1.1 Structural loading of buildings

STFC buildings have been designed and built for a large variety of uses, some of which have changed over the years. Before a change of use or an extension of existing use is made, the proposal must be referred to the Estates Group to ascertain whether the building is structurally capable of meeting the changed requirements.

1.2 Attachments and holes

Approval must be obtained from Head of Estates Groups before loads, supports or fixings are attached to columns, walls or ceilings, or holes for fixings, access or services are made in columns, walls, floors or ceilings as such loads and holes may weaken the structure.

1.3 Loads on floors

A filing cabinet or rack may not be heavy on its own but may cause a structural overload if filled with numerous items which also may not be heavy individually. Overloading may also occur if items of insignificant individual weight are concentrated on certain parts of a floor.

Approval must be obtained from Head of Estates Groups before any load other than normal furniture is placed on a suspended floor. A layout of racks or equipment which has been agreed must not be rearranged, modified or increased without obtaining further approval.

General design floor loading figures must not be used by occupants to solve any problem, these figures are affected by a number of factors which may not be known to the occupant.

1.4 Seeking advice​

The Head of Estates Groups are available for discussion on specific structural loading problems and can often assist by suggesting a modified layout or in extreme cases carrying out alterations to strengthen the structure.

1.5 Mechanical lifting

Where additional mechanical lifting facilities are proposed reference must also be made to the SHE Group.
