Guntert & Zimmerman Partners with Leica Geosystems

Starting in late 2008, Guntert & Zimmerman (G&Z) and Leica Geosystems partnered together with the goal of 3D stringless technology to a customer base focused on ride smoothness.  No one has every argued about the huge potential benefits of 3D stringless paving; however, prior to this time, stringless technology was widely considered by contractors to be more suited to airfield paving and highway paving under less stringent smoothness specifications.  This perception was changed in late 2009 when G&Z and Leica Geosystems partnered with Flynn Construction of Dubuque, IA on their 10.5 mile Highway 65 Demonstration project near  Mason City, Iowa where Flynn’s G&Z S850 paver was controlled using Leica’s industry-standard LMGS-S stringless concrete paving system. 

Under Iowa’s very strict zero blanking band smoothness specification, Flynn earned 100% of the available smoothness bonus and did zero grinding.  The smoothness achieved on the Flynn I-65 project established a new paradigm using Leica’s LMGS-S,  ride was indisputably proven to be as good as the best stringline-guided slipform paving. 


Since Fall of 2009, G&Z and Leica Geosystems have successfully commissioned nine Leica stringless installations that have been used on ten different projects around the United States and Canada.  G&Z and Leica Geosystems are committed to taking this technology for the concrete paving industry to new levels.

Guntert & Zimmerman is happy to announce that starting in the Spring of 2011 the G&Z S600, S850 and S1500 mainline concrete pavers will all be available with “Direct Connect” software interface, facilitating the Leica system to communicate directly with G&Z’s Networked Microprocessor control system.  This significant enhancement will simplify installation and improve the performance of the machine interface with Leica 3D controls.  3D machine control solutions for G&Z’s PS1200 Placer Spreader will also be available.

To better service our customers, Leica Geosystems and Guntert & Zimmerman conducted intensive cross-training this winter of their respective sales and service teams with the goal being that Leica sales and service personnel will be expanding and enhancing their knowledge of slipform paving technology and vice versa to better support our common customer. 

G&Z’s successful 24/7 service hotline will be expanded to support our Leica Geosystems users.  Leica Geosystems also manage a service hotline to support users of Leica 3D stringless paving technology worldwide.
