On February 11, 2022, New Jersey Department of Transportation (NJDOT) awarded a $5,000,000 Local Transportation Project Fund Grant to the City of Trenton to support the Trenton Mobility and Opportunity: Vehicles Equity System (MOVES) project. The core vision, goals and features of the project - an autonomous vehicle transportation system capable of serving 90,000 Trenton residents and commuting workers -- were outlined in a Request for Expressions of Interest (RFEI) issued in December 2021.

The system is expected to comprise 100 autonomous, electric shuttle vehicles and 50 kiosks and will operate solely as an on-demand system, with no fixed routes or schedules. The vehicles will be handicapped accessible and accommodate up to eight passengers.

Kiosks will be located at popular locations and high-density residential/commercial areas within a five-minute walk by over 90 percent of Trenton residents. Riders will be able to hail the vehicles through mobile devices or through an interface at each kiosk for those lacking access to a mobile device.

Through its partnership with Princeton University and the Corporation for Automated Road Transportation Safety (CARTS), NJDOT supported an extensive public outreach process to support the development of the RFEI. This outreach revealed several notable current conditions: 70 percent of Trenton households have one or no personal vehicle; due to land use decisions of prior decades and the lack of frequent bus service, seniors have to take circuitous bus rides, schedule an access-a-ride in advance, or walk significant distances to access destinations for everyday needs; and high school students living within two miles of the high school were without access to a bus because of a national bus driver shortage. The new system is intended to alleviate these and other limitations of the current transportation structure. The public engagement informed the RFEI and generated five goals for the program.

Goals of the Program

Safety

Autonomous vehicles can provide improved safety as they are not subject to human fallibilities, such as driving distracted or speeding. Some acclimation will be needed to ride in a vehicle with no driver. For the first two years of the project, vetted safety hosts will be on the vehicles to assist riders in understanding and navigating the system. The project will initially be limited to its operational design domain while on public roads.

NJ State Transportation Innovation Council Discusses Trenton MOVES at their 1st Quarterly Meeting of 2022

Equity

A significant majority of Trentonians live in Areas of Persistent Poverty, own one or no cars, and spend a high proportion of their income on transportation within the City. The program must serve the transportation needs of all Trenton residents, particularly those with limited transportation access due to economic or physical hardships. The service will aim to be inclusive both in terms of communities served and user experiences.

Affordability

The program will aim to be both low cost to the rider and the taxpayer. As NJDOT wants it to be both equitably and fiscally viable long into the future, its costs should be attainable and fares should be affordable. The rider should pay fares comparable to transit service, and far less than would be paid for ride-hailing and taxi services. Trenton MOVES will also create a public-private partnership to assist with the development of the on-demand mobility system and anticipate reduced costs through scaling and innovative funding mechanisms.

Sustainability

As New Jersey will be phasing out the sale of gasoline powered vehicles by 2035 to help reduce emissions, all of the initial 100 AVs in the Trenton MOVES project will be 100 percent electric. Additionally, the on-demand function stands to reduce average vehicle occupancy, vehicle miles traveled, and greenhouse gas emissions for local trips within Trenton.

Efficiency

To maximize the convenience of the on-demand mobility service, Trenton MOVES seeks to minimize wait times, ride times, have low circuity during shared rides, and reduce VMTs, particularly when the vehicles are empty. This goal will be achieved through active fleet management, dynamic repositioning, optimal routing, data analytics, etc.

How it will work

Trenton MOVES, Planned Operational Design Domain. CARTS

NJDOT anticipates a four-phase process to enable the autonomous vehicles within Trenton, and eventually to expand statewide and potentially beyond. Availability of service in Trenton is anticipated for early 2024.

Phase One will consist of the verification of the autonomous vehicle concept. The company selected to create this on-demand mobility service will first operate the autonomous vehicles on and around NJDOT’s Ewing campus to verify functionality in low stress environments.

Phase Two will be a proof of concept. Once the automated vehicles are shown to be effective, 100 vehicles will be placed on the public roads within a limited Operational Design Domain (ODD). This ODD will consist of major public centers in Trenton such as the Capitol Complex, schools, public housing, grocery stores, the Trenton Transportation Center, etc. A kiosk will be placed at each of these points to allow people to “call” to the vehicles.

Phase Three will be proof of societal value. In the third phase, the ODD will expand to all of Trenton to the point where 95 percent of the population is within a 5-minute walk of any kiosk. This expansion will demonstrate effectiveness of service, and scalability in an urban setting.

Phase Four is proof of network-scale economics. Once proven effective in Trenton, the program and the service could be launched throughout Mercer County, and in densely populated places in New Jersey such as Atlantic City, Camden, Newark, and New Brunswick. If those cities continue to prove effective in terms of service scalability, the autonomous vehicles can then be launched in more cities nationwide.

Upcoming Event - Princeton SmartDrivingCars Summit

From June 2nd to June 4th, CARTS and Princeton University have organized a gathering of leaders from within the industry, academia, public sector, and local communities to discuss the progress being made on the autonomous vehicle transportation. This year there will be an extensive discussion on Trenton MOVES as the program moves forward. To learn more, click here.

