Vitality

A MEANINGFUL & PURPOSEFUL EXISTEN

In 2018, as we approached our 70th anniversary, Thornton Tomasetti embarked on a new initiative to ensure the long-term competitiveness of our firm. Under the guidance of Martin Reeves of the Boston Consulting Group (BCG), we established metrics for and began measuring our corporate vitality.

In 2019, to better communicate our broad involvement in pursuing both environmental and social outcomes, we changed the name of our triple-bottom-line approach from “corporate sustainability” to “corporate responsibility.”

Corporate responsibility is about recognizing that we can be a major participant in dealing with some of the biggest social issues we face. It’s about leading and collaborating and actually being in the room. We’re out there, pushing for what needs to be done, rather than just waiting for the call.”

– Tom Scarangello, Chairman & CEO

These developments are not unrelated: corporate responsibility and vitality inform every aspect of everything we do, from business ventures and employment policies to charitable activities.

BCG defines vitality as “a firm’s capacity for future growth and reinvention.”

But there is another, more full-bodied definition that closely aligns with our commitment to corporate responsibility: vitality is “the capacity for the continuation of a meaningful and purposeful existence.”

NCE

Annual Report 2018/2019

NOUN 1: capacity to live and develop // the vitality of a seed 2: energy; vigor History and etymology for vital: Middle English, from Latin vitalis of life, from vita life; akin to Latin vivere to live (Source: Merriam-Webster’s Dictionary)

Corporate responsibility is woven into the 11 factors of vitality, which include an entrepreneurial culture, diversity of thoughts, and thought leadership (click here for details). As we develop new business models and practices, vitality is a beacon that helps illuminate our future.

To be truly vital, to be included in the burgeoning global entrepreneurial culture, firms must fully engage in the digital universe. Thornton Tomasetti is increasing our investment in R&D, developing new design and analysis tools, and expanding our technological expertise.

We were among the first firms to begin tracking the embodied carbon footprints of our structural engineering projects and building tools for assessing this footprint in early design.

Last year, we started a new initiative, Doing Good Business, to deepen our involvement in projects that combine profitability with positive social outcomes.

And drawing on our years of experience in property loss consulting, risk and damage assessment, and multihazard design, we recently established a resilience group to assist our clients in preparing for, adapting to, and flourishing in an increasingly disruptive environment.

We continue to diversify our workplace through our inclusion and diversity initiative, Women@TT employee resource group, educational programs, and development of more flexible employment policies.

These and other endeavors are heightening our ability to solve the problems that impact our business success while improving the communities and environments where we live and work.

True to our core ideology, we believe that corporate responsibility helps build an enduring, and therefore vital, organization. Our objective, though, is not merely to endure, but to thrive, and in doing so, to help preserve and enrich the world around us – to enjoy a truly meaningful and purposeful existence.

ADJECTIVE 1: concerned with or necessary to the continuation of life // The heart and lungs are vital organs.

2: full of life and energy // At 80, he’s still an active and vital man.

3: very important // a vital clue

Vitality – the capacity to explore new opportunities, renew strategies and grow sustainably – is critical to the survival of firms in the AEC industry. Starting with the 11 factors identified by the Boston Consulting Group as essential to corporate vitality, our 2018/2019 annual report examines how firms, and the industry as a whole, can achieve and maintain it while balancing current performance with future health. What does vitality mean to our employees, our businesses and the world around us?

One-Year Targets for 2018

PROGRESS TOWARD OUR GOALS

In last year’s report, we announced our short-term goals for 2018. These measurable Corporate Responsibility Strategic Plan and helped move us toward achieving our thre

Reduce the growth rate of our air-travel emissions to below 20 percent.

