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?
正解：B
解説：
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.

In the middle of the project, the client proposed an additional scope of work that requires a change order to the contract. Which statement applies to the contractor's percentage fee (i.e., mark-up) that should be added to the total amount in the change order?
正解：B
解説：
A change order is a formal amendment to the contract that adjusts scope, price, and/or time under therules already established by the contract documents. The contractor's fee (markup for overhead and profit) is not typically set unilaterally mid-project by either party; instead, the contract commonly defines how change work is priced (lump sum, unit rates, time-and-material) and what allowable markups apply. Industry guidance on change-order costing notes that the markup percentage is oftenincluded up front in the construction contractand applied consistently to change work, ensuring transparency and avoiding disputes during administration. This approach is consistent with standard contract administration practice: pricing of changes is governed by contract terms, and the change order documents implement those terms for a specific modification. Therefore, the contractor's percentage fee to be added to the change order amount isspecified in the contract documents.

What type of survey stake is shown in the image below?
正解：C
解説：
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.
質問 # 54
A continuous beam is supported in the middle and at both ends. It has a uniform load applied to the top. What will be the reactive forces at the supports?
正解：D
解説：
A beam supported at both ends and at an intermediate support is acontinuous (statically indeterminate) beam. Under uniform loading, continuity over the interior support createsnegative bending moment (hogging)at the middle support and redistributes shear and reactions compared with a simply supported span.
Standard structural analysis references note that continuous beams are statically indeterminate and are analyzed using methods such as thethree-moment equationto determine reactions and internal moments. For symmetric geometry and uniform load, the interior support typically attracts a larger share of the reaction because continuity restrains rotation and increases load transfer to the middle support. The end supports still carry reaction, but the redistribution generally results in themiddle reaction being greater than either end reactionfor the common case oh an intermediate support under uniform load. Thus, the correct statement is that the reactions aregreater in the middle than at the ends.
質問 # 55
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?
正解：B
解説：
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.
