What is a 'Severe Environment'?
David Tepke, SKA Consulting Engineers, Inc.

0.5 LU AIA CES Approved (live only)
0.5 PDH (both live and on-demand)

Description: Repairing and extending the service life of concrete in severe environments first requires that one understands what may be considered severe why it may be considered so. This presentation will discuss the ways in which different organizations and technical committees around the world define ‘severe environments’ for concrete structures; types of deterioration mechanisms and materials-related distress that may severely and quickly deteriorate concrete, type of structures with potentially severe environments, and U.S. geographical considerations. Although the focus of the presentation will be on the definition of ‘severe’ and the types of issues that make a particular condition severe, the presentation will also discuss repair strategies that may be used to for addressing the described issues. Distress mechanisms such as corrosion, sulfate attack, ASR, freezing and thawing distress and fire will be discussed, as they pertain to manufacturing and processing, infrastructure (water, energy, transportation), parking, transportation, coastal and other structures. The primary goal is that the audience will be able to use the presentation for a basis of understanding of ‘severe’ in development of repair strategies for these structures

Learnig Objectives:

  1. Identify general types of deterioration mechanisms in concrete that may hasten deterioration of concrete structures, leading to a ‘severe environment.'
  2. Determine if a structure is susceptible to being in a ‘severe environment’ based on type and geographical location in the United States.

The Truth about the OSHA/ANSI Fall Protection Standards
James Boatright and Scott Weiland, Innovative Engineering, Inc.

0.5 LU AIA CES Approved (live only)
0.5 PDH (both live and on-demand)

Description: Falls are among the most common causes of serious work-related injuries and deaths. OSHA estimates that, on average, approximately 202,066 serious (lost-workday) injuries and 345 fatalities occur annually among industry workers. To reduce these statistics, OSHA issued a final ruling on the General Industry Rules 29 CFR 1910, Subpart D, Walking-Working Surfaces update on November 17, 2016. This update includes fall protection requirements for low slope roofs, façade access, and ladders as well as a timeline for compliance. This seminar not only addresses the recent 2017 updates to 29 CFR Part 1910 General Industry, but is an overview of all fall protection standards found in both Part 1910 for General Industry and Part 1926 Construction. The components of a Comprehensive Managed Fall Protection Program are also presented as well as specific requirements for the fall protection options available. Because many in the industry either do not understand the standards, are unaware of the available OSHA interpretations, or prefer not to spend money training their employees, misinformation is being spread. This seminar provides the truth about the required implementation of the updated fall protection standards and the standards that remain in place.

Learning Objectives:

Alkali-Silica Reaction: Cause, Effects, Mitigation, and Repair
Farhad Habibi and Justin Breg, Caskanette Udall Consulting Engineer

0.5 LU AIA CES Approved (live only)
0.5 PDH (both live and on-demand)

Description: Alkali-Silica Reaction (ASR) can cause significant damage to concrete structures including bridges, roadways, airport runways, and nuclear power plants. When reactive aggregates are included in a mix, the presence of moisture initiates a reaction between the alkaline cement paste and reactive amorphous silica. The result is a gel that continues to dilate, which may cause cracks in the concrete mass.

A research program was undertaken at the University of Toronto with the sponsorship of the Canadian Nuclear Safety Commission (CNSC) to investigate the effects of ASR on large-scale and small-scale concrete specimens. Several specimens were constructed using reactive (ASR) concrete and non-reactive (regular) concrete, and their short-term and long-term structural and mechanical behaviour were compared. To accel¬erate the deterioration of concrete, wall specimens were stored in an environmental chamber, specially constructed with the capacity to store large specimens in controlled high-temperature and high-humidity conditions.

In this presentation, we will discuss the results of the research program, will offer best practices to minimize the risk of ASR in concrete during placement, and will propose several strategies for repair of structures that have been degraded due to ASR.

Learning Objectives:

  1. to understand the cause of ASR
  2. to understand the effects of ASR on concrete properties and durability
  3. to learn best practices for minimizing risk of ASR
  4. to become familiar with strategies for remediating structures affected by ASR

Rehabilitation of the Ituango Dam
Robert Cordova and Richard First, Master Builders Solutions

0.5 LU AIA CES Approved (live only)
0.5 PDH (both live and on-demand)

Description: The Ituango dam is an embankment dam that is currently under construction on the Cauca River near Ituango in Colombia. The largest hydroelectric power plant in Colombia’s history, the dam measures 720 ft (220 m) tall, will produce 2.4 giga watts and will produce approximately 13% of Colombia’s energy.

Three, large diversion tunnels used to divert the water from the river around the construction site during construction collapsed as a result of heavy rainfalls. The nearly completed pump house had to be flooded to accommodate premature water build-up in the reservoir. These tunnels would need to be permanently sealed.

“Pre-stoppers” would need to be constructed in place to serve as bulk heads between which would ultimately be excavated and back-filled with concrete to permanently seal the tunnels. Additional to standard anti-washout properties, the grout had to withstand swiftly flowing water and exhibit an extended working time at temperatures above 32 degrees C. A custom grout was developed for this application. In the end, hundreds of grout micropiles were tremied, consuming more than 1,650 tons of grout, to produce the pre-stoppers to complete the remediation. The dam is currently scheduled for completion in 2023.