Between 2017 and 2018, the growth rate of our air-travel emissions was just 9 percent, compared to 20 percent between 2016 and 2017. Despite this marked decline, our number of employees hasn’t changed significantly since 2016. Among the factors that may have contributed to this reduction are improvements made in 2018 to our remote conferencing capabilities, simplifying the use of technology as a substitute for travel. These included installation of new video and audio systems in conference rooms, as well as renovations of the conference rooms in several offices, where we replaced the existing audio with surround sound. A phone system introduced in selected offices in 2018 – and being rolled out to all locations in 2019 – enables employees to video- and audioconference with up to 100 people through their computers. Carbon offsets, purchased as a counterbalance to the firm’s air travel, effectively brought emissions down to zero.

Increase employee community-service hours by 20 percent.

With the kickoff of our TT Gives Back community-service program in 2017, we expected to see an increase of 20 percent or more in the number of paid hours employees devoted to volunteerism in 2018. But with 2,156 hours recorded on time sheets for community service in 2018, compared to 1,588 hours the previous year, we easily surpassed that target, logging a 36 percent increase.

The program includes volunteer days (each employee receives up to 16 hours of paid time for service to local communities), international service with Bridges to Prosperity, and involvement with the U.S.-based ACE Mentor Program. Volunteerism by employees outside of work is not recorded.

Increase the number of firms measuring embodied carbon in their projects.

Now in our seventh year of measuring the embodied carbon in our structural engineering projects, we are encouraged by the building sector’s growing interest in the impact of materials on global climate change. By amassing data from our projects, we’ve contributed to industry-academic studies on embodied carbon benchmarks. However, a complete picture of embodied carbon in structures requires data from a much wider range of firms and projects. To inspire structural engineers to contribute to reducing the impact of buildings on climate change – and to amass the range of data needed to inform that goal – Thornton Tomasetti has teamed with a subgroup of the Carbon Leadership Forum to co-initiate the Structural Engineers 2050 Challenge. In 2018, the sustainability committee of the Structural Engineering Institute (SEI) funded a study to assess interest in a Structural Engineers 2050 Commitment to annually measuring embodied carbon, and the first convening of stakeholders, funded by the American Society of Civil Engineers (ASCE), is slated to occur in 2019.

As a result of SEI’s involvement, 10 firms have so far signed a commitment letter.

Reduce our use of electricity by 5 percent and increase our purchases of green power to 25 percent of U.S. electricity use.

Our employee numbers grew by 16 percent between 2017 and 2018. During the same period, we saw a 5 percent reduction in our total electricity use. We hope to continue this positive trend, achieving another 5 percent reduction in electricity use by the end of 2019. We can accomplish this goal by continuing to conserve energy and by implementing efficiency measures in our offices, with assistance from local green champions. Introduction of new computer technology, changes to our server systems and the resulting reductions in air conditioning will contribute to these energy savings. Where we can’t reduce electricity use, we often purchase green power or Renewable Energy Certificates (RECs). For four years, we have been in good standing as a U.S. Environmental Protection Agency Green Power Partner, having met the green power threshold for a company of our size. The EPA recently raised the threshold from 10 to 25 percent of use, a goal we intend to meet by the agency’s May 2020 deadline.

Move from embodied carbon R&D to implementation; apply embodied carbon services in at least 30 projects.

For seven years, Thornton Tomasetti has been a leader in research on embodied carbon benchmarks and has amassed a large database of embodied carbon in our own projects. Over this time, we have witnessed a growing interest in embodied carbon and more requests for embodied carbon assessments. Our end goal has been to apply our knowledge to projects to reduce their embodied carbon footprint. We offer services in embodied carbon calculations and material efficiency assessment for global-warming potential. In 2018, policies and certifications began driving our clients to seek embodied carbon reduction calculations and strategies. In 2019, we expect to see steady growth in this awareness lead to more opportunities for our engineers to contribute to the reduction of greenhouse-gas emissions. Our target is application of our embodied carbon services in at least 30 projects in 2019.

Increase employee awareness of corporate responsibility programs to 90 percent through the rebranding of our department.

