Gerardo Pittaro is our Director of Tunnels and Underground Construction in the Latin America region, bringing more than 15 years of experience delivering complex underground infrastructure projects from tender stage through construction.

Originally from Argentina, Gerardo began his career in Italy before relocating to Singapore in 2014, where he completed his Ph.D. and spent nearly a decade working on major underground transport projects. Today, he combines his technical expertise and leadership experience in client relationships and project delivery to help our teams support complex underground infrastructure across Latin America.


What drew you into the tunneling industry and what motivates your work today?

I began my career as a civil engineer and developed an interest in underground infrastructure. As I progressed in my studies and early professional work, I became increasingly involved in projects focused on deep excavations and tunneling.

What motivates me is the role underground engineering solutions play in solving many of the infrastructure challenges that growing cities face. Underground construction offers sustainable solutions that help cities function more efficiently and minimize surface disruption.

Tunnels support a wide range of infrastructure applications, from rail and highway systems to electrical cables, telecommunications networks and other critical infrastructure across industries. As my career has progressed, collaborating with leaders across diverse market sectors and learning from key actors in different regions has been inspiring and a strong source of motivation.

What are some of the biggest challenges facing the tunneling industry today?

Tunnels provide strong infrastructure solutions, but they also involve complex risks during design and construction. One of the most important challenges today is learning how to efficiently integrate new technology to mitigate those risks. For example, advanced modeling tools and AI help engineers better predict soil and ground behavior during excavation. Using these tools while maintaining a pragmatic and realistic engineering approach remains a significant challenge.

Another challenge is that the economic context of projects can vary greatly from region to region. In places with long-term infrastructure plans and dedicated funding, tunneling solutions are often the best choice. But in developing countries, tunnels can be harder to implement because they typically require higher upfront investment compared to more affordable infrastructure alternatives. Clearly demonstrating the long-term value of underground solutions is a key priority with project partners. I work closely with clients to navigate these considerations and help them understand how tunneling solutions can yield the most effective and sustainable outcomes.

How does your international experience shape the way you approach projects in Latin America?

Working across regions has shaped how I approach projects by bringing a broader perspective on how underground infrastructure can be planned, delivered and integrated into cities. In Singapore, for example, tunnel development is often planned decades in advance and used for multiple applications such as transportation systems, utilities, water networks and underground storage. My experience allows me to approach projects in Latin America with a more long-term and integrated mindset, helping clients see how underground solutions can support future growth, not just immediate needs.

My international experience enables me to take a collaborative approach with colleagues around the world, which is critical when our teams face complex regional challenges. Having a network of international professionals allows us to leverage proven solutions from similar conditions and demonstrate their value to our clients. Many cities in Latin America could benefit significantly from established underground solutions, and access to global insights from successful projects helps build confidence in these approaches among local stakeholders.

What opportunities excite you the most about the future of underground infrastructure?

I’m encouraged by the growing global popularity of tunneling solutions in recent decades. As a result, clients and stakeholders are increasingly familiar with these solutions and more confident in their implementation.

I’m also excited by advances in modeling tools, data analysis and AI, all of which can help engineers better understand underground conditions and improve design efficiency and sustainability. These technologies reduce risks during construction and facilitate informed decisions throughout the project lifecycle.

This combination of technological progress and global knowledge transfer creates an opportunity to apply best practices from projects around the world to major infrastructure challenges in Latin America. We are seeing this with the Panama Metro Line 3, which includes the first tunnel constructed beneath the Panama Canal. Projects like this demonstrate how international collaboration can help deliver complex underground infrastructure that supports long-term regional development.

Our Buildings + Places Advisory team conducted an analysis of New York City’s “City of Yes” initiative to uncover where zoning changes unlock new opportunities for much-needed housing development.


On December 5, 2024, New York City adopted City of Yes for Housing Opportunity, the most significant update to the city’s zoning code since 1961. The city faces a persistent housing shortage, with experts estimating that 473,000 additional housing units will be needed by 2032 to meet demand. City of Yes aims to address this this issue by increasing allowable housing density, facilitating office-to-residential conversions, and reducing parking requirements. In doing so, the initiative is expected to enable the creation of 80,000 new housing units over the next 15 years.

How City of Yes expands housing development

A key feature of the plan is the Universal Affordability Preference (UAP) program, which allows developers in medium- and high-density areas to build 20% more housing if the additional units are affordable to households earning 60% of the Area Median Income (AMI). This policy was designed to complement the 485-x tax incentive, ensuring that new residential projects remain financially viable.

