The NEC4 Professional Service Contract (PSC) is intended for use in the appointment of a supplier to provide professional services. It can be used for appointing project managers, supervisors, designers, consultants or other suppliers under NEC contracts and can also be used for appointing suppliers on non-NEC construction projects or for non-construction projects. NEC4 contracts help to streamline processes, reduce the potential for problems and promote best practice in procurement of professional services.
