Oliver Owner wishes to build an office building. Oliver hired Original Architect, Inc. to create the design. Over several months, Original Architect, Inc. gave Oliver several drafts of increasing detail. Uninspired by what he saw, Oliver terminated its contract with Original Architect, Inc. and hired Replacement Architect, Inc. in its place. Oliver gave Replacement Architect, Inc. the last drawing Oliver had received from Original Architect, Inc. Replacement Architect, Inc. used this last drawing to create its own final design. Oliver then hired Prime Builder, Inc. to be the prime contractor on the job. The contract price was for a fixed amount, with work to be completed in one year. The project did not go smoothly. Oliver failed to obtain a zoning change on time, and work had to begin one month late. Meanwhile, Prime Builder, Inc. found the design literally impossible to implement; for example, all of the specified conduits would not fit into the space allotted, forcing Replacement Architect, Inc. to redesign. This took Replacement Architect, Inc. two weeks to do. Meanwhile, Replacement Architect, Inc. was unhappy with the quality of the contractor’s work. Within a week after the foundation was poured, it began to crack. Replacement Architect, Inc. determined the soil preparation work was not properly done. It ordered Prime Builder, Inc. to remove the foundation and redo the soil preparation, which the contractor did. The project was finished three months late. As a result, several commercial tenants who had promised to move into the new building found rentals elsewhere. Overwhelmed with all the problems on the construction project, Oliver did not even try to find replacement tenants until two months after the building was completed. Eventually, Oliver fully rented the building.

Task 1:

a)  Assume the mix is made with Type I cement, with no pozzolans or admixtures, and that the temperature of concrete at placing is 75°F. The unit weight of concrete is 150 pcf with a slump of 3.75 inches.

Design forms for 13’-8” high wall to be concreted at the rate of 6 ft per hour, internally vibrated. The forms will be used only once, so short-term loading stresses will apply.

Use form grade plywood sheathing 7/8 in. thick in 5×10-ft sheets, and 5,250-lb coil ties are on hand Framing lumber of No. 2 Douglas Fir-Larch is to be purchased as required.

b) Draw the pressure diagram for a wall form 15 feet tall in which concrete will be placed at a rate R = 10 feet per hour when the temperature is 60oF. Draw the diagram if the wall were only 6 feet tall.

How do you calculate the overturning moment for each story of the building in Excel. Suppose we have a 5 story building that is 50 feet tall and each floor is 10 foot high. The force on the 5th floor is 10 kips, on the 4th floor it's 8 kips, on the 3rd floor it's 6 kips, on the 2nd floor it's 4 kips and on the first floor it's 2 kips. Is there a routine you can use in Excel that will calculate this without much effort.

How do you calculate the overturning moment for each story of the building in Excel. Suppose we have a 5 story building that is 50 feet tall and each floor is 10 foot high. The force on the 5th floor is 10 kips, on the 4th floor it's 8 kips, on the 3rd floor it's 6 kips, on the 2nd floor it's 4 kips and on the first floor it's 2 kips. Is there a routine you can use in Excel that will calculate this without much effort. The fourth floor will have an overturning moment of 10*10=100; the third floor will have an overturning moment of 10*20+8*10=280; the second floor overturning moment is 10*30+8*20+6*10=520; the first floor's overturning moment is 10*40+8*30+6*20+4*10=800; the base overturning moment is 10*50+8*40+6*30+4*20+2*10=1100

- A strip footing is founded on sand having strength parameters (Φ =40⁰ and c = 0 kPa). Dry and saturated unit weights of the soil are 17.8 and 21 kN/m³ respectively. The foundation is designed to to carry a load of 4.8MN/m at a Factor of safety against general shear failure of 3. The footing depth is 1.5 m and the water table is 5 m from the surface.

a) Determine the minimum footing width (m) to satisfy the design requirements (2 d.p). Show all working

b) Is water table affecting foundation support?

c) Is water table affecting foundation support? Verify your assumption. Use unit weight of water of 9.8 kN/m3.