With employee awareness of our corporate responsibility programs now at 84 percent, we can get close to our goal of 100 percent awareness by improving communication about our goals and initiatives. A rebranding initiative begun in early 2019 will be fully launched by the end of the year. After seven years of “corporate sustainability,” we’ve given our department a new name: “corporate responsibility.” We’ve learned that “corporate sustainability” can be confused with our Sustainability practice – our green building consultants. Also, “sustainability” can sometimes be construed to specifically mean “environmental protection,” while our initiative looks across a wider view – the triple bottom line of people, planet and profit. The new wording should help raise awareness of the full range of topics and programs that make up our corporate responsibility approach, and the rebranding will communicate internally to every office, practice and department what corporate responsibility means at Thornton Tomasetti.

WE’LL DRINK TO THIS! AN ÜBER-GREEN WINERY When you work close to the land, global climate change is not an abstraction but a tangible threat to your livelihood. And if you’re like the Duncan family, owners of Silver Oak Cellars, it might inspire you to take steps to heal and safeguard your imperiled ecosystem. Thornton Tomasetti’s Sustainability practice is working with the Duncans to achieve the highest level of certification available through the Living Building Challenge (LBC) for their 105-acre site in Healdsburg, California. Silver Oak is on track to become the first winery ever to receive this über-green certification.

Our relationship with the Duncans dates back to 2015, when we helped their Oakville, California, facility achieve LEED for Existing Buildings Platinum certification.

But the program allows for certification based on the completion of as few as three petals. Why take on the more difficult challenge of completing the entire flower?

Lessons Learned While LBC doesn’t always extend into operations, for this project, materials selection was tied to wine production.

Vineyard irrigation involves considerable amounts of material, so we were challenged with finding low-toxicity alternatives to polyvinyl chloride. In addition, we had to find materials that wouldn’t corrode, affecting the wine quality.

The reluctance of some manufacturers to disclose their products’ contents complicated materials selection. Effective vetting and documentation, as well as early meetings with the contractor, Cello & Maudru, helped us satisfy the materials petal requirements.

Each LBC petal comprises two or more imperatives that must be met to complete it. To complete the seven petals required for full certification, we opted for a two-phase audit, addressing the most challenging ones, including the materials petal, first.

Petals with the most imperatives tend to be more challenging, but some imperatives are more complex than others. The biophilic design imperative, which requires examples of designing with nature, cannot overlap the beauty imperative. However, many of the biophilic design elements – including a reflective water feature that flows alongside the glass exterior, and a staircase constructed of redwood salvaged from old wine tanks – are undeniably beautiful.

In the end, a collection of modern bronze sculptures, distributed throughout the winery gardens, helped fulfill the beauty imperative.

Cross-Practice Project Showcase

PASSIVE HOUSE GRADUATES Aside from housing students, what do Garfield House at Williams College (Williamstown, Massachusetts), a residence hall at Wheaton College (Norton, Massachusetts) and the Park Row Apartments at Bowdoin College (Brunswick, Maine) have in common? Hint: These projects have all achieved close to 50 percent cost savings on energy use across the board. If you’re familiar with the Passive House energy-efficiency standard, you might have guessed it: each of these projects has met the stringent criteria for achieving Passive House certification.

reduction in energy for hot-water use

For all three projects, our attention centered on the building envelope, where smart design can substantially improve thermal comfort. But while the envelope insulation factors for these projects are impressive – ranging from R35 to R40 – our methods for attaining them varied. At Williams College, where the residence is wood-framed, we selected foam insulation for the exterior.

At Bowdoin College, where the project consists of four wood-framed residence halls, double stud walls with cellulose and fiberglass insulation offered the most cost-effective envelope. And for Wheaton’s much larger (45,000 square feet) steelframed project, the team specified five

One reason we like Pass energy. The standard isn’t always mean much. Instead per person. It pushes performance but doe inches of continuous mineral wool and spray foam in the interior stud cavity. Triple-glazed windows with highperforming frames were used across structure types.

