TS 1: SUPPORT SYSTEM: GENERAL: Renovation works does not mean replace of fitting fixture, plaster paint and forget. Contractors are advised to treat this part of tender/Contract with an understanding that is more serious than for new works. It is editable that the work when carried out by the contractor is done with full knowledge of the material used, its high points and its shortcomings. Every additive used should be properly dealt with and prior approval about the methodology of repair and mixing proportions be ascertained by the contractor from the consultants. Preparation for any work forms an important part of repairs and rehabilitation work and due importance be given to all surface preparation. Approval and consultants go ahead is required whenever such surface preparations are mandatory before actual repairs can start. Improper preparation can lead to future failures. All repairs to structural members must be preceded with a proper support system. This structural support system must be worked out for each structural member. Structural significance and safety of the whole building is of paramount importance. Necessary suitable propping is required to be provided shall have proper bottom and top bearing planks of proper material and area with adequate thickness (minimum 25mm). The props shall be tight and vertical and should not move or vibrate when tapped. A guideline to check if the number of props provided is sufficient being for wood. One wooded prop of 100 mm dia. shall carry 3 T of load. Unless detailed calculations are done, the following approximate shall apply. Every column carries approximately the following load: Wc = Wcon + Wst. Where Wcon = Y where Y is the breadth in cms if width is 23cms And Wst is as follows:
Dia in mm
load per bar
12 2 T 16 4 T 20 6 T 25 9 T
So Wst = load per bar x No. of bars It is mandatory to support every column being jacketed.
TS 2 : REMOVAL OF CONCRETE/ PLASTER COVER:
2.1. The range of removal of plaster/ concrete cover shall extend to the limit of crack /hollowness /corrosion of rebar. The governing dimensions of removal shall be based on the minimum dimensions and/or shall extend beyond the zone of rusting to a minimum dimensions.
Page 79 of 127
2.2. Concrete surfaces to which treatment are to be applied shall be freshly exposed parent concrete free of loose and unsound materials. Prepare surfaces by mechanical abrasion unless prohibited by environmental limitations in which case acid etching may be used. 2.3. A good base or foundation shall be prepared for successful application of any treatment. 2.4. All unsound /weak concrete/ mortar material shall be first removed by the contractor up to the required depth. Chipping shall continue until there are no offsets in the cavity, which will cause an abrupt change in the thickness of repaired surface. No square shoulders shall be left at the perimeter of the cavity, all edges shall be tapered. The final cut surface shall be critically examined to make sure that it is sound and properly shaped. 2.5. All treated area shall always measure after chipping is complete. It shall be measured as the nearest geometrical shape. Thickness measurements for structural repair shall be taken as average thickness measurement backward from theoretical calculations based on chemical consumption’s. Such cases of average thickness exceeding 25 mm shall be paid on prorate basis of quoted rate. TS 3: CLEANING OF SURFACE: 3.0. Cleaning of concrete surfaces. 3.1. Concrete surface to which treatment are to be applied shall be freshly exposed parent concrete free of loose and unsound materials. Prepare surfaces by mechanical abrasion unless prohibited by environmental limitations in which case acid etching may be used. 3.2. Mechanical abrasion:- Use sandblasting or scarifying or wire brushing or other approved means. The purpose of this is to achieve a surface that is clean and dust free. Distressed loose concrete is to be removed. 3.3. Acid etching:- Etch surface with a commercial grade of hydrochloric acid diluted at a ratio of 10:90 to 20:80. After this application, scrub surface with a stiff bristled broom, brush, or similar implement. Immediately after foaming action of acid has subsided, flush surface with water jets until all residues is removed. Repeat procedure until Latinate is completely removed. Wash such areas with water at least three times and allow to air dry prior to further treatment.
TS 4: WATER CLEANING. 4.1. All surfaces so prepared as per TS 2 and TS 3, have to be cleaned of all the effects of the above procedure. 4.1.1. A fresh water jet is recommended for the cleaning process. This is aimed to remove all dust, oil, rust particles and any such deleterious material that is not conducive to sound construction practices. The jet pressure can also be achieved by a stream of fast flowing water from a pipe. 4.2. Inspection of concrete surfaces prior to mortar application.
