A city’s construction casts an indelible mark on how its citizens perceive it. Everything from the size and concentration of buildings to the confluence of roads to the allotment of green space helps inform the look and feel of a place.

Ultimately, city leaders, developers, architects and contractors must work together to strike a balance between the form and function of man-made infrastructure and a town’s natural landscape. Sometimes function wins out.

Such was the case with the construction of the Alaskan Way Viaduct.

The Alaskan Way Viaduct was an elevated double-deck highway in downtown Seattle that was built in the 1950s to help solve the area’s growing traffic problem. While the two-mile-long structure helped relieve congestion, becoming one of the state’s busiest sections of highway and carrying 110,000 cars per day by the end of the 20th century, it doubled as a waterfront obstruction shielding residents and workers from nearby Elliott Bay.

Then, in February 2001, a 6.8 magnitude earthquake hit the city. After engineers assessed the damage, it was concluded that the highway could be susceptible to collapse in the event of a similar event in the future. Fearing the catastrophic repercussions of such an event, city leaders embarked on a years’ long quest to find an alternative way for citizens to get in and out of the city.

In January 2009, city officials came up with a plan. In the summer of 2011, it was made official: Crews would construct the world’s largest-diameter bored tunnel beneath downtown Seattle. Although the viaduct remained in operation throughout the tunnel’s construction, after it opened in February 2019, the stage was set to begin restoring the city’s waterfront via the highway’s demolition.

The task at hand

Kiewit Infrastructure West Co., Omaha, Nebraska, was selected as the contractor on the project, with Newark, California-based Ferma Corp. being selected as the lone demolition subcontractor in July 2018.

According to Ferma Corp. National Projects Division Manager Kelly Arnold, who oversaw the viaduct demolition, a substantial amount of planning was required on the front end of the project to formulate the team’s strategy.

“Ferma Corp.’s scope of work involved the complete demolition and removal of 1.5 miles of raised highway in the form of a six-story double-deck bridge. As is the case on all of Ferma’s projects, significant pre-project engineering and planning took place before we stepped on-site,” Arnold says. “First, our estimating team set up a high-level schedule incorporating each phase of the project to coordinate our efforts with those of the other contractors on-site. Next, we created a site-specific health and safety plan (SSHASP) and combined this with a demolition work plan specific to this project. … This document provided a template for safety and demolition operations specific to each area and task for the project. The SSHASP/demolition work plan took into consideration the necessary safety, personnel, equipment and material resources in order to perform the project safely and to meet or exceed our schedule. Every single task we performed was designed in advance of our demolition operations and communicated to personnel before the project commenced. This communication was repeated on a daily basis throughout the course of the project.”

After months of due diligence, viaduct removal work began on Feb. 12, 2019. The Ferma Corp. team, which totaled 12 on-site contractors, started with the upper deck of the highway, punching out the roadway between the girders. At parts where the highway was especially close to nearby buildings, contractors would saw-cut girders and lift them out with the help of cranes. Once the roadway between the girders and the girders themselves were removed, an excavator was then used to remove the columns and crossbeams. After the top deck was completed, Ferma Corp. started with the lower deck and removing the footing.

Arnold says Ferma Corp. utilized a range of company-owned equipment for the project. For the upper deck of the highway, he says the company mainly utilized a 108,000-pound Ferma FE50 demolition excavator with a 13,000-pound LaBounty MDP50R rotating processor.

For the lower decks, because of the restricted overhead clearance, they utilized a smaller Volvo EC220EL excavator equipped with a LaBounty MDP27R processor to wreck the girders and a LaBounty LMB 4035 8,000-pound hammer to slot the deck.

Specifically for wrecking girders, bents and columns, the company utilized a 420,000-pound Ferma-customized FE200 demolition excavator with a 35,000-pound LaBounty UPX1800 rotating processor and a 260,000-pound Ferma-customized FE115 demolition excavator with a 22,000-pound LaBounty UPX950 rotation processor.

To round out the work, Arnold says the team utilized a fleet of 16 additional excavators to perform multiple functions across the project.

Close quarters

Some parts of the Alaskan Way Viaduct were located within feet of adjacent buildings. This proximity required a concerted effort by Ferma Corp. to mitigate disruption to nearby people, property and businesses.

