New Delhi: In A First, ‘Dry Construction Technology’ Being Employed To Complete Office Buildings In Record Seven Months – Swarajya

This helps reduce the construction period.

CPWD officials said they are using special bamboo flooring in these projects which are being brought from Meghalaya.

According to CPWD, the projects, started in August this year, have already made 35 per cent physical progress. This technology has not been used in such big projects.

Its success will demonstrate that construction of buildings in cities like Delhi can be done causing hardly any damage to the environment. It takes at least two years to construct such a building complex using conventional technologies.

These two office complexes can accommodate nearly 15,000 employees.The employees, who are currently occupying office space at hutments near South Block, will be shifted here.

The vacated areas will be utilised for construction of a new PMs Office, PMs residence and for accommodating SPG employees.

Officials said the facade of the buildings will resemble the Lutyens style and terracotta tiles will be used for this.

They added the expeditious construction was possible because of 'dry wall construction technology', which uses light gauge steel frames (LGSF) for external and internal walls.

These frames are covered with cement fibre boards on the outer side of external walls.

Cement fibre boards, coupled with gypsum boards, are used for interiors. Rock wool is filled in LGSF sections for thermal insulation.

This does not need water for curing of any concrete or cement plaster work and hence, a lot of water is saved.

Moreover, to increase fire resistance of the structures, vermiculite cement plaster is being done on the steel structures.

Due to this, the structures can withstand for two hours in case of a fire.This finish is not only aesthetically appealing, but also very durable and maintenance-free for years.

This type of faade has a very low effect of ageing, fading and discolouration over time due to their low water absorption properties and high firing temperatures during manufacture.

It also provides acoustic insulation from outside, which reduces noise levels by 10-20 per cent.

Pollution control measures have been adopted at both the sites. The air and noise pollution is being monitored round-the-clock with sophisticated equipment.

Thermal comfort comes from ventilated terracotta tile faade which also reduces the use of energy for air conditioning as well as for heating.

The ventilated installation system reduces the solar heat gain of the building from the external facade, thereby reducing energy requirements for cooling.

These measures include 10 metre-high barricading all-round the perimeter, regular sprinkling of water on the open areas, use of anti-smog guns, controlled deconstruction measures, covering of all debris, sand, excavated soil and aggregates with suitable fabric sheets, covering of trucks/dumpers transporting the debris outside the site, and cleaning of tyres of all vehicles.
