Unformatted text preview: ENGR-301 Assignment 3 Assignments must be submitted ONLINE on the course website (using Moodle) Due 23:59 Thursday (28-May-2015) Check the best answer (closest to the exact answer such that the absolute value |answer given – exact answer| is minimum) for each question. 3-1 Your company intends to purchase a 400 tonne capacity injection moulding machine. A similar machine was purchased eight years ago for $89,500. The price index for heavy duty equipment in the plastics industry was 163.6 eight years ago and is 207.6 now. Estimate the current cost of the machine. ($125,000 $113,000 $108,000 $98,000) 3-2 – 3-3 Nadia, John, Saba and Kumar are working together on a project. These are the data for each: Nadia: 60 hours, overhead rate 75%, personal time 10%, $20/hr John: 80 hours, overhead rate 55%, personal time 12%, $40/hr Saba: 80 hours, overhead rate 75%, personal time 10%, $36/hr Kumar: 40 hours, overhead rate 55%, personal time 12%, $20/hr 3-2 Who has the highest direct labour costs? 3-3 Calculate the total direct labour costs (Nadia John Saba Kumar) ($14,800 $14,000 $15,100 $14,300) 3-4 – 3-6 Weldex Industries begins to manufacture a newly designed, small, spot welding machine. The labour hours required for making the second and third units are 28.6 and 28.2 hours respectively. 3-4 Calculate the labour hours required to manufacture the first unit. (28.8 29.1 29.3 29.5) 3-5 Calculate the labour hours required to manufacture the 50th unit. (29.3 27.9 25.5 23.8) 3-6 If labour costs are $18/hour, calculate the total labour costs to produce the first four machines ($1900 $1950 $2000 $2050) 3-7 – 3-10 A 50-mgpd (million gallons per day) water treatment plant was proposed in 2013 for Ureka. A 60mgpd plant using the same treatment process was built in 2007 in Vancouver for $50,000,000. Given the following additional information and assumptions: • • • • • • Poor site condition in Vancouver required an additional $3,000,000 for foundations, which is not anticipated for Ureka. Assume the power sizing size exponent = 0.67. Assume inflation will persist at an average 4% per annum. Assume the location index for Vancouver is 1.17 and 1.24 for Ureka. A new high-pressure filter process will be added at Ureka at an additional cost of $4,000,000. The construction period for the new plant will include winter construction. The Vancouver plant was not constructed through a winter season. Assume an increase in construction costs for Ureka of 12%. In order to make an order of magnitude estimate of the water treatment plant in Ureka, various multiplication factors need to be calculated. 3-7 Calculate the multiplication factor based on the different capacities (0.80 0.90 1.00 1.10) 3-8 Calculate the multiplication factor based on effect of inflation (1.37 1.22 1.42 1.27) 3-9 Calculate the multiplication factor based on the different location indexes (1.07 1.03 0.99 0.95) 3-10 Calculate the order of magnitude estimate of the water treatment in Ureka (35M 50M 65M 85M) ...
