Amberg system saves months of fieldwork on SMART Project

Written by 

The Sonoma-Marin Area Rail Transit (SMART) is an initiative in Northern California to provide a new passenger rail service along 70 miles of an existing Northwestern Pacific corridor. With the corridor having been out of service since 1994, the lead designer, HDR Engineering, required a high precision, as-built track geometry survey of the existing infrastructure.

The northern 60 miles of this task was performed by Cinquini and Passarino, Inc., (CPI) a land-surveying firm based in Santa Rosa, Calif.

The original estimate to complete the survey with conventional track surveying methods was three months. CPI deployed the Amberg Technologies' GRP Track Measurement system, which allowed the firm to complete the entire survey in less than two weeks. The Amberg GRP system allowed CPI to provide the survey quicker, with more data and at a higher accuracy than capable with conventional methods.

Amberg Technologies began distributing the GRP system to the U.S. last year through Chicago based distribution partner, the Kara Company.

The current edition of The American Surveyor magazine features the success of Cinquini and Passarino, Inc., using the Amberg Technologies' GRP track measurement system on the SMART project in Northern California.

The GRP is a modular, trolley-based hardware platform. Combined with the Amberg Rail software suite, the system is used for a wide array of applications within both the freight and passenger rail industries, including:

• As-built acceptance surveys

• Track geometry surveys

• Real-time track adjustments for direct fixation and embedded slab track construction (High Speed Rail Construction and Light Rail Construction)

• Real-time clearance analysis

• Asset documentation

• Mobile, 3D laser scanning

• Tamping surveys.
