- Arlington Memorial Bridge is a reinforced concrete spandrel arch bridge that connects Washington, DC and Virginia across the Potomac River. After over 85 years in service, the bridge started exhibiting signs of deterioration, including reinforcement corrosion. As part of a major rehabilitation effort to extend the bridge’s service life, targeted cathodic protection (CP) systems were installed in the arch cross-walls, floors, and under arches to mitigate and prevent corrosion. The implemented CP system consisted of galvanic and two-stage anodes to mitigate corrosion. Galvanic anodes were installed in the repair areas to prevent the ring anode affect and ensure a durable concrete repair. The two-stage anodes were installed in areas of concrete which were actively corroding without signs of concrete deterioration.

- Historic 19th and 20th century buildings are currently facing the necessity of meeting contemporary needs such as adaptive re-use, energy efficiency, stability, and durability. The characteristics of architecture of these periods (i.e., material, design, details, maintenance, and functionality) increasingly make it challenging to maintain authenticity while incorporating new uses. Various strategies of technical interventions can be employed to achieve good results. This presentation will cover the case study of abandoned historic hospital pavilions from the early 20th century which are being converted into a high-end residential complex. The buildings face multiple challenges related to adaptive re-use, as they will be restored and connected with new infills and a glass connector and capped with re-creation of the historic cornices.

- This presentation looks at buildings that are new or being rehabilitated and the impact on making buildings more energy efficient. Starting with the 2012 IBC, and specifically the 2012 IECC portion of the building code and newer versions, the presentation will look at three aspects of the building envelope: Water Resistance, Air Leakage, and Moisture Transmission. It will then compare to identical buildings, the first built in 2000 and the second constructed in 2020. Illustrations and calculations will show how controlling air leakage can have an enormous impact on the service life of the structure, initial cost of construction, and on-going operations. Lastly, the presentation will look at how incorporating simple additions during the repair/rehabilitation process can have a positive impact on the environment as well as the building owner and the building’s constituents.

- he appeal of a post-pandemic return to normalcy is undeniable. Everyone is ready to leave the days of mask wearing and Zoom meetings behind and to return to the days of water cooler gatherings and all-staff meetings. However, even as we (hopefully) move past the pandemic, it is critical for companies to not lose sight of what they accomplished despite the pandemic. Companies across the world innovated more in one year than they had in the previous twenty years to keep business alive. The question we must now address is: how do we maintain those initiatives and innovative ways of working that allowed us to succeed throughout COVID-19 despite the temptation to return to “business as usual”? In this session, Dr. Hataway will provide essential strategies to help you and your company grow your competitive edge in a post-pandemic world.

- The mitigation of moisture in concrete floor slabs has become an entire sub-industry to the placement of concrete floor slabs that will receive a moisture-sensitive floor covering or coating. In this webinar, attendees will learn what approaches are being used to mitigate an unacceptably high level of moisture in a concrete floor slab and what pre-installation evaluation procedures are necessary to help ensure the success of a moisture mitigation strategy.

- Codes and standards are developed for use by design professionals; however, the use of codes and standards significantly impacts Owners and Contractors. The ACI 562 code was motivated by the poor performance of repaired concrete structures, specifically premature failure of repairs and limited durability of repaired structures. Development of the code was intended to benefit owners and contractors by improving performance and perceptions regarding repairs to existing structures.