The Floor Area Ratio (FAR) increases enabled by City of Yes vary by zoning district, street width, and whether the site is inside or outside the Manhattan core. Developments in historic districts still must adhere to the Landmarks Preservation Commission’s regulations to preserve neighborhood character.

Where does this create the biggest opportunity?

To better understand the impact of these zoning changes, our team at 91Ӱ mapped the new maximum allowable floor area under the UAP program. By comparing previous limits with new maximums, our team identified neighborhoods with the greatest newly unlocked development potential. Use the interactive map below to explore the impact of the City of Yes in each neighborhood. To find a specific area, use the search function in the top right corner. The legend is found immediately below the search function.

Percent Increase in Maximum Allowable Square Footage by Neighborhood

Some neighborhoods saw substantial increases in their development potential. Park Slope and Prospect Heights in Brooklyn, along with Bronx Park in the Bronx, have seen the largest increases in maximum allowable square footage under City of Yes.

NeighborhoodPercent Increase in Maximum Allowable SF
Park Slope (Brooklyn)19.8%
Prospect Heights (Brooklyn)17.6%
Bronx Park (Bronx)17.4%
Bedford-Stuyvesant (East) (Brooklyn)15.5%
Bedford-Stuyvesant (West) (Brooklyn)15.0%
Hamilton Heights-Sugar Hill (Manhattan)13.7%
Flatbush (Brooklyn)12.2%
Astoria (Central) (Queens)12.2%
Upper East Side-Carnegie Hill (Manhattan)11.7%
Sunset Park (Central) (Brooklyn)11.7%
Top 10 Neighborhoods by Percent Increase in Maximum Allowable SF

Available development rights by parcel

Our analysis also compared the existing built-out floor area with new maximums to identify unused development rights at the parcel level.

Most parcels receiving a Floor Area Ratio (FAR) boost under City of Yes saw an increase of less than 2.0. While these individual increases may seem modest, they collectively enable an additional 295 million square feet of development citywide.

FAR Availability Near Prospect Park in Brooklyn

Many of the City’s most underbuilt parcels tend to be in commercially zoned districts, which are largely unaffected by the UAP program. For example, Atlantic Avenue-Barclays Center station in Brooklyn has a concentration of underbuilt commercial parcels near the transit hub, presenting an opportunity for additional transit-oriented development.

FAR Availability Near Barclays Center in Brooklyn

Beyond the UAP program, City of Yes also expands eligibility for office-to-residential conversions. Now, buildings constructed as recently as 1990 can be converted to housing in any area where residential uses are permitted. This shift could be particularly impactful in neighborhoods like Midtown Manhattan, where many office spaces remain underutilized.

What’s next?

With City of Yes now in effect, developers, city officials, and community members have new tools to help address New York’s housing shortage. Understanding how these zoning changes impact specific properties and neighborhoods is key to making the most of this opportunity.

At 91Ӱ, employees are encouraged and supported to pursue career paths that best fit their unique capabilities, interests, and aspirations. Our Career Path Spotlight series takes you through the rewarding career journeys of our employees who have stepped out of their comfort zone and taken on new challenges to chart their own successful careers and growth. 

This time, we connected with Karen Campbell, Vice President, Austin Metro+ Executive in the West region to learn how she progressed in her career path.

Hi Karen. What do you do for 91Ӱ?

As Vice President, Austin Metro+ Executive, I wear two hats: Austin Metro+ lead and West Region Specialist Pursuit Team Lead. I’ve been at 91Ӱ for 18 years working in our Denver, CO; Santa Ana, CA; and now Austin, TX office.

Tell us about your career journey and how you got here.

I started as a proposal coordinator in legacy company Woodward-Clyde’s Federal Services proposal center in Denver, Colorado. In this role, I was responsible for supporting senior proposal managers. After nearly two years, I started to lead my own major federal proposals and engaged directly with capture managers, project managers, and client account managers to prepare proposals and presentations. After five years, I applied for an internal open marketing position in Southern California to expand my skills from just federal to include state, municipal and private sector proposals.

After I transferred to our Santa Ana, California office, there was an open position to lead the Southern California proposal center. Even though I had fewer years of experience than suggested, I jumped at the opportunity and approached the office manager to give me a chance. We both took a leap of faith and worked closely together over the next four years to create a winning proposal center.

In 2003, I took another leap of faith and left 91Ӱ to move to Hawaii and start my own soda company with my husband. As a new business owner, I was running every aspect of our company from accounting, marketing and business development to supply, production, customer and investor relations. Ten years and two kids later, we decided to move back to the mainland (Austin, Texas) to be closer to family and run the business remotely.

