QUADRICON designs for Steel bridges being suitable for long spans, considerable savings can be achieved simply by eliminating intermediate pier/s and foundations as in case of RCC Bridges.

The long term assured Anti-corrosive treatment of Hot-Dip process of Zinc Galvanizing is unique feature of QUADRICON Steel Bridges which is feasible and cost effective mainly due to modularization of structural components of optimized sizes essential/viable for such treatment. This feature, however, may not be opted by you for bridges in Himalayan ranges as the air is free of pollution and the climate is also not tropical.

Substantial Savings in Earth Work and Protection Work of the Approach roads due to QUADRICON formation level (Carriage Ways) are very much lower than RCC Bridges (even up to 85%)

Since QUADRICON makes Super Structures in Modular System of components and assembles in progressive manner, QUADRICON can start assembly as soon as one side abutment (home side) is ready/completed

In case of constructing bridges by QUADRICON costs towards carriage of Sand, Rubbles, Chips, etc. for RCC bridges will be saved thereby damage to the existing roads to the bridge-site from either side can be avoided to great extent. The condition of the approach roads to the bridge site, if they are not up to the mark, then  truck-loads of construction material  cannot be reached directly. Other means of transportation of construction materials will have to be adopted which delays the completion of the project.

Steel Bridges will be Eco-Friendly and will have much longer Service life (even 100 + years)

QUADRICON super structure’s frames and connectors are made from Tested High Tensile Steel (Micro-Alloy Steel) and the quality controls are performed at material manufacturing stages as also in the Pre-fabricating shops. While in riveted/bolted bridges (also RCC bridges) carrying out quality controls at site or at pre-fabricating shops is very complicated and could be a Herculean task and still remains doubtful.

It has been regularly observed that in plain Himalayan regions river meandering is very common sight by which the course of river changes which makes the bridges redundant or require River Training. In such cases QUADRICON bridges which are not on fixed fasteners (like Rivets, etc.) can be fully relocated, upgraded according to the increase in traffic volume  and will not be a waste

Re-cycling of QUADRICON bridges will be possible at the end of Service Life.

In case of QUADRICON bridges, repairing and replacement of components can be carried out under traffic conditions whereas in case of RCC bridges no such condition would be applicable.

QUADRICON bridges can be insured for Service life, at a time, of over 25 years including replacement called for due to natural disaster

QUADRICON bridge components are assembled together without any Fixed Fastener (like Rivets) and are flexible through QUADRICON’s unique invention of world-wide Patented “Shear Connectors” which improves the life span of QUADRICON bridges substantially, while the life span of RCC   Bridges and conventional Riveted Steel Bridges are much less when compared with QUADRICON bridges. In addition, these conventional Riveted Bridges and RCC Bridges require continuing periodical inspection and maintenance such as re-painting and replacement of rivets as in case of conventional riveted bridges and incase of RCC bridges epoxy treatment for exposed zones of re-inforcement (It is an usual phenomenon).

For construction of RCC bridges soft water (like drinking water) has to be used which is in short supply all over the country even for human consumption. Therefore it will be great injustice to use large volume of soft water in construction work. This was one of the main issues deliberated in recently held international seminar at Bali.

It is pertinent to point out that the RCC Bridges constructed during the periods between the First and Third Five Years Plans, most of the RCC Bridges have gone in distress and have resulted in instances where heavy repairs have to be carried out even by diverting traffic at huge costs.
