Structural Calculations
The design figures for each structural element, loads, spans and member sizes, prepared to current standards for Building Control.
Building Regulations
Building Regulations Structural Calculations London
Structural calculations are the figures and supporting details that demonstrate your structural work is safe, and they are what Building Control need before they will approve it. EMA Structures prepares calculations for steel beams, wall removals, extensions, loft conversions and more across London.
When You Need Calculations
When Building Control require structural calculations
You need structural calculations whenever building work changes how loads are carried and that work needs Building Regulations approval. Building Control, or an Approved Inspector, must see that the new or altered structure has been designed by a competent engineer before they sign off the work. If you are selling a property where past works were carried out without calculations, a pre-sale structural review can flag what may need to be addressed retrospectively.
- Removing a load-bearing wall
- Installing a steel beam (RSJ)
- Designing padstones and bearings
- Building an extension
- Converting a loft
- Forming new openings
- Altering or adding foundations
- Supporting a Building Control submission
The Calculations Package
What's in a calculations package
A complete, submission-ready set of calculations and the structural details Building Control and your builder need.
Steel Beam Design
Sizing and design of steel beams (RSJs) and goalpost frames for wall removals and new openings.
Padstones & Bearings
Padstone and bearing design so beams transfer load safely into the supporting walls below.
Load-Bearing Wall Removal
Confirmation of whether a wall is load-bearing and the supporting beam design needed to remove it.
Structural Details
Supporting structural details and drawings where required, showing connections and key dimensions for the builder.
Building Control Responses
Responses to any technical queries Building Control or your Approved Inspector raise during approval.
How It Works
How the process works
A clear, four-step route from your drawings to calculations issued for Building Control.
1
Send drawings
Share your architect's plans, photos or a description of the work for review.
2
Review
We review the scope, confirm what calculations are needed and agree a fee and timescale.
3
Calculations & details
We prepare the structural calculations and any supporting details to current standards.
4
Issued for Building Control
You receive a submission-ready package, and we respond to any Building Control queries.
Drawings & Details
Working from your drawings
In most cases we work directly from your architect's drawings, producing calculations and details that align with the proposed design.
Where structural drawings or additional details are required, for example beam layouts, connection details or padstone details, we provide them as part of the package so the work can be built exactly as designed. Send us the existing and proposed plans, sections and elevations and we will confirm what is needed.
- Steel beams
- Padstones
- Load-bearing wall removal
- Extensions
- Loft conversions
- Structural details
FAQs
Building Regulations calculations, questions
What do Building Control need from a structural engineer?
Building Control need structural calculations and supporting details showing that any new or altered structural element has been designed to current standards. This typically includes the calculations, member sizes such as beams and padstones, and the structural details needed to build the work.
Can you work from my architect's drawings?
Yes. In most cases we work directly from your architect's drawings. Send us the existing and proposed plans, sections and elevations and we will produce calculations and details that align with the design.
Do you provide steel beam (RSJ) calculations?
Yes. We size and design steel beams (RSJs), goalpost frames and the supporting padstones for wall removals and new openings, and provide the calculations and details for Building Control.
How quickly can I get calculations?
Straightforward domestic calculations, such as a single beam or wall removal, can often be issued within a few working days of receiving suitable drawings. We will confirm a timescale for larger or more complex projects when we review your information.