Using my network in California, I was introduced to the Process Technologies business leader in Austin who was hiring a business development/marketing lead for URS. I was fortunate that my 12-person interview panel was willing to listen to how someone working in the beverage industry for 10 years could transfer her skills into successful business development in the energy business. I worked for that group for three years. After 91Ӱ acquired URS, I transitioned from the Process Technologies marketing lead to our new Oil & Gas Business Line marketing lead. After one year in this position, I became the Central Region Marketing Manager.

As the Americas regions evolved, I moved into my current role as Vice President, Austin Metro+ Executive where I have two focus areas. As West Region Specialist Pursuit Team Lead, I work on cross-business line opportunities, primarily for clients in our key cities. My team and I coordinate with Metro+ leads, market sector leads and client account management leads across the West Region to help position 91Ӱ for strategic capital projects that require cross-business line solutions.

My other focus is Austin Metro+ lead, which I asked my manager to be considered for. In this part of my job I meet clients, partners and navigate the geopolitical scene. I find that my two hats complement one another. I am now involved from the investigative to winning stage for major pursuits in Austin.

What was a career defining moment for you?

My career defining moment was when I started my own soda company with my husband. We left full-time jobs, sold our house and used the proceeds to take on this exciting, scary, and fun adventure in Hawaii. The experience gave me the confidence and skills to approach my marketing position with 91Ӱ in a much broader manner.

What’s something you wish someone had told you years ago?

Being scared is perhaps the best reason to try something new! I think it is important to challenge ourselves and to do what scares us – otherwise we may never learn our true potential.

What advice do you have for people who want to chart their career path at 91Ӱ? 

My advice is to understand what really drives you. Figure out which part of your job brings you the most joy and then discover how those specific skills can be applied to other career paths. Talk to people in a career path you’re interested in and ask questions.

Something I’ve noticed about careers at 91Ӱ is that people can be on the same career path, but their approach and what they do once in their position can vary based on individual strengths. It is as important what we do as how we do it. 

If not this path, what would have been your career plan B?
If living in the most remote island chain in the world wasn’t so difficult with two young children, I probably would’ve stayed in Hawaii to continue running our soda business. I loved the lifestyle, community and culture and am proud of what we created. 

I also would have loved to be a stay-at-home mom. I was raised by a stay-at-home mom for most of my life and I cherished all the time we had together. I’d also dedicate my free time to support non-profit organizations specific to cancer charities and hospice care.

Our Deep Dive series features our technical experts who give you an inside look at how we are solving complex infrastructure challenges for our clients from across the world.

This week, we are highlighting our global director of urban analytics from our Buildings + Places business and how he and his team have used their skills to help develop The Point Utah, a 600-acre innovation district outside of Salt Lake City. This sustainable and smart community is being built on the former site of a correctional facility.

During his 23 years in the industry, Avinash has worked at the intersection of technology, strategic planning, and design. Guided by a holistic, data-driven approach and focus on resiliency, he’s delivered large-scale master planning and urban design, smart city strategy, energy, and infrastructure planning projects worldwide. Avinash is the chief architect of 91Ӱ’s Sustainable Systems Integration Model (SSIM™) — an award-winning digital tool for strategic master planning at site, city or regional scales and the Triple Bottom Line Assessment (TBL™) for comprehensive multi-criteria analysis for infrastructure and design projects.

Tell us about The Point Utah. How are you and your team making this new community smart and sustainable?

Our involvement in the project began during the design competition and has continued through each subsequent stage. We’ve helped shape the different strategies for our client, The Point of the Mountain State Land Authority, to create an energy efficient, net zero, “15-minute” community. We developed a sustainability plan and a smart city strategy and are currently advising the selected developers on implementation and design refinements.

Our work for The Point focuses on optimizing water for this desert location, and in creating a net-zero carbon ready community which emphasizes quality of life through incorporating smart city, smart mobility and smart energy technologies.

Using SSIM, we assessed the sustainability performance and measured the cost-benefit of different strategies for reducing air emissions (including GHG), water pollution, water and energy use, and taking advantage of on- and off-site renewable energy resources towards achieving a net-zero carbon ready development. In this way, we’ve shaped the project by bringing the different stakeholders on board to support specific pathways for achieving sustainability and smart district goals.

Based on the SSIM findings, our team has provided design recommendations related to specific aspects of transportation, building design, ecology, waste management and water management. These recommendations include building efficiency specifications and rooftop solar integration, and the integration of secondary water for irrigation and toilet flushing systems.

The Point is also a case study for our B+P Technical Academy, where we’re educating new 91Ӱ professionals on the process and tools behind the sustainability strategies and exploring new ideas to further improve aspects such as embodied carbon.

