Pile foundations transfer structural loads through weaker surface soils to deeper soil or rock layers capable of supporting them. When a piled foundation does not perform as expected, the consequences can include excessive settlement, structural cracking, pile damage, construction delays and disputes between project parties. However, a problem with a piled foundation does not automatically mean that the piles themselves have failed. The underlying cause may relate to the orig

Planning a house extension often starts with questions about the design, planning permission and construction. But one of the most important decisions is below ground: what type of foundation will support the extension? Not every house extension needs piling. Many can be built using traditional shallow foundations, such as strip or trench fill foundations. However, where the ground near the proposed extension is weak, variable, unstable or affected by other site constraints,

The foundation is one of the most important parts of a house extension. It transfers the weight of the new structure into the ground and helps the extension remain stable over its design life. However, there isn't one foundation type that is suitable for every extension. The right solution depends on factors including the proposed loads, ground conditions, existing foundations, nearby trees, drainage, site constraints and the design of the extension. Choosing a foundation bas

Planning a house extension involves more than deciding where the new walls, windows and doors will go. The extension needs to work safely with the existing building, and the structural elements need to be designed to support the loads involved. This raises a common question for homeowners: do I need a structural engineer for a house extension? In many cases, structural engineering input is required where the project affects load-bearing elements, foundations, roofs or the way

The cost of a house extension in London is rarely decided by floor area alone. Two extensions of the same size can have very different prices if one needs deep foundations, large steel beams, drainage changes or complex access through a terraced house. As a broad guide for 2026, many London house extensions fall somewhere between £2,500 and £4,500+ per m² for the main build, depending on specification and complexity. High-end projects, difficult sites and major structural alt

Construction disputes often involve technical questions that cannot be answered through legal arguments alone. A disagreement may involve defective foundations, piling problems, structural movement, ground conditions, design responsibility or whether construction work was carried out in accordance with the design. This is where an expert witness may be required. An expert witness provides an independent professional opinion on technical matters within their area of expertise.

Thinking about removing a wall to create a larger kitchen, open-plan living space or better layout? Before any wall is removed, you need to know whether it is carrying part of the building. A load-bearing wall supports weight from the structure above and transfers that load down through the building. Removing or altering one without understanding how the loads are supported can lead to cracking, movement or more serious structural problems. The good news is that there are sev

Planning an extension, removing a wall, buying an older property, or noticing cracks can leave you with one important question: Do you need a structural engineer? A structural engineer assesses how a building carries loads and whether its structural elements are strong and stable enough for their intended purpose. Their work can involve beams, columns, foundations, walls, floors, roofs, and structural alterations. Not every building project requires engineering input. Knowing

Building problems often begin where people cannot see them. Weak soil, poor drainage, unstable ground, and hidden site risks can lead to cracks, delays, and expensive repairs. That is why many homeowners, builders, and developers search for a geotechnical engineer near me before starting a project. If you want reliable advice and practical engineering support, JPMANN could be the right choice. Their experience, technical knowledge, and client-focused approach help projects st

Introduction If you’re planning a construction project in the UK—whether it’s a house extension, new build, or commercial development—you may be wondering: Do I really need a geotechnical engineer? The short answer: in most cases, yes especially if you want to avoid costly structural issues later. This guide explains exactly when you need a geotechnical engineer, what they do, and how they can save you thousands in foundation costs. What Does a Geotechnical Engineer Do? A geo

Seismic activity in the UK has historically been considered low risk. However, evolving risk models, infrastructure ageing, and updated earthquake engineering standards are changing how engineers approach structural design. With the anticipated Eurocode 8 updates in 2026, there is a growing need for engineers to rethink traditional practices and integrate more robust seismic design UK strategies. The focus is shifting towards structural resilience , advanced analysis metho

The Building Safety Act 2026 represents one of the most significant regulatory changes in the UK construction industry in decades. Introduced to improve accountability, transparency, and safety across the built environment, the legislation places increased responsibility on professionals involved in the design and construction process. For structural engineers, the new framework introduces stricter compliance requirements, clearer documentation standards, and a more rigorous
