The document summarizes the Gherkin building in London, designed by Norman Foster. It is a 180m tall skyscraper constructed from 2001-2004 that uses a distinctive twisting shape and high-tech architecture design. Key features include a diagrid structural system, double-skinned facade for natural ventilation, and sustainability measures like computer-controlled windows and daylight wells. The building won awards for its innovative design and engineering.

THEGHERKIN WHAT IS HIGH – TECH ARCHITECTURE ?  STRUCTURAL EXPRESSIONISM EMERGED BY 1980’s.  CELEBRATES DISPLAY OF BUILDING SERVICES.  EXTENSIVE USE OF GLASS AND STEEL  FLEXIBLE INTERIORS  USE OF COLOURS TO INDICATE DIFFERENT SERVICES  LIGHTWEIGHT MATERIAL  GLASS SKINS  PIONEERS : NORMAN FOSTER, RICHARD ROGGERS, I.M.PIE, etc.
THEGHERKIN BUILDING : 30 ST.MARY AXE,LONDON, U.K STYLE : HIGH TECH ARCHITECTURE , NEO FUTURISM FUNCTION : OFFICE SKYSCRAPERS OWNER : SAFRA GROUP ARCHITECT : NORMAN FOSTER CONSTRUCTION : 2001-2004 HEIGHT : 180M (591ft) FLOORS : 41 AREA : 47,950sq.m ABOUT PROJECT:
THEGHERKIN ABOUT PROJECT:  30 ST. MARY AXE IS KNOWN AS ‘ THE GHERKIN ‘ BECAUSE THE PLANS LOOK LIKE GHERKIN IE: THE SLICE OF CUCUMBUR.  IT IS LONDONS FIRST ECOLOGICAL GREEN SKYSCRAPER.  IT IS ONE OF THE HIGHEST BUILDING IN LONDON.  IT WAS HONOURED WITH THE AWARD OF BEST BUILT PROJECT IN 2006.
THEGHERKIN PRELIMNARY DESIGN IDEA:  Breaking the hierarchy of solid rectangular boxes in the vicinity.  Offers minimal resistance to wind, improving the environment for people on the ground and reducing the load on the building.  The slim base reduces the reflections and increase daylight penetration.  The bullet shaped building responds to specific demands of small site area.

THEGHERKIN SECTIONS :
THEGHERKIN SUSTAINABILITY AND VENTILTION: Differing air pressures and double skin façade allow natural ventilation. Six spiralling light wells allow daylight. Windows are computer controlled and they open only when temperature is between 20-26 deg. And wind speed is less than 10mph
THEGHERKIN CIRCULATION:  Each of the two main stairwells contain 1037 stairs.  It has 23 lifts out of which 18 are passenger lifts.  It has well designed corridors with an professional ambience created by use of lightings and interiors.  Two special shuttle elevators serve the top floors of the building.
THEGHERKIN FOUNDATION :  Because of site restrictions and in order to create a monolithic foundation, all the piles were poured in one day.  No.of piles : 333  Length of pile : 9km  Dia of pile : 750mm
THEGHERKIN GENERAL STRUCTURE :  The structure is based on primary elements 1. DIAGRID 2. CORE  Diagrid is the main structure resisting horizontal and gravitional loads.  The core resists the gravitional loads.
THEGHERKIN DIAGRID : Aluminium coated tube steel. Series of two stories high. One full diamond is four stories tall. Diagrid is a series of triangle that combine the gravity and lateral support into one. It makes the building stiff, efficient and lighter than traditional high rise buildings It was later on adopted in many other buildings.
THEGHERKIN THE CORE :
THEGHERKIN CONNECTIONS : A special connector transfers the loads at NODES which are rigid ,monolithic and welded properly. The core has the rigid connections of steel beams and columns The diagrid has the rigid node connections at intersecting members.
THEGHERKIN CONCLUSION : THE BUILDING ALLOWS TO INVESTIGATE HOW A CITY DEVELOPS AND CHANGES OVER A TIME. IT IS GREAT EXAMPLE OF CONTEMPORARY ARCHITECTURE SURROUBDED BY MEDIEVAL CITY. THE EXCELLENTLY EMPHASISED STRUCTURAL DESIGN OF THE BUILDING MAKES IT STAND OUT IN THE VICINITY THE ARCHITECT MADE A GREAT EFFORT TO MAKE THE AMALGAMATION OF ARCHITECTURE , CLIMATE AND STRUCTURE.
THEGHERKIN MATERIALS : 35km of steel, 10000 tons are used. 24000 sq.m of glass is used on façade. Recyclable and recycled material was used wherever possible. The exterior cladding consists of 5500 flat triangular , diamond shaped glass panels.
