Civil Engineering & Mining Technology in Bangalore

A wireless sensor network installed on a 1:20 scale bridge model, measuring strain, deflection and vibration under controlled loading. STM32-based nodes transmit data via LoRa to a gateway, and a Python dashboard visualises real-time structural response and flags anomalies against a FEM baseline model built in ANSYS.

A comparative material study evaluating crack-healing efficiency in concrete specimens incorporating three healing agents: encapsulated sodium silicate, Bacillus subtilis bacterial spores, and polyurethane microcapsules. Crack width, compressive strength recovery and water permeability are measured at 7, 14 and 28 days post-cracking.

A spatial analysis workflow in QGIS that integrates DEM data, land use classification, drainage network topology and historical rainfall records to produce a multi-tier flood hazard map for a selected urban catchment. Sensitivity analysis quantifies how a 20% increase in imperviousness changes the 100-year flood extent.

An experimental investigation into the effect of shredded LDPE plastic waste on the Marshall stability and flow properties of bituminous concrete mixes. Mix designs with 0%, 4%, 8% and 12% plastic content by weight of bitumen are prepared, compacted and tested, with results compared against VG-30 control mix benchmarks.

A site-specific water balance model for a 5,000m² commercial building rooftop catchment that optimises cistern sizing to maximise supply reliability across Bengaluru's bimodal monsoon pattern. The model outputs a demand-reliability curve and a 20-year NPV analysis comparing harvesting against municipal supply costs.

A full Building Information Model of a G+3 residential structure in Revit, linked to a quantity take-off schedule and a project timeline in MS Project to produce a 5D model that dynamically updates cost estimates when design parameters change. Clash detection reports and construction phasing animations are included in the deliverable.

An underground mine safety system using MQ-series gas sensors (CO, CH4, H2S) and particulate sensors mounted on a ruggedised ESP32 node, with a LoRa uplink to a surface control room. The system triggers zone-specific audio/visual alarms and sends SMS alerts when gas concentrations exceed DGMS threshold limits.

A laboratory investigation into the stabilisation of expansive black cotton soil using combinations of fly ash, GGBS and lime at varying percentages. CBR, UCS, Atterberg limits and swell pressure are measured for each combination, establishing the optimal blend for sub-grade stabilisation in Karnataka road construction.

A comparative finite element study in ETABS analysing the seismic performance of a G+10 RC frame building with three shear wall configurations (core wall, coupled wall, perimeter wall) under IS 1893 Zone III ground motion. Storey drift, base shear and ductility demand are compared across configurations.

An IoT-instrumented scale model of a water distribution network with pressure transducers and flow meters at six nodes, an ESP32 controller managing pump speed via VFD, and a SCADA interface that detects pipe burst events from pressure signature anomalies and isolates the affected zone within 3 seconds.

A mix design investigation into pervious concrete using single-sized 10mm and 20mm aggregates with water-cement ratios of 0.30–0.38, measuring permeability coefficient, compressive strength and void ratio for each combination. Results are mapped against ASTM C1701 targets for stormwater infiltration applications.

A video-based traffic survey system using a fixed camera and a YOLO v8 object detection model to automatically classify and count vehicles by type (2W, 3W, car, LCV, HCV, bus) at a selected intersection. PCU-weighted flow rates are computed and compared with manual classified counts to validate the automated method.
