SOLUTIONS___________________________________________

OPTION 1

TEMPORARY STEEL STRUCTURE

This includes the fabrication and erection of MS Structure which contains an

assemblage of Square Box Sections in the form of Columns , Rafters , and Purlins .

The Structure is then covered by Powder Coated Galvanised Iron Corrugated

Sheet.

The structure design of the system is as follows :

TYPICAL SECTION

Calculation of Steel

The design Uses following ISMB Tata Steel Iron Sections :

1. ISMB- 80 x 80 x 3.2 Square Box Section2. ISMB - 80 x 40 x 3.2 Rectangular Box Section3. ISMB - 50 x 50 x 3.6 Square Sections

As per the structural calculations , the amount of Steel used per 100 Sq. M of Area is

as Follows :

1. ISMB - 80 x 80 x 3.2 : 354.81 Kg2. ISMB - 80 x 40 x 3.2 : 501.63 Kg3. ISMB - 50 x 50 x 3.6 : 937.24 Kg

Hence Total Steel used per 100 Sq.M : 1793 .68 Kg

Cost of Structure : 100 Rs / kg

The above cost includes :

Basic Material Cost Labour Cost Fabrication Cost , Transportation Cost Erection Cost Coat of Base Primer to the Structure Coat of Black paint to the Structure

Hence Cost of Steel Structure is : Rs 179368 per Sq. M

: Rs 179 per Sq. Ft

Calculation of Roofing

The design uses Powder Coated TATA STEELs corrugated iron sheet .

Cost of Roofing : Rs 55 per Sq. ft

The above cost includes Material Labour

Transportation Erection and Fixing

Total Cost of Structure per Sq. ft : 234 per Sq.Ft

OVERALL COST for the society : 234 x 16960 Sq Ft

: Rs 3968640

OPTION 2

MEMBRANE WATER PROOFING

This includes the putting up of TORCHSHEILD membrane on already existing roofing

surface. This is a 3mm thick heavy duty membrane which is even used in swimming

pools . So it can be very safe in our case.

Specifications are as follows :
