Framing that delivered an all-round vision within tight timeframes. When this distinctive circular designed school required completion for the start of the academic year, light gauge steel framing made from TRUECORE® steel delivered. Prefabricated and then assembled on site, impressively large roof truss and frame modules were craned to height, then safely and eciently installed into their elevated positions. The end result is a state-of-the-art learning space designed in the round and produced on time.

“You walked into that club and it smelled like show business” – Jerry Seinfeld In this issue, we feature and celebrate 2021's Rising Stars. They are our industry colleagues under the age of 40 who have distinguished themselves technically, led teams, delivered great projects, and given back to their professions and communities. All were nominated by the firms in which they work. Please take a few minutes to read their amazing stories. Catch a Rising Star (CaRS) was one of the first comedy clubs in New York City. Founded in 1972 by Rick Newman, it launched the careers of an astounding number of comics. Many turned into stars and then exploded into supernova – including Robin Williams, Billy Crystal, Elayne Boozler, Chris Rock – and Jerry Seinfeld. The early history of CaRS is a case study in creating and nurturing talent. 1. Be a place that is of its time. CaRS vibrated on a different frequency. It ran one continuous show that lasted late into the night. And in the words of Newman “You weren’t watching your father’s comedians on the Ed Sullivan Show.” The club spoke to a new generation. Does your firm do the same? Are you maximizing the potential of technology? Do you offer contemporary benefits like flexible work options, parental leave, and wellness benefits? Does your firm “give back” and do you encourage your staff to do the same? 2. Offer opportunities to try new material. Mondays – the slowest day of the week at CaRS - became Audition Night. Up and comers performed their sets during the week. It was a safe place to try new material and learn from a live audience. Are you offering your team similar opportunities to innovate and learn? 3. Coach and Mentor. David Brenner was an established comic when he walked through CaRS’s door in 1972. He gave the club legitimacy and star power. He was also generous with his time. Brenner coached up the comics who were going to perform on The Tonight Show for the first time. And he and other veteran comics held late night ses- sions with the younger talent where career advice, lessons learned, and war stories were served up. At Zweig Group, our mission is to Elevate the Industry. The profession of engineering is no joke, and we don’t advise clients on scent. But when you elevate your firm and its culture, you create space above for your own rising stars to shine.

july 2021


“By 2025, millennials will make up 75 percent of the workforce.” Whether accurate or not, (the number was recently challenged but remained widely accepted to be fact), we have all read or heard this statement at some point in the last few years. This number has driven plenty of workplace articles, each of which drawing a differ- ent prediction or sentiment of what that means to their respective target audience. And today, it’s my turn. As someone born in the early 80s, and blessed (or cursed, especially in terms of career advancement) with a very youthful appearance and “vibe,” I personally cannot wait for my generation to rise to power, and take over the world figuratively and literally. I have worked most of my association and marketing career supporting and betting on young professionals and emerging leaders. I have made it my personal mission to advocate for this group whenever I have the opportunity to. I have shoved and pushed my way to the room (sometimes I am fortunate enough to have an actual seat at the table) just so I could be the person in that room or at that table to throw an emerging professional’s name in the hat – be it a speaking opportunity, a nomination for an award, a publishing opportunity, their name on a project, or a promotion; I strive to be these bright young stars’ advocate. I have worked closely alongside plenty of brilliant millennials in AEC and beyond, who are resourceful, social- ly conscious, efficient, adventurous, and incredibly adaptable, but not always heard or seen. They are today. At Zweig Group, we embrace the idea of Rising Stars. In our Dallas office, I am the oldest staff member by over a decade, and I am not even 40 yet. I am in awe of our office’s work ethic, pace, efficiency of collaboration, dedication, and intelligence. If they were eligible for this award, I would have entered each of their names. The bigger picture I want to make sure we don’t miss today, however, is that each of these 2021 Rising Stars winners that you will read about in the following pages has someone in “the room” advocating for them. As much as we must credit these Rising Stars for their own hard work and subsequent accomplishment, the cold hard truth is unless their firm, a manager, or a mentor, cares to encourage and recognize it, hard work and bril - liance often get buried. I want to applaud all the firms and nominators for taking the time and effort to give credit where it’s due. Giving credit and recognition might actually be the easy part, having created opportunities and carved out space for these Rising Stars to shine is the actual admirable part. Winning this award says a lot about the Rising Stars themselves, but we must not neglect what that also says about these firms. Be it 75 percent or 40 percent, this generation is a (work) force to be reckoned with, and so much more capable than we can probably even imagine. I look forward to growing older and wiser with my fellow emerging pro- fessionals; and making every room and every table we occupy the room to be in and the table to be at. I predict we will see some of our winners in these rooms and tables.

