A customer (homeowner) hires a contractor to tile five identical rooms in his home. The customer purchased the tiles, and the contractor will be reimbursed for labour only. Because the tiles are difficult to work with, the contractor assumes two days per room at eight hours per day and at R100 per hour. The planned cost is R8,000 but overtime will also be paid, if necessary, at the same rate of R100 per hour. The first room was completed in three days because of difficulty in workmanship and getting an understanding of how to use these special tiles. This included two hours of overtime. The second room was completed in two days. Using EVMS, the following information would be presented to the homeowner at the end of the first week. (12)

PV = 5 800 = R4,000

EV = 4 800 = R3,200

AC = 42 100 = R4,200

BAC = R8,000

SV = EV PV = R800

CV = EV AC = R1,000

EAC = (AC/EV) BAC = R10,500

VAC = BAC EAC = R2,500

ETC = EAC BAC = R6,300

Percent complete = EV/BAC = 40%

SPI = EV/PV = 0.8

CPI = EV/AC = 0.76

Now it is your turn. Having tiled the floors, you now hire a contractor to wallpaper all of the walls in each of the five rooms. Once again, you purchase the wallpaper and will reimburse the contractor just for labour. The contractor works at R100 per hour and estimates eight hours of work per room, for a total of five days. At the end of the first week, working eight hours per day, the contractor completed only three rooms.

The EVMS status is: a. PV = b.

EV = c.

AC = d.

BAC = e.

SV = f.

CV = g.

EAC = h.

VAC = i.

ETC = j.

Percent complete = k.

SPI = l.
