NEW QUESTION # 78
A contractor fails to make the necessary repairs on the deficiency list within the specified timeline and refuses to return to the site. How should the owner proceed in this situation?
Answer: D
Explanation:
A performance bond is a form ofperformance securityintended to protect the owner (obligee) if the contractor defaults on contractual obligations-such as refusing to return to correct deficiencies. Guidance on construction bonds explains that performance bonds provide the employer/owner a remedy when a contractor fails to fulfill obligations, allowing the owner to access bond proceeds or require the surety's involvement to address non-performance (often to fund completion/correction or compel action, subject to bond terms and notice requirements). Practical bond guidance also notes that the presence (or threat) of a bond call can be used to persuade a contractor to return to site to correct defects, and that bonds are specifically used to address contractor default. Therefore, when a contractor refuses to return and deficiencies remain unresolved within the required timeline, the appropriate owner action-following the bond's procedural requirements-is to engage the contractor's performance bond.
NEW QUESTION # 79
A 500 mm diameter corrugated steel culvert conveys storm water under a road. The inlet end projects from the road embankment fill. How much flow (m³/s) can the culvert handle before the headwater depth is greater than the culvert diameter?
Answer: B
Explanation:
For a projecting inlet, the controlling condition is typicallyinlet controlat relatively low headwater ratios.
Using the FHWA/HDS-5 style inlet-control nomographs reproduced in the Minnesota DOT Drainage Manual (Chart 2: "Headwater depth for C.M. pipe culverts with inlet control"), a corrugated metal pipe (CMP) with a diameter near500 mm (# 20 in.)and aprojectingentrance type corresponds to a discharge on the order of~7 cfs whenHW/D # 1.0(headwater approximately equal to the culvert diameter). Converting 7 cfs to SI givesm³/s.
This magnitude is consistent with the inlet-control relationship that headwater increases with discharge for a given culvert diameter and entrance configuration, and that small culverts (0.5 m) carry flows measured in tenths of m³/s, not multiple m³/s at HW/D # 1.
NEW QUESTION # 80
A contractor is using a compactor on a hot and dry day and quickly compacts a dry 300 mm thickness of sub- base without adding water. The soil is near optimum moisture. A civil engineering technologist completes compaction tests and finds that specifications have not been achieved. What should be done?
Answer: A
Explanation:
Compaction acceptance is based on achieving specifiedin-place dry density(relative compaction) at an acceptable moisture range. If the material is alreadynear optimum moisture, failure to meet density typically points toinsufficient compactive effort,inadequate number of passes,improper equipment, orexcessive lift thickness(300 mm can be too thick for some sub-base and equipment combinations). Standard compaction theory shows that near OMC, soils should densify efficiently; if density is still low, the first corrective action is toincrease compactive effortand verify results with another field density test. Adding water when already near OMC may push moisture above optimum and can reduce achievable dry density.
Continuing with base placement would lock in a nonconforming layer, and stripping/importing new material is a last-resort remedy after reasonable rework attempts. Therefore, the best immediate corrective action is to re-compact and retest, adjusting lift thickness/passes as needed to meet specification.
NEW QUESTION # 81
Which joints in concrete slab construction determine the location of cracks?
Answer: A
Explanation:
Concrete slabs shrink as they cure and experience temperature/moisture changes. Because the slab is restrained by subbase friction and adjacent elements, tensile stresses develop and cracking is likely unless the slab is intentionally "weakened" at planned locations.Control joints(also called contraction joints) are formed or saw-cut to create a deliberate plane of weakness so that shrinkage cracking occurswhere intended, producing straighter, serviceable cracks that are easier to seal and maintain. Technical references describe contraction/control joints as placed at regular intervals specifically tocontrol random crackingby encouraging the crack to form along the joint line, relieving tensile stresses in the slab. Expansion joints address thermal expansion, isolation joints separate the slab from fixed elements, and construction joints occur where placements stop and start; none of those are primarily intended tocontrol crack locationthe way control joints are. Therefore, the joint type that determines where cracks occur is thecontrol joint.
NEW QUESTION # 82
For a land development project to be initiated, which of the following documents must be submitted to the municipality for approval?
Answer: C
Explanation:
Municipal land development commonly requires an approvedstatutory planthat establishes the framework for land use, servicing, staging, and transportation within the development area before detailed subdivision
/engineering can proceed. In many Alberta municipalities (e.g., Edmonton), aNeighbourhood Structure Plan (NSP)is the statutory neighbourhood-level plan used to initiate and guide new neighbourhood development, and municipal documents describe NSPs as beinginitiated by landowners/developersand prepared in cooperation with municipal administration for council consideration/approval. While Area Structure Plans (ASPs) can also be used in some contexts, the document explicitly associated with initiating a new neighbourhood-level land development project in the referenced municipal framework is theNeighbourhood Structure Plan. A historical resources overview and transportation network analysis may be required supporting studies, but they are not the primary statutory plan used to initiate the development. Therefore, the correct answer isNeighbourhood Structure Plan.
