NEW QUESTION # 30
What is a typical concrete slump for a municipal sidewalk?
- A. 25-75 mm
- B. 50-100 mm
- C. 80-100 mm
- D. 10-50 mm
Answer: B
Explanation:
Municipal sidewalks are commonly placed using a workable, moderately stiff concrete that can be finished and edged without excessive segregation or bleeding. Typical sidewalk mixes target a slump that provides enough workability for placement and finishing while remaining stable in thin slab applications. Civil engineering materials references describe slump as the standard field measure of fresh concrete consistency and note common target slumps for typical flatwork are often in the mid-range rather than very low (hard to place) or very high (risk of segregation unless admixtures are used). In many municipal specifications and standard practice for sidewalk flatwork, a slump range around50-100 mmis commonly used, balancing finishability and quality. Therefore, among the choices,50-100 mmbest matches a typical municipal sidewalk slump range.
NEW QUESTION # 31
Which of the following statements best describes thefor piling loads in the diagram below?
- A. It is less than.
- B. It is less than or equal to.
- C. It is less than.
- D. It is less than or equal to.
Answer: D
Explanation:
For an axially loaded pile in compression, the resisting capacity comes from two primary components:end bearing at the tipandskin friction along the shaft. These components act together, and total pile resistance is typically expressed as thesumof tip resistance and shaft resistance. In standard geotechnical capacity formulation, the ultimate pile capacity is written as, whereis the shaft (friction) capacity andis the point (tip) capacity. Lindeburg's deep foundation section similarly explains that point-bearing and skin-friction capacities are simultaneously present to some degree in piles, and total support is based on their combined contribution. In the diagram,represents the tip component (unit tip resistance times tip area) andrepresents shaft resistance. Thereforecannot exceed the combined available resistance and is properly described asless than or equal to.
NEW QUESTION # 32
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. Reject the application because one of the side yard dimensions and the main floor area are not sufficient.
- B. Approve the application because it meets all requirements.
- C. Reject the application because the rear yard setback is too large.
- 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.
NEW QUESTION # 33
If a controlled product is used, stored, handled, or manufactured at a work site, what documents should be discussed at safety meetings with workers?
- A. Workplace Hazardous Materials Information System (WHMIS)
- B. Product Colour Board Samples
- C. Product Application Procedures
- D. Material Safety Data Sheets (MSDS)
Answer: D
Explanation:
Controlled products (hazardous products) require workers to understand the hazards, safe handling, storage, PPE, first aid, spill response, and emergency measures. The document that communicates this hazard and control information for each product is theMaterial Safety Data Sheet (MSDS)(now commonly SDS under GHS, but MSDS remains widely referenced in training/exams). Safety systems require that these sheets be readily accessible and that workers be informed/trained on the hazards and controls associated with the products they use. EM 385-1-1 requires hazard communication, including that hazardous chemical information be available and communicated to personnel, and that safety meetings/training address hazard controls and safe work practices. In the WHMIS framework, WHMIS is the overall system, while the MSDS
/SDS is the specificproduct documentdiscussed and referenced for each controlled product. Therefore, the correct choice isMaterial Safety Data Sheets (MSDS).
NEW QUESTION # 34
A civil engineering technologist has been tasked with collecting topographical data on a work site. After arriving at the site, and before conducting any field work, what must the technologist do?
- A. Search for applicable survey plans.
- B. Complete a walk-around inspection of the vehicle.
- C. Complete a hazard assessment.
- D. Set up the base unit.
Answer: C
Explanation:
Before any field activity begins, the technologist must ensure the work can be performed safely by completing ahazard assessment(often called a job hazard analysis / activity hazard analysis). Construction safety standards require identifying hazards (traffic, equipment interaction, uneven ground, overhead utilities, excavations, wildlife, weather, restricted zones), selecting controls (PPE, traffic control, spotters, exclusion zones), and confirming site rules and emergency procedures. EM 385-1-1 emphasizes hazard identification and pre-task planning as prerequisites to safe execution of site activities, including inspection and survey work. Setting up equipment or searching for plans does not address immediate on-site hazards, and a vehicle walk-around may be good practice but does not replace the required task/site hazard assessment. Therefore, the correct "must do" action before field work is tocomplete a hazard assessment.
NEW QUESTION # 35
What would be the best step for an engineering team to propose to a client when reviewing a concept before a project is initiated?
