Presentation Topic:
The presentation will showcase strategies used in the development of a cost-effective design and construction that allowed this bridge to be designed, approved, and constructed within 24 months. Discussions will include the approaches in the design to address durability and construction techniques that accelerated the construction.
The Harry W. Nice / Thomas “Mac” Middleton Bridge over the Potomac River replaces an existing 1.9-mile, two-lane undivided bridge with a new 61-foot-wide bridge superstructure, with four 12-foot-wide lanes, and a center median to increase traffic capacity, improve safety and facilitate access for maintenance and wide-load vehicles. The new bridge was designed and constructed to cost effectively balance the number of spans against the number of the supporting piers. The design leveraged a combination of prestressed concrete girders in the low- and high-level approach spans towards the main channel long spans with haunched steel girders providing a 250-foot wide by 135-foot-high navigational channel. The substructure and foundations vary from pile bents to concrete columns and caps on waterline footings, all using prestressed concrete piles. The design approach provided a simple and repetitive structure, which increased construction efficiency, allowing the design and construction to be completed within 24 months.

“Re-evaluation of Bridge Weight Restrictions via Load Rating through Field Load Testing”
Presented by Ed Zhou, PhD, P.E .
Bridge Instrumentation & Evaluation Lead
AECOM
Receive (1.0) PDH
12Noon - 1PM EST
WEBINAR PLATFORM: Zoom
Presentation Topic:
Bridge load ratings measure a bridge’s load carrying capacity for vehicular loads in addition to its self-weight. Engineering experience has indicated that conventional methods usually yield conservative bridge load ratings due to simplifications in the analysis. In many situations, rating calculations based on the conventional analysis method indicate that the bridge needs to be posted for weight limits and yet it still carries heavy vehicles without visible signs of distress. The issue becomes more pronounced for aged or deteriorated structures, or for structures lacking information on material properties or construction plans.
Bridge load rating through nondestructive field load testing is a refined method for bridge load rating and is prescribed in AASHTO’s The Manual for Bridge Evaluation (MBE). The MBE recommends two load testing procedures: diagnostic load test and proof load test. Each method offers its own advantages as appropriate to individual circumstances and can produce more accurate load ratings than the conventional analysis. Key results from a load test are live load effects (strain and defection) at critical locations due to controlled test loads of known weights and positions. Test results quantify actual live load distribution in primary load carrying members such as skewed slabs, multiple beams or trusses including the influence of support conditions. Field measurements also help assess inherent load carrying mechanisms such as unintended composite actions and participation of secondary members.
This presentation discusses field load testing for bridge load rating and weight restriction re-evaluation purposes using both the diagnostic and proof load testing methods with multiple example projects.

12Noon - 1PM EST
WEBINAR PLATFORM: Zoom
Presentation Topic:
Overheight vehicles often collide with highway bridges, causing structural damage, injuries, and sometimes even fatalities. For example, on June 23rd, 2021, a 65-year-old pedestrian bridge over D.C.'s Route 295 collapsed after it was struck by a truck. Much earlier in 1999, a truck hauling an overheight excavator struck and collapsed a pedestrian bridge over the Baltimore Beltway, killing one motorist and injuring three others. This topic is to present the earlier study by Dr. Fu to assess the magnitude of overheight vehicle collisions at both the Maryland and national level after the 1999 Baltimore accident.
Statistics on overheight collisions in Maryland were collected from overheight vehicle detector records, the statewide accident database, and bridge inspection reports. Of the 1496 bridges susceptible to impact by overheight vehicles statewide collected earlier, 309 (20%) have been struck, with 58 (4%) having required repairs. A survey was sent to each state to collect national statistics. Of the 29 states responding, 18 (62%) indicated they consider overheight collisions to be a significant problem.
Also presented associated with this topic are the overheight vehicle detection and bridge collision damages/repairs.