What was a key challenge you faced while working on this project? How did you solve it?

This project represents a very progressive vision for transforming state-owned land. By turning disused space into an innovation district, it will foster technological progress for anchor institutions, such as high-tech start-ups, scientific and educational organizations, and medical innovators, while also providing mixed-use housing, office, and retail space.

The challenge is achieving the extremely high level of sustainability that is part of the client’s vision — creating a net zero community — inside the surrounding community. Local utilities were following current regulations and legislation for Utah, where goals for clean energy sources are modest. We worked closely with utilities and all other stakeholders to make sure the project had buy-in at every stage. The client group and the board were integrally involved in overseeing this project and were committed to achieving the sustainability goals but had real cost and other implementation constraints. We were challenged to explore a range of solutions that can work within these constraints.

We developed a tool to help visualize the outcomes of the various scenarios while measuring the capital expenditures and operational costs tied to each scenario. The tool was a digital twin of the project that functioned like a game board where you can take any system — water, energy, transportation — and turn dials to include or exclude different types of strategies, such as rooftop solar or water reuse, and see the performance and the costs reported out in real time.

You can also see whether you’re meeting those specific benchmarks or targets and at what cost, as well as who will bear that cost. What’s the developer’s investment? Which costs will be recovered and realized by future tenants? What if we did this instead? How can we use alternative financing? The digital tool helped us answer these and other questions and this was quite effective in building consensus with the stakeholder group.

We brought forward many innovative cost-reduction strategies, including bringing in independent energy providers as partners, reducing operating costs to residents and commercial building owners through rooftop solar, paying the cost of investment over time through a community-wide solar cooperative and promoting electric vehicle adoption in and around the community.

From a technical standpoint, our approach to reducing carbon in building and water systems considered innovative trends and sustainability certifications such as Living Community Challenge, EcoDistricts, Envision, LEED for Neighborhood Development and others.

How has this experience shaped your approach to future work?

This project validated our approach to achieving project transparency through practical, realistic engagement. Using simulations and modeling, we showed stakeholders the results of “what if” conditions and helped them reach a consensus.

We can also use this approach to meet our carbon reduction targets and make our projects more effective, while reducing the time to arrive at consensus so our clients can achieve their goals. We’re hoping to adopt this process across 91Ӱ projects. This is the aim of the B+P Technical Academy, which reaches people and projects around the world.

Another key takeaway is the power of collaboration. Our project team (including 91Ӱ’s multidisciplinary team and other experts brought in by the client) has worked as a cohesive unit to create the best outcome for our client. The expertise at 91Ӱ and our ability to tap into multiple disciplines and subject matter experts provided the foundation for this integrated approach.

How do you design buildings and spaces that meet occupants’ critical life/work/play balance while providing viable projects for developers, landlords and leasers? How do you foster interpersonal connections between in-office and remote workers and bring value to work outcomes, while also providing for adaptability that advances business, individual and community success?

Considering solutions through the lens of multiple scales — the city, the block or campus, the building and the office space — is an approach to designing offices that fosters interpersonal connections and integrates adaptability at its core, while inherently offering solutions that break down complexity. Designing to scale advances a balanced approach for occupants, while incorporating the feasibility and flexibility developers and landlords need to meet their current and future objectives. Here are four principles to consider when implementing this concept.

Context
Design in the context of multiple scales is key to delivering this essential balance. At each scale, designers consider the needs of building occupants, corporate owners, lessees, landlords and developers. To develop spaces that work across contexts, designers focus on functionality and adaptability from the broadest view — the city or location — progressively zeroing in on each level from a city block or suburban campus, an individual building and finally to the office space. Design priorities correspond to these scales, ranging from integrating into existing infrastructure and public spaces at the location scale to supporting social connections at the office space scale. 

Incorporated into each of the various scales, designers address features to enhance workforce health. This begins with evaluating city- or location-specific needs ranging from connected spaces and available surrounding services to the setting on a block or a campus where designers consider green spaces that support wellness and encourage community interactions.

Our professionals explored this concept at Commerce Metro Center in Reston, Virginia, where we developed a masterplan for 12 acres of land that integrated existing office buildings with new mixed-use buildings along a transit hub. The plan is organized around a public space spine linking restaurants and outdoor dining with hotel amenities, office lobbies, residential buildings and the metro on one seamless level, addressing many aspects of the live/work/play triangle.

Flexibility
The pandemic super-charged trends that were already in motion with many more people now balancing a hybrid schedule of in-person and remote work. Developing designs that emphasize flexibility at various scales and consider who uses the office space and how — now and in the future — benefits occupants as well as owners, developers and landlords. Design aspects can range from creating shared public spaces within private buildings to developing smart systems that maximize building occupancy and providing reconfigurable spaces that encourage personalization.

