⭐️⭐️⭐️⭐️⭐️ Architdata Ltd recently completed a measured and topographic survey for one of my projects. As an architect, they delivered everything I needed with exceptional professionalism. The survey was detailed, neatly presented, and turned around impressively quickly. The value for money was excellent, and the homeowner was also very impressed with how tidy and pleasant the surveyors were throughout. A fantastic service — highly recommended!

As an architect I have commissioned a number of measured surveys from Archidata over the years and they have always provided an excellent service.

Archidata were great to work with on topographical surveys we needed for an extension at a small care home. Service was great, friendly, pro-active and responsive and great output for our architects to work with.

Archidata were very professional and all went very smoothly. Great communication and no trouble at all. The sophisticated equipment they use meant the survey could be done very quickly and with no inconvenience to us.

Archidata did a full topographic survey of our (very complicated) split-level house and plot, which was the starting point for our renovation. More recently, they used the same data to try and help us with the garden design, producing sections through the plot to demonstrate the different levels. I would definitely recommend Rob and his team.
<p>Founded and managed by our director Rob Mclean, we work closely with clients all over the UK and beyond to understand their requirements and we always enjoy a challenge thinking outside of the box to provide bespoke leading edge survey solutions for any situation.</p>

Measured building surveys

Measured building surveys

Architectural floor, roof, lease, area, legal and conveyance plans, elevations, cross sections, reflected ceiling plans, 3D wireframes, rendered CAD models, BIM models, verticality profiles and monitoring, fly throughs, precise floor slab surveys... all using the latest Bluetooth linked laser measuring equipment and software. Provided as 2D CAD drawings or 3D models in AutoCAD, Revit, BricsCAD, ArchiCAD or Sketchup.

Movement monitoring surveys

Movement monitoring surveys

A monitoring survey can detect if or how far a building or structure has moved over time. The survey process involves monitoring specific markers at regular intervals, which can be daily, weekly, monthly, or even annually depending on the nature of the job.

Topographical land surveys

Topographical land surveys

State-of-the-art robotic one-man Total Station theodolites and centimetre accurate Ordnance Survey linked GNSS/GPS equipment allow us to capture site data to provide accurate land surveys in a range of formats including DWG, DXF, PDF, XYZ, and RVT.

The level of detail can vary from a simple level survey with basic line work to a fully annotated plot of a complex urban scene.

3D laser scanning

3D laser scanning

Fast and highly accurate colour or monochrome 3D data captured indoors and out, measuring your site in three dimensions to provide a comprehensive 3D Point Cloud of your land and property.

Our handheld mobile rapid LiDAR mapping system (GeoSLAM) allows for fast data capture, without complex set up or lengthy data processing. It's ideal for use indoors, underground and in environments where traditional GPS solutions don't function well, even dense woodlands!

Point Cloud surveys

Point Cloud surveys

Our Point Cloud survey services leverage advanced 3D laser scanning technology to capture highly accurate spatial data of your site or property. Using state-of-the-art LiDAR scanners, we create detailed 3D models with millimeter-level precision, offering a faster and more cost-effective alternative to traditional surveying methods.

BIM 3D models and site sections

BIM 3D models and site sections

Full or partial 3D models from gathered survey data produced in a variety of formats to suit your needs for BIM, animations or simply for rendered visualisation purposes. Land surveys can provide digital terrain maps (DTM) with contours and almost instantaneous site sections. Data for sandboxing in Sketchup or topo surfaces in Revit, and XYZ/CSV files for import into CAD.
