1- إذا اشترط صاحب العمل أن يقدم المقاول المواد كلها أو بعضها؛ كان المقاول مسؤولًا عن توفر الشروط والمواصفات المتفق عليها إن وجدت، وإلا التزم بأن تكون وافيةً بالغرض المقصود وفقًا للعرف.
2- إذا كان صاحب العمل هو الذي قدم المواد؛ التزم المقاول بأن يبذل في المحافظة عليها عناية الشخص المعتاد وأن يراعي في عمله الأصول الفنية وأن يرد إلى صاحب العمل ما بقي منها.

Article 463 explained in plain English
This article sets out the contractor's obligations concerning materials, building on Article 462, which provided that materials may come from the contractor or from the client.
First case: the contractor supplies the materials. If the client stipulates that the contractor supply all or some of the materials:
- The contractor is responsible for meeting the agreed conditions and specifications, if any.
- If there are no agreed specifications, the contractor must see that the materials are fit for the intended purpose according to custom.
Second case: the client supplies the materials. The contractor has three obligations:
- To give the materials the care of an ordinary person in safeguarding them.
- To observe the technical rules in the work.
- To return to the client what is left of the materials.
The practical message for the client is that setting specifications in the contract protects the client's right, because where there are none, the standard of custom and the intended purpose is used. It is followed by Article 464, which puts the expenses of the machines and tools needed to complete the work on the contractor unless otherwise agreed. The text does not itself state the consequence of breaching these obligations, and to assess a particular position it is advisable to consult a lawyer specializing in civil matters or in contracting and real estate cases.
Practical example
Sarah contracted with a contractor to build her house wall in Riyadh and stipulated that the contractor supply the bricks and cement without setting any particular specifications. Here the contractor must see that the materials are fit for the intended purpose according to custom. Had Sarah bought the materials, the contractor would have had to safeguard them with the care of an ordinary person and return what is left after the work.
