Executive
Overview
In one of Riyadh’s most challenging urban environments, AFAQ delivered a high-precision topographic survey across 20+ sites in under three months. With high-rise structures blocking GNSS signals and a compressed schedule, we deployed total station and 3D laser scanning as primary methods, established a local control network, and fused multi-source data into design-ready terrain models — delivered on time, with zero delays to the design phase.

The Engineering
Challenge
Dense high-rise development blocked GNSS satellite signals across the district, ruling out conventional GPS-only survey methods.
A compressed schedule required more than 20 sites to be surveyed and delivered without delaying the design phase.
04
The AFAQ Solution
Local Control Network
Established a local geodetic control network to overcome GNSS signal obstruction between the towers.
Survey & Data Collection
Deployed total station (1″) and 3D laser scanning as primary methods across all 20+ sites.
Data Fusion & Modelling
Fused multi-source measurements into design-ready terrain models in AutoCAD Civil 3D and GIS.
On-Time Delivery
Handed over on schedule with zero delays to the client's design phase.
05