Global VP of Sales - Alchemco
Receive (1.0) PDH
12Noon - 1PM EST
WEBINAR PLATFORM: Zoom
Presentation Topic:
Reinforced concrete is one of the most utilized building materials in the world. But in order for concrete structures to meet or exceed their full design life, they must be properly protected from the weather and other corrosive elements (which are working every day to shorten that lifespan).
Most of the waterproofing options available to architects & engineers, involve materials that are specifically designed to provide only ‘short-term’ protection. While many structures are designed to last at least 50 – 75 years, the materials used to protect those structures from the elements are designed to last a maximum of 5 – 10 years. Thereby, requiring that these protective materials be installed … removed … and reinstalled again; several times during the lifespan of the structure (at great expense to the owners).
The TechCrete 2500 Waterproofing System provides true ‘long-term’ waterproofing protection (for the design life of the structure) after a single application. This spray-applied, integral waterproofing solution has been used to protect important structures around the world for over 40 years … and was voted by the Concrete Industry as ‘2020 - Most Innovative Product’ at the World of Concrete Convention in Las Vegas last February. Please join our upcoming webinar to learn about this state-of-the-art waterproofing technology, and how it can provide you with a cost effective, long-term solution to your concrete waterproofing needs.

12Noon - 1PM EST
WEBINAR PLATFORM: Zoom
Presentation Topic:
Trusses are one of the more common uses of Hollow Structural Sections (HSS). The joints and connections of HSS members in trusses can be the cause of confusion during design and of unneeded costs during fabrication. It is important to understand the various joint configurations and how they relate to the overall strength and stiffness of a truss. Fabrication cost, which is a primary cost of steel structures, can be greatly influenced by the joint and connection design, more so than the overall weight of the truss. The choice of member shapes, the configuration of the joints and choice of weld type has direct impact on the limit states that need to be checked and on the cost of fabrication. This presentation will highlight how to avoid some of the common pitfalls when designing and detailing HSS truss connections and joints. Through some simple rules of thumb, it will be shown that proper sizing of truss members and proper design of truss joints and connections can lead to a much more cost effective and efficient structure.
Learning Objectives:
Identify ways that HSS truss joint configurations relate to the overall strength and stiffness of the truss.
Understand the different limit states that control the design of different joint configurations.
Understand that fabrication cost of an HSS truss is directly related to the design of the truss joints and connections, rather than the overall weight of the truss.
Apply concepts used for planar trusses to the analysis and design of multi-planar trusses

“Sustainable Infrastructure and the Role of Envision”
Presented by Lindsey Geiger, PE, ENV SP, LEED AP BD+C
Director, Education - Institute for Sustainable Infrastructure
Receive (1.0) PDH and (1.0) AIA LU/HSW
12Noon - 1PM EST
Topic Description:
Consider the importance of infrastructure in our daily lives. Infrastructure provides the basis for public health, impacts the economic viability of our communities, moves people and goods, and creates spaces for us to enjoy. However, despite the need for infrastructure and the many benefits it provides, historically it is overlooked and underfunded until it breaks down or service is disrupted.
Decades of neglect mean that massive investments in infrastructure are now needed. Aging and outdated infrastructure needs to be replaced and modernized. At the same time, population growth and climate change are stressing financial, material, and technological resources. Infrastructure is at the heart of addressing key challenges of the 21st century, and the standards and methods of the past will not be adequate to meet the needs of the future. A new paradigm is required.
How do you know whether your decisions as engineers and architects are contributing to sustainability or not? How do you bring attention to the need for more sustainable infrastructure? How do you communicate around a shared understanding of what sustainability means?
This presentation introduces Envision as a framework for providing the guidance needed to initiate systemic change in the planning, design and delivery of sustainable and resilient infrastructure. Envision:
Sets the standard for what constitutes sustainable infrastructure;
Incentivizes higher performance goals beyond minimum requirements;
Gives recognition to projects that make significant contributions to sustainability; and
Provides a common language for collaboration and clear communication both internally and externally.

