Final answer:
The instruments of service are protected by copyright law, and it is generally not permissible for contractors or suppliers to reproduce them without permission.
Step-by-step explanation:
According to copyright law, the instruments of service, such as architectural plans or engineering designs, are protected by the rights of the original creator. Therefore, it is generally not permissible for a contractor, subcontractor, sub-subcontractor, or material or equipment supplier to reproduce these instruments without the permission of the creator.
For example, if an architect creates architectural plans for a building, they hold the copyright to those plans and have the exclusive right to reproduce them. Anyone else, including contractors and suppliers, would need to obtain the architect's permission to reproduce the plans.
This principle applies to various industries, not just construction. It is important to respect and protect intellectual property rights to ensure fair compensation for creators and promote innovation.
