The load-bearing wall is a structural component which supports loads coming from the upper parts of the building or house. This wall transfers the loads to the lower components (beams, soles, foundation, etc.). The upper parts represent, among other things, the roof, the floors on the upper floors, the upper load-bearing walls, etc.
To determine whether a wall is load-bearing, the engineer must analyze the loads it bears. To do this, they drill exploratory holes in the finish if the structure is not visible. After taking on-site measurements of the loads and dimensions, and after analyzing the feasibility of removing the wall, the engineer performs calculations and creates plans to replace the wall with a structural system [composed of beams , columns, and footings]. It is crucial to adequately support the structure when removing a wall.
In general, a wall in houses and residential buildings can be replaced with a timber beam (usually made of LVL) and timber or steel columns. These columns must rest on poured concrete footings. Sometimes, a timber beam is insufficient to support the loads, and a steel beam is then used. Indeed, the loads and the span (beam length) are the factors that determine whether the wall should be replaced with a timber or a steel beam.
Our structural engineer has the skills to perform the following tasks:
1- Carry out an inspection of the building and perform a detailed survey of the structure;
2- Analyze the structure and propose an appropriate solution;
3 - Preparation of construction plans;
4- Specify the construction materials to be used (example: LVL beam, steel column etc.)
Finally, to execute the construction plans drawn up by the structural engineer, it is necessary to hire a qualified contractor.