“Top Things You Should Know About HSS Connections”
Presented by Brad Fletcher, S.E.
Senior Sales Engineer - Atlas Tube
Receive (1.0) PDH and (1.0) AIA LU/HSW
Dinner Buffet and Open Bar
Topic Description:
Hollow structural steel (HSS) member connections often seem mysterious — but they don’t have to. While not a how-to guide, this presentation highlights aspects of HSS connection design that are often overlooked or misunderstood. Attendees will gain a clear understanding of tension, shear, moment and truss connections and how they differ from other types of connections.
HSS connections share multiple limit states with other types of connections, however, for HSS there are usually additional limit states that need to be checked. This often leads to confusion and misunderstanding of these types of connections.
This presentation will cover some frequently asked questions about the design of different types of HSS connections, including both bolted and welded, for tension/compression, shear and moments.
Understanding the HSS specific limit states and how they directly influence the connections can lead to more economical and cost effective connections. Too often, misunderstanding these limits states produces to poor connection design or the need to reinforce connections after fabrication.

“Temporary Support of Excavation and Underpinning Systems”
Presented by Steve W. Fung, P.E.
Senior Vice President - Schnabel Engineering
and
George Aristorenas, PhD, P.E.
Principal - Schnabel Engineering
Receive (1.0) PDH and (1.0) AIA LU/HSW
Dinner Buffet and Open Bar
Topic Description:
As more and more projects are constructed in high-density developed areas, the use of temporary support of excavation and underpinning structures are often required to mitigate the risk of damage to adjacent structures from the new construction. Underpinning systems are typically designed by the owner’s designer and the contractor’s role is to install the system as designed. The design of temporary support of excavation (SOE) systems are typically left to the contractor; thus, the contractor assumes the risks associated with both the design and performance of the system.
The owner’s designers typically perform a subsurface investigation that is solely focused on providing subsurface information for the design of the permanent structures, and little or no thought is given to subsurface information needed to properly design the temporary SOE system, or the constructability of the system. The design of temporary SOE could be a high risk and costly endeavor.
This presentation provides an overview of temporary support of excavation and underpinning systems, and discusses the following topics:
Subsurface investigation and engineering properties needed to properly design a temporary SOE system.
Types of temporary SOE systems and constructability issues related to the different types.
Types of underpinning systems and constructability issues related to the different types
Effect of groundwater on the design and performance of temporary SOEs
Failure modes of temporary SOEs

“Condition and Deterioration Assessment of Bridge Elements Using Advanced Digital Imaging Technologies”
Presented by Ed Zhou, PhD, P.E.
Bridge Instrumentation & Evaluation Lead, North America - AECOM
Topic Description:
Concrete elements of steel or concrete bridges, such as piers, slabs, or girders, may exhibit various signs of surface distress or deterioration, most noticeably, cracks. Accurate mapping and monitoring of existing cracks is important to bridge deterioration modeling because some cracks may grow due to the effects of loads and environment but others may remain unchanged over time. The current practice of mapping concrete cracks is primarily manual, making accurate identification of crack growths difficult. The manual records are generally subjective and practically impossible to be complete and accurate. The required field operations can be time consuming and often cause traffic disruptions. Recent advancements in digital imaging technologies, including equipment hardware and image processing techniques, make mapping of concrete cracks more objective, more complete and more accurate. The use of unmanned aircraft systems (UAS), or drones, makes field data collection more productive and less disruptive to traffic. This presentation discusses application of UAS for mapping existing concrete cracks on bridge elements. Topics include field data collection, photogrammetric 3D modeling, orthographic imagery, digital image processing for crack identification, as well as temporal subtraction for deterioration assessment

Director of Engineering Solutions – Fyfe Co. LLC
**Receive 1.0 Professional Development Hours**
Topic Description:
Over the last twenty-five years, the use of fiber reinforced polymers (FRP) materials has gained more popularity. Unfortunately, many designers do not have a fundamental understanding of the structural testing results that have led to the existing design guidelines being adopted (e.g. ACI 440.2R-17). Before a designer proceeds with the various design procedures, it is critical that they first understand the fundamental material behavior and specifically how these advanced composites work with the existing reinforced concrete sections. This presentation will review several structural tests spanning from the 1990's to present day and will highlight the detailing that is not addressed by the current codes and guidelines.

