W/s Imran,
It is very hard to say if your FYP would help you in securing a job but one thing that is for sure, is that you will get skills like assessing an existing structure, doing base isolation and information about seismic codes and the response of a building to a seismic event - such skills would help you wherever you go. I am not aware of use of base isolators in Pakistan, there might be sensitive military installations where these are being used but I don't know if the market is really big for that and there is immediate need for people having that experience. But like I said above, you will get a skillset that any structural firm in Pakistan would value provided you do your project correct and develop understanding of what you are doing.
Thanks.
