Filing civil case to recover security cheque for unjust enrichment

I have signed a contract with a contractor to carry out AC works where the owner of the company has paid me cash with a payment voucher and he asked to provide a security deposit cheque.

My scope of work was supposed to be finished in 45 days but delayed due to civil works for more than 4 months, in the interim we have continued to work and finished the works and started the equipment.

Our final bill is linked with authority approvals which cannot be accomplished without civil works. I have asked the contractor to pay the VAT and amount for variation which he failed to do so.

After 4 months the contractor called to resume the works where I have rejected as he failed to fulfil the contractual obligations. I've written a letter to the owner that I will take legal action if he misuses the cheque.

The owner deposited my security cheque and filed a case. If I file a civil case against the owner, am I entitled to get losses incurred due to damaging my relation with the bank and other legal expenses?
