Short Description:
The Avalon Mall parking facility is a four level above grade structure, consisting of three suspended parking levels (approximately 7,750sq.m. each) and one on-grade parking level connected to the existing mall with a new pedestrian bridge. RJC was the structural engineer of record. During construction of the parking structure extensive cracking of the suspended parking garage slabs was noted at two of the 24 pours. RJC undertook a visual assessment of the parking slabs in question to determine the extent of the noted cracking and determined over 750lin.m. of cracks ranging in size from 0.5mm to 6.5mm in width. Following the visual assessment destructive testing of the concrete was undertaken to determine its in-situ properties as well as to understand the full extent of the cracking.

Short Description:
A follow-on presentation to the discussion of our evaluation of over 1500 tire and lube facilities across the United States that prescribed immediate repairs where necessary, reinforcement where deterioration reduced capacity below acceptable levels and coatings necessary to protect structural steel and structural concrete (i.e. our 2019 Philadelphia presentation). This will be an in-depth presentation of how repairs were specified for (3) specific types of structures. The (3) structure types are exposed structural concrete, composite metal deck and fully reinforced form deck slabs all supported by steel structures and reinforced concrete walls. Presentation will include before, during and completion photos of each project discussed. Again, touch on the evaluation processes to include demand to capacity ratios review, evaluation system and inspection form, triggers to determine when shoring is necessary, calculation of capacities per AISC 360, ACI 318, ACI 562 and local building codes.

Short Description:
Two projects will be explored in this presentation. The first is a concrete structure which for 20 years was exposed to extreme heat. The second is a structure which was exposed to extreme vibrations. Both these structures were integral parts of manufacturing processes and required limited down time to repair. The questions needing to be answered were: what is the condition of the existing concrete and what are the repair options for these structures. We turned to non-destructive techniques to evaluate these structures. Non-destructive techniques can provide insight into structures when accompanied by experienced engineers and petrographic analysis. Repair options were provided at the end of our evaluation leading to reduced down time and well-planned repairs.

Short 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.

Short Description:
The FRCM externally bonded Composite Strengthening Systems repair and reinforcement solution combines high-performance sprayable mortar with a carbon-fiber grid that creates a thin structural layer without significantly increasing the structure's weight or volume. With FRCM, contractors can effectively repair, protect, and strengthen concrete and masonry structures in a single application for a fraction of the installed cost of traditional shotcrete.

Short Description:
This demonstration will show FastPatch DPR, an easy to install, long-lasting repair material for distressed pavement that can be applied in warm or cooler climates. It can be used with FastPatch Kicker (accelerator) to form a fast-curing permanent repair that is ready for traffic in a short period of time. DPR has excellent adhesion, absorbs impact and is freeze-thaw resistant. It can easily create smooth transitions and ultra-tough level surfaces. Its minimal site preparation and fast cure times reduce traffic interruptions. The product is completely odorless making it also suitable for indoor applications.

Short Description:
The presentation, through case studies, talks about emergency response services for structural issues encountered during construction of new design projects. Among other examples is an eleven story precast parking structure. The contractor observed significant diagonal faulted cracking of L-beams (supporting double-tee sections) near bearing locations, few days after pouring topping slab. In addition, inverted-tee girders were observed to be supported on cracked corbels at other locations. A quick turn around was required to mitigate any immediate life safety hazard posed by the structural distresses and buy time for thorough investigation, non-destructive testing, analyses, and repair design. Another example is a seven story precast parking structure. The structure was under construction and reportedly erected out of plumb. Poor concrete placing practices and poor weld detailing led to widespread cracking in multiple structural elements throughout the structure...

Short Description:
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.
