What Are Structural Calculations?

Structural calculations are the analysis used to prove structural safety. They show that a building meets minimum standards and can safely support loads. Structural calculations include checks for beams, foundations, floors, and roofs. They are required for structural works and for construction and alterations that affect stability.

Calculations may be required for openings, extensions, and structural design changes. Calculations are often needed where structural components are altered. They ensure compliance with building regulations and help avoid costly mistakes during the construction process.

Building Project

Every building project requires proper planning and documentation before work begins. Whether you are removing a load-bearing wall, building an extension, converting a loft, or underpinning a basement, we produce the information needed to proceed legally and safely. For projects involving load-bearing wall removal, we provide full structural calculations and drawings. Where excavation is involved, we also carry out basement impact assessments to ensure safety and compliance.

Building Work

Any building work that affects structural components must comply with building regulations. This includes foundations, beams, floors, roofs, and walls. Structural calculations are essential because they show the building is safe and stable. They confirm that the structure can support the weight of loads and stresses placed on it. Our calculations ensure your building is structurally sound, safe and compliant, and able to meet minimum standards.

I appointed AC Design Solutions for a challenging new build project - demolishing an existing house and replacing it with 7 new flats in Isleworth. The team provided a comprehensive service including architectural design, structural engineering calculations, building regulations drawings, and preparation of all the technical reports required for planning (drainage, energy, daylight/sunlight, arboricultural, etc.). The project was taken to Hounslow Planning Committee and we achieved unanimous approval on the first attempt. AC Design Solutions were very responsive throughout, handled all the pre-application consultations, and prepared a strong case that addressed all the planning concerns. Their knowledge of local planning policies and building regulations was excellent, and they coordinated all the specialist consultants we needed. The building regulations drawings were detailed and compliant, ready for submission. I would highly recommend AC Design Solutions for residential development projects in West London. Really pleased to have these guys on my team - they are absolutely on the ball, and I look forward to doing many more projects with them in expansion of my portfolio.

Had a great experience with AC Design, the customer service was great and they responded to our questions promptly. Turnaround for designs were quick too. I especially appreciated having a call with the engineer as it helped us understand why the designs were constructed in a certain way. Highly recommend this company if you require structural drawings done

Structural Engineer

Our qualified structural engineer team provides analysis for building projects across London. Each structural engineer holds relevant qualifications ensuring calculations meet current design codes. A structural engineer assesses loads affecting your building while designing structural components that maintain safety.

Working with an experienced structural engineer ensures your building project achieves building control approval efficiently. Our structural engineer team understands local and national policies affecting construction.

Structural Calculations for Building Control

Structural calculations for building control must show safety rule compliance. These structural calculations for building control prove structural components work safely. They support expected loads ensuring your building remains safe and stable.

Making structural calculations for building control needs detailed checks. Our structural calculations for building control include foundation design, beam sizing and load checks. Building control officers use structural calculations for building control to assess safety.

Structural Engineer

A structural engineer ensures that a building is safe during design and construction. This includes checking loads and stresses and reviewing structural components. The aim is to confirm the building remains safe and stable at all times. Our engineers follow British Standards, Eurocodes, and design codes. We also work in line with local and national policies and the regulations set by building control.

Need Building Regulations Approval

If you need building regulations approval, structural calculations are required. These are submitted as part of the submission to building control. They demonstrate compliance with building regulations and confirm the building meets the regulations set by the authority. Proper documentation helps speed up approval and avoid delays.

Structural Drawings

Structural drawings convert calculations into clear instructions for construction. They show beam positions, connections, and support details. They also include detailed plans, sections, and roof plan information.

We produce drawings in CAD and coordinate them with architectural drawings. This reduces conflicts during the construction process. It also helps ensure safety and compliance throughout the design and construction stages.

STRUCTURAL DESIGN SERVICES

Structural Design

Structural design turns calculations into a buildable solution. It considers structural safety, cost, and buildability. It also ensures compliance with building regulations. Good structural design ensures the building remains safe and stable during and after construction.

Structural Surveys and Defect Investigations

Some projects require a survey before calculations are prepared. Our structural survey London service identifies defects and structural issues early. This helps ensure safety and compliance and reduces the risk of costly mistakes.

Building Regulations Completion Certificate

Once work is completed and approved, building control issues a building regulations completion certificate. This confirms the building meets required standards. Accurate structural calculations make it easier to get building regulations approval and complete your project successfully.
