Question

3- A 50-mgpd (US) water treatment plant is proposed in 2020 for Washington. A 60-mgpd plant using the same treatment process was built in 2013 in Vancouver. Make a conceptual cost estimate based on the following information: - Poor site condition in Vancouver required an additional $3,000,000 for foundation which is not anticipated for Washington. - Assume the size exponent m-0.67 Assume inflation will persist at an average of 4% per annum. Assume the location index for Vancouver is 1.17 and 1.24 for Washington A new High pressure filter process will be added at Washington at an additional cost of $4,000,000 The construction period for the new plant will be in Winter. Assume an increase of construction cost by 12%. (15 marks)

Cost of the plant in Vancouver is not given. If needed for the calculations, the information will assist in calculating it.

Answer 1

Jolution - - Assuone Gost foor vancover plant = $ 50,000,000 Reduction of Good for foundation - $ 3,000,000 Coge - $ 17,000,000 Criven the site exponent in = o.bt. Here: cost. I plan? I C = Gost I plant 2 0; = Size of plast i Qq = Size of plant ? washington Cost of plant G: GR 50 rigid :0.67 147000000 l bo ma pd) C = $ 41,595,507.08 Infilation = 24% per annum foran 2013 to 2020. furono se 7 years ca Gilet toe) * = 4164507.08 (1* )* a = $547368419.644

Location factor for vancover=1.17 for. Washington = 1.24 : C= 5473681091644 x 1.24 = $ 58011703.89 1.17 Adding faceten cost G=(5801 703.89. + 1000000 C = $ 62011703-89. Adding winter construction cost at 12 Oversal.Gost 6 = 62011703.89 x 1 2 C = 69453108.36 Magnitude of cost is $ 69453/08, 36. please rate my Solution]
