Content ▪ Importance of machineries in construction ▪ Classification of Construction Equipment ▪ Plants & Equipment used in construction ▪ Factors affecting selection of construction equipment ▪ Financial aspects related to construction equipments ▪ Discounted present worth analysis ▪ Depreciation ▪ Cost of owning and operating construction equipment ▪ Economic life of construction equipment ▪ Equipment replacement policy
  3. 3. The importance of machineries for construction ▪ Work can be completed fast. ▪ Cost of project is reduced. ▪ Less number of laborers required. ▪ Excavation work can be carried out rapidly by using Power shovel, Dragline etc. ▪ Output is higher ▪ Transportation of construction materials can be done easily by using Trucks, Wagons, Dumpers etc. ▪ Heavy loads can be lifted with the help of Tower crane, Elevator etc.
  4. 4. The importance of machineries for construction (contd.) ▪ Better quality in construction is obtained by using construction equipments. ▪ E.g.: canal lining, concrete spreading, compaction & finishing are carried out by lining machine. ▪ Finishing & rolling of bituminous roads is not possible without Rollers.

  35. 35. Financial aspects related to construction equipments ▪ How to arrange finance Sources of equipment ▪ Whether to buy or hire Long term Short term Buy Down payment On loans mobilized Lease Payment in installments Time lease Leasing with option to buy later
  36. 36. Direct purchase Advantages Disadvantages ▪ Equipment is always economically operated ▪ If equipment becomes obsolete, it is useless ▪ It receives better care & maintenance ▪ Large sums involved remain blocked ▪ It can be available and used at any time ▪ Tendency to perform work as per available equipment ▪ Disposal is difficult ▪ Equipment may be used beyond its economic life ▪ Equipment may remain in idle condition for some time
  37. 37. Hiring (advantages) ▪ Little care is required for maintenance and storage ▪ Desired equipment is available in working order at short notice ▪ Investment costs can be diverted to other better purposes ▪ No fear of obsolescence of equipment, full advantage is taken by contractor of the improved technical aspects of equipment ▪ If found useful, equipment can be bought later
  38. 38. Examples- Purchase/ Hire ▪ The original cost of bulldozer power shovel is Rs. 4 lacs & its salvage value is 8% of the original cost. The bulldozer is use for 1200 hours/year and its life is 4 years. The hiring charges for the bulldozer incl. maintenance & repairs is Rs. 20000/month. Suggest whether the bulldozer should be purchased or hired. Solution: (on the board)
  39. 39. Discounted Present Worth Analysis ▪ It involves calculating the present value of all amounts involved in all the alternatives to determine the present worth of the proposed alternatives. ▪ Decision problems may be of two types: a. Revenue dominated cash flow diagram b. Cost dominated cash flow diagram
  40. 40. What is Inflow and Outflow:
  41. 41. (a) Revenue Profit dominated cash flow diagram: ▪ In this type of cash flow diagram, the revenue, profit, salvage value, etc. (inflows) will be assigned a (+ve) sign while costs (outflows) will be assigned. ▪ Finally, the alternative having the maximum present worth amount should be selected as the best alternative.
  42. 42. (b) Cost dominated cash flow diagram: ▪ In this type of diagram, the cost(outflows) will be assigned with (+ve) sign and revenue, profit, salvage value(all inflows) etc. will be assigned with (-ve) sign. ▪ Finally, the alternative having the minimum present worth amount should be selected as the best alternative.
  43. 43. Depreciation ▪ It is the gradual loss in the value of the property due to its use, life, wear, tear and decay. ▪ It is dependent on its original condition, quality of maintenance & mode of use. ▪ Usually a % of depreciation per annum is allowed, which gradually increases with time ▪ Present value of property = Initial cost - Total amount of depreciation
  44. 44. Types of depreciation a) Physical depreciation 1. wear and tear from operation 2. action of time and other elements b) Functional depreciation 1. inadequacy or suppression 2. obsolescence
  45. 45. Methods of Calculating Depreciation: 1. Straight Line method 2. Constant Percentage method 3. Sinking Fund method 4. Sum of Digits method 5. Service Output method
  46. 46. Straight Line method Assumption: Property loses its value by the same amount every year. Therefore, Annual Depreciation= Annual Decrease in property value where, D= Annual Depreciation C= Original Cost Depreciation of property after m years: S= Scrap Value n , m= life in years Therefore, Book value after m years:
  47. 47. Constant Percentage method ▪ Assumption: Property will lose its value by a constant percentage of its value at the beginning of every year. Where, p= % rate of annual Depreciation S= Scrap value C= Original cost n= life in years ▪ If any age of property is m years, the value of property after m years:
  48. 48. Sinking Fund method ▪ Assumption: depreciation of the property = the annual sinking fund + interest on the sinking fund for that year ▪ If I is the rate of interest, the annual sinking fund installment(p) to accumulate 1 Rs in m years: ▪ If I is the rate of interest, and 1 Rs is deposited every year, total sinking fund accumulated at the end of n years: ▪ Rate of depreciation in n years:
  49. 49. Factors affecting Cost of Owning & operating Equipment: ▪ Cost of the equipment to the owner ▪ Demand of the equipment at the end of its useful life ▪ Number of hours it is used per year ▪ Number of years it is used ▪ Severity of conditions under which it is used ▪ State of maintenance and repairs
  50. 50. Costs to be considered for owning and operating equipment: ▪ Depreciation Cost ▪ Investment Cost (Average investment= ) ▪ Maintenance and repair Cost ▪ Operation Cost (Repair charges, Depreciation on tyres and tubes, Labour Charges, Fuel Charges, Operators and maintenance crew charges, Miscellaneous Supplies) ▪ Down time Cost ▪ Obsolescence Cost ▪ Replacement Costs
  51. 51. Numerical For construction Equipment following information is available. Initial cost of acquisition = Rs 6500000 Cost of tyre sets = Rs 350000, replaced after every 4500 hours Cost of lubricants, minor Repairs and maintenance = Rs 1100/hour Estimated life = 13500 hours of operation Estimated salvage value = 15% of initial cost Estimated usage of equipment= 1500 hours/year If MARR is 20% per year, Estimate minimum hourly rental charges for equipment
  52. 52. Economic life of Construction Equipments: Equipment should be replaced under following circumstances: 1. Depreciation 2. Downtime 3. Inadequacy 4. Normal Deterioration
  53. 53. Equipment Replacement Policy: A firm has to face three type of decisions: 1. The replacement of equipment as it wears out 2. The equipment required for expansion 3. The replacement of old technology by new Equipment is replaced before its estimated life to: ▪ Reduce production cost ▪ Reduce fatigue ▪ Raise quality ▪ Increase output ▪ Secure greater convenience, safety and reliability
  54. 54. What not to consider while selecting an equipment: For Equipment in Use ▪ Original Cost ▪ Money already spent on repairs and maintenance ▪ Unrealistic book value For New Equipment ▪ Any savings not clearly assessable ▪ Overhead charges
  55. 55. Thank you
