Visual Survey: Visual inspection for surface damages, damage classification. The visual inspection shall largely cover areas of high distress, corrosion, moisture, leakage, abnormal variations in structure, algae and fungus growth, efflorescence, etc. Visual inspection would be documented in the form of worksheets, photographic records, and distress over drawings. Simple tools and instruments like camera with flash light, magnifying glass, binoculars, chisel and hammer, etc shall be used for measuring the distresses as per site requirement. Inclusive GST and Other Incidental Charges.

Rebound Hammer Test: Uniformity of concrete in terms of surface hardness as per IS 13311 (Part-2)-1992, ASTM C 805-02, BS 6089:1981 and BS 1881: Part 202, BS-EN:13791 with plotting of histogram as well as normal distribution graph. Inclusive GST and Other Incidental Charges.

Ultrasonic Pulse Velocity Test: for ascertaining the quality of concrete, uniformity of concrete in terms of soundness and density of concrete as per IS 13311 (Part-1)-1992, ASTM: C597-83, BS 6089: 1981 and BS 1881: Part 203 and BS-EN:13791. Inclusive GST and Other Incidental Charges.

Core Extraction and Testing: Extracting the concrete core samples following the codal provisions; and evaluating the properties (fck value, grade of concrete) in the laboratory from the core samples selected. IS 456:2000; IS 516:1959, IS 1199:2002; ASTM C-42, without encountering any steel reinforcement from the RCC members covered under the study at specified locations by site in-charge with portable power driven core cutting equipment. Inclusive GST and Other Incidental Charges.

Cover Depth Contour Mapping by Rebar Locator: Conducting a cover meter test at selected locations on RCC members of the structures covered under the study to see the adequacy of concrete cover to rebar as per the relevant design code of the particular structure. An average reading of the cover meter in a 150 x 150 mm grid line will be considered a single point at one test location. Note:- Interpretation for structural elements follows the code IS 456 for the building, IRC 112 for the bridges, IS 3370 Part 1, and IS 4651 Part 4 2019 for jetty structure or is specified in the GFC drawing (provided by the client). limitation of machine scanning penetration up to 80 mm depth. Inclusive GST and Other Incidental Charges.

Carbonation or alkalinity test with cover test: Measurement of carbonation depth or alkalinity of concrete by phenolphthalein spray test at selected locations (drilled powder sample or concrete core sample as per site condition) on RCC members of the structures covered under the study to see the depth of carbonation as per IS 516 Part 5 section 3 2021, BS EN 14630:2006, and BS EN 13295:2004. Cover depth is also measured at the same location to know the ratio of carbonation depth to cover depth to check whether the structure is in an incubation period or a deterioration period or to know the alkalinity of the concrete. Inclusive GST and Other Incidental Charges.

Half Cell Potential Test : Measuring the half-cell / surface potentials at selected locations on RCC members of the structures covered under the study to understand the extent of reinforcement corrosion in terms of probable risk of corrosion of steel bar as per ASTM C876. Note: The rate shall include surface preparation, moistening concrete surface. Inclusive GST and Other Incidental Charges.

Report Submission with root cause analysis, interpretation, conclusion, and recommendation: Preparing and submitting a comprehensive report consisting of findings from visual inspection, test data, interpretation of results, conclusions, and final recommendations along with a sketch indicating the location of the test. Note 1:- The recommendation part does not include the repair scheme/DPR or BOQ related to the project. Note 2:- Editable format of report The HD-quality site photographs and Video shall be provided to employer in a good quality of CD/DVD/USB hard disk along with a soft copy, but any data generated from the patented software can not be edited so those files can not be provided in the editable format like graphs, design output, backend algorithms, etc. Inclusive GST and Other Incidental Charges.

Repairing methodology and retrofitting scheme for structural serviceability—Thestructuralrepairandrehabilitationofthe structures shall have detailed technical specifications, materials tobeused,executionapproachdetails,vulnerabilityindices,and order of urgency to repair.
