Case Study - Tekla

Soaring Designs


TEKLA’s innovative BIM software is playing a key role in the expansion of Chennai Annadurai International Airport and modernisation of Sardar Vallabhai Patel Airport in Gujarat.


The Chennai Annadurai International Airport expansion and modernisation project in Tirusulam, 7 km south of Chennai in India, is a design-to-fabrication steel project carried out completely within Tekla BIM (Building Information Modelling) 3D software environment. The engineering and model dataware was used at the earlier stages of the project to take full advantage of early procurement and optimised use of material. The rapidly produced shop drawings and managing the project timeline were both accomplished using Tekla Structures software, which proved to be highly productive.


Advantages of Tekla Structures

By using Tekla Structures BIM software in the Chennai Airport Expansion project, the material wastage was reduced by 3.5-4 per cent and the productivity increased by more than 30 per cent. Additionally, the software was beneficial for early material procurement and optimised material usage During the fabrication stage, drawing details were derived from the Tekla model for fabrication and they were seamlessly used with in-house fabrication data package to produce NC files for use in CNC machines and to manipulate bill of material data. By using the centre of gravity from the Tekla model, the jigs were prepared for each segment of trusses to ensure perfect alignment and geometry during assembly.


The SVPIA makeover

Sardar Vallabhbhai Patel International Airport (SPVIA) is India's eighth busiest airport with daily movements of an average of 250 aircraft per day. It services the metropolitan areas of two cities in the State of Gujarat - Ahmedabad and Gandhinagar. The airport is located 8 km (5.0 mi) from the Ahmedabad Railway Station. The airport is spread over an area of 1,124 acres (4.55 km2) with the runway measuring 11,811 ft (3,600 m). The airport currently consists of four terminals: domestic, international, an additional terminal for secondary traffic and a cargo terminal. The Cargo and the domestic terminals use the same airside facilities but are physically separated on the landside, requiring a five-minute drive between them whereas the new International terminal has been constructed on the opposite of the land side of the domestic terminal and both the terminals are interconnected by an underground moving walkway. The airport was under renovation and now has 45 parking bays and both the international and domestic terminals have four aero-bridges each. The new terminal has been modelled based on the Singapore Changi Airport, a major aviation hub in the Asia-Pacific region. The new terminal has many firsts for the airport, including a half-kilometre-long moving walkway, which connects the two terminals, making the change over of flights hassle-free. Tekla Structures has been used for modelling and detailing of the entire structure. The main feature of the project was its shape, the shape of the rafter. Tekla Structures made it simple and easy to complete the project within specified time. The software was also used to model this complex framework, thus ensuring highly effective detailing and optimised fabrication of this exceptional structure.