Learning Objectives:

  1. What is the Ituango Dam
  2. Why it was built
  3. What went wrong

Dallas City Hall Plaza Parking Garage – Repair of Bonded Post-Tensioned Slab System
Stephen Lucy, JQ Engineering, LLP

0.5 LU AIA CES Approved (live only)
0.5 PDH (both live and on-demand)

Description: Dallas City Hall and Plaza are recognized by many due to the opening scenes of Dallas, the television show. What is less known is that the structure is a significant early example of bonded post-tensioned concrete which was utilized throughout the superstructure and two-story parking garage constructed beneath the plaza. Opened in 1977, the parking garage is a two-way bonded post-tensioned concrete slab with unreinforced drop panels supported by flared circular concrete columns. The garage covers two city blocks, extends under two adjacent multi-lane streets, and supports mature landscaping, pool, fountain, and up to 11’-0” of soil. In 2017, several square feet of a drop panel fell from the structure and subsequent observations found multiple locations of drop panel and column capital failures. A structural investigation including destructive and non-destructive testing, and analysis of the existing structure was undertaken to determine the cause of the failures. Structural repairs were then developed to address the failures as well as the root cause of the failures. Constructability and value engineering reviews were incorporated into the process to maximize benefit while reducing risk and costs.

Learning Objectives:

  1. Attendees will learn of about early bonded post-tensioned systems and lessons learned regarding the design and construction of these systems
  2. Attendees will learn of new design and data acquisition tools available to the design professional.
  3. Attendees will learn to creatively and thoughtfully evaluate the use of technology and material advances and how to blend these advances with proven practical approaches.
  4. Attendees will learn the importance of constructability reviews and value engineering which maintains quality while reducing risk and costs.

Extreme Environments Require a Versatile Repair Mortar
Andrew Fulkerson, MAPEI Corporation

Description: The demonstration will cover the use of MAPEI’s high alkaline corrosion inhibitor, Mapefer 1K and encapsulation of the repair area with Planitop 12 SR. Planitop 12 SR is a versatile, sulfate resistant, fiber-reinforced, with silica fume and corrosion inhibitor that can be applied by hand, pump, or spray on horizontal and vertical surfaces. Demonstration will show how to utilize these products in accordance with ACI Repair Application Procedures (RAP) 3, 6, and 7 as well as ICRI Guideline Nos. 310.1R and 310.2R. Demonstration will showcase a project where Planitop 12 SR was recently used to repair a Wastewater Treatment Tank.

Objectives:

  1. Show repair scenario of ACI RAP 3, 6, and 7
  2. Educate on use of corrosion inhibitor over properly cleaned steel
  3. Educate placement techniques for horizontal and vertical applications
  4. Show difference between pumping and spraying mortar

Tools and Techniques for Efficient Sealant Joint Preparation, Installation and Finishing
Bob Reynolds, Albion Engineering Company

Description: Selection of the most appropriate, professional tools for the setting of foam backer rod at the correct, consistent depth, without puncturing the skin, is the first step in creating a sealant joint that is long lasting and meets sealant manufacturer specifications. Next is the selection of the optimal sealant dispenser and nozzle. The size and orientation of the joint and the viscosity of the specified sealant will guide an installer to the most efficient drive, material containment unit (MCU) and nozzle for the application. Lastly, the selection of the most appropriate caulk finishing spatula and the technique employed are critical for the sealant to adhere and perform to specification.

Objectives:

  1. How to assess a sealant joint for joint filling
  2. Dispensing tool selection
  3. Dispensing techniques
  4. Wet sealant tooling / finishing for adhesion

The Tower Heist: Planning a Successful High-Rise Slab Edge Repair
Ali Abu-Yosef and Michael Ahern, Pivot Engineers, PLLC

0.5 LU AIA CES Approved (live only)
0.5 PDH (both live and on-demand)

Description: After only six years of service, a 6-foot long narrow piece of concrete spalled off an exposed slab edge of a 680-foot tall high-rise in Texas, and fell 160 feet to the podium below. The spall was attributed to premature corrosion at the drip edge. The building featured approximately 9,200 feet of exposed slab edge over its height. Given the potential risk to safety and property of additional concrete spalls, the Owner requested forensic investigations, which (1) identified other areas with signs of similar distress and (2) determined the underlying problem of low reinforcement cover at the drip edge was pervasive. In response, repair options were developed to address the problem and restore intended durability. Given the building height, difficult exterior-only access, downtown environment, and post-tensioning anchors along the slab edge, the repair design and construction both had unique challenges to consider and overcome. The engineer and contractor worked collaboratively on nearly all aspects of the project to develop effective and constructible repairs for the slab edges. The repairs consisted of structural replacement of the slab edges with GFRP reinforcement and new waterproof coating, which were completed in summer 2019 after approximately 16 months of construction.

Learning Objectives:

  1. the underlying problem that required repair,
  2. repair design challenges,
  3. repair construction challenges, and
  4. importance of collaboration to avoid and address field challenges.
