01. Unmanned survey vehicle
Milrem and Leica Geosystems introduced Pegasus:Multiscope, an unmanned ground vehicle (UGV) for off-road use. Combining Milrem’s Multiscope UGV and Leica Geosystems’ Pegasus:Two mobile mapping sensor platform, the UGV provides faster, costeffective, and flexible technology for commercial and government use, including civil engineering, the companies said. The UGV’s 0.98 psi to 1.635 psi ground pressure allows it to traverse any type of terrain up to 45° rise, including mud, sand, or snow, and potentially dangerous or difficult areas, such as unstable riverbanks. Maximum speeds are 15 to 22 mph. Base length is 79 inches; width ranges from 36 to 83 inches.
02. Composite trench covers
Fibrelite’s HS-20 load-rated composite trench covers have been selected by one of the nation’s largest metropolitan electrical utilities for a high-profile rebuild of a 345-kV bulk power substation. The substation is located in a lowlying coastal area that was subjected to severe flooding caused by Hurricane Sandy in 2012. In 2015, Fibrelite and Trenwa, a manufacturer of precast concrete trench, jointly released a new line of Fibrelite composite trench covers designed specifically for Trenwa’s precast concrete road crossing trench (HS-20). The Fibrelite trench covers are non-conductive, chemically resistant, lightweight, yet extremely durable and will withstand heavy traffic loading and harsh field conditions, the company said.
03. Rugged smartphone
Handheld Group’s new Nautiz X2 rugged Android device integrates a high-quality scanner, camera, and mobile phone. Available features and capabilities include a quad-core processor and Android 5.1 Lollipop OS; high-speed scanners with 1D or 2D capability; integrated 8-MP camera with autofocus and flash; 4G/ LTE Android phone functionality; Google GMS, allowing users to use Google Maps and download Play Store apps; sunlight-readable 4.7-inch capacitive display with Gorilla Glass touchscreen; and IP65 ingress protection rating against dust, sand, and water immersion. It also meets stringent MIL-STD-810G military test standards. The Nautiz X2 measures 150 mm by 73.5 mm, is 16 mm deep at the keyboard, and weighs 230 grams.
04. Modular bridge handbook
Acrow Bridge released The Acrow American Engineering unit Handbook-5th Edition, which reflects improvements recently made to the Acrow 700XS Modular Bridging System. The handbook is intended to explain the design characteristics and requirements of ordering and installing an Acrow 700XS Bridge. Acrow bridging systems are designed and engineered to carry highway and pedestrian loadings as specified by the American AASHTO bridge design code, and comply with most national standards. Acrow components are made entirely from steel and include a hot dipped galvanized finish. The bridges are assembled using only pins and bolts, requiring no site welding. All components are reusable.
05. Cloud-based BIM
Invicara recently released BIM Assure, a collaborative cloud solution that, according to the company, unlocks BIM data and helps the entire project team streamline BIM data management. BIM Assure’s intelligent rules help users to identify and resolve issues quickly to improve BIM quality and then sync the corrections back to the source model, Invicara said. In addition, because it is cloud-based, BIM Assure provides a common BIM environment that lets architects, engineers, contractors, and owners share models and manage data, creating new opportunities to streamline design and construction workflows and improve project delivery.
06. Concrete repair codes
The American Concrete Institute (ACI) published the new ACI 562-16: Code Requirements for Assessment, Repair, and Rehabilitation of Existing Concrete Structures and Commentary. These new code requirements combine the ACI’s historical knowledge with state-of-the-art resources on the evaluation, repair, and rehabilitation of concrete buildings. ACI 562-16 provides minimum performance requirements that address the unique nature of existing building construction, rather than specific formulas that must be followed in any situation. Included in the requirements are all aspects of concrete repair, from conception to completion, including the basis for compliance, evaluation and analysis, design of structural repairs, durability, and construction.

08. Geotechnical drill rig
Little Beaver introduced the Lone Star LST1 heavyduty geotechnical drill rig, which drills to 100 feet with an optional 4.25-inch hollow-stem auger. The new geotechnical rig’s torque increased from 500 foot-pounds with the standard model to 1,100 foot-pounds, doubling the drill depth to 100 feet. In addition, it provides users with 8,500 pounds of push/pull-back force, compared with 5,000 pounds on the standard model. The rig comes with Little Beaver’s SSK1 kit, which includes a tower, pulley, third hydraulic valve, and a steel cathead that allows users to perform standard penetration tests with Little Beaver’s optional 140-pound safety hammer, split spoon samplers, and AWJ drilling rod.
