Industrial Asset Life Cycle Infographic

Posted on by Marci Broderick

Much of our nation’s infrastructure is at the end, or past its serviceable life. HJ3’s carbon fiber technologies have advantages that go beyond cost savings and asset life extension. The environmental savings are huge. This infographics details some of the positive impact carbon fiber solutions provide.

U.S. ranks well behind many other countries in overall infrastructure quality in 2014-2015, coming in at 16th.

By 2020 the transportation infrastructure investment gap will be -$1 trillion. Investing in rail expansion would have many long-term benefits both financial and ecological. It is estimated that traffic congestion caused U.S. drivers to waste around 3 billion gallons of fuel in 2014. When time, fuel, car maintenance and lost productivity are factored in, the price tag is a staggering $160 billion dollars nationwide. Investing in passenger and freight rail expansion makes financial sense. This infographic highlights some of the other costs and benefits investing in rail expansion would provide.

Giving Back

HJ3 Giving Back

Giving back is an integral part of HJ3’s corporate culture. At HJ3 we pledge 1,000 hours of community service each year.

Each year as part of our commitment to give back to our community, we work with the Salvation Army to select families for our annual holiday Adopt a Family event. In years past, we would adopt several families. This year we adopted one family, so that we could make a big difference for a struggling family. We adopted a single mother with 6 children. One of her children is special-needs and another was hit by a car and sustained many serious injuries. Mom took off work to care for her injured child, which had a major impact on the family.

We’ll deliver gifts and food that were purchased and wrapped with the children and mom in mind.

Other Giving in 2015

This year HJ3 donated to Pima Animal Care Center, providing food, supplies and money for the care of pets in need. We also participated in our annual Cystic Fibrosis Walk, and the 2015 Walk For Wishes Tucson, which is part of the Make A Wish Foundation. HJ3’s contribution helped Walk For Wishes Tucson raise thousands of dollars to help grant the whishes of children with a life-threatening medical condition.

We would like to thank our customers and friends for making 2015 a special year. The HJ3 family is committed to enriching our community and spreading hope and joy. Have a happy and peaceful holiday.

Bridge Pile and Truss Repair

Posted on by Marci Broderick

For this bridge and pile repair project, HJ3 repaired and strengthened a bridge that had 93 concrete piles and 2 reinforced trusses in need of repair and strengthening. HJ3’s patented products were used to repair and strengthen the piles 10 feet above and 5 feet below the waterline.

For this project, HJ3 had an above-water and below-water team of certified installers. The degraded concrete was removed and the piles and trusses cleaned.
5 Bridge with many piles over water
The bridge was repaired and strengthened above and below the water, then wrapped with HJ3’s carbon fiber and CFRP. The piles above water had a UV and pH protective coating applied over the carbon fiber.

DESIGN: HJ3 relies on ACI-440.2R-08 ” Guide for the Design & Construction of Externally Bonded FRP Systems for Strengthening Concrete Structures

STRENGTH: HJ3 verified the strength of its underwater system in accordance with ASTM D3039.

HJ3’s team of engineers will design custom structural solutions for you.

There are 87,359 Dams in the US. Their average age is over 53. Many are in need of repair and are considered to pose a high or significant hazard potential.

Many communities are located downstream of dams.

Bridges and El Nino

By Elizabeth Rosenberg

According the National Oceanic and Atmospheric Administration’s Climate Prediction center, this year’s El Nino event is “significant and strengthening,” evidence of this is based on current atmospheric and oceanic features, including warming sea surface temperatures. In a recent advisory report, the NOAA stated, “There is a greater than 90% chance that El Nino will continue through Northern Hemisphere winter 2015-16, and around an 85% chance it will last into early spring 2016.”

Current predictions reveal this El Nino event may be as serious as the El Nino of 1997, which resulted in an estimated 23,000 fatalities and approximately $45 billion in damage worldwide. In the United States, 35 counties in California were pronounced disaster areas, as rain caused severe flooding and mudslides. In addition to this, substantial flooding resulted in about $300 million in damage to the state highway system. While, it is anticipated that this El Nino will help to alleviate California’s current drought, it could potentially take the state from one extreme to another with severe flooding. Other areas of the Southwest, including Arizona experienced serious flooding as well during the 1997 El Nino event, contributing to growing concerns over the negative impact these anticipated heavy rainstorms may have.

In late July 2015, an Interstate 10 bridge collapsed in between California and Arizona due to flooding. This collapse is further evidence of the critical need for infrastructure repair in the United States and has contributed to worries over more bridge and structure failures as a result of El Nino. The bridge was 48 years old and had recently passed a safety inspection less than 6 months before its collapse. Sudden and intense flooding led to the collapse, and with several dozen similar bridges on the same stretch of the interstate, anxieties are increasing as heavy rainfalls are projected in the upcoming months.

There are 25,406 bridges in California and 8,035 in Arizona. In both states, 1 in 10 bridges are rated as structurally deficient, falling in line with the national average and meaning they require significant maintenance, rehabilitation, or replacement due to deterioration or damage. In California and Arizona, about 17% and 13% of bridges respectively, are functionally obsolete, meaning they no longer meet current design codes. This means that in the two states, close to 1 in 4 bridges are deficient, and with numbers this extreme, it is vital for safety that they be strengthened and brought up to code standards. Infrastructure repair and improvement is a serious topic and has been at the top of the nation’s agenda for some time; state-of-the-art improvements in material and construction methods, provide a positive outlook. In a continuous effort to repair infrastructure and prevent the loss of lives and resources, HJ3 engineers innovative solutions to strengthen bridges and overpasses, repairing deficient structures with advanced composite solutions.


Arizona has 8,035 bridges

  • 256 are structurally deficient (9.91%)
  • 684 are functionally obsolete (12.82%)
  • 940 deficient (22.73%)
  • 23.71 % of the area of all bridges is deficient – 10.75% is structurally deficient


California has 25,406 bridges

  • 2,501 are structurally deficient (9.84%)
  • 4,306 are functionally obsolete (16.95%)
  • 6,807 deficient (26.79%)
  • 34.61 % of the area of all bridges is deficient – 11.33% is structurally deficient
