Conducting core extraction and testing. , Conducting 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.

Conducting half cell potential test. , Conducting 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. The rate shall include surface preparation, moistening concrete surface.

Conducting carbonation test. , Conducting carbonation test. Measurement of carbonation depth 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 carbonatoin as per BS EN 14630 2006, BS EN 13295 2004. Cover depth is also measured at the same location to know the ratio of carbonation depth.

Conducting pH value to check alkanity for concrete , Conducting pH value (to check alkanity for concrete) as per relavant BS 5328, ACI 201.2R-92 ACI-318-99, IS 456 2000, BS 8110

Preparing and submitting comprehensive report consisting of findings from visual inspection, test data, interpretation of results, conclusions and final recommendations. , Preparing and submitting comprehensive report consisting of findings from visual inspection, test data, interpretation of results, conclusions and final recommendations along with sketch indicating the location of the test. Recommendation part does not include the repair scheme/ DPR or BOQ related to the project. Evaluation and presentation on recommendations/ suggestions for approval measures of UNESCO/ ICM/EAG final submission. The HD quality site photographs and video shall be provided in a good quality of CD/DVD/USB hard disk along with soft copy but any data generated from the patented software cant be edited so those files cant be provided in the editable format.

Preparing methodology and retrofitting scheme for structural serviceability and safety , Preparing methodology and retrofitting scheme for structural serviceability and safety, periodic maintenance scheme, futuristic protection of structure. The recommendation for structural repair and rehabilitation to the structures shall have detailed technical specification, materials to be used and design details, vulnarbility indices and order of urgency to repair. Suggesting retrofitting methodology to increase the load carrying capacity of structural members, if members get failed in its required target load carrying capacity that will be also be the part of the given scope of work incl preparation/ retrofitting works (feasible and economic options) with rate analysis, material specifications, execution drawing for strengthening of structure alongwith technical specifications and periodic inspection and maintenance.
