Callidus Surveys

Our uniquely developed ‘whole building’ approach to measured surveys and 3D scanning London wide, means the structure, internal and external features and the services of the building are captured and drawn to create an accurate, coherent model of your building. The result for you is a high quality, detail-packed survey, suitable for tight-tolerance structural redevelopment and major refurbishment, 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 best-trained personnel with an eye on your own service needs, we deliver the hassle-free, accurate survey you expect.

So whether you’re an architect, local authority, chartered surveyor, property developer or building owner or manager, you can simply give us your specification (or we can guide you through the process if required), and leave the rest to us, confident that the project documents will land on your desk when you need them and within budget.

Every individual 3D laser measured survey is overseen and quality checked by a principal surveyor, so you’ll always know a Callidus Survey can be trusted.

Callidus Surveys is known for its specialist expertise in building surveys, topographical surveys, movement monitoring, plus 3D laser scanning, CAD surveys and floor plans. 

We have worked in an array of buildings, from prestigious, heritage and listed properties, to new developments and private homes of all sizes.

A measured survey is a 2D or 3D model of a building or structure which provides an accurate representation of the external and/or internal aspects of a site. It can be as detailed or basic as required – either basic block outlines or to accurately capture the detail of individual bricks, internal fittings and other fine detail. 

Depending on the scale of a project and specific requirements, scanned measured
surveys can take the form of sets of 2D plans , elevations and
sections or 3D models. The data collected by 3D scanning provides a
reliable foundation for all design and development projects.

All Callidus surveys employ 3D laser scanning technology, enabling much more detailed and accurate information than any traditional hand measuring method can hope to achieve.
For a journey through the differences between the two, take a read of our Brief Guide to modern measured building surveys (5 minute read), which highlights why modern building professionals should be specifying high-quality laser surveys and how to identify low-quality, low-skilled interpretations prevalent in the industry.

Callidus measured surveys are conducted in line with guidance from the Royal Institution of Chartered Surveyors (RICS), which sets out the framework for professional quality measured surveys of buildings, utilities and land. 

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. Or, if you need guidance through the specification process, we can help you with our simple ‘menu’ of services and options.

After receiving our quotation (with easy-read specification) 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 and we’ll be as discrete and efficient as possible on site.

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

To be able to put a price to your survey, we need to fully understand your requirements to make sure that what you need is delivered.

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). Or let us know your specific requirements.

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?