AEC Industry

Once again, it is one of my favorite times of year. We are seeing some trends from the Best Firms To Work For Survey . This gives us a good pulse of how employees are feeling within the industry. We are getting to see some impressive growth from our Hot Firm Award Winners. The marketing campaigns that won our Marketing Excellence Awards were first class and continue to impress our panel of judges. Our Rising Stars in the AEC Industry continues to grow and it is getting more and more difficult to select from the outstanding nominations. All of our award winners deserve to be and will be celebrated. We are very excited to bring back the in-person Elevate AEC conference again this year where we will get to host the huge Awards Ceremony and Black Tie Gala that has become so iconic. Let’s take a quick look at some of what we will be celebrating this year. Numbers overall are up in 2021 when compared to 2020. Not only are they up across the board, but they are up significantly as well. 2021 saw the largest year-over-year increase in our data set dating back to 2018. This is a very good sign. Numbers in 2020 decreased across the board on overage as you would expect to happen during the COVID-19 pandemic. Not only did we see scores rebound from the 2020 dip, they are above where we saw them in 2019. This to me shows that firms are emerging from the strange days of working through the pandemic stronger and in better position than they were before the pandemic. By no means do we want working through a pandemic to be the new normal, but hopefully firms have been able to carry some of the positive adjustments they had to make in 2020 to keep improving and I believe this is evidence of firms doing just that.

From the end of Fiscal year 2017 to the end of FY 2020, the average Hot Firm grew by $29.7 million. They also grew by an average of 85 percent over that same time period. Both of these are incredible growth numbers especially given the challenges that 2020 produced. This is great news. It shows that there is real growth going on in the industry, helping to create and retain good, high paying jobs. This is something we can all celebrate right now. We also saw a very strong group of Rising Stars nominees but especially winners. We will share a little bit more about each one below, but this group really stood out. They all have very unique skill sets and backgrounds. They are technical and non-technical professionals, from all over the United States and outside of it. It is getting really tough to select our Rising Stars in the AEC Industry , but this group deserves to be celebrated for all they have already accomplished.

Vertical Forests as Residential Housing By Luke Carothers

Over the course of the last year or so, much of the world’s population had to grapple with life confined to their home for an indefinite period of time. Many people, as a result of a more home-centered life cycle, have made the decision to move closer to nature. In order to accommo- date this sentiment with those individuals who don’t wish to leave the city, architectural firms such as Dewan are attempting to incorporate nature into award-winning designs. One stunning example of this blending of nature and architecture is Dewan’s Solforest Ecopark, which is currently being constructed in Vietnam. Located in Hanoi, this massive 1,194-unit development is slated to be completed in 2022. The project is inspired by the Ecopark Master Plan model of green living lifestyle, as well as the community culture of Vietnamese cities. During the design phase of the project, the team at Dewan had to convince the developer that a high-rise, high-density project would be successful. While the developer previously had success designing and delivering mid-to-low rise units and amenities, the team at De- wan convinced them that designing the building as a hanging vertical garden with strategically placed balconies and rooftop gardens would maintain the natural countryside aesthetic of the area. What truly makes this project special, however, is the more than mil- lion trees that are incorporated in the design. In addition, the building's towers will also feature rooftop gardens. These green design elements will not just provide a green view for residents of the building, but will immerse them in it. These green design elements also serve a second- ary function. These rooftop gardens and trees function as an extra skin for the building. During the hotter months, the trees and gardens serve to shade the building from the sun, and, in the winter months, they serve to insulate the building, keeping it warm. In addition to designing natural elements for the benefit of the build - ing’s residents, the team at Dewan incorporated a number of amenities that are enhanced by the natural elements. For example, the project features a 200-square-meter multipurpose children’s area, as well as distinct swimming pools for adults and children, barbecue and private gardens, and retail and dining opportunities. With as many trees and gardens as are incorporated into this design, the question of water consumption comes to the forefront. In order to minimize water consumption for the project, the team has designed a cutting-edge watering system. Taking into account both the type of plant being watered and the orientation of the given balcony, the team at Dewan strategically positioned the air conditioning units of each

