LIFE CYCLE ASSESSMENT OF VARIOUS BUILDING AT NAVAL STATION KARANJA

Amount

Visual inspection of all visible structural parts (Column, beam, slab), external facades of the building, ancillary structures like Pump house, water tank etc. record our observations for structural distresses in the structural components like deflections in RCC/ Steel/ Timber members like column, beams, slabs, cracks in the structural members & also for items of maintenance like leakages/seepages, terrace water proofing etc. & suggest remedial measures to be taken for improving the durability of the structure as a whole to enhance its future life.

Ultrasonic Pulse Velocity Test: For ascertaining the quality of soundness of concrete as well as uniformity of concrete in terms of density, crack depth and width causal analysis of crack propagation as per IS 516 - Part 5 (Section 1) - 2018.

Rebound Hammer Test For determining the estimated compressive strength of concrete and uniformity of concrete in terms of surface hardness as per IS 516 - Part 5 (Section 4) - 2020

Rebar Scanning/ Profile Mapping of RCC Member by using Ferro Scanner for detecting Reinforcement. Location, Numbers/ Spacing of Rebars in RCC structural member of existing structure. (Accuracy subject to site condition).

Measuring the Half Cell Potential readings with wheel electrode at the nodes of pre-marked grip points on concrete surface in a suitable grip for determining the probability of corrosion activity of embedded steel reinforcement in concrete with specified half cell electrode in accordance with IS 516 - Part 5 (Section 2) - 2021.

Chemical analysis test for determination its chemical composition for chloride %, sulphate % & other parameters.

Estimation & Costing of Suggested Retrofitting Work. Includes Tentative measurement of Proposed Repair Portion of Structure, Prepare Methodology (Short Specification) of Suggested Repair Works, Provide BOQ as Per Government DSR Rates (Without Rate Analysis).

Preparation of Structural Audit Report which includes: A) The findings from detailed Visual Inspection in the form of Observations, Photographic Records and Critical Areas B) Non destructive test results & there interpretation to assess current state of condition & levels of deterioration C) Suggested economical viable remedial measures to restore structural stability and increase durability/residual life of building etc. Note:- 1. Based on result after conducting of above tests, Bill of Quantity (BOQ) shall be provided for cost analysis of strengthing of structure to make it suitable for serviceability of the bldgs. Maximum height of bldg is G+3.
