Task$1.$ Read the given scenario carefully and complete the table given.

Scenario

There was a multi stories apartment building project for which a deep construction was

designed for a parking with $3-$meter height below the ground level on a raft $($Mat$)$ foundation.

Then, a $3-$meter excavation was needed to create the parking space, but it could not happen

without a proper retaining wall along the boundary, first. ABC geotechnical contractor was the

project consultant who did soil investigation and provided a geotechnical report in which the

soil properties was given. Accordingly, structural designer designed a continuous concrete wall

as the retaining wall system. This system was suitable only in a site with pure sand soil for

which a special plant and equipment were needed to excavate the site. The system included

a gap with $400$ mm wide and $6$ meters deep along the boundary that enable immediate

placing reinforcement and pouring prefabricated concrete transported to the site by concrete

mixer trucks. Pouring concrete was supposed to be followed by placing vertical $6-$meters bars

in two layers every $300$ mm$.$ The site was identified as a different soil type that contains hard

limestone impeding the special plant operation when the construction started. It was about

winter with heavy rains that caused the client to worry about heavy rain to stop the project

progress. The sub$-$structure $($below the ground level$)$ was planned to be completed before

rainy season. The operation failed after two hours of the project commencement. A high

volume of concrete was ordered, and concrete trucks gotstuck and could not unload concrete

on site. There was a bad traffic outside the site. The trucks went back to destroy the concrete.

Also, there was an economic instability, fast and high inflation. Therefore, the client asked the

designer to rush to re$-$design after the initial design failed$\backslash$table$[[$No$,$Risk type,Risk definition,$\backslash$table$[[$Specify the risk and its$],[$category $($Residual$/],[$secondary$/$ inherent$)$ and$],[$occurred in the project$],[$described$]],\backslash$table$[[$Mitigation$],[$action$/$s$]]],[1,,,,],[2,,,,],[3,,,,],[4,,,,],[5,,,,],[6,,,,],[7,,,,],[8,,,,],[9,,,,],[10,,,,],[11,,,,]]$
