問題 #10
Typically, what is the maximum time that concrete can be in a mixer truck before it is discharged?
答案:C
解題說明:
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.
問題 #11
Prior to entering an active construction site, what must all visitors do?
答案:B
解題說明:
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.
問題 #12
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?
答案:D
解題說明:
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).
問題 #13
A subcontractor is completing surface rehabilitation in a mature community. What are the minimum requirements for quality that must be met?
答案:A
解題說明:
In municipal surface rehabilitation, the governing minimum quality requirements are set by themunicipality's standards/specifications, because the work interfaces with, affects, and is often handed over to municipal infrastructure (roads, sidewalks, utilities, drainage). Municipal specifications define accepted materials, compaction/density requirements, asphalt/concrete placement tolerances, testing frequency, restoration details, and acceptance criteria. Contractor or subcontractor internal specs may exceed municipal requirements, and warranties/insurance address risk allocation, but they do not replace theowner/authority's technical acceptance standards. In civil engineering practice, "specifications" are the formal technical requirements that the delivered system must meet (minimum/maximum/range), including items like minimum density of roadbed, tolerances, and material performance-these are typically established by the owning agency (here, the municipality) for public infrastructure assets. Thus, the minimum quality threshold is defined by themunicipality specifications.
問題 #14
A civil engineering technologist has been given the task of drawing a foundation plan for a building that measures 20 m × 30 m. The drawing will be produced on a C1 sized sheet, which measures 648 mm × 917 mm. Which of the following is the best scale for the plan?
答案:A
解題說明:
Selecting a drawing scale is an engineering graphics task: the plan must fit within the sheet limits after allowing for borders, title block, notes, dimensions, and details. Engineering drawing practice treats scale as a proportional reduction ratio that preserves geometric similarity between the real object and the drawing. A 20 m × 30 m footprint equals 20,000 mm × 30,000 mm. At 1:50, the plotted size is 400 mm × 600 mm, which fits comfortably on a 648 mm × 917 mm sheet with room for margins and annotations. At 1:25, the plotted size becomes 800 mm × 1,200 mm, which exceeds the sheet. At 1:5, it is far too large; at 1:250, it is very small (80 mm × 120 mm), reducing readability for foundations that typically require clear dimensioning of footings, piles, grade beams, and notes. Therefore, 1:50 provides the best balance of fit and legibility for a C1 sheet, makingOption Cthe best scale choice.
