Radiodetection’s RD1000+ provides high-performance subsurface imaging for buried utilities in a rugged and competitively priced Ground Penetrating Radar system. Designed for the utility industry, the RD1000+ features a wide-band sensor capable of detecting plastic and ceramic utilities at depths of up to 8m / 27’ deep. Once a utility is detected, the operator can simply reverse the cart to switch the RD1000+ into Locate Mode and determine the utility’s depth and position, simplifying utility identification.

Advanced DynaQ signal processing optimizes signal quality, providing real-time image updates and high levels of detail. Integrated digital filters and color palettes allow operators to pick out even small utilities located in differing subsurface materials and soil types. Operators can capture what’s on the display with a single touch. Locate images can be transferred to a PC from the Compact Flash card using the dedicated RD1000+ ImageView software to assist in documenting and analyzing surveys.

Built from durable, weatherproof (IP66 rated) materials, and supported by a range of wheel types and accessories, the RD1000+ can operate across rough or smooth terrain. The modular design also makes the system quick to service and repair. Weighing only 48lbs (22kg), the system is designed to be transported and assembled without requiring specialist equipment in less than two minutes. Key components can be packed in hard or soft travel cases, and a flight case is also available to protect an entire system during transportation.

*Detect non-conductive pipes and ducts…Ground Penetrating Radar can detect ceramic and plastic pipes and ducts which would otherwise require tracer wire or sondes to detect using an electromagnetic locator. The RD1000+’s ultra wide-band antennas enable detection of a wide range of buried utilities without introducing the cost or complexity associated with multiple frequency GPR.

*Locate and mark utilities in a single pass…Simply reverse the cart to enter locate mode to measure position & depth and characterize signals to ensure consistent surveying.

*Survey Reporting…Capture radar images direct from the screen and export using the dedicated ImageView software for analysis and use in survey reports.

*Designed to operate in almost any weather or terrain…Large, bright, real-time display allows operation even in bright daylight. Light-weight, rugged and weatherproof (IP66) system designed for use across challenging terrain. Optional larger wheels can be fitted to ease use across particularly soft or rough ground.

*Portable…The RD1000+ can be assembled on-site in less than two minutes, and can be dismantled without requiring tools, allowing compact storage and safe transportation. Soft and hard cases are available for transportation of the display unit; alternatively an optional flight case can be used to protect the entire system

*Advanced digital signal processing…Advanced DynaQ processing increases data / image definition and provides real-time imaging during surveys. Digital filtering helps the operator to eliminate unwanted signals and ground returns, while color palettes allow users to pick out even small utilities amongst differing subsurface materials and soil types.

*Designed for easy maintenance…The RD1000+’s modular design allows for replacement of a number of the key component parts without requiring specialist tools. Radiodetection’s service network provides quick and cost-effective repairs for sensors and displays.

Kapahulu road work fire raises concerns with other city projects

Brent Remadna – KHON2 Honolulu Hawaii. A fire that burned for hours and left two workers injured has lead the city to take a closer look at how they check for utilities. In February re-surfacing work began on Kapahulu Avenue. The project was supposed to take a little more than a year, but after crews struck a gas line, which resulted in a blazing fire, work has been halted.

“This was a freak accident where two lines from the two utilities crossed and so to get over the one the gas line went up and over,” said Robert Kroning, director of the Dept. of Design and Construction. The city does have plans to show where utilities are and even marks them on the road, but they said the plans are old and sometimes not accurate.

“It should have been annotated on the plans and somehow that got missed,” said Kroning.”That’s why we are going to make sure we go through more thoroughly.” Since the fire the city says that they are now taking a closer look at the Kapahulu roadwork and other projects as well.

“There are crews that are now concerned about other roads in downtown,” said Kroning. “So we are working to do this analysis for all the roads we have concerns where this may happen.” Now instead of just going off old plans the city is taking a closer look.

“We are going to get ground penetrating radar to help find the locations to find utilities a little better and not just go off the plans,” said Kroning. As far as when roadwork will continue, that is still up in the air.

“Exact timeline I can’t give you because we don’t know what we are going to run into,” said Kroning. “So as we go through the process of searching for the lines that are shallow and maybe have to lower some that we run into and that will determine how much longer it will be.”

Sinkhole swallows pickup truck in Palolo Valley…

Sinkhole swallows pickup truck while crews respond to water main break in Palolo Valley.

