Explanation: Approximate cost of sewerage project for a population of one [email protected] Rs. 100/- head works out as Rs. 100 lakhs.
8. Cube rate estimate is less accurate as compared to the plinth area estimate as the height of the building is also compared.
Explanation: Cube rate estimate is most accurate as compared to the plinth area estimate as the height of the building is also compared.
9. For storeyed building plinth area estimate is not prepared for each storey separately.
Explanation: For storeyed building plinth area estimate is prepared for each storey separately.
10. __________ is prepared on the basis of plinth area of building, the rate being deducted from the cost of similar building having similar specification, heights and construction, in the locality.
a) Cube Rate Estimate
b) Supplementary Estimate
c) Maintenance Estimate
d) Plinth Area Estimate
Explanation: Plinth area estimate is calculated by finding the plinth area of the building and multiplying by the plinth area rate. The plinth area should be calculated for the covered area by taking external dimension of the building at the floor level.
11. ________________ is the amount provided in the estimate and bill of quantities for some specialised work to be done by a specialised firm; whose details are not known at the time of preparing estimate.
a) Prime cost
b) Provisional sum
c) Capital cost
d) Building cost index
Explanation: The work like installation of refrigerating machine; installation of lift, air conditioning, etc., for which full information and details may not be known at the time of preparing estimate and entering into contract and are require to be installed by a specialised firm, a sum.
12. In this method approx. total length of walls is found in running metre and this total length multiplied by the rate per running metre of wall gives a fairly accurate cost.
a) Annual repair
b) Item rate estimate
c) Approximate quantity method estimate
d) Cubical content estimate
Explanation: For this method the structure may be divided into two parts viz. Foundation including plinth and Superstructure.
13. _______________ estimate is a detailed estimate and is prepared to maintain the structure or work in proper order and safe condition.
a) Supplementary and revised estimate
b) Maintenance estimate
c) Item rate estimate
d) Revised estimate
Explanation: For building; this includes white washing, colour washing, painting, minor repairs etc. For road works the A.R. estimate provides for patch repairing, renewals, repair of culverts, etc.
14. A large work or project may consists of several building or small works and each of these work is known as ___________
Explanation: Detailed estimate of each sub-work is prepared separately and accounts of expenditure are kept sub-work wise.
15. The term ______________ is used to denote a procedure of costing or valuing an item of work on the basis of actual labourers and materials required.
a) prime cost
Explanation: Certain items of work which cannot be measured as- a design in the plaster work, front architectural finish of a building, work under water, etc. are valued and paid by ‘day work’. In such cases the schedule of rates of materials and different classes of labourers likely to be engaged in th work should be included in the tender and in contract agreement.
