What are Structural Design & Calculations?

Structural design and calculations involve a comprehensive engineering process carried out by a qualified structural engineer to ensure a proposed structure is safe and stable. This process is critical for establishing the required framework that will safely resist all forces acting on the building. It encompasses the detailed analysis of loads, the selection of appropriate materials, and the accurate sizing of elements (beams, columns, foundations) to prevent collapse, excessive movement, or failure. The resulting documentation is mandatory for obtaining Building Control approval for almost all new construction, extensions, and structural alterations.

What Does the Structural Design Service Include?

Load Calculations: Precise analysis to ensure the structure can safely hold its own weight (dead loads) as well as the weight of any occupants, furniture, equipment, and environmental forces (live loads).

Structural Analysis: Detailed verification that the proposed design is structurally stable and has sufficient resistance to bending, shear, and axial forces for the intended use.

Material Calculations: Determining the optimal length, size, grade, and quantity of materials required (steel, timber, concrete) to guarantee integrity and avoid unnecessary over-engineering.

Foundation Calculations: Calculating the required type and size of foundations necessary to safely transfer the entire building load to the supporting ground.

Compliance Certification: All designs and reports are prepared to a rigorous standard, aligned with British Standards, Eurocodes, and local authority requirements for immediate submission.

Why Structural Design Matters

Accurate structural design is the single most important factor for securing the safety and longevity of your building. It is the mandatory process required to obtain Building Control approval for any alteration or new build. Furthermore, our approach incorporates sustainability by optimising material use, which directly reduces both construction costs and the project’s embodied carbon. By investing in certified, precise structural calculations, you ensure that your design is not just compliant, but also efficient, reliable, and sustainable from the foundation upwards.

How Our Accredited Assessors Support You

Our qualified structural engineers are chartered professionals with deep expertise in compliance and sustainable design. We use advanced analysis tools to model how your building will perform, identifying the most efficient, low-carbon solutions. We integrate our calculations seamlessly with our clients’ architectural drawings, ensuring the design is buildable and coordinated. We provide continuous support throughout the regulatory process, supplying any additional calculations or clarifications required by Building Control to secure smooth, timely approvals and keep your project timeline secure.

Frequently Asked Questions

Open All

A structural engineer ensures your building is safe, stable, and compliant by designing the framework that supports and safely transfers all loads to the ground.

Yes, most extensions, loft conversions, internal wall removals, and new builds in the UK require certified structural calculations for Building Control approval.

Simple projects can be designed within a few days, while larger or more complex builds may take several weeks depending on the scope and level of analysis required.

Yes—structural designs and calculations are prepared to fully comply with current Building Regulations and relevant British Standards/Eurocodes.

Absolutely—the engineer will provide any additional calculations, drawings, or clarifications needed to secure approval, ensuring a smooth path to compliance.

Dead loads are the permanent weight of the structure (walls, roof). Live loads are variable weights, such as occupants, furniture, snow, and wind pressure.

It is the detailed process of ensuring the proposed design has sufficient strength and stability to handle all calculated loads without failure or excessive movement.

Yes, Foundation Calculations are a core part of the service, determining the required size and type of foundation needed to support the structure safely.

We require architectural drawings (plans and elevations), a clear scope of works, and any site investigation reports if available.

By precisely calculating the required size and quantity of materials, we help eliminate costly over-engineering, directly reducing the material consumption and embodied carbon of the build.
