Building Information Modeling (BIM) has developed into the industry standard for medium to large projects and enables continuous collaboration between trades through digital modeling and software.
Although BIM offers many advantages in the planning, construction and operation phases, it is the BIM workflows in the field that really bring the digital twin – i.e. the digital replica of physical facilities – and the construction site together.
This allows construction companies to increase productivity, improve accuracy, and reduce health and safety risks.
How can BIM in the field increase productivity on the construction site?
By creating a digital replica of a construction site, companies can plan in advance exactly where to drill, avoiding on-site decisions and collisions that can lead to delays. This is made even easier by using BIM-compatible devices such as the Hilti Jaibot and the PLT 300 layout tool.
The Jaibot, a semi-autonomous mobile ceiling drilling robot, uses data from the BIM model to position itself precisely before drilling and then mark the holes according to the craft. This not only minimizes the time it takes to find the drilling location, but is also three times faster than manual processing – which significantly increases productivity when drilling thousands of holes.
Advanced layout tools can also read your BIM files by using a built-in laser to locate points from the digital model to the physical construction site. The Hilti PLT 300, for example, acts as a robotic total station to guide the Jaibot to its correct location, but can also be used independently to plan up to 500 points per day with just one worker.
That’s a giant leap compared to traditional methods where two experienced workers are limited to just 150 points per day. The working speed of the PLT 300 is not only released for other tasks, but is simply out of reach for humans.
Improving accuracy with BIM for field tools and robotics
If the construction is designed and planned in advance, it is not surprising that it improves accuracy. This is especially true when the digital twin is brought to the construction site via tools and robotics that eliminate the risk of human error.
The Jaibot and the PLT 300 are designed for precision, as they are guided to the exact location by the BIM data – making miscalculations less likely.
The Jaibot takes it one step further with its tagging feature, which lets any trade know which holes are theirs and removes any on-site confusion. Accuracy not only saves construction companies time, it also saves them the cost of repeating mistakes – which underscores the importance of getting it right the first time.

Reduction of safety risks through digitization of the construction site
With reports from the UK showing 498,000 workers suffered from musculoskeletal injuries in 2018/19, we shouldn’t underestimate the damage that overhead work can cause.
If workers raise their arms over a 90 ° angle for more than 10% of their working hours, the risk of musculoskeletal injuries in the shoulder area increases by one to two thirds.
In the mechanical, electrical and plumbing trades, overhead work is the order of the day and – so far – inevitable.
However, the jaibot relieves the workers’ muscles by drilling holes over their heads – and relieves the workers of physically demanding and repetitive tasks. Not only does this benefit employees, but it also saves employers approximately £ 646 million annually in sick pay and penalties for missed deadlines.
When a robot does the job for you, there is also no risk of dangerous inhalation of dust or hand-arm vibration syndrome (HAVS). The Jaibot’s robotic arm absorbs the full vibration load, while the built-in dust extraction system removes dust before it can get into the air.
By connecting the digital twin to the construction site via BIM to the work processes in the field service, companies can expect improvements in productivity, accuracy and health and safety – all important pillars for the success of a project. BIM-enabled devices complete this offer, increase profits and lead companies into this new age of digitization and automation in construction.