Page 80 of 127
4.2.1. Inspect all concrete surfaces prior to application of mortar to ensure that section is free from loose particles and deleterious materials , cracks and effects of corrosion or carbonation . 4.2.2. Surfaces shall be free of any deleterious materials such as Latinate, curing compounds, dust, dirt, and oil. Materials resulting from surface preparation specified in Article 3.1 shall be removed. 4.2.3.1. All concrete surfaces shall be dry as defined in Article 4.2.3.2 below unless a water-insensitive coating is used. 4.2.3.2. Evaluate moisture content for concrete by determining if moisture will collect at boundary lines between old concrete and new coating before the new coat has cured. This may be accomplished by taping a 4 x 4 ft polyethylene sheet to concrete surface. If moisture collects on underside of polyethylene sheet before polymer would cure, then allow concrete to dry sufficiently to prevent the possibility of moisture between old concrete and new layer. TS 5: CHIPPING OF CONCRETE COVER: 5.1. The range of removal of concrete cover shall extend to the limit of crack /hollowness /corrosion of rebar. The governing dimensions of removal shall be based on the minimum dimensions given in the drawing and/or shall extend beyond the zone of rusting to a minimum dimension as specified in the drawing. 5.2. Concrete surfaces to which treatment are to be applied shall be freshly exposed parent concrete free of loose and unsound materials. Prepare surfaces by mechanical abrasion unless prohibited by environmental limitations in which case acid etching may be used. 5.3. A good base or foundation shall be prepared for successful application of any treatment. 5.4. All unsound /weak concrete/ mortar material shall be first removed by the contractor up to the required depth as directed by engineer. Chipping shall continue until there are no offsets in the cavity , which will cause an abrupt change in the thickness of repaired surface. No square shoulders shall be left at the perimeter of the cavity, all edges shall be tapered. The final cut surface shall be critically examined to make sure that it is sound and properly shaped. 5.5 All areas so chipped shall be subjected to water cleaning and drying. No deleterious material shall be left on the chipped surfaces. It is essential that the loose and cracked concrete shall be properly removed. It is essential that concrete around the rebar, which shows corrosion shall be removed properly, and sufficiently to ensure proper cleaning of rust from the rebar. 5.6 Incase the distressed concrete extends into the core of the section it is essential to seek the consultant's approval prior to removal of this concrete. It is essential also to design proper support system and prop the area prior to removal of concrete beyond 5 mm inside the core area.
Page 81 of 127
TS 6 BOND COAT: 6.1 The specific quality requirements as stipulated in STS 6 above for a common work of bonding needs in restoration shall be followed. All the test facilities are generally not available even in sophisticated labouratories in the country. Few manufactures do have such an in-house facility with them. The difficulty therefore lies in strict stipulations and their subsequent job-site compliance. Therefore, reliability of the product quality is important. The coat of approved material shall be applied to all exposed surfaces of concrete at least 20 minutes prior to polymer modified mortar / treatment. The material to be used shall be nonacidic in nature. List of approved material is given elsewhere in the document. Only those materials shall be allowed to be used. All chemicals used for Rust Inhibition, Bond coat, Polymer Modified Mortar shall be of same generic and same manufacturer. 6.2. The items to be used shall comply with all requirements as specified in STS 6 and the material purchased shall be given in the consultant's custody in the original manufacturer’s sealed manner. It shall always remain in the consultant’s custody. 6.3. Execution 6.3.1 Preparation of concrete surface 6.3.1.1.

