Foundations & Levels
Strip, trench-fill, slabs, and retaining walls with setting-out levels and reinforcement schedules. Designed for local soil conditions and access constraints.
Building Control-ready structural calculations delivered within 24–72 hours.
RSJ beams, wall removals, lofts, and extensions. Chartered IStructE.


SECalcs provides fixed-fee structural calculations for homeowners across Birmingham, Solihull, Harborne, and Edgbaston. We deliver Building Control ready designs within 24 to 72 hours for most domestic projects, helping you move forward without delay.
Every design is completed or reviewed by a Chartered Structural Engineer, giving you safe, efficient, and fully compliant results. We specialise in:
Our process is simple. You send your plans, we confirm the scope and fixed fee, then deliver everything your builder needs. No jargon, no surprises, just clear professional communication.
You receive a complete calculation pack that includes clear structural drawings, beam specifications, and connection details. Our expert team certifies every design, making it ready for Building Control submission.
We handle RSJ sizing, load calculations, and foundation checks so your builder can start work with confidence. For a quote, just send your address, photos of the wall or area, and any existing floor plans. For lofts or extensions, roof details and architect drawings are also helpful. The more information you provide, the faster we can confirm your fixed fee and delivery time.
Most wall removals and RSJ designs are completed within 24 to 72 hours. Larger projects, such as loft conversions or multi-storey extensions, usually take five to seven working days.

We provide pre-purchase structural reports and defect surveys across Birmingham, Solihull, Edgbaston, and Harborne. Our Chartered Engineers assess cracking, settlement, movement, and subsidence in Victorian terraces, 1930s semis, and modern homes. We also investigate local issues such as sulphate attack, lintel failure, and foundation problems common in older Birmingham properties.
Each report includes clear findings, photos, and sketches with practical repair advice. You'll know whether a defect is cosmetic, manageable, or serious. We explain the likely cause in plain language and outline what needs to be done to put it right. Our team prepares or reviews every report to ensure accuracy and reliability, ready to share with your solicitor, insurer, or builder.

A structural report focuses on the building's stability and load-bearing elements. It’s different from a general building survey, which covers finishes and services.
Our report examines foundations, beams, and walls, explains visible defects, and includes sketches with repair recommendations. It helps you make clear, confident decisions when buying, selling, or planning remedial work.
We regularly inspect Victorian and post-war homes affected by cracking, movement, and sulphate-related foundation problems. Our engineers understand local soil conditions and construction styles common to Birmingham.
We assess whether cracks or distortion are long-standing or active and give clear next steps for repair or monitoring, based on local experience and Building Control standards.
Your report includes photos, sketches, and plain-English explanations of every issue. We clarify if repairs are urgent, moderate, or low priority and provide realistic advice on costs and timing.
Each report is checked by a Chartered Engineer and formatted for easy sharing with your solicitor, lender, or builder, so everyone has a clear view of the property’s condition.
We use Revit, AutoCAD, and CIVILS 3D to create precise structural designs and clear 3D models for complex projects. This BIM-based approach helps homeowners, architects, and builders visualise layouts before work begins. It reduces errors, speeds up approvals, and keeps communication simple across everyone involved.
Our engineers design groundworks, drainage layouts, and highway connections for extensions and new builds. We prepare foul and surface water schemes, adoptable road layouts, and Section 38 or 104 submissions where required. All designs follow Building Control and local authority standards.
We also provide Party Wall advice and Temporary Works designs for challenging or confined sites. If your project involves shared walls, close boundaries, or propping during construction, we guide you through each stage and supply compliant designs. Every service is managed by Chartered Engineers with experience across Birmingham and the West Midlands.
3D models built in Revit with levels, grids, and load paths. We coordinate with architectural and M&E drawings to avoid clashes before site.
Clash checks done pre-constructionStrip, trench-fill, slabs, and retaining walls with setting-out levels and reinforcement schedules. Designed for local soil conditions and access constraints.
Beam sizes, connections, and foundations designed to Eurocodes. Peer review by a Chartered Engineer for safety, economy, and buildability.
Chartered review sign-offDrainage layouts, SuDS features, manhole schedules, and adoption drawings for Section 38 or 104 submissions. Coordination with utilities and highways.
PDF drawings and calculation packs ready for Building Control. Revisions tracked and re-issued quickly to keep your programme moving.
BC-ready packs in 24–72hAdvice on shared walls, boundary works, and propping schemes. Needle beams, acrow frames, and sequencing notes for safe construction on tight sites.
Every calculation pack and BIM model is checked by a Chartered Structural Engineer (MIStructE) before issue. Our in-house QA process ensures accuracy, code compliance, and clear communication across all drawings and reports.
We work with your architect and builder to align beam positions, floor layouts, and service routes. This avoids site clashes and keeps your build running smoothly.
We prepare clear, compliant drawings with all structural notes and specifications ready for Building Control submission or your architect’s package.
We stay responsive from start to finish, updating drawings quickly if conditions change on site so your project stays coordinated and buildable.
Independent proof points your clients can trust. Clear, simple, and Building Control ready.
This experience gives us deep insight into local property types, Building Control requirements, and construction practices. You benefit from our proven track record and efficient delivery.
We design efficient, buildable structures that cut material and labour costs. Our engineers specify the right steel sizes, padstones, and fixings without over-engineering. Precise calculations minimise waste and avoid over-specification, saving up to 15% on materials compared with conservative, non-chartered designs. Fixed-fee pricing means no surprises.