“I’ve been in the demolition business for 32 years, and this is one of the toughest jobs I’ve ever done,” Arnold says. “The most difficult aspect of the job from a demolition standpoint was its proximity to people, traffic and buildings. Demolition is an inherently dangerous field. This project posed significantly more difficulty due to all of these factors, each of which caused the project difficulty level to increase exponentially.”

According to Arnold, the close distance of the buildings to the highway helped inform Ferma’s every move. He says that his team had to adopt a measured, methodical approach to avoid complications and lessen the disruption to area businesses. This was facilitated by detailed coordination with Ferma’s engineering department and the project’s engineering partner, Las Vegas-based Sigma Engineering Solutions. The company also incorporated additional safeguards on the project such as hanging curtains to catch fly rock and wrapping the hammer attachments with rubber to keep dust down and prevent other flying debris. This made for a cleaner working environment and less disturbance to those living and working in the area.

Above all, Arnold says having such little room for error required the Ferma Corp. team to be fastidious about proper communication.

“Communication is key on every project, but even more so on this project.” Arnold says. “We consistently utilized many types of communication, including written, verbal, radio, direct line of sight and hand signals. These communication methods are achieved through a formal communication chain requiring clear, concise and timely messages; utilizing the appropriate platform; and [ensuring] the effective use of technology.”

Recycling right

A job the magnitude of the Alaskan Way Viaduct comes with a substantial volume of materials to process. Arnold says his team worked as quick as possible to sequester this material upon demolition so cleanup crews could make easy work of transporting it off-site.

“There was so much material, you couldn’t haul it out fast enough. You had to get it flattened and leveled out so you could work and then the cleanup crew would come in behind [and take it away],” he says.

Arnold says Ferma Corp. was able to recycle 100 percent of the demolished material on this project, which included more than 5,000 tons of rebar, 500 tons of steel and 120,000 tons of concrete. The steel, iron and metal were all recycled for beneficial reuse, while the concrete was crushed and utilized in the backfilling of the underground tunnel as per project specs.

Making way for change

After 10 months on-site, Ferma Corp. completed demolition work in December 2019. Arnold says that factoring in the baseline contract schedule plus changes made to the project post bid, his team was able to complete the project on time and within budget.

More importantly, according to Arnold, is the fact that the job went off without a hitch from a safety perspective.

“There is nothing more important than community safety, job site safety and the safety of our people,” he says. “One of the reasons Ferma Corp. was selected for this project is our historically strong safety program and subsequent results.”

Ferma Corp.’s commitment to safety and avoiding disturbances in the city did not go unnoticed, Arnold says.

“One of the most rewarding things is just seeing the public watching us work. We hear a lot of good [feedback] from the public, and you see some of the tenants up in these buildings put up big signs [encouraging our workers], it’s really nice,” he says. “Every project has its inherent rewards, but with this project in particular, it was pretty amazing to watch the Seattle community come together as one. As difficult a project as it was to perform, to see the response from the local community has been very rewarding.”

Arnold says this feedback, along with the overwhelmingly positive response they’ve gotten from helping restore the beauty of downtown Seattle, made tackling the project a rewarding experience for all of the Ferma Corp. team.

“Ferma Corp. is proud to have been part of this historic teardown project,” he says. “To have performed such a project without incident is a monumental feat. [We’re] making history here. [We’re] changing skylines forever. When you hear the [positive feedback], and people actually appreciate what you’re doing and they see you’re really just trying to beautify the city, that’s what it’s all about.”

Winter and early spring is show season for the construction, demolition and recycling industries this year. Two of the biggest shows for industry professionals are the National Demolition Association’s Demolition Austin event taking place Feb. 22-25 in Austin, Texas, and the Association of Equipment Manufacturers’ (AEM) CONEXPO-CON/AGG taking place March 10-14 in Las Vegas.

Construction & Demolition Recycling (C&DR) spoke with Sandra Mason, public relations director of the AEM and Jayne Corso, marketing and communications director of NDA, about what attendees can expect from the show.

All about Demolition Austin

C&DR: What’s new at this year’s show?

Corso: We are excited about a few new events and education opportunities that we are offering at Demolition Austin in 2020.

