Executive Message

Our Enduring Organization

PL A N

The extreme natural events of 2017 changed the lives of hundreds of thousands of people and were among the most costly in modern history. We were on the ground following Hurricanes Harvey, Irma and Maria, after the California wildfires, and in the wake of the 7.1-magnitude earthquake in Mexico City. As we lent our expertise and resources to assist in recovery, we were reminded to take stock of what makes Thornton Tomasetti an enduring, resilient – and, yes, sustainable – organization.

“Enduring firms have a high degree of vitality, evident in their capacity to explore new options, renew strategy and grow sustainably. And the most vital firms do this quickly, with a sense of urgency.” – Tom Scarangello, Chairman & CEO We’ve seen the damage caused by global climate change up close, and we recognize the increased risk of disruption. We also see opportunities – to invest in innovations in sustainability that contribute to lowcarbon buildings and resilient design and to cultivate the agility we need to adapt, endure and thrive. In the wake of 2017’s natural disasters, we developed Our Enduring Organization, a framework for supporting and augmenting the firm’s vitality – and value for our clients – over the long term. Based on the triple bottom line of sustainability (people, planet

and profit), the framework proposes that the most effective strategy is to make meaningful investments in people and planet. Our Enduring Organization has been formally adopted as part of our core ideology, the guiding document that reflects our culture and aspirations. We are investing in people by serving as sponsors and mentors, cultivating an inclusive and diverse workplace and encouraging collaboration in a healthful work environment. We are investing in our planet by advocating for increasingly sustainable projects and reducing our carbon footprint, and we are supporting our communities by offering our people the opportunity to be avid volunteers. We are confident that these investments will drive innovation and lead to higher long-term value. This report summarizes the ways in which we are realizing our aspiration to become an enduring organization. Read in these pages how we apply our skills and values to make a better world, with better business outcomes. Our people are preventing loss of life from disasters by providing resilient and protective design and by developing sustainable and healthful buildings, innovating in sustainable engineering, and contributing to an enriching work environment and to communities in need. We are a company of 1,500 problem solvers. Whether in the field, in a post-hurricane disaster area or in the office, our people are passionate about embracing challenges and making lasting contributions.

Where Are We?

2017 Targets: Progress toward Our Goals

Our th are ma

Last year, looking ahead to 2017, we selected three targets, closely linked to the goals of our three-year corporate sustainability plan, that we hoped to meet in time for this report. Reduce electricity emissions from office operations by at least 8 percent to return to pre-2016 levels.

Achieve climate-neutral business operations

We reached our 2018 target of realizing an average per-employee footprint of 4.0 tons of carbon dioxide (CO2) two years ahead of schedule and predicted that we would continue along this path. As the company continues to expand into new locations, we are still firmly on track to meet and surpass this target when offsets are included. In fact, 2017 saw significant reductions in electricity emissions from office operations, the largest contributor to our carbon footprint. We beat last year’s target of reducing electricity emissions by 8 percent, achieving our lowest per capita numbers since our baseline year of 2013. We had also predicted a per capita electricity footprint of no more than 1.25 metric tons of CO2 by 2017. In actuality, we reduced it to 0.97 metric tons, down from 1.36 the previous year – a 29 percent decrease – attributable in part to the purchase of green power in a number of our offices.

Increase the diversity of hires for technical staff positions by 10 percent and decrease the attrition rate of diverse employees by 10 percent.

Foster workplace diversity & inclusion

Increase employee volunteerism in our communities

Last year, as part of our recently launched firm-wide Inclusion and Diversity, Innovation and Design [(I+D)2] initiative, we announced our first targets for diversity of hires and attrition among diverse employees. We’ve made progress toward these first-year goals, and have developed plans to ensure our future success. In 2017, we increased the diversity of our hires by 72 percent compared to the previous year – from 85 to 147 hires. Our attrition rate for diverse employees, including women and employees from nonwhite ethnic backgrounds, has hovered around 7 to 8 percent over the past two years. We will continue to increase the diversity of our hires and make every effort to ensure that diverse employees enjoy long, rewarding, productive careers at Thornton Tomasetti. To this end, we are revising our hiring approaches, updating onboarding guidelines and formulating strategies for retention and career advancement.

Increase the number of employees who provide service to their local communities through the company’s volunteer benefit to 20 percent. Each year, our employees take an active role in giving back to their communities through the company’s volunteer benefit program. In 2017, 18 percent of our staff logged 1,588 volunteer hours, contributing to causes and organizations that matter to them and to our industry. Though we fell two points short of our 20 percent target, we are confident that the launch of our TT Gives Back community-service umbrella program will help us meet and exceed it by next year. This initiative, which offers employees such volunteer opportunities as ACE mentorship, volunteer days and international service, doubles the hours of paid time available for volunteerism from eight to 16. As part of our ongoing commitment to helping and supporting the communities where we live and work, this program aims to foster a culture of volunteerism in all our offices while also providing team- and skill-building opportunities for our talented professionals.

hree-year plan for 2016-2019 set these corporate sustainability goals and objectives; we aking progress in most areas and are on track to meet them by December 2019.

With offsets, we met this goal early in 2016, and continued to exceed it in 2017 (see page 15).

As an adopter of the Architecture 2030 Challenge, we are working toward reducing fossil fuel use in buildings by 70 percent by 2018 to achieve carbonneutral buildings by 2030.

Realize sustainable engineering in practice

Through our Sustainability 2.0 initiative, we are making progress toward integrating sustainabledesign strategies into all our practices (see page 11).

Innovate in structural design by reducing embodied carbon

Foster workforce diversity and inclusion

We are working with our partners to increase the accuracy of embodied-carbon measurement and make embodied carbon a critical consideration in sustainable design.

Through our involvement in the Carbon Leadership Forum, we have contributed to leading research and initiatives on embodied-carbon benchmarks (see page 11).

We continue to celebrate our diverse workforce and build a strategy for increasing inclusion and diversity at Thornton Tomasetti. Since we developed this plan, our newly inaugurated inclusion and diversity initiative has made important progress toward this goal (see page 22).

Smith College Neilson Library Healthy Materials The Smith College community (Northampton, Massachusetts) envisioned the school’s new central library as a boon to the academic pursuits of its students and faculty – and as a model and agent for positive change. The sustainable design of this iconic facility, the largest capital project in the college’s history, entailed a deep dive into the industry’s burgeoning focus on healthy building materials. In 2016, the Harvard T. H. Chan School of Public Health published “The Impact of Green Buildings on Cognitive Function,” which confirmed a positive correlation between enhanced indoor air quality and higher cognitive-function scores. This will be welcome news for anyone planning to study in the new Neilson Library. Early in the design process, the college and the design team drafted a sustainability charter that prioritized energy efficiency, along with health and well-being. They then hired Thornton Tomasetti to devise and implement a road map for meeting the charter. We recommended the creation and implementation of a targeted material health and transparency initiative and pursuit of LEED Gold certification under the v4 rating system because of its inclusion of the lifecycle health impact and transparency of toxins in materials.

Manufacturers are sometimes reluctant to alter the composition of their products if they are unsure of the demand, so we suggested that the project team compose a commitment letter, or healthy materials statement. This letter affirms the architects’ intention to use healthy materials, not only in this project but in future projects as well.

The International Living Future Institute’s Red List comprises 22 classes of toxic chemicals found in building materials, among them bioaccumulative toxins, endocrine disrupters and carcinogens. These can linger for long periods in the environment and have serious implications for the health of both humans and ecosystems. Working with Maya Lin Studio, in partnership with Shepley Bulfinch, our Sustainability practice assisted the design team in specifying Red List-free products from more than 100 manufacturers and helped formulate the architects’ and the school’s commitment to eliminating toxic chemicals from future projects. Approaching the Red List can be intimidating, because it calls for the removal of approximately 800 chemicals prevalent in building materials. To kick off the healthy materials initiative, we performed a specification review to define the scope of our materials advocacy work. Then we examined the product types to identify the worst offenders with regard to human and environmental health. We also screened for cost and ascertained how critical each product type was to the character and performance of the building.

Wallis Annenberg PetSpace Life-Cycle Assessment Thornton Tomasetti employees are inveterate animal lovers, so it’s no surprise that the Wallis Annenberg PetSpace is a “pet” project of our San Francisco team. A charitable initiative of the Wallis Annenberg Legacy Foundation, PetSpace is a pet’s dream come true. The two-story, 39,970-square-foot facility in Los Angeles’ Playa Vista neighborhood includes an adoption center, veterinary services, a retail shop and a community center for education about the relationships between people and pets. This commercial-interiors project is a sustainability consultant’s delight, LEED CI Platinum certified and aspiring to the highest level of green operations and a healthy indoor environment.

