9. Using the base shear (V) from Question 8, distribute the seismic forces across the four stories. The story heights are: F4h F3h 112 kips 225 kips 337 kips F2h 450 kips F1h-> V *11.5'f ₤11.5'f ₤13.17 ₤11.5'

In what order are dimensions entered onto the takeoff?

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.