National Operations Center Webinar to Feature NJDOT’s Commercial Vehicle Alerts Initiative

The National Operations Center for Excellence will hold a webinar featuring New Jersey and Colorado DOT initiatives to establish private sector partnerships that use crowdsourced data to deliver real-time information to commercial vehicles to improve the safety of all road users.  Transportation agencies can now deliver in-cab alerts about road conditions through connected truck service providers to help commercial vehicle drivers approach and react more quickly to roadway incidents, work zones, and adverse weather conditions. Follow this link to register for the Crowdsourced Data for Commercial Vehicles webinar.

At the 1st Quarter 2022 STIC meeting, attendees received a briefing about the Commercial Vehicle Alerts initiative being undertaken by NJDOT and its several partners to proactively deploy alerts to improve safety and traffic incident management. Sal Cowan, NJDOT Senior Director, Transportation Mobility, was joined by Amy Lopez, Director, Public Sector Services and Smart City Strategy for INRIX, and Marc Nichols, Director, Government & Industry Partnerships for Drivewyze.

UHPC Bridge Preservation and Repair – NJ Efforts Highlighted

FHWA promotes UHPC for Bridge Preservation & Repair through its Every Day Counts (EDC-6) innovations. The FHWA's EDC Newsletter of April 28, 2022 featured Rutgers University's state-of-the-art Bridge Evaluation and Accelerated Structural Testing (BEAST) center.  FHWA has sponsored the use of the BEAST to evaluate emerging bridge preservation technologies including UHPC.  Below is a reprint of the newsletter article that recognizes these efforts as its Innovation of the Month for UHPC Bridge Preservation and Repair.

BEAST® Facility (Credit: Rutgers University)

Wouldn’t it be great to quickly test the performance of a UHPC bridge deck overlay? It can be challenging to test and evaluate the long-term performance of new bridge preservation innovations because it would normally take years of monitoring the in-service behavior of such a technology on actual bridge structures to make an adequate assessment. Alternatively, Rutgers University’s state-of-the-art Bridge Evaluation and Accelerated Structural Testing (BEAST®) center provides a new opportunity to evaluate emerging preservation technologies. Built in 2015, the BEAST facility aims to develop high-quality data of bridge deterioration and to expand our knowledge of bridge performance through full-scale accelerated testing. The facility is capable of enclosing a 50-foot long bridge within an environmental chamber and subjecting the bridge to realistic rolling wheel loads, freeze-thaw cycles, and even the application of deicing chemicals. As a result, this facility can impose 10 to 20 years of ageing in less than 12 months.

FHWA is sponsoring the first project to utilize the BEAST® facility, and seeks to establish the long-term performance of bare reinforced concrete bridge decks and overlay systems among other variables. A two lane, 50 foot simply-supported bridge built with steel girders was constructed and began accelerated testing in 2019. To date, it’s been subjected to over 2-million passes of rolling load, 85 freeze-thaw cycles, and over 3000 gallons of salt brine. As a result, deck deterioration has reached a point where, in practice, an overlay would commonly be installed for rehabilitation and preservation purposes.

UHPC is one of the overlay systems that will be installed on this bridge specimen for evaluation. The UHPC overlay will be installed using materials and construction practices that are commonly deployed in the field. Once installed, accelerated testing will resume for at least 12 months, or until significant deterioration is again observed. Data will be collected, which will help establish quantitative measure of the overlays’ ability to perform long-term and under realistic conditions. Data already shows that UHPC is long-lasting and resilient, but at the end of this research, researchers will be able to say with greater confidence how long UHPC overlays may last in service.

Exploring Strategic Workforce Development: An Interview with NJDOT’s Human Resources

FHWA is promoting Strategic Workforce Development in highway maintenance, construction and operations.

FHWA is promoting Strategic Workforce Development in highway maintenance, construction and operations.

Strategic Workforce Development, an FHWA Every Day Counts (EDC) Round 6 innovative initiative, anticipates collaboration between government agencies, trade organizations, private agencies and communities to prepare individuals for the construction workforce. The demand for workers in highway maintenance, construction and operations is growing, as is the demand for new skill sets required for work with emerging technologies. An important element of this initiative is the recruitment and retention of women and minorities in the construction sector.  Through on-the-job training and supportive services program, NJDOT is exploring ways to work with contractors, contracting associations, and unions on shaping their future workforces, including programs aimed at increasing representation of women, minorities, and other disadvantaged populations in the construction and operations workforce.

We spoke with Kelly Hutchinson, Director, Human Resources at NJDOT about ongoing and planned workforce development initiatives at NJDOT.

Workforce Development at NJDOT

Q. We know that NJDOT engages in a variety of innovative programs to attract and retain your workforce. Could you update us on the status of some of these programs?

Operations Apprenticeship Program

NJDOT’s Operations Apprentice Program offers a structured path to advancement

NJDOT’s Operations Apprentice Program offers a structured path to advancement.

This program began in 2015 to provide consistent training and skills for workers in Highway Operations and to establish a path to advancement and has focused on developing a job title structure and staffing profile for participants as well as both on-the-job and classroom training. We are still promoting the program and trying to get our numbers where we want them to be. We will be testing our third of four groups of mid-level individuals at the end of April 2022.

