looking back, moving forward
As early railroad technology developed, engineers grappled with the challenge of moving cars up and down inclines. Early railroads were often constructed in the same way a canal would be, with large stretches of flat railway connected by specialized inclined systems to move cars up or down the elevation to another section of track. As railroad technology developed, and standard cars were able to navigate greater inclines as a result of more powerful engines, many of these specialized inclined systems fell out of favor–being relegated for specialized tasks in mines and high elevation construction. Notable among these specialized inclined railroad systems is the funicular, which bucked the trend and became a wildly popular option for American cities looking to provide their citizens with public transportation. Compared to other inclined railway systems, the funicular is remarkably simple from a mechanical perspective. Operating on a counterweight pulley system, funiculars rely on the kinetic energy of a descending car to raise an ascending car–requiring very little power to run the system. The two cars operate on either a single- or double-track system, moving passengers from between stations at the top and bottom of the incline. Because of their simple design, funiculars were a cheap and efficient option for moving people up and down inclines in urban spaces. During the latter half of the 19th century, funicular construction boomed across the United States. Cities like Pittsburgh, Cincinnati, Los Angeles, and many places in between recognized the value of the system, and funicular railroads began to pop up to connect neighborhoods in places with steep elevation. During this time, the city of Pittsburgh constructed 17-passenger carrying funicular inclines, the oldest of which being the Monongahela Incline built in 1870. Like many cities during the Industrial Revolution, Pittsburgh was quickly becoming home to a growing population of people immigrating to the United States. As Pittsburgh’s population expanded, their newest residents made their homes on the steep inclines of Mt. Washington. Also known as Coal Hill, these new neighborhoods were built on the only land available to Pittsburgh’s residents, as most of the flat land around the city’s rivers was occupied by industry. This new neighborhood gave citizens a respite from the soot and smoke that clouded lower areas in the city and was geographically close to the center of industry. However, the difference in elevation between these populations and industrial areas represented a problem when it came to staffing the factories, workshops, and foundries that crowded Pittsburgh’s riverfront. A Simple System: Funiculars in American History Luke Carothers
S. Clery: Original digital image, Monongahela Incline, Pittsburgh, Nov 2006
The solution was a funicular designed to carry passengers between the top and bottom of Mount Washington’s steep incline, and the Monongahela Incline was opened to public use in 1870. The 635-foot long system was designed by Prussian-born engineer John Endres who watched as more than 5,000 people used the incline in its first two days of operation. The Monongahela Incline still exists to this day, although it is currently closed to the public for renovations. Following its construction and popularity, Pittsburgh would construct another 16 funiculars over the next several decades. This trend would expand rapidly, and hundreds of funiculars were constructed during the latter half of the 19th century. However, despite their simplicity and efficiency, funiculars fell out of favor just as quickly as they rose in prominence. By the end of the 20th century, only a handful of funiculars remain in the United States, and fewer still remain in operation at anywhere near the capacity as a century prior. Of the 17 funicular railroads built in Pittsburgh during this time, only two remain–the Monongahela and Duquesne Inclines. Despite falling from popularity, this simple system had a profound effect on the development of American cities, allowing for dense urban development in cities with steep inclines.

Industry Insights
Some remarkable shifts in recruiting and retention have transpired over the last year, all traceable to the acute rise in talent demand on the heels of a continued breakout economy. In unprecedented fashion, the AEC industry witnessed rapidly evolving job market conditions, industry trends, and technological advancements. These sharp shifts have brought about a sudden and significant talent shortage felt industry- wide, necessitating nimble responses from recruiting and HR leaders to attract and retain the talent their firms need to thrive. And there’s no immediate reprieve on the horizon. The fierce demand for talent continues to fuel augmented (sometimes inordinate) compensation expectations, multiple job offers from competitors, and retention tactics on an ever evolving scale. As we examine these trends, we can’t help but ask some very provocative questions about what lies ahead for recruiting and retention: What is the technology that we need to own and master today to win the war for talent? How does our selection process need to evolve to be more efficient, faster, and opportunistic? What key indicators should we be measuring and why? Do the recruiting and retention leaders in our firms have a seat at the strategic planning table? What do we need to do proactively to cultivate diversity at every level of the organization, and to ensure that we are viewed as an employer of choice? What is our position on remote hiring and onboarding, and does it need to evolve? What are we doing right now to benchmark our compensation practices against quickly evolving industry standards? Do we have structured career-pathing in place, and are we openly sharing it and mentoring our people accordingly? It all seems a bit overwhelming. That said, no matter what circumstances we face here are five foundational areas your firm can camp on every day to help recruit and retain your best people: The past few years have had a lot to teach us about winning the war for talent. Have you been listening? By Jeremy Clarke, Director of Executive Search and Recruiting, Zweig Group