Resiliency
Climate change presents new challenges to business operations. If office spaces are not designed with resiliency in mind, they present the potential for costly interruptions or shutdowns. Incorporating forward-thinking resilient elements, at multiple scales, allows office spaces to maintain operations. For example, offices in areas prone to flooding may locate backup generators on high floors to minimize potential flood impacts or place parking at ground level so essential office functions are elevated above the flood zone.  

Equity
An increased focus on equity is leading designers to balance office and hybrid workers’ needs. Developing a distributed real estate model that improves accessibility is a primary consideration, with design solutions that provide inclusive, flexible spaces to increase desk availability if more capacity is needed on days when remote workers report to the office.

Into the future
With new workplace and workforce trends taking hold in the corporate and commercial sector, businesses are recognizing the importance of how office spaces function within broader ecosystems – physical, virtual, public, private, social, individual — that create value. A design approach that thoughtfully considers multiple scales and meets the critical life/work/play balance is emerging as a new design standard, one that will serve us all well into the future.

Our masterplan for the Commerce Metro Center in Reston, Virginia, is organized around a public space spine on one seamless level that links restaurants and outdoor dining with hotels, offices, residential buildings and public transit.

As the world looks to Glasgow for the COP26 conference on climate change, we’ll be discussing some of the changes our industry needs to make and reflecting on the COP debate on the 91Ӱ BlogJoin the discussion on social media by following us on  and . Find more information in our special COP26 edition of our “Future of Infrastructure” report: 

COP26 has begun and world leaders are gathering to agree on new carbon reduction targets. For resilience and net zero strategies to succeed in the long term, however, new infrastructure needs to be designed specifically to have a positive impact on the communities it serves.

In the UK, climate change and the levelling up agenda are forcing a rethink on infrastructure investment. That is certainly the case in Scotland, where legislative framework for emissions reduction is underpinned by a legal commitment to deliver a ‘just transition’ defined as ‘both the outcome – a fairer, greener future for all – and the process that must be undertaken in partnership with those impacted by the transition to net zero.’

As infrastructure and built environment consultants, we take different approaches to creating the equitable infrastructure needed to meet wider levelling up and net zero ambitions, from integrating the use of nature-based solutions, to placing a higher weighting on socio-economic factors in transport planning to make sure that areas of low long-term investment are brought to the forefront.

In Glasgow, several schemes of strategic importance that manage excess surface water have been initiated in the city region under the and through the collaborative Metropolitan Glasgow Strategic Drainage Partnership (MGSDP).  One of these projects is in Drumchapel, an area of deprivation identified as needing further support to tackle complicated socio-economic issues. As well as protecting areas downstream from flooding, the project needed to deliver additional social value for local people and work in the longer-term.

Looking at the flood management scheme through an environmental lens helped achieve these aims. We embedded the landscape team, which included our in-house ecologists and arborists, with the planning and engineering team from the outset. This gave us a multidisciplinary capability, meaning that we were able to use natural restorative processes to cost-effectively enhance traditional engineering solutions. For example, we knew that local people had difficultly traversing the site, so we installed robust bridges to make accessible crossing points over the Garscadden Burn, ensuring that the footpath gradients were suitable for wheelchair users.

In addition, we chose native species to replicate the natural habitat and planted an understory of native ground cover, a wetland meadow mix and trees that will need minimal intervention over the five-year implementation period. To be successful, however, this approach requires hard evidence and a very firm understanding of existing soil, hydrology, weather and climate conditions.

To achieve a just transition to a low carbon urban economy, new infrastructure must have a positive impact on the communities it serves. Within the public and political environment of delivering transformational net-zero strategies, decisions regarding new infrastructure must be transparent, robust and backed by well-researched hard evidence, of which local knowledge and community feedback must be a huge part.

The importance of continuous monitoring and evaluation of schemes, and listening to those affected, will only improve how projects are delivered in the future by building confidence and strengthening the case for change.

The increasing development of Electric Vertical Takeoff and Landing (eVTOL) aircrafts is making the case for building out a new network to support them, which will drive the opportunity to develop a new model for green infrastructure. Often depicted as flying cars, some predict these electrified “short-hop” passenger and freight aircrafts are the future of regional flight and urban taxis, holding the potential to deliver an accessible, carbon reduced transportation network that provides increased mobility in urban areas and from city to city.

