Things to check in Ruislip
Future use
Allow for growth in occupancy or IT load.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
