Amberg system saves months of fieldwork on SMART Project

Written by jrood

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.
