calls for compliance with ECBC which are readily provide by precast
elements. Precast structures gain upto 23 potential points of Green
Building LEED Certification under the categories of innovation and
design process, sustainable sites, materials and resources, indoor
environmental quality and energy and atmosphere which make it
ideal choice for green buildings. There are several advantages of green
precast concrete such as corrosion resistant, durable, high compressive
strength, eco-friendly and good seismic behaviour.Materials used in green precast construction
The additives for the cement replacement like fly ash, GGBS, silica
fumes can be used in precast construction.The MS shutters or moulds
in place of wooden shutters or moulds can be used which saves lot of
trees on the earth. According to Shridhara C.N, Head-Technical and
Marketing, Preca Solutions India Pvt Ltd, using automation in supply of
concrete from batching plants to the moulds will reduce lot of wastage
of concrete. Using of curing compounds instead of water will save lot
of water. No plastering is required on the surface of precast elements.
It eliminates dirt at construction site and also eliminates unwanted
shrinkage cracks in the future. Directly painting can be done on the
surface of precast elements which minimise the maintenance cost
drastically.All precast elements shall be designed for two-hour fire ratings. The
hollow core slabs are very much energy-efficient products. These slabs
act as self-insulating for the heat transfer from open terraces. Even
insulated precast wall panels will reduce the usage of air conditioning
capacity drastically. The insulated walls will balance the temperature
inside the buildings. “All precast elements casting under stringent
quality procedures which results good quality of products. Also, all the
elements casting in horizontal MS moulds will avoid honey combing
while casting. Efficient compaction will increase the durability of
products,” said Shridhara.Shridhara C.N, Head-Technical and

lobal construction technology leader Trimble hosted its
flagship annual event for its Indian customers, Tekla User
Days (TUD) India, on 29th - 30th May at The Leela Palace in
Chennai. The theme of TUD 2019 edition was #TrulyConstructible
and is designed for industry professionals to interact, collaborate,
learn and showcase their projects to the larger audience. Giza – a
global leader in connection design software is a gold sponsor of this
two-day event. TUD is a highly anticipated annual conference and
is expected to draw over 200 industry leaders and professionals this
year. All participants got hands on experience of Tekla Structures
2019 with a host of new features and capabilities that makes
modelling quicker and easier.
Paul Wallett, Regional Director, Trimble Solutions, India and Middle East
said, “Every year, Tekla User Days brings to the Tekla user community
an unparalleled access to cutting-edge innovations such as the Trimble
Constructible process. With the introduction of Tekla Premier League,
the 2019 edition promises to be bigger and more immersive than ever
for the users in the country. Besides, we have an impressive line-up of
workshops, presentations and training sessions spread over two days to
provide a solid platform for participants to learn how to solve complex
real-world problems in construction by applying Trimble’s cutting-
edge technology. We are proud to provide this unique platform to the
stakeholders in the construction industry to learn, create, engage and
network”.Trimble hosted Tekla User Days 2019
