Question 1
ప్రశ్న 1
An engineer must advise whether a proposed service reservoir and its access works are affordable before detailed drawings are finalized. What is the most appropriate purpose of an estimate at this stage?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
An estimate predicts probable quantities or expenditure before execution. At an early project stage, it helps decision-makers compare scope with available funds. A preliminary estimate can use suitable unit rates and allowances without complete itemwise measurements. Its accuracy depends on the level of project definition and the relevance of the data used. The estimate must be developed further as drawings, specifications and site information become available.

Question 2
ప్రశ్న 2
For a proposed compound wall, an engineer first computes 180 cubic metres of masonry and subsequently applies a rate of Rs 7,200 per cubic metre. Which distinction is correct?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
Quantity estimation determines the expected amounts of measurable work. Dimensions and relevant measurement rules are used to calculate those amounts. Cost estimation assigns applicable unit rates and other justified cost provisions to the estimated work. Multiplication of a quantity by its corresponding rate produces an estimated item amount. Both operations are related, but they serve distinct purposes in an engineering estimate.

Question 3
ప్రశ్న 3
A water-treatment building is only at concept-design stage, and an authority requires an approximate project cost before deciding whether to proceed. Detailed reinforcement and finishing drawings do not yet exist. Which estimate is normally appropriate?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A preliminary estimate is prepared when the general project concept is available but full design details may not be ready. It can be developed using plinth-area, service-unit or other suitable approximate methods. This approach provides a reasonable basis for early financial appraisal. Important inclusions and exclusions must be stated because specialized services can materially affect the total. A detailed estimate is subsequently prepared using more complete designs and measurement information.

Question 4
ప్రశ్న 4
Which information set is most appropriate for preparing a detailed estimate of a proposed reinforced-concrete pump-house building?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A detailed estimate identifies the work to be executed as measurable items. Drawings establish the geometry and quantities of those items. Specifications define materials, workmanship and the scope included in each item. Appropriate rates permit the quantities to be converted into item costs. Other necessary project provisions must be included transparently to obtain a meaningful total estimate.

Question 5
ప్రశ్న 5
A detailed measurement sheet lists excavation, concrete and masonry quantities separately. The engineer wants a concise statement showing each completed work item's quantity, rate, amount and the combined estimated cost. Which document best matches this purpose?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
An abstract of cost summarizes the itemwise financial information derived from a detailed estimate. It commonly shows descriptions, quantities, units, rates and amounts for the items. Individual amounts are obtained by applying their rates to the measured quantities. The item amounts and any clearly stated provisions are brought together into an estimated total. The abstract is a summary of the detailed estimate rather than an independent substitute for its measurements and specifications.

Question 6
ప్రశ్న 6
A planning team knows the approximate covered floor area of a simple building and has a comparable local cost per square metre of plinth area. Which preliminary estimating method uses these inputs directly?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The plinth-area method uses a defined building area and an applicable unit cost per square metre. It is often useful for approximate building estimates at early planning stages. Comparable buildings should have reasonably similar use, specification and construction conditions. Necessary adjustments or separate allowances may be required for services and site development. It does not replace detailed quantities once the design is ready.

Question 7
ప్రశ్న 7
For a preliminary building estimate, the applicable plinth area is 216 square metres and the adopted base rate is Rs 22,000 per square metre. No additional allowances are to be included in this question. What is the base estimated cost?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The problem provides the applicable plinth area and the base cost rate in compatible units. Under the plinth-area method, base cost equals area multiplied by the rate per square metre. Therefore the cost is 216 multiplied by Rs 22,000. The calculated amount is Rs 47,52,000. Additional services or allowances are deliberately excluded by the question and must not be introduced into this result.

Question 8
ప్రశ్న 8
A preliminary estimate uses the cubical-content method for a simple single-block building whose agreed estimating dimensions are 20 m by 10 m by 4 m. The adopted cost rate is Rs 4,500 per cubic metre, and the question excludes separate allowances. What is the estimated base cost?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The cubical content under the supplied dimensional convention is length multiplied by breadth multiplied by height. It equals 20 multiplied by 10 multiplied by 4, or 800 cubic metres. The estimated base cost is the volume multiplied by the given rate per cubic metre. Multiplying 800 by Rs 4,500 gives Rs 36,00,000. The result is a preliminary base figure and excludes the separate allowances expressly omitted from the question.

