The service load bending moments on a beam are 128 kip-ft for dead load and 107 kip-ft for live load. The beam is 12 in. wide, f’c is 3000 psi and fy is 60 ksi. Determine Mu, Mt, p, R, the depth of the beam and the As of tensile reinforcing required. How many no. 8 bars or No. 10 bars would have the required As?

Explain how Design-Bid-Build and Design-Build project delivery methods can differently affect on management of project changes, claims, and disputes (Max 200 words).             

What is the typical approach in the contracts to shift the project risk to the other contracting party? What are the usual consequences of this inequitable risk assignment? Provide an example of contract provisions that are typically used to shift the project risk to other parties (Max 200 words).

Q5 Before carrying out rectification being an engineer how you will do the task preparation.

what are the interior and exterior facilities required to construct an amusement park

The column of a ten-story concrete structure is considered short column and is under axial loading of 900 kips dead and 400 kips live load. Design a square column using f'c=5000 psf and fy=60000 psi. Determine vertical reinforcement and ties and draw a sketch. Follow all requirements of ACI.

The air exchange coefficient for my home has been determined to be 0.35 hr-1. My house volume is 13,757 ft3. Assume a constant house temperature of 67 F.
For the West Face Wall, Area = 693 ft^2, total R-value (or U-value) = 5.53 ft^2- F- hr / Btu.

Calculate:

[15] 1b the heat loss through the west wall for December 17 (average daily temperature was 1 °F). Note
that the HDD value needs to be multiplied by 24 (24 hrs / day) to get the daily heat flux value
since R has units in hours.

[20]1c. The energy needed to heat air for Dec 17 (average daily temperature was 1 °F).

note-please attach diagram with answer, do with easy method so I can understand question..
Q:34.6An earth canal in good condition is 17 m wide at the bottom and has side slope of 2 horizontal to
1 vertical. One side slope extends to a height of 7.8 m above the bottom level and the other side
extends to an elevation of 1.8 m, then extends flat to a distance of 150 m and rises vertically. If
the slope of the canal is 0.7 m per 1379 m, estimate the discharge in (m3/s) when the depth of water is
2.5 m. Assume Chezy's constant C = 39.

1.In towns and cities around the world,dust is one of the biggest challenges in office and residential houses especially in areas where building and people are crowded.Design a system that is safe and can reduce dust particles in rooms. (Hint
; consider electrostatic precipitators
)

2. Soil moisture content is an important aspect in agriculture. Measurements of soil moisture content can be done using capacitors. Design a soil moisture sensor and suggest how to calibrate it. (Hint; soil moisture can be considered as dielectric material)

3. Global warming is assuming temperature to rise above expected levels. Traditional building practices and materials are failing to cope up with these challenges,as a result houses are very warm during the hot season and moderately cold during cold season. Consider local building practices and building materials and propose modifications in design and construction of houses to cope with climate change.

Assume that the general contractor during the contract bidding phase notices a critical element of the wall section detail for the building is omitted. Further assume, the general contractor knows that the missing element is necessary for a successful project, required by code and will increase the cost of the project. The general contractor with knowledge of the error fails to disclose it or raise any question or request for information and bids the project believing they will be entitled to a hefty change order by raising it later. Explain how the law, ethics and morality combined with the terms of the AIA A201 General conditions should treat the General Contractor’s request for a change order for the cost of installing the missing element.

Consider a 2-acre detention basin with vertical walls. The triangular inflow hydrograph increases linearly from zero to a peak of 60 cfs at 60 min and then decreases linearly to a zero discharge at 180 min. Route the inflow hydrograph through the detention basin using the head discharge curve for the 5-ft pipe spillway in table below. The pipe is located at the bottom of the basin. Assuming the basin is initially empty, use the level pool routing procedure with 10-min time interval to determine the maximum depth in the detention basin.
