Test 18 - Integrated General Specifications

Question 1 ప్రశ్న 1

A small pump-house has shallow strip foundations, brick superstructure walls, an RCC roof, internal plaster and tiled floors. Which overall sequence best represents satisfactory execution and inspection?

A Start foundation concreting before checking formation level, then inspect and measure the concealed excavation only after backfilling. B Complete roof concreting and wall finishing while leaving service chases and plinth filling uncoordinated. C Place foundation concrete and immediately cover its edges with backfill without checking levels or preserving required curing and inspection access. D Inspect and prepare excavations, construct and cure the specified foundations, erect and inspect masonry and RCC, then carry out prepared and cured finishes in their appropriate sequence.

Question 2 ప్రశ్న 2

While excavating a foundation trench for a pump-house, workers encounter an unrecorded existing water main. Which combined execution and measurement response is appropriate?

A Continue excavation at the original pace and charge all damage to the finishing-work item. B Stop potentially damaging work locally, protect and identify the utility, obtain instructions for any revised excavation or support, and record authorized changes under the appropriate earthwork items. C Cast PCC around the unidentified pipe immediately so that its position need not be recorded. D Continue under the original work method and quantities without separately recording the utility-related constraints or any approved variation.

Question 3 ప్రశ్న 3

An excavation for a stone-masonry foundation is accidentally taken below the approved formation level. The contractor proposes throwing loose soil back into the bottom and placing PCC over it. What should the engineer require?

A Record the deviation and restore the formation by an approved engineered treatment before PCC placement, without assuming unauthorized extra excavation is payable. B Accept loosely tipped soil because the weight of PCC will always consolidate it sufficiently. C Restore the level by arbitrarily increasing the PCC thickness without checking whether the proposed treatment is approved. D Treat the entire unauthorized overbreak as additional payable excavation and proceed without formal rectification approval.

Question 4 ప్రశ్న 4

An excavation trench is 10.0 m long, 1.20 m wide and 1.50 m deep. It contains a full-width 0.10 m thick PCC bed and, directly above it, a 10.0 m long stone foundation 0.80 m wide and 0.50 m high. Assuming both elements lie entirely within the trench, the remaining void is backfilled, and no other allowances or deductions apply, what is the theoretical compacted backfill volume?

A 12.80 m3. B 14.00 m3. C 16.80 m3. D 18.00 m3.

Question 5 ప్రశ్న 5

The drawings specify cement-mortared random rubble for a foundation wall and brick masonry above plinth level. The contractor wants to use brick masonry throughout and retain the rubble item rate. Which decision is most appropriate?

A Treat brick and rubble as identical because both use cement mortar. B Approve the change solely if the brick dimensions match the stone lengths. C Measure the substituted brickwork as rubble without revising drawings or rates. D Require technical and contractual approval for the changed material and detail, then measure and value the accepted work under the correct descriptions.

Question 6 ప్రశ్న 6

Brick masonry around a door opening is complete, and an in-situ RCC lintel is scheduled. The brick jamb levels differ and the lintel formwork is not properly supported. What should happen before concreting?

A Pour the lintel and make up the uneven bearing level later with a thicker plaster coat at the jambs. B Keep the inadequate supports and reduce concrete workability to prevent movement of the shuttering. C Correct the masonry seating and bearing to the approved detail, secure and inspect the formwork and reinforcement, then authorize placing of the lintel concrete. D Check the required lintel bearing but defer the formwork stability and reinforcement inspection until after casting.

Question 7 ప్రశ్న 7

A brick partition meets an existing stone-masonry wall at a new opening. What is the most appropriate specification response at this junction?

A Rely on the later plaster coat alone to create a structural bond between the walls. B Follow the approved junction detail, providing the specified bonding or anchorage and a suitable finish treatment for the two backgrounds. C Form a straight rigid butt joint with no approved connection detail and rely on a cement-plaster coat to mask the junction. D Break out existing stone units indiscriminately to create brick toothing without checking stability or obtaining approval for the junction detail.

Question 8 ప్రశ్న 8

Just before pouring an RCC plinth beam spanning masonry bays, inspection finds displaced stirrups, missing cover blocks and an unapproved electrical sleeve passing through the beam formwork. Which action is correct?

A Hold the pour, restore the approved reinforcement and cover, resolve the sleeve detail with the designer, and reinspect the work before placing concrete. B Allow the pour after loosely tying the displaced stirrups, expecting concrete pressure to restore their positions. C Move the main bars inward to create extra space for the sleeve without confirming that the revised reinforcement arrangement is approved. D Record the defects only after the beam is plastered and whitewashed.