Background Orlando International Airport (MCO) is Florida’s busiest airport, serving 50 million passengers annually before projections for rapid growth driven by the city’s business growth and tourism. The new 1.8 million square foot Terminal C facility addresses the challenges of rapid growth by increasing capacity while continuing to provide an exemplary passenger experience. It features elements that maximize the safety, security, and efficiency of the travel process including 100 percent automated screening lanes, 100 percent facial recognition “e-gates” for international departure, an innovative landside terminal design, and 100 percent trackable RFID Independent Carrier System. Terminal C’s design successfully navigated an aggressive four-year construction schedule without disrupting airport operations. The project leveraged four alternative delivery methods including: landside and airside construction management at-risk, a design-build-operate- maintain baggage team, design-bid-build award contracts and multiple design-build concession/tenant packages. An ode to the region, the terminal is an architectural depiction of everything that attracts tourists to Central Florida. The terminal’s design captures the elements of water, foliage and sky with expansive glass skylights, terrazzo art interpretations of natural springs and incredibly life-like artificial palm and bald cypress trees.
Impact Terminal C at the Orlando International Airport is designed to be part of one the first LEEDv4 airport campuses, reflecting the airport’s commitment to sustainability and environmental responsibility. The building’s strategic design includes a 35 percent targeted reduction in potable water use through efficient fixtures and equipment, a 25 percent targeted reduction in energy costs with a focus on thermal performance and optimal heating, and a 360-panel floating solar array to name a few. Terminal C also has a tremendous impact on the local community by being one of the first airports to fully integrate multimodal ground- air-rail transportation, including rail to South Florida that is now in operation. Technical Aspects • Aggressive four-year construction schedule to minimize disruption to current airport operations • Virtual design and construction modeling identified potential risks before construction and avoided conflicts by allowing contractors to sequence mechanical, electrical and plumbing work in tight quarters • Moving of 4,000,000 cubic yard of dirt and pouring of approximately 4.6 million square feet of concrete and asphalt pavement

Background The 74-foot single-span steel stringer bridge on Day County Highway 1 over Blue Dog Lake had faced flooding for several years, as the road is only two feet higher in elevation than the outlet of the lake. IMEG initially conducted a hydraulic analysis, and a single-span concrete girder bridge was selected as the replacement structure, but, by the time the design was initiated, the site sustained back-to-back 100-year storm events that caused the lake to rise considerably–making the existing structure selection unusable. IMEG reanalyzed the hydraulics and a four-cell cast-in-place concrete box culvert was selected as the structure. Construction was completed over the winter season, from November to April, which created challenges with protecting the concrete during the curing process in extreme cold temperatures.
Impact The road serves as the primary paved connection between City of Waubay and the Enemy Swim Day School District as well as several residences and small businesses along Blue Dog Lake and Enemy Swim Lake. Because the bridge was prone to flooding prior to the construction of the box culvert, residents were faced with long detours around the lake to reach their destinations. The new box culvert significantly improves travel times and accessibility for the community, and is designed so that the road grade can be raised an additional four feet to help alleviate flooding issues going forward. Technical Aspects • Revision of hydraulic and hydraulic analysis to provide design for new equalizer box culvert to conduct water from one side of the road to the other and protect it from flooding • Utilization of thermal concrete blankets to keep concrete above 50 degrees for three days and above 40 degree for two additional days

