Topic:  Fayetteville NC Watershed Program – Where we’ve been and where we’re going!

Presentation: N.A.

Summary: The combination of pluvial and fluvial flooding in the rapidly developing city of Fayetteville creates many challenges in flood mitigation, during extreme events as well as smaller more frequent rainfall events. In 2019 city leaders embarked on an ambitious city-wide Watershed Master Plan program to better understand the magnitude and severity of stormwater flooding across the city and proactively develop mitigation projects. City leaders understood that a comprehensive evaluation would support resiliency by providing a pool of prioritized projects for both short- and long-term implementation and leverage resources. This future-forward thinking has proven invaluable, because the city is now equipped with better information about project needs in critical areas, and the detailed studies have been crucial in securing grants. These grant awards essentially offset program costs to date.

The program foundation was established over four years and included a rebuild of the stormwater geodatabase, a city-wide high priority area stormwater asset field survey, guidance for modeling and data visualization, parallel modeling efforts, and methods for prioritizing projects. Master plans for eight of the 15 watersheds have been completed with twenty flood mitigation projects under various phases of design or construction. Other aspects of this comprehensive program are also being developed, including the installation of stream and precipitation gages, plans for future model updates, strategies for updating the GDB, comprehensive Strategic Planning, stormwater asset survey for remainder of city, early flood warning system, and more.

Success of the program is due to the unwavering support by city leaders and the community, continuous collaboration among city and consultant team members and city leaders, and the courage to consider unique opportunities at a scale beyond the typical flood mitigation projects of the past. The program has been fortunate to have a strong Sponsor in our Director who helped us all understand the value of ‘Going Big’.

Topic:  Non-Destructive Testing Methodologies for Structural Assessments

Presentation: Video

Summary: Rehabilitating existing structures requires a thorough knowledge of their in-situ construction and condition. As-built plans often do not exist or may have been lost or not accurately represent what was built. When evaluating capacity, details regarding embedded reinforcing steel, foundation sizes and depths, and qualitative condition are integral parts of the Engineer’s investigation. Visual and destructive testing procedures have been commonly used, but can be time consuming and may not gather enough information. Towards this end, nondestructive testing (NDT) methods have been successfully used in industry to augment these inspections. Though helpful, careful consideration must be given to the particular methods employed to ensure the appropriate field measurements and data reduction techniques are used. This presentation will involve case histories to introduce and demonstrate some of the common problems and solutions encountered by the author through his work in the NDT field.

Topic:  The East Neuse Regional Pump Station - The Design, Construction, and Startup of one of NC's Largest Wastewater Pump Stations

Presentation: Video

Summary: Raleigh Water’s new East Neuse Regional Pump Station is part of a program to supplement the main arteries of their wastewater collection system and also aid in improving service for partner municipalities. This facility will allow removal of flow from the Neuse River basin and the Wendell service area from the existing lift station and interceptor system. In addition, the facility will allow diversion of flow from the Crabtree and Walnut Creek basins during extreme wet-weather events. This project presents CORPUD with an interesting challenge, however— how to design and build a pump station to operate efficiently with dry-weather flows in the range of 20 mgd, while still accommodating wet-weather flows exceeding 100 mgd. Adding to the challenge is the depth of the pump station dictated by upstream river crossings while avoiding inverted siphons or multiple pump stations.

This presentation will discuss aspects of pump station design, construction, and startup. Focus topics include physical hydraulic modeling to optimize the wetwell design, equipment and pump selection to accommodate the wide range of flows, construction challenges including deep excavation, river crossing, pipe connections and installation, and the startup coordination between the pump station projects and the interconnecting infrastructure.

Topic:  Perquimans River S Bridge Replacement

Presentation: Video

Summary: Stretching over the Perquimans River as it drains into the Albemarle Sound in northeastern North Carolina, a historic bridge connected the towns of Hertford and Winfall. Built in 1929, the previous structure carried a 0.6 mile long causeway of US17/NC37 on poor compressible soils including a 650 feet long bridge structure with a 161 feet Warren Truss Swing Span. Continued settlement of the causeway, flooding during severe weather, and deterioration of the structurally deficient Swing Span necessitated the replacement of the entire structure.

To replace the structure, NCDOT has embarked on its first movable bridge replacement through Design-Build procurement. McLean Contracting teamed with RK&K and Hardesty & Hanover to replace the existing structure with a new pile-supported bridge including 27 concrete approach spans and a new Steel Swing Span over the existing navigation channels for an overall length of 2700 feet. The approach spans consist of precast deck panel forms with a cast-in-place concrete deck pour, Florida I-beams, 30in. prestressed concrete piles and integral abutments. The Steel Swing Span consist of a stringer-floorbeam floor system with a lightweight concrete deck, and a Warren Truss.

Technical design requirements included strict adherence to durability requirements for concrete approach spans and concrete substructure, enhanced aesthetics of Swing Span and Control house, protection to turtle species, a new formulation for metallizing the Swing span structural steel, minimizing long-term machinery and electrical costs, and capabilities for remote operation of the bridge.

Topic:  The Yellow Signal Light - Physics, Red-Light Cameras and Engineering Malpractice

Presentation: PDF

Summary: Mr. Ceccarelli introduced this topic to ASCE in 2017. Much as happened since then. For his new presentation, he will review the physics in the Institute of Transportation Engineer's (ITE) practice of determining the duration of the yellow light. Departments of Transportation use this ITE practice. The errors and omissions in the physics cause drivers to systematically run red lights. Red-light camera firms partner with governments, who together use the power of government to exploit these errors for profit.

Departments of Transportation have been adopting the ITE practice since 1965. On March 3, 2020, he and his colleagues convinced ITE to admit that its practice was wrong. ITE published a new practice which adopts their new math equation and rebukes zero-tolerance traffic law enforcement. Most DOTs, like the NCDOT, ignore the new equation. And ITE and the NCDOT continue to inject errors and omissions making everyone run red lights.

Mr. Ceccarelli's presentation includes news of current red-light camera law suits and proposed legislation in North Carolina. We will talk about cities continuing to operate red-light cameras in spite of state engineering boards' rulings that the red-light camera engineering plans lack signature and seal of a PE and/or a firm licensed to practice engineering. We will discuss why NC courts and NCBELS still refuse to oppose a standard of care which does not rise to the requirements of NCGS 89C.

Bio: Brian Ceccarelli has a degree in physics from the University of Arizona. Ceccarelli is a licensed professional engineer. He designs and builds software for engineering and science companies. He is currently employed by the Cooperative Institute for Research in the Atmosphere at Colorado State University.

Ceccarelli became interested in traffic signal timing when the Town of Cary, North Carolina bestowed upon him a red-light camera ticket. That motivated him to research government’s obligations to conform man-made ordinances to the laws of science. Mr. Ceccarelli currently serves as expert witness in traffic signal timing and photo-enforcement in North Carolina and New York.