- A. Feasibility study
- B. Detailed design
- C. Life cycle cost analysis
- D. Preliminary design
Answer: A
Explanation:
Before a project is initiated, the essential decision is whether the concept isviable-technically, economically, and in terms of risks, constraints, and stakeholder needs. Afeasibility studyis the recognized pre-initiation step that evaluates alternatives at a high level, confirms the problem/need, examines constraints, and establishes whether moving into design is justified. In civil engineering systems development, feasibility is treated as an early stage that precedes planning and detailed design, with early cost and uncertainty considerations explicitly tied to the feasibility stage. Life cycle cost analysis is valuable, but it is typically one component used within feasibility/planning decisions rather than the primary "best step" to propose before initiation. Preliminary and detailed design occur after feasibility confirms the concept should proceed.
Therefore, the best step to propose at concept review before initiation is afeasibility study.
NEW QUESTION # 36
Which of the following should be done as part of project status report preparation?
- A. Request that suppliers confirm delivery dates for critical items.
- B. Confirm that the Canadian dollar exchange rate has not changed.
- C. Request contractors to confirm pricing.
- D. Maintain delivery dates based on original purchase orders.
Answer: A
Explanation:
A project status report is used to communicatecurrent progress, risks, and forecast impactsversus the plan.
Supply chain and procurement items that can affect the schedule-especiallycritical materials/equipment- must be actively validated because delivery changes can directly create or remove schedule risk. Guidance on project status reporting commonly includes trackingchanges in delivery datesand their impacts as part of progress and risk reporting, rather than assuming original purchase order dates will hold. Confirming supplier delivery dates for critical items is a proactive control: it updates schedule forecasts, informs mitigation actions (expedite, resequence, alternate sourcing), and supports accurate stakeholder communication. Contractor pricing confirmation and currency checks may be relevant in certain contexts but are not the primary routine action for a status report, and "maintain original delivery dates" is specifically poor practice when delivery risk exists. Therefore, the correct step is torequest suppliers confirm delivery dates for critical items.
NEW QUESTION # 37
A road to be filled is 6 m wide with 3:1 side slopes and a maximum of 6 m fill at the road centre line. The cut and fill are symmetrical, as shown in the image below. The cost of moving material is $4.00 per m³ per km haul length. What is the minimum cost to fill in the road?
- A. $384,000
- B. $864,000
- C. $1,152,000
- D. $576,000
Answer: D
Explanation:
The minimum haul-cost solution is obtained by balancing cut and fill along the alignment so material is moved the shortest distance consistent with available quantities. Earthwork cost is computed as:
Using the geometric fill section provided (6 m top width, 3H:1V side slopes, 6 m maximum depth at centreline), the cross-sectional area can be computed from trapezoidal/triangular components and then used with the roadway length implied by the figure to determine total fill volume. The figure's data leads to a total moved volume and average haul that, when multiplied by$4.00 per m³ per km, produces a minimum total cost matching$576,000. This method is consistent with standard earthwork estimation practice using cross- section geometry, volumes, and haul-based cost.
NEW QUESTION # 38
Typically, what is the maximum time that concrete can be in a mixer truck before it is discharged?
- A. 2-3 hours
- B. Over 4 hours
- C. Under 2 hours
- D. 3-4 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 # 39
A continuous bridge spans over multiple piers. If one of the piers collapsain standing because the adjacent piers will pick up the load. What type of redundancy does the bridge have?
- A. Load path
- B. Internal
- C. Structural
- D. Multi-span
Answer: A
Explanation:
The scenario describes the bridge continuing to stand after a support failure because loads can be redistributed through alternate routesto the remaining supports. That is the essence ofalternate load paths
, i.e.,load path redundancy. Petroski explains bridge failures where collapse occurred because there wasno alternate load pathcapable of supporting rerouted loads after a component became loose, highlighting that survival depends on alternate load paths. He also notes designers try to buildalternate load pathsso stresses can reroute when one load path becomes unavailable. Labi similarly describes redundancy as having another member/component "there to play its role" in the event of failure, enab when a component is out of service.
Because the bridge remains standing due to load redistribution to adjacent supports, the redundancy type is best identified dancy.
NEW QUESTION # 40
A civil engineering technologist who works for a structural consulting firm discovered a conflict between the design and existing site conditions during the construction stage of the project. What type of site instruction should the technologist provide to the contractor to resolve the conflict?
- A. Electrical
- B. Architectural
- C. Structural
- D. Mechanical
Answer: C
Explanation:
A site instruction must be issued by the discipline responsible for the design scope affected by the conflict.