slope protection system. Initially, the plan was to place loose rip-rap rock on the slope to prevent material sloughing. After consideration from the project team, it was decided to utilize a fabric formed concrete mattress. This mattress, in place of the rip-rap rock, allows for more connected slope protection and prevents loose rocks from sliding into the dredge template. By doing this, dredging maintenance will be more efficient due to reduced debris in the template in the long term. Technical Aspects • Combiwall bulkhead consisting of 171 plumb piles, 105 batter piles, and 148 pairs of sheet piles • Vertical travel transfixed lead system to drive pipe piles for bulkhead, increasing producing and reducing material cost
Background Port Freeport, sixty miles from downtown Houston, is one of the fastest-growing ports in Texas and is undertaking expansion to handle an increased flow of goods. In 2020, Port Freeport hired McCarthy Building Companies as the Prime General Contractor to execute the Velasco Terminal Berth 8 expansion–a $129 million project which later grew to $140 million with the addition of a Roll-on Roll-off dock adjacent to Berth 8. McCarthy first had to construct this project's bulkhead portion, which was a critical component of the Freeport protection levee system and vital for flood control purposes. This infrastructure expansion doubles the capacity of Port Freeport’s import and export operations and allows simultaneous ship-to-shore operations of multiple post-Panamax ships. With its new capacities, Port Freeport will continue to grow as one of the Texas Gulf Coast and National export and import industry-leading ports, and the Velasco Terminal Berth 8 project served as the catalyst to do just that. Impact Because the Velasco Terminal Berth 8 project site was located on the water, there were many environmental and spill prevention plans in place to prevent leaks from equipment, as well as debris from getting into the water. One interesting aspect of the project modified to allow long-term benefits to the area was the modification of the under-dock

and serving as a backup during emergencies or closures due to construction. The project’s location crosses a superfund site, which made special drainage measures–such as realigning the groundwater remediation system while ensuring the treatment facility experienced no downtime. Furthermore, the project included the removal of old remediation water lines in an environmentally-safe way, demonstrating that the care invested in design and construction will further support site rehabilitation to open opportunities for economic development along the corridor. Technical Aspects • Revision of roadway section to include protected bicycle/pedestrian lanes based on community input • Innovative bridge construction technique using a steel triangle and Kevlar straps, allowing one crane to pass a girder to a second crane while suspended overhead • Reduction of construction costs through innovative design solutions
Background The Sunport Boulevard Extension created a new roadway corridor between I-25 and Broadway near the Albuquerque International Sunport with the road of improving the roadway system and multimodal connectivity from the I-25/Sunport Interchange to Broadway Boulevard and Second Street. Beyond boosting transportation connectivity, the project aims to enhance access to existing and prospective economic hubs, balance traffic, alleviate congestion by adding another link to the arterial system, expand multimodal options, and boost emergency accessibility. The design was split into two portions: the I-25/Sunport Interchange Reconfiguration and the Roadway Extension from I-25 to Broadway. The four-lane divided highway also features a protected bike lane, shielded from traffic with a concrete wall barrier. The design also incorporated bridge crossings: two twin single-span bridges cross Edmunds Road and a three-span bridge over the South Diversion Channel. Construction on the extension portion of Sunport went to bid in April 2021, and the new roadway was completed in June 2023. Impact The Sunport Boulevard project is a much-needed transportation infrastructure solution that bridges a significant gap in the local transportation network, providing improved multimodal transportation options for pedestrians and cyclists while also easing traffic congestion

Background The Ballston Pond was originally designed and constructed as a stormwater facility to collect and slow runoff from Interstate 66 when the highway was built, but, over the years, the pond has filled up with sediments deposited by stormwater runoff. Retrofitting the Ballston Wetland Park was a high-priority project in Arlington County’s Stormwater Management Program, and they were able to seek community input through a stakeholder advisory committee as well as with several community meetings to provide input to the design process. Additionally, retrofitting the pond to provide higher quality water treatment helps the county comply with the municipal separate storm sewer system permit and contributes to restoring the Chesapeake Bay. The County sought community input through a stakeholder advisory committee and with several community meetings to provide input to the design process, guiding the eventual selection of the preferred wetland design. Impact Cleared of sediment and now capable of taking excess rainwater from 450 surrounding acres, the retrofitted wetland system improves stormwater flow and filtering–plus capturing trash–while also serving as a wildlife refuge and pastoral commons within the Ballston “urban village” setting. The park expands Arlington County’s ability to meet Chesapeake Bay Watershed regulations while cultivating native plants and providing new boardwalk areas and fresh interpretive designs. Community input from the engagement process helped to guide the selection of new features at the wetland park such as trash collection devices, an expanded viewing platform, interpretive signs, and wildlife habitat.
Technical Aspects • Stormwater pollutant removal in a constructed stormwater wetland • Sediment collection in the pond forebay–allowing for easier maintenance and removal • Trash and debris collection in StormRax trash rack and WATERGOAT floating trash barrier trash collection devices