NJ Supervisory Training Empowering Performance (STEP) Training

This program is focused on teaching management skills and several hundred NJDOT employees have completed this very beneficial initiative. The Civil Service Commission provides this training, which has been on hiatus due to the COVID-19 pandemic as instructors prefer in-person classes. We offer a two-day, in-house training on DOT-specific supervisory issues like the supervisor’s role in promoting staff, leaves of absence, working test periods, performance assessment reviews (PARS) and discipline to build on what participants learn in STEP, but we may opt to offer this in-house training first if there is an ongoing delay in STEP availability. We have a lot of new staff advancing to supervisory and managerial roles who could benefit from this training. We would also bring in small groups from this supervisory cohort to participate in and benefit from a few Lunch & Learn sessions. In the past, these smaller group sessions have been very helpful for sharing experiences.

Leadership Academy

This is a Transportation specific Leadership Academy that focuses on the importance of soft skills related to management. In April, the NJ Turnpike Authority will be hosting this program locally with instruction from Dr. Tom DeCoster. Many of our manager-level and future directors will be attending, along with staff from NJ TRANSIT and the Turnpike Authority.

Skill Enhancement for Clerical and Administrative Professionals (SECAP)

This program was originally focused on skill enhancement for staff in clerical positions. Now, more individuals are being hired to fill administrative professional roles, rather than the traditional clerical roles. Persons with technical capabilities, such as policy writing and budget preparation, are filling these roles. In response, we are considering revamping this program to best support the needed skill sets related to these positions.

Administrative College

This program is ongoing and focuses on offering courses on topics such as financial wellness, mental and physical health, and technical skills that can be mastered in a couple of hours. We conducted a survey pre-pandemic to identify what our employees wanted in Administrative College courses.

Promotion of Asst. Engineers to Senior Engineers

NJDOT engineers participate in on-site training as part of a program that moves individuals from journey level to mid-level positions.

NJDOT engineers participate in on-site training as part of a program that moves individuals from journey level to mid-level positions.

This effort was initiated about seven years ago and we have continued the practice, adding programs for most journey level professional titles in Human Resources, Budget, Planning, Accounting, and Information Technology. When participants have completed one year past their initial training and have been in their journeyman title for two years, management determines whether they are performing higher level work and have mastered the technical skills to be considered a technical expert in the particular area. After three years, they may be considered for reclassification.  Management makes recommendations and provides written justifications to advance persons based on established criteria and must describe why they are recommending an individual, or why they are not. HR ensures that each individual has completed enough time in the title and gives a provisional appointment, but the candidate needs to pass the Civil Service exam to confirm their promotion.

This effort reflects both a retention strategy and a strategy to help bridge the supervisory gap resulting from retirements.

Succession Planning

Promoting continual skill development among NJDOT staff is a priority.

Promoting continual skill development among NJDOT staff is a priority.

Moving forward, NJDOT succession planning training and development will likely be less formalized than the previous NJDOT program. In this former program, participants were selected through an application process, which, in my opinion, may not have been ideal for all employees. Training and development should happen daily, at all levels, and should not be programmed by Human Resources. We are looking to promote parity, transparency and equity through the training programs we just spoke about. Our Leadership Academy and STEP program help workers to advance and instruct supervisors on how to support training and development of all employees. We are depending on management and senior leadership to work on a smaller scale. We want to provide the same level of opportunity to everyone and see who rises to the occasion.

Q. In a presentation to NJ STIC last June, former NJDOT Human Resources Director Michele Shapiro noted that you would be working on trainings for both the Construction Inspectors Apprenticeship program and the Engineering Technician Apprenticeship program. What is the status of these new programs? Do you anticipate developing similar programs for other job titles?

We have the new titles in place, but we do not have the formalized training program developed yet. I have spoken with Asst. Commissioner Snehal Patel and we will be collaborating with the Construction Director to start building the program this summer. Our plan is to update the existing 10-module program for the Resident Engineer Construction Inspectors to adapt to the Apprenticeship program.

Q. We had heard of the possible expansion of experience-based hiring. Are there any updates to this initiative?

Automotive and Electrical Mechanics would be the titles we are considering for a possible formalized program. There are trainees now but we don’t have a formal program. With all the advances in technology, we would like to find a community college partner to provide training and build a title structure based on the new technologies and see if it would increase the salary determination. We have trouble competing with private industries for candidates from these two trades. We are continuing efforts to receive approval for the program from Civil Service but effort was halted with the pandemic.

Q. Does NJDOT have plans to offer internships or similar positions?

We have a Summer Student program called Temporary Employment Services primarily targeted to professional titles. We do not refer to the program as an internship because participants are paid but do not earn academic credit. Typically, we accept rising college seniors, but if applications are light in a given cycle, we sometimes accept sophomores and freshmen as well. Pre-pandemic, it was a great pipeline for permanent positions with the department. In 2019, we had 55 students in the program, paid $20/hour, and 20 percent were hired for full-time positions with NJDOT. With our late start this year, we will have 20 participants. Some may stay with us into the school year, working part-time up to 944 hours per year as permitted by Civil Service.

NJDOT Human Resources staff attend career fairs to raise awareness of rewarding jobs in transportation.

NJDOT Human Resources staff attend career fairs to raise awareness of rewarding jobs in transportation.

The program is beneficial to participants as they receive work experience while earning wages. We recruit candidates via virtual and in-person career fairs, partnerships with alumni of the program and community organizations, campus organizations and using Handshake (an app that connects students on college campuses with open positions, mainly internships and entry level jobs). When we meet with students and other prospective hires, we focus on communicating how NJDOT offers dynamic, interesting, rewarding, and purposeful career opportunities.

