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.
Conservation areas
Historic streets and listed buildings in and around Portishead are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
