Water Resources Department Tender

Supply of Geo-Textile Bags, Type C of Size 1.50 m × 1.00 m, inner dimension made of composite layers of geotextile as per specifications below: Woven Geo-textile for the outer cover. The woven geo textile is woven with UV resistant slit film tape fibre with MAVR values of the following properties. Geo-textile used to manufacture geo-textile bags should have high mechanical properties for enhanced durability along with enhanced puncture, abrasion and U.V. resistance characteristics. Geo-textile should be inert to biological degradation and resistant to naturally encountered chemicals, alkalis, and acids. Weight (ISO-9864/ASTMD 5261) ≥ 250 Gms/Sqm.  Tensile strength (MD) (ASTMD 4595) ≥35 kN/m.  Tensile strength (CD) (ASTMD 4595) ≥ 35 kN/m.  Tensile Elongation (ASTMD 4595) ≥ 5% & ≤ 30%.  Grab Elongation (ASTMD 4632) ≥ 5% & ≤ 30%. Tensile strength (ASTMD 4632) = 1.5 kN.  UV resistance (ASTMD 4355) = 70%/500 hrs. Non-woven Geo-textile for the inner layer. It is needle punched non-woven geo-textile made of 100 polypropylene staple fibers which are formed into a random network for dimensional stability. It should resist UV degradation, rotting and alkalis.  Weight (ISO-9864/ASTMD 5261) ≥ 300 Gms/Sqm.  Tensile strength (MD) (ASTMD 4595) ≥ 12 kN/m  Tensile strength (CD) (ASTMD 4595) ≥ 12 kN/m  Tensile Elongation (ASTMD 4595) ≥ 5% & ≤30%  Grab Elongation (ASTMD 4632) ≥ 5% & ≤ 30%  Tensile strength (ASTMD 4632) = 1.5 KN  UV resistance (ASTMD 4355) = 70%/500 hrs (Bags are to be supplied of 100 numbers or part in a bundle, properly packed with name of Manufacturer and Batch Number is to be marked on each bag with “WRD Govt. of ASSAM” to be printed on each bag and mentioning properly the GSM and type of Geo bag polymer. Test Certificate from approved NABL accredited and ISO Certified Laboratory should invariably be submitted against each batch of material)

Carriage of Geo Bags type-C of size 1.5x 1.0 m including loading & unloading, Stacking, etc. complete and including hire charge of truck with driver and handyman cost of POL etc. completed as directed.

Filling and laying of Geo bags type-C of size 1.5m X 1.0m including excavation of sand/silt from flood plain or adjacent chars within a distance of 90m of the work site, filling geo bags with sand/silt having minimum weighing 330 Kg and minimum volume 0.221 cum after filling , double locking chain stitching the mouth of the filled bags with polypropylene thread by power driven double needle double stitched machine, stacking the same in batches of 100, carrying the same to the dumping site including all handling charges and local carriage within a distance of 150m and laying properly as directed. (sand/silt, Geo Bag and Polypropylene thread will be supplied by the department free of cost) With Engine Boat
