• Directed topographic and boundary surveys covering 2,900+ acres for industrial, residential, and commercial developments; provided accurate data for design, cut-fill calculations, and site planning.
• Managed comprehensive set-outs for 60 km of road construction, including control network establishment, layout verification, and on-site discrepancy resolution.
• Supervised layout and set-out activities for 50 MLD (Million Liters per Day) water treatment plant and nine common effluent treatment plants (CETPs), ensuring accuracy and timely execution.
• Checked layouts and prepared as-built drawings for 85 km of stormwater and sewer networks; coordinated installation of 120 km of recycled and potable water distribution lines across multiple sectors.
• Performed cable-trench and high-tension (HT) alignment surveys for substation construction; provided survey data supporting infrastructure development and resolved field coordination issues.
• Led 8,500-acre land survey with periodic ground level monitoring and soil quantity tracking for design and rehabilitation planning.
• Managed GFC (Ground Finished Cover) documentation and as-built preparation for multiple infrastructure components.
• Key Achievement: Delivered accurate survey data and layouts across township projects (Reliance MET City) with zero rework in quantity calculations.

• Supervised the construction and commissioning of four inlet pumping stations, enhancing storm water management under the AMRUT scheme.
• Managed the installation of eight rainwater harvesting units across city sectors, in compliance with water conservation standards.
• Prepared as-built drawings and calculated earthwork and storm drainage quantities for project closure and billing, facilitating accurate project documentation.
• Provided quantity verification and estimation support for drainage, water management, and infrastructure.

• Conducted detailed topographic surveys along canal alignments; monitored distribution lines, and village culvert installations.
• Managed aqueduct and culvert layouts while calculating earthwork quantities using cross-sections and Excel to facilitate infrastructure upgrades.
• Coordinated with design teams on longitudinal sections and design modifications, and ensured excavation conformed to design specifications through progress monitoring.
• Supported project coordination between the survey and execution teams.

• Ensured quality and compliance of road construction layers; verified ROB (Rail Over Bridge) and VUP (Vehicular Under Pass) alignments, and layouts.
• Reviewed and approved RFIs (Requests for Information) to uphold schedule alignment and quality standards, ensuring project continuity.
