What are the possible hazard and risk that may affect the construction?

How do you come with the budgetary cost for convenience outlet?

Why concrete mix proportions need to be designed? After completing the design mix process, explain what are the next steps to be done? If the same concrete mix proportions calculated in (a) is to be used for application near marine environment or in heavy industrial area, suggest with justification the possible modification that can be done.

A six-lane freeway with three lanes in each direction has regular weekday users. The

lanes are 12 feet wide, the right-side shoulder is 2 ft wide, and there are two ramps

within 3 miles upstream and two ramps within 3 miles downstream of the segment

midpoint. The highway is on rolling terrain with 12% large trucks and buses and 2%

recreational vehicles. The peak hour factor is 0.85. Determine the maximum hourly

volumes that can be sustained at LOS C and LOS D densities.

epxplain the use of no-destructive testing techniques applied to plain line and outlined the defects that can occur following track maintenance

Construction Safety

1. Corporate safety plans, site specific safety plans, and emergency response plans are very long and detailed. Employees are usually trained in the application of these plans but what happens to workers and the company if an employee with duties in these plans does not remember something they are responsible to do in the plans when an accident or emergency happens? Please write a comprehensive answer including 1) possible reasons what went wrong, 2) what can be the consequences and 3) how it should be avoided in future (one page long).

Give a step by step description of the physics and mathematics needed to calculate the trajectory of a water bottle rocket. In addition, if the location of the landing of a water bottle rocket could be controlled, what is the physics and mathematics needed to establish control?

A single crystal of a metal that has the FCC crystal structure is oriented such that a tensile stress is applied parallel to the [110] direction. The critical resolved shear stress for this material is 1.75 MPa.

1) Calculate the magnitude of applied stress necessary to cause slip to occur on the (111) plane in the (1-10) direction.

2) Calculate the magnitude of applied stress necessary to cause slip to occur on the (111) plane in the (10-1)direction.

3) Which of these two slip systems is the most favourably oriented (which system will see first plastic deformation)?

a) What is insoluble residue (IR) of cement? b) What is its cause? c) The IR of portland fly ash composite cement is considerably higher than of ordinary portland cement produced from the same clinker. Why?