What are eVTOLs? Powered by electricity, eVTOL take off vertically like a helicopter, and fly horizontally like a traditional airplane. Differing from its predecessors, eVTOLs are technology-heavy, featuring virtually silent electric motors or rotors that communicate with the batteries that power them – functions that require sophisticated proprietary software and charging technology.  As a result, we are seeing eVTOL developed by technology companies that have hired experts from the aviation industry.

This new transportation mode may improve mobility by quickly transporting small numbers of people within cities and across regions. They may also provide the rapid response logistics needed for emergency situations and increase small and rural market access.

How might they operate? There are currently two passenger transportation models, each designed to accommodate specific needs and functions. The first is based around vertistops, which is envisioned for urban locations and designed for short hops that allow for easy mobility within cities. These can be placed on existing infrastructure such as building tops or other unused spaces. The second model is compatible for intracity travel within a 150-mile range, restoring regional air service discontinued by traditional airlines due to cost considerations. Longer range eVTOL might require vertiports, stand-alone terminals, Maintenance Repair and Overhaul (MRO) operations and charging facilities within existing airports, greenfield sites or on top of other existing infrastructure. As a faster way to travel, eVTOL may replace cars, regional trains or buses, with many developers and manufacturers focusing on making eVTOLs affordable and accessible.

Vertiports: green infrastructure required. With many eVTOL developers aiming to launch by the year 2024 with the potential for established networks by 2030, these aircrafts represent an entirely new zero carbon industry that must be served by a new type of conducive infrastructure. With these aircrafts not always depending on airport access, our 91Ӱ team is currently studying the re-purposing of existing, non-traditional infrastructure such as parking garages and distribution facilities. The aircraft may also use existing logistics facilities as vertiport hubs and nontraditional rural locations, such as repurposed roadway infrastructure, as logistic hubs, significantly improving supply chain speed and remote location access.

As with all electric vehicles, eVTOL will increase energy demand. Grid upgrades will be needed to supply the energy required for battery charging and cooling. To complicate matters further, these aircrafts are expected to vary in size, each with proprietary charging methods and requirements specific to the manufacturer. Because of this, these vertiports and vertistops will require facilities to support multiple eVTOL designs and charging types.

What are the challenges in development? Federal, state and local governments are working with developers to create necessary practices, regulations and certifications, with a strong emphasis on flight standards. Given their similar range of motion to helicopters and airplanes, the industry is using those standards as a preliminary form while working to develop one overall flight standard. 91Ӱ is actively involved in this process with several agencies that are driving policy around the future of eVTOL, such as NASA and North Central Texas Council of Governments (NCTCOG). In addition, 91Ӱ holds a board position on the City of Los Angeles Urban Movement Lab, which is a dynamic collaboration between communities, local government and mobility innovators.

Establishing a new industry demands experience and insight. 91Ӱ is meeting those needs by providing expertise to private developers, airport agencies and eVTOL developers. Recognizing our focus on the future of infrastructure and global airport experience, eVTOL manufacturers are presenting their business models and technical capabilities to our design professionals to help determine feasibility in their ideas and designs. And our familiarity with eVTOL is driving airport authorities, private developers and infrastructure providers to 91Ӱ for assistance in determining potential preparations and support required to make eVTOL viable.

These efforts may seem like to be a heavy lift but with advanced technology and our integrated expertise combined with manufacturer, federal, state and local government focus, eVTOLs are poised for a smooth takeoff and with them, a more sustainable, equitable future for aviation.

In 2016, the City of Richmond, Virginia, set out to develop a master plan that would chart a path forward over the next two decades, in time for the city’s 300th birthday in 2037. With a desire to create a more equitable, sustainable future for the people of Richmond, the city recognized that a plan was needed, but was unsure of how to best to develop one. Richmond’s planning director turned to 91Ӱ’s experienced project and program management consultants and urban planners to help create a future that would manage growth and improve infrastructure and facilities, while also advancing equity and inclusion across the fast-growing city.

The result is Richmond 300: A Guide for Growth, a plan five years in the making that recently earned the American Planning Association’s 2021 Daniel Burnham Award as the nation’s top comprehensive plan. The master plan envisions an equitable, sustainable and beautiful Richmond that delivers a high quality of life for all residents. It incorporates such goals as creating inclusive housing, developing an equitable transportation network, fostering a diverse economy and supporting a thriving environment.

Here are six takeaways from this City of Richmond/91Ӱ collaboration that can help guide the development of master plans for other municipalities across the country looking to embrace a new sustainable future for all residents.

Break the mold. Typically, cities lead their master plan development, researching current conditions, developing their project scope and establishing targets before hiring a consultant to determine how to meet those goals. The planning director for the City of Richmond made the deliberate decision to move forward without these elements in place, underscoring the city’s desire for a more inclusive master plan that would consider the needs of underserved neighborhoods that historically had been shut out of these efforts.

