Preliminary Route Analysis
Remote sensing and aerial imagery used to identify optimal highway corridors, avoid sensitive terrain, and assess land use.
HIGHWAY SURVEYS
Highway Surveys Solutions
Leading Africa's Land and Aerial Surveying Revolution. Highway surveys play a critical role in the planning, design, construction, and operation of road infrastructure.
Critical Infrastructure
Overview
Leveraging a mix of aerial imaging, UAV photogrammetry, LiDAR, GNSS, and conventional surveying, engineers can make data-driven decisions that ensure safety, efficiency, and sustainability throughout the lifecycle of a highway project.
What we offer
Highway Surveying Services
Topographic Mapping
Drone-based LiDAR and photogrammetry capture high-resolution elevation models for design-grade mapping and cut-fill analysis.
Ground Control Surveys
Establishment of ground control points (GCPs) using GNSS RTK for geo-referencing aerial data and validating spatial accuracy.
Alignment & Corridor Surveys
Detailed corridor surveying using total stations, GNSS, and mobile mapping systems to define centerlines, ROW, and cross-sections.
Safety
Accurate surveys contribute to road safety by ensuring proper alignment, clear sight distances, and appropriate signage.
Construction Monitoring
Integrated UAV flyovers and terrestrial control check progress, ensure compliance, and detect deviations in real time.
As-Built & Digital Twins
Post-construction 3D mapping using UAV and scanning tech feeds into BIM and digital twin environments for lifecycle asset management.
Value Drivers
Benefits of Integrated Highway Surveys
Planning & Design
Surveys provide essential data for designing new roads, considering factors like traffic volume, safety, and environmental impact.
Maintenance
Surveys help identify areas in need of repair, prioritize maintenance, and evaluate the effectiveness of repairs.
Utility Protection
Identifying and mapping utilities helps avoid damaging them during construction, minimizing disruptions.
Construction
Construction layout surveys ensure roads are built according to design plans and safety standards.
Safety
Accurate surveys contribute to road safety by ensuring proper alignment, clear sight distances, and appropriate signage.
Assets Management
Inventory surveys provide data for managing and maintaining highway infrastructure.
