ROUTE SURVEY

This project report presents the findings of a route survey conducted for the Evbhuku community road in Oredo Local Government Area, Edo State, Nigeria. The survey employed Differential Global Positioning System (DGPS) technology. The primary goal was to collect accurate topographic and cadastral data required for designing a new road and determining the necessary Right-of-Way. Fieldwork was carried out using two Hi-Target V300 GNSS receivers operating in Real-Time Kinematic (RTK) mode. This setup was used to map a 2-kilometer proposed corridor connecting Obe, Evbhuku, and Amagba communities. Data collected included the road's centerline, ground elevations at 25-meter intervals, and the locations of all existing features and property encroachments. The collected data was processed using Autodesk Civil 3D software. This involved converting coordinates to the local map grid and creating a detailed digital model of the terrain. From this model, engineering drawings were produced, including road plans, elevation profiles, and cross-sections. The survey also calculated earthwork volumes, identifying a net requirement to excavate approximately 13,115 cubic meters of material. The results confirm the survey achieved the necessary accuracy for road design. A major finding was the identification of significant land encroachment by buildings and a market along the first 350 meters of the route, which must be resolved before construction can begin. This project provides the essential mapped foundation for the subsequent stages of the road's development.