This led to a master plan tailored to Richmond that accounted for needs voiced across all the city’s communities. While the city did not have the capacity to dedicate its personnel to the master plan full-time, 91Ӱ embedded itself within the city, temporarily relocating their offices for the project. This close relationship allowed for open, in-person discussions between 91Ӱ and city staff, cementing the team’s ability to serve as trusted advisors in a more meaningful, impactful way than would be possible with a traditional consultant.

Be open with the public. We were vocal about the process of creating an inclusive roadmap to guide the master plan’s development and sought input from the public from beginning to end. An example of this was how we formed the master plan’s steering committee. Typically, city officials appoint members for a steering committee before hiring a consultant, but Richmond wanted all voices to be heard. So, the mayor hosted a press conference where he asked citizens to apply for the plan’s committee and over 170 people expressed interest. The final committee consisted of 21 people varying widely in age, planning knowledge, and length of city residency. This diversity set the stage for an inclusive, transparent process and allowed us to create accessible, understandable content that resonated with our constituency and built community consensus.

Change the information flow. During the engagement process, we reversed the traditional top-down approach so that information flowed from the community up to the planners — a shift that allowed more people to contribute to the master plan.

We asked Richmond residents to send in their ‘Big Ideas.’ We received about 6,000 submissions, with over 900 vision statements that were then organized and brought to five working groups that were assigned to shape these submissions into draft maps, goals, objectives and recommendations. All Richmonders were invited to participate in these working groups with the expected commitment to attend all the meetings. Staff asked key technical experts from inside and outside City Hall to participate in the working groups as well, providing guidance and insight. Ranging between 30 and 50 unique members each, the groups worked with staff to fine tune the draft master plan during 15 meetings over five months. Once the working groups made their determinations, we brought the draft back for public review. The planning process began with Richmonders’ ideas and ended with their buy-in, giving all residents the opportunity to have a voice in the process and ownership of the adopted plan.

Shift gears when needed. We understood there would be times when a strategy or process didn’t work. To counter that, we built in time to reconsider and readjust, doing just that with our community engagement efforts.

We aimed to engage two percent of Richmond’s population — about 6,000 people. This target was intended to include people who are typically involved in planning conversations, such as residents who are active in civic associations, as well as residents from Black and Latino neighborhoods who have been less likely to be included in this process in the past.

When, after our first round of engagement, we lacked input from that second group, we readjusted our approach and hired seven residents from the communities we wanted to reach. These residents expanded input by using their community networks to discuss the plan and shared their feedback with the planning team, allowing us to build the inclusivity that was required in our approach.

Reach out for expertise. As a global firm, 91Ӱ has a depth of resources to draw on to address specific needs that arise during the master planning process. When developing ways to address heat islands — areas that experience increased heat within Richmond’s neighborhoods — we reached out to our colleagues who specialize in resiliency and sustainability. Based on their input, we worked with local researchers who mapped out the locations of these heat islands. The researchers found that these areas aligned with disinvested, minority neighborhoods. As a result, we devised strategies for increasing the presence of and access to greenspaces, providing greater equity for these communities.

Take action. The Richmond 300 master plan encompasses 17 goals, 70 objectives and more than 400 strategies, but unless these recommendations are acted upon, it’s only a document. Richmond is investing in bringing this plan to life. The city is rewriting zoning ordinances to deliver more parks, greenspaces and housing units throughout the city. Richmond is also using Richmond 300 to guide the redevelopment of over 100 acres of city-owned land scattered throughout the city into a blend of mixed-income housing, job-generating commercial uses and open space. And plans are in the works for a deck to be built over the interstate to reconnect a Black neighborhood that was cut off from the rest of the city decades ago. These are the first of many steps the city will take as it prioritizes equity, sustainability and inclusivity to build upon its motto – “One Richmond.”

At 91Ӱ, safety is paramount in all we do. It is an essential part of our culture and a key component of one of our core values, Safeguard. Our employees are encouraged to implement safety practices when they are on the job and away from work. At work, this can be in the form of safety planning, analyzing significant incidents or developing new procedures for changing conditions. At home this could be as simple as reporting non-work-related safety issues so the organization can learn from everyone’s experience. This all works to make 91Ӱ and our communities a safer place.