Question 9
ప్రశ్న 9
For an early cost comparison of two proposed water-treatment plants, the available benchmark is the cost per MLD of treatment capacity for similar facilities. Which statement is most defensible?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A service-unit method relates the probable cost of a facility to a relevant output or capacity measure. For a water-treatment plant, MLD can provide a useful preliminary comparison basis. Unit costs depend on treatment technology, capacity, equipment and site conditions. Costs may not increase in exact proportion to capacity because economies of scale and fixed components exist. The method is therefore appropriate for preliminary appraisal but not a substitute for detailed design and costing.

Question 10
ప్రశ్న 10
A trench for a pipeline has a specified uniform excavation width of 1.5 m, depth of 2.0 m and length of 12 m. Assume a rectangular excavation with no deductions or extra excavation. What is the estimated in-situ excavation quantity?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
Excavation of the stated rectangular trench is measured as a volume. The cross-sectional area is width multiplied by depth, or 1.5 multiplied by 2.0 equals 3.0 square metres. The excavation volume is the cross-sectional area multiplied by length. Multiplying 3.0 by 12 gives 36 cubic metres. Bulking of excavated material is not part of the in-situ volume specified in the question.
వివరణ:
Question 11
ప్రశ్న 11
An estimate contains 65 cubic metres of an excavation item at an adopted rate of Rs 900 per cubic metre. With no additional provision applicable to this item, what estimated amount should appear in the abstract?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The item's quantity is stated as 65 cubic metres. Its adopted unit rate is Rs 900 per cubic metre. The item amount equals the quantity multiplied by the corresponding rate. Thus 65 multiplied by 900 gives Rs 58,500. The matching unit in the quantity and rate is essential to obtain a correct estimated amount.

Question 12
ప్రశ్న 12
Consider the following proposed measurement-unit pairings: 1. Earth excavation — cubic metre; 2. Formwork to a concrete slab soffit — square metre of contact area; 3. Reinforcing steel — mass; 4. Pipeline laying — linear metre when the item specification provides measurement by length. Which pairings are appropriate?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
Excavation is ordinarily quantified by volume, so cubic metres are appropriate. Formwork to a slab soffit is measured by the area of formwork contact with the concrete. Reinforcement is generally measured by mass, such as kilograms or tonnes. Pipe laying may be measured by length when the applicable item description defines that basis. Measurement units must agree with the relevant specification and schedule-of-rates item.

Question 13
ప్రశ్న 13
Two estimates show identical quantities of masonry, but one specifies cement mortar of a stated proportion and the other specifies a different mortar and brick class. What must be checked before adopting the same unit rate?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
An item rate represents a defined scope of materials, labour, equipment and other cost components. Changing the brick class or mortar specification may alter the resources required. Equal quantities do not necessarily imply equal unit costs. The applicable schedule-rate description or a suitable rate analysis should be checked against the specifications. Using a rate for a materially different item can create a misleading detailed estimate.
వివరణ:
Question 14
ప్రశ్న 14
A detailed estimate includes an item absent from the adopted schedule of rates and located at a site with unusually long material haulage. Which rate-selection approach is most appropriate?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
Schedules of rates provide useful references for items matching their prescribed descriptions. A non-schedule item may require a market-based or analysed rate. Its material, labour, plant and transport requirements depend on the scope and site circumstances. The rate basis should be documented so that the estimate can be checked and updated. Rates should not be transferred blindly between unlike items or localities.

Question 15
ప్రశ్న 15
In Indian civil-engineering estimating terminology, the expression 'abstract estimate' is sometimes used for a preliminary or approximate estimate, while an 'abstract of cost' may refer to the itemwise summary of a detailed estimate. Which practice best avoids confusion between these uses?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
In some estimating references, an abstract estimate is another name for a preliminary or approximate estimate. An abstract of cost in detailed estimating practice is the itemwise financial summary derived from supported quantities and rates. These expressions should therefore not be assumed to have identical meanings in every context. Clearly stating the estimating stage, contents and supporting documents removes ambiguity. This distinction is important when preparing cost proposals for budgeting, approval and tendering.

Question 16
ప్రశ్న 16
A proposed project has only a conceptual layout, while another project has finalized working drawings and specifications. Which statement is correct about the stage of estimating?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The level of detail in an estimate depends on the design information available. Preliminary estimates are useful when scope is defined broadly but detailed drawings are incomplete. Detailed estimates require sufficiently developed dimensions, specifications and work items. An abstract of cost summarizes the item amounts from that detailed process. The estimate should be refined as project information improves.
వివరణ:
Question 17
ప్రశ్న 17
A contractor's rate for a specified item already includes loading, transport to site, unloading and placement. When preparing the estimate, how should these included operations normally be treated?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A unit rate must be understood together with its item description and inclusions. Costs already included in that rate form part of the priced work. Adding them again would duplicate a cost provision and inflate the estimate. Separate charges may be justified only for genuinely additional work not covered by the item. Transparent rate assumptions help prevent both omissions and double counting.