Our talent acquisition team facilitates recruitment efforts and includes a diverse group of DOT subject matter experts in addition to our Human Resource representatives. Specifically, members of the team reflect a diversity of ages, genders, races/ethnicities, and career stages. Some are alumni of the Temporary Employment Services program. Also important, team member subject matter expertise varies (e.g., structural, environmental). We have found success with the talent acquisition team as members make personal connections with candidates as they discuss their roles at DOT and opportunities with the department.

Developing the Highway Construction Workforce

Q. There seems to be a lack of awareness – especially among women and minority persons – about jobs/careers in the highway construction industry. Do you know of programs that have been effective at building awareness of job opportunities in transportation in New Jersey?

To recruit a diverse workforce, NJDOT Human Resources focuses on forging relationships with community organizations such as the Society for Hispanic Engineers, Society for African American engineers, Asian American engineers, LGBTQ+, and STEM programs.  We use LinkedIn a great deal to target engineers and collaborate with New Jersey Youth Corps to spread the word on career opportunities at NJDOT.

We also successfully partnered with the Trenton Soup Kitchen, working with job specialists to inform those accessing the kitchen about construction apprenticeships and Highway Operations Tech positions. We have partnered with the National High School Guidance Counselors Association for New Jersey and were able to post in their newsletter about job opportunities that do not require experience via our highway operations tech program.

NJDOT’s programs for career are effective recruitment and retention tools.

NJDOT’s programs for career are effective recruitment and retention tools.

In 2019, we increased representation of African American male applicants by 93 percent for Highway Operations Tech positions. We achieved this goal by reaching out to our many community partners, with 100 African American applicants from the Trenton Soup Kitchen. Finally, we partner with the NJ Department of Labor, One-Stop offices, and attend county and other virtual and in-person job fairs.

Q. Reliable transportation and child care are often cited as roadblocks to entry into the construction sector, particularly for women and minority candidates. What strategies could help to address these issues? Are you aware of any model practices or programs to support women and minority populations looking at the highway construction trades?

We had a program for parolees several years ago that focused on identifying job opportunities for them in locations with good transportation networks, such as Jersey City and Newark.

NJDOT does offer an employee subscription van pool (pre-COVID-19) that accesses various public transit stops near DOT headquarters.

The newly announced Trenton MOVES project seeks to deploy 100 on-demand Autonomous Vehicles (AVs) throughout the state capital; when deployed, it could prove to be great service for helping people access employment opportunities.

Q. Have you worked with the NJ Council of County Colleges to look at possible programs that might advance NJDOT’s goals for workforce development? Do you work with the NJDOL Office of Apprenticeship?

We do collaborate with NJ DOL and with the One-Stops and Career Centers. However, our apprenticeships are not true apprenticeships by federal labor standards, but have similar components. Because we work with Civil Service titles, it is much more difficult for us to be recognized as an official apprenticeship program.

We also have a tuition aid and reimbursement program, at the public college rate, for employees as long as their course of study relates to transportation.

"Yes, we can work with them and are very interested in building these relationships."

Looking Ahead

Q. What strategies should be pursued to encourage more New Jerseyans to consider a career in the construction industry? Who should be leading or involved in those efforts?

Creation and implementation of an awareness campaign to highlight construction career opportunities would be helpful, as such an effort could amplify the message that you don’t have to look a certain way to work in construction. The campaign should highlight the diversity of workers and work options in the construction industry. A team of “ambassadors” comprised of local union representatives, NJDOT staff, and others can describe the different kinds of work available within construction and showcase opportunities to increase interest in the profession.

Q. There have been a number of grant funding opportunities through the Department of Labor for pre-apprenticeship and apprenticeship programs. Is NJDOT able to work with other organizations or academic institutions to build programs using these funds?

Yes, we can work with them and are very interested in building these relationships.

NJDOT Tech Talk! Webinar – Research Showcase: Lunchtime Edition 2022

On April 21, 2022, the NJDOT Bureau of Research hosted a Lunchtime Tech Talk! webinar, “Research Showcase: Lunchtime Edition!”. The event featured three important research studies that NJDOT was not able to include in the NJDOT Research Showcase virtual event held last October. The Showcase serves as an opportunity for the New Jersey transportation community to learn about the broad scope of academic research initiatives underway in New Jersey.

The three research studies focused on evaluation and testing of the performance and durability of materials and pavement for use in transportation infrastructure. After each presentation, webinar participants had an opportunity to pose questions to the presenter.


Evaluating the Potential of Using Foamed Concrete as the Insulation Layer for Pavements in Cold Regions. Cheng Zhu, PhD, PE, Assistant Professor, Rowan University, Center for Research and Education in Advanced Transportation Engineering Systems (CREATES)

In cold-weather areas, water freezes and thaws in the subgrade layer of the soil and causes weak zones in the subgrade that affect surface layer performance. These weaknesses appear as pavement surface distress and cracking. To protect the subgrade, insulating material is used.

Click for PDF

Extruded polystyrene (XPS) boards are commonly used as insulation but face deterioration over time with water infiltration, and installation is time-consuming and labor-intensive. This study looked at the potential for using foamed concrete as an alternative material. The study also looked at the methodology of selecting optimum parameters that balance mechanical strength and insulating effect. When density is low, more air bubbles provide more insulation, but more density gives higher mechanical strength.

