WOOD TECHNICALITIES American white oak came on the scene through discussions between Arup and the American Hardwood Export Council, which also provided technical advice and helped source the Ɵ mber. “The imagina Ɵ on of the architects, the inspira Ɵ on of the engineers and the skill and tenacity of the fabricators have produced a landmark structure, which is a pivotal moment in the evolu Ɵ on of Ɵ mber construc Ɵ on. This is also an exci Ɵ ng moment for us (AHEC), turning our vision of what might be possible structurally with our hardwoods, into a reality,” said David Venables, AHEC European Director. The American white oak beams were manufactured by German timber specialist Hess Timber. Each beam measures 900mm x 350mm at the deepest point. The longest glulam beam weighs approximately four tonnes and measures 23.4 metres in length. The AHEC Grown in Seconds sustainability calculator showed that the 100m 3 of American white oak lumber used to fabricate the beams would take only 160 seconds to be replaced in the American forest. “An advantage of American white oak’s stiffness and uniformity was that we could predict deŇec Ɵ on levels and camber very precisely,” said Markus Golinski, head of Sales, Hess Timber. The beams also extend back using the same roof fabric, but double-skinned with a mid-layer of Aerogel insula Ɵ on. “So we have the same translucency, but, combined with double glazing and renewables, including ground source hea Ɵ ng, it enables the building to be used for hospitality all year round. Then on summer match days the wide windows can be thrown open, crea Ɵ ng one space that engages spectators with the game,” said Johnson. Lord’s new stand marks another milestone in American hardwoods’ di ĸ cult journey to get to this point in structural uses, but this project, Venables said, “should really open architects’ eyes to this alterna Ɵ ve op Ɵ on for their structural materials por ƞ olio at a Ɵ me when they’re looking to build more with wood worldwide.” | WIA
