4.3.1:Centering and shuttering including strutting, propping etc. and removal of form work for:Foundations, footings, bases for columns

5.9.1:Centering and shuttering including strutting, etc. and removal of form for:Foundations, footings, bases of columns, etc for mass concrete

26.28.2:Chipping of unsound/weak concrete material from slabs, beams, columns etc. with manual Chisel and/ or by standard power driven percussion type or of approved make including tapering of all edges, making square shoulders of cavities including cleaning the exposed concrete surface and reinforcement with wire brushes etc. and disposal of debris for all lead and lifts all complete as per direction of Engineer-In-Charge50mm average thickness

26.29.1:Cleaning of reinforcement from rust from the reinforcing bars to give it a total rust free steel surface by using alkaline chemical rust remover of approved make with paint brush and removing loose particles after 24 hours of its application with wire brush and thoroughly washing with water and allowing it to dry, all complete as per direction of Engineer-In-Charge.Bars upto 12 mm diameter

5.22.6:Steel reinforcement for R.C.C work including straightening, cutting, bending, placing in position and binding all complete upto plinth levelThermo - Mechanically Treated bars of grade Fe-500D or more

OD23554/2025-2026:Applying two component (liquid polymer part and powder part) high build polymer modified cementitious reinstatement repair mortar, Rendroc HB2 / approved equivalent make preferable with a gloved hand or trowel using wet on wet technique to make sure that high strength polymer mix covers the reinforcing bar on all sides . Before applying Rendroc HB2 / approved equivalent make, the reinforcing steel should be primed and SBR should be tacky. For one bag of 18kg Rendroc HB2 / approved equivalent make, place about 2.75litres of drinking quality water in the mixer and add the supplied liquid polymer part, mix well in the mixer machine in operation, add Rendroc HB2 / approved equivalent make powder and mix for 2 to 3 minutes. Depending on the ambient temperature and the desired consistency, a small additional amount of water may be added up to a maximum total water content of 3.25 litres. Measurement is made for whole exposed area Including cost of materials, labour charges, conveyance of materials to site, hire charges of tools and mixer machine etc complete.

OD23555/2025-2026:Applying corrosion inhibitor one coat of nitozinc / approved equivalent make primer (two component system based on metallic zinc and epoxy resin and shall be mixed until a homogenous mixture is obtained) on the cleaned and dried reinforcing bar using a small paint brush such that the zinc rich primer coated should make an unbroken continuous film on the bars. ( If in doubt of having achieved an unbroken coating, a second application should be made as soon as the first coat is fully dry). After drying the treated surface, apply one coat of bonding agent Nitobond A R/SBR. Measurement is made for whole exposed area including cost of materials, labour charges, conveyance of materials to site, hire charges of tools etc complete.

OD23556/2025-2026:Providing and laying in position cement concrete of specified grade excluding the cost of centering and shuttering - All work up to plinth level: 1:2:4 (cement : 2 coarse sand : 4 graded stone aggregate 20 mm nominal size) Modified cement concrete with SBR at 2% by weight of cement

26.31.1:Providing, mixing and applying bonding coat of approved adhesive on chipped portion of RCC as per specifications and direction of Engineer-In-charge complete in all respect.SBR Polymer (@10% of cement weight) modified cementitious bond coat @2.2 kg cement per sqm of surface area mixed with specified proportion of approved polymer

26.31.2:Providing, mixing and applying bonding coat of approved adhesive on chipped portion of RCC as per specifications and direction of Engineer-In-charge complete in all respect.Epoxy bonding adhesive having coverage 2.20 sqm/kg of approved make

26.33.1:Providing, mixing and applying SBR polymer (of approved make @ minimum 2% by wt. of cement used) modified plain/reinforced cement concrete for structural members having minimum characteristic compressive strength [with ordinary portland cement, coarse sand and graded stone aggregate of 10mm maximum size in proportion as per design criteria] with specified average thickness. Note: Rates shall be for finished surface area of concrete and shall include the cost of labour, concrete and appropriate approved Super-Plasticiser for rendering concrete as flowable and SBR polymer but shall exclude cost of reinforcement, bond coat, Shear Keys, centering and shuttering, strutting, propping etc (Payment under this item shall be made only after proper wet curing has been done and surface has been satisfactorily evaluated by sounding/tapping with a blunt metal instrument)50mm thick in Grade M 25 with cement content not less than 330 kg per cum

2.25:Filling available excavated earth (excluding rock) in trenches, plinth, sides of foundation etc. in layers not exceeding 20 cm in depth, consolidating each deposited layer by ramming and watering, lead up to 50 m and lift up to 1.5 m.
