NEW HOSPITAL BUILDING

Job report – the positioning system LIPOS supports continuous flight auger drilling

More than 1000 piles

The available land required substantial foundation work before it was able to support a whole hospital. In an area of 23,000 m², 1,310 piles had to be installed. All piles have a diameter of 630 mm and are being installed using the CFA (continuous flight auger) method. The maximum depth of the foundation piles was 16 m..

A LB 28 drilling rig was used, which was equipped with the LIPOS positioning system for the first time.

Additional monitor with digital plan

The digital drilling plan could be transferred to the LIPOS positioning system in the Liebherr machine in no time.

In an additional screen, the driver sees jobsite data and pile lists as a template for work to be carried out.

Ground markings not necessary

The LB 28 can be manoeuvred with ease to each of the 1,310 drilling points without the need of any iron stakes or colour markings for orientation.

Fast approach to the drilling points

The LIPOS positioning system played a decisive role in simplifying the work steps: without this system the drilling points would have to be newly measured, drawn and marked at least three times a day.

COMPARISON	with LIPOS	without LIPOS
Drilling plan for the driver	digital	in paper form
Manoeuvring to the next drilling point	GNSS-guided	on sight
Ground markings for orientation	not necessary	peg irons, colour markings, sectional framework
Re-measure drilling points	not necessary	min. 3 x daily

“The LIPOS system has proven itself well on the jobsite. It makes working processes easier and allows continuous real time control and monitoring. Quality management is considerably improved through the automatic recording of the processes.

Drilling points can be quickly selected and the machine positioned. The system is basically self-explanatory for the operator and convinces through easy handling.”
