A hydraulic excavator with a 2 cubic yard heaped capacity bucket is excavating in common earth. The depth of the excavation is 8 feet. The excavator has a maximum rated digging depth of 16 feet. The excavated material will be positioned so that the swing angle is 75 degrees. The job efficiency is 55 minutes per hour. Find the expected production per hour.
Problem Estimate the TOTAL COST needed for Excavation, Gravel Bedding, and Concreting Works (Excavation + Cement + Gravel + Sand). Do not round off your answer. Parameters to consider: No allowance or factor of waste. Use Class AA Excavation Cost = 300 pesos per sq.m. Use 40 kgs bag Cement = 300 pesos per bag 100 mm thick gravel bed (include this in estimate) Sand = 1000 pesos per per sq.m. All footings lie on gravel bed (except FTB) Gravel = 900 pesos per per sq.m. D=1.53, I=16, and J=24 givens are in meter. What to estimate: For Earthworks: • Footing and Footing Tie Beam For Concreting Works: • Footing • Footing Tie Beam • Columns Additional: • Gravel Bed (Estimate the volume needed and include the cost in the total cost) GIVEN: A= 1530 B= 330 C= 1630 D= 1.53 E= 430 F= 480 G= 280 H= 860 I= 16 J= 24
for Shovel Excavator Soil Type = dry clay -Rotation angle = 75° -State of work = average - State of management = average - Excavation height = 3.05 m Q:What is the efficency per hour? (Swelling)
2: Děšign and Analysis - make sure to show all calculations, correct units and box answers for all problems. Problem 1 : Scrapers will deliver to the project 500 lcy per hr of fill material (dry clay). A self-propelled tamping foot roller will be used to compact the fill. (Rolling width is 84 in.) The fill material will be placed in 4 inch compacted lifts. The loose lift is about 10 inches. Test strip compaction information indicates that 8 passes at 4 mph are required to obtain the required density. Assume a 55 min working hour. Q1: Calculate the roller production in CCY/hr. 22: Determine the number of rollers required to support the scraper operation.
(c) Giver the end area of cut and fill of soil as in Table Q4(c). If the material bulks after excavation about 10% and shrink 12%. Given, distance between chainage is 100 m. Draw the mass haul diagram and estimate how much excess cut or fill is required.
A 6-yd hydraulic shovel with a bottom-dump bucket is excavating common earth. The swing angle is 75 degree and job efficiency is 40 min/h. The bucket fill factor is 0.9. Estimate the shovel's hourly production in BANK measure. 604.8 BCY/h 263 BCY/h 318.5 BCY/h 483.84 BCY/h Question 2 For the same question: A 6-yd hydraulic shovel with a bottom-dump bucket is excavating common earth. The swing angle is 75 degree and job efficiency is 40 min/h. The bucket fill factor is 0.9, What is the job efficiency required to reduce the current cost per BCY by $5 if the shovel costs $5000 per hour? 1.3 0.666 0.7 1.1
Choose the lowest size and the required number of crawler hoes to excavate 828864 b-Cyd of sand & gravel in 4 months. A size one Cyd excavator (including the wage's operator) costs $80 /hr. with an increment of $5 per extra 0.5 Cyd. Depth of excavation 12 ft, Swell 25%, and efficiency 65%. Suppose the work is 8hr/day. Estimate the total expected cost.
The answer is 3830.43 LCM 6. As part of a road construction project, an excavation that is 2km long by 3m wide and 0.5m deep must be backfilled and compacted. The excavation will be backfilled with sand and gravel. What volume of (in LCM) of sand and gravel must be brought to site to complete this job?
You are a civil engineer who has been given the task to monitor the excavation of road construction, It is deemed viable that it typically takes half an hour to excavate a cubic meter of soil using a typical backhoe that applies to solls within a two- meter depth from its NGL. This parameter includes hauling, piling, and other small movements within the area bound for excavation. Given that the volume to be excavated is 36m in your specified road station using only one backhoe, determine the exact total cost for this setup if the backhoe rent costs Php1800 per hour which includes its gasoline and other daily maintenance costs. The hourly wage paid to these two workers at every end of their daily shift is taken as Php101 for the backhoe operator and Php41 for the backhoe spotter. For work-life balance, you always make sure that there are only eight working hours per day with no overtime and no work on Sundays for all your workers. Note that the total cost does not include your salary as…
