Topic:  Geotechnical Aspects of Stormwater Control Measure Design and Construction

Presentation: Video

Summary: The soil composition of many stormwater control measures is vital to achieving

their intended purpose. Determining the elevation of the seasonal high water table is an important step in the hydrogeologic design process for stormwater control measures. Some stormwater control measures require embankments for water storage, infiltration to remove and treat water, and/or liners to retain water to function properly. Critical construction issues include embankment materials, compaction, and outfall pipes; bottom infiltration rate verification, liner materials and installation, and filtration material testing. This presentation will address these issues and provide project examples.

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. Ceccarelli has presented this subject for the National Society of Professional Engineers, the United Kingdom's Autonomous Vehicle Symposiums, ASCE, and other venues.

Topic:  Computational Modeling of Interfaces in Complex Infrastructure Systems

Presentation: Video

Summary: The field of computational mechanics has witnessed significant advancements that have greatly improved our ability to model complex phenomena, ranging from large-scale structures to nanoscale systems, under conditions that cannot be replicated in a laboratory, and often at reduced cost compared to experimental testing. However, many challenges remain in the development of numerical models for complex infrastructure systems and composite materials where multiple components interact through an interface. Interfaces are critical pathways for load-carrying mechanisms that contribute to lifelong performance and structural resilience. Thus, it is crucial for the computational model to accurately capture the interface kinematics and force transfer processes, particularly in the presence of geometric and material nonlinearities, damage, friction and dynamics.

This presentation details the challenges and applications of interface modeling for coupled problems in engineering. I will introduce a new class of formulations that can efficiently handle complex interface interactions in structures and materials. I will discuss a physics-based model for accurate prediction of bond behavior in reinforced concrete (validated by experiments) that quantifies bond resistance from the material properties of steel and concrete constituents, as well as the mechanics of contact between them in the anchorage area. These new and robust interface formulations enable the modeling of complex structures for purposes of health monitoring and life-cycle management that also support the development of emerging materials and novel techniques for enhanced structural resilience.

Topic:  ABC of Unbraced Network Arch Using SPMTs

Presentation: Video

Summary: This presentation will provide an overview of the signature Network Tied Arch Second Avenue Bridge over I-94 and will cover the planning, design, and innovative construction methods that included building the bridge off-site and moving it into place using Self-Propelled Modular Transporters (SPMTs). MDOT, along with key stakeholders including City of Detroit and Wayne State University, desired a signature bridge as the centerpiece of the I-94 Modernization Project to act as a Community Connector - essentially a park-like structure that would promote the safe transportation of pedestrians and cyclists. This 245 ft long, tied arch span carries vehicular traffic, bicycles, and pedestrians and is a first of its kind in Michigan.

The future widening of I-94 requires a much longer bridge than would fit in the existing freeway corridor. Traffic volumes on the depressed freeway approach 175,000 vpd while limited vertical clearance allowed no safe and suitable means of building the new bridge in place. The team was driven to develop a unique approach to constructing a durable signature bridge that could achieve these objectives in an efficient way while prioritizing safety and reduced public impacts.

Moving the bridge skeleton into position during a short closure of the freeway was the only feasible way to meet the objectives of the project without creating significant, long term traffic impacts to the I-94 freeway. Assembly of the steel-concrete hybrid bridge skeleton was performed in a staging area approximately 500 feet from the final bridge location. Furthermore, the assembly lot was located nearly 20 ft above the elevation of the depressed the I-94 roadway. The bridge site was further constrained by an adjacent historic Motown recording studio building that could not be disturbed.

The 5,000,000 pound bridge skeleton was lifted using specialized SPMTs, transported to the final location and rolled across the freeway in July, 2022. The presentation will provide a detailed step-by-step overview of the preparations prior to and operations of this innovative and unique bridge move and the teamwork required to make it a success.
