How much does a structural engineer cost per hour UK?
As a baseline, structural engineers tend to charge around £50 to £90 per hour for their services. This will likely be at the higher end in London, and if the engineer works for a large firm rather than independently.
Do you need an architect to remove a load-bearing wall?
Taking down a load bearing wall will mean you need to employ an architect or structural engineer to work out calculations for the replacement support that will be used in place of the wall being removed.
Can a steel span 6m?
Structure steel is a versatile building material, though it can be used in great variety of ways. The most economic span range for conventional steel floor and roof framing is from 20 to 32 feet (6 to 10m).
How much does RSJ installation cost?
The average price of RSJ installation of £1600-£2500 is not an inconsiderable amount but when weighed against the potential for structural failure or collapse then its merits are obvious.
Can I purchase an RSJ as supply only?
You can purchase an RSJ as supply only, however, it is not recommended that you take on the job of installing the RSJ by yourself. The calculations involved with installing an RSJ are complex and only a professional can provide the appropriate calculations on how much weight can be distributed across your RSJ.
How are RSJ panels made?
To make an RSJ the steel is heated to around 1,700˚F and roll pressed by both horizontal and vertical rollers under enormous weight to form the required shape. It is then cooled and cut to length.
What size RSJ do I need for my project?
They are generally suitable for more lightweight use due to the small range of sizes commonly produced and their load bearing capacity is only around 4-6kg per metre. It is therefore of limited use in a renovation or home improvement project. The size of RSJ needed will be dependent on the calculations provided by your structural engineer.
