Sustainable construction has been high on the agenda of the industry for a number of years. You have been asked to give your view on:

i. Is modern construction sustainable? You must present more than one side to a discussion of this question, finally coming to a conclusion that you support with arguments and with reference to case studies. Your case studies may range in scale and purpose.

ii. How have modern materials improved the sustainability of construction in recent years? You must include in your discussion an explanation of how this has been achieved and how successful this achievement is within the context of global sustainable development.

Which ASTM (type 1-5) cement is most appropriate for the following construction applications? What types of mineral and/or chemical admixtures could be used for each application? Give reasons for your choices: Construction of a transfer plate with a thickness of 2 metres.

Please develop at least five design notes to be provided in the construction drawing for cast-in-place reinforced concrete piles without permanent casing

a.PM2.5 is a criteria pollutant that can have immense impact to our health and visibility. It is defined using the aerodynamic diameter. But how is this diameter being defined, i.e. what is the definition of aerodynamic diameter?

b. Why is PM2.5 defined using aerodynamic diameter?

c. What is the physical meaning of relaxation time of an atmospheric particle? And explain how the relaxation time is associated with the size of the particles.

d. Impactor and cyclone are commonly used size-selection devices to separate PM2.5 particles from the particle-laden air. Describe with sketches by hands to illustrate how the separation is achieved with the impactor. Please define relaxation time and explain how the particles separated with an impactor using the relaxation time concept. Be reminded to label the sketches clearly.

Assume you are conducting a parking study in your University. You need to explain the processes/tasks that you will undertake to complete this study. You need to explain how you will do different tasks and how you will present the collected data.

A vertical summit curve has its highest point of the curve at a distance 48 m from the P.V.T. The back tangent has a grade of +6% and a forward grade of -4%. The curve passes thru point A on the curve at station 25+140. The elevation of the grade intersection is 100 m at station 25+160.

1. Compute the length of the curve.
2. Compute the stationing of P.V.T.
3. Compute the elevation of point A on the curve.

1. Explain the reasons why disputes and/or conflicts arise and ways of avoiding them on construction projects?

2. What are the benefits of Alternative Dispute Resolution you can suggest to your Client with clear examples?

3. What are the advantages and disadvantages of negotiation you found when choosing negotiation as an alternative despite the resolution method?

Assume that a two-lane small road crosses a two-lane main road at a right angle making a four-leg intersection where the traffic on the small road controlled by a yield sign. A shopping mall is located 108.24 ft from the centerline of the outside lane of the main road and 12 m from the centerline of the nearest lane of the minor road. Determine the maximum velocity (in km/h) that can be allowed on the small road if the speed limit on the main road is 39.77 mph. Grades of both the roads are leveled.

Q9. A Waste water treatment units is proposed to be designed for the Wilayat of Sur. Population of Sur is 200,000 and an average sewage generation is 210 liter per capita per day. Design an appropriate waste water treatment plant using the following given data. If needed assume other necessary data.

Approach channel velocity = 42 m/min, d = 1.5 w Design three aerated grit chamber Detention time in grit chamber = 3 min Depth of aerated grit chamber = 2.0 m Depth to width ratio in aerated grit chamber is 1:1.2 Total depth of primary clarifier = 3 m (Mechanical Sludge removal) Overflow rate = 20 m3/m2.d Detention time in the primary clarifier should be greater than 1.5 hours Secondary clarifier with a depth of water equal to 0.5 times the Length (Mechanical Sludge removal) Detention time in secondary clarifier = 2 hours

a. List and explain briefly the important parameters to be analyzed for the waste water before and after treatment. (2)

b. Is waste water treatment is compulsory before disposing it to the land? Justify. (2)

c. What is meant by sludge? Is sludge resource or waste? Explain. (2)

d. Why is the aeration tank followed by primary sedimentation process? (2)

e. Design (size of the unit) the following units of the treatment process: Rectangular Bar screen channel, Rectangular Aerated Grit chamber, Six Circular Primary Clarifier, and Six Square Secondary Sedimentation tank.   

Identify and describe a primary building material used for the construction of a single story commercial building. Why would this material be selected over the other primary materials we discussed this semester?(Wood, Concrete, and steel)

Items of importance in your discussion include:

-relative cost for this project to other materials for this kind of project

-material handling and assembly

-methods available to speed up material assembly time on site

Sir,
Matlab code for thick cylinder lined with composite which is related to Mechanics.

The design of shallow foundation is governed by the bearing capacity of soil. The bearing capacity of soil is the maximum average contact pressure between the foundation and the soil which should not produce shear failure in the soil. However, some cases at site, the suitable bearing capacity only can be found at 3 m depth from the surface or more. Based on your understanding, discuss this situation and how to resolve the issue in perspective as a consultant engineer

A horizontal pipe has an abrupt expansion from D₁ = 8 cm to D₂ = 16 cm. The water velocity in the smaller section is 6 m/s and the flow is turbulent. The pressure in the smaller section is P₁ = 418 kPa. Determine the downstream pressure P₂ in kPa.
