During an investigation of a bridge collapse, Engineer A investigates another similar bridge, and finds it to be only marginally safe. He contacts the governmental agency responsible for the bridge and informs them of his concern for the safety of the structure. He is told that agency is aware of this situation and has planned to provide in next year’s budget for its repair. Until then, the bridge must remain open to traffic. Without this bridge, emergency vehicles such as police and fire apparatus would have to use an alternate route that would increase their response time by approximately twenty minutes. Engineer A is thanked for his concern and asked to say nothing about the condition of the bridge. The agency is confident that the bridge will be safe. Analyse the case using the six steps with the perspective of Engineer A

Using Internet resources, watch a few video clips on the Minnesota I35 bridgecollapse on August 1, 2007, read material online about the collapse, and tryto understand the reasons behind the failure of the bridge. Investigate if thefailure was brittle or ductile overall.
a) The Highland Tower Block 1 collapsed due to major landslide on 11 December 1993 in Taman Hillview, Ulu Klang, Selangor, Malaysia. The collapse of Block 1 resulted in 48 deaths. Residents of the other two blocks and neighbouring establishments were evacuated due to safety concerns. Discuss briefly the causes of the tragedy and the methods to prevent this from happening. b) Jabatan Kerja Raya (JKR) intent to upgrade the road from Rawang to Bestari Jaya. A cut slope has been proposed to widen the existing road as shown in Figure Q3. Based on the JKR requirement, Factor of Safety (FS) for the cut slope should be more than 1.3. Check whether the FS for proposed cut slope meet the JKR requirement. Suggest the solution if the FS not meet. Cutting area y = 19.0 kN/m c'= 12 kN/m? 6m 60° Ø'= 20° Figure Q3: Cross Section for the Proposed Cut Slope
Engineers are designing a new bridge to replace a 100-year-old bridge that has fallen into disrepair due to increased traffic and weathering. Describe a consideration that a computer model could help engineers analyze in order to develop the design. Describe one possible criterion and one possible constraint of the design of the new bridge.
Discuss the concept of pipeline hazards and their impact on pipeline efficiency.
b. Answer the following: 1. When you know that 4 persons use the walkway side by side, what the width of that walkway has to be? 2. What is the main characteristic that has to be good enough to avoid head on crashes? 3. Which level of service that has a forced flow?
Identify and briefly discuss at least 3 risks that may be associated with this project. Highway 410/Steeles Road Project- Highway 410 currently has 4 lanes of traffic in each direction, i.e., northbound and southbound, with a 12-ft median between the northbound and southbound lanes- Steeles Road has 3 lanes of traffic in each direction, i.e., eastbound and westbound, with 4-ft median between the eastbound and westbound lanes- For this project the requirement is to: Build two off-ramps from Highway 410 to Steeles Road to, i.e., eastbound and westbound ramps Build two on-ramps from Steeles Road to Highway 410, i.e., northbound and southbound ramps Build a bridge overpass on Highway 410 over Steeles Road
Three designs have been proposed to improve traffic flow at a major intersection in a heavily traveled suburban area. The first alternative involves improved traffic signaling. The second alternative includes traffic-signal improvements and intersection widening for exclusive left turns. The third alternative includes extensive reconstruction, including a grade separation structure. The construction costs, as well as annual maintenance and user costs, are listed in the following table for each alternative. Determine which alternative is preferred based on economic criteria if the analysis period is 20 years and the annual interest rate is 15%. Show that the result is the same using the present worth, equivalent annual cost, benefit–cost ratio, and rate-of-return methods.