Some of the results found through laboratory testing and large-scale testing using a soil box, include: foamed concrete with higher density has a higher compressive strength, thermal conductivity, and a lower porosity; to ensure the subgrade layer remains unfrozen, there is a minimum insulation thickness needed for a foamed concrete layer; increasing the depth of the insulation layer will achieve a better mechanical performance, while also increasing the frozen depth; and using a foamed concrete with a higher density results in a better mechanical performance.

Several questions were posed to Dr. Cheng after his presentation:

Q. What is the estimated design life with foamed concrete?
A. We did not check the timeframe of the pavement structure. We are currently working on lab tests to study the real traffic load on the pavement structure. A simulation could also be used.  This is something that we are currently working on.

Q. Were you able to find an optimal thickness and depth combination in this research?
A. We have some recommendations for the specific material used in this study. We have a design table that we can share for the foam concrete material but was not included in this presentation. We did a comparison among several insulation materials including foamed concrete, tire chips, foamed glass aggregates, and XPS board.

Q. Was the insulation box used to create the sample box replicated in the real life soil scenario?
A. We used XPS board around the sides to minimize heat transfer and to ensure heat transfer process in this test is vertical. In reality, the heat transfer in pavement is in the vertical direction.


Development of High Friction Surface Treatment Pre-screening Protocols and an Alternative Friction Application. Thomas Bennert, PhD, Rutgers University, Center for Advanced Infrastructure and Transportation (CAIT) Associate Research Professor

The use of HFST can improve surface friction in road pavements around curves to reduce lane departure crashes or on steep declines to improve braking. With HFST, hard angular stone is glued to the pavement surface in less than a ½ inch application. The aggregate of choice, calcined bauxite, is applied using epoxy. HFST must be applied to pavements in “good” or better condition (i.e. with no cracking or rutting).

Click for PDF

There can be situations where pavement appears to be in good condition, but is not a good candidate for HFST. In 2018, in studies on two county roads, overlays showed signs of premature deterioration, probably due to previously undetected issues. It was determined that a prescreening protocol was needed to determine substrate conditions before HFST is applied. The study developed an effective prescreening tool that assesses the compatibility of asphalt and epoxy. Field core samples would be used to evaluate pull-off strength and relative asphalt binder properties.

The study also explored High Friction Chip Seal as an alternative to HFST. In a case study, an asphalt-based binding system was shown to be more compatible with the pavement than epoxy resin. Aggregate from local sources proved to be an acceptable substitute and less expensive than bauxite.

Following the presentation, Dr. Bennert responded to questions asked through the chat feature:

Q. What is the life expectancy of HFST? Is it suitable for places with higher traffic volumes?
A. If a road carries high traffic volumes, it is probably designed without horizontal curves and steep declines that might require quick braking. Some areas in Pennsylvania and lower volume highways have used this application. Pavement life expectancy is debatable but generally depends more on the level of traffic volume than years in place. At around a million passes, pavement starts to show raveling, in part due to the effects of UV on epoxy, but aggregate also debonds. Applications can lose friction quickly, an aspect that we are concerned with for its safety implications as well.

Q. Is there any difference in the noise with HFST?
A. In applications using aggregates that point upwards, there is a slight increase in noise at the tire-pavement interface, similar to noise resulting from other microsurface applications in place around the state.

Q. Anything similar to high friction chip seal in use elsewhere in the country?
A. No. We were one of the first to consider this particular application. We worked with the asphalt binder supplier and did some laboratory work and looked at durability. Chip seals have been used in other areas of the country in areas where friction is an issue, but chip seals have not been specifically designed as a friction treatment as this one is.


Influence of Cracking and Brine Concentration on Corrosion and Chloride Content. Aaron Strand is a Ph.D. Candidate in the John A. Reif, Jr. Department of Civil & Environmental Engineering at New Jersey Institute of Technology and recently defended his Ph.D. Dissertation successfully.

Throughout the U.S., agencies are using increasing amounts of salt and brine to counter road icing. Corrosion is an expensive problem for highway bridges. In reinforced concrete bridges, the primary cause of deterioration is chloride-induced corrosion. The focus of this study was the effect of surface-applied chlorides through road salting, typically using rock salt or brine. The research showed that the effect varies dependent on the condition of the bridge deck.

Click for PDF

The research explored whether current testing takes into consideration the amount of salt placed on the roads, salt placement cycles, and the current condition of the bridge deck. Chlorides can affect the bridge steel reinforcement through diffusion from the surface, and through cracks in the bridge deck. The variables explored were salt brine concentration and degree of cracking and their effect on the corrosion time of bridge decks. Testing was undertaken in the lab and from core samples from a large-scale bridge deck specimen.

Ongoing work based on this preliminary study includes testing of other concrete mixture designs, testing other rebar types, and developing a model for the amount of chloride content and corrosion current process. Looking at other concrete designs.

Mr. Strand answered several questions following his presentation:

Q. Among the cracked samples, did the higher brine solution show faster corrosion? What was the rate?
A. They all really showed corrosion immediately, at least in the macrocell test, but the rate was not shown. Going back to the total corrosion, six percent showed a quicker rate, but the other three passed the threshold at the half-year mark. There might be a decrease in the time to corrosion as the brine is increased, but it’s maybe not as much as would be expected from such an increase.