When building envelopes are this tight, the largest contributor to energy consumption becomes hot-water use – a pervasive issue on college campuses, where long showers often afford a welcome respite from stressful all-nighters. For these residences, we recommended drain-water recovery from the showers, which, by minimizing the primary energy needed for heating water, reduced energy use by 15 to 20 percent.

A fundamental objective of the Passive House standard is to find as many ways as possible to reduce energy loads through design. Our sustainability consultants engaged experts from other fields within our firm to prevent energy leaks in challenging areas. For the projects at Williams and Wheaton Colleges, our Façades practice helped with envelope detailing and the creation of air barriers.

Our structural engineers eliminated thermal bridging, which can be one of the biggest challenges in Passive House design, by building structural thermal breaks into the design.

The Garfield House project also enabled us to experiment with phase-change materials (PCMs), which are rolled products composed of high-density polyethylene with salts and clays, to reduce peak loads, eliminating the need for mechanical airconditioning. PCMs are cool – in every sense of the word. They behave like ice, melting when warm, solidifying when cold and slowly releasing heat energy at night through radiation, like thermal mass. These materials can cool the interior of a building by 10 degrees Fahrenheit on a hot day, and provide an effective passive means of keeping the residence at a comfortable temperature.

“Passive House design is a smart choice for college residence halls. It allows us to economically take a deep dive into the details of energy performance,” said Amy Johns, director of the Zilkha Center for Environmental Initiatives at Williams College. “In some ways, achieving Passive House certification is similar to academic exploration: it takes creativity, problemsolving ability and a willingness to try new things.”

KEEPING HOMES & PEOPLE SAFE IN PUERTO RICO The past few years have been turbulent for Puerto Rico. Recovering from the devastation and later repercussions of Hurricanes Irma and Maria is still an enormous challenge for both its people and its economy. The island’s exposure to climate-related risks – including drought, extreme heat and the strong winds, heavy rainfall, and storm surges that accompany hurricanes – is significant, and experts predict that climate change will exacerbate this vulnerability. Sea levels in the Caribbean Sea are rising dramatically, and this poses serious problems for Puerto Rico’s coastal areas, where more than 2.2 million people live.

Puerto Rican housing units damaged by Hurricane Maria

houses built in Puerto Rico in 2018 without permits or professional guidance

But climate-related perils are not the only natural hazards that threaten this U.S. commonwealth. Earthquakes and landslides also pose significant threats to people, property and businesses. While it is essential to learn from the past, enhancing the island’s resilience requires that we also take into account multihazard risks and projected future conditions.

This approach to resilience capitalizes on hindsight, insight and foresight.

Providing Resilience Hurricane Maria damaged approximately 70,000 housing units. Data from the Puerto Rico Permit Management Office as of March 2018 reveals that, since Maria, about 75,000 informal houses had been constructed without permits or guidance from professionals. This is cause for concern, as studies have shown that even when authorities recommend evacuation, more than 50 percent of people seek shelter in their homes.

Keep Safe Puerto Rico is a practical design and construction guide developed by Enterprise Community Partners, the organization that formulated resilience guidelines for New York City after Sandy.

The guide, to which our global resilience team is contributing, is for preparing Puerto Rican homes for future disasters.

Enterprise Community Partners is a nonprofit that supports low-income communities. Their resilience team, headed by Laurie Schoeman, is leading this effort, in partnership with organizations that are on the ground in Puerto Rico, including the U.S. Federal Emergency Management Agency (FEMA), Puerto Rico Homebuilders Association, local architects and other resilience experts. Once the guide is complete, a training program will be rolled out as well.

