GSSI, the world’s leading manufacturer of ground penetrating radar (GPR) equipment, announces the availability of a new accessory for the industry standard StructureScan Mini XT. The Palm XT is a miniaturized GPR antenna that is designed to greatly enhance the capabilities of the StructureScan™ Mini XT all-in-one GPR concrete inspection system. The handheld Palm XT antenna turns a basic StructureScan Mini XT into an advanced system by giving users unparalleled access in tightly spaced areas and enabling overhead scanning. Designed to withstand challenging construction sites, the Palm XT is an excellent choice for contractors who need to perform concrete scanning and utility locating services.
The 2300 MHz Palm XT antenna offers superior depth penetration and resolution. It features full keypad control via the antenna top that allows for remote control of the user interface. The antenna has seamless software integration and provides users with three data collection modes; standard, cross polarization, and side car. Standard mode requires no special set up, and is ready for plug-and-play operation. Cross polarization mode highlights non-metallic objects, such as PVC, and deemphasizes metallic objects like rebar and wire mesh. Side car mode transitions the survey wheel to the side of the antenna and allows it to fit into smaller spaces.
Rugged, compact, and flexible, StructureScan Mini XT is ideal for locating rebar, conduits, post-tension cables, and voids. The Mini XT can help identify structural elements, including pan deck and concrete cover, and can also provide real time determination of concrete slab thickness. StructureScan Mini XT is the perfect blend of price and performance, and is backed by a two-year warranty. Additional accessories for the StructureScan Mini XT include an extension handle with control button options, and the LineTrac XT. The LineTrac XT adds the ability to detect AC power and induced RF energy present in conduits.

Full-function remote control provides outstanding maneuverability
PELLA, Iowa, October 9, 2017 – The new Vermeer SPX25 vibratory plow is designed for fast and efficient cable/fiber and irrigation system installation. It features a full-function remote control that gives the operator a 360-degree view of the jobsite, helping to avoid potential obstacles and an unobstructed view of the product being installed. The SPX25 vibratory plow is compact, powerful and built with tracks to minimize ground disturbance.
“For applications like installing cable or fiber-to-the-home, contractors can face several challenges like narrow gates, fences and common backyard obstacles,” explained Ed Savage, product manager at Vermeer. “The SPX25 plow minimizes those concerns. We’ve eliminated the need for operators to run the machine from behind, which means they can stand in whatever location gives them the best view. This design has also allowed us to make the plow even more compact for excellent performance in tight areas.”
The Vermeer SPX25 vibratory plow is powered by a 25 hp (18.6 kW) Kohler gas engine that provides ample power for installing small pipes and cables at depths up to 12 inches (30.5 cm) and for boring underneath driveways and sidewalks using the optional Porta Bore attachment. The dual rubber tracks with a ground pressure of 3.7 psi (.3 bar) on the Vermeer SPX25 plow delivers great floatation in soft ground conditions and helps reduce jobsite restoration after an install. The lightweight plow offers a quick transport speed of 3.7 mph (6 km/h).
For efficient turning, while installing utilities around obstacles, the SPX25 unit is equipped with a pivot-mounted plow that has a 55-degree swing angle that automatically adjusts when turning.
An optional reel carrier can be mounted to the machine, helping to reduce the amount of jobsite equipment and labor needed on the jobsite. Contractors also have the option of adding a weight kit for added traction when working in hard ground conditions.

SANTA CRUZ ACCOMPLISHES EMERGENCY HORIZONTAL DIRECTIONAL DRILL FOR
LOMBARDI GULCH CROSSING
HDD provides a rapid and reliable way to replace aging steel pipeline
Overview
The City of Santa Cruz Water Department (SCWD) has long anticipated the need to assess, design and build a new pipeline system as part of the existing North Coast System (NCS) which delivers raw water to their water treatment plant. The existing NCS is a series of stream diversion structures and collection
conduits and includes approximately 16 miles of pipelines that are nearing, or have exceeded, their design life and must be replaced. The replacement pipeline is a series of phased projects and will provide a water delivery system that will be reliable for the next fifty years or more.
Phase 3 of the overall initiative included the replacement of 18,600 feet of primarily 24-inch diameter pipe using open cut methodology. Additionally, five trenchless crossings, one horizontal directional drill (HDD) crossing under sensitive environmental habitats and four horizontal auger bores crossing under California Department of Transportation and railroad right-of-ways were included in Phase 3.
In 2015, this phase of the NCS project had been designed but had not gone out to bid when a failure of a 1,200-foot critical section of the existing steel pipeline at the Lombardi Creek Crossing location prompted SCWD to schedule that section for immediate replacement. Site conditions at this location required replacing the pipeline using HDD installation methodology. Its location within the Wilder Ranch State Park elevated environmental concerns because the park has strong biological, scenic, cultural and recreational values.
The replacement of the Lombardi Creek crossing began in late 2015 after selecting the HDD Company from Granite Bay, California to be the contractor. The actual drill alignment length was approximately 1,300 feet with an elevation change of approximately 60 feet. Entry and exit angles were approximately 10 degrees. The final alignment was 25 feet below the bottom of the creek. 24-inch DR 18 Fusible PVC®
pipe was selected as the replacement pipe. Overall, the drill alignment and bore preparation took four weeks. While the bore hole was being drilled and reamed, the Fusible PVC® pipe was fused by Underground Solutions. Once the bore hole was prepared, the Fusible PVC® pipe was pulled into place,
a process that took approximately 8 hours. The replacement project took two months from mobilization to pressure test and the replacement pipe was placed into service after completion. This new segment will be tied into the new NCS Phase 3 pipeline when it is complete.
Project Manager Kevin Crossly stated, “The Lombardi Gulch HDD Undercrossing is the largest and longest installation of Fusible PVC® pipe to date for the City of Santa Cruz. The City was very pleased during all phases of the project with Underground Solutions which provided technical support solutions during design of the project. When the City experienced the 0.5 MGD leak and fast tracked the construction phase, Underground Solutions was responsive to the project requirements to secure, fabricate, deliver and fuse the 1,300 LF of pipe that was ultimately installed on a very aggressive schedule of approximately eight weeks. Fusible PVC® pipe is a great product that Underground Solutions will support and stand behind. We will definitely consider using Fusible PVC® pipe on future projects.”
