As the technologies involved in automated warehousing become more and more advanced, so too must the tools used to measure and assess these floors. James Dare, Flooring Consultant at Face Consultants Ltd, delves into the world of floor surveying and explains why using the correct high precision equipment is a make-or-break factor for surveyors, contractors, integrators, and end users alike.
In the up and coming world of automated warehousing, the installations and systems used are becoming more and more sophisticated as new ideas and technologies are developed and deployed. In much the same way, the technologies for surveying floors aim to keep up with this demanding industry.
At Face Consultants and CoGri Group, we are always developing new equipment and software to keep ahead of this fast-paced industry and we continually carry out studies to offer the best service for our clients.
This article will help describe the complexities of measuring floors to tight tolerances and how not opting for the correct equipment can be problematic for surveyors, remedial contractors, flooring contractors, system integrators and end users.
There are three main reasons to ensure your equipment must achieve the required accuracy:
So, what now?
The floor will either be remediated unnecessarily, or further checks will need to be made over the area using more accurate equipment to confirm if there is an error or not. Both processes take time and, of course, an added cost.
What happens now?
– Nothing, as it won’t be checked or remediated.
If there is an issue with the floor later down the line and the area is checked using more accurate equipment, then there may be contractual issues as described in point 1.
This question doesn’t only relate to floors but all kinds of services.
After all, you wouldn’t see engineers from a precision engineering workshop leaving their micrometre on the side and instead using a tape measure to measure to 0.05mm! Not only would it be inaccurate, but the client wouldn’t be receiving the part or service they are paying for and rightly expect.
The newest trend coming through the industry for surveying floor surface regularity is 3D scanning.
Although the resolution of a 3D scan can be very good and outputs “pretty pictures”, what is the actual accuracy of a scan and how useful is the data?
Some companies are claiming an accuracy of +/-1mm (although even this may not be good enough in some scenarios), which is tighter than the claims of the scanner company itself when testing in perfect conditions.
From studies in working conditions, using some of the best equipment and processes on the market, the accuracy is more like +/-2mm.
Don’t just take my word for it:
We are always carrying out studies to develop our understanding of the capabilities of 3D scanning and will be continuously sharing the results from these studies. We strive to be at the forefront once the capabilities of any survey method have proven to be suitable for the industry.
CoGri Group and Face Consultants are seen as the global leaders in floor testing and have been for many years. We develop new devices and software to assist in measuring floors.
Face Consultants has a 3D scanning division and is pushing the limits of the equipment and software to get the best results. When we scan floors using this equipment, we do so to get a general idea of the floor profile, determine overlay thicknesses, or investigate large movement in floors from settlement or heave, but not, as yet, to determine compliance with floor flatness specifications.
So, the question should be:
If 3D scanning is considered suitable for measuring tight tolerances by some other companies, why are Face Consultants and CoGri not promoting the use of it for these applications?
An article written by the CoGri Managing Director can be found in the link below which describes one of the studies carried out to determine the usability of 3D scanning. This is available here.
