A Beginner’s Guide to SuDS for Architects and Planners

Drainage might not be the first thing that comes to mind when sketching out a new development, but it is increasingly one of the most critical. With local authorities tightening planning requirements and climate change driving heavier rainfall events, sustainable drainage systems (SuDS) have moved from being an optional add-on to a central part of design. For our fellow architects and planners, understanding the basics of SuDS is becoming essential.

What is a Bridge Scour Assessment?

When a bridge is subjected to scouring, erosion caused by fast-flowing water, its foundations can become undermined. It is vital that regular bridge scour assessments are carried out to protect not only the integrity of the bridge infrastructure but also the safety of those who use it.

Introducing our new Civils & Drainage Technical Director, Scott Webster

Scott joined AWA in early 2025, bringing over 30 years of civil engineering experience and a proven record in leadership and project delivery. For the past seven years, he led a team of 11 engineers at a leading civil engineering firm, collaborating across multiple departments to successfully deliver major projects.

Getting the right marine engineering advice for your sheet pile walls

Sheet pile walls are retaining structures designed to hold back earth, water, or other fill materials. Constructed from rolled steel, they are quick to install, durable, and can be made watertight, making them the preferred choice for port and harbour walls.

Five benefits of Structural Insulated Panels (SIPs)

Considering alternative materials for your next project? Structural Insulated Panels (SIPs) are becoming an increasingly popular choice for walls and roofs.

Although often seen as a modern innovation, SIPs have actually been around since the 1930s. Over the decades, they’ve been refined and improved to deliver exceptional performance, combining strength, efficiency, and design flexibility. Today, they are especially well-suited to one- and two-storey dwellings and new-build homes.

In this article, we’ll explore the key benefits of Structural Insulated Panels (SIPs) and explain why they could be the ideal solution for your next build.

Bridge Design and Assessment

At AWA Structural Engineers, we specialise in bridge design and assessment, where the role of the structural engineer is paramount. Unlike building projects, bridges are rarely designed with the involvement of architects, meaning the responsibility lies with Civil or Structural Engineers to lead the entire process. This is where our extensive experience comes into play – our proven track record ensures that your project is not only structurally sound but also navigates the complex approval process smoothly and efficiently.

Steel Portal Frames: Design & Construction

Steel portal frames are integral to modern structural design, offering an efficient and versatile solution for constructing large, unobstructed spaces. These frames are particularly valuable in projects like warehouses, industrial facilities, and large retail spaces, where maximising internal space is crucial. Steel portal frames are formed by rigid connections between vertical columns and horizontal rafters, providing stability in the lateral. Vertical bracing provides stability in the longitudinal direction. This arrangement makes steel portal frames highly effective for buildings that require expansive, clear-span interiors.

Foundations for Construction: Pads, Pads with Vibro Stone Columns, and Piles

The importance of getting the right foundation solutions for your construction project should not be underestimated. It underpins the whole project’s success, so it needs to be right. Our dedicated team of engineers is committed to guiding you through every aspect of ground foundations. Our approach guarantees precision and reliability and provides peace of mind.

What is Green Oak Timber?

Green oak timber refers to unseasoned oak that is freshly cut, hence the term ‘green’. It is typically cut within 3 to 18 months after the tree is felled, and retains a high moisture content. Green oak frames are commonly used as the primary structure of a building, rather than steel or masonry, formed with beams, posts, braces, and trusses. The components are joined with traditional carpentry techniques, such as pegged mortise-and-tenon or dovetail joints. Whilst green oak can be expensive it is cheaper than seasoned oak, as this type of wood is air dried or kiln dried therefore has additional costs involved, whereas green oak will dry over time in its final location.
