Curve 2: A +7.00% grade meets a -6.00% grade at station 4+80 and elevation 705.70 ft, 80-ft curve, staked 10ft apart. Get a rough estimate in cubic yards of how much soil that must be brought in (fill) and/or removed (cut) to create a 14-foot wide roadway that starts at your PVC/BVC, ends at your PVT/EVC, and follows your curve elevations. Make sure to state which curve your group was assigned in the calculations. Trapezoidal Area Estimation is key. ground has the following elevations starting from the PC and ending at the PT; 702ft, 703ft, 704ft, 705ft, 706ft, 705ft, 704ft, 703ft,and 702ft.

Mr. Paul has been working as a mechanical engineer in a well-known oil and gas firm, Toyo Engineering, for 15 years. Toyo Engineering has been awarded with a project to design and build a ship for use in offshore installation works in Terengganu, Malaysia. Due to Mr. Paul’s excellent project management skills, the company has appointed him as the Project Manager for this particular project. As a Project Manager, Mr. Paul has to deal with various vendors who are bidding to be the potential suppliers of the various items in the to-be-built ship. He has to keep close relation with all vendors to ensure that the supply of equipment and materials are on schedule for the timely delivery of the ship. Since Mr. Paul has been working in the oil and gas field for about 15 years, it happens that some of the vendors are his friends who have been working with him previously in various projects.  

  1. Identify THREE (3) most relevant BEM codes of professional conduct applicable in this case.

  

  1. Identify TWO (2) possible ethical dilemmas that will be faced by Mr. Paul in his work as a Project Manager.

(c)       Analyze how Mr. Paul should respond and act in the ethical dilemmas that you have identified in Q1(b) above.

(d)       Outline the action to be taken by Paul in protecting his company interest while complying with BEM codes of professional conduct.

The driver of an automobile, which travels with a velocity of 110 km/h on an a 8% graded
descending section of an asphalt paved straigth highway on a rainy day, recognizes a
pedestrian crossing the street 100 meters away and applies the brake.
a) Determine whether the accident occurs or not.
b)If the driver is crashing with the pedestrian, what would be the maximum velocity to
avoid the accident ?
Given: Pavement sliding friction coefficient, f= 0,30; detection-response time, tr= 1 sec.

A concrete mix is required for reinforced concrete wave breaker at seashore where frequent mild freezing and thawing is dominant.
A specified compressive strength of 25 MPa is required at the age of 28 days, and the size of the section and reinforcement dictate using a maximum aggregate size of 19 mm.
The company had no history of testing concrete used.
The coarse aggregate meets the ASTM grading requirements. It has absorption of 2%, a BSG (D) of 2.70 and a unit weight of 1550 kg/m3. The fine aggregates have absorption of 1%, a BSG (D) of 2.7 and a fineness modulus of 2.7.
Both coarse and fine aggregates are used while dry. For each bag of cement (50 kg); calculate the number of containers of coarse and fine aggregate equivalent to required mass quantities.
The volume of each container is 20 liters; and the loose density of the coarse and fine aggregates are 1250 and 1200 kg/m3, respectively.

Case Scenario Analysis:

Managing risks in construction projects has been recognized as a very important management process in order to achieve the project objectives in terms of time, cost, quality, safety and environmental sustainability. A study aims to identify and analyze the risks associated with the development of construction projects from project stakeholder and life cycle perspectives. The study identified following risk factors.

1.Tight project schedule

2.High performance/quality expectations

3.Low management competency of subcontractors

4.Incomplete or inaccurate cost estimate

5.Lack of coordination between project team members

6.Unavailability of sufficient professionals and managers

7.Serious air pollution and noise caused by construction activities

Develop understanding on how and on what level three factors of your choice can generate risk in achieving project objectives. Finally, identify a set of measures that you as a project manager would like to plan and implement to reduce risk and ensure achievement of project objectives and contribute in business development.

Hint: Your answer should include the way the factor develop risk in the achievement of project objectives and its level. Finally, you need to develop measures or actions you would like to implement to manage and/or minimize the risk.
