Fast Flats
Fast Flats
THE application of precast technology is all set to revolutionise the construction of residential towers in India. In fact, this could well be the future of ultra-rapid mechanised construction.
This is especially after L&T recently demonstrated the immense utility of the precast technology in its Mission 96 – that is by constructing a 12-storey residential tower containing 96 flats in just 96 days!
The tower, constructed in Navi Mumbai, is part of an initiative by the City and Industrial Development Corporation of Maharashtra (CIDCO) to build housing for the people with low-income. In all, CIDCO is building some 23,432 residences at Bamandongri, Kharkopar and Taloja in Navi Mumbai and the 96 flats are among them. This project is under Package-IV of the Pradhan Mantri Awas Yojana.
The magnitude of the project was large, covering a built-up area of 64,000 sq ft. It involved production and installation of 1,985 precast elements of the superstructure, along with architectural finishes, mechanical, electrical and plumbing works. The large concrete panels used owe their superior quality to the controlled production in a factory environment.
B&F Fast, a special unit of the Buildings & Factories arm of L&T, commenced the construction work
on 4 April and hit its first milestone of 12 floors in 36 days. That’s an unprecedented 3-day floor construction cycle as compared to the industry norm of 8-12 days a floor.
The precast construction made it possible to initiate internal finishing works in 10 days – as soon as the third floor was completed. And that’s how L&T, on 9 July, homed in the ambitious target of constructing 96 flats in 96 days.
According to Mr M V Satish (Whole-time Director & Sr EVP – Buildings at L&T), apart from the precast construction technology, the project team also leveraged digital technology to achieve the rapid-pace construction. “We adopted the ‘concrete maturity’ method to monitor the development of concrete strength in real time using digital meters and monitored progress using ‘digital twin’ approach with a Building Information Model developed for
the project,” he says.
CIDCO authorities are overjoyed with the feat that L&T achieved in the project. “Great to see the record-making process by L&T. This will pave the way for the use of such technologies and excellent shopfloor management in the future,” the Jt MD of CIDCO, Mr Ashwin Mudgal, said at an event held to showcase the completed tower.
The feat has also earned appreciation from famed architect Mr Hafeez Contractor. “L&T, which pioneered aluminum formwork construction in the country and changed the face of the residential sector, has been instrumental in driving precast technology to further achieve material sustainability and speedy construction”.
L&T’s focus on prefabricated pre-finished volumetric construction would help meet India’s growing demand for housing, he added. Prior to this, in March this year, L&T had constructed a 7-storey Flight Control System Integration Centre for the DRDO in Bengaluru. Time is money. Thus, every minute saved is money earned, especially if the job in question has an economic aspect.

Who keeps the world’s highest motorable road motorable?  The  Border  Roads Organisation (BRO) – aided by machinery like L&T’s sturdy wheel loaders.
A wheel loader is a heavy vehicle that loads and carries materials across a work site and are integral to road construction and upkeep. To strengthen road infrastructure in the northeast, north and north-west, BRO recently ordered 70 WL9020 wheel loaders manufactured by L&T Construction Equipment Ltd (LTCEL). Out of this, 25 have already been deployed.
These wheel loaders are now working on the world’s highest motorable pass – Umling La in eastern Ladakh. At 19,024 feet – the pass is higher than Mt Everest’s North and South base camps. There, the temperatures drop to minus 40 degree Celsius and the oxygen level is almost 50% lower than that at sea level.
The L&T wheel loaders are ideal for such harsh terrain. The sturdy machines are fitted with ‘cold starting kits’, enabling them to work in sub-zero temperatures. Part of L&T’s contribution to Aatmanirbhar Bharat initiative, these machines were designed and developed by LTCEL’s Product Development Centre at Coimbatore. In line with the Government’s vision to promote local manufacturing, over 90% of their content is indigenous.
The range of LTCEL’s road construction equipment is large and diverse. It includes vibratory compactors, pneumatic tyred rollers, asphalt pavers, skid steer loaders, wheel loaders and hydraulic excavators, as well as attachments such as crusher buckets and slope compactors.
LTCEL also manufactures high-precision hydraulic components, customised systems for applications in construction equipment, industrial machinery and other engineering sectors.
The company owes the high quality of its products to smart manufacturing technologies such as CNC machines, welding robots, precision  machinery  and  a multi-modal assembly line. It is ISO 9001, ISO 14001, and ISO 45001 certified and shares a legacy of continuous innovation in manufacturing know-how and technology.
L&T Construction & Mining Machinery business (CMB) markets and provides after-sales support for all LTCEL machinery.
