1. The construction phase of a building project is at the end of its 6th month, while its total duration was estimated to be 12 months. At the beginning of the project, the progress was estimated to be as follows: Month: 1 Scope: 3% 2 4% 3 6% 4 7% 5 10% 6 12% 7 13% 8 13% 9 10% 10 9% 11 7% 12 6% The following tables show estimations of the trades and material required to complete the project, plus the person-hours spent and the material consumed at the end of the 6th month: Rate ($/hr) Trade Type Concrete & Masonry Painting & Finishes Glass & Glazing Floor Covering Communications Plumbing Metal Fabrication & Millwork Drywall & Acoustics Electrical Mechanical & HVAC Person- hours 1000 500 800 2000 1500 1000 2400 4000 1400 1200 40 50 55 55 90 70 65 70 75 85 Spent (%) 84 3 12 91 22 69 59 79 38 68 Material Concrete, Rebar & Masonry Paint Glass Cable Pipe Wood HVAC Units Mechanical Equipment Price ($) 300,000 70,000 27,000 40,000 35,000 25,000 124,000 32,000 Consumed (%) 88 4 6 96 23 61 10 52 According to the eamed value analysis, 48% of the scope is completed at the end of the six months. During the first six months of the project, the price of pipe and paint were escalated by $5250. Further, half of the mechanical equipment was purchased at a 20% additional price because of inflation. At the end of the 4th month, a change order was issued and approved, which increased the total plumbing person-hours by 10%. The second change order was issued (yet to be approved) at the end of the 5in month that could increase the total floor covering workload by 20%. The third change order was issued and approved at the end of the 6th month, which adds an extra $10,000 to the metal fabrication & millwork. The rate of Drywall Acoustics and the price of all materials except pipe and paint will be escalated by 10% after the 6th month. Calculate the following items and show them (schematically if necessary) on a diagram: a. Original BAC b. Updated BAC at the end of the 6th month c. BCWS d. BCWP e. ACWP f. CV g. CPI h. SV i. SPI j. EAC (Cost) considering the same rate of progress 2. Based on all actual numbers at the end of month 6, extrapolate or project to the end of month 7 (75 month) what you believe will have been spent or consumed by then and re-calculate all EV values from above. Explain why you believe your new numbers should be credible. 1. The construction phase of a building project is at the end of its 6th month, while its total duration was estimated to be 12 months.