During our pre-convention programming, we are offering a new course, the Demolition Superintendent Bootcamp, on Feb. 21. This course is targeted towards the superintendent, foreman or site-supervisor level and includes a second day of hands-on experience at the Live DEMOlition location.

Speaking of which, we are bringing back the Live DEMOlition event for its third year on Feb. 23. This event continues to be a hit year over year. This year, we will be bringing back the obstacle course competition where attendees can test their skills and abilities against others on a skid steer, mini-excavator, and a remote-control demolition machine. This obstacle course will be part of NDA’s fundraising efforts at Demolition Austin, in addition to the cornhole tournament and chicken bingo events that will be happening at the expo’s opening reception and “Toast to Texas” event, respectively.

We are also introducing the Mike Casbon Safety Award, honoring the legacy of the late Mike Casbon, this year. An expert with 25 years of experience in the fields of demolition, decontamination and construction, Mike was a member of NDA’s Education Committee, Safety Committee and Government Affairs Committee. Mike was instrumental in the development of NDA’s Foundations of Demolition Management education series, and posthumously received NDA’s Hall of Fame Award in 2019. In addition to his contributions to the NDA, he was also a subject matter expert for the OSHA Training Institute (OTI) and had trained more than 1,000 compliance officers on field inspection principles.

C&DR: How are you looking to build off last year’s show?

Corso: We are hoping to build off the momentum of last year’s show, specifically with the success of the Live DEMOlition event. This year, we are expecting to expand to 16 to 18 participating companies total, building off the 14 we had last year. In its second year, the event grew to almost 700 attendees and became an all-day event. Registration for the Live DEMOlition Event is included as part of the full Demolition Austin registration. With this large attendance, we are looking to bring new exhibitors to the Expo.

In terms of education, OSHA is returning to this year’s show to speak on the top 10 violations seen in the demolition industry and on regulatory updates for construction that apply to demolition. OSHA’s session has always been a popular topic for our attendees.

C&DR: The show is back in Austin. Why is this a good location for the event?

Corso: Austin is a great location because it is a central point for demolition professionals around the country. Members voiced that they liked the location, as it’s a fun, easily accessible city in the U.S. Also, outside of California, Texas has the largest concentration of NDA members, so it makes sense from that perspective, as well.

Austin gives us the opportunitiy to take advantage of new hotel properties, as well as expansive expo and Live DEMOlition space. The Texas Disposal Systems (TDS) has been a great partner with NDA and you can’t beat their venue for the Live DEMOlition—their exotic game ranch is family-friendly and their large property is a perfect fit for our growing event.

C&DR: For those who are unfamiliar, can you talk about what the Fast and Furious education sessions will offer?

Corso: Fast and Furious presentations are 15-minute education sessions focused on a variety of industry topics. This year, topics include an update on the scrap market, how structural engineering can benefit the demolition industry, and other best practices to improve business. Fast and Furious presentations are always popular with attendees because they provide quick insights into today’s demolition hot topics and create opportunities for questions and further exploration.

C&DR: Now in its third year, how have you seen the Live DEMOlition Event benefit attendees and why is the event a great opportunity for contractors?

Corso: The Live DEMOlition event offers attendees the opportunity to talk to vendors in person about their equipment and test drive machines before purchasing. It also gives our attendees and vendors an opportunity to connect and build stronger relationships outside of the traditional expo setting.

The event continues to grow, and attendees and exhibitors alike have raved about the opportunity to network and test equipment all in one location. Once again, attendees will have the opportunity to test excavators, dust suppression equipment, hydraulic attachments and more at this full-day event.

Plus, we are inviting our attendees and their families to take advantage of the TDS’s exotic game ranch animal tours, which will be scheduled throughout the day.

C&DR: What kind of networking opportunities do you have planned at the show?

Corso: In addition to the expo opening and welcome receptions, we will be hosting a Local Brews Beer Reception on Feb. 24 that will feature local breweries and provide attendees time to network with exhibitors and peers alike.

Plus, we’re looking forward to our Toast to Texas offsite reception. The reception will include outdoor games and chicken bingo—a game made famous at Ginny’s Little Longhorn in Austin.

The NDA Awards Banquet will recognize trailblazers and rising professionals in the demolition industry through the presentation of the NDA Lifetime Achievement Award, Excellence in Demolition Awards, Scholarship Awards, Hall of Fame Awards, and the new Mike Casbon Safety Award.