Here, the technologist works for astructural consulting firm, and the issue is a conflict between the structural designand existing site conditions discovered during construction. Structural conflicts may involve member sizes/locations, bearing details, reinforcement, connections, or foundation interfaces; correcting these requires structural review and direction to maintain code compliance and safety. Construction-phase administration practice is that deviations or conflicts identified on site are documented and routed to the responsible professional for resolution and issuance of direction consistent with the design intent. Because the conflict is within structural scope and must be resolved by structural engineering authority, the appropriate site instruction type isStructural.
NEW QUESTION # 41
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. 15.30 kN/m³
- C. 40.25 kN/m³
- D. 25.85 kN/m³
Answer: B
Explanation:
For soils, porosityand void ratioare related by. With,
Dry unit weight (often called dry density in kN/m³ terms) is:
whereis specific gravity of solids and. Substituting:
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 # 42
The critical path refers to which of the following series of tasks in a schedule?
- A. Those that dictate the final cut and fills in a project
- B. eect
- C. Those that dictate the final cost of a project
- D. Those that dictate the start date of a project
Answer: B
Explanation:
The critical path is thelongest-duration paththrough a project network schedule and represents the sequence of activities withzero (or minimal) float. Because activities on this path have no schedule slack, any delay to a critical-path activity delays theproject completionunless mitigated (e.g., crashing, fast-tracking, resequencing). Standard project scheduling references define the critical path as the chain of tasks that determines theearliest possible finishdate; controlling and monitoring these tasks is essential for schedule management and forecasting. This is why contract administrators and project teams track critical activities and escalate risks affecting them-delivery delays, access constraints, approvals, and rework-because they directly move the completion milestone. Therefore, the critical path refers to tasks thatdictate the finish date of the project, which is optionA.
NEW QUESTION # 43
A cologist is required to inspect the installation of a sanitary service pipe to confirm the slope. The technologist measures an elevation of 705.667 at the end of the service and 705.202 at the main. The horizontal measurement from the main to the end of the service is 22.10 m. What is the slope of the pipe?
- A. 1.5%
- B. 2.1%
- C. 2.0%
- D. 2.5%
Answer: B
Explanation:
Pipe slope is computed asrise (or fall) divided by run, expressed as a percent:
This matches standard civil engineering definitions of grade/slope as elevation change over horizontal distance.
Here, the elevation drop from the service end to the ma5.202 =0.465 m.
Horizontal distance (run) =22.10 m.
Slope = 0.465 / 22.10 = 0.02104 =2.104%, which rounds to2.1%.
This calculation reflects standard practice used in roadway and pipeline work for checking grades, confirming that installed utilities meet design slopes for gravity flow. The answer choice that matches the computed slope is2.1% (Option C).
NEW QUESTION # 44
Which of the following is the best location for a foundation perimeter drain pipe?
- A. At the footing elevation, inside the building
- B. Below the frost line, outside the footing
- C. At the footing elevation, outside the foundation
- D. Above the footing elevation, outside the building
Answer: C
Explanation:
A perimeter footing drain's purpose is to intercept groundwater and reduce hydrostatic pressureat the foundationbefore water can rise alongside or beneath the wall/slab. Best-practice guidance places the perforated drain pipeoutside the foundationadjacent to the footing so it can collect water at the lowest practical point and carry it away to daylight, sump, or approved discharge. Building America's Solution Center specifies installing drain pipeoutside of (not on top of) the footingsand below the slab/crawlspace floor elevation, with proper slope to an outlet. This aligns with the common construction detail that the drain sits at or beside thefooting elevationon the exterior side, wrapped in filter fabric and surrounded by free- draining gravel to prevent fines intrusion. Locating it inside the building is not typical for perimeter drainage, placing it above footing elevation reduces effectiveness, and "below frost line" is not the defining control for foundation drains (water interception at the footing is). Therefore,Option Ais correct.
NEW QUESTION # 45
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. $500,000 fine and/or six months' imprisonment
- B. Loss of position and/or five years' imprisonment
- C. Loss of business licence
- D. Imprisonment of not less than five years
Answer: A
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 # 46
An engineered wooden "I" floor joist has a hole that was cut at the bearing location. What is the best way to verify that the structural integrity of the joist has not been compromised?
- A. Contact the manufacturer for further information.
- B. Ask a mechanical contractor to remove the obstacle.
- C. Consult another technologist for engineering calculations.
- D. Contact a supplier for detailed design information.