Page 93 of 127
11.8.2.2. ISOTHANE EMB is a membrane coating, not paint and as such protection is only achieved with high film build, i.e. 1m m minimum. It is therefore essential that this is achieved. The membrane can be applied on one 1m m or two 0.5 mm coats. Two coats recommended on uneven and joined surfaces to minimize the possibility of thin patches, missed areas and pin holing. In the case of two-coat application, it is important to recoat within 24 hours of the first coat becoming sufficiently cured to allow operator access. 11.8.2.3. Do not dilute ISOTHANE EMB Methodology of application should be as follows: 11.8.2.3.1. Remove all loose material by vigorous brushing, wire brush if necessary. 11.8.2.3.2. Treat any remaining fungal growth with proprietary fungicide as recommended. 11.8.2.3.3 Allow surface to dry thoroughly and any moisture contained in the structure to evaporate. ISOTHANE Special primer and EMB should not be applied to damp substrates. 11.8.2.3.4 Fill cracks and voids with a mastic sealant. 11.8.2.3.5. Prime with ISOTHANE Special primer ( 6-10 sqmtrs /It) depending on substrate texture and porosity) which cures to a slightly tacky film in 2-4 hours. Overcoat with ISOTHANE EMB as soon as possible after this time and certainly within 48 hours. If delay exceeds this, re-priming is advised. 11.8.2.3.6. Apply ISOTHANE EMB at a maximum film thickness of 0.5 mm for two- coat applications and 1 mm for one coat. 11.8.2.3.7. In the case of two coat application, the first coat should be touch dry in 12-48 hours (in some conditions this might be delayed) the second coat should be applied within 24 hours of this stage to ensure good adhesion. 11.8.2.3.8. Second coat delay :-If more than 24 hours elapse after the touch dry stage of the first coat, prime the entire surface with Special Primer and allow drying before re-coating within 4-8 hours. 11.8.3.9. Day-work joints-where application extends over more than a working day, an overlap of 150mm should be used. 11.8.3.10. Aromatic hydrocarbon solvent should be used to clean equipment etc. 11.8.3.11. Spray Application: Only airless spray should be used. Graco King 60 to1 ratio or similar. Compressor: - 100 psi 60 cfm min. Tip Size: - 28/30 thou. 60 Angle.

TS: 19A CPVC PIPES : The material used in the manufacture of the pipe shall be a rigid chlorinated polyvinyl chloride (CPVC) compound, type IV grade I, with a cell classification of 23447 as defined in ASTM D1784 ( American society for testing and materials). The compound shall be light grey in colour, and shall be approved by NSF (National Sanitation Foundation) for use with potable water. CPVC schedule 40 and Schedule 80 pipe shall be manufactured in accordance to the requirements of ASTM F441 for physical dimensions and tolerances. Each production run of pipe manufactured in compliance to this standard, shall also meet the test requirements for materials, workmanship, burst pressure, flattening, and extrusion quality defined in ASMT F441. All belled-end pipes shall have tapered sockets to create an interferences-type fit, which meet or exceed the dimensional requirements, and the minimum socket length for pressure-type sockets, as defined in ASTM D2672. CPVC offers greater heat resistance, withstanding corrosive water temperatures between 70 degree F and 90 degree F higher than PVC. CPVC is non- toxic, and offers greater strength and flexibility. CPVC pipe is immune to galvanic corrosion and resist scale build up. It is also resistant to chemicals, and durable against their residues,. Being plastic, it is not subject to electrolysis, the process in which water breaks down into oxygen and hydrogen gas. Installation is safer and faster, requiring only special solvent cement, as opposed to a torch and solder for metal piping. CPVC piping generally lasts longer, as it is less susceptible to failures. CPVC piping is recognized in all model-plumbing codes. For hot and cold-water applications, it is typically rated at 100 psi at 180 degree F and 400 psi at room temperature. CPVC is fire resistant and will not burn without a flame source, making it suitable for fire suppression systems in light hazard and residential settings. WORKMANSHIP: A: Installation of CPVC pipe
1. Sand the ends of both pipes you are connecting. You do not need to sand the inside of the pipe, only the outside ring that will fit into the coupler. The coupler you choose should be the proper size for the pipes you are connecting. Sand the pipe until you have removed its shiny appearance.
2. Apply PVC cement to the sanded ends of your pipes and the insides of the coupler.
3. 3. Slowly twist the coupler on to the end of the pipe that is connecting to. Once PVC cement is applied you have roughly two minutes of working time until it begins to cure.
4. Twist your new pipe into the other end of the coupler to finish the installation.
Page 101 of 127
B: Glue to CPVC pipe 1. Lay out the CPVC pipes to be fitted together. Push the pipes together in the
couplings to make sure they fit, and check the pipes for burrs, which must be removed with light sandpaper before gluing together.
2. Cover the end to be glued with CPVC primer, available at any hardware store. Primers will come in cans and have their own applicator brush built into the cover. At the same time, coat the inside of the coupling joint with CPVC primer, where the end is to be inserted.
3. Cover both the end and the inside coupling to be joined with CPVC glue. Be liberal with the glue application, and make sure there are no dry spots. The glue is found at hardware stores, and will have its own applicator built into the cover.