C&DR: Anything else to note?

Corso: We are excited to welcome this year’s keynote speaker, Seth Mattison. Seth is an internationally renowned expert, author and futurist. As founder and Chief Movement Officer of Luminate Labs, Seth advises many of the world’s leading brands and organizations on the key shifts happening around talent management, change and innovation, leadership, and the future of work. During the keynote address, Seth will be sharing insights on how to manage a team and establish strong leadership roles.

What to expect from CONEXPO-CON/AGG

C&DR: What’s new at this year’s show?

Mason: The show is expanding its 2020 footprint to include the Las Vegas Festival Grounds, located on the Las Vegas Strip adjacent to the Circus Circus Hotel. Types of exhibits in the Festival Grounds will include aerial and cranes, earth moving, hauling and underground construction.

The 2020 show connected campus will also include new and expanded transportation, attendee experiences and registration locations. Features will include multi-site drop-off locations for shuttles, complimentary monorail passes, golf cart shuttles, and various experiential transportation options to accommodate for the attendees throughout the week.

Also new for 2020 is the opportunity to mix and match education sessions between CONEXPO-CON/AGG and the International Fluid Power Exposition (IFPE) for one price.

CONEXPO-CON/AGG will also feature the new AEM Workforce Solution Area at the trade show. The Workforce Solutions Area will invite the CONEXPO-CON/AGG show attendees and exhibitors along with association members, job seekers and local students to experience and learn about a trade right on the show floor. In addition, participants will learn about the industry and take away best practices from what will be an interactive workforce pavilion.

C&DR: Technology is increasingly influencing construction. How will the show reflect that?

Mason: In 2020, we have set up a Tech Experience that will explore three key areas that will transform the contractor’s business in the future: modern mobility, sustainability and smart cities.

Today’s global infrastructure cannot sustain the expected future growth in vehicle traffic. The Modern Mobility sessions at the CONEXPO-CON/AGG Tech Experience will focus on the transformation of current systems for moving people and products to meet tomorrow’s demands.

Housing, workspace, infrastructure and utilities all have serious social and environmental consequences. The Sustainability sessions at the CONEXPO-CON/AGG Tech Experience will tackle building, vehicle and civil design with renewable energy, recyclable construction materials, and economic and environmental impact in mind.

Contractors and surveyors will also need to be aware of new technology and how it affects job sites as cities aim to become smarter globally. The Smart Cities sessions at the CONEXPO-CON/AGG Tech Experience will explore how urban centers can incorporate digital data collection and processing to efficiently manage everything from power transmission to law enforcement to waste management.

A 10- by 22-foot smart city replica will also be on display. This replica will help demonstrate how a smart city, through sensors and analytics, will be able to transform information into digestible data and provide knowledge for the city and its people to work smarter.

The Tech Experience will also feature the 3D printing of an entire house and showcase how an 18-mile stretch of interstate highway in Georgia is becoming a solar energy proving ground.

Ultimately, our goal for the Tech Experience is to show contractors how these new technologies will impact their current work, how the expectations and demands of customers will change and how the current state of infrastructure may change.

Additionally, Tech Talks will be featured throughout the week featuring sessions such as: Driving Decisions with AI, the Design and Print of Future Structures, Rebuilding Better for Resiliency, and Creating the Highway of the Future.

C&DR: This year’s show features Highlighting Women Events. What will these encompass?

Mason: To highlight women as a viable force of the construction industry, CONEXPO-CON/AGG has teamed up with The National Association of Women in Construction (NAWIC) and Women of Asphalt (WOFA).

Together, CONEXPO-CON/AGG, NAWIC and WOFA are seeking to draw attention to and celebrate the important role women play in the industry. Throughout CONEXPO-CON/AGG 2020, they will not only showcase women industry leaders, but reinforce the career growth potential for women, who today represent a small percentage of the workforce and the opportunity to diversify the industry.

These three organizations are pooling their collective influence to sponsor and engage in education and other events at the show. They will kick things off on March 11 with a breakfast event, “Genders on the Job Site.” Two special guests for the event, Vicki O’Leary, founder of Be That One Guy and Lorein Barlow, director and producer of Hard Hatted Women, plan to have a candid discussion on how women experience job site opportunities and challenges and explore how everyone has a role in keeping job sites productive and safe for all workers.