mere utility to become a hub for community interaction and recreation, with ADA-accessible trails, sports fields, and spaces that promote communal activities, while also serving as a verdant connector for essential community spots like schools and religious institutions. Technical Aspects • Excavation of 2,440,000 cubic yards of material across five distinct phases • Strategic blend of engineering and ecology to pursue the re- establishment of a native habitat through extensive research into native grasses and seedbed preparation • Installation of culverts and re-evaluation of soil management strategies
Background Located in the heart of Clear Lake residential community near Houston, the visionary project of Exploration Green epitomizes a successful transition from a once-popular golf course to a sprawling 880.6-acre-foot, sustainable detention facilities, fulfilling roles of flood control, enhancing water quality, and providing a verdant natural habitat for wildlife and recreation space for residents. The transition from a golf course to a pragmatic, environment-centric space stemmed from a compelling need for improved drainage control and flood management, was driven by the residents and expertly addressed by the Clear Lake City Water Authority (CLCWA). The initiative's backbone, Exploration Green, was divided into five meticulous phases and conceived with community input, unifying expert planning and genuine residential needs. Planned by SWA Group architects and designed and managed by the engineering firm Lockwood, Andrews & Newnam Inc., the project metamorphosed into a massive nature park, encompassing five substantial in-line wet bottom detention ponds, each capable of holding approximately 100 million gallons of stormwater, crucially mitigating flood risks. Impact Community involvement was paramount from inception to fruition, with a series of town hall meetings anchoring the project's development to the desires and needs of the residents. The resultant multifaceted benefits impact not only the local community but set a precedent for nationwide flood management and environmental conservation. Environmentally, Exploration Green, of the 153 acres of natural habitat, 14 acres is dedicated wetlands. Socially, the project transcends

Background To create a sustainable future and achieve the goals outlined in its Master Plan and Most Livable City Plan, the City of Gulf Breeze needed creative, cost-effective solutions to implement multi-modal improvements within the existing right-of-way of the City’s primary collector ‘loop’ roadway. The project included surveying, engineering, and landscape architecture services to design a new 10-foot-wide multi-use pathway along the Fairpoint Drive/Shoreline Drive loop, approximately four miles in length, that supports multi-modal transportation for bikes, carts, scooters, and other wheeled modes of transport in this active area of Gulf Breeze. To better understand the impact to all residents of Gulf Breeze, multiple community outreach efforts were conducted to educate citizens about the project and gather public input early in the project’s development, such that the input could truly influence the final design. This project also included intersection safety improvements at side streets and critical mid-block crossing locations, along with rehabilitation and upgrade of an existing 5-foot- wide sidewalk to provide an Americans with Disabilities Act (ADA)- compliant path for pedestrian foot traffic. A separate pile-supported wood boardwalk was designed to traverse across low lying wetlands in nearby Shoreline Park, providing interconnectivity between residential neighborhoods and the public park as well as a new public beach access along Santa Rosa Sound.
Impact The project outcomes that benefit the community includes enhanced capacity for collection and infiltration of stormwater runoff within the City’s right-of-way, the inclusion of twenty xeriscape gardens along the Multi-Use Pathway to highlight and enhance the entrances to various neighborhoods along the route, and highlighting the diversity of abundant flora and fauna within the Shoreline Park South ecosystem. It provides environmental education opportunities for local elementary, middle, and high school students while also attracting ecotourism and providing increased interconnectivity between local neighborhoods and businesses. Technical Aspects • MoDaC Mobile Data Collection was utilized, incorporating LiDAR and 360-degree videos and photographs in combination with conventional survey techniques to not only provide the necessary data points, but to generate maps, exhibits, and interactive
workstations for Public Input Meetings • Side Street Intersection Safety Upgrades • Sidewalk Rehabilitation

