Preparation should be convenient and authentic so that anyone, be it a working person or a student, can handle the load. But now I have to tell you that all of these can be achieved in our Civil-Engineering-Technology exam preparation materials. The exam preparation materials of Real4test Civil-Engineering-Technology are authentic and the way of the study is designed highly convenient. I don't think any other site can produce results that Real4test can get. That is why I would recommend it to all the candidates attempting the Civil-Engineering-Technology Exam to use Civil-Engineering-Technology exam preparation materials.
NEW QUESTION # 11
A civil engineering technologist is providing culvert location staking in the field for a project. What information is placed on the survey stakes?
Answer: B
Explanation:
Construction staking is intended to communicatelocationandgradeto the crew in a form they can build from.
For pipe and culvert work, the controlling grade is theinvert(flow line), because pipe installation, bedding, and hydraulic performance are governed by the invert elevations at key points (typically inlet/outlet ends and along stationing). Standard staking practice records theoffset distancefrom a control line/centerline and the vertical informationneeded to establish the required grade at the feature being built. Civil surveying references describe that stake markings commonly include distances from control (left/right offsets) and elevation/grade relationships to the feature staked. For culvert/pipeline staking specifically, invert elevations are a primary requirement so that the installed pipe meets design slope and elevation. Therefore, the appropriate stake information is theculvert invert elevationsalong with theoffset to the end of the culvert, enabling accurate placement without occupying the excavation line.
NEW QUESTION # 12
The graph below is used for tracking progress and costs of a project for a client. What can be concluded about the project at week 10?
Answer: C
Explanation:
This type of chart is anEarned Value Management (EVM)progress/cost graph, typically showingPlanned Value (PV),Earned Value (EV), andActual Cost (AC)over time. Schedule performance at a given date (week 10) is determined by comparingEVtoPV. IfEV < PV, the amount of work actually accomplished (earned) is less than what was planned by that date, meaning the project isbehind schedule(Schedule Performance Index). In the provided graph, atweek 10theEV curve is below the PV curve, so the project has completed less work than planned by week 10, indicating schedule slippage. Budget performance is assessed separately by comparingEVtoAC(Cost Performance Index), but the question asks what can be concluded at week 10: the clear conclusion supported by the curves isbehind schedulebecause EV is lower than PV at week 10.
NEW QUESTION # 13
What subsurface sampling would be most likely conducted during a preliminary site investigation for a proposed building?
Answer: D
Explanation:
A preliminary site investigation for a building focuses on defining subsurface stratigraphy and basic engineering characteristics byexploring the ground and documenting soil/rock conditions versus depth.
Standard practice usesborings (drilling/boring)to obtain samples and observations, which are then recorded asborehole logsdescribing layers, groundwater, and recovered materials. The sampling provides representative soils for index testing and classification, but the fundamental "subsurface sampling" deliverables at the preliminary stage are thesoil samples retrievedand theborehole logsthat document what was encountered. Broader design deliverables like grading plans, final elevations, or pavement Marshall testing are not part of preliminary geotechnical sampling for a building footprint. Civil engineering references describe subsurface exploration as involving drilling/boring and retrieving soil/rock samples at various depths, with the engineer examining cuttings and recovered samples to characterize the profile-information typically captured in borehole logs.
NEW QUESTION # 14
A contractor is checking final grade elevation in advance of paving operations. What elevation needs to be confirmed before any asphalt is placed?
Answer: C
Explanation:
Before asphalt paving, the immediate supporting layer must be at the correct line and grade because asphalt thickness is builton top of the prepared base. Thetop of baseelevation controls final pavement structure thickness and the finished riding surface elevation when combined with asphalt lift thicknesses. If base grade is too high or low, the asphalt thickness will vary outside tolerance, which can affect performance (rutting, cracking), drainage crossfall, and tie-ins at structures and curbs. Standard field inspection practice therefore verifies base course elevations (and crossfall) immediately before paving so corrections (regrading
/recompaction) can be made while accessible. This fits typical roadway QA/QC sequencing: shape and compact subgrade/base to the specified elevations, confirm, then place asphalt lifts to achieve final grade.
Hence, the elevation that must be confirmed prior to placing asphalt istop of base.
NEW QUESTION # 15
What is the purpose of a spiral curve in highway design?
Answer: A
Explanation:
Aspiral (transition) curveis used in horizontal alignment to provide a gradual change in curvature from a tangent (infinite radius) to a circular curve (constant radius). AASHTO explains that spiral transition curves simulate the natural turning path of a vehicle and allow lateral acceleration (and side friction demand) to increase/decrease gradually as drivers enter/exit the circular curve, improving comfort and reducing encroachment. AASHTO also notes that the transition curve length provides a suitable location to develop superelevation runoffsmoothly from normal crown to full superelevation. These functions are specifically about transitioning into (and out of) the circular curve, not slowing traffic or transitioning vertical alignment.
Therefore, the purpose of a spiral curve isto transition into a circular curvewhile providing a smooth geometric and superelevation transition for drivers.
