Company Profile

Callidus Surveys was incorporated in 1999 under the stewardship of three experienced principal measured surveyors.

Having surpassed its conservative three-year business plan within six months, Callidus grew steadily over a number of years, establishing itself as an industy-leading, trusted specialist in accurate and time-efficient production of measured building surveys.

By 2008, Callidus had built a solid client base and a positive reputation in the surveying and geospatial world, which proved to be a powerful asset through the tough trading conditions of the following few years.

In 2012 Callidus started using Faro laser scanners and by 2016, with significant investment in scanning hardware, software and training, the traditional method of hand-measured surveys was dropped. Currently, all of our building surveys are laser-scanned, with hand measurement reserved just for site-checks and localised fine detail.

Today, under the directorship of two of the original 3 owner-managers, Callidus operates as a respected industry specialist with the knowledge and expertise to back it up. The directors take pride in keeping their hands-in on scanned surveys (and other engineering surveying projects) to make sure we not only keep our fingers on the pulse of the industry, but also retain a healthy connection to the coal-face. Our attention to customer service and client-focussed specification has always been a key feature of the Callidus offering.

Callidus has a historical portfolio of over 2000 survey projects – including over 300 heritage and listed buildings – each one quality-checked and signed-off by one of the principals. Survey project values range from £600 to over £30,000, undertaken for Architects, Developers, Local Authorities, Chartered Surveyors, and building owners and managers.

Below are some of the larger prestigious listed buildings of which Callidus is proud to have been invited to produce full measured surveys:
