineering, the calibration procedure directs filling the assembled air meterwith waterto the highest graduation mark and adding water in known increments to verify that the graduations are accurate throughout the range. The same source references using water to establish the mass/density) and to check calibration cups and neck readings.
Therefore, the substance used to calibrate the air pres*, makingOption Bcorrect.
NEW QUESTION # 78
A site inspection reveals a beam that does not conform to Issued for Construction (IFC) drawings. What should be done?
- A. Document the issue and notify the engineer
- B. Document the issue and file it
- C. Verify engineering calculations on IFC drawings
- D. Remove the beam and notify the contractor
Answer: A
Explanation:
When inspection identifies nonconforming work relative to IFC drawings, the inspector/technologist's role is todocumentthe condition (location, description, measurements, photos) andnotify the responsible design professional/engineerfor disposition. This aligns with formal quality control/assurance processes: field staff identify and record deviations; the engineer evaluates structural implications and issues written instructions (accept as-is, remediate, redesign, or replace). Acting unilaterally to remove a beam (option B) exceeds typical authority and may create safety and contractual issues. Simply filing without notification (C) fails to address a potentially serious structural deficiency. Rechecking the IFC calculations (D) is not the immediate construction control action; the priority is to initiate an engineering review of the nonconformance. Civil engineering project practice stresses maintaining complete inspection records and communicating significant issues through appropriate channels for corrective action. Therefore, the correct action isdocument the issue and notify the engineer.
NEW QUESTION # 79
Whatto determine the compressive strength of concrete?
- A. Cylinder test
- B. Slump test
- C. Air test
- D. Sieve test
Answer: A
NEW QUESTION # 80
When calculating the total cost for a multi-year project, which of the following parameters should be considered?
- A. Current material delivery times
- B. Escalation cost
- C. Cost of material
- D. Alternate material availability
Answer: B
Explanation:
Multi-year projects must account for the fact that costs do not remain constant over time; labor, materials, equipment, and subcontract pricing can increase due to inflation and market conditions. Therefore, budgets for longer-duration projects include anescalation estimateto reflect anticipated cost growth over the project timeline. Project management budgeting references explicitly list escalation estimate as a standard budget line item (separate from contingency), recognizing that future-year expenditures need escalation adjustments to be realistic. Civil engineering systems cost analysis also discusses cost escalation patterns in large projects and identifies "cost escalation" as a key phenomenon affecting final cost compared with earlier estimates. While material cost, availability, and delivery times matter for procurement and risk, the parameter that specifically addresses multi-year total-cost realism isescalation cost.
NEW QUESTION # 81
Which of the following items appears on a record drawing?
- A. Changes from the original construction documents
- B. Quantities for tender
- C. Safety meeting minutes
- D. Initial project estimates
Answer: A
Explanation:
Record drawings (often associated with "as-built" documentation) are the finalized drawing set that reflects theconstructed conditionof the project. Their core purpose is to capture and preservefield changesand deviations from the original issued construction documents so that the owner and future stakeholders have an accurate technical record for operations, maintenance, and future modifications. During construction, changes can occur due to site conflicts, approved substitutions, design clarifications, and coordination between trades.
Those modifications must be consolidated so the final drawings match what was actually installed. In contrast, initial estimates and tender quantities belong to procurement and cost management documentation, while safety meeting minutes belong to safety administration records. A record drawing therefore focuses on revisions to the original design-locations, sizes, elevations, and details that differ from the original plan set-so that the final documents represent the "as-constructed" asset. This is why "changes from the original construction documents" is the defining item that appears on record drawings.
NEW QUESTION # 82
According to Occupational Health and Safety legislation, who is responsible for safety in the workplace?
- A. Supervisors and employers
- B. Employees and employers
- C. Employees and supervisors
- D. Employees
Answer: B
Explanation:
Workplace safety is ashared responsibilityframework: employers must establish systems, provide training, supervision, and hazard controls, while employees must follow procedures, use PPE, and work safely. Safety manuals used on construction projects reflect this shared-duty approach by requiring employer-provided programs and controls and worker compliance and participation. For example, project safety planning requires hazard identification, training, PPE compliance, and exposure monitoring processes-elements that depend on both management implementation and worker adherence. In multi-employer construction environments, prime contractors coordinate compliance, but this does not eliminate the duties of employers and workers; rather, responsibilities are distributed across roles. Therefore, among the options, the most accurate statement aligned with typical OHS legislative principles is thatemployees and employersare responsible for safety in the workplace.
NEW QUESTION # 83
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. Approve the application because it meets all requirements.
- B. Reject the application because the rear yard setback is too large.
- C. Reject the application because one of the side yard dimensions and the main floor area are not sufficient.
- D. Refer the application to Council because it does not meet the requirements.
Answer: D
Explanation:
The bylaw excerpt establishes mandatory requirements (one family, minimum 120 m² floor area, and minimum setbacks) and then provides the required administrative action in Section 3.4:any application that does not fulfill the above requirements shall be referred to Council. The correct decision is therefore governed directly by the regulatory text: when any requirement is not met, the prescribed next step is referral rather than approval. Option C matches the bylaw's stated process exactly by directing the application to Council due to noncompliance. Options B and D propose outright rejection reasons that the excerpt does not authorize as the required action; the excerpt explicitly states "referred to Council" for noncompliant applications. Option A is only valid when all requirements are met. Accordingly, the correct response isrefer to Council.
