Q11.a. Calculate the cost of a foundation with length x width x
thickness dimensions of 1000 x 1200 x 600 mm. Concrete of ratios
1:4:8 will be made and mixed at site with a mixer machine. Assume
the following: [8.5]
• The manpower service rate for casting the concrete OMR 13 / cubic
meter.
• The formwork rate is OMR 5 OMR / square meter.
• The diesel consumption for the mixer machine is 3 liters /
hour.
• The diesel machine needs to work for 4 hours to mix concrete for
one foundation.
• The average price of diesel is OMR 0.277 / liter.
• The share of the rent of the mixer machine is OMR 6.500 for one
foundation.
• Steel is to be excluded from this calculation.
• Prices for the raw materials are as follows:
o Cement: OMR 1.700 / bag
o Sand: OMR 15 / cubic meter
