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.
正解：D
解説：
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.

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?
正解：B
解説：
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.

What is the main reason for taking handwritten notes while surveying?
正解：A
解説：
Survey work depends on traceable, reproducible observations. Handwritten field notes (field book entries, sketches, stationing, and benchmark ties) function as theprimary recordof what was measured, under what conditions, and how control was established. Lindeburg describes that elevations of temporary benchmarks are generally found infield notesand local official filings, reflecting that field notes are treated as an enduring record used later for computations, verification, and re-establishment of control. This is why good surveying practice emphasizes complete notes, clear sketches, and unambiguous identification of points-so results can be checked, recalculated, and defended long after the crew leaves site. While survey data supports mapping and may indirectly support disputes, the fundamental purpose of handwritten notes is to create apermanent, auditable recordof survey results and control ties.
質問 # 33
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?
正解：C
解説：
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.
質問 # 34
A civil engineering technologist is performing a concrete test on a site. What minimum number of cylinders should the technologist make?
正解：B
解説：
Concrete compressive strength is verified using standardized specimens that represent the delivered concrete.
A typical field/lab testing program preparesa set of cylindersso strength can be checked at standard ages and so at least one specimen remains available if a test is invalid or confirmation is required. InExperiment Design for Civil Engineering, the compressive strength procedure explicitly states thatsets of four cylindersshould be prepared and thenone cylinder from each setis tested at7, 14, 21, and 28 days. This "four-cylinder set" directly supports the minimum needed to obtain a time-history of strength development through the common curing ages used in practice and referenced by ASTM C39 age tolerances. While many projects may require additional cylinders (for 7-day early breaks, hold cylinders, or additional acceptance tests), the question asks theminimumnumber, and the documented testing set described isfour.
