Tekla Software in practice:
Chennai Airport Expansion India
at the earliest stage a Chennai Annadurai International Airport expansion and modernization project in Tirusulam, 7 km south of Chennai, India, is a design-to-fabrication steel project carried out completely within Tekla BIM (Building Information Modeling) 3D software environment. Engineering and model data were used at the earlier stages of the project to take full advantage of early procurement and optimised use of material. Rapidly producing shop drawings and managing the project timeline were both accomplished using Tekla Structures software, which proved to be highly productive.
A Chennai Airport Expansion project, modeled by Yugasoft, is the Tekla BIM Awards 2010 winner for the best steel project. The new modernised airport will have a departure lounge on the first floor and one for the arrivals on the ground floor. Dramatic, hovering free-span and winglike roof structures, which are over 300 meters long, fold downward to form garden walls. The design of the terminal has a Finnish architect Saarinen-like quality to its sweeping rooflines, organizing passenger circulation around two sustainable gardens. Directly connected to the terminal is a new parking garage with a sculptural folding roof that welcomes travelers to the terminal with a green gateway. The new terminal buildings measures more than 140,000 meters. Its passenger capacity has increased from 10 to 30 million annually.
Project Facts s This state-of-the-art airport project covers an area of 65,000 square meters on two floors. Terminal buildings embody glass and steel to ensure natural lighting to minimise power consumption. The new domestic terminal covers 74,500 square meters. The 47,000 square meter multi-level car park offers parking on three levels in the basement and one parking area on the ground floor. The parking lot can accommodate 2,600 cars.

Time and cost savings C“I would estimate that using Tekla Structures software in the Chennai Airport Expansion project reduced the material wastage by 3.5 to 4% and increased our productivity by more than 30%,” says K. Mahadevan, head of Yugasoft. “To make work faster, at peak times, two modelers worked on the same server using the software in multi-user-mode. We estimate a significant cost reduction by using and implementing BIM in this project. The multiuser mode worked very well and saved us a lot of time and money,” he concludes.
Benefits in the fabrication stage A Drawing details were derived from the Tekla model for fabrication and they were seamlessly used with yugasoft’s in-house fabrication data package to produce NC files for use in CNC machines and to manipulate bill of material data. By using the center of gravity from the Tekla model, the jigs were prepared for each segment of trusses to ensure perfect alignment and geometry during assembly.

4% wastE reduction by early material procurement s Tekla Structures BIM software has been beneficial to Yugasoft for early material procurement and optimized material usage, reducing material wastage by 4%. As a group, Yugasoft has used Tekla software for the last three years. Complex geometry, both in concrete and steel structures, was the main challenge in the Chennai Airport Expansion project.

Our ambition is to multiply your potential to think and achieve big
W With an ambition to multiply its customersâ€™ potential to think and achieve big, Tekla provides a BIM (Building Information Modeling) software environment that can be shared by contractors, structural engineers, steel detailers and fabricators, as well as concrete detailers and manufacturers. The highly detailed as-built 3D models created, combined and distributed with Tekla software enable the highest level of constructability and production control. Centralizing building information into the model allows for more collaborative and integrated project management and delivery. This translates into increased productivity and elimination of waste, thus making construction and buildings more sustainable.
T With its software, Tekla Corporation drives the evolution of digital information models and provides thus more and more competitive advantage to the construction and infrastructure industries. Tekla was established in 1966, and today it has customers in nearly 100 countries, offices in 15 countries and a global partner network. Tekla software is used worldwide to model all types of buildings. Visit our website to read more about Tekla solutions and references for building and construction:
