Building Regulations look at the finished project, not just the product. The foundation, building loads, what is known about the ground, drawings and any approval requirements need to line up.
The design shows what loads the ground screw foundation needs to carry.
The screw sizes, positions and fixings should match where the building needs support.
Ground conditions and site information can affect the foundation design and any testing needed.
Building Control may ask for drawings, calculations, product information or installation records.
The drawings and records should show how the building, foundation and site work together.
Drawings or load information showing what the ground screws are supporting.
Where each ground screw sits and what size is being used.
Relevant data for the ground screws, heads, brackets or beams being used.
Any site report or installation information needed for the design.
Checks or records from the installation where the job requires them.
How the building above connects to the finished ground screw foundation.
That is too broad. Building Control deals with the project as a whole. Using a ground screw does not remove the need for the right foundation design and supporting information.
Use the drawings, calculations and product information needed to explain the screw layout, building loads, ground conditions and fixings.
Straight answers on Building Regulations, Building Control, calculations, extensions and the paperwork that may be needed.
Yes, ground screw foundations can be used on projects that need to meet UK Building Regulations. The foundation still needs to be designed for the building and supported by the drawings, calculations or other information required for that job.
It depends on the building and the work being carried out. If Building Control approval is required, the ground screw foundation needs enough drawings, calculations and product information to support the application.
This varies by job, but Building Control may ask for structural drawings or loads, the ground screw layout, product information, details of the ground or installation, connection details and calculations from the designer or engineer.
Yes, on the right project. The extension loads, ground conditions, foundation layout, connection to the building and any Building Control requirements all need to be dealt with for that specific extension.
See extension applicationsIf the ground screws are supporting a building, the foundation should be based on the building loads and layout. The amount of calculation or testing depends on the job and what Building Control or the designer requires.
