Calculate the cost per cubic yard to place concrete using each of the alternatives described. The work in both cases consists of placing 140 cubic yards of concrete in footings.
a. Using a crane and bucket at a price of $225 per hour, including an operator, with a crew consisting of 6 laborers, a cement finisher, and a foreman. The concrete will be placed in 7 hours using this setup, and transportation of the crane costs $390.
b. Using a concrete pump at a price of $295 per hour, including an operator and a crew consisting of 5 laborers, a cement finisher, and a foreman. With this setup, concrete is placed in 6 hours and transportation of the pump costs $290.

You are going to use one mixer that has aservice rate of 30 services per hour. The dry-batch trucksyou use for bringing concrete to the paver have an arrivalrate of 7.5 arrivals per hour. Each truck carries 6 cubic yardsof concrete. You have a total amount of 13,500 cubic yardsof concrete to pour. You rent a truck at $15 per hour and thepaver at $60 per hour. If the job takes more than 80 hours,you pay a penalty of $140 per hour owing to delays in jobcompletion. On the basis of least cost, determine the numberof trucks you should use. Plot the cost versus the numberof trucks used.arrow_forwardcan you help me with this question? what do you think are some of the problems that using pumping for concrete work brings?arrow_forward
- Your company was hired to renovate this old grain silo. You need to compile a quote for bidding the following tasks. 1. The foundation is cracked and will need to be repoured. The silo is 40 feet in diameter, and the foundation will need to be 6 inches (.5 feet) thick. First find the volume of the foundation. Then find the cost if material is $1/cu ft and labor is a flat $300. 2. Next the walls will need to be painted barn red to the height of 100 feet (ignore the dome). One gallon covers 1000 sq ft of surface, how many gallons must be purchased? If each gallon cost $30, and labor is a flat $1500, how much is this portion of the job? 3. Last, we are instructed to fill the silo with grain. How many cu ft of grain can fit into the silo? If we charge $0.02 per cu ft, what is this portion of the job cost? 4.
