What forces are transferred into a knee joint Connection, what suitable steel can be used for a knee joint connection?

Earth, whose load factor 0.80 is and whose shrinkage factor is 0.90 is being placed as fill. The construction schedule requires that fill material needs to be placed at a minimum rate of 600 LCY/hr. (Hint: you need to turn the LCY requirement into a CCY requirement. This is required as the production for a compactor is based on CCY.) The thickness of the compacted layers is 5.5”. A compactor with a roller drum width of 7’ is used to compact the material at a speed of 3 mph. Assume you are operating 45 minutes per hour. Determine the number of roller required to provide the necessary compaction rate if eight drum passes are specified for each layer of earth.

Outline all methods of dynamic soil property evaluation for machine foundation designs.

Describe ( in details) 5 cost control techniques used by contractors in construction projects.

Water of varying density flows in an estuary, 5 meters deep. The density varies linearly from 1025 kg/m3 at the bottom to 1000 kg/m3 at the water surface. The velocity distribution is given by the equation, V = 8 - ((1/2)(z-4)^2) m/s, where z is elevation above the bottom.

a)Sketch (or plot using software such as Excel or Matlab) the density (ρ) profile, the velocity (V) profile, and the momentum (ρ V) profile

b)Find the two values of z for which velocity equals 7.5 m/s. Does the water have the same momentum at these points? Why or why not

C)Calculate the total momentum, ∫ ρ V d ∀ , for a volume of water 5 m deep, 1 m wide, and 1 m long.

Explain the process for establishing the line and grade for a sanitary sewer line connection to an existing municipal sanitary manhole. Include the type of sewer flow, the importance of the pipe invert and reach of the sewer in determining the slope of the pipe, factors that determine the use of manholes, the use of batter boards and offset stakes, minimum ground cover required. In addition, discuss the use of visual aid such as field notes and a simple plan and profile drawing in establishing the line and grade.

The construction industry is leveraging technology to make processes more efficient. Construction companies are investing a lot of their capital in R&D to incorporate this technology into their business practices. Explore one technology (existing or future) and provide a summary of the impacts it will have on the construction industry. Below are examples you may choose from but preferably you can find a different technology if you can find one.

Examples of technology (application, software, programs):

• Navisworks
• Structuresite
• Openspace
• Bluebeam
• Revit
• Docusign

Please write a summary of the technology and should answer the following questions:

1) Company name and how long has this application/program been around?

2) What impacts does it have on the construction process (good and bad)

3) What the future looks like for these type of technology

4) your opinion on how you would implement or what improvement you see in this type of technology.

A soil has a natural water content of 10%, specific gravity of 2.65, and porosity of 0.45.

a) Find the dry unit weight and degree of saturation.

b) If the optimum water content for the soil from a standard proctor was 20%, how much water would have to be added to 1m^3 of the soil to increase the water content to an optimum level?

1. List one thing you could you change about the mixtures to increase flexural or tensile strength and briefly explain your reasoning behind why that would increase the strength.

Balance the interior angles of the traverse by applying equal corrections to each angle. If the azimuth (from north) of side EA is fixed at 169° 46', calculate the preliminary azimuths of the remaining sides. Report in D-M-S format. Interior Angles: A = 96° 05'; B = 95° 20'; C = 65° 15'; D = 216° 22'; and E = 67° 08'.

There is a tunnel (open-faced shield) in dense clayey silt soil, what are the potential problems about the construction of this tunnel??? Explain!

Thank you

1. a) Use Manning’s to determine the velocity of flow and the capacity of the following pipes:

   • 300mm PVC main installed at a slope of 3%

   • 375mm PVC main installed at a slope of 3%

   • 450mm PVC main installed at a slope of 3%

2. b) Comment on the percent increase in capacity when changing pipe to a larger size in the previous question. (You will have an answer for 300mm to 375mm and an answer for 375mm to 450mm. Your answer should be a % difference)
