Topographic Surveys in Saudi Arabia

A topographic survey is the starting point of every design and construction project. Our field crews measure ground levels, natural and man-made features, boundaries and utilities to produce accurate base maps that engineers and designers can rely on.

We use GNSS RTK receivers, robotic total stations and drones, tied to the national geodetic reference system, and every dataset is checked by a qualified engineer before delivery. We carry out topographic surveys for sites of every size, from individual plots to large developments, roads and infrastructure corridors across the Kingdom.

Scope

Plots, master plans, roads, utilities corridors, industrial sites and large developments.

Equipment

GNSS RTK receivers, robotic total stations, digital levels and drones.

Deliverables

DWG and PDF drawings, contour maps, DTM, cross sections and coordinate lists.

What we deliver

  • Detailed topographic and feature surveys
  • Contour maps and digital terrain models (DTM)
  • Longitudinal and cross sections
  • Cut and fill volume calculations
  • GNSS control points and benchmarks
  • Boundary and utility surveys

Typical projects

  • Residential and commercial developments
  • Roads, highways and infrastructure
  • Industrial and logistics facilities
  • Master planning and land subdivision
  • Government and municipal projects

Frequently asked questions

What coordinate system do you use?

Surveys are tied to the Saudi national geodetic reference (KSA-GRF17) and the projection required by the client or the municipality, such as UTM.

How large an area can you survey?

From a single plot to several square kilometres. For large areas we combine GNSS ground control with drone photogrammetry to deliver faster without compromising accuracy.

What do you need to prepare a quotation?

The site location or a KML file, the approximate area, the purpose of the survey and the required deliverables.

3D Laser Scanning and Scan to BIM in Saudi Arabia

We use the Leica RTC360 terrestrial laser scanner to capture complete, measured 3D records of buildings, facilities and infrastructure. Each scan collects millions of points in minutes, giving designers, contractors and owners a reliable digital copy of existing conditions.

From the registered point cloud we produce accurate 2D plans, sections and elevations, 3D models and BIM models in Revit, ready for renovation, expansion, fit-out, clash detection and asset documentation projects anywhere in the Kingdom.

Scope

Buildings, facades, MEP and plant rooms, heritage sites, industrial facilities and infrastructure.

Equipment

Leica RTC360 laser scanner with GNSS and total station control for accurate georeferencing.

Deliverables

Registered point clouds (E57, RCP), CAD drawings, 3D models and Revit BIM models.

What we deliver

  • As-built surveys of existing buildings and facilities
  • Scan to BIM: Revit models at the required level of detail
  • Plans, sections and elevations from point clouds
  • Facade, heritage and structural documentation
  • Clearance, deformation and flatness analysis
  • Volume and quantity calculations

Who we work with

  • Architects and design consultants
  • Main contractors and MEP contractors
  • Developers and facility managers
  • Government entities and heritage authorities
  • Industrial and plant owners

Frequently asked questions

How accurate is 3D laser scanning?

The Leica RTC360 measures points with millimetre-level precision. With survey control, the registered point cloud is typically accurate to a few millimetres across a building, depending on site conditions and scan density.

Which file formats do you deliver?

Point clouds in E57 and RCP, drawings in DWG and PDF, and BIM models in Revit (RVT). Other formats can be agreed at the quotation stage.

How long does a building scan take?

Field work for a typical building takes one to a few days. Processing and modelling time depends on the size of the building and the required level of detail.

Construction Survey & Engineering Support

From the first excavation to hand-over, construction projects depend on accurate setting out. We establish site control networks, stake out buildings, roads and utilities from the design drawings, and verify the work as it progresses.

Our engineers support contractors and consultants with monitoring surveys, quantity and volume calculations and as-built documentation, working to the project’s schedule and coordinate system.

Scope

Setting out, control networks, progress and monitoring surveys, as-built surveys.

Equipment

Total stations, GNSS/RTK receivers and digital levels with regular calibration.

Deliverables

Setting-out reports, control point schedules, as-built drawings and volume reports.

What we deliver

  • Site control network establishment
  • Setting out of foundations, columns, roads and utilities
  • Level control and monitoring during construction
  • Earthwork and stockpile volume calculations
  • As-built surveys and drawings for hand-over

Aerial Survey & Drone Mapping

Drone surveys capture large or hard-to-reach areas in a fraction of the time of ground methods. Using photogrammetry with ground control points, we produce georeferenced orthophotos, elevation models and 3D models of the site.

Aerial data is ideal for planning studies, earthwork estimates, periodic progress monitoring of construction sites and documentation of existing conditions.

Scope

Large plots, development sites, roads and infrastructure corridors.

Method

UAV photogrammetry controlled by GNSS ground control points for survey-grade accuracy.

Cadastral Surveys & Survey Reports

The survey report (Qarar Masahi) is the official document that confirms a plot’s location, boundaries, dimensions and area according to the approved plan and the title deed. It is required for building permits, deed updates, splitting or merging plots and many real-estate transactions.

We carry out the field survey, verify the plot against the approved planning documents, resolve any discrepancies in dimensions or area, and prepare and submit the survey report through the municipality’s Balady platform, following it up until it is issued.

Scope

Boundary verification, plot area and dimension checks, survey reports for permits and deeds.

Equipment

GNSS/RTK receivers tied to the national reference system and calibrated total stations.

Deliverables

Approved survey report, coordinate list, plot drawing and boundary marking on site.

What we deliver

  • Survey report (Qarar Masahi) for building permits
  • Boundary re-establishment and marking of corner points
  • Area and dimension verification against the deed and approved plan
  • Plot splitting, merging and re-planning drawings
  • Coordination with the municipality until approval
