What temporary works & propping involve in West Sussex

Temporary works and propping are the short-term supports that carry floors, walls and roof loads while a structural wall is taken out or a beam is put in. Adjustable steel props, timber spreaders and steel needles pass the weight safely down to the ground until the permanent steel is installed, packed tight and able to take the load itself.

Across West Sussex, temporary works & propping usually come up when people want more light, a better layout or a way through to a new extension. That includes Littlehampton, East Grinstead and Worthing, plus smaller towns and villages nearby. Whatever the reason, the beam is sized from calculations and the work is inspected before anything is covered.

Key points for your project

  • Props and needles cannot go where pipes, cables or flues run. Their positions are checked against services before any holes are cut, and anything in the way is isolated or rerouted first by the appropriate trade.
  • Typical mistakes include props standing on unsupported floorboards, missing spreaders so one joist takes all the load, and props wound up too hard so the ceiling lifts and cracks. Careful setting out and gradual tightening avoid all three.
  • Props take up floor space for the length of the job, usually in the rooms on both sides of the wall. Furniture needs moving back, and nobody else in the house should knock, adjust or hang anything from the props.
  • On larger jobs, a temporary works register or permit records when the props were installed, inspected, loaded and removed. It creates a clear trail showing each stage was checked before the next one began.
  • Propping costs depend on how many props and needles the load calls for, how long they stay in, whether a separate temporary works design is required, and whether props must continue through a floor to reach solid ground.

Four stages, one team

  1. Free visit

    A short visit to West Sussex to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Approvals in West Sussex

For West Sussex, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.

If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Building rules in England

Local questions answered

Which towns in West Sussex do you cover?

We cover towns including Crawley, Worthing, Bognor Regis and Littlehampton, plus the villages and smaller towns around them.

Can you work on older or listed homes in West Sussex?

Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.

Do I need a temporary works design for my job?

Not always. For a simple single opening, the propping shown in the engineer's calculations is often enough. Bigger or more complex jobs, such as removing several walls, supporting chimney stacks or replacing a shopfront beam, may need a separate temporary works design from an engineer, following the BS 5975 approach.

Can I hire props and support a wall myself?

Props can be hired, but propping a structure is skilled work with serious consequences if it goes wrong. The arrangement should come from an engineer's design, and the loads, floor strength and sequence all need checking. Structural propping should be left to a competent team working to that design.

What if props need to go on my neighbour's side of the wall?

Then their agreement is needed first. Where needles pass through a party wall, props may have to stand on the neighbour's side, and in England and Wales that work is normally covered by party wall notices served before work starts. We arrange notices through a party wall surveyor where they are required.

Can I stay in my house while it is propped?

Usually, yes. The props take up space in the rooms either side of the work, so those rooms will be out of use, but the rest of the house can be lived in as normal. The props must never be moved, knocked or adjusted by anyone other than the installation team.

How soon can temporary works & propping start in West Sussex?

Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
