62 Buckingham Gate

62 Buckingham Gate is located on the north side of Victoria Street and will comprise 23,450 sqm of office space over 11 floors and 1,540 sqm of retail on the ground and upper basement floors. The twelve storey building, due for completion in 2013, offers practical and flexible floor plates in this burgeoning creative extension of the West End.

The 16,000 sqm all-glass surface uses Saint-Gobain’s Cool-Lite SKN154 in both laminated andheat-strengthened variants to ensure a consistent appearance between the vision and shadow box zones. For the ground floor glazing the recently launched Cool-Lite Xtreme was chosen for maximum transparency combined with low solar heat gain.

Load-bearing strutting beam;
10,000mm span, 203 x 203mm cross section.

Steel: resistant to corrosion, durability, high compressive strength.
The beam can save 10%-15% material and can be easier to utilize when constructing flamboyant designs.
Lighter than concrete means it is easier to carry without compromising on stability and can be used in earthquake-prone zones.
Steel beams also reduce the overall dust polluting building sites and can be used regardless of the weather conditions.

No joints involved in the H beam – rolled steel beams are manufactured by passing pliable metal through sizeable rollers to flatten and mould it into the intended shape. This shape is also advantageous as it helps to reduce the overall weight of the structure. Galvanised: coated in a protective layer of zinc to prevent rusting.

With a theoretical weight of 17.2-28.3kg/m, the beams should weigh approx. (avg.) 22.75 x 10 = 227.5kg but likely to be less dense at 172kg as the project is at a small scale, where extensive beams are not necessarily required.

Project: Oriana II Oxford Street

Client: Oriana GP (Land Securities/FREP Joint Venture)

Architect: ESA

Cost Consultants: William Dick Partnership

Project Manager: William Dick Partnership

Structural Engineer: Richard Watkins Partnership

Project Oriana was a major retail refurbishment of a number of historical buildings in the heart of London’s West End shopping district. The scheme involved the demolition of the buildings fronting Oxford Street and the structural alteration of the former Vigin Mega Store.

McLaren were engaged to work with Frogmore and Land Securities to bring the differing collection of buildings into a single 140,00 sq ft shell.

Oriana GP required modern, flexible layouts for rent, the works delivered layouts suited to the needs of high end retail tenants.

The work on site involves the partial demolition and strip out of the existing building, formation of a new basement and the construction of a new multi-storey structural steel frame clad in stone and glass.

The new configuration consists of a tenant escalator and lift voids, in addition to vehicle loading bays to the rear and landlord area. Externally the listed façades underwent extensive restoration to reveal the impressive early 20th century stone features.

The site confines meant that all works had to be contained within the building footprint and logistical procedures involved ongoing consultation with two local authorities, in addition to careful coordination with TFL and the Crossrail works ongoing to Oxford Street & Tottenham Court Road.

Building Component: The main components on the buildings in Oxford Street were stones and brick construction. Specifically the use of the red brick, and the “brickwork has been the five courses to the foot instead of the orthodox four courses”. Along all of Oxford street (before the demolishing process) at the shop level the marteial at the front was always red bricks.

Stone components were what then began to replace the red bricks.

This building is constructed using a skeleton framing system. Where vertical H columns and horizontal I beams constructed a rectangular grid. This supports the floors.

Building component

The building component I have chosen is a Steel column, which is 2.7 m in height and .4M in width. The column is constructed off site then erected in place.

 

Materials.

These I columns are commonly made out of structural steel. Structural steel is a material formed with a specific shape or cross section. Within each country there is a different regulation for structural steel, The normal yield strength in Europe grades available are 195, 235, 275, 355, 420, and 460

These I columns are constructed off site using a process called “Hot Rolling”. This is done by recrystallizing the structural steel. After the grains deform during this process they recrystallize.

These columns need to be protected from Fire.  These columns, which are currently exposed, will be covered using masonry, plasterboard or sprayed with a coating. If the columns were not been protected in some way a fire could possible weaken the material nature and cause a collapse.But it would take a substantial amount of heat to cause this , around 700C.

The difference between columns and the beams, which are attached to it, is that the goal of the column is to take the compression load from the structure.