As part of our continued focus on safety, we’re demonstrating our commitment to road safety by supporting the . Simply put, low speed streets save lives. This year’s U.N. program focuses on keeping the streets and roadways safe where we live, work and play. There is considerable focus and urgency on this issue because everyone deserves the safety of low-speed, livable streets, which can have an effect on public health through the reduction of injury causing vehicle accidents and impact climate change by reducing vehicle emissions. This focus can also promote social and racial equality as a large portion of speed-related incidents occur in underserved communities.

Speeding is one of the top causes of roadway incidents around the globe, and as a globally focused organization, 91Ӱ has signed the “Streets for Life: For People and Planet” open letter that calls on policymakers to act for low speed streets worldwide, limiting speeds to 20 mph (30 km/h) where people walk, live and play.

As the world’s premier infrastructure consulting firm, 91Ӱ has helped conceptualize, develop, construct and operate transportation and roadway infrastructure projects around the world — from Honolulu to Hong Kong, and from Mumbai to Memphis to Melbourne. We have always placed a strong focus on roadway safety both in design and execution.

To achieve this, we have developed procedures and systems that include driver safety training for our more frequent business drivers, journey management planning, and design and quality checks. We’ve brought in foremost industry experts — the best and brightest from around the world to ensure that we continue to provide the high-quality expertise and delivery our clients expect from us, with an unwavering focus on safety. Road and driving safety is of particular importance to our company due to our exposure to the risk associated with it. Specifically, despite our project and geographical diversity, driving is one of the few risks that everyone is exposed to regardless of business.

Our communities are suffering from illness, social isolation, limited access to resources, unemployment and economic downturn. Yet, not all communities are experiencing these pains equally and the injustices are especially devastating for low-income communities of color. One of the most visible examples of inequity is in . We can begin to address the stark injustices facing our nation by examining the role infrastructure policy, practice and investment play in creating an equitably built environment.

As architects, planners and designers, we can use data-driven tools and analytics to create an equity-based approach to infrastructure. To be successful, this approach should include proactive development of policies, practices and strategic investments to reverse disparity trends based on race, gender, sexual orientation or income. In order to create and facilitate more equitable infrastructures and societies, cities must analyze when and how decisions are made and how these decisions impact the most vulnerable communities. Here, we share how policy, practice and investment can help reverse infrastructure inequality.

Acknowledge the structural bias and lack of social equity in the current systems

To achieve more equitable communities, we must first acknowledge the current and historical disparity in the distribution and access to infrastructure and services, which disproportionally effects certain populations. It is critical that the larger community recognize and buy in to the efforts needed to mitigate the disparity and improve equity for all. We must also set specific goals and adopt policies to set this in motion.

Develop and adopt an equity-based framework for key decision-making

Not only can we embed equity into infrastructure decisions and prioritizations, we can make those considerations and the decision process visible through an equity-based framework, or Equity Lens. By viewing development options through an Equity Lens, key decision makers can understand the equity implications of each action as well as resulting performance and cost. The Equity Lens can be applied to individual projects as well as broader programs which will allow capital planning budgets to fund projects which address equity issues and performance gaps.

Use data-driven tools to incorporate equity in infrastructure decisions

With the right data-driven tools, incorporating equity-based thinking in planning and programming projects can become an intuitive and straightforward part of the process. With automated tools to guide city engineers, planners and policy makers through an equity-based process for project and program development, we can help achieve important equity goals and outcomes. When these tools are aligned to existing workflows, are user-friendly, transparent and accessible, cities and agencies can make decisions that are not only cost effective and high-performing but can also help to reverse disparity.

Track progress over time

While we cannot solve decades of inequity overnight, we can make progress working together on small and large efforts, incrementally and persistently. By tracking progress through real quantifiable metrics, creating department and agency accountability with regular reporting requirements and review by City Councils and the public, we can propel meaningful change in our communities.

Empower the community

Communities need a real voice in this process and should participate not just through engagement and outreach for a plan, but also in setting specific equity outcome goals. A regular equity dialog between citizens, policymakers, and project engineers is essential. Discussions around education, awareness, and citizen advocacy can positively affect how equity considerations drive critical infrastructure decisions. If we can create a system for continued feedback and channel that into the evaluation framework, we can not only empower our communities but begin to create equity in our built environments.

Project Highlight:

Baltimore’s Equity-Based Project Prioritization Tool

In Baltimore, we are working with the Department of Public Works to prioritize capital investment for infrastructure projects. Which projects should move forward? Equity is the priority. By using this online tool developed by 91Ӱ, the Department of Public Works can view projects through an ‘Equity Lens’ which aggregates data such as percentage of disadvantaged and/or minority populations within the project area and enables the City to evaluate multiple locations. Each potential infrastructure project receives a scorecard for project performance, equity and combined performance and equity to help the City make the most equitable infrastructure investment choices.
