Success Stories

Over the years, Civil Data Systems has successfully worked with numerous clients across the country in a variety of different situations.

Grace Church, Charleston, South Carolina
An historic church that survived the Civil War and the great Charleston earthquake of 1886 now faces a new threat from structural cracking in its masonry walls and steeple. A local structural engineer enlisted Civil Data Systems to help with continuous remote monitoring of these cracks to help design and evaluate preservation efforts.

Residence, Frankfort, Kentucky
As part of a legal settlement regarding allowable vibration levels from an underground aggregate mine, Civil Data Systems provides Internet-enabled data services for the continuous remote monitoring of a nearby residence.
The CDS web site integrates data from a variety of displacement and vibration sensors from multiple vendors.

Michigan Street Bridge, Sturgeon Bay, Wisconsin
In the city of Sturgeon Bay, Wisconsin, a nearly eighty-year-old rolling bascule lift bridge carries the only road through downtown. To help with life extension efforts, Northwestern University has operated continuous remote monitoring systems on the bridge since 1995. Civil Data Systems provides
the Internet-enabled data distribution and display technology that keeps highway officials informed.

SR-66, Highlands County, Florida
In early 2001, sinkhole-like subsidence occurred under SR-66 near Sebring, Florida. The subsided road was repaired with a land bridge and clinometers and time-domain reflectometry (TDR) instruments were installed to alert highway officials of any additional soil movement. The Civil Data Systems web site allows for easy comparison of current TDR waveforms with
historical norms.

Trump Tower, Chicago, Illinois
In 2005, Civil Data Systems installed an Internet-enabled construction monitoring camera for the foundation contractor for the Trump Tower construction in downtown Chicago. The camera was mounted on the roof of
an adjacent building for a complete view of the excavation site. The CDS camera system provides live images of the construction site and a complete photographic archive of the history of the project.

Historic Residence, Washington, District of Columbia
In 2004, crack displacement and vibration transducers were installed in an historic house in downtown Washington, DC. Government historians had become concerned over cracking in the house and, in particular, the effects that nearby road reconstruction might have on crack growth. Civil Data Systems provided a web site which allowed for easy comparison of
long-term trends and dynamic events recorded by the displacement and vibration sensors. This service helped to assuage the historians’ fears that
the adjacent road construction was exacerbating the cracks in the
150-year-old house.

Olive 8 Development, Seattle, Washington
Excavation for a new high-rise building in downtown Seattle raised
concerns about the effects that the deep excavation might have on nearby buildings, including a hotel on a shallow foundation and a 50-story office building. An automated survey station was installed on a roof overlooking the construction site to monitor soil movements around the excavation.
Civil Data Systems software autonomously performed the necessary calculations to convert the survey instrument readings into displacements
and displayed the displacement data on a secure web site for analysis by construction engineers and researchers.