Q. Did you introduce temperature as a variable or do you see this as part of a future study?
A. This would be part of a future study. We did look at doing some type of freeze-thaw work on the concrete itself, but not as part of the brine cycling. As part of research into different mixture design, we would look into temperature’s role into the rate of ingress.

Q. How would you like to see your research findings used to inform bridge design, operations or maintenance in the future?
A. The testing we do shows how mixtures might perform together. For actual application-based work, we need to be more careful about the testing of the materials. For example, we know very little about how incorporating changes is in brine concentration might impact corrosion.

Exploring Strategic Workforce Development in NJ: An Interview with the IUOE Local 825

FHWA is promoting Strategic Workforce Development in highway maintenance, construction and operations.

FHWA promotes Strategic Workforce Development in highway maintenance, construction and operations.

Strategic Workforce Development, an FHWA Every Day Counts (EDC) Round 6 innovative initiative, anticipates collaboration between government agencies, trade organizations, private agencies and communities to prepare individuals for the construction workforce. The demand for workers in highway maintenance, construction and operations is growing, as is the demand for new skill sets required for work with emerging technologies. An important element of this initiative is the recruitment and retention of women and minorities in the construction sector.  Through on-the-job training and supportive services program, NJDOT is exploring ways to work with contractors, contracting associations, and unions on shaping their future workforces, including programs aimed at increasing representation of women, minorities, and other disadvantaged populations in the construction and operations workforce.

We spoke with Greg Lalevee, Business Manager, International Union of Operating Engineers (IUOE) Local 825.  The organization is collaborating with Hudson County Community College (HCCC) on a newly established apprenticeship program and is undertaking other IUOE initiatives focused on workforce development in highway construction and related fields.

Background

Q. Can you tell us a little about your role with the union?

I am the Business Manager for the International Union of Operating Engineers (IUOE) Local 825. The jurisdiction of IUOE Local 825 is the State of New Jersey and the Hudson Valley (Rockland, Ulster, Sullivan, Orange, and Delaware Counties). We are heavy equipment operators, working on buildings, bridges, roadways, ports, airports, utility infrastructure, power generation, and reservoirs around the state such as Round Valley, Spruce Run, and Mercer Lake that ensure our water supply and serve for passive recreation. There isn’t much that an ordinary person does that operating engineers did not have something to do with. We have a 61-acre training center at exit 8A on the NJ Turnpike and a 51-acre training center in the Hudson Valley. I am also one of the vice-presidents for IUOE International, which covers the US and Canada.

Union members are engaged in many kinds of work using heavy equipment, including highway and bridge construction.

Q. Overall, what professions does IUOE support?

Aside from heavy equipment operators, our members do construction layout and surveying for infrastructure projects. Several members work as mechanics/product support for machinery product lines including Caterpillar, Deere, and Komatsu.

Q. Before we delve into your new IUOE program with Hudson County Community College (HCCC), please tell us, based on your experience, if there is a lack of awareness– especially among women and minority persons – for jobs/careers in the highway construction industry?

The lack of awareness for construction careers reflects a multi-tiered situation. In contrast to those residing in more rural areas, prospective job candidates residing in urban areas typically live “vertically” in high-rises and thus are familiar with professions including plumbers and electricians but not so much the work of operating engineers. They are not typically exposed to professions utilizing heavy machinery.

For the last seven years, I have reached out to political and community leaders in several NJ cities to try to develop a direct-entry program that would bring training opportunities to those communities for jobs that are semi-skilled or lower-skilled. The goal was to work collaboratively with community leaders to create a pipeline for young people to enter the workforce as operating engineers. To operate heavy equipment, one needs hands-on training. Our training facility is on the Turnpike in Middlesex County, which is difficult to access for anyone without a car. In one city, we proposed that we set up basic courses, including OSHA 30-hour construction training and Hazardous Material training, in a school, or faith-based or community center, and we would send an instructor. The participants would be working locally during this time, earning money and accruing benefits. When the trainees had acquired some basic training we would then send the simulator to that location and these individuals could start to acquire hands-on training. After 18-24 months of paid training, they may be able to purchase a vehicle and thereby access the training center. Or we might be able to partner with a faith-based or community center to work out a transportation plan for those facing transport obstacles. I proposed this concept in four NJ cities but, frustratingly, did not receive any positive responses.

Q. Several commonly cited roadblocks to entry into the construction sector, particularly for women and minority candidates, include transportation issues and childcare. What strategies could help to address these issues?

Both transportation and childcare issues can be roadblocks to entry into the construction sector. One of the reasons we pursued the NJ PLACE 2.0 grant with a higher education partner was to open the door to Pell grants to underwrite transportation or childcare costs through existing grant funding opportunities that a traditional union apprenticeship would not be eligible. In the past year we received accreditation as a standalone licensed technical college to help us open the doors to more job candidates. As we pursue programs in higher education, we can now take advantage of not only NJ Department of Labor grants, but NJ Department of Education grants as well.

Q. Do you see a role for unions like IUOE in helping to reduce barriers for women, minorities, and others in entering the highway construction trades?

