Building: 5 Broadgate, City of London

Architect: Make architects

Engineer: Buro Happold

Contractor: Mace

Element:Perforated metal beams, roughly 4m long and 40cm deep, joint with other beams and metal slabs.

Material: Steel, prefabricated in factory and transported to the construction site. Cross section is shaped as an I and optimised with circle cuts on the thinnest part to take some weight away.  This type of optimised beam is called cellular beam: it can be either fabricated in two parts, which are welded together, or a single part from which the circles are cut off.

explanation of building component: panel slab framework – beam. 150x10x30. 5kg.

material study: aluminium;  fabrication : The company Peri manufactures most of it’s products in it’s production plant in Weissenhorn.

Hollow beam, strong material, Light, Expensive. Good for it’s use as it is a re-usable component (only supporting the casting of the concert floor), and needs to be dismantled and reassembled thus needs to be light and strong. It has a shape made to interlock with other components of the slab panel easily, with abilities of self drainage.

Project: 11 Soho Street – Mixed-use scheme of 70,000 sq ft.

(The retail part of it will be a huge Zara shop, of course).

Architect: Allford Hall Monaghan Morris

Civil & Structural Engineer: The Walsh Group

Mechanical Engineer: MTT

Contractor: GVA Second London Wall

Building Component: Steel formwork for concrete casting. The steel beams are to support wood components, which are placed on top. Both the steel and the wood will be removed once the concrete is set.

The steel formwork is pre-fabricated off-site and is brought in pieces to be assembled quickly. The steel is placed in a grid in which the beams in one direction are thicker than the other. The thicker beams are in the width of about 250mm, and in the height of about 400mm. It looks like each thick beam is actually made of four surfaces creating a cross-section of a hollow rectangle. They are perforated with circles/oval shapes, to reduce weight or perhaps to allow interaction with other building elements. The thinner beams, which are perpendicular, cross through about two thirds of the thicker beams, so their height should be about 250-300mm. Their width – 30mm.