Question 18
ప్రశ్న 18
An estimate contains a stated contingency provision for unforeseeable minor requirements. What is the most appropriate interpretation of that provision?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A contingency allowance addresses some uncertainty associated with the estimate. Its basis should reflect the project, estimating stage and applicable organizational requirements. Known works should still be measured or otherwise allowed for explicitly. A contingency is not proof that future costs cannot exceed the estimate. It should be identified separately where appropriate and not counted again through overlapping provisions.

Question 19
ప్రశ్న 19
A detailed estimate was sanctioned for a water-supply building, but subsequent design changes and updated quantities show that the probable cost of the originally sanctioned work will exceed the approved estimate beyond the variation permitted by the governing procedure. Which estimate is generally called for?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A revised estimate deals with material changes to the expected cost of previously sanctioned work under the applicable procedure. It should explain how quantities, rates or other factors differ from the existing estimate. The comparison allows the competent authority to assess the need for further approval. Permissible variations and approval procedures depend on the governing rules. A supplementary estimate addresses a different situation in which additional work outside the original sanctioned scope is proposed.

Question 20
ప్రశ్న 20
During the execution of a sanctioned pump-house project, the client requires an additional security cabin that was not included in the original scope. The other sanctioned work remains substantially unchanged. Which estimate most directly addresses the new cabin?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A supplementary estimate provides for work additionally proposed beyond the original sanctioned scope. The security cabin is described as an additional requirement rather than a cost variation within an existing item. Its quantities, rates and justification should be documented. Appropriate sanction requirements must be followed before undertaking the added work. The supplementary amount is considered together with the original sanctioned estimate for the overall cost position.
వివరణ:
Question 21
ప్రశ్న 21
A construction project has BOTH a significant increase in the probable cost of originally sanctioned items and a separately requested new generator building that was not in the sanctioned scope. Which treatment is most defensible?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
An increase in the probable cost of existing sanctioned items can require a revised estimate under the applicable rules. A genuinely new building introduces additional work outside the original scope. These are different reasons for changing the sanctioned financial provision. Depending on the governing procedure, they may be documented through appropriate revised and supplementary provisions. A clear comparison and justification help prevent double counting or omission of either change.

Question 22
ప్రశ్న 22
Consider these statements about estimating: 1. A preliminary estimate may be prepared before itemwise working drawings are complete. 2. Detailed quantities should be supported by dimensions and specified measurement units. 3. An abstract of cost commonly summarizes item quantities, unit rates and item amounts. Which statements are correct?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
A preliminary estimate is intended to assist early appraisal even when detailed drawings are incomplete. Detailed quantity estimation is based on defined work items and measured dimensions. Those quantities must be expressed in units matching the relevant item specifications. An abstract of cost summarizes the quantity, rate and amount information for completed items of work. Therefore all three statements describe valid and mutually consistent parts of the estimating process.

Question 23
ప్రశ్న 23
An engineer is asked to distinguish estimated cost, tendered cost and actual cost on a public works project. Which statement is correct?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
An estimated cost is a forecast developed from quantities, rates and stated assumptions. Tendered cost results from a contractor's price offer under the relevant tender basis. Actual project expenditure is established from the work and costs incurred during execution. Variations, unforeseen conditions and price changes can cause these values to differ. Understanding the distinction is necessary for budgeting, procurement and cost control.

Question 24
ప్రశ్న 24
A quantity sheet shows 120 m of pipeline at Rs 1,500 per metre, but its abstract accidentally uses 1,200 m at the same rate. Assuming no other changes, by how much is the abstract overstated?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The supported pipeline length is 120 m, whereas the abstract incorrectly uses 1,200 m. The excess quantity entered is 1,200 - 120 = 1,080 m. The item rate is Rs 1,500 for each metre. The overstatement equals 1,080 multiplied by 1,500, or Rs 16,20,000. Cross-checking abstracts against detailed measurement sheets helps identify such transcription errors.

Question 25
ప్రశ్న 25
For a new elevated service reservoir project, conceptual drawings are used to prepare an initial budget; later, detailed structural and service drawings, item specifications and applicable rates become available. Which sequence best represents sound estimating practice?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
The conceptual-stage estimate supports an initial project decision using incomplete design information. Developed structural and service drawings permit the work to be broken into measurable items. Detailed measurements and applicable rates then provide a better-supported cost forecast. An abstract of cost assembles the resulting item amounts and stated provisions. This sequence helps the project team improve cost reliability while preserving a checkable basis for approval and procurement.
