Using Trimble X9 laser scanning, AKN achieves point cloud accuracy well within 3mm at standard indoor survey distances. CAD drawing accuracy for standard floor plans and elevations is typically ±5mm depending on building complexity. For heritage or highly detailed structural work, tighter tolerances can be discussed at the quotation stage.

A point cloud is a three-dimensional dataset made up of millions of spatial measurement points captured during a laser scan. Each point has an X, Y and Z coordinate in space. When combined, these points form a precise digital representation of the physical environment that can be used to produce drawings, 3D models and BIM outputs.

Point cloud data is delivered in .RCP, .E57 or .LAS format as standard. CAD drawings are delivered as AutoCAD DWG plus PDF. If your practice requires Revit-compatible geometry or specific BIM outputs, let us know at the start of the project.

Yes. Laser scanning is one of the most accurate and efficient methods for producing measured building surveys. Floor plans, elevations, sections and roof plans can all be produced directly from point cloud data captured on site.

Yes. Laser scanning is non-contact and non-intrusive, making it particularly well-suited to sensitive, listed and protected buildings. We regularly survey heritage structures requiring detailed recording for conservation, planning or restoration purposes.

Yes. Point cloud data from the site can be modelled into a 3D BIM-compatible model in Revit or equivalent platforms, depending on project requirements. This is particularly useful for complex refurbishments, extensions and developments where an accurate existing-condition BIM model is required for design work.

Most standard commercial and residential buildings can be scanned within a single day on site. Large multi-storey buildings, complex industrial facilities or sites requiring very high scan density may require two days. We confirm the programme when reviewing the project brief.

Processed point cloud data and CAD drawings are typically delivered within 3–5 working days of the site visit for standard properties. We confirm the turnaround at the time of instruction.

Not usually. For most projects we can provide a fixed fee quotation based on a description of the building, its size and the deliverables required. We will ask the right questions upfront to ensure the scope and fee are accurate before any site visit is confirmed.

Yes. Where site topography or a full measured building survey is also required, we can carry out the work on the same visit, avoiding a second mobilisation and reducing overall survey cost.

Yes. We regularly work across North and East London boroughs as well as our core areas of Hertfordshire and Essex. The M25 corridor and Greater London fringe are well within our regular working area.

Yes. AKN holds Constructionline Gold and SSIP accreditation. These are commonly required by architectural practices and main contractors as a minimum for supply chain approval.