apartment to drip condensed water into the planters. In addition, the design features grey water recycling that is treated on technical floors and reused for watering in the summer dry months. Most importantly, however, the team at Dewan specifically chose plants that would thrive under these circumstances. The Solforest Ecopark represents a firm-wide intent at Dewan to pro - tect buildings from the natural elements by designing their projects to adapt to their unique surroundings. In turn, this will allow buildings to protect themselves. While this concept came to fruition in the form of greenery based on the climate of Ecopark, the team is also extending this idea to areas such as the Middle East where they are experimenting with building underground, using the soil as insulation and controlling the entrance of direct sunlight.

Contractor Drives Micropile Production, Safety with KLEMM Equipment By Brian M. Fraley

Technical Foundations has been providing specialty foundation con- tracting services along the Eastern Seaboard for 27 years, with a heavy focus on Virginia and the Carolinas. The contractor’s reputation for taking on unique projects is evident in its selection of equipment, the most recent of which was the rental of a KLEMM drilling rig and rod handling attachment from Equipment Corporation of America (ECA). “Technical Foundations specializes in unique projects,” says Project Engineer Butch Stoneman. “We like to provide cost-efficient, innova - tive solutions, and sustainable ground improvements for challenging sites where conventional approaches won't quite work.” The contractor has done business with the ECA Washington branch for more than 10 years. Although the original connection was with Branch Manager Mike Brown – known by Stoneman and many other contractors for his intricate knowledge of the KLEMM line – it was Account Manager Greg Barta that arranged the rental of the drilling rig and rod handling attachment. Technical Foundations is no stranger to KLEMM drilling rigs, but ECA’s KLEMM specialist Burt Kerns was sent to conduct on-site operator training for the team at the beginning of the project since this was the contractor’s first time using the HBR 120 Rod Handling Attachment. Micropiles Chosen to Avoid Disruption Technical Foundations put the KLEMM drilling rig and handling system to work in January 2021 on a project near Roanoke, Vir - ginia. The contractor was hired to install 230 micropiles to support a sizeable commercial building addition and multi-story precast parking garage. The micropiles would be spread across the roughly two-acre site to support the proposed structures in unsuitable soils. The existing site was essentially a valley that had been backfilled with a variety of ma - terials to level it. Technical Foundations started off by test drilling to locate the bedrock. During that process, it discovered that unsuitable fill would make it im - possible to build the structures on conventional spread footers without settlement issues. Various deep foundation systems were considered. The existing business would remain fully operational, so avoiding disruption was

critical. Driven piles were ruled out primarily due to the vibration that would occur with pile driving and heavy equipment. After several load tests, it was determined that six-inch-diameter piles would achieve the right capacity. They were to be clustered in a pile cap configuration around the building columns and under some of the grade beams. Micropile Drilling with the KLEMM The KLEMM KR 806-3G was the primary workhorse for micropile drilling. Technical Foundations had several other rigs on standby. “It was more efficient to have one drill concentrating on drilling and the other focused on grouting the holes afterwards,” says Stoneman. “It was also a really tight schedule, so we had an extra machine out there to make sure our flow of work wasn't interrupted.” The KR 806-3G was drilling piles from 20 feet to 65 feet deep and seating them five feet into bedrock. The top layer of fill material was generally soft and moist, containing a mixture of concrete debris, tree roots, and various types of soil that had been in place for up to 40 years. The native soil below was a weathered rock, which was underlain by bedrock. “We chose the KLEMM because it was the most reliable machine we had available, and with the different features it has, it was going to be a little bit more versatile in difficult drilling conditions,” says Stoneman. Stoneman is referring to the rig’s electronic shifting capabilities, which allow for the changing of torque and speed. The KR 806-3G’s double- head drilling capability was also beneficial since it has separate drives for the outer casing and inner rod. This was especially helpful when drilling through different types of materials and formations. Technical Foundations drilled holes with a KLEMM KR 806-3G and fed rod and casing sections to the rig with an excavator-mounted HBR 120 Rod Handling Attachment on a micropile project near Roanoke, Virginia.