Recently, the Operating Engineers fought to have highway construction work be subject to project labor agreements (PLAs). When it was written twenty years ago, the original legislation exempted this field from these agreements. We retooled the legislation to include much more aggressive percentages of women and minorities required on projects and helped to secure its passage by the legislature. These percentages now apply to any construction project with a value of $5M or more. However, since the law was passed and signed by the Governor in April 2021, the State has not used a PLA on any project.

Participation numbers for female and minority employees on these publicly-funded highway projects are generally set on a county-by-county basis by NJDOT. One of the reasons we strongly support inclusion in PLA is because when our contractors secure a publicly-funded highway job, they often contact IUOE to request our assistance in reaching these goals. We respond affirmatively, but when we offer to help with this recruitment, follow-up from contractors is not forthcoming. The reason is that these participation numbers are goals, not mandates and it would be difficult to make them mandates.

There is a false perception that unions don’t have their doors open to all, and that there is not equity or diversity amongst the ranks. We actively recruit people from the non-union world. However, in the 21 years since I was hired by IUOE, we have only encountered two men of color and one woman working non-union jobs operating heavy equipment. There are few women and minorities working non-union operating equipment; it seems that there is not a real draw to this occupation. So the issue is broader than just the unions.

About five years ago, the number of paving projects in the State was increasing and we saw that our front line paving operators were aging. To address demand, we recruited 36 candidates to join a full-immersion paving training initiative. With paving shut down for the winter, we were able to hire and bring in seasoned major paving contractors as instructors during their off-season. The participants were instructed on one piece of paving equipment for 14-weeks until we knew they could run it proficiently. They were then absorbed by the paving industry for high-paying work during the summer and were brought back each winter over a five-year period to learn another piece of paving equipment. It’s not an apprenticeship program so we were not bound by apprentice rules, but we were able to train a diverse group. Of the 36, over one-third were minorities and women, and one-third were veterans. None of these people were associated with our union. In all, while the paving industry is unique, and our training school had the capacity to respond to this particular need, it represents an example of how thinking outside the box and proactively recruiting targeted groups can be very successful.

Q. We have heard that pre-apprenticeship programs are growing in popularity across the country. Are you aware of any pre-apprenticeship programs for the highway construction trades in NJ?

Pre-apprenticeship programs are not growing in the highway construction trades, but are happening in the building trades. I have concerns though with the pre-apprenticeship programs that I am aware of. For example, some pre-apprenticeship programs offer testing help that provide individuals with tutors to teach them how to pass the union apprenticeship written test. The percentage of these students who are actually admitted into the apprenticeship program does not appear to be that high however. Candidates are ranked by test score, so those that receive testing assistance might secure an interview, but they typically score lower in the written portion of the apprenticeship exam compared to their peers and thus do not advance. Overall, the competition for these positions is fierce.

IUOE Program with HCCC

Q. We know the Earn & Learn program orientation with Hudson County Community College was a few weeks ago [in January 2022]. How is program implementation going so far?

We understand that all 30 students are still enrolled and thriving. This cohort includes 10 minorities, 6 women, and 6 veterans so this is an opportunity to support diversity. For many of them, this is a continuation of their college education, and some are eager to pursue an occupation where they will earn $80-100,000 a year. The NJ PLACE 2.0 grant supports inclusion of a success coach to help keep the students on track, which is helpful. The students will be at our training center in May to begin traditional operating engineer training in the classroom and with equipment.

Q.Will all of your apprentices go through this program in the future, or are there multiple paths to a career in construction?

We have our own very competitive apprenticeship program with 160 people. There’s been a lot written about a skill gaps and a worker shortage. We want to develop a new apprenticeship model and have hired an academic who will begin working with us this spring to help develop some new apprenticeship tracks.

We have had a successful process for soliciting apprenticeship applicants in the last two traditional application cycles. There is a date and time when applications are available and the first 250 people in line receive one. The opportunity is posted on the Tuesday after Labor Day. We advertise in the paper and on social media. We have candidates lining up for a week ahead of time. For the Earn & Learn program with Hudson County Community College, the on-line application was opened and the portal had to be shut down in two hours due to the high response.

One gap we are eager to bridge is from the Vo-Tech programs to our apprenticeship program. Individuals have to be 18 years old and a high school graduate to enter an apprenticeship program, but some students are 17 when they graduate from Vo-Tech so we lose this cohort. We are trying to harmonize the end of Vo-Tech education with the beginning of an apprenticeship. Traditionally, our apprenticeship program begins in April. For the Earn & Learn program, we changed the start date to January to align with the academic calendar. Any changes to our apprenticeship programs must be approved by the federal government. Sometimes this process means that we can’t move as quickly as we would want.

People will tell me they can’t find workers, but we can get people; there is a lot of interest in our Operating Engineers apprenticeship program. Several of the other trade union apprenticeship programs are very competitive as well, including the Carpenters and the Ironworkers. The Carpenters union had an arrangement with East Brunswick Vo-Tech for direct entry to the union apprenticeship program for up to three students upon graduation from the carpentry program. The Vo-Tech sends students who are well-prepared and likely to succeed. I am trying to mirror that arrangement with Middlesex County Vo-Tech Career and Technical Education program.

