Project Profile Summary
This industrial engineering project was successfully proposed and planned for the client Al Fanar Projects in Madina, Kingdom of Saudi Arabia (KSA).
The official techno-commercial proposal was finalized on December 29, 2024, under the Power Utilities and Grid Infrastructure sector.
The total field schedule and data processing window was completed within a strict timeline of 15 working days under favorable weather conditions.
Project Overview
We took on the assignment to map out a long and narrow strip of land for Al Fanar Projects in Madina, KSA.
The main objective of this assignment was to gather highly accurate ground elevation and asset data for a new 110 kV double-circuit overhead and underground power line.
The field mapping work covered a total survey distance of 44 kilometers long with a Right of Way width of 34 meters wide.
By surveying this massive pathway, the team provided the core layout maps that construction crews needed to build the electrical grid safely and without errors.
Tools and Field Devices Handled
To complete this work without relying on flying drones, the field team successfully handled a variety of high-precision ground measurement devices.
The team operated 4 high-precision satellite GPS and GNSS devices to communicate with global networks and calculate exact ground spots down to the centimeter.
For areas with crossing wires and tall towers, the crew utilized 1 high-precision Total Station to measure exact three-dimensional angles and physical distances.
The team also deployed 1 Ground Penetrating Radar (GPR) to safely scan and identify items located directly underneath the dirt surface.
All collected field data was checked right on the site using field laptops and tablets running specialized surveying software.
The entire operational crew, which consisted of 4 professional surveyors and 1 helper, was fully outfitted with standard safety kits including helmets, bright high-visibility vests, and heavy-duty safety boots while traveling across the route in 2 dedicated field cars.
Core Responsibilities and Technical Execution
The daily operations were divided into clear technical tasks to ensure complete accuracy along the transmission line.
The first phase involved setting up a secure ground control network in accessible zones to anchor all upcoming survey points.
The crew utilized official reference points provided by the Saudi Electricity Company (SEC) as the primary baseline for the route mapping.
Once the baseline was fixed, the team walked the route to capture ground elevation data points at strict 25×25 meter grid intervals.
During this walkthrough, the surveyors located and documented every natural and man-made obstacle within the Right of Way, including intersecting overhead lines, light poles, and telecom towers.
The final operational phase focused on building and measuring physical guideposts.
The team constructed 5 Permanent Reference Monuments (PRMs) spaced exactly every 10 kilometers along the route.
Each monument was made using a 3-inch PVC pipe filled with concrete, standing 60 centimeters high above the ground and buried 40 centimeters deep for long-term hold.
The team measured these permanent monuments using static satellite observation to ensure all mathematical errors were removed.
Additionally, the team installed 45 Survey Benchmarks (BMs) every 1 kilometer or at every major path turn along the route.
These benchmarks consisted of metal sticks set securely into the concrete or asphalt and were measured using fast Real-Time Kinematic (RTK) satellite observation referenced back to the nearest permanent monuments.
Engineering Deliverables
At the end of the 15-day timeline, all raw data points were fully processed and formatted into standard engineering files for the client’s design team.
The first set of files consisted of clean CSV text files which provided structured data tables showing exact point numbers and descriptions.
The second output included XYZ files which displayed the plain text geospatial point coordinates for every mapped area, clearly listing the longitude, latitude, and elevation values.
Finally, the crew converted the entire land map into 3D digital CAD blueprints which allowed the construction engineers to load the data straight into their building platforms.
