Beam Design 


Laytoe’s beam designs and calculations conform to Building Control regulations.



Our structural engineers determine if a wall is load bearing. We then calculate the size and material of the beams required for safe removal. We’ll also assess the correct size of padstones to spread the load on existing walls – where they support other walls, roofs or floor joists.

  • Calculation for splice connection
  • Pad footing design
  • Steel column and baseplate design
  • Residential and commercial beam design
  • Steel (RSJ), timber and concrete beam calculations
  • Cantilever design for use with trusses and slabs



An experienced builder will know what size beams I need, why do I need Laytoe?


Your builder will only know AFTER a structural engineer has calculated the how much load will be taken by the beam. Laytoe will provide calculations and drawings along with installation recommendations which you can then take to your building control office for approval before your builder orders or installs a load-bearing beam.


Can’t I use an online beam calculator?


Online beam calculators do not provide the precision and other relevant factors that Laytoe’s structural engineers are able to assess during a site survey. Lintels, for example, require an experienced engineer to calculate how much load is applied from the wall above and how much weight and force (load) should be transferred to the walls on either side of a new opening.


How does Laytoe calculate and design beams? 

Our structural engineer visits your property and measures the width and depth of the wall where the beam is to be installed. They will then calculate the load-bearing capability required of the new beam. Different loads are applied depending on the design of existing roofs, floors, walls and also from other beams in the building.
