3D Laser Scanning London

We offer a unique ‘whole building’ approach to measured surveys and 3D scanning London wide, which means everything from the structure, internal and external features and the services of the building are all covered. This results in a higher quality, detail-packed survey, suitable for everything from structural redevelopment and major refurbishment to space planning and lease plans.

With decades of experience and specialist expertise as laser surveyors London and UK wide, employing some of the UK’s finest talent, we deliver a service that’s completely hassle-free.

So whether you’re an architect, local authority, chartered surveyor, property developer or building owner or manager, you can simply give us your specification, and leave the rest to us, safe in the knowledge that everything you need will be delivered to your desk within your specified timeframe, and budget.

What’s more, with every individual 3D laser measured survey overseen by one of our highly experienced principal surveyors, you’ll always know that you’ll be able to trust a Callidus Survey.

A measured survey is a comprehensive survey relating to the external and/or internal aspects of a site, right down to the detail of individual floor plans. All our measured surveys use the latest 3D scanning technology, making them way more detailed and accurate than any traditional hand measuring method could ever be.

Measured surveys are conducted in line with guidance from the Royal Institution of Chartered Surveyors (RICS), which forms the framework of rules for measured surveys of buildings, utilities or land. 

Depending on the scale of a project and specific requirements, measured surveys can take the form of anything from basic floor plans and drawings to highly accurate 3D models. The data collected using highly detailed 3D scanning forms a crucial element of future planning phases, as well as forming the foundation from which all design and development plans are created.

Accuracy and survey quality are vital, as inaccuracies can lead to increased costs, delays and the potential for breaching planning conditions. This is exactly why we’ve invested heavily in the latest cutting edge 3D scanning technology, ensuring we produce the most detailed and precise data sets for our clients’ needs.

Simply send us your specification and we’ll get back to you with a quote for your 3D measured survey.

If you’d like to go ahead, you can either call or email us and we’ll book the survey in for you, doing our best to fit in with any deadlines. All we generally need is an address and confirmation of access, and you can leave the rest to us.

All Callidus measured surveys use 3D scanning and are carried out in strict accordance with RICS Code of Measuring Practice, 6^th Edition (updated Jan 2018).

To be able to put a price to your survey, we need to fully understand your requirements.

Below is our standard list of reminders to help you put together a workable specification:

Internal plans at which floors? To include all service switches, sockets, lights outlets etc.?

Note: Standard plans include windows, doors, door swings, structural walls, partitions, floor-ceiling heights, window heights/positions within floor-ceiling, location of downstand beams, sills, heads, parapets, soffits, changes in floor levels, steps, ramps, all significant sanitary fittings, and incoming services where visible.

Topographic survey (external yard, garden plans)?

External elevations? Which elevations? (Specify which faces).

Any off-site elevations for context or rights-to-light? (Specify which faces). 

Fully detailed (including coursing detail and fenestration) or basic (openings and profiles only).

Internal elevations (basic or detailed)?

Note: Internal elevations in every space will more than double the price of your survey. Please be specific in choosing any internal elevations to minimise costs.

Sections through the building? How many? Do you need these internally elevated? Can you provide a plan mark-up of specific required positions?

3D scanning is the latest way of collecting spatial data on a site. The equipment is able to measure and record millions of data points per second within its field of vision. These build up a point-cloud, which depicts the building or structure to be captured.

Each point carries data, such as X, Y & Z co-ordinate, reflective intensity and colour. For every project, there will be multiple point-clouds collected from individual scanner locations. These clouds are then stitched together to produce a full, spatially accurate 3D depiction of the space.

Once the point-clouds from the 3D laser scan have been brought together and correctly positioned using GPS references, they can then be inserted into CAD software.

The point-clouds are then sliced into manageable portions, before lines are traced in CAD in accordance with the scan slice. These slices are created in 3D CAD space to produce the plans (horizontal slice) and cross sections and elevations (vertical slices).

The beauty of 3D scanning is its ability to not just depict walls, windows and doors, but also to produce sufficiently detailed data that allows clear sight of internal and/or external features in exceptionally high resolution. Anything from power sockets and exposed wires, to architectural mouldings and even individual bricks, can all be picked out in the finest detail to be drawn up if necessary.

3D laser scanning has become the preferred method of data capture for measured surveys for a number of reasons. Firstly, it allows for very fast data collection, with the capability to capture vast quantities of data in minutes. Secondly, it is able to capture the elements of the survey in fine detail.

And then there are the safety benefits. The whole process of 3D scanning is contactless, which means our laser surveyors in London don’t need physical access to any element of a building in order to measure it. It also means we can measure hazardous environments without putting personnel at risk.
