問題 #75
The road cross sections shown have chainage (CH) 1+100 and 1+200. What is the volume of sub-grade material if an averaging method is applied?
答案：A
解題說明：
The averaging method for earthworks between two stations is theAverage End Areamethod:
whereandare the end areas at the two cross sections andis the station spacing. Here, CH 1+100 to 1+200 givesm. From the cross-section labels in the figure, the two sub-grade areas sum to4.26 m²(e.g., approximately 1.31 m² and 2.95 m²), so the average area ism². Multiply by length:m³. This is the standard approach used for roadway cut/fill and subgrade volume computations between surveyed sections.
問題 #76
The critical path refers to which of the following series of tasks in a schedule?
答案：B
解題說明：
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.
問題 #77
What personal protective equipment is most important when surveying near active traffic?
答案：B
解題說明：
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.
問題 #78
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?
答案：D
解題說明：
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.
問題 #79
What is a silt fence used for?
答案：D
解題說明：
A silt fence is an erosion and sediment control measure intended toretain sedimentcarried by runoff, reducing offsite sedimentation. Lindeburg describes temporary silt fences as measures using posts and filter cloth (e.g., filter fabric) placed on the upstream side toretain suspended silt particles in runoff water. This purpose is to reducesoil movement(sediment transport) caused by erosion processes during construction, especially oalong drainage paths where siltation is expected. The fence does not "stop water" (runoff still passes through while sediment is filtered), is not primarily a site limit marker, and is not an access control barrier for the public. Therefore, the correct statement is that a silt fence is usedto prevent soil from moving through the site due to erosion.
