As demands for precision have risen, the technology enabling more accurate measurements has advanced. Construction professionals can gain much from leaning into this trend. Going beyond the humble tape measure has implications from accuracy to speed to convenience.
LASER MEASUREMENT
Laser measuring tools are at the forefront of this shift. In some projects, digital rangefinders have all but replaced physical tapes and rulers, especially when it comes to measuring larger surfaces.
Because lasers are mostly unaffected by gravity and physical interference, some can achieve precision down to one-sixteenth of an inch at a staggering 400 feet away. At closer ranges, their accuracy gets even higher. Focused light beams also travel quickly, making these measurements almost instantaneous, which is ideal when surveying a large project on a tight schedule.
Optical measuring tools are becoming increasingly more versatile. In addition to detecting length, they can now also act as levels or analyze multiple surfaces simultaneously. While these tools may cost more upfront, the resulting efficiency will compensate in the long-term for the initial expense.
DIGITAL MICROMETERS
Micrometers are a popular alternative for smaller-scale measurements. Analog micrometers are nothing new, but modern versions use internal lasers or electromagnetic signals to deliver faster, more precise results.
Today’s digital micrometers are accurate within 0.001 millimeters, at which point deviations are inconsequential for most projects. Clients with specific requests for material thicknesses will appreciate the assurance, though. These tools provide instant measurements on an easy-to-read screen, minimizing the risk of human error.
Unlike other modern forms of technology, micrometers require little to no training to use. Even cutting-edge versions work the same way as their more familiar counterparts. Ease of use is particularly advantageous for less experienced teams, first-year employees or those tentative about the complexities of new technology.
MEASUREMENT SOFTWARE
Off-site measuring technologies are likewise advancing. Preconstruction measurement software has become increasingly common as more firms have embraced building information modeling.
These programs analyze virtual blueprints and mock-ups to determine a structure’s real-world dimensions. In some cases, BIM software includes such features. Consequently, architects and designers can get automatic measurement calculations as soon as adjusting something within the BIM project.
Software typically measures more than simply length, width and area. It can also calculate volume, structural strength and other mission-critical figures to ensure a project meets client needs. Larger commercial buildings benefit from this in-depth analysis.
AUGMENTED REALITY
Other measuring technologies are not quite ready for large-scale adoption but have potential to make waves in the coming years. Augmented reality is a prime example.
AR projects digital elements over a view of the real world. It’s most common in entertainment apps for now, but many phones already have built-in AR rulers that can measure length as users move their phone cameras. These tools can achieve highly accurate levels, however, distance, ambient light and reflections may limit their reliability.
AR measurements will become consistent and accurate enough for mission-critical use as technology progresses. Using such tools in smart glasses, for example, takes this technology further, as it lets contractors measure distances hands-free. Considering how commercial-grade, mixed-reality headsets have seen additional traction lately, that reality may not be far off.
CHOOSING THE RIGHT TECHNIQUE
Construction professionals can find value across all these branches of measurement technology. No one field shows more promise than the other, as the best technique varies between situations. Consequently, contractors, architects and their teams should consider several or even all of these techniques depending on the task at hand.
Measurement software is exclusively a preconstruction technology, so firms must use something else for onsite readings. However, digital solutions can connect to these virtual models to provide a seamless experience. For example, lasers can upload their measurements via Bluetooth or the internet to update a BIM model for assurance or to tweak blueprints as projects change.
Optical measuring tools are the most reliable at longer ranges, but micrometers and AR may provide increased precision up close. Consequently, the former may be better suited for larger structures, while the latter is ideal for smaller considerations, such as checking materials or cutting timber.
Of course, cost concerns play a role. IT spending at construction companies typically accounts for 1%-2% of revenue—roughly half of what other industries spend. As a result, many firms may lack the funds to justify expensive AR headsets or enterprise-grade software. Such technologies produce a positive ROI eventually, but contractors may prefer to spread costs out by embracing one new solution at a time.
The need for precise measurement in construction will never go away. It will likely become increasingly crucial over time. Consequently, investing in more reliable and efficient measuring technologies is a safe form of tech spending for most firms. These four innovations are just a sample of the ways construction standards are changing.
