• 2001 RWP established as a technology
• company on site precasting since 2003
• Our aim is
• Mass elements faster and more ecconomical.
• Our customers are
• General Contractors and Precast Factories
• Two methods for on site precasting developed
• Battery Moulds for beams and columns
• Improved Tilt Up method

2.) Opportunities and limits of on site
precasting
Our opinion Mass elements (lt 3 h / m³) on
site Individual or labour intensive elements in
factories

• Why is on site precasting unusual today?
• too much space is needed
• not enough simplicity site installation,
  
• production details need to much attention
• keeping schedules in winter time is not reliable

In a nutshell Where does on site precasting
makes sense?

• Mass elements, about lt 3 h/m³, no
  individualism, no prestressing, no competition
  with automated factories

• Minimum size of a site
• 500 -1000 m³ of precast beams or columns
• (RWP Battery Formwork / Fold Away Formwork)
• 2000 4000 m² of walls / slabs for the
  Improved Tilt Up method

• Long production time rather than short spans
• Longer than 2 3 months, better 3 5 months

• Low Prices of concrete and rebar on site

• Prefered markets factories, warehouses, mayor
  housing projects, big sites, oversize elements

3.) Business proposals of RWP in the British
market
Our assets you can use Technology and / or
availability of German Craftsmanship

• We prefere to work with a partner for commercial
  and legal reasons on the basis of a simple
  contract.
• Partner Company / J.V. / Subcontracts

• Our range of services
• Production on site, starting 4 6 weeks after
  the order
• Production outside precast factories bridging
  capacity shortages, starting 3 5 weeks after
  the order
• Shop Drawings
• Selling RWP Battery Formwork / Fold Away Formwork

Summary

• For mass elements, on site precasting is a
  reliable alternative. lt 3 h/m³ as a guideline.

• RWP- Methods of on site precasting
• - high output on a small space
• - simplicity
• - reliable time schedules in winter

• Capacity and availability of German craftsmen can
  reduce production time.