Background Mirasol Village is a $300 million mixed-income redevelopment in Sacramento’s River District that replaces the 1940s era Twin Rivers housing development and infrastructure. The area will be fully connected to new transit, employment centers, services, retail, and cultural amenities–creating a gateway to downtown Sacramento. The redevelopment included new backbone infrastructure, a community park and garden, and mixed-income housing. The onsite improvement included raising site grades by several feet using imported soil, construction of multiple two- to four- story multifamily buildings, and a five-story mixed-use podium structure. Site improvements included underground utilities, below-grade Chambermaxx® systems, a swimming pool, jointed plain concrete pavement, and pervious concrete. This project used a unique approach to store and infiltrate 100 percent of the design event runoff while optimizing the number of developable units. By incorporating below-grade Chambermaxx systems, stormwater planters, and pervious concrete, the design runoff was contained while still meeting water quality requirements.
Impact The backbone of this project was infrastructure that included new roadways, underground utilities, large stormwater planters, detention basins, and below-ground stormwater storage. The project also included other public improvements such as the construction of the Mirasol Community Park and Garden. The project used a unique approach to store and infiltrate 100 percent of the design event runoff while optimizing the number of developable units. Technical Aspects • Shallow infiltration testing as a part of 2016 geotechnical exploration, followed by supplemental infiltration testing at greater depths within the par basin • Corrective grading recommendations to remove and replace shallow silt with more pervious imported sand • Development for design criteria of 3 inches differential settlement over 50-feet of seismic conditions

Background RISE, or Residences for Innovative Student Entrepreneurs, is a brand- new integrated, live, learn, work, innovation center at the University of Hawaii (UH) at Manoa campus. RISE is a unique facility with dormitory-style housing for 374 students, from freshmen to graduate students. The RISE development offers housing, workspace, and resources for students interested in entrepreneurship and innovation. The goal is to create a collaborative environment that would encourage students to develop their ideas and work on entrepreneurial projects. The building includes co-working spaces, meeting rooms, and other amenities to support these efforts. RISE is managed by B.HOM Student Living as UH’s first externally managed student housing complex. It was developed as a public-private partnership between the University of Hawaii, the University of Hawaii Foundation and developer Hunt Companies.
Impact RISE enhances the educational experience of UH students by providing a space for entrepreneurial activities, innovation, and collaboration. This center provides local students with greater opportunities to sharpen their innovation skills which will have a lasting positive impact on the rest of the university and local business industry. This development also repurposed and gave new life to a historic, 100-year-old building that was in a state of disarray. Instead of demolishing it and building new, repurposing the original structure provided environmental benefits to the local community including less pollution and disturbance of the site. Technical Aspects • Development of two separate new structures and renovation of the historic, 100-year-old Charles Atherton House • Intricate system of seismic expansion joints were designed to connect the three structures • New structures designed with post-tensioned concrete podiums and cold-formed steel framing (CFS) above

for a rapidly expanding population of North Texans. Bois d’Arc Lake will provide water services for nearly 80 communities just outside of the Dallas-Fort Worth Metroplex–an area that is expected to double in population by 2050 according to the NTMWD. The Leonard Water Treatment Plant (WTP) will treat water from Bois d’Arc Lake to meet federal and state standards, which is necessary when delivering water to the northern portion of the NTMWD’s service area. Technical Aspects • Fully equipped onsite concrete and soil laboratories dedicated to the project and staffed by certified engineering technicians • Development of GIS-based program to track testing results in real time, particularly for the reservoir dam • AWS-certified welding inspectors responsible for inspecting weld quality (both pipe and structural welds), structural inspections, and workmanship
Background Bois d’Arc is a $1.6 billion water supply program that is the first major water reservoir built in Texas in nearly 30 years and is designed to meet the water needs of the area’s growing population of more than two million people in 80 communities. Alpha Testing, a UES company, was chosen by the North Texas Municipal Water District (NTMWD) to provide quality control/construction materials testing services to multiple project teams. Bois d’Arc Lake will span 16,641 acres. The dam is two miles long and 90-feet tall, with a 110-foot-tall intake tower. It collects water and filters through the Raw Water Pipeline to the Leonard WTP. The 90-inch diameter Raw Water Pipeline travels 35 miles from the dam, delivering untreated water to the treatment plant. The Leonard WTP includes six pumps to filter and treat 90 MGD of water to then go through the Treated Water Pipeline. Alpha Testing utilized two on-site laboratories and up to 15 full-time field and laboratory personnel to serve the Bois d’Arc lake project that will span 16,641 acres. Impact Because the project site is located on Bois d'Arc Lake, it will be a tourist and residential destination for numerous outdoor recreational outdoor activities including fishing, boating, and time spent by the water while also serving as a critical water source as demand grows