Other events include:

• Widening Your Workforce: Executive Lunch Forum
New Approaches to Building Female Construction Leaders
• Gain a Competitive Advantage Through Construction Technology
• Attracting and Training Your Workforce: Operating Engineers’ Innovative Solutions

C&DR: What kind of networking opportunities do you have planned?

Mason: IFPE will be hosting a special networking reception for engineers and executives for the first time. The IFPE’s Fluid Power Hour, presented by Bosch Rexroth, will be held on March 11 from 4 p.m. to 6 p.m. on the IFPE show floor. The event includes a bonus hour on the IFPE show floor, complimentary hors ‘d oeuvres and cocktails and entertainment.

There will also be a social media influencer panel discussion and networking event in the Tech Experience featuring construction business owner Missy Scherber who will be joined by influencers including Aaron Witt of BuildWitt, Keaton Turner of Turner Mining Group and Stacey Tompkins of Tompkins Excavating. The group will answer attendee questions on using social media to recruit new hires, developing corporate values and culture, taking your marketing to the next level, and the changing face of the construction industry.

While guilt by association is a familiar concept, in the case of nonferrous scrap, it’s more like uplift by association. An increase in ferrous scrap pricing and flow that began in the fourth quarter of 2019 has benefitted a number of nonferrous scrap grades heading into 2020.

After declining throughout much of 2019, ferrous scrap prices increased by about $20 per ton on average in the U.S. in the November 2019 buying period and by another $30 per ton in the December buying period. This upward momentum continued into the January buying period, which also saw a pricing increase by $30 per ton generally, according to Fastmarkets AMM’s surveyed pricing.

No. 1 heavy copper and wire scrap was selling for $2.19 per pound on average as of early January, while No. 2 heavy copper and wire scrap was selling for $2 per pound, according to surveyed pricing from Fastmarkets AMM. This compares with an average U.S. price of roughly $1.95 per pound for No. 1 heavy copper and wire and $1.82 per pound for No. 2 heavy copper and wire in the December 2019 buying period.

Painted aluminum siding was selling for 25 cents per pound in the January buying period compared with roughly 20 cents per pound in December 2019, according to Fastmarkets AMM surveyed pricing.

Despite the relatively mild start to the winter season in the Midwest and the higher prices, a nonferrous scrap trader based in that region says nonferrous scrap remains in short supply though flow has improved somewhat.

Better movement

“Flows are picking up across the board,” says a nonferrous scrap trader with a company that has processing operations in the Southwest. He attributes that to the “excitement” created by the increase in ferrous scrap pricing, which helps to bring nonferrous scrap into the yards.

“There is an increase in quoting as well as flows,” the Southwest-based trader says of the nonferrous scrap sector. “It’s changed a little compared with the fourth quarter. Things were relatively slow in generation as well as in consumption.”

Copper has benefited somewhat more from the uptick, the contact in the Southwest says. “Relative to aluminum, copper is in a better position with better balance in the domestic market. Aluminum is still pretty out of balance.”

His company primarily handles postindustrial scrap as well as material from other scrap dealers in the region.

“Demand is slightly better, depending on the commodity,” says the nonferrous scrap trader based in the Midwest. His company has scrap processing operations throughout the region. “Export is much better,” he adds, “and prices have bounced off their lows for most nonferrous commodities.”

In terms of domestic generation, the source in the Midwest says it is “decent but not great” for copper, adding that buying material was difficult when COMEX pricing dropped to the $2.60 per pound range toward the end of last summer. COMEX copper pricing increased to the $2.80 per pound range on the news of the U.S. and China reaching an agreement on Phase One of a trade agreement in December of last year. The Midwest-based trader says that if COMEX pricing stays near the $2.80 level, it could help to bring out additional copper scrap. However, he adds, “Some people are always waiting for the next big move.”

“Spreads for bare bright No. 2 are wider than based on the available material,” says the source in the Midwest. “I think that will change as consumers get back into the swing of things.”

He says aluminum generation also has slowed, adding that secondary producers and primary mills realize this is the case. “Three to six months ago, they could buy whatever they wanted whenever they wanted,” the Midwest trader says. “Now, they are paying a premium for spot material.

