LHPs are model housing projects with houses built with
shortlisted alternate technology suitable to the geo-climatic
and hazard conditions of the region. This will demonstrate and
deliver ready to live houses with speed, economy and with better
quality of construction in a sustainable manner.
The period of construction is maximum 12 months from the date of
handing over of sites to the construction agency after all
statutory approvals. Approvals will be accorded through a fast
track process by the concerned State Government.
These LHPs shall serve as LIVE Laboratories for different
aspects of Transfer of technologies to field application, such
as planning, design, production of components, construction
practices and testing. etc. for both faculty and students, Builders,
Professionals of Private and Public sectors and other
stakeholders involved in such construction.
Six Technology providers have been selected through rigorous online bidding process for construction of Light House Projects (LHPs) at six different locations in six states.
LIGHT HOUSE PROJECT - RANCHI, JHARKHAND
TECHNOLOGY: Precast Concrete Construction System – 3D Volumetric
An already established System for building
construction in Europe, Singapore, Japan &
Australia, this 3D Volumetric concrete construction
is the modern method of building by which solid
precast concrete structural modules like room,
toilet, kitchen, bathroom, stairs etc. & any
combination of these are cast monolithically in
Plant or Casting yard in a controlled condition.
These Modules are transported, erected & installed
using cranes and push-pull jacks and are integrated
together in the form of complete building unit.
Subject to the hoisting capacity, building of any
height can be constructed using the technology.
construction in the project here begins with keeping the
designed foundation of the building ready, while manufacturing
of precast concrete structural modules are taking place at the
factory. Factory finished building units/modules are then
installed at the site with the help of tower cranes. Gable end
walls are positioned to terminate the sides of building. Pre
stressed slabs are then installed as flooring elements. Rebar
mesh is finally placed for structural screed thereby connecting
all the elements together. Consecutive floors are built in
similar manner to complete the structure.
90% of the building work including finishing is complete in
plant/casting yard leading to significant reduction in
construction & occupancy time.
controlled factory environment brings resource optimization,
improved quality, precision & finish.
required concrete can be designed using industrial
by-products such as Fly Ash, Ground granulated blast furnace
slag (GGBS), Micro silica etc. resulting in improved
workability & durability, while also conserving natural
resources. In this project Ground granulated blast furnace
slag & silica fume is being used in concrete
smooth surface it eliminates use of plaster.
monolithic casting of walls & floor of a building module
reduces the chances of leakage.
system has minimal material wastage (saving in material
cost), helps in keeping neat & clean construction site and
dust free environment.
- Use of
Optimum quantity of water through recycling.
- Use of
shuttering & scaffolding materials is minimal.
weather construction & better site organization.
