Things to check in County Down

Diversity

Not every room peaks at once; good design accounts for diversity so central plant is not oversized.

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.

Future use

Allow for growth in occupancy or IT load.

Leased premises

If your County Down premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
