Which UK standards have been replaced? On an ISO 19650 produced project, is the contractual framework the same? Are there any new roles or responsibilities that the ISO introduces?

Within the report you are required to discuss the ISO 19650 series and compare them with the PAS 1192 documents. The ISO 19650 standard is an international standard for managing information over the whole life cycle of a built asset using building information modelling . It contains the same requirements as the UK Governments BIM Level 2 and is closely aligned with the UK 1192 standards.
Within these two tasks, the first two international standards of the ISO 19650 series need to be discussed:
BS EN ISO 19650-1: Concepts and principles.
BS EN ISO 19650-2: Delivery phase of the assets.
In exploring those documents, you may want to think about some of the following questions:
Which UK standards have been replaced?
On an ISO 19650 produced project, is the contractual framework the same?
Are there any new roles or responsibilities that the ISO introduces?
What size of project can the ISO be used on?
Should we now ignore BS 1192:2007, PAS 1192-2, and PAS 1192-5?
