INSPECTION TEST PLAN

The inspection and test plan is a vital part of Quality control and Quality assurance plan. It occurs in different stages of work implementation as already shown in our Performance schedule. The test plan procedure is carried out in three stages of inspection and testing.

1. Surface preparation2. Coating applications3. Concrete Repair

1. Surface Preparation: On Steel Beam SurfacesDuring surface preparation, the one length section of steel beam is enclosed properly with management of proper air circulation system equipment such as PARP and Respiratory Protective devices. Steel has to be sand blasted according to SSPC-SP-10 (NACE Standard) or SA 2 ½ (ISO 8501-1). Average surface profile Rz > 50μm has to be achieved. Ensure that the substrate is free from containments detrimental to adhesion. The blasting is done by Euro grit, Aluminum Oxide, Copper slag 1 and 2.The surface is thoroughly inspected to remove any sharp edges, undercut, rough beads etc. After inspection, the survey of steel member will carry out to determine thickness with precise measurement such as calipers and the steel area loss is calculated in percentage at the Initial and after blasting. Furthermore, the procedure is carried out as specified in specification for strengthening. After strengthening, again the surface roughness, splatter of weld is inspected and removed if any. On Concrete SurfacesAll the Cracks underside of slab will be inspected thoroughly and marked the repair areas. The temporary propping will be done around the repair areas. The Loose concrete near the cracks will be removed and concrete will be removed at least 25mm behind the rusted reinforcement. The rusted bar is blast clean. The repair area will be enclosed properly with management of proper air circulation system equipment such as PARP and Respiratory Protective devices. Rusted Steel has to be sand blasted according to SSPC-SP-10 (NACE Standard) or SA 2 ½ (ISO 8501-1). Average surface profile Rz > 50μm has to be achieved. Ensure that the substrate is free from containments detrimental to adhesion. The blasting is done by Euro grit, Aluminum Oxide, Copper slag 1 and 2.The diameter of steel reinforcement will be measured and the steel area loss is calculated in percentage at the Initial and after blasting. Furthermore, the procedure is carried out as specified in specification for strengthening.

2. Coating applications:The Coating of Steel beam will be done by Sika Guard 62.The working areas shall be protected from strong winds or rain etc., to prevent adverse conditions for the materials preparation, application and curing during and after the lining works. The Climatic conditions such as Ambient and Surface temperature shall be defined as Substrate temp. > 3°K above dew point and measured e.g. by thermometer, hygrometer, dew point table. The range of temperature should be Min. +10°C (but at least 3°K above dew point) and

Max. +35°C. In all of the application condition, the substrate must be at least 3°K above dew point. The mixing and application of this coating along with the applicator’s information is attached in the Annexure of this submittal for reference.

3. Concrete repair:

After Completion of strengthening of reinforcement bars, the Coating of steel bar carry out by Sikaguard 62. The working areas shall be protected from strong winds or rain etc., to prevent adverse conditions for the materials preparation, application and curing during and after the lining works. The Climatic conditions such as Ambient and Surface temperature shall be defined as Substrate temp. > 3°K above dew point and measured e.g. by thermometer, hygrometer, dew point table. The range of temperature should be Min. +10°C (but at least 3°K above dew point) and Max. +35°C. In all of the application condition, the substrate must be at least 3°K above dew point. The mixing and application of this coating along with the applicator’s information is attached in the Annexure of this submittal for reference. After completion of Coatings, a dense concrete repair mortar, Sika MonoTop 615HB will be applied as mentioned in data sheets of Sika Monotop 615HB.

The Inspectors CV and inspection procedure check list of Steel beam lining is also attached in the Annexure-I of this submittal for reference.