Amy Macdonald and Jenifer Mahan, from Thornton Tomasetti’s resilience team, are working with Enterprise and a collaborative group of sponsors, contributing partners and funders to teach Puerto Ricans to build more resilient homes. The aim is to ensure that homes are resilient against relevant site-specific natural hazards while also considering the cascading impacts of disasters, such as power outages.

reduction in embodied carbon in our projects from 2011-12 baseline

Thornton Tomasetti’s big goal is to be the global driver of change and innovation in our industry. We pursue this goal, in part, by developing solutions for the next era of sustainable design and by creating early design tools that advance the analysis of sustainability opportunities. We find that innovation flourishes when diverse teams collaborate across disciplinary boundaries.

Our featured 2018 sustainability innovations have broadened our understanding and heightened attention in the industry to the significance of embodied carbon’s impact on a building’s carbon footprint, helped to speed up the optimization of sustainable designs, and may eventually produce a sustainable settlement on Mars. More on next page . . .

Now in our seventh year of measuring the embodied carbon in our structural projects, our Embodied Carbon Lab has seen the average embodied carbon count plateau since 2014, with a marginal increase in 2018. Minimal changes in the percentage of recycled steel, and a continued lack of market incentives for new strategies to reduce embodied carbon, may have contributed to this trend. An increase in average embodied carbon in this year’s count has likely resulted from a small sample size and the addition of different project types to our analysis, rather than greater inefficiency in structural engineering.

Business Operations

Bess Adler/Thornton Tomasetti

We aim to accomplish our goal of climate-neutral business operations by 2030 by reducing energy use locally, office by office, and by offsetting emissions that we can’t reduce. Awareness campaigns like Daylight Hour engage employees throughout the firm in reducing energy use right at their desks. Here, some energy-conservation advocates from our New York headquarters show their support for the event by lying on the floor in the shape of the Building Energy Exchange’s Daylight Hour logo – a clock showing the time of the event: noon to 1:00 p.m.

This annual campaign has inspired the ongoing use of natural lighting in many of our well-lit offices.

average per-person carbon footprint in metric tons CO2

Five years ago, we established a strategic goal of achieving carbon-neutral business operations by 2030 through a combination of reduced energy use and carbon offsets.

As an adopter of the Architecture 2030 Challenge, we also committed to the vision of climate-neutral buildings by 2030. Our internal operations goal was set to align with our external commitment, and our five-year target for progress toward this ambitious goal was to bring our 2012 annual per capita carbon footprint of 5.75 metric tons of CO2 down to 4.0 metric tons by 2018.

of 4.3 metric tons of CO2 for 2018. Our total carbon footprint for 2018 was 4,817 metric tons of CO2, the equivalent of the emissions from 1,047 cars in one year.

This is just 38 percent higher than our first recorded carbon footprint in 2012, despite a steep rise of 72 percent in our employee numbers during the same period. By offsetting emissions in areas where reductions aren’t feasible, our firm has managed to grow while keeping our total carbon footprint (with offsets) consistent since the first count in 2012, with only a 6 percent rise.

By 2016, we had reduced our per capita carbon footprint to below 4.0 metric tons of CO2, achieving our 2018 target two years early. Since then, our footprint has remained below 4.0 metric tons; in 2018, our average per capita carbon footprint was 3.09 metric tons of CO2 (with offsets).

Taking into account energy-use reductions alone – not counting offsets – we achieved a per-person carbon footprint

To measure and verify progress toward our carbon-footprint goals, every two years we conduct a carbon-footprint analysis of every sizable office with more than eight employees. We use our own carbon-footprint calculator – reviewed by external consultants – to analyze electricity use, office waste, heating fuel, employee commuting and air travel.

Sustainably Designed Spaces

OUR GREEN OFFICES

To reach our goal of carbon-neutral business operations by 2030, we’re making new offices highly energy efficient through LEED certification and other sustainable-design rating systems. Since 2012, our policy has been to pursue U.S. Green Building Council LEED certification for all new office fit-outs and major office renovations of 4,000 square feet or larger.

