Question

(Based on Alton Bridge Video Clip) Large construction projects, like buildings and bridges, are some of the most complex projects to manage. The construction of the bridge from

Alton, Ill. to St. Louis provides an excellent example of a complex project. Describe three challenges the Alton Bridge project had faced and how they were resolved?

Answer 1

One of the three Challenges Alton Bridge project faced was when they was building the towels for the build in phase 2. Due to the wind they had to build the tower on the ground where the crew assembled the towers reinforcing steel, that was custumer fit for the different measurement for the steel bar the towers. they use crones to left the towers in the air. The poured concrete in the higher section of the tower. However the concrete failed the state quality test, the concrete was super lightweight . To resolved this issue they had to shut down the tower and had to remove 215 cubic feet of concrete. The most important things was not to rush to make up time. Due to late fall weather it was every dangerous and cause delay, so they had to finish in the early spring. The 2ndchallenge happen in phase 3 they had a crane tip over and they hit an old sunken barge while excavating. So they had they had to cut a huge steel sqare out of the old sunken barge. To resolve this costly delay they use accurate scheduling( like PERT and CPM) to save a lot of money. The 3rd challenges had in phase 6 when it rained, rain and kept on raining. It the construction site to go under water. Their was barely any work that could be done the bridge until mid September. To resolved this they required major revision and crashing to fix this. Basically shorten normal through the use of additional resources to if the cost benefit the time saved
