Describe the premises.
Start with the site location, approximate area and use of the building. Explain which spaces are included and which should remain out of scope.
Identify operational constraints.
Share access hours, occupancy patterns and areas that cannot be interrupted. Mention any site induction or access permission requirements.
Flag special requirements.
Describe surface materials, sensitive equipment and known hazards. Specialist work needs a specific assessment; do not assume a general cleaning enquiry covers it.
Agree what completion means.
Before work begins, confirm the scope, responsibilities, schedule and how the finished work will be reviewed. A clear written agreement helps both parties understand what is included.
