11. Which of the following is the most correct estimate?

Correct Answer: C. Detailed estimate
Solution:Estimating is the most important of the practical aspects of construction management, and the subject deserves the closest attention of one aspiring to a career in the profession.

Detailed Estimate: A detailed estimate of the cost of a project is prepared by determining the quantities and costs of every thing that a contractor is required to provide and do for the satisfactory completion of the work. It is the best and most reliable form of estimate. A detailed estimate may be prepared in the following two ways:

(a) Unit quantity method
(b) Total quantity method.

(a) Unit Quantity Method: In the unit quantity method, the work is divided into as many operations or items as are required. A unit of measurement is decided. The total quantity of work under each item is taken out in the proper unit of measure-ment. The total cost per unit quantity of each item is analyzed and worked out. Then the total cost for the item is found by multiplying the cost per unit quantity by the number of units.

This method has the advantage that the unit costs on various jobs can be readily compared and that the total estimate can easily be corrected for variations in quantities.

(b) Total Quantity Method: In the total quantity method, an item of work is divided into the following five subdivisions: (i) Materials; (ii) Labour (iii) Plant; (iv) Overheads; (v) Profit.

12. The technique of finding the fair price of an existing building or property is known as ________.

Correct Answer: B. Valuation
Solution:Real estate appraisal, property valuation or land valuation is the process of developing an opinion of value for real property. Real estate transactions often require appraisals because they occur infrequently and every property is unique, unlike corporate stocks, which are traded daily and are identical.

The location also plays a key role in valuation. However, since property cannot change location, it is often the upgrades or improvements to the home that can change its value. Appraisal reports form the basis for mortgage loans, settling estates and divorces, taxation, and so on. Sometimes an appraisal report is used to establish a sale price for a property.

13. The value of the property (without being dismantled) at the end of the useful life period is known as _________.

Correct Answer: B. Salvation value
Solution:Salvage value: This is the estimated value of the asset when it is retired from service, traded-in, disposed of, or exhausted.

The term 'scrap value' is sometimes used in place of salvage value, since an asset's value at the end of its useful life is often merely its value as scrap.

An asset may have a salvage value of zero.
Note: Any asset can only be depreciated down to its salvage value.
cost depreciation → salvage value

14. The value of the dismantled material less the cost of dismantling is called _________.

Correct Answer: A. Scrap value
Solution:Book value is the original investment less the depreciation for the period of existence. Salvage value is the value at the end of useful life period without being dismantled. Scrap value is the value of the dismantled material less the cost of dismantling.

15. The plan of a building is in the form of a rectangle with centre line dimensions of outer walls as 14.7m × 9.7 m. The thickness of the wall in super structure is 0.30 m. What is the floor area of the building?

Correct Answer: D. None of these
Solution:No explanation given in the book

16. If the bearing is not specified for the lintel, in the estimation it is usually taken as _________.

Correct Answer: A. thickness of lintel subjected to a minimum value of 12 cm
Solution:No explanation given in the book

17. In the estimation of plastering surface the deductions are not made for _________.

Correct Answer: D. None of these
Solution:No explanation given in the book

18. The approximate volume of cement required to prepare 100m³ of 1 : 2 : 4 concrete is ________.

Correct Answer: D. 21m³
Solution:Wet Qty. of concrete = 100 Cum

To get the dry volume of concrete, generally wet volume of concrete will be multiplied by 150%.
Therefore 100 Cum * 150% = 150 Cum.
Cement Qty. = Dry volume of concrete / (Sum of the ratio values).
= 150/(1 + 2 + 4).
= 21.4 Cum of Cement.

19. Whenever the whitewashing or distempering is done on corrugated iron sheets, in the estimation the plan area of the sheets is increased by __________.

Correct Answer: D. 14%
Solution:During estimation the flat surface area of sheet is increased by 14% whenever white washing and distempering is done on corrugated iron sheets.

Corrugated surfaces shall be measured flat as fixed and not girthed. Quantities so measured shall be increased by the following percentages and the resultant shall be included in general areas:

(a) Corrugated steel sheets : 14%

(b) Corrugated asbestos cement sheets : 20%

(c) Semi-corrugated asbestos cement sheets : 10%

20. When actual cost of construction plus certain profit is paid to the contractor, such a contract is known as __________.

Correct Answer: C. Cost plus percentage contract
Solution:A cost-plus contract, also termed as cost reimbursement contract, is a contract where a contractor is paid for all of its allowed expenses, plus additional payment to allow for a profit. Cost-reimbursement contracts contrast with fixed-price contract, in which the contractor is paid a negotiated amount regardless of incurred expenses.

There are four general types of cost-reimbursement contracts, all of which pay every allowable, allocatable, and reasonable cost incurred by the contractor, plus a fee or profit which differs by contract type.

Cost plus fixed-fee (CPFF) contracts pay a pre-determined fee that was agreed upon at the time of contract formation.

Cost-plus-incentive fee (CPIF) contracts have a larger fee awarded for contracts which meet or exceed performance targets, including any cost savings.

Cost-plus-award fee (CPAF) contracts pay a fee based upon the contractor's work performance. In some contracts, the fee is determined subjectively by an award fee board whereas in others the fee is based upon objective performance metrics. An aircraft development contract, for example, may pay award fees if the contractor achieves certain speed, range, or payload capacity goals.

Cost plus percentage of cost pay a fee that rises as the contractor's cost rise. Because this contract type provides no incentive for the contractor to control costs, it is rarely utilized.
