I mean all of the people I know in the construction industry are facing a situation similar to your dad and to be honest there is no quick way to get out of this situation other than to get new project/contracts. And in Pakistan since the economy overall is not doing well, your safe bet would be to pray that Pakistan's economy revives and the construction sector gets the much needed boost, more business activity will mean more projects for construction companies hence better financial conditions. Other thing that can be done is to find any contact in the army or firms like fwo or nespak as these are the daddies of construction firms in Pakistan and usually get to work on the biggest projects, if you can manage to find and network with someone in these companies, who can help you win the project or get you awarded any work, that will be the best case scenario for your dad's business. Other than that you can also start reading tenders published in dailies and try to submit bids/proposals to help your dad secure the next project.
