This is an example in a small series for illustrating the concepts in What is a good or service that is distinct?
A building contractor (the vendor) enters into a contract to build a new office block for a customer. The vendor is responsible for the entire project, including procuring the construction materials, project management and associated services.
The project involves site clearance, foundations, construction, piping and wiring, equipment installation and finishing. Although the goods or services to be supplied are capable of being distinct (because the customer could, for example, benefit from them on their own by using, consuming or selling the goods or services, and could purchase them from other suppliers), they are not distinct in the context of the vendor’s contract with its customer.
This is because the vendor provides a significant service of integrating all of the inputs into the combined output (the new office block) which it has contracted to deliver to its customer.
