A project involves excavation of a 30m by 30m raft foundation to a depth of 2m, with the earth to be transported up to 30m from the edge within 15 days.

Estimate the total cost for excavation considering Manual operation and the following;

Man hours/unit: 2 hours/unit

Assume 8 hour/day of work

Cost of labor/day: $150

2. Estimate the total cost for excavation considering Mechanical Operations with one excavators and 2 tippers and the following;

2 operators per excavator and 2 operators per truck

Productivity of equipment: 30 m3/hour

Assume 8 hour/day of work

Cost of excavator/day: $3000

Cost of tipper/day: $1500

Cost of labor/day: $150

A 4.5m4.5m foundation carries a load of 3000 kN. The foundation rests at a depth of 1.5m below the ground surface. The bearing soil is an extended sand with a saturated unit weight (γsat) of 19 kN/m3 , modulus of elasticity (E) of 35 MPa, and Poisson’s ratio (µ) of 0.3. The water level coincides with the ground surface. a) Determine the effective vertical stresses (σ̍v) for points underneath the corner and center of the foundation and located at a...

A corner of a five-story commercial building resting on a raft foundation settled down a few inches in the last few years of its construction due to a pocket of loose soil underneath. As a result of undesirable settlement, the usage of building was affected, and the owner seeks the help of a consultant to suggest the proper method of underpinning to avoid any further settlement. Soil investigation reports showed that the hard rock stratum is available at a depth...

An irrigation canal with trapezoidal cross-section has the following elements: bottom width = 2m, depth of water = 0.9m, side slope 1.5H to 1V, slope of canal bed = 0.001, n = 0.025. The canal will serve clay-loam rice land. What is the hydraulic radius in meters? What is the mean velocity in m/s? If the canal will serve a clay-load rice land, determine the area in hectares it can serve if the duty of water per hectare is 3L/s.