Seven of our offices have met our target of LEED for Commercial Interiors Gold or higher: Chicago (two projects, including a LEED Platinum expansion); Denver; Philadelphia; Kansas City; Los Angeles; Washington, D.C.; and San Francisco (LEED v4 Platinum). Our Fort Lauderdale office is LEED registered and is anticipating certification in 2019. And soon, we expect to earn our first Living Building Challenge (LBC) materials petal for our Denver office’s ultra-healthy new space at 303 17th Avenue.

Healthy activities like hiking are part of our everyday culture in Colorado, and our staff care about wellness. The focus of the LBC materials petal on healthy materials is a great fit for our staff and an effective demonstration of our sustainability services.”

– Jeffrey D’Andrea, Denver Office Director

By obtaining sustainable-design certification for our offices, we’re leading by example and enabling our employees to learn important lessons by applying their knowledge to internal projects.

But why seek LBC instead of LEED certification? Increasing numbers of our projects are pursuing this stringent certification, which is relatively new in the field of sustainable design. As we strengthen our expertise in this area, the Denver office move and fit-out presented an ideal opportunity. The LBC materials petal is comprehensive. To earn the certification, every product was evaluated for its environmental and human health impact, and the design team completed detailed market research to find the most sustainable products available. Staff from our Sustainability practice served as the project’s sustainability consultants.

OUR GREEN CHAMPIONS

In 2018, 84 employees – in all but our smallest offices – served as local corporate responsibility advocates.

Green champions help us meet local energy-conservation and efficiency goals, reduce our waste footprint and achieve other environmental objectives.

They also work to improve employee wellness and workplace comfort, organize community-service initiatives, and implement firm-wide corporate responsibility initiatives locally. Our Corporate Responsibility department provides them with resources, targets, guidance, and networking and ensures strategic alignment with corporate goals.

corporate responsibility grants awarded in 22 locations

The Corporate Responsibility Grants Program gives green champions and office directors the opportunity to undertake initiatives that fall outside standard office budgets. Since its inception in 2012, the program has awarded $155,000 for local projects.

In 2018, it awarded 27 grants, totaling $45,000. Inspired by these grants – and motivated by their passion for creating positive change – last year, green champions initiated a number of improvements in their offices. These include embracing eco-friendly dining by purchasing reusable tableware, dishwashers, and organic and healthy snacks; lighting fixture improvements for greater efficiency; wellness rooms and yoga classes; and even the certification of our Los Angeles office as a Green Business by the City of Los Angeles.

One way our green champions move us toward our goal of 100 percent employee awareness of corporate responsibility programs is by organizing events. In 2018, 29 of our offices participated in Daylight Hour, an international social media campaign organized by the Building Energy Exchange. Our 2018 participation earned Thornton Tomasetti the Globetrotter Award for the company with participation by staff in the “farthest flung” international offices. We saved more than 540 kWh of electricity by turning off the lights and using natural daylight.

COMMUNITY SERVICE

250+ volunteer days logged in 2018

2018 was an exciting year for community service at Thornton Tomasetti, including, among other things, the full implementation of all parts of our TT Gives Back community-service program.

Established in 2017, this three-pronged program aims to build leadership skills, provide new opportunities for teambuilding and business development, and increase our social impact. It has expanded opportunities for employees to engage in volunteerism during the workday, and it included our first annual international service trip with a multioffice team of employees.

Building on existing volunteer programs, TT Gives Back opened up new opportunities, including international service to the most disadvantaged communities. In our first year of partnering with Bridges to Prosperity, we aided in the construction of a suspended footbridge that serves 1,170 people in the remote community of Boca de Lura, Panama. This memorable two-week experience, described by one employee as “the best project” of his engineering career, not only linked an isolated community with schools, markets and healthcare, but built strong bonds among the members of the Thornton Tomasetti team from different locations and practices.

To increase our impact, in addition to the contribution of staff time and bridge sponsorship, the firm made a year-end donation to support the operations of Bridges to Prosperity. The organization used these funds as a match for individual contributions toward their

2019 goal of building 30 more bridges to serve 88,000 people in need.