“Six months ago, everyone was in the same boat,” he says of aluminum scrap consumers. “Today, one consumer might be short on tweak or turnings.”

A copper scrap processor who wants to remain anonymous says that while demand has picked up somewhat, domestic consumers are still measured in terms of their buying and will be for the next few months. “They are not aggressive in their purchasing yet. Demand is still slow in terms of what their needs are for 2020.”

He adds, “Pricing has stabilized, but spreads are still fairly wide in that it is a buyer’s market.”

Despite the recent pickup in the nonferrous scrap sector, Todd Safran of Safran Metals Inc., a nonferrous scrap processing company based in Chicago, says, “Things aren’t getting any easier, but you have to continue to find your niche and ride out this roller coaster.”

Overseas interest

The Midwest-based trader characterizes supply and demand for copper as being in “pretty good balance,” adding that the export market has helped to pull some material out of the U.S. that normally stays in the country, such as Nos. 1 and 2 copper.

The trader based in the Southwest agrees with this assessment. His company is exporting copper scrap, particularly in the form of birch/cliff (No. 2 copper wire/No. 2 copper solids and tubing) to countries in Southeast Asia, Asia and Europe. “They are buying at a very healthy spread, which tells you that even with the tariff, there is just good demand,” he says.

He says Chinese buyers are buying material with the highest copper content they can in light of the tariffs China is assessing on copper scrap shipments from the U.S.

“If you look at brass, export is really depressed because the tariff is too taxing,” he adds.

Aluminum scrap is not enjoying the same interest from export markets, however. “Everything globally is tough right now,” the Southwest-based trader says. “Asia, specifically Korea, is swamped with aluminum.”

While export demand is off compared with the years when China dominated buying, Safran says it has been increasing for the last couple of months. “I won’t say it’s setting the world on fire, but I am seeing it come back to life a little.”

A nonferrous scrap broker based in the Southeast says the quotas the Chinese government issued for nonferrous metals imports in the first quarter are “surprisingly generous.”

The country permitted an additional 26,566 metric tons of copper scrap, 7,544 metric tons of aluminum scrap and 3,180 metric tons of steel scrap to enter China in the first quarter in a second batch of quotas issued in early January. The first batch of quotas for the quarter was announced in late December 2019. In that batch, nearly 271,000 metric tons of high-grade copper scrap and nearly 275,500 metric tons of aluminum scrap quotas were issued.

The broker adds that “some consumers think it may be a gesture of the U.S.-China trade war standing down or maybe Beijing just beginning to realize the importance of scrap.”

Additionally, the Chinese central government has announced that as of the second quarter of this year, high-grade copper and aluminum scrap that meets new purity standards will no longer be classed as waste and can be imported into the country in unlimited amounts.

Despite the unexpectedly generous quotas from China, Safran says U.S. scrap processors must “get as creative as possible and forge new relationships” to keep material moving.

“If you have a great product and great relationships, you’re going to be able to find good homes [for material],” he says. “We are playing the long game.”

Predictions for the year ahead

Most of the sources contacted for this article say they are “cautiously optimistic” about the outlook for copper and aluminum scrap in the year ahead.

However, a second broker based in the Southeast speculates that 2020 will not be a good year for aluminum scrap. He says the notion that aluminum scrap pricing found the floor in December was wishful thinking on the part of suppliers, as a limited number of mills need material.

Regarding the tentative optimism he was feeling in early January, the trader based in the Midwest adds that it could “go away in the blink of an eye” because of the lack of visibility that characterizes the business today and the geopolitical forces that have been shaping the nonferrous scrap sector, including tariffs and trade wars and the potential for actual war in the Middle East.

Safran says he thinks the first quarter of the year will offer more of the same, though he is hoping for increased activity in March and April. “We need to give it a few months for the system to flush itself out,” he says. “I think there will be a better outlook for the next three quarters of the year.

“Things are happening [trending] to the positive,” he adds.

“There is a brighter path ahead,” the Southwest-based trader says. “We are not out of it yet, but there is excitement, movement and flow.

“I don’t think we are over the hump,” he continues. “It still is a difficult marketplace, but it is a little better than in the fourth quarter.”