Q. Do you see IUOE Local 825 collaborating with other institutions on similar programs in the future?

Absolutely and with multiple higher education partners and members of the business sector whom we have not yet identified. Hudson County Community College has a construction management program that offers 6-8 courses that build the “perfect operating engineer” and HCCC’s Lori Margolin and I are discussing how we could organize those courses together into a different type of degree program in the future. There are existing programs at other state education institutions that we have been considering as well. We might be able to take advantage of remote learning opportunities.

IUOE 825 will continue to look for opportunities to collaborate with HCCC and other higher education institutions.

IUOE 825 will continue to look for opportunities to collaborate with HCCC and other higher education institutions.

We are also very interested in the transportation-related activities at Rutgers-CAIT (Center for Advanced Infrastructure and Transportation) and testing on bridge work. Rowan University has ongoing asphalt research and recently visited the IUOE training center to see if they could use some of the area for asphalt testing and of course we would support that.

Every year, we have a full-immersion asphalt paving class. A major manufacturer of paving equipment has been visiting our site in the past week teaching our journeyworkers and apprentices about the latest technology on their equipment. We have the equipment dealer with the product support staff and mechanics participate and share the service bulletins and the new information. And the dealers get the word out to members of the broader construction community who can attend these events.

These are ways we will continue to collaborate with the educational world and the business world in the future. We can leverage our 8,000 members, 1,400 employers, 120 pieces of heavy equipment, and 61 acres in New Jersey and 51 acres in the Hudson Valley. We have the laboratory and want to establish synergies and diverse partnerships to support the industry.

As the burgeoning field of automation and robotics for heavy equipment grows, I sit on an IUOE International subcommittee where we are discussing the skill sets and training needed to prepare an individual to be a successful remote equipment operator or REO. We can work with the computer engineers to let them know what aspects of heavy equipment operation may not be transferable to computers and what alternatives there might be to support their efforts.

Looking Ahead

Q. What strategies should be pursued to encourage more New Jerseyans to consider a career in the construction industry? Who should be leading or involved in those efforts?

A key reason why our organization migrated toward the higher education piece is because we believe that we will secure a more diverse population of job candidates by doing so. Specifically, offering an avenue to earn an Associate’s degree is helping to increase awareness for construction and operating engineer careers.

Students in Somerset County’s MEAM program participated in an Operating Engineer Awareness program and IUOE’s training facility.

Moving forward, our long-term goal is to implement more of a college application process rather than continue the traditional apprentice application process.  We are also seeking partnerships with the Vo-Tech system since most of the traditional high schools do not have programs that align as well with our goals and needs.

I am on the Board of Somerset County Vo-Tech and my daughter is a guidance counselor at Middlesex County Vo-Tech so we know the system fairly well. We wanted to provide students from Somerset’s Mechatronics, Engineering and Advanced Manufacturing program (MEAM) an opportunity to learn about IUOE and visit our campus. In academic parlance, our program fits in the Advanced Manufacturing sector. I worked with the superintendent to secure a small grant for an Operating Engineer Awareness program at Somerset. We developed a curriculum to introduce the students interested in construction to the occupation of construction engineer, and transported the students to our campus to see and experience the equipment. We are also helping the district with OSHA training, and with welding, and are seeking other opportunities to work together. Ocean and Hunterdon Counties have Equipment Operator programs that are simulator-based but we have not yet received a lot of interest from them in working with us. East Brunswick Vo-Tech is very close to our campus and we have students visit from there as well.

Q. Through their on-the-job training and supportive services program, NJDOT is exploring ways to work with contractors, contracting associations, and unions on shaping their future workforces, by focusing on training and recruitment programs aimed at women, minorities, and others. Do you have any thoughts about how NJDOT might pursue this goal?

NJDOT should consider implementing several model project labor agreements, collaborating with the different trades, with all participants making a concerted effort to increase the number of women and minorities on a project. The outcome of this effort could be presented as a showcase and best practice example statewide. It is important to recognize that when we set the hiring goals to include a certain percentage of women and minorities, we have to plan to engage in a collaborative effort with the successful bidding contractor to reach those goals. Rather than penalize a contractor if they experience challenges in achieving the diversity goals, we need to determine strategies for how to reach them and secure their buy-in to reach these diversity goals.

Recently Issued TRB Publications and ASTM Standards

The NJDOT Research Library maintains a “Did You Know” page to share basic facts about the research library, transportation research resources, and newly issued publications.

The TRB Publications, January-February 2022 list includes recently published research in operations and traffic management, data information and technology, bridges and structures, pavements, bicycling and pedestrians, safety and human factors, and construction, among others.  The breadth of transportation research is on full display.  Recent papers cover such topics as unmanned aerials systems and bridge inspections; optimization modules for planning and programming of bridges; and safety and signal prioritization studies involving automated and connected vehicles; among other topics in this 125+ publication list.

One paper that caught our eye, "Enhanced Spatial–Temporal Map-Based Video Analytic Platform and Its Local- Versus Cloud-Based Deployment with Regional 511 Camera Network", explores the cloud- versus server-based deployment scenarios of an enhanced computer vision platform for potential deployment on low-resolution 511 traffic video streams.  The model evaluation described in the paper used videos from multiple cameras from the New Jersey Department of Transportation’s 511 traffic video surveillance system.

The ASTM Standards, September to December, 2021 list includes recently proposed and revised ASTM standards. The ASTM Book of Standards is available through the ASTM COMPASS Portal for NJDOT employees.
