Can you direct me to any documents that relate to temporary fire protection requirements for a building during construction stage i.e., requirements for dry riser / wet riser? This will help me plan jobs correctly in the future.

The issue of temporary fire protection requirements during the construction stage of buildings is addressed in BS9990:2015 Paragraph 7.2. It states the following:
In order that a fire occurring during the construction of a building can be dealt with effectively, especially in high or extensive buildings where large quantities of combustible materials might be stored, mains should be in an operational condition as soon as any floor of the building reaches 11 m above fire service access level. These mains should be extended and commissioned progressively as work on the building proceeds to provide firefighting facilities at all stages of construction. Where wet mains are provided, installation initially can be as a dry main. When construction reaches 50 m, the system should be commissioned as a wet main in accordance with the relevant recommendations of this British Standard.