Question 9 ప్రశ్న 9

A rectangular pump-house room measures 6.0 m by 4.0 m. Its RCC structural slab is 150 mm thick, and a separately specified cement-concrete floor topping is 40 mm thick over the same full area. With no openings or deductions, which pair of in-place volumes is correct?

A RCC 0.96 m3; floor topping 3.60 m3. B RCC 4.56 m3; floor topping 4.56 m3. C RCC 3.60 m3; floor topping 0.96 m3. D RCC 24.00 m3; floor topping 24.00 m3.

Question 10 ప్రశ్న 10

An estimate includes RCC roof beams, reinforcing bars, beam formwork and a separately specified ceiling plaster. With no composite-item clause, which approach avoids measurement duplication?

A Measure all four items only as roof plan area without separate descriptions. B Include steel mass within beam concrete volume and pay for it again as reinforcement. C Assume all specified plaster is included under the normal formed-concrete surface finish without checking its separate item description. D Measure RCC concrete by its appropriate volume, reinforcement separately, formwork by contact area and specified plaster by finished surface area, subject to contract inclusions.

Question 11 ప్రశ్న 11

A contractor wants to plaster the underside of a recently cast RCC roof while its centering is still in place and roof work above may disturb the slab. What is the appropriate sequence?

A Begin plastering as soon as a small soffit area is exposed, despite incomplete slab operations and unremoved form-release residue. B Complete the required structural operations and authorized formwork removal, then prepare and plaster the accessible RCC soffit before the subsequent ceiling finish. C Remove the formwork prematurely solely to accelerate plastering, without structural clearance. D Apply plaster onto exposed oily form-release material immediately after striking one panel.

Question 12 ప్రశ్న 12

An RCC roof and adjoining cement-mortar brick masonry are being cured, while the contractor wants to whitewash freshly applied wall plaster on the following day. Which scheduling decision is correct?

A Maintain the required curing for each cementitious operation, allow the plaster to become suitable for coating, and then apply the specified wash sequence. B End all RCC and masonry curing as soon as the plaster is applied. C Whitewash wet, green plaster immediately because the wash replaces cement-plaster curing. D Cure the RCC but allow the fresh cement plaster to dry rapidly and treat the subsequent wash coats as adequate protection.

Question 13 ప్రశ్న 13

An exposed RCC column and brick infill wall will be cement plastered as one visual plane. An approved detail specifies treatment of their junction to control cracking. What should the finishing team do?

A Place the whole plaster thickness over an uncleaned column and rely on the brick joints for bonding. B Omit the junction treatment because the final colour wash will bridge any movement. C Prepare both backgrounds correctly, fix the approved junction treatment in its specified position, and plaster to the required plane and thickness. D Apply different uncontrolled water-cement ratios to the two sides and ignore the approved detail.

Question 14 ప్రశ్న 14

The lower exposed face of a stone-masonry wall will be pointed, but an adjoining brick portion is specified to receive cement plaster and subsequent colour wash. Which work description is correct?

A Plaster both faces and claim pointing as an additional finish over the completed plaster. B Colour wash the unprepared stone joints and leave the plaster background dusty. C Use the stone-pointing rate for the entire brick and stone surface because mortar appears in both works. D Prepare the stone joints for the specified pointing, prepare the brickwork for plaster, and measure the distinctly specified finished areas without duplicate coating items.

Question 15 ప్రశ్న 15

After construction of masonry plinth walls, the contractor wants to lay floor tiles directly over loose, uncompacted plinth filling before the specified floor base is formed. Which intervention is correct?

A Increase only the tile adhesive thickness to compensate for the uncontrolled filling. B Place approved fill in controlled compacted layers, establish the specified floor base and levels, and then lay the finish over the prepared substrate. C Spread a levelling layer of dry sand over the loose filling and proceed with floor finishing without confirming compaction. D Place the plinth fill in one deep lift and rely on the weight of the later floor base to densify it.

Question 16 ప్రశ్న 16

The specified finished floor level is RL 100.000 m. The approved tile system consists of a 20 mm mortar bed and 10 mm thick tiles, with no other levelling layer. At a location where no floor slope is required, what should be the prepared base level?

A RL 99.970 m. B RL 99.980 m. C RL 100.030 m. D RL 100.000 m.

Question 17 ప్రశ్న 17

A drain-room floor must fall at 1 in 120 over a horizontal distance of 3.60 m toward its drain. What finished-level fall is required, and how should it be coordinated with tile laying?

