On 9/01/2015 I went to visit Olympic stadium to my friend, Civil Engineer working on regeneration project ‘Balfour Beatty’ Martin Silickis. He escorted me through the site and showed the latest addons to the building, such as recreating larger roof structure using PVC fabric and stressed cable system and exterior entrances by expanding the entrance, creating foundation with large lift shafts and stairs for crowd guidance

the PVC-coated polyester fabric external wrap, the oversized bunting, an essential component of Populous’ medieval fête-like concept, is currently being tendered by LOCOG. With 10,000 tonnes of steel, it’s the lightest ever Olympic stadium To ensure the longevity of the stadium a premium was placed on sustainability and legacy. The stadium had to be flexible enough to convert into a smaller venue postGames whilst also acting as a focal point of the Olympic Park and for the regeneration of Stratford, East London. This brief outlined a stadium that could be reduced from 80,000 seats to 25,000 seats after 2012, a scale of post-games conversion never before attempted and one that offered significant design and construction challenges. Following the design development phase the final design included: A permanent 25,000-seat sunken bowl. A 55,000-seat tier of demountable terracing. A tensile fabric wrap skin to enclose the venue. A structurally independent compression truss, which supported a cable net roof, lighting towers and ceremonies tripods. The roof structure was independent of the main stadium bowl structure and consisted of a cable net roof design formulated in the shape of a tensioned ring similar in form to a bicycle wheel. The central node (hub of the wheel) is expanded to create a 600m circumference inner tension ring. This was attached to the top and bottom chords of a compression truss (the outer rim of the wheel) by 28 sets of main suspension cables (the spokes). Pre-stressing the two elements of the structure against each other holds the roof 40m above the field of play.
Environmental factors: there are no clear evidence of CO2 emissions but the fact that 90% of soil has been recycled and reused gives an enormous saving of pollution. By clearing th underdeveloped site there was an interruption in wildlife thus causing certain species to leave, but recreating the wildlife for the games, certain species has ben brought in site Formal factors: the building is constructed based on engineering decisions and of the use of most efficient amount of material, thus the building has nice formal and spatial qualities
The compression truss, which is structurally independent of the rest the bowl steelwork, supports the roof and, uniquely for a stadium of its kind, the 14 huge lighting towers which sit on top of the inner tension ring. A tensile fabric, which consisted of post-tensioned woven yarn and a PVC coating was attached to the cable net to form the roof. The tensile fabric was a Ferrari membrane which was cut and high frequency welded together to form 112 panels. The roof was two-way symmetrical, resulting in 28 different pattern designs The load from roof structure is dispensed The main construction materials are steel reinforced concrete and steel pipes. The concrete with steel is used via structural columns that lead into the literally almost everywhere in this building. ground to the pile foundation. The building is designed using structural engineering for more efficient and spatial qualities. The stadium is the lightest of its kind and provides sustainable solution policy in achieving it.

A catalyst for positive change Etihad Stadium Melbourne 2000 imited space meant that 2,500 car parks had to be built underneath the stadium, and the connection of a sophisticated public transport system was able to link the stadium to a wide range of shops, restaurants and hotels. The 53,000 stadium boasts the first retractable roof and moving tier technology in a large stadium in the Southern Hemisphere, combined with a natural turf playing surface. The moving tier technology means multi-functionality, intimacy and flexibility for both sport and entertainment, maximizing the experiences of all spectators, no matter what the event.
Europe's most successful Football Stadium Emirates Stadium London 2006 A site was identified, close to the existing stadium – the challenge was to create a master plan which could fit the new stadium on this difficult site, deliver the maximum area for residential development and meet the local council’s requirements for the provision of social housing. The curved glass, concrete and steel mesh paneled facades of the stadium rise between the terraced streets, offering a series of dramatic views of the venue to the approaching visitor. Above, the roof is supported on just eight cores, allowing the slender roof plane to float above the robust facade of the building below. Success in building the stadium increased the revenue by 3 times for Arsenal FC and UEFA defined it as the success model for other clubs to follow

N The Olympic stadium is constructed on the island with canals surrounding it. This gives controlled secure access in the building via bridges around the island. The Olympic stadium is the key building in the landscape and all the paths lead to it. In relation to Canary wharf it sits on axis.
Brief- The aim of the team was to design the most sustainable Olympic stadium to date and reduce the amount of steel and concrete needed, making it one of the lightest stadia of the modern era. Challenges- The challenge in building a stadium for a specific event lies in creating a structure that is both temporary and permanent. This is the essence of the London 2012 Olympic Stadium. The 80,000 seat venue was designed to be transformed post-Games to a 25,000 seat venue. Design Challenge- To achieve a balance between the immediate needs of a large Games stadium against a long-term, small-scale venue, we embraced the opportunity to develop the architectural language of venue design. We progressed a new theory of ‘embracing the temporary’, exploring form, materials, structure and operational systems to bring a structured palette of elements into a cohesive design. This promotes possibilities of transformation after the Games down to a minimum 25,000 seat venue form.

Success- The London 2012 Olympic Stadium sets a new benchmark in sustainable design for sports stadia and changes the face of stadium architecture. It’s a new approach to how we think of sustainability, which reflects the city’s compelling commitment to legacy. The key sustainability criteria of ‘reduce, re-use and recycle’ were adopted to create a compact, flexible and lightweight design. The main stadium structure is light and elegant and uses only ten per cent of the steel weight used for the Beijing stadium. The fabric roof is based on the engineering principles of a bicycle wheel and was redesigned to enable the use of ‘found’ steel, while the facade of the building is composed of a lightweight fabric ‘wrap’, which twists at the base to allow entry to the seating bowl.
