MIVAN formwork.

SYSTEM OF PRECAST CONSTRUCTION

An engineered system of building construction, namely “3-S” system was developed by B.G.SHIRKE CONSTRUCTION TECH LTD., for achieving, speed, strength, safety and economy in construction practices. The system involves structural elements such as pre-cast hollow column shells pre-cast concrete beams, light weighed reinforced cellular autoclaved concrete slabs for floor and roofs constituting the basic structural formwork. The “3-S” system involves activities for construction of building such as:

I. Cast in-situ sub-structure including foundations, stem columns, plinth beams, plinth masonry.

II. Erection of partial pre-cast components, jointing of these components using cast in-situ concrete with appropriate reinforcement.

III. Lying of reinforced cast in-situ screed over slab panels, construction of panels, construction of walling, flooring, plastering, water proofing etc.

Achieving the “3-S” system in the MIVAN formwork is quite easy. MIVAN formwork has got the unsurpassed speed of construction due to saving time for required time in masonry and plastering. The strength of raw aluminium is very less but when alloyed with other materials prove to be strong enough to use as a formwork . To ensure safety in the site, an integrated safety/ working platform is developed which ensures labor safety during erection and striking of the formwork. Economy is also one of the main factors of any system. The MIVAN formwork proves to cost efficient as it can be used efficiently for 250 times.

Present Technologies Available in INDIA

Some of the advanced technologies of formwork catering to the speed of construction are given below:

To name a few:-

1) The Prefabrication Technology

The Pre-cast concrete elements in roofs, floors and in walls have become more common as these eliminate shuttering; centering & plastering labor and saves material cost.

2) Tunnel Formwork Technology

It is a technology constructing large no of housing within short time using steel forms to construct walls & slabs in one continuous pour.

3) Outinard Technology

Outinard’s superior engineering, the use of high quality steel and High Performance quality control result in a vastly superior Wall Form system.

4) Mascon Technology

The Mascon Construction System is a system for forming the cast in-place concrete structure of a building. It is also a system for scheduling and controlling the work of other construction trades such as; steel reinforcement, concrete placement, and mechanical and electrical trades.
