Infosys's newest building in Electronics City in Bengaluru is using a pre-cast technology, one that can complete the 5.20 lakh facility in 7 months, compared to the traditional method that would have taken nearly two years.
The new block is a 3.5 lakh sq ft software development centre that will be able to seat some 3,000 people. It will have 1.7 lakh sq ft of multi-level car parking area.
The Rs 165 crore campus is being constructed by KEF Holdings at its first-of-its kind fully integrated pre-cast and prefabrication off-site construction facility in Krishnagiri.
KEF's fully-automated pre-cast unit can produce slabs, beams, columns, wall panels and staircases at its factory. These are then assembled at the client site.The prefabricated and modular unit is capable of producing prefabricated rooms, bathrooms and kitchens featuring modular mechanical, electrical and plumbing (MEP) services.
"Precast technology has evolved over a period of time. It will address many issues in terms of shortage of skilled manpower and constraints in pursuing construction with many buildings in the vicinity.
This technology requires only 5% of skilled resources compared to traditional construction techniques," said Ramadas Kamath, the executive vice president and head of infrastructure in Infosys.
He said that the fit-outs will be shipped through specialized trailers and assembled at the site during the day. "It's built in a modular way and can be plugged and pinned to the roof. It's tested for pressure and leaks," he added.
77-year-old structural design expert Spyros Tsoukantas is leading the structural design team for the Infosys project. So far Infosys has built campuses with a footprint 42 million sq ft with 4 million sq ft under various stages of construction. Infosys has also signed up with KEF for a second project that includes a 1.2 million sq ft SEZ building spread across 10 acres in Electronics City.
KEF has ten factories at its 42-acre Krishnagiri park which is seen as the world's largest fully integrated one-stop offsite construction destination. The unit builds on automation technology realized through robotic systems that are run by computer aided design (CAD) and computer aided manufacturing (CAM) software to eliminate wastage in the production line as well as reduce time and building costs.
Though pre-cast technologies comes at a slight premium to traditional construction techniques, the quick turnaround will help firms like Infosys recover costs in a shorter span.
"It's like assembling lego blocks. We can develop 100 units of columns, beams, walls and slabs every day in a pre-engineered manner at our factory," said KEF founder Faizal E Kottikollon. He said the company has invested Rs 400 crore in a hospital project in Kerala that is using pre-cast technology.