While one prong of the TT Gives Back program entails serving disadvantaged communities far from home, another involves volunteering in the local communities where we live and work.

Employees receive up to two “volunteer days” each year, which they can use to benefit a variety of causes, including homeless shelters, Habitat for Humanity, conservation organizations and more.

The third prong continues our decadeslong legacy of cultivating the next generation of AEC professionals. For 26 years, the firm has supported the U.S.based ACE Mentor Program, established

by Founding Principal Charles Thornton, through funding and volunteerism.

Thornton Tomasetti has the highest participation rate in the ACE Mentor Program, compared to firms of a similar size. Read more and share!

In 2018, more than 250 employees (20 percent) volunteered their time to help local organizations, families and schoolchildren. Our initial goal for TT Gives Back was a 20 percent increase, after one year, in local communityservice hours. These include hours spent mentoring high school students in STEM topics through the ACE Mentor Program and days of community service in employees’ local communities. In 2018, compared to our 2016 benchmark, we saw an increase of more than 19 percent in hours contributed to the ACE Mentor Program and realized a 53 percent increase in employee use of volunteer days.

PHILANTHROPY

Our charitable giving continues to grow each year, and has nearly doubled since 2013. In one year, our total contributions rose by 8 percent. During 2018, we donated $393,432 to aid disadvantaged students, families and communities and to help mitigate climate change.

We continue to support our legacy areas of philanthropy, including the ACE Mentor Program and the Salvadori Center, which provide STEM education to schoolchildren. About one-third of our monetary donations go to the Thornton Tomasetti Foundation, which sponsors numerous grants, fellowships and scholarships and distributes funds to a variety of AEC-related nonprofits.

Newer areas of philanthropy include direct collaboration with Bridges to Prosperity, through our TT Gives Back initiative, as a corporate partner on a bridge-construction project. Our separate end-of-year donation served as a match, enabling the nonprofit to secure funding from additional sources. We are in our fifth year of donating to Carbonfund.org to offset our air-travel emissions by supporting renewable-energy and energy-efficiency projects.

Local offices contributed to 26 percent of our charitable giving, supporting a variety of causes that are meaningful to their staff and community members.

For example, this year we gave to the Global Orphan Project and the National Multiple Sclerosis Society, and backed Canstruction competitions to collect food and raise money for local food banks.

On a calm day in September, members of our Women@TT employee resource group from the Boston, Massachusetts, and Portland, Maine, offices hosted a networking sail across Boston Harbor.

Aboard the Liberty Clipper, a modern replica of the fast schooners of the 18th century, our staff were joined by more than 50 clients and colleagues. This event formed memorable connections between our staff and other professional women from the Boston-area AEC industry and provided an opportunity for our rising women stars to connect with established industry leaders.

We made our greatest strides in 2018 in improving inclusion for women. According to the 2018 Structural Engineering, Engagement and Equity (SE3) survey published by the Structural Engineers Association of Northern California, a disparity still exists between the advancement of women and men in the engineering industry. Thornton Tomasetti’s second annual pay parity report indicates a promising rise in the number of women moving toward leadership roles in our firm.

We have improved our retention of women employees – in part, by offering enhanced benefits like expanded parental leave and a global flexibility policy. And our women’s employee resource group (Women@TT) engaged more than 300 women in local and firm-wide programs to educate, support and elevate them. Read more and share!

Mentorship opportunities for women grew in number, attracting the participation of women at many levels within the organization. Women@TT offered traditional long-term mentoring, as well as shorterterm programs for discussion around specific topics. A women’s mastermind retreat, also hosted by Women@TT, engaged women at the associate level to explore opportunities for growth, with the goal of supporting and retaining talented women at a pivotal stage in their careers. A new Senior Women’s Leadership Development Program helps prepare women at the senior associate level and above for leadership responsibilities and provides a forum for upper management to act as mentors for emerging female leaders. As we go forward, we continue to improve these programs for women and plan to expand best practices for other underrepresented groups.

