Irrigation And Flood Control Department Tender

Design, Fabrication, Erection, Installation, Testing, and Commissioning of a vertical Sliding lift gates system on a seasonal Nallah with a clear waterway width of 17 feet and a height of 5.5 feet and regulatory gate of 5.5 feet width and 5.5 height. The gate and allied components shall be designed and installed in strict compliance with IS 5620 (Code of Practice for Installation of Vertical Lift Gates) and other relevant Indian Standard codes. • The work includes design of the gate frames (As per IS 2062), Embedded parts like guide rails and guide frames (As per IS 456 and IS 1905), Bearing Plate (As per IS 6911 or IS 210 or IS 8500 or IS291), Seals (As per IS 4622 or IS 2004 or IS 6911 or IS 291),Horizontal and vertical stiffeners and anchorage system, Design of Gate leaf (As per IS 2062) considering water pressure, gate weight, and operational loads; design of gate railing and other safety components; and design of the manual operation system comprising of appropriate hoist mechanism, gear system, and handwheel or lift mechanism. • The works also involves excavation and preparation of the foundation for the gate structure, i.e columns including guide frames and anchorage system shall be carried out (As per IS 456 and IS 1905) along with platform for operation of gates and other civil works. Casting of reinforced concrete foundation and anchorage blocks as per design shall be done. Erection of the gate frame, including guide rails and guide frames, shall ensure proper alignment and plumbness. • Installation of the gate leaf, including the sealing system and any necessary counterweights shall be carried out. The manual operation system, comprising the hoist mechanism, gear system, and handwheel or lift mechanism, shall be installed. Gate railing and other safety components shall also be installed. The work also includes earth works and concrete works for the side retention walls adjacent to gates. • Testing and commissioning shall include leakage tests to check the sealing integrity of the gate leaf, load tests to verify structural integrity and operational performance under design loads, and operational tests to ensure smooth and efficient manual operation. Final commissioning, including adjustments, calibrations, and trial operations shall be performed. • Preparation of operation and maintenance manuals, as well as training of operating personnel, shall be part of the scope. Adherence to IS 5620 and other relevant Indian Standard codes, quality control measures (material testing, inspection, documentation), and necessary approvals and certifications shall be ensured throughout the project.
