The application of nondestructive testing and evaluation for detecting existing defects and anomalies in concrete structures will be presented. Proper inspection and assessment is an integral part of a successful repair and rehabilitation. A well-defined inspection will help asset owners and their consultants in identifying the location and extent of existing defects, and enabling them in selecting proper repair materials and optimizing the area that needs rehabilitation. Moreover, NDT methods can help identify potential defects that are not visible to the naked eye, such as early-stage delamination, corrosion, and other durability related issues. In this presentation, several cases in Canada will be demonstrated, where the results of nondestructive testing and evaluation have been used to help consultants and contractors with cost-effective and reliable repair planning. Applications of ground penetrating radar, ultrasonic pulse echo tomography, seismic tomography, will be discussed.
This demonstration shows Sika's new one coat traffic coating systems. Sikalastic®-720 One Shot is a two-component, integral texture, fast-curing, aliphatic, elastomeric polyurethane waterproofing coating intended for vehicular and pedestrian traffic. Applied in a single step, Sikalastic®-720 One Shot replaces the need for a base coat and multiple topcoats. Sikalastic®-726 Balcony One Shot is a two-component, aliphatic, elastomeric polyurethane traffic coating system that has both superior flexibility and abrasion resistance. Easily applied in a single coat, with or without primer, and designed for pedestrian traffic, specifically balcony and pedestrian applications.
Moisture accumulation and water leakage into retail, commercial, and residential habitable spaces, including industrial facilities and below-grade parking structures, is the number one construction defect claim in our industry. The entire building envelope is a moisture barrier. Below-grade moisture barriers are required to keep water from leaking “into” and/or “out from” the structure. Water leakage inflow or outflow, and moisture accumulation within, can lead to health, safety and environmental issues involving the cost of operations and facility maintenance. Active water leakage, intermittent wetness, cavity wall moisture accumulation, and vapor transmission, can lead to costly problems: mold and mildew development, corrosion, contaminated water clean-up and disposal, slippery surfaces, and property damage.
Demonstration will present the Aquajet product line of equipment and hydrodemolition work up close. We will feature the Aqua Cutter robot, the Ecosilence high-pressure pump system, and the Ecoclear water treatment plant. We will also demonstrate the advancements in hydrodemolition equipment and problems solved for contractors.
Demonstration will show Schönox AP Rapid Plus poured over Schönox Renotex® 3D Glass Fiber Reinforcement fabric that makes up our Renotex® 3D Renovation System. It is designed to create a new substrate for subsequent floor covering installation. Schönox AP Rapid Plus is a pumpable self-leveling compound designed for deep pour, fast-track installations on most substrates in interior areas. It is built with Hybrid Active-Dry Technology, which means that ambient air temperature and humidity have no effect on curing times. This technology is the culmination of Schönox’s extensive research in this area to develop products with fast strength and drying characteristics with minimal shrinkage or expansion. Combined, the Schönox Renotex® 3D System is strong, versatile, and durable.
Using Unmanned Aerial Vehicles and Systems (aka UAVs aka Drones) continues to be a hot topic for engineers and designers. Within the past 10 years, we have seen technology change how we live, work, play and learn. These advances in technology have enabled humans to be more efficient as well as socially and environmentally conscious and connected. Advances in engineering technology and efficiency have expanded structural engineer’s roles in inspection services. This presentation will highlight drone utilization for exterior surveys and inspection, impact on the built environment, and how drones will continue to influence in the future. This includes areas that are too dangerous for humans or structures where rigging can be difficult or impossible as well as the cost benefits of using a drone. The presentation will also delve into the effectiveness and appropriate applications of drone usage, specifically for hands-on applications.
Join us for an exciting hour showcasing new initiatives of ICRI; innovations at the chapter level; and a high energy panel discussion exploring lessons from the pandemic that are re-shaping our industry.
Richard Miller Treatment Plant is a 240 mgd cap. potable water treatment facility located in the California area of the Cincinnati, Ohio, US. After installing an advanced ultraviolet (UV) disinfection treatment system in 2013, GCWW became the largest water utility in North America to use UV light following sand filtration and granular activated carbon. The concrete filter gallery building was originally constructed in 1907 with 26 filters, with a 14-filter addition in 1937 and 7 filters added in 1964. After over 110 years of service, the structures started showing significant signs of deterioration, most commonly concrete spalling and reinforcing steel corrosion. This case study will highlight the methods used to evaluate the structures that involved conventional methods such as sounding, crack mapping, chemical and petrographic examinations, along with technology such as Half-Cell Potential/ICOR, Impact-Echo, Ground Penetrating Radar, and UAS (Drone) services.
On August 9, 2019, Tyson Foods' Holcomb, Kansas beef plant experienced the first large fire in the meat processing industry in nearly 20 years. The long-burning fire precipitated the collapse of a portion of the high roof over the mechanical mezzanine, which housed equipment for numerous critical plant processes. This took portions of the plant, the second largest in the United States, out of operation for months. The pressures of substantial business interruption costs, as well as the market consequences for cattle feeders from the Southern Plains region, necessitated a rapid response. This presentation highlights the investigation into the extent of damage to precast members, including visual inspection, nondestructive and laboratory evaluations, testing, simulation, and analyses. Based on this investigation, members were identified for repair or removal and replacement.
