NEW QUESTION # 39
The invert elevation of a sanitary sewer line is 98.150 m, the pipe thickness is 12 mm and its outside diameter is 600 mm. Using the image below, what is the crown elevatf m
Answer: D
Explanation:
Invert elevation is the elevation of theinside bottomof the pipe. With outside diameterm and wall thicknessm, the inside diameter ism. The vertical distance from invert (inside bottom) to theoutside top of pipeism, giving the outside top-of-pipe elevation:m. The section detail in the provided image shows the vertical cover from top of pipe to top of asphaltas approximately2.476 m(dimensioned in the road section). Adding this cover gives the road crown elevation:m, matching optionA. This uses standard civil geometry conversions between invert, pipe dimensions, and surface elevations used in utility/roadway inspection and verification.
NEW QUESTION # 40
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?
Answer: A
Explanation:
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.
NEW QUESTION # 41
A civil engineering technologist is installing offset stakes for centreline at 25-metre stations. What information is typically found on the stakes?
Answer: C
Explanation:
Offset stakes are used to carry alignment control when the true centreline point is impractical to occupy (e.g., within excavation, traffic, or unstable ground). Standard field staking practice marks the station and identifies theoffset distanceto the actual centreline so crews can pull the correct perpendicular distance back to the design line. Because construction also needs grade control, the stake commonly includes thecentreline elevation (or cut/fill to grade)at that station to guide grading or excavation. Surveying and construction layout practice emphasize that stakes should communicate the essential geometry:wherethe design line is (by station and offset) andwhat elevation/gradeapplies at that location. Options involving ditch depth or top-of- cut are specific to slope/ditch staking rather than centreline offset stakes. Therefore, the typical information on centreline offset stakes iscentreline elevation and offset distance.
NEW QUESTION # 42
A civil engineering technologist is working on a foundation design and needs to differentiate between different sections of a footing and the point where the vertical pressure is applied. In the diagram, what is represented by letters A, B, and C?
Answer: C
Explanation:
In shallow foundation terminology, thefootingis the widened base element that transfers loads to soil over a larger area to reduce bearing pressure, while apedestalis the short vertical element (often concrete) that supports a column or provides an interface between the column/base plate and the footing. Vertical load from the superstructure is shown as adownward forceapplied at the top of the pedestal/column location, representing thevertical pressure/loadtransmitted into the foundation system. In the diagram, letterBpoints to the large horizontal base element (the footing), letterApoints to the smaller vertical block above it (the pedestal), and letterCmarks the downward applied load. This matches standard foundation component identification used in structural and geotechnical detailing: pedestal above, footing below, and vertical load applied at the top of the pedestal/column line of action.
NEW QUESTION # 43
A surveyor is laying out the invert elevations of a storm sewer. Centre elevation is 10 m, storm pipe outside diameter is 1 m, and storm sewer pipe wall thickness is 0.05 m. What is the storm sewer invert elevation in the diagram below?
Answer: B
Explanation:
Theinvert elevationis the elevation of theinside bottomof the pipe (flow line). To compute invert from a reference elevation, the key geometry is theinside radius(half the inside diameter). Given an outside diameter (OD) of 1.00 m and wall thickness of 0.05 m, the inside diameter (ID) is: ID = 1.00 # 2(0.05) =0.90 m, so inside radius =0.45 m. The diagram indicates the pipe is located such that thepipe centreline elevationis at
7.00 m(derived from the shown vertical offset from the 10.00 m center elevation to the pipe center). The invert is therefore: 7.00 # 0.45 =6.55 m. Civil references define invert as the interior bottom of the conduit and use inside radius/diameter relationships when converting from centreline to invert. Hence, the correct invert elevation shown by the diagram and pipe geometry is6.55 m.
