Request for Legal Advice

Good day,
I just want to ask some legal advice. My husband put up a new company together with his 3 colleague. An installation company for facade and glass curtain wall. They got a new project a 32floors tower from their previous GM. The GM issued only a PO or purchased order signed by both parties. Currently the project is ongoing and almost 20% completed. The problem now is the GM or the general contractor who issued the PO wants to take over the project in short he want my husbands company to vacate the site and wants to take also the manpower and other resources. My my husbands company initiated the project, resources, inputed capital, manpower and even got a loan in order to materialized and mobilized this project then suddenly they want to take over. My question is what action or approach should we do. Can we demand for a damages. Please advice.
Thank you. Arlyn

does your husband has a contract with the company?

Good morning. My husbands company has a PO or signed purchased order only for the said construction project

Just want to know also does a signed PO or purchased order a valid document or contract?

yes it is. ang problem sometimes the PO does not contain enough details

The signed PO specified Installation of Curtain walls for the whole tower(32floors) with attached detail of items.

The problem now they want to take over the project in short they want my husband company to vacate the site. My question is, what action should we take. Especially its a big loss for them financially, their resources and manpower

a PO is valid only between the parties. so it is considered valid between your husband and the GM, but not against the building owner
