AlumaBridge, LLC produces two primary aluminum deck systems — an 8-inch-deep bridge deck to replace concrete on structurally deficient bridges and a 5-inch-deep deck alternative to steel grid decks. Newly designed end extrusions run along the edges of the deck and can be modified to accommodate various panel widths. These extrusions are also designed for guard rail connections. According to the company, the strength of structural aluminum mirrors that of monolithic concrete but is corrosion-resistant and only about one-fifth the weight.
ClearSpan Fabric Structures added three length options to its HD Building solutions — 160, 180, and 200 feet. The HD Buildings are available in both gable- and round-style designs and can be mounted as a freestanding structure or affixed to other foundations, such as ponywalls or containers. HD Buildings are made from triple-galvanized structural steel tubing for the frame and a 12.5 oz., high-density polyethylene (HDPE) rip-stop fabric cover. Since there are no internal support posts, the building allows for maximum usable space.

Pile Dynamics, Inc reengineered its Pile Integrity Tester for low-strain integrity testing of deep foundations, giving it a large and bright color screen, a lighter enclosure, and a USB port for data transfer. This model is available with one (PIT-V) or two (PIT-FV) channels of data acquisition, both traditional (wired). The PIT performs pulse echo tests and consists of a main unit, one accelerometer, and one handheld hammer. The PIT-FV is most often supplied with one accelerometer and one instrumented hammer, but may also be used with two accelerometers.
HP’s new HP Designjet SD Pro Scanner features a new contact image sensor technology with a dual-illuminating system and image enhancement software, helping users accurately reproduce detailed large-format documents at high speeds. It integrates with existing HP Designjet printers to add scanning and copying capabilities. The HP Designjet SD and HD Pro Scanners scan at 6 inches per second for color images and 13 inches per second for black and white images. Additionally, both scanners provide multipage PDF and scan to email, USB, and network capabilities.
Sure-Grip Concrete Liners extend the life of tanks, pipes and other structures, by combining the flexibility and chemical resistance of thermoplastics with the strength of concrete. Sure-Grip is available in a variety of resins (HDPE, PP, PVDF and ECTFE), thicknesses and sheet/roll dimensions and is ideal for new cast-in-place construction, rehabilitation projects and prefabricated elements such as concrete pipes and manholes. It’s also available with an anti-skid surface, a coextruded signal layer and a self-cleaning surface.
American Cast Iron Pipe Company said its 60-inch Series 2500 Flex-Ring boltless restrained joint valve is the first and the largest resilient wedge gate valve in the industry without flanged ends. According to the company, benefits of the valve include significant labor savings because it takes less time to install than flanged-end valves, no flanged joint fasteners to corrode, and the ability to deflect once it’s installed, making it ideal for soil that is shifting or settling such as in locations near structures or tanks. The valve is for use on ductile iron pipe and spiral-welded steel pipe.
Reinforced Earth® MSE retaining structures are an economical way to meet ordinary and extraordinary earth retention and load support needs for highways and bridges, railroads and mass transit systems, waterfronts, airports, loading docks, industrial and mining facilities and commercial and residential developments. Each wall is a coherent gravity structure, custom-engineered by The Reinforced Earth Company to project-specific requirements including applied loading, foundation conditions, and aesthetics. The key components of a Reinforced Earth wall are galvanized steel high adherence reinforcing strips or reinforcing ladders, granular backfill and precast concrete facing panels. The frictional bond between the backfill and the reinforcements is permanent and predictable and there is a reliable mechanical connection between reinforcements and facing panels.
Bentley Systems, Incorporated acquired BLUERIDGE Analytics, Inc., provider of SITEOPS site design optimization. SITEOPS uses cloud-based computing techniques to explore engineering alternatives and their costs. According to Bentley, SITEOPS performs site configuration simulations that fully assess millions of layout, parking, grading, and drainage options within hours; produces preliminary cost estimates and conceptual designs faster; optimizes site designs through advanced “optioneering;” and minimizes overall costs while ensuring engineering quality.
Presto Geosystems introduced GEOWEB MSE design freeware for GEOWEB geocell wall applications. The software creates vegetated and non-vegetated MSE designs based on the GEOWEB system for reinforced slopes, and for gravity and geogrid-reinforced walls. The software is based on industry-standard design methods and contains specific algorithms that capture the interaction between the GEOWEB system, infill and backfill soil, and geogrid reinforcement and specific factors of safety. In addition to performing the analysis, GEOWEB MSE software creates a full graphic design analysis output and cross-sectional drawings.
Impact resistant structural plastic has a cellular core surrounded by integral skins forming a totally integrated structure. Structural molded parts made from fiberglass reinforced HDPE have a high strength-to-weight ratio and have 3 to 4 times greater rigidity than solid parts of the same material of equal weight. Storm Rax are designed to withstand the conditions of pond structures – rough handling, high/low temperatures and long term weather exposure.
Lane Enterprises’ new StormKeeper™ family of chambers offers maximum performance, storage efficiency and value in a smaller footprint. The SK180 and SK75 chambers are injection molded from Virgin Polypropylene and designed with sophisticated Finite Element Analysis (CANDE) techniques to deliver the highest structural integrity and arch stiffness. The chambers, which exceed ASTM F2418, offer complete reliability to the engineer designing a retention or detention system, and provide the ability to meet almost all site elevation constraints.
Hollow structural sections (HSS) are structural elements that help engineers solve complex design issues. HSS are particularly well-suited for structures with large load demands, including vertical columns, diagonal bracing, long spans and seismic applications. With exceptional functional performance and flexibility, HSS are a superior, cost-effective alternative to open sections and built-up, welded box sections. Atlas Tube offers the broadest size range of HSS in North America — including the new ASTM A1085 specification — and is the exclusive provider of Jumbo HSS.
Catsurveys Group Ltd.’s Mobile Ground Penetrating Radar (MGPR) combines the benefits of GPR and corrected GNSS data. The MGPR uses multiple low- and intermediate-frequency antennas to boost data quality. Double-polarized antennas cover both longitudinal and transversal scans to create underground images. The mobile system enables rapid data collection, allowing the survey to be carried out in the office, reducing project time, health and safety risks, and lowering cost when compared with traditional push GPR.
Xerxes manufactures a wide range of aboveground and underground fiberglass tanks designed to meet the demands of the growing water and wastewater markets. Fiberglass storage tanks are a preferred choice compared to concrete, steel and poly storage tanks where corrosion can be a concern. Xerxes storage tanks are ideally suited for a wide range of applications including rainwater harvesting, fire protection, potable water, grease interceptors and onsite wastewater.
