1. You have a 5 acre commercial development, where flow drains into a gutter. Assume that the travel time is 15 mins. The rainfall intensity can be determined by the following equation: i=10t^-0.4.

For the curb and gutter have the following design parameters: n = 0.015, cross slope of 40:1 and longitudinal slope is 3.0%.

1. Determine the gutter flow depth, curb design depth and spread necessary to contain the 10 year peak flow.
2. Determine the size of the catch basin for both submerged and unsubmerged flow conditions.

1. Determine the area of the watershed, which drains to a road with a curb and gutter. The roadway information is as following: spread of flow is 10 feet, roughness is 0.013, longitudinal slope is 0.008, cross slope is 30 and curb height is 5 inches. The runoff coefficient time the rainfall intensity is 5.5 inches/hr.
   1. Find the Flowrate in the road?
   2. Determine the area of the watershed?

in a table format do a

1. Checklist for inspecting steel reinforcement and electric works of slabs (right before pouring)
2. Checklist for inspecting formwork of slabs (from above)

22a.        What would be the peak runoff rate by the NRCS Soil-Cover-Complex method for a 100 year return period for a watershed in coastal South Carolina with the following practices? Use the NRCS curve number method to find the time of concentration.

Eighty five percent of the bits used in deep rock marble drilling endure rock resistance and 95% survive after the exposure to drilling. 80% can be pressure treated to go for one shift or more of drilling and only 10% of those which are not can be used for one shift or more. a) Draw the reliability chart of these drill bits b) What is the likelihood that a bit would last one or more lap?

Answer the following questions from Civil Engineering Licensure Examination

a. CE Board May 2007
A 300 mm concrete wall supports a dead load of 300 KN/m and a live load 0f 220 KN. The allowable
bearing pressure is 240 KN/m2 and the level of the footing is 1.2 m below the ground surface. Assume
concrete weighs 24 KN/m3 and that of soil is 16 KN/m3, fc’ = 28 Mpa, fy =248 Mpa. Use 28 mmθ
reinforcing bars. Thickness of footing = 600 mm, steel covering 100 mm. Determine the spacing of bars
at critical section.

b. CE Board May 2012
A 450 mm square interior column carries a dead load of 825 KN and a live load of 668 KN. A
rectangular footing is required to carry the column loads such that the length of the long side must be
equal to twice the width of the short side. Assume base of footing is 1.5 m below the ground surface.
Allowable bearing pressure of soil is 15.74 KN/m3 and that of concrete is 23.5 KN/m3. Use normal
weight concrete. Thickness of footing is 0.60 m. Determine the steel requirements in the short and
long direction

Identify any one busy street on your community with large volumes of surface traffic comprised of vehicles, cyclists, and pedestrians. Then answer the following questions

1. Explain how you would carry out problem identification, and if a problem is found to exist, discuss how you would assess the need for a solution.

2. From the assessment you made above (in a), assume that you have established the need for a solution and that you have decided to produce a conceptual design to solve the problem. List and discuss any five conceptual design alternatives.

3. from (b) above, how would you

i). establish the goals and objectives;

ii). the criteria to assess the desirability, efficiency, or effectiveness of each design alternative; and

iii)choose the best of the conceptual design alternatives.
