Eliza Point Weir Field – Upper MS. River, RM 2.5 Cairo, Illinois
During 2015 Arc Surveying & Mapping, Inc (Arc) was contracted by Patton Tully Marine to
perform hydrographic surveys as required per USACE specifications in the project contract. The
project consisted of the construction of eleven new stone Weirs and three new stone Dikes in
the Mississippi River near Cairo, Illinois. Arc was tasked with performing Existing Condition
Surveys, Progress Surveys, and As-built Surveys for each new structure and our 24 foot, fully
enclosed and climate controlled, survey vessel was assigned to the project. The survey vessel
has on board capabilities for single beam and multi-beam surveys using either DGPS or RTK
positioning.
Arc utilized its staff of hydrographers and surveyors from the Jacksonville, FL. and Memphis, TN.
offices to perform the surveys and mapping required with this contract. With offices in several
regions, including the Mississippi River Valley, our staff has extensive knowledge of the
geographic changes, terrain, and features of each region. We used that knowledge during this
project in finding accessible boat ramps and USACE survey control along the project limits. We
worked closely with USACE staff and inspectors to determine river stage elevations and
conversions to produce NAVD88 elevation data from the NAVD29 benchmarks throughout the
St. Louis District.
Using our RESON SeaBat 7125 and fully automated Survey Vessel, with motion compensation,
we provided current Multi-beam surveys to our client after each barge was offloaded. With the
quick response and high precision surveys the contractor was able to adjust, if needed,
between barge deliveries and continue stone placement with efficiency. In addition, Arc
submitted the Existing Condition Surveys, progress surveys, and As-Built Surveys, when
applicable, to the USACE inspectors and region office. All field submittals were made using
onboard software such as Hypack, Hysweep, and Adobe Acrobat or printed and delivered in
hard copy format. Final submittals prepared by the Arc Jacksonville office, were delivered in
accordance the USACE standards and prepared in Micro station.
