CONNOLLY AWARD

The Connolly Award was named in honor of James B Connolly, former Savannah District, US Army Corps of Engineer’s employee, veteran of the Spanish-American War, Olympic Gold Medalist in 1896 and distinguished author.

Presented for notable contribution to engineering by a civilian or uniformed service engineer bringing recognition to our fair city of Savannah.  This plaque will first be awarded in 2005.

Short Biography: James Brendan Connolly (1868-1957) was the first winner of an Olympic Gold Medal, a veteran of the charge up San Juan Hill during the Spanish-American War, candidate for Congress in 1911 (Progressive Party), and one of America’s foremost writers of maritime tales, having authored some 25 full-length works and more than 200 contributions to journals and newspapers. He also served with the Savannah District, U. S. Army Corps of Engineers. Born in South Boston, Massachusetts, one of twelve children, Connolly came to Savannah in 1892 at the invitation of his brother Michael, who worked for the Savannah District and arranged a position for James. In the next three years, James served in various positions, including clerk, recorder of tidal and river current fluctuations, pile-driver inspector, and dredge inspector. Connolly liked the District Engineer, Captain Oberlin Carter, who moved Connolly to rivers and harbors work after he became bored with

a clerk’s duties. Connolly enjoyed himself in Savannah, where he indulged in many athletic events, including track meets and football. He captained the Catholic Library Association (CLA) football team to a 36-0 win over the Young Hebrew Association, scoring three touchdowns himself. For a while, he also wrote the sports column for a new weekly paper called the Lamplight. In 1895, Connolly was ready for new adventures. He had never graduated from high school, but took correspondence courses for six months and, encouraged by Dean Nathaniel Shaler of Harvard University, passed Harvard’s entrance examination in October 1895. He entered the university as a 27-year-old freshman, but left it within a year—despite being told he might not be readmitted—to participate in the first modern Olympic games, held in Athens. Harvard’s attitude offended him, and he never returned to complete his education there.

In Athens, Connolly won the gold medal (actually, silver medals were then awarded for first place) in the triple jump despite the fact that the triple jump in Athens was two hops and a jump rather than the hop, skip, and jump for which Connolly had trained and was the American champion. He threw his cap a yard beyond the mark set by his main competitor and then managed to leap even beyond the cap, just short of 13.5 meters, a mark that was short of his personal

GEL Geophysics recently completed a comprehensive subsurface utility engineering (SUE) investigation in Charleston’s historic City Market. This Quality Level B SUE investigation was performed for Davis & Floyd, Inc., the engineering firm that is designing a major phase (Division III) of the City of Charleston’s Market Street Drainage Improvement Project. The City Market sits at the lower end of the Market Street Drainage Basin, a roughly crescent-shaped basin comprising approximately 55.5 acres. In the engineering and subsurface utility arena, the historic Market Street area in downtown Charleston is known for its high utility density, and for the ages and number of out-of-service utilities as well as other subsurface features which could prove to be conflicts with future construction activities. Formerly Major Daniel’s Creek, this area was filled 200 years ago to create the City Market. In short, the shallow subsurface within the project footprint is challenging on many levels. Compounded with rising sea levels over the last 200 years, the existing storm water drainage system, consisting of a failing and sediment-filled brick arch conveyance system and outdated surface drainage structures, simply cannot adequately and efficiently drain the storm water.

Detailed subsurface utility information was needed in order to facilitate the design of the project. The overall project will include the construction of major storm water structures, including drop shafts and deep tunneling, as well as streetscape and grading improvements and utility undergrounding. This project addresses the flooding issues within the City Market, and will include North & South Market Streets from Meeting Street to the terminus of Concord Street. This area is a popular attraction for tourists and residents alike with its local artisans, historic structures, and retail and restaurants flanking it on all sides.

The SUE Investigation included the use of multiple technologies, including ground penetrating radar and electromagnetic pipe and cable locators. Due to the known density and complexity of buried utilities, targeted areas were also scanned using a 3-D Radar Tomography (RT) system. The RT system collects 3-D data which provides a virtual “CAT-scan” of the subsurface. Following the collection and surveying of all subsurface utility information, the SUE information was provided in AutoCAD format and overlain onto existing preliminary design plans, along with utility depth information in a 3-D pipe network. As the drainage

Chris Landt

Design for stormwater management on developed sites has evolved greatly over the past 25-years to adapt to changing water quality criteria, watershed management plans, and land development patterns.

Stormwater regulations are changing from the past historical focus. Pollutants are now a public concern with regard to any unwanted discharges that could commonly threaten the health of beachgoers, affect potable water plants, and decrease the recreational use of our water bodies. While unwanted discharge sources such as agricultural runoff, septic tanks, and wastewater treatment plant effluent are being studied for potential solutions, another issue of the treatment of urban stormwater runoff presents its own unique set of challenges.

The engineering community must find new ways to manage runoff to meet the evolving treatment standards. While water quality standards have been changing, design philosophies must also change to use multiple strategies to satisfy needs for storage, infiltration, and treatment systems to achieve those standards.

Stormwater treatment system manufacturers have responded to new regulatory drivers by developing

new technologies capable of reducing pollutant constituents.

Such devices are not always viewed as being compatible with LID or Green Infrastructure design practices, but when compared in terms of their effectiveness, they may accomplish more than their green infrastructure counterparts. This presentation will compare the function and effectiveness of “natural” treatment systems to manufactured treatment systems to demonstrate their compatibility with the intent of stormwater focused treatment and quality regulations.”