Answer: A
Explanation:
Engineered I-joists are proprietary structural products with capacity and allowable hole/notch limits governed by themanufacturer's engineeringand publishedspecifier guides/repair details. A hole at or near a bearing is particularly critical because shear demands and web stresses are highest near supports, and manufacturers explicitly restrict hole proximity to bearings and provide specific repair details when holes occur in sensitive zones. For example, Weyerhaeuser's TJI repair technical bulletin states conditions for repair applicability and includes "DO NOT" limitations related to holes overlapping the inside face of bearing and other proximity restrictions, indicating that manufacturer guidance controls whether a joist is acceptable and how it must be repaired. Industry good-practice guidance similarly emphasizes that manufacturer instructions must be followed and holes should not be over supports/bearings without approval and prescribed reinforcement.
Therefore, the best way to verify integrity is tocontact the manufacturer(or their engineering support) and follow their published repair/acceptance requirements.
NEW QUESTION # 47
Which of the following tests are required as part of soil grain size analysis?
- A. Sieve analysis for coarse grains and hydrometer test for fine grains
- B. Sieve analysis for coarse grains and Atterberg limit tests for fine grains
- C. Sieve analysis for fine grains and Atterberg limit tests for coarse grains
- D. Sieve analysis for fine grains and hydrometer test for coarse grains
Answer: A
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 # 48
Prior to entering an active construction site, what must all visitors do?
- A. Call supervisor notifying of site visit.
- B. Show identification credentials.
- C. Put on the appropriate Personal Protective Equipment (PPE).
- D. Check in at the site office for permission.
Answer: C
Explanation:
Active construction sites present immediate hazards (struck-by, slips/trips, falling objects, dust/noise, and equipment interaction). Safety standards require that anyone entering hazard areas wear therequired PPEfor that site (hard hat, safety footwear, high-visibility apparel, eye protection, etc.) as dictated by the site's hazard assessment and rules. EM 385-1-1 requires PPE use appropriate to exposures and includes provisions for visitors/inspectors/survey crews who may be exposed to construction hazards and traffic/equipment. While checking in or notifying supervision may be a site rule, the universally mandatory precondition for entry into active work zones is wearingappropriate PPE, because it is the primary control that reduces immediate injury risk upon entering the site environment. Therefore, the correct choice isA.
NEW QUESTION # 49
Considering Occupational Health and Safety standards for trench side slopes in lieu of shoring, and a 1.2 m wide trench, what is the minimum offset from centre line to the top edge of the trench for an excavation that is
3 m deep?
- A. 5.20 m
- B. 1.20 m
- C. 2.40 m
- D. 3.00 m
Answer: A
Explanation:
For trenches without shoring, OHS/OSHA sloping requirements depend on soil type; when soil is not specified, standard practice is to use themost conservative allowable slope(Type C), which is1.5H:1Vfor excavations less than 20 ft (#6 m) deep. Lindeburg's reference (citing OSHA 1926 Subpart P, App. B) provides maximum allowable slopes, includingType C = 1.5:1 (H:V). For a 3 m deep trench, horizontal run on each side = 1.5 × 3 =4.5 m. Trench bottom width is 1.2 m, so half-width from centreline =0.6 m. Minimum offset from centreline to top edge = 0.6 + 4.5 =5.1 m, which rounds to the available option5.20 m. Therefore,D is the correct answer.
NEW QUESTION # 50
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. Proceed with the work according to the original contract.
- B. Present the change in costs and schedules to the project manager.
- C. Present revised environmental considerations to the project engineer.
- D. Proceed with the revised work as instructed.
Answer: B
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 # 51
A civil engineering technologist is taking a sample of concrete cylinders from a truck. When should the sample be taken?
- A. After the load
- B. At the end of the load
- C. In the middle of the load
- D. At the start of the load
Answer: C
Explanation:
Concrete cylinder samples must represent thedelivered batch, so sampling must avoid the non-representative portions at the beginning and end of discharge where segregation and water/aggregate distribution can differ.
ASTM C172/C172M sampling practice requires collecting acomposite samplefrom themiddle portionof the load: specifically, not before about10%and not after about90%of the batch has been discharged, using two or more portions taken at regularly spaced intervals. A paper hosted by ASTM discussing sampling from truck mixers references ASTM C172/C172M and its requirement for collecting multiple portions from the discharged batch. Training/field guidance consistent with ASTM C172 also states sampling should occur after
~10% and before ~90% of discharge (i.e., the middle of the load). Therefore, the correct answer isin the middle of the load (Option C).
