Precast Technology

• Technology Overview
• The process involves manufacturing concrete
  elements, stutural and non-structural , either in
  a factory or at site but not at its final
  location.
• In Brief This technology has a product
  centric approach against the process centric
  approach of conventional construction.
• Advantages
• Faster Construction Reduced Labor Dependency
• Superior Controlled quality construction
• Minimal Wastage of material less pollution
• Internationally proven technology, all processes
  are established

Technology Slabs
Parameters Solid Slab Hollow Core Slab Filigree Slab
Concept Pre-stressed concrete slab with continuous voids provided to reduce weight and cost Reinforced PC concrete floor slabs combined with in situ concrete Ensures a monolithic structure
Usage in countries Used extensively in UK, Middle East Used extensively in Germany, France
Thickness Can go till 75 mm Restricted to 150 mm minimum Can go till 90 mm
Span Ideally 4m spans Longer spans without immediate support Longer Spans can be achieved
Manufacturing Set up Forming/ Slip former/ Circulation Slip Former/ Extruder Separate Filigree set up/ circulation
Reinforcements used Quantity of Reinforcement is lesser More as triangular reinforcements is inserted.
Transportation Costly as weight is more Lesser weight makes the transportation cost lower with respect to solid slabs Low weight / volume, the transport costs to the construction sites are lower than for solid slabs.
Extra cost would have to be incurred
15
Technology - slabs
Parameters Solid Slab Hollow Core Slab Filigree Slab
On Site Erection
Process on site Very little concrete is poured on site No Support structure is needed on site Major concrete is poured on site during installation Light flex support structure is needed till curing
Lifting Weight Lifting Weight is maximum High tonnage cranes needed Lifting weight is more compared to semi precast slabs. So heavier cranes is needed. Lifting weight is considerably reduced So lesser bulky cranes is needed.
Time of Erection Comparatively more Least More than Hollow Core slabs
Service Aspect Less flexible More flexible

• Vision We would build sustainability into
  everything we do so that our profitable growth
  helps reduce inequality and rejuvenates the
  environment

Approach 1. Sustained Intervention in 5 focus
areas in the current year and conducting
stakeholder mapping and need assessment survey at
all locations to know long-term felt needs of the
community and draw a long term intervention
strategy accordingly. 2. Integrating
sustainability across the value chain of the
company. 3. CS funding is aligned to
business-shareholder aspirations and stakeholders
aspirations

• Focus Areas of Intervention
• Tata Affirmative Action across Employment,
  Employability, Education and Entrepreneurship
  development of SC/ST community
• Vocational Skill Development , Up-gradation of
  Schools and other Educational Initiatives
• Environmental Sustainability
• Local Infrastructure development
• Employee Volunteering/Synergizers
