Green Oak Frame Structural Engineering

Green oak timber is unseasoned ‘green’ oak, freshly cut within 3 to 18 months after the tree is felled, retaining high moisture content. Green oak frames are the primary structural element of a building, instead of steel or any other masonry, held together using pegged mortice, tenon, dovetail and other joints. The oak members can be infilled with other timber or brickwork to make it look as pleasing as possible. The timber can be beams, posts, braces or roof trusses.

What AWA Do

Our services cover all aspects of structural engineering for green oak frame buildings, from complete project solutions to specific engineering advice. Whether you need us to design and provide calculations for individual elements of your project or create a full structural engineering solution for the entire building, we can tailor our services to meet your needs.

Our structural engineering designs provide comprehensive, mathematically calculated design proofs. They outline all engineering aspects of your building including material usage, joints, fixings, and section sizes. These designs are essential for developing the final project plan and are frequently referenced throughout the sourcing and construction phases. Our team of chartered consulting engineers is equipped to assist with any structural issues. We work directly with you, your architect, or your engineers to provide expert guidance and support.

Do you need a Green Oak Frame Structural Engineer for your Project?

At AWA Engineers, we specialise in providing calculations and drawings for the structural design of green oak frames. These comprehensive deliverables are essential for a building regulations application. Many structural engineers lack expertise in working with green oak buildings, as it is a specialised area. Our specialist oak frame engineers have extensive experience in this niche to help you create structures that are not only beautiful but also durable.

We recommend involving our team as early as possible in the design process. Even if you already have an architect our expertise can provide valuable guidance and advice on the specific design considerations and processes relevant to oak frames.

Our Services Include:

  • Custom Design of Green Oak Frames: Tailoring designs to meet specific client and site requirements.
  • Structural Analysis and Engineering: Ensuring that all green oak constructions meet current building codes and performance standards.
  • Project Management: Overseeing all phases of design from initial scheme to construction, ensuring seamless integration and timely completion.

Why Choose AWA Engineers for Your Green Oak Project?

Engaging AWA Engineers ensures that your green oak framing project benefits from:

  • Expert Guidance: Our engineers and designers have extensive experience in both traditional and innovative uses of green oak.
  • Custom Solutions: We provide bespoke designs that perfectly fit the unique needs of your project, from aesthetic detailing to structural requirements.
  • Commitment to Quality and Sustainability: We are dedicated to delivering high-quality constructions that respect environmental concerns and heritage conservation guidelines.
  • Innovative Use of Green Oak: We are proud to push the boundaries of what can be achieved with green oak framing. Our innovative approach means we can provide drawings for some of the more challenging designs.

Any structural timber frame should be evaluated by a competent structural engineer. As oak dries, it becomes harder and stronger. Despite being relatively low in weight, oak is highly dense. During the drying phase, oak may experience creep deflection, splitting, shrinking or distortion. Therefore, the joints should be designed to “tighten up” as the wood dries. Due to these unique characteristics, it is essential for the structure to be designed by specialists. For anyone planning a building project with a green oak frame, from residential homes to commercial structures or restoration of historical buildings, our team is equipped to provide expert engineering solutions.