Research conducted at the Carnegie Institute of Technology (aka the Carnegie Mellon College of Engineering) has suggested that only 15% of your financial success is due to your technical expertise. The other 85% is due to your skills in human engineering, i.e. your personality and your ability to deal with people. And as strategic use of economic power translates into influence and recognition, perhaps a closer look at the need for an education involving human engineering is in order.
It is a fact that a structural engineering education is focused almost exclusively on technical topics with practically no exposure to human engineering. Could that be the reason why the professional fees and compensation for structural engineers do not even begin to reflect the profession's immeasurable contributions to humanity? And why our profession is not even in the running for any high profile recognition or prize, such as a Nobel?
In this talk, Ashraf emphasizes the need for a human engineering based education. He convincingly demonstrates, with his usual enthusiasm and humor, why it is important to cultivate deep personal beliefs, to develop public speaking skills and to become familiar with the arts, human psychology and human chemistry. These talents will enable young engineers to enter the professional world ready to lead, influence and inspire!

"Bridge Instrumentation/Testing/Monitoring for Maintenance and Preservation Decision Support"
Presented by Ed Zhou, PhD, PE
AECOM Bridge Instrumentation & Evaluation Lead, North America
**Receive 1.0 Professional Development Hours**
Topic Description
Bridge instrumentation and field testing/monitoring involves various types of sensing and data collection technologies, non-destructive testing/evaluation (NDT/E) techniques, as well as structural testing/monitoring methods. If planned and implemented properly, field instrumentation can provide information on bridge in-situ conditions and actual responses to specific loads, which would not be known otherwise. Applications of bridge instrumentation and field testing/monitoring include bridge load rating, fatigue life assessment, condition and defect assessment, problem diagnosis, and various types of structural performance evaluation. The ultimate goal is to support engineers and bridge owners for better decisions in bridge maintenance, weight restrictions, preservation, and replacement.
This presentation will discuss several bridge instrumentation and field testing/monitoring methods through example projects. The methods will include diagnostic and proof load testing for bridge load rating, field measurement of stress range histograms for fatigue life assessment, the taut cable vibration measurement (TCVM) method for assessing existing tension in cables or P-T bars, and investigation of signs of distress for effective repair methods. The discussions will address instrumentation plans, data collection and processing methods, testing/monitoring results analysis, comparison with and calibration of analytical models, and finally and most importantly, decision support in bridge maintenance and preservation.

"Quality in the Constructed Project: A Guide for Owners, Designers, and Constructors, ASCE, Manual of Practice 73"
Presented by Michael O'Connor, PE, M.ASCE
Vice-President & Chief EngineerFrederick and Pennsylvania Line Railroad Museum Mix
**Receive 1.0 Professional Development Hours**
Topic Description
The purpose of ASCE Engineering Practice for Quality in the Constructed Project is to provide project owners, design professionals, and constructors with information and recommendations on opportunities to enhance the quality of constructed projects as well as factors that drive project quality. In its manual on CE practice for delivering quality, ASCE states its guide was not a technical standard, nor a compilation of standard industry practices. The striking feature of the MOP is that unlike the ISO quality frameworks, ASCE's quality vision places the civil engineer on par with the owner and contractor as "customers" in the project execution and delivery. No reference is made to either stakeholder or process in this definition. There are other comparisons to Project Management Institute and ISO, the speaker will discuss these topics.

