Earned Value Management (EVM) is a project cost control method that can be used to measure productivity. The objective of this assignment is to learn how EVM calculations are performed.

1. The construction phase of a building project is at the end of its 6^th 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 2 3 4 5 6 7 8 9 10 11 12

Scope: 3% 4% 6% 7% 10% 12% 13% 13% 10% 9% 7% 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:

Trade Type	Person-hours	Rate ($/hr)	Spent (%)
Concrete & Masonry	1000	40	84
Painting & Finishes	500	50	3
Glass & Glazing	800	55	12
Floor Covering	2000	55	91
Communications	1500	90	22
Plumbing	1000	70	69
Metal Fabrication & Millwork	2400	65	59
Drywall & Acoustics	4000	70	79
Electrical	1400	75	38
Mechanical & HVAC	1200	85	68

Material	Price ($)	Consumed (%)
Concrete, Rebar & Masonry	300,000	88
Paint	70,000	4
Glass	27,000	6
Cable	40,000	96
Pipe	35,000	23
Wood	25,000	61
HVAC Units	124,000	10
Mechanical Equipment	32,000	52

According to the earned 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 5^th month that could increase the total floor covering workload by 20%. The third change order was issued and approved at the end of the 6^th 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 6^th month. Calculate the following items and show them (schematically if necessary) on a diagram:

1. Original BAC
2. Updated BAC at the end of the 6^th month
3. BCWS
4. BCWP
5. ACWP
6. CV
7. CPI
8. SV
9. SPI
10. 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 (7^th 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.