By Ramsay Wharton – HawaiiNewsNow Honolulu, Hawaii. BWS- Board of Water Supply crews are responding to a 16-inch water main break and sinkhole located on 10th Avenue and Hinahina Street. The water main break, which was reported Thursday at around 6:05 a.m., ripped up the sidewalk and buckled the road near the sinkhole. Neighbors were urged by police to move their vehicles, but a Ford pickup truck was located right over the gushing main break, and in a matter of minutes, the truck collapsed into the roadway, uprooting the adjacent sidewalk. Honolulu police said they tried to get the truck out of the way before the road collapsed, but were unsuccessful.

As of 8:30 a.m., the truck was still submerged in the sinkhole. However, no injuries have been reported. The truck owner’s wife, Sala Costa, said she believes the truck and its collapse ultimately saved more water from causing damage to the couple’s home on the corner of 10th Avenue and Hinahina Street. She said the sound of rushing waters woke her up. They couldn’t escape their front yard gate because of the water coming into their yard.

Costa said she managed to climb over the fence with the help of police and firefighters. Water has not entered the home, but their garage is flooded and damaged some of their property and a shed in the back, she said. A similar water main break occurred about eight months ago and caused about $100,000 of damage to their home. They also just finished relaying new grass in their front yard, Costa added.

“Our whole yard was flooded and in fact, they just got through putting in new grass in the yard a week ago,” she said. BWS crews managed to shut off the water at 8:20 a.m. Approximately 23 customers have been impacted by the water main break. All lanes on 10th Avenue, between Hinahina Street and Hardesty Street, will remain closed. Repairs are expected to continue throughout the day and into the evening, BWS said.

100+ traffic cameras restored after construction damage…

Post date May 14, 2015

By Kristine Uyeno – KHON 2-News. All traffic cameras damaged in a construction mishap Wednesday night were back up and running Friday. Crews worked day and night Thursday to restore 101 of the city’s 265 traffic cameras in Leeward, West and Windward Oahu. A contractor for the Honolulu rail transit project accidentally damaged a fiber optics line Wednesday night near Aloha Stadium, according to the Honolulu Authority for Rapid Transportation.

No one was hurt, but the damage temporarily affected nearly half of the city’s traffic camera coverage, including some of the island’s most congested roads in Aiea, Pearl City, Ewa, Kapolei and Kaneohe. “It’s uncommon to have half out, but you know it’s a construction project, accidents do happen,” said Ty Fukumitsu, Honolulu Transportation Services. Cameras in other areas, like town and East Oahu, were not affected.

As crews worked to restore the cameras, the city used the state’s GoAkamai.org website to monitor traffic along with Google maps. If those website showed congestion, “I would actually have to send personnel out there to do some timing adjustments because we need to see what’s going on. We don’t want to guess and guess wrong, so we do have personnel on standby, actually this afternoon, to… physically go to a site and if need to adjust the signal timing,” Fukumitsu said.

City officials said they had other eyes on the road, including the Honolulu Police Department, HART and other drivers who will call them with updates. Contractor Kiewit was conducting utility relocation work along Kamehameha Highway shortly before midnight when the cable was damaged, and will pick up the tab for repairs. HART and Kiewit apologize to drivers for any inconvenience.

Lava Flow Update – 1/30/15 – by Big Island Now Staff.

Over the past week, minimal advancement has been seen in the major breakout portions of the June 27 lava flow. Hawai’i County Civil Defense reported continuous stalls at every portion of the lava breakouts following its Friday morning overflight assessment.

The once leading flow front heading towards the Pahoa MarketPlace continues to show no advancement, along with the south margin breakout that was active during the same time. During its overflight, Civil Defense made note that the distal breakout that spawned from the north margin continues to show no advancement, although signs of activity and flow pad widening are occurring just behind the stalled front.

No advancement has been seen in this portion of the breakout since between Sunday and Monday morning, when the flow sluggishly advanced 50 yards. At the current time, the north margin breakout remains about 0.36 miles from Highway 130 in the area west of the Pahoa Police and Fire stations.

Two additional breakouts along the north margin breakout, 1-1.5 miles upslope from the stalled original flow front, have displayed little activity and have not shown signs of advancement. Officials have been closely monitoring various breakouts along both margins of the flow, as well as within the flow pad. At the time, none of the activity is posing an immediate threat to communities in the area.

Both Civil Defense and Hawaiian Volcano Observatory continue to maintain a watchful eye on all lava flow activity. Should any changes occur the public will remain informed. Friday morning smoke conditions were reported as light, with a light south wind blowing smoke in a north/northeast direction. As usual, these smoke conditions have the possibility of changing and individuals who are sensitive are advised to take necessary precautions.

According to officials, there is currently no brush fire activity and fire conditions continue to be monitored closely.