A 12 mm fall, obtained by increasing grout-joint width near the drain. B 120 mm fall, formed by allowing random tile thickness variations. C 30 mm fall, formed through the approved substrate or bedding levels while maintaining proper tile support and finish. D 3 mm fall, which may be ignored after applying a smooth finish.

Question 18 ప్రశ్న 18

An existing RCC slab has a designed movement joint that continues beneath new cement-mortar tile flooring and nearby wall finishes. Which integrated detailing choice is appropriate?

A Bridge the joint rigidly with tile adhesive and plaster because movement occurs only in the structural slab. B Conceal the joint with a continuous grout line and record it as completed expansion-joint work. C Fill the gap with unapproved ordinary mortar so that the surface appears uninterrupted. D Carry the movement provision through affected finishes using the approved flexible joint or profile details while keeping surrounding bedding and plaster sound.

Question 19 ప్రశ్న 19

Internal cement plaster, floor tiles, tile skirting and colour wash are specified for a newly built room. Which finishing sequence best limits damage and achieves a uniform appearance?

A Apply the final colour wash before curing the plaster and then cut skirting grooves through the finished coating. B Complete and cure the wall plaster, lay and protect the finished flooring and skirting, then apply the approved wash to suitable dry backgrounds with adjacent finishes protected. C Lay and grout floor tiles on an unprepared base before closing masonry chases and plastering. D Apply an initial wash coat to uncured plaster and omit subsequent protection of completed tile and skirting joints.

Question 20 ప్రశ్న 20

A room measures 5.0 m by 4.0 m internally and is 3.0 m high. Its four walls and entire ceiling will receive plaster and later a wash finish. For this simplified take-off, fully deduct one 0.90 m x 2.10 m door and one 1.20 m x 1.50 m window from the wall faces, add no reveals, and make no other adjustment. What is the combined finished area for EACH trade?

A 70.31 m2. B 74.00 m2. C 72.11 m2. D 50.31 m2.

Question 21 ప్రశ్న 21

A new internal brick wall has received cement plaster and is specified to receive lime-based colour wash after the background is ready. Which description correctly links the plaster and colour-wash specifications?

A Apply colour pigments straight into wet plaster and omit the colour-wash item. B After plaster curing and suitable drying and cleaning, provide the specified primary whitewash and succeeding colour-wash coats, checking the approved shade and separate rate scope. C Apply the final colour wash before the plaster has been brought to line and level. D Omit the whitewash base because the cement plaster alone is assumed to satisfy the specified lime colour-wash priming requirement.

Question 22 ప్రశ్న 22

An existing soot-stained pump-house wall is to be colour-washed, while new floor tiles and glazed panels nearby are already finished. Which combined preparation and protection method is most appropriate?

A Apply colour wash over soot so that there is no risk of disturbing the floor tiles. B Use abrasive cleaning without protecting the glazing and treat any scratches as unrelated work. C Remove soot and unsound old coating by the approved cleaning procedure, prepare the surface for the specified wash system, and protect and clean adjacent finishes. D Wet-clean the soot only superficially and apply extra colour-wash coats without verifying removal of contamination or protecting completed floor joints.

Question 23 ప్రశ్న 23

An estimate includes an isolated 3.0 m x 2.0 m RCC platform slab 150 mm thick, a separately specified tile finish covering its full top area, and 3.0 m x 2.5 m plaster on one adjacent wall face. With no openings or deductions, which quantities correspond to these three items respectively?

A RCC 6.00 m3; tile finish 0.90 m2; plaster 7.50 m2. B RCC 0.90 m2; tile finish 6.00 m3; plaster 7.50 m3. C RCC 0.90 m3; tile finish 7.50 m2; plaster 6.00 m2. D RCC 0.90 m3; tile finish 6.00 m2; plaster 7.50 m2.

Question 24 ప్రశ్న 24

For a simplified dry-material estimate, tile bedding needs 0.50 m3 of combined dry cement and sand at 1:4, while wall plaster needs 0.35 m3 at 1:6. Ignore bulking, changes in yield and wastage; keep the mixes separate during execution. What are the TOTAL dry cement and sand volumes respectively?

Question 25 ప్రశ్న 25

At final measurement, a contractor submits one composite claim for excavation, stone footings, RCC, wall plaster, tile flooring and colour wash, without dimensions or trade-specific test records. Which response is most appropriate?

A Accept the claim because all work belongs to a single pump-house building. B Certify the submitted total at schedule rates without reconciling the actual dimensions of each trade item. C Require auditable item-wise measurements and relevant quality records, checking the approved materials, workmanship, curing, test results and contract inclusions before certifying the work.
