2014 Grand Award Winners - EnSafe Inc. and Smith Seckman Reid, Inc.

EnSafe Inc. 

(TDOT Facility Surveying & GIS Data Management - Surveying & Mapping Category)
In support of the TDOT Statewide Environmental Services contract, EnSafe surveyed and mapped 72 TDOT facilities—totaling over 850 acres—using a Topcon Pulse Total Station, complete with our custom data dictionary of feature entry codes, to collect site attributes. The data were uploaded to a Microsoft Access database for QA/QC and then into an ArcSDE database. ArcGIS ModelBuilder routines were run to build lines and polygons from the survey point data, and our custom Python script applied symbolization that was stored in the database as representation.
EnSafe’s workflow design and custom automation offered a cost savings to our customer—the equivalent of one full-time employee for one year—by significantly reducing draft and field survey time.

Smith Seckman Reid, Inc. 

(Wolf River Boulevard Connector - Transportation Category)
The final segment of Wolf River Boulevard consists of approximately two miles of four lane roadway with shoulders and bike lanes, two bridges with protected pedestrian crossings, five oversized box culverts, one pedestrian underpass, and two new traffic signals. Wolf River Boulevard is enrolled in Audubon International’s Silver Signature Sanctuary green certification program. The program blends wildlife habitat conservation, water use efficiency, water quality preservation, and other areas of environmental protection with human use of the project. In August 2013, Wolf River Boulevard was the first roadway in the world awarded Silver Certification for accomplishments in sustainable design, construction, and management.

2014 Award Winners - Geotechnology, Inc. and EnSafe Inc.

Geotechnology, Inc. 

(The Memphis Pyramid - Special Projects Category)
Geotechnology performed the initial study and detailed seismic evaluation of the ground conditions, liquefaction and seismic slope stability for the iconic Memphis Pyramid. Geotechnology faced difficult site conditions but used unique approaches to provide seismic information and develop performance criteria for specialty design-build foundations. Geotechnology continued its role during Below Ground Seismic Construction to monitor the work and provide input when changes resulted from varying ground conditions Throughout the construction, the work is estimated to create roughly 16,000 construction jobs and an additional 300 -400 jobs once the facility is opened, providing a huge boost to the area’s economy.

EnSafe, Inc. 

(Stormwater Runoff from TN Highways - Studies & Research Category)
EnSafe was asked to characterize contaminants on the Tennessee Department of Transportation’s right-of-ways and determine if those contaminants were transmitted through stormwater runoff.
EnSafe proved that contaminant levels generally met applicable water quality standards. This allowed our client to successfully challenge three Total Maximum Daily Load analyses from the Tennessee Department of Environment and Conservation which listed our client’s Municipal Separate Storm Sewer System Permit as a contamination source. EnSafe also revealed a significant paradigm change, proving that pathogen contamination in stormwater does not require a warm-blooded animal source but can simply result from pathogens living in the ecosystem.

2014 Grand Award winners Barge Waggoner Sumner & Cannon and LDA Engineering

Barge Waggoner Sumner & Cannon, Inc. 

(Beaver Creek WWTP Decommissioning - Environmental Category)
The Beaver Creek Wastewater Treatment Plant Decommissioning was a financial, social, and environmental stewardship success story. Over 16,500 tons of concrete (enough to lay 28 miles of sidewalk), 425 tons of steel (equivalent to 38 school buses), and 300 additional tons of debris were recycled. One construction dumpster was landfilled and 720 construction dumpsters of material were recycled. The construction crew worked seven days a week, 12 hour days, to finish 109 days ahead of schedule and at a net cost of only $74,700 after recycling efforts. The project resulted in a clean, 42.5-acre site for redevelopment in Dothan, Alabama.

LDA Engineering 

(Spring Creek 1A: Horizontal Directional Drilling - Small Projects Category)
LDA was selected to provide professional services to the City of Morristown to develop plans and specifications for a troubled section of sanitary sewer that needed rehabilitation. The project involved the rehabilitation of a line adjacent to Stubbelfield Creek, passing narrowly under a warehouse with foundation issues to a manhole located inside the fully functioning warehouse. This project was unique, because typical rehabilitation methods could not meet all of the design constraints, and horizontal directional drilling was used to replace the 15-inch gravity sewer pipe. Services included design, construction administration, resident president representation, and coordination with City representatives.

2013 Grand Iris Award Winner EnSafe Inc

EnSafe Inc

NSA Mid-South faced the challenge of large, low concentration TCE solvent plumes with multiple, overlapping source areas distributed over 72 acres, a legacy of various maintenance activities during World War II.  EnSafe was able to identify multiple residual groundwater hot spots and working in collaboration with TDEC, the USEPA, and the US Navy, selected enhanced in-situ bioremediation as the most feasible remedy. Treating in place meant groundwater hot spots could be collectively addressed in a cost-effective manner and provides a long-term solution, minimizing interruption to site development, and succeeding in meeting the Navy’s environmental restoration goals.


2013 Award Winners AMEC

AMEC Studies, Research and Consulting

Following the May 2010 flood in Nashville, a multi-agency partnership was formed called the Nashville Situational Awareness for Flooding Events Program. AMEC was hired by Metro Water Services to join the program and develop products and processes that would carry out the mission of Nashville SAFE; to address the needs for improved coordination, more and better data, and trained personnel. For this project, AMEC created the Watershed Advisory Guide, developed emergency procedural documents, produced a training video, and developed other techniques that helped Nashville SAFE set the new standard for flood warning systems in the Southeast.

AMEC Survey and Mapping

The EcoSpatial Information Database was designed by AMEC as a foundation for an ecosystem‐based approach to management. By centrally warehousing ecological resource data, such as scientific reports and journal articles, along with bibliographic information and spatial data, the system provides an organized, all-encompassing archive that will allow the Bureau of Ocean Energy Management to have a better understanding of ocean habitats and marine organisms. The system is accessible through a cloud based mapping interface with elaborate text and geographic search functionalities to streamline federal decision making and the regulation of oil and gas development activities with proper environmental
