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.

What are the main differences between driven piles and drilled shafts in soil? Explain in terms of their construction, installation process, and load-bearing capacity. (Refer to chapter 13 of the textbook)

Estimate the actual bucket load in bank measure for a shovel bucket whose capacity is 3.0 m³. The soil's bucket fill factor is 0.80 and the load factor is 0.70.

Please answer only if sure! will thumbs up if correct.

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

Q5/ Determine the bit size needed for drilling to the depth of the surface casing of a well if the casing program calls for a surface string, an intermediate string, and a 5.5-in. production string.

Estimate the hourly production in bank measures of a hydraulic shovel loading sand and gravel into trucks. The machine is equipped with a front dump bucket having a heaped bucket capacity of 5.2 Lm³. Average swing angle is 60 degrees. The bucket fill factor is 0.9, job efficiency is 1.0, and load factor is 0.85.
