Providing ,arranging and erecting 50mm dia M.S. pipe cup lock shuttering arrangement above the ground level upto the height given below. The girding arrangement of cup lock system should have 2.50 meter 3.00 meter long coupling pipes and 0.90mt long lacer pipe (Horizontal bracing pipes) reconnected in both ways so as to make a square grid of size 0.90x0.90 meter in plan. The Horizontal bracing and lacer pipes should have a maximum spacing of 1.50 meter c/c both ways. The bottom of the coupling pipe must rest over a firm support at ground. the shuttering plates of 900mmx600mm size duly braced by angle supports and should rest over 50mmx50mm size wooden logs supported by 75x40x6mm size channels and U-Jacks made of M.S.25mm dia steel bars with adjustable thread and lock arrangement placed at a spacing of 0.60 meter c/c. The whole arrangement should be duly shored from ground by U-Jacks and lacer pipes to prevent any lateral movement during casting of slabs. Additional support as per direction of engineer in charge are also to by provided wherever felt necessary. The work would include transportation of material erecting the whole grid structure, bracing both way, shoring, leveling of shuttering and removal of form work complete as per direction of Engineer in charge for all the floors upto the height of:-Upto 6.63 meter height
