Bridge Construction Tenders

[18.40]Supplying and laying of drainage composite for use behind walls, between two different fills, alongside drains of road, below concrete lining of canals etc. Geocomposite for planar drainage, realized by thermo bonding a draining core in extruded monofilaments with two filtering nonwoven geotextile that may also be working as separation or protecting layers. The draining three dimensional core will have a “W” configuration as longitudinal parallel channels. Minimum thickness to be 7.2mm, with two filtering UV stabilized polypropylene nonwoven geotextile of minimum thickness of 0.75mm characteristic opening size (O90) of 110 micron and tensile strength of 8.0 kN/m that will be working as separation or protecting layer, Geocomposite having in plane flow capacity of 2.1 L / (m.s) at hydraulic gradient of 1.0 and 20 kPa pressure and tensile strength of 18 kN/m , with mass per unit area of 740 gsm, supplied in the form of roll for easy transportation to site of work as per detailed specification all complete as per directions of Engineer in charge.

Construction of coffer dam made of earth and protected with earth filled gunny bags/ HDPE bags placed on either side slope of coffer dam of suitable dimension as per requirement at site of work to withstand the pressure of standing/flowing water of the drain in order to keep the working area free from incoming water/water coming through any broken water mains and subsequent removal upon completion of work upto DBL of the drain to the satisfaction of the Engineer-in-charge.
