what are the measure that could have been taken to prevent the disaster.

Is the AE analysis, used to determine the project acceptability?

2. In any given construction scenario a limited number of days can be taken out of the schedule before it to shorten the schedule further. Though it is impractical to take the exercise to the theoretical limit of sho theoretical limit that prevents any further shortening of the project. What defines this theoretical limit, an the schedule when this limit is reached?

Consider the following projects: Project A has a cost of 50, uniform annual benefit of 6.1 and salvage value of 37.5; Project B has a cost of 40, uniform annual benefit of 6, and salvage value of 25; Project C has a cost of 30, uniform annual benefit of 4.85, and salvage value 25; Project D has a cost of 25, uniform annual benefit of 6.1, and salvage value of 0. Using an 8-year analysis with MARR = 8%, which project should be selected using B/C ratio analysis. Project C O Project D O Project B O Project A

On design–build projects, why is it so important that preconstruction phase job conferences be documented?

A constructor has two subcontractors for his excavation work. Experience shows that in 60% of the time, subcontructor was available to do a job, whereas subcontractor B was available 80% of the time. Suppose Ea denotes the event that subcontractor A is available, ans Eb denotes that subcontractor B is available.a. Are Ea and Eb statistically independent? Explainb.Are Ea and Eb mutually exhaustive? Explainc.Are Ea and Eb collectively exhaustive? Explain

Please answer these civil engineering Questions. 1. What is PPP and why is it becoming a more popular way of delivering infrastructure projects?  2. What are the major differences between the DBFO and BOT methods of PPPs 3. How is a DBFO project similar to a more traditional design-build project?

Describe what is the evaluation of the performance of dams that have experienced an earthquake indicates?

provides various engineering solutions, including electrical, mechanical and construction. As part of the periodic performance assessment, the company has set a multidisciplinary engineering evaluation to its employees. You have been handed over the below tasks and asked to solve them, using the scientific methods you have learnt. Task (1) You have been provided with the below schematic design of a concrete beam that might be implemented at one of the sites. Answer the following: 15 KN 20 KN KN 40 KN 16 20 Figure 1: Concrete Beam 1. Find the equivalent forces of the disturbed loads. 2. Sketch the beam showing all the applied forces (reaction and equivalent forces) and their suitable locations. 3. Apply the moment equations in the equilibrium state to find the value of the reaction forces at points A and B. 28
