Dry construction for hotel industry
Prashant Zanwar
The Indian economy is booming and the demand in commercial and industrial sectors
has led to a similar situation in the hospitality industry with many international
hotel chains in queue to invest and acquire management control.
Trends are changing in all the sectors and civil construction industry cannot
remain aloof. With many more players coming in looking at the huge demand, there
is an urgent need for speedy, cost-effective and eco-friendly construction techniques
which can help to achieve faster return on investment. How can it be achieved?
Since post-tensioning of slabs available in India 1996 onwards has changed the
scene in commercial building by providing larger heights from floor to floor
quicker to accommodate the services property and larger column spacing. This
change was really accepted with dramatic speed at which you are able to create
the shells and start the return on investment though it is expensive when compared
with conventional construction. Same has been the case as regard to glass facades
though the technology is not competent enough for the Indian climate.
This has changed the pace and speed of constructing RCC shell for commercial
building including hotels and hospitals. The time has come to adopt six decade-old
proven dry walls as the complete replacement to brick/block walls partition/enclosures.
Dry wall is the construction typically done with a cold form GI section with
gypsum plasterboards, cement boards, calcium silicate boards, magnesium silicate
boards from both sides to create composite kind of construction and the cavity
in between provides you enough space to accommodate electrical and plumbing
services.
The weight of the construction reduces the dead load on RCC shell to the tune
of 80 per cent, which in turn helps you to reduce the cost of steel and concrete
towards the shell. Below is some comparison of some basic material, internal
walling and partition.
The overall speed of construction helps you to reduce the construction time
with a conservative estimate by 30 per cent with respect to estimated project
schedule.
Fortunately, there is an internationality-acclaimed manufacturer of plasterboards
calcium silicate boards, magnesium silicate boards, cement boards available
in India either directly as manufacturing base as imports or in technically-collaborated
way. Along with this, required skills are available in our country to complete
the works as per the standards.
Advantages of dry wall over brick work and plaster
Work is carried out as per the international building norms i.e fire, safety,
acoustics and weather. Calcium silicate boards, magnesium silicate boards, cement
boards have good performance when in contact with water.
The cost of dry wall is slightly higher in comparison with brickwork and plaster
but dry wall has low/negligible dead load which reduces the overall construction
cost. Traditional brick manufacturing has so many adverse impacts on environment
such as using fertile soil, improper fuels used for kilns, pollution, uncontrolled
sloppy manufacturing process, child labour, etc. The dry wall material is manufactured
in a controlled atmosphere with stringent quality norms.
Easy material handling and speedy construction, clean and
neat site working condition, convenient in existing structures which are occupied
and are in operation and looking up for upgradation and renovation. Highly compatible
with RCC and steel structures as well as external facades. Cavity between the
walls can be used to run services like electrical and plumbing without recessing
walls. Non load-bearing and load-bearing walls can be designed with all the
above advantages. To conclude, opting for dry wall certainly makes good business
sense in terms of time, cost and quality for achieving faster returns on investments.
