PRECASTING
A Precast Building consists of all the same elements as a conventional building which
includes floors, roofs, walls as well as beams, columns and stairs, the only difference is that
these elements are manufactured in a controlled environment and transported to the site for
Erection, Connection and Commissioning.
The industrialization of Construction Industry implies the change of the whole building
process. The need to build better, faster and in an economically viable way led to the
precasting technology to attain a strong foothold in the industry. Proper planning, Detailing
design & Coordination of the project prior to construction activities to be considered to
minimize the changes at site.

A. HOLLOW CORE
A Hollow core slab, also known as avoided slab or hollow core plank, is a precast slab
of prestressed concrete typically used in the construction of floors in multi-storey buildings.
They are widely used throughout the world as flooring and roofing solutions.
Teemage hollowcore slabs are nominally 1200, wide and are available in thickness of
150mm, 200mm, 250mm, 300mm and 400mm. All the slabs are cast with high strength
prestressing cables to provide the load carrying capacity
Hollow Core
Features & Advantages
� Varying thickness of (150-400)mm available and large spans up to 18m can be
obtained at costs which are lower than conventional flooring systems.
� The casting is sequenced in such a way that every floor of building is stored and ready
to be delivered for installation as quickly as required at the site.
� Expensive formwork and propping is eliminated thus improving productivity and
access within the site is vastly improved.
� Once erected, Hollowcore slab can be used as instant work deck and thus decreases
the delay due to curing or removal of formwork.
� The hollow cores reduces the overall weight of the structure thus economizes the
foundation system.
� The top surface is roughened for accepting a nominal screed of concrete or smoothens
for direct installation of floor tiles.
� The speed of erection is unlike any other system, with a crane and a small crew at the
site, 4000 sq.ft of slabs can be placed in 8 working hours.
� Hollowcore is considered as a Green Building Product because of the efficient use of
materials and resources and also because of its reuse and recyclable properties,

Managing elemental production of (Pre-stressed Hollow core slabs, Precast Solid slabs,
Precast Wall panels, Precast Columns & Beams, Prestressed Beams, Precast Stairs, Boundary
Walls, Trenches)
Quality Control
Following are the process done by QC
a. Mould Checking
Based on programme given by planning department respected mould get prepared
and checked by QC.
b. Reinforcement
Programme for fabrication is issued to respected person based on that they prepared.
c. Pre Pour Check
Before concreting mould and reinforcement details get checked by QC by referring
piece drawings. Respected person must approve for concreting.
d. Post Pour Check
After Concreting and lifting for curing, QC persons must check that, it should be
suitable for loading operation or not. If not proper rectification operation should noted and
inform to respected person to do so.
Final Inspection
Here based on the piece drawings element should be checked and approved to next
stage. If any correction exists, rectification work should be done before going to next
stage.
Loading

Report on Erection process occurred over M/S Garson’s Private Ltd. – Hosur
Visit to M/S Garson’s Pvt. Ltd. For a week (23.7.14 to 28.7.14) to know about erection
process and other process done over there. Following are the process held there,
� Erection
� Civil
� Waterproofing
� Electrical & Tile laying
A. Erection
a. This process is composed of unloading and erection, done by crane operator. Layout
for the work gets prepared by technical team. Target for the whole work gets fixed. To reach
the target whole team work spontaneously.
b. Erection work mainly depends on elements that they getting over the site. Also
sequence of elements that they want to get. If they working on Zone 2 Ground floor Hollow
core, getting element of 1st
floor they won’t do work. So, loading from production plant get
planned based upon the work done over the site.
c. Erection elements composed of column, beam, hollow core slab, stairs, wall etc.
Erecting column, it takes much time with reference to Total Station. Levelling for the column
is given by surveyor based upon that column erection process continued. Based on that beam
and slab erected.
d. While erecting level for the element is given by Sim pad, is a kind of element used
to level the element and act as a vibration absorber during earthquake.
e. Erection of beam and slab easy after proper erection of column. During erection
must concern about the insertion of dowel hole and dowel rod and respected element
levelling. Levelling is given with the help of jack.
After erection following process is to be done for a respected element,
� Level check by plumb
� For column to column: distance check by laser meter
� Proper level parallel to other element given with help of jacks.
� For walls: Gap between two walls get closed by,
1. Rod insertion between the loops.
2. Filling grout & plaster with the help of foam.
3. after 3 to 4 days removal of jacks.
Likewise for all elements respected process get followed.
B. Civil Work
a. Civil work is composed of erecting footings, screed concrete, and ramp concrete,
patch works etc. Separate Site engineer allotted to supervise the work. Based on the
respected layout drawings work gets allotted to the workers.
b. Also before and after erection of precast elements respected civil works get done if
needed.
C. Water Proofing
It is to be done to the back side of wall
D. Electrical & Plumbing
Sealant Sealant with border Polyurethane sheet
Recommendations for an efficient work
� Proper element finish makes the work comfort
� Proper checking of element (dimensions, level, finish etc...) makes work perfect.
� Proper checking of dowel rod dimensions makes the erection process quicker & easier.
� Proper planning of loading of an element to site for erection makes the work easier.
