A construction project consists of 5 similar buildings, it is required to excavate 4200 m3 for foundations for each building. If the contractor has 5 excavators, and the productivity of each excavator is 17 m3/hour. assume that the number of working hours per day is 7 Note: put your answer up to 2 decimal places. Estimate the following requirements: Manhours for the excavation activity? Mandays for the excavation activity? Duration for the excavation activity? "days" If the number of excavators is increased by two, estimate the new Duration for the excavation activity? "days"

A constructor has two subcontractors for his excavation work. Experience shows that in 60% of the time, subcontructor was available to do a job, whereas subcontractor B was available 80% of the time. Suppose Ea denotes the event that subcontractor A is available, ans Eb denotes that subcontractor B is available.a. Are Ea and Eb statistically independent? Explainb.Are Ea and Eb mutually exhaustive? Explainc.Are Ea and Eb collectively exhaustive? Explain
A project to move packed earth requires you to decide whether to use a dozer/scraper operation or excavator/truck operation. Determine the most economical operation based on the dozer/scraper operation estimated at $1.25/cy. All equipment carries a rated heaped capacity, has a fill factor of 100%, and works 45-min hours. Excavator costs $95/hr (including operator), cycle time is 0.28 min, and bucket heaped capacity is 5.0 cy. Truck costs $150/hr (including operator), dump time is 0.5 min (maneuver, dump, turn), heaped capacity is 31.7 cy, and 12 trucks are available for the project. Hauling equipment operates in one direction from A to B to C and finally to D. Section ABCD Load full full empty empty Length (ft) 3,000 2,500 3,000 3,000 Speed (mph) 9 17 36 16

Calculate the cost per cu.m. to excavate trench if the volume to be excavated is 25 cu.m., using a 0.25 m3 bucket excavator Php 3,500.00 per hour including equipment operator and consumables. The output for a 0.25 m3 bucket excavator is 5 m3 per hour. One (1) spotter is also needed on site to guide the equipment with a labor rate of Php 101.50 per hour. Consider a 20% Contractor's Profit and 10% overhead cost for this activity. a. Php 936.30 / cu.m. b. Php 1,872.78/ cu.m. c. Php 3,662.40 / cu.m. d. Php 4,576.39 / cu.m.

Let having all the expenditure, Rs 100 be the cost/hr of a shovel with volume 10 m³ which will be used to excavate dry gravel having ideal depth as 40% of ultimate depth. Find the cost per m³ under the following situation: 1. Bucket fill factor = 99 % 2. Ultimate excavating depth = 50 m 3. Angle of swing = 120 degree 4. Average Height of excavation = 28 m 5. Efficiency factor = 60 min/hr 6. Total cycle time = 30 sec
