Calculate total cost per cubic yard of concrete, given the following:Concrete materials and batching costs = $70/cyTrucking = $6.00/cyPaving equipment = $370.00/hrPaving labor = $530.00/hrPaver production = 120 cy/hrIncidentals = $4.00/cyOverhead and profit = 20% of direct costs Group of answer choices $100.20 $87.5 $105.00 $107.50

Why is it recommended that the estimator begin a takeoff of concrete work by measuring the quantity of concrete in an item rather than the amount of formwork?

Prepare a typical bay estimate based on the following information: a. Bay size of 350 feet and a building perimeter of 1,100 feet. b. There are 50 bays in the building. c. Unit prices: • Concrete piles: $950.00 each • Concrete pile caps: $725.00 each • Slab-on-grade: $12.50 per sq. ft. • Structural steel frame: $4.90 per sq. ft. • Roof structure: $10.75 per sq. ft. • Roofing: $8.20 per sq. ft. • Plumbing & HVAC: $9.80 per sq. ft. • Electrical: $6.10 per sq. ft. • Exterior foundations: $100.00 per linear ft. • Exterior walls: 728.00 per linear ft.

Why is it also preferable to measure the concrete and all other work associated with an item before going on to measure the concrete in another item?
