– Remove everything from the room being renovated, hang dustsheets and cover the floor surface if it is in good condition and needs to be protected. Make sure the below structure have sufficient capacity to support the new loads from the columns. – The load from these columns will have to be tracked through floors below. – Steel columns (square and round) – for heavy loads – Use 4×4, 6×6 studs – for intermediate loads – Longer span beams require deeper beam sizes. The beam will have to be supported by either a column or solid wall at both ends. If an exposed timber beam is preferred then a calculation is generally required to demonstrate how much inherent fire resistance it has – dependent on its size and species of timber.Ī concrete beam has adequate fire resistance properties.Ĭonsiderations: Generally, installing the beam is a two person job. This resistance can be achieved using two or more layers of plaster-boards. In many cases a full-service lumberyard will size the beam (all support beams are rated according to their load) and sell it to you.ĭepending on the span and loading conditions, the beam might consist of multiple plies of dimensional lumber, heavy timber beams, multiple plies of engineered lumber, solid engineered lumber or steel.įire Safety: If the beam is steel then it should normally be protected against fire so that it will have 30 minutes resistance to fire (if measured in a standard test).

The structural engineer will check the size, issue a permit and check your work when you’re finished framing (before you start any drywall or finish work). Before removing a load-bearing wall, a structural engineer or surveyor can be employed to determine if the wall is load bearing and then design a beam to cater for these loads. Structural Support: However, if you wish to remove an internal wall, or form an opening in an internal wall, building regulations will normally apply.

Mediterranean Style Homes | How To Build A House () If a wall is running parallel to them then it probably isn’t load-bearing, while if it is running perpendicular to the joists it might be or should be treated as if it is. What is a load-bearing wall? Load-bearing wall provides separation between rooms and is also required to transfer loads from other parts of the structure, roof and floors etc., down to the foundationsĪ simple way to determine whether a wall is load-bearing is to look in the attic for the direction of the joists.

But what if you want to remove a load-bearing wall? That works fine if you’re removing a partition wall. Maybe you need to open up cramped rooms, to create an open kitchen dining area, or to make a larger living room and so on. There are many reasons to replace a wall with a load bearing beam.