"Business Ethics vs. Engineering Ethics: Conflicts of Interest, and Unlicensed & Unauthorized Practice"
Presented by Troy S. Brown, Esq
Enforcement Division of the U.S. Securities and Exchange Commission
**Receive 1.0 Professional Development Hours**
Topic Description
The concept of “business ethics,” as economist Milton Friedman summarizes, is “generally … to make as much money as possible while conforming to their basic rules of the society, both those embodied in law and those embodied in ethical custom.” Conversely, the concept “professional ethics” are often established by professional organizations to help guide members in performing their job functions according to sound and consistent principles, adopted by that professional community. Being caught between the proverbial Scylla of business ethics and the Charybdis of professional ethics can be difficult for engineering professionals to navigate. Many potential problems can arise for those aspiring endeavoring to build a lucrative business, especially one involving professional services that may be considered quasi-engineering, in nature.
This presentation focuses on the interaction and tensions between professional ethics and business ethics, namely business conflicts of interest, unlicensed practice, and unauthorized practice. These issues necessitate resolving essential questions; the failure to properly navigate the interstices of business and professional ethics could result in reprimand, suspension, fines, revocation of one’s professional license, ruinous liability or the inability to compete, and, in the case of engineering disaster, even death. Many questions arise while balancing between these often opposing ethical poles. For example, what concerns should an engineer consider before being engaged to perform similar services for rival businesses? For a businessperson providing quasi-engineering services, should it matter, from an ethical perspective, if unlicensed an “engineer” provides engineering services? Similarly, should there by any ethical issues if an engineer licensed in one state extends her business into another state without obtaining proper authorization?
From one perspective, we as a society want to protect the justified and reasonable endeavors of qualified professionals. One the other hand, society has an interest in ensuring minimum safety requirements for services provided by engineers. Sometimes these tensions can be harmonized, but as the provision of services becomes a matter of interstate commerce, these tensions become rather difficult to resolve. These issues, while not exhaustive of their type, represent three of the more ubiquitous and challenging for the 21st century professional/businessperson. The presentation will use several scenarios to illustrate the tensions between the contrasting concepts of professional ethics and business ethics to facilitate discussion.

**Receive 1.0 Professional Development Hours**
Topic Description
Ultra-high performance concrete (UHPC) is one of the major breakthroughs in concrete technology in the last two centuries. It is a fiber-reinforced, cementitious material that offers exceptional mechanical and durability performance, including compressive strengths exceeding 22,000 psi and excellent resistance against environmental degradation. For this reason, UHPC is being considered for a wide variety of structural and architectural applications to provide innovative design solutions. The Federal Highway Administration (FHWA) has taken significant interest in this material as part of their Every Day Counts program to promote accelerated bridge construction (ABC) through the use of prefabricated bridge elements. Field-cast UHPC is used in this case to join prefabricated elements on-site to form simple, strong, durable connections for improved long-term performance. Over 180 bridges throughout North America have been constructed using this type of system. This presentation will discuss what UHPC is, what characteristics it exhibits, the advantages to using it, and the various structural applications that have proven successful over the years.

"Bridge Foundations: Constructability Issues In The Design And Selection Process"
Presented by Steve W. Fung, PE
Schnabel Engineering, LLC.
**Receive 1.0 Professional Development Hours**
Topic Description
Bridge foundations are designed based on the AASHTO LRFD Design Specifications, 7th Edition, 2014. The specifications provide design guidelines for the design of different foundation elements, however, the selection of the appropriate foundation type for support of the bridge structure is ultimately the responsibility of the designer. The selection of the appropriate foundation type is typically based on one or more of the following factors:
•The magnitude and type of foundation loads.
•The subsurface conditions at the site
•Cost of the foundation type
•Special design considerations such as scour and downdrag loads
•Availability of technology and local practice
•Constructability
For designers to fully incorporate constructability into their design, the designers must have a thorough knowledge of the construction process; experience in the construction planning process and field operations; and knowledge of the available technology and resources, to achieve the overall project objectives. Most designers do not have this level of knowledge, therefore, while constructability is already practiced to some extent by designers, some aspects of constructability is sometimes overlooked in the design and selection process of foundations – which could lead to project delays, cost overruns, or even litigation.
This presentation provides an overview of some of the constructability issues related to different foundation types, and discusses some of the constructability issues that the designer should evaluate when selecting foundations in the following environments:
•Urban fill
•Soft compressible soils
•Lateral resistance
•Available space/Site constraints
•Karst/Sinkholes
•Scour
•Depth to rock
