The demonstration will show the ins and outs of Sika's FRP installation process with the multiple system options Sika offers to help with your needs for a proper install on site.
Demonstration will show how to apply solvent-based concrete sealers and discuss the various considerations to keep in mind, tools you will need, how to prepare your surface area, ideal environmental conditions for use of the sealers, the step-by-step application process, and how to safely clean up the area following application.
The demonstration will show the application of the Black Pearl® Waterproofing System. Unlike “weatherproofing”, a true waterproofing membrane will maintain its watertight integrity and prevent the passage of liquid under dynamic, static, continuous, or intermittent hydrostatic pressure. Black Pearl® is a true waterproofing membrane composed of two primary products: Black Pearl® Primer Adhesive and Black Pearl® Waterproofing Membrane. These components are based upon the same core formula of select, unoxidized asphalt cement base, butyl rubber, SIS, neoprene rubber, SBS, carbon black, fillers, plasticizers and curing agents. The Black Pearl® Primer Adhesive also has an aliphatic solvent that is within acceptable OSHA and EPA current regulations. Black Pearl® Waterproofing Membrane is a 55-mil woven polyester fabric impregnated with the Black Pearl® rubberized formula, providing extra tensile strength and stability.
This demonstration will introduce the WJE CASLE™ (Corrosion Assessment Service Life Evaluation) software for predicting corrosion-related damage in reinforced concrete structures. This tool helps engineers more effectively quantify remaining service life and guide repair decisions for existing structures, as well as evaluate protection/durability design strategies for new structures. Developed in-house by WJE’s materials engineers for WJE structural assessment projects, WJE CASLE™ offers full control of the evaluation process and facilitates a customizable approach to construction parameters and exposure conditions unique to each project. Advantages of the software include consideration of site-specific conditions such as construction geometry, sealers, coatings, corrosion-resistant reinforcing, presence/installation of overlays, existing chloride profiles, concrete cracking, and two-sided exposure. Model features will be outlined with a focus on evaluation of existing structures.
This demonstration will highlight the successful renovation of a concrete floor at the Flatstick Pub in downtown Spokane, Washington. The application of a self-levelling, polishable cementitious topping will be shown and the benefits of topping versus complete tear-out of the floor will be described.
The general sentiment around construction and modern technology is that the industry has been slow to embrace it. While this is true of the past, the current and future construction industry is all about modern technology. Not only does technology help to make the industry safer (something that has been a struggle for a very long time), but it is helping contractors to take back control of their budgets, to make smarter choices about project planning and equipment and is, consequently, pushing the green-construction trend forward. The purpose of this presentation is to provide a summary on the current technologies being used in the construction industry with a focus on concrete and to dig even further as to how these can be applied to repair projects. It will provide case studies on how using technology to bring ambient and concrete temperature, relative humidity and strength (among other) data online can help contractors be more efficient.
The prestressed beams in the Hampton Roads Bridge Tunnel Approach Spans were fabricated in about 1960 (west bound lane) and 1970 (east bound lane). The spans are 50-ft and 75-ft, respectively. The brackish water environment caused corrosion and failure of the bottom strands and deterioration and spalling of the cover concrete in many beams. A project in 2018 strengthened 30 of the more deteriorated beams as an alternative to posting or replacing the bridges. Carbon fiber composite wrap (CFCW) and external post-tensioning (PT) were used to strengthen the beams. Prior to construction, a PT mockup was done with one 50-ft (flexible filler) and one 75-ft (grout) beam to demonstrate that the contractor had the materials, equipment and staff to successfully do the external PT. This presentation describes the project’s mockups and construction and the anticipated increase in strength to be obtained from application of the CFCW and external PT.
We will provide a brief presentation on the AET team, the AET services and business, how we operate as a team and perform our testing services, and what benefits we can provide our customers. We strive to get to know our clients well, educate them, and provide innovative, multi-disciplinary, and personalized service.
Technology is not limited to innovative materials or equipment on a jobsite. Digital technology is changing how teams operate and is dramatically increasing efficiency and effectiveness. Cloud-based project management software allows key stakeholders to consolidate project data on to one mobile platform for easy collaboration. The entire project team, from general contractors, specialty contractors, owners, architects, engineers, conservators, and others can exchange data and documents with the tap of a screen. Communication between the field and the office is streamlined where everyone has access to real-time project details. This helps avoid duplicate entry errors and rework because teams built from an outdated drawing. In addition to drawings and details, project management software brings contracts, submittals, RFIs, billings, safety reporting, meeting minutes, photos, and financial reporting into one platform.
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.