EUROPEAN DoD INFRASTRUCTURE CONSOLIDATION David Ziegman

Dave Ziegman is a Senior Vice President and head of Woolpert’s Military Market Group. He represents 30 years of design planning and consulting experience for both public and private clients. He has extensive experience with the planning process by working with small groups, leading large public meetings, and making formal presentations to decision-makers. His project work includes planning and design for military facilities, public and private land use,public facilities, transportation projects, and commercial and residential area/site development projects. He has supported numerous federal government clients that include the U.S. Army Corp of Engineers (USACE), AFSOC, and USAF.

As part of the Department of Defense’s European Infrastructure Consolidation program—a nearly two-year-long effort to ensure the long-term efficiency and effectiveness of the U.S.presence in Europe—Woolpert provided strategic planning support to HQ USAFE and HQ AFSOC.The plan investigated a potential relocation of the 352 Special Operations Wing (352 SOW) fromRoyal Air Force Mildenhall England to Spangdahlem Air Base, Germany. The project included preparation of a master plan for the beddown at Spangdahlem AB and ultimately led to user requirements documents for nearly $350 million of facility projects and military construction required to support incoming mission and personnel.

Workshop participants will leave the presentation with an understanding of:• the process with which the task was approached• the ways in which site and cultural challenges were overcome• the method used to ensure multiple stakeholders’ input was effectively used• the lessons that can be learned from AFSOC’s proactive approach to

relocation

The forward-leaning nature of this project set it apart from similar development plans. When AFSOC recognized that a relocation request was likely imminent, they identified where to relocate given interests and missions. AFSOC’s willingness to position itself ahead of a complicated process by identifying a potential opportunity to relocate and positively,symbiotically impact the direction of Spangdahlem AB’s construction should be mimicked for future tasks. The organization was able to gain a geographic and strategic advantage during thisprocess through their actions and plans—making the project worthy of deep analysis.This workshop will showcase the exceptional cooperative planning between myriad stakeholders, including HQ AFSOC, HQ USAFE, 52nd Fighter Wing (Spangdahlem AB) and 352 SOW (RAF Mildenhall), which has ultimately prepared the groups for the realignment of overseas U.S. warfighters within the European Command. Attendees will also learn about the project’s sustainability and resiliency components—including low-impact, climate-appropriate design; energy efficiency; and water, wildlife and forest protection.

Accelerated Bridge Construction (ABC):

ABC is bridge construction that uses innovative planning, design, materials, and construction methods in a safe and cost-effective manner to reduce the onsite construction time that occurs when building new bridges or replacing and rehabilitating existing bridges

Prefabricated Bridge Elements and Systems

PBES are structural components of a bridge that are built offsite, or near-site of a bridge and include features that reduce the onsite construction time and the mobility impact time that occurs when building new bridges or rehabilitating or replacing existing bridges relative to conventional construction methods.

This presentation will discuss easy installation and proven durability of prefabricated bridge elements with a variety of materials, shapes, sizes and end treatments. The inherent strength, durability, cost-savings, and rapid installation of prefabricated bridges have made them a leading accelerated bridge approach. Prefabricated, modular concrete arches, steel and aluminum structural plate and steel truss systems require

less material than comparable field built structures, for a lower initial cost. Off-site fabrication ensures tight adherence to specs, less on-site work, and quality control of modular units. Installation is fast — usually within days, compared to the weeks or even months required for field built structures. This minimizes road closings and detours. Prefabricated bridge components ensure a long life cycle and low life cycle costs.

Topics covered will include:

• Brief discussion of the FHWA ABC program.

• Introduction of structural plate and precast concrete arch buried bridge structures.

• Introduction of steel truss bridges for pedestrian and vehicular loadings.

• Application examples.

FOOD - WASTE TO ENERGY George Fertal

George Fertal is an Associate Vice President at CHA Consulting, Inc., a full service engineering and construction management firm that provides services to clients throughout North America. His current professional focus is on industrial and energy markets with concentrations on energy improvements. Mr. Fertal has over 25 years’ experience in operations and manufacturing, leading projects at various levels as a project engineer, project manager, plant engineer, plant manager, and vice president of operations. He is active in the Society of Plastics Engineers, Society of Manufacturing Engineers, and served as a Trustee for Georgia Piedmont Technical College’s Foundation until 2015.

The already daunting task of achieving energy efficiency is compounded by the innate complexity of the food industry. The presentation discusses the benefits of energy efficient practices via a walkthrough of a waste to energy case study addressing CHP power generation fueled by the vertical start-up of a 6.5MG anaerobic reactor for industrial wastewater pretreatment in the food service industry.

The project was defined by five goals: compliance with industrial pretreatment discharge limitation, elimination of off-site waste disposal, reduced energy and operating expenses, use of design-build delivery method, and the securing of federal energy investment tax credit. Two operations existed on the site that combined produced 605,000 gallons per day of process wastewater, required off-site disposal at considerable expense, generated discharges under an industrial discharge permit, and consumed large amounts of energy. Optimization of the site encompassed anaerobic pretreatment and an energy recovery evaluation and plan. Anaerobic pretreatment lowered overall sludge production and improved the average effluent quality as well as the gas quantity

and quality. The following energy recovery evaluation was based upon proof of the gas asset and considered multiple alternatives, which were evaluated using an economic model to determine IRR. A sensitivity analysis was performed to evaluate the impact of sensitive factors on IRR.

The energy recovery plan included gas compression and drying at the digester site, a single containerized engine-generator with provisions for an additional unit, and excess biogas to flare or direct firing in a boiler for heat. Following the selection of the design-build delivery approach, the design was completed in January 2015 and full power production achieved in July 2015. The presentation will conclude with a list of the benefits achieved by this project, including power generation, reduced energy usage, and lowered discharge and emissions.
