Uniform 2022 Case Study

QATAR 2022: WHAT ARE THE KEY TECHNICAL CHALLENGES, AND HOW CAN THEY BE OVERCOME IN THE DESIGN OF A TEMPORARY STRUCTURE FOR AN INDOOR FOOTBALL TRAINING FACILITY?

Mr. Vinayak Dave (Assistant Professor, Saveetha School of Engineering)

ABSTRACT This study was to evaluate the proposed solutions over the technical challenges of Qatar World Cup 2022, which can be then used in order to set the design brief of a full pitch size indoor football training facility that incorporates changing facilities and capacity of 5000 spectators, but it will also have the ability of dismantling so as to remove it somewhere else in the world. Through literature survey, recommendations were provided to overcome issues of the extreme climatic conditions that will prevail
Bolted connections can also be more economic by 30 to 50 % of the total fabrication cost since it is simpler and faster process to install them on site but also it does not require any high skilled workmanship.

5 DESIGN OF FOOTBALL INDOOR
TRAINING FACILITY
The indoor football training facility is required to feature a full size football pitch in accordance with the FIFA World Cup rules. Therefore, the design must comply with Law 1 – “The field of play” of the Laws of the Game, which gives guidance on the dimensions and line markings of the field.

For the project under consideration, width of 68 metres and length of 100 metres were employed. The indoor football training facility is required to accommodate up to 5000 spectators. Therefore, seats from manufacturer Alibaba were chosen in order to estimate how many seats can be accommodated per row.

5.1 Conceptual
This results to ease and faster construction and deconstruction process. Moreover, in terms of constructability, the structure can be erected with no difficulties. As soon as, the grandstands have erected, arches would have attached to the columns of the grandstands and they would be temporarily supported at various points over the whole span. Finally, this solution satisfied the criteria set, however, it was decided at a later stage to make some amendments in order to improve it in some other aspects.

5.1.3 Final Conceptual Design
This concept involved two grandstands of capacity of 2500 spectators each; one opposite to the other, where the arches would be connected at the columns at the top of the grandstands. This can increase its value for money and its potential for getting sale since it would be able to accommodate two small teams in a championship game, considering that football in Middle East is not so widespread. It can also provide more space for facilities underneath of the grandstands. Tie cables were used at the supports of the arches in order to eliminate the horizontal force, which can induce moments.