4. Push the end of the pipe into the coupling immediately after the glue has been applied, then slightly twists the pipe to ensure that all sides of the pipe inside the coupling Make a solid and firm connection. Repeat this process with as many pipes and coupling that you have.
C: Connection Of CPVC to CPVC pipe
1. Cut the pipe to the proper length and remove any burrs or rough edges on the cut surface.
2. Test-fit the pipe and fitting. Make sure all pieces fit together firmly before applying adhesive.
3. Coat the fitting and pipe with CPVC pipe cement and fit together. Use only cements formulated for CPVC pipe. Follow the manufacturer’s instructions concerning curing times.
CONNECTING CPVC TO COPPER: 4. Cut the pipe to the proper length and remove any burrs or rough edges on the
cut surface. 5. Attach a transitional fitting to the CPVC pipe according to the manufacturer’s
instructions. These unions are available at most home building supply outlets and plumbing supply stores. The fitting is usually glued into the CPVC pipe and uses a compression fitting on the copper pipe.

In case of any loose, soft or bad ground being met with it shall be excavated to a solid foundation and filled up to the level of the sewer with concrete or as may be otherwise directed by the Engineer. 21.2. In the floor of every sewer trench not specified or ordered to be concreted, as joint hole shall be formed for receiving not only the socket of the pipes, but the mass of clay to be placed all round every joint of the sewer not concreted. In all cases, except where otherwise specifically ordered, the trenches for the sewers under twelve feet shall be opened out. 21.3. In excavating any trench, the materials forming the surface of any road, foot-path, garden or field, shall be kept separate and preserved for re-use at the surface when the trench is filled up. Before any road-metal is re-used it shall be carefully shifted. 21.4. After the foundations of any building or other works have been constructed, or the sewer or drain and other pipe have been laid and jointed or the sewer constructed and the manholes and ventilators are made and as soon as the joints have inspected and passed by the Engineer or his Assistants, the trenches shall be re-filled with the materials taken therefrom. In re-filling the trenches, the utmost care shall be exercised so as not to disturbs break or damage then jointed pipes, and immediately over and around every pipe the finest selected material shall be put. No lumps of rock, earth or other material shall be put round the pipe or be thrown into the trenches until the same has been protected by the fine material before referred to. The ground, as it is being filled into the trenches, shall be rammed until it is completely consolidated and water should be used in addition, if considered necessary by then Engineer, to aid in the consolidation of the trenches. Very great care shall be exercised so that trenches are filled in solidly under the pipes with selected material and that no damage is done to the pipe during then process of consolidation. 21.5. When the contractor is directed to supply pipes they shall be of the following description. The pipe used in the works shall be the best and of approved quality. All pipes shall be perfectly airtight and truly cylindrical, glazed inside and outside, free from cracks and flaws, and perfectly burnt.

21.6. All pipes in trenches over 4.5 meters deep and all those in loose ground shall be protected with concrete all round. 21.7. In laying the drains care must be taken that they are laid perfectly true to the inclination, and as far possible, straight from point to point of the manholes, ventilators or lamp holes, and that all pipes are carefully laid and packed underneath so as to guard against subsidence or fracture of the pipes. 21.8. The stoneware pipe shall be joined by forcing two stands of tarred gaskets into the joints, the strands to be sufficiently thick to tightly fit the annular space between the sockets and spigots. The annular space shall then be solidly filled with neat Portland cement which shall be forced into the socket, so s to fill it and fillet of cement shall then be worked round the outside of the joint. This fillet shall be kept in position by a bend of coarse cloth, which shall be kept moist until the cement has set. Every joint of the earthenware pipes, which is not concreted shall be further protected by placing, on the outside of the joint of cement, well-tempered and tenacious clay, so as to completely surround the joint. For this purpose, not less than the following quantities of clay shall be used for every joint on a (6 inch) 152.397 mm. pipe, 1/2 cubic feet 14158.0 c.c; 8 inch 203.196 mm. pipe, (3/4" cubic feet) 21237.00 c.c. 9 inch 228.586 mm. pipe, 1 cubic feet 28317 c.c.: (10 inch) 253.995 mm. pipe, (1 1/4 cubic feet) 35400.0 c.c. 21.9.