Read our interview with Gabrielle Bullock, principal and director of global diversity at Perkins+Will.

In our second year of (I+D)2 , we identified areas that were important to increasing inclusion and diversity – such as work-life balance and learning – and developed goals and strategies around them. This exercise, under further development in 2019, will inform the firm’s fiveyear plan. We also used our social intranet to shine a light on diversity, developing a diversity calendar to highlight upcoming events and sharing lessons and perspectives from leading diversity advocates.

Thornton Tomasetti strives to build an inclusive environment in which our people are respected for who they are, and are free to thrive. In pursuit of this vision, in 2017 we launched (I+D)2 (Inclusion and Diversity, Innovation and Design) firm-wide and expanded ongoing programs to promote the advancement of women.

A LIFESTYLE-FRIENDLY WORKPLACE

In 2018, new and enhanced benefits supported our goal of providing a lifestylefriendly workplace. We expanded our parental leave benefit for U.S. employees, adding four weeks of paid leave (up to 10 weeks total) for mothers who have recently given birth. All parents who are primary caregivers continue to receive up to six weeks of paid leave. In response to feedback from staff, we initiated a global flexibility policy that defines “core hours” and, with some exceptions, allows employees to work according to a schedule that best suits their needs.

Increased promotion of our expanded health-and-wellness programs contributed to a 24 percent rise in use of our fitness reimbursement benefit for U.S. employees.

Our wellness program, offered in collaboration with Cigna, launched a new page on Spark, our social intranet, greatly improving its visibility. The 2018 program included wellness fairs in several of our larger offices – giving 390 employees access to massage therapists, meditation sessions, flu shots and wellness checks.

Seminars on topics such as financial wellness, ergonomics and nutrition, along with healthy snacks, were offered in all locations.

The global Wellness Challenge, an annual event, helps catalyze awareness of and interest in our wellness program. This year’s challenge, our fourth, boasted more participants than ever, with 33 percent of employees, across 26 offices, signing up. Participants earned points and won prizes for themselves and their offices by completing wellness activities over a fourweek period. Read more and share!

Our corporate responsibility grants program promoted health and wellness at the local level by providing funding for a variety of items, including plants to improve indoor air quality, furniture for “wellness rooms,” ergonomic equipment and yoga classes. Originally supported by this program, and now a standard feature in our offices, standing desks continue to provide better work-station comfort.

Thornton Tomasetti is committed to the success of our employees, and nurtures their professional development throughout their careers. We offer formal training programs to all our staff, both online and through instructor-led sessions.

Last year, our online catalog included 455 courses, most of which offered continuingeducation credits. These were completed 3,760 times. Members of our staff conducted 21 hour-long courses covering best practices and case studies. We tapped into our engineers’ expertise to devise training that supports continuous improvement in our design-analysis approach, and we are adapting our largest custom projectmanagement training initiative for delivery in the United Kingdom in 2019. Through our Quality Assurance initiative, we also launched a program that conveys valuable lessons learned from past projects.

Spark, our social intranet, facilitates grassroots knowledge-sharing. On average, 62 percent of our people made use of Spark each month. Communities of practice (CoPs) – online affinity groups that provide an employee forum for exchanging information and advice on a variety of topics – foster idea generation, communicate best practices and inspire innovation. Our CoPs grew in number from 15 to 22, with a combined total of 525 members.

In 2018, we hired our first knowledge manager, who is leading the effort to expand our knowledge-sharing capabilities.

In line with our firm’s value of “challenging people to grow,” we promoted 309 employees to more advanced positions, and our intern program helped 149 people get started in their careers.

Our commitment to increasing diversity at our highest leadership levels inspired our women’s employee resource group to host a mastermind retreat in support of women’s career development. The retreat focused on women at the associate level, a pivotal stage in which responsibilities change considerably. What we learned will serve as a basis for career development programs during 2019.
