ABSTRACT
This project aims to carry out a route alignment survey of Benin technical college road. Accessibility is a constant worry in a city like Benin that is growing quickly. Road infrastructure is a critical component of urban development, facilitating connectivity and economic activities. However, the residents of Benin technical college road in Egor Local Government Area of Edo State have faced challenges due to inadequate access to the road. The methodology adopted for this project employed the High-Target GNSS Equipment for precise data acquisition along the road segment at regular 25-meter intervals. The GNSS receiver facilitated the collection of X, Y, and Z coordinates, essential for creating a detailed geospatial dataset. Subsequently, AutoCAD Civil 3D software was utilized for processing the acquired data and generating geometric designs. Civil 3D enabled the creation of horizontal and vertical alignment profiles, cross-sections, and volume calculations, ensuring compliance with design standards and regulatory requirements. The result of this project is a well-detailed geometric design of the road which includes the horizontal and vertical alignment profiles, cross-section designs, and volume calculations for cut and fill. The total cut volume was determined to be 10,101.46 m3 , with a fill volume of 559.96 m3 . Additionally, the total cut area and fill area were measured at 207.974m2 and 17.100m2 respectively. Cross-sections of the road at every 25-meter interval were generated using AutoCAD Civil 3D which shows the elevation of the road segment. In conclusion, The GNSS receiver is recommended for a proper road with better accuracy.