ing rig operator can detach from both joints, then raise the head up, so it's a faster transition to add the next piece of drill steel.” The HBR 120 can fit on any brand of excavator, but Technical Founda - tions kept it mounted on a Komatsu. Mounting the attachment was simple. The contractor built an adapter that allowed the rod handling attachment to be easily mounted to the arm with pins and bolts. A pig- gyback system facilitated the connection of hydraulic hoses and elec- tronics to the fuse block of the excavator. This allowed the operator to easily control the functions of the rod handling attachment, including rotating, tilting, clamping casing, and inner rods. The HBR 120 can rotate on a 360-degree axis, but Technical Founda - tions did not require that level of movement on this project. The bigger focus was getting the rod handling attachment and the drilling rig mast on the right plane to keep the casing properly aligned so the sections would thread properly. This process required careful communication between a spotter and the drilling rig and excavator operators. The KLEMM drilling rig was operated by remote control so he had the flexibility to move into a position with better visibility. The spotter used hand signaling to help both operators to properly line up the joints. Taking Safety to a New Level The KLEMM rod handling attachment also improved safety for the Technical Foundations ground crew. The 10-foot-long inner rod and casing sections were about 300 pounds, which have the potential to cause serious injuries. “By using the rod handler, you reduce the chance of a pipe section Careful hand signaling was required between a spotter and the equipment operators to get the rod handling attachment and drilling rig mast on the right plane to keep the casing sections properly aligned.

KLEMM Rod Handling Attachment Drives Productivity KLEMM Drilling Rigs can be equipped with a MAG 7.0 Revolver, which is ideal for deep foundation methods like tiebacks or soil nails where the casing is being reused. The KR 806-3G Technical Foun - dations rented on the Roanoke project did not have a revolver since micropile casings are a one-time use. The HBR 120 Rod Handling Attachment proved to be a better fit. The drilling crew would drill a hole with the casing and the inner rod. The KR 806-3G operator would leave the casing in place and pull the inner rods. The HBR 120 was then used to grab the inner rod and feed it back into the next piece of casing. “When the crew was ready to start drilling the next hole, they were all ready to go,” says Stoneman. “Having the casing and rods pre-loaded allowed them to drill at a faster production rate.” The smoothness of the micropile drilling operation nearly doubled productivity compared to the contractor’s traditional method. Techni- cal Foundations would traditionally use the winch to hoist the casing and inner rod and make the connection by hand. The contractor would typically achieve 6 to 8 micropiles daily with that method compared to the 14 it completed using the KLEMM rod handling attachment. “The rod handler holds the inner rod and casing still so that we can make the connection to the drill head,” explains Stoneman. “The drill- ECA’s Account Manager Greg Barta arranged the rental of the KLEMM drilling rig and rod handling attachment and KLEMM specialist Burt Kerns conducted on-site operator training for the team at the beginning of the project since this was the contractor’s first time using the HBR 120.

Stoneman says, “Our crew worked through some extreme conditions and the equipment improved productivity, so we finished the job sev - eral days ahead of schedule even after starting about a week behind.” Technical Foundations rented the KLEMM drilling rig and rod han - dling attachment from ECA for the Roanoke project. After it was com- plete, the safety and productivity gains combined with the potential for future projects made the decision to purchase the HBR 120 an easy one for the contractor. Technical Foundations didn’t have enough relevant work to keep the KR 806-3G consistently busy at that point. “We were exceptionally pleased with the productivity and the safety it (HBR 120) added to the project,” says Stoneman. “We see multiple places where it will benefit us in the future.”