Background Remnants from Hurricane Harvey in 2017 hovered over Central Texas for several days, creating flooding throughout the region that damaged structures such as the historic Buescher State Park Dam. The dam’s structural integrity was threatened as several feet of material eroded away during the rain event, and the Texas Parks and Wildlife Department (TPWD) needed to find an immediate solution that would preserve the historic structure and protect a critical economic resource. Halff was contracted to perform emergency repairs that stabilized the dam and prevented a breach. After the emergency repair and understanding the importance of a more permanent solution, TPWD again contracted Halff to implement detailed construction plans, specifications, and cost estimates for rehabilitating the dam to comply with current regulations, which included improvements to the dam’s embankment and principal spillway. The newly designed Buescher State Park Dam retains historical homages to the original structure, such as the native red sandstone, while offering a structure that meets current standards and can preserve the economic importance of the park for years to come.
Impact By finding a permanent solution for the dam, TPWD has been able to reopen its recreation program, which will ultimately help lift the local economies of Smithville and Bastrop. Halff worked with the U.S. Army Corps of Engineers (USACE) to improve stream functionality with a riffle-pool sequence. Once fully established, this will provide an additional habitat for the native amphibians and birds within the park. Halff also developed an innovative approach to reduce potential impacts to endangered species, particularly the Houston toad, which included measures like taking a traditional silt fence and repurposing it to develop toad exclusion fencing. Design enhancements for the new structure included installing a sharp-crested, straight drop principal spillway, training/retraining walls, grading, native stone rock riprap and stream enhancements. Technical Aspects • Spillway improvement features more than 340-feet of retaining walls, a stifling basin, and a 200-foot sharp crested weir and spillway chute • Dam design and dam breach analysis

the stress of a highly urbanized environment. The Project includes the following improvements: establishment of landscapes around the subsurface storage system, restoration of the baseball field, restoration of the existing irrigation system, replacement and restoration of light poles and electrical conduit, and restoration of streets and sidewalks. The Project enhances the community's quality of life by encouraging recreational activities that help maintain a healthy community. Technical Aspects • Diversion and pre-treatment of runoff from three local storm drains into a subsurface storage system for infiltration • Subsurface storage system footprint of 15.6 addition acre-feet, resulting in a single-storm capture volume of 25-acre feet • Pretreated flows conveyed through a gate valve
Background The City of San Fernando (City) is implementing the San Fernando Regional Park Infiltration Project (Project). The Project was identified in the Upper Los Angeles River (ULAR) Enhanced Watershed Management Program (EWMP) Plan as a priority regional project and will assist the ULAR group in addressing applicable Total Maximum Daily Loads (TMDLs) and water quality priorities. The primary goals of the Project were to improve water quality while providing multiple benefits. The Project will divert and capture wet- and dry- weather runoff from over 940 acres, effectively reducing pollutant loads that would otherwise enter Pacoima Wash and the Los Angeles River. The captured runoff will be pretreated and then discharged into a subsurface storage system that will facilitate infiltration at the San Fernando Regional Park, resulting in groundwater recharge. In addition to recharge and water quality benefits, the Project will have additional benefits including flood control benefits and public outreach benefits (outreach events and permanent signage). Impact The 9.5-acre park includes the San Fernando Regional Pool and Community Center, a children’s play area, and athletic fields. Surrounded by urban development, the park is bound by a Metropolitan Transit Authority (MTA) railway to the west along First Street, industrial parks on the south and east corners, and medium-density housing to the north on Park Avenue. The Project ensures continued use of San Fernando Recreation Park by the DAC seeking respite from