coming loose and falling and hurting somebody, but you also are able to get people's hands away from joints,” says Stoneman. “When you can fully eliminate serious injury or any potential human contact, it's a positive thing.” The ability to control the KLEMM drilling rig via remote control added to the safety of the micropile drilling operation. Groundwater kept dust control at a minimum on the Roanoke project, but the ability for the operator to move to an area with improved visibility was helpful. “With the remote control, the operator can position himself where he's out of the dust that can occur during drilling and in a place where he can best see what's going on,” Stoneman says. “The farther away you can get from the machine, the safer the operator is.” Beating the Deadline Despite Additional Micropiles The owner at the Roanoke project had a drop-dead opening date for this building, so they couldn't extend the schedule, according to Stone- man. Further complicating matters, the owner called for 40 additional piles between the bid submission and project start date. Technical Foundations arrived on site at the Roanoke project in January of 2021 and finished in late February of 2021. Technical Foundations completed 14 micropiles per day because of the KLEMM rod handling attachment, compared to the 6 to 8 it would normally achieve using traditional methods.

The HBR 120 can rotate on a 360-degree axis, but Technical Foundations did not require that level of movement on this project.

Vancouver’s new Fire Hall 17 reflects the city’s design challenge to build a structure that meets the design certification requirements of the Canada Green Building Council’s Zero Carbon Building Program, one of 16 such pilot projects in Canada. The partners are also pursuing LEED Gold certification and, if approved, the building will be the first fire hall in North America to attain Passive House certification. These ambitious targets were set to align with City’s sustainability policies. According to HCMAArchitecture and Design, the building will reduce operational carbon emissions by 77 percent, compared with the fire hall it is replacing. The 19,375 sq ft (1800 m2) facility comprises four drive-through appa- ratus bays, accommodations for two firefighting crews and offices in the main building, and a six-story hose storage/training tower. Like all fire halls in Canada, the facility will serve as a post-disaster emergency hub, which requires a resilient building that can withstand seismic events. To meet the seismic requirements of Canada’s National Building code, the building has a stout reinforced concrete structure with a structural steel frame for portions of the third level. The main building is clad in brick and metal panels that cant outward at the base giving the form a strong and sturdy presence. Mitigating exterior and interior thermal bridging Central to meeting zero carbon goals is the building’s high-performance envelope, which wraps reinforced concrete walls with an 8 in. (20 cm) thick layer of mineral wool board having an R-value of 33, and an air barrier that allows a scant 0.6 of air change per hour at 50 Pascals of pressure. However, structural concrete and steel elements that penetrate the en- velope between the main building and tower, maintained at dissimilar temperatures, would allow the unabated passage of heat energy, absent a thermal bridging solution. “The fire hall has two thermal zones: the administrative offices and living spaces set 68˚F (20˚C), and the ground-level apparatus bay and training tower set to 50˚F (10˚C),” says Elise Woestyn, Passive House consultant with HCMA Architecture and Design. The struc- tures share a concrete frame at ground level, and are connected by combinations of steel frame and concrete bridges on levels two and CERTIFICATION, INCORPORATES STRUCTURAL THERMAL BREAKS City of Vancouver sets aggressive environmental goals for the new facility

three, and a steel frame at level four. Due to the temperature differ- ences, the designers needed to thermally isolate the two zones, while maintaining structural continuity. “Our need to address thermal bridging led us to structural thermal breaks,” says Federica Piccone, architect with HCMA Architecture and Design. At the connection points, the design team specified Isokorb® concrete- to-concrete and concrete-to-steel structural thermal breaks fromSchöck North America. Each concrete-to-concrete module consists of a rigid foam block penetrated by stainless steel rebar that is tied into rebar on both sides of the slab or wall before concrete is poured conventionally. Each concrete-to-steel structural thermal break includes stainless steel rebar projecting from one side of the module that ties into rebar of the interior slab, and stainless steel threaded rod projecting from the opposite side of the module that bolts to exterior steel beam flanges. Three concrete balconies also project from the tower’s facade. Con- crete-to-concrete thermal breaks were installed between each balcony and interior slab to mitigate thermal bridging, while withstanding the rotational and shear forces created by these cantilevers.