“I love that the whole reason for this project is to explore the connection between people and animals, and that what happens in this space is likely to create good stewards of the environment.” – Abena Darden, Senior Project Director and Project Manager After 12 years of searching for a suitable home for the facility, the foundation selected a LEED Gold-certified office park developed by Tishman Speyer with ample public green space, ideal for pet

The Annenberg PetSpace reduced its environmental impact across all categories compared to a LEED v4 baseline. Three categories – global warming potential, tropospheric ozone potential, and depletion of nonrenewable energy sources – showed a 10 percent reduction or better compared with a baseline building.

exercise. When the architect, Swatt | Miers, introduced Thornton Tomasetti to the foundation, our experience with LEED certification, healthy buildings, green operational guidelines and life-cycle assessment appealed to the client, who valued a well-rounded approach. Committed to environmental stewardship, the foundation was inspired to retain our services – not by the prestige of a certification plaque, but out of a genuine desire to create a healthy and green space. The goal was LEED Platinum, or no LEED certification at all. We borrowed criteria for healthy materials from several certification programs and vetted every material that went into the project for its potential impact on health. We wrote policies for operational management to ensure green cleaning in all spaces and to facilitate sustainable purchasing, waste management and integrated pest management. Our meta-analysis of the materials’ health impacts enabled us to devise a color code denoting each material’s toxicity level. Those at the highest level were eliminated from use in public areas and offices. Then we delved even deeper, conducting a lifecycle assessment (LCA), which found a 10 percent reduction in three environmentalimpact categories, qualifying the project for the LEED v4 Life-Cycle Assessment Materials and Resources credit.

University of Virginia Brandon Avenue Residence Multidisciplinary “Punch” for Higher Performance As design professionals, we are sometimes given the perfect opportunity to “punch above our weight” by exceeding a project’s sustainable-design goals while keeping costs at a minimum. The University of Virginia’s Brandon Avenue Residence was one such opportunity: our design achieved significantly higher energy-reduction results than those required by the university, yet came in under the original construction budget of $46 million.

“The Thornton Tomasetti team, both Structures and Sustainability, has been the perfect partner for achieving high-performance design. Their nimbleness of design exploration and analysis is unmatched, in my experience.” – Jean Carroon, Principal, Design, Preservation and Sustainability, Goody Clancy The 208,200-square-foot suite-style student residence is the first project constructed as part of the new Brandon Avenue Green Street redevelopment, envisioned as a vibrant community linked by green space and a working landscape. UVA’s green building goal was a minimum of LEED Silver certification and an energy use intensity (EUI) of 62 kBtu per square foot per year.

Our sustainability consultants and structural engineers teamed with Goody Clancy to deliver a design that met a higher LEED standard – Gold – and achieved very low Passive House energy-use targets. We advocated for higher sustainability goals throughout the design, devising new approaches until we found one that was right for the client. Using Design Explorer™, our in-house data-visualization tool, we developed optimal exterior shading configurations and identified the best sizes and shapes for shading, from energy, daylight, and peak-cooling-load perspectives – achieving high energy savings and minimizing costs for the mechanical systems. The result was a shading scheme with a specific configuration for each window orientation. This shading solution took us a long way toward surpassing the original energy-use goals, but the window selection pushed us over the top, achieving an EUI that was 32 percent lower than the target. We recommended very high-performing windows with a U-value of .28 – about 40 percent more efficient than code windows. Aiming for Passive House energy targets, we designed for a Passive House level frame system but selected double-glazed units rather than the triple-glazed units typical of Passive House design.

employees assigned to disaster areas in 2017

Over the 2017 Labor Day weekend, many of our people packed up their cell phones, laptops and duffel bags and dived into the massive effort to provide engineering assistance to help Texas respond to and recover from Hurricane Harvey. The storm wreaked devastation from Corpus Christi in the south, northward to Houston and eastward into Louisiana. And while a number of our staff continued to help in Texas for months after Harvey, another team of engineers and architects assembled in Florida to assist with the Hurricane Irma recovery effort. Such assignments are an opportunity to develop skills and help communities heal. But they are also projects with extended durations, requiring long hours of work under strenuous conditions. About 69 employees generously set aside personal comfort to provide rapid, expert response after these catastrophes.

for charities to assist storm victims, contributed by employees and our corporate matching program We also worked with a New Jersey hospital affected by Sandy to secure funding for flood-mitigation measures through the Federal Emergency Management Agency’s (FEMA) hazard-mitigation grant program. We analyzed flood-hazard and climate-change projections and assessed the performance of the structural, architectural, mechanical, electrical and plumbing components, along with the operational and programmatic functions of the facility, at various flood levels and under a variety of projected climatic conditions. We then developed conceptual flood-mitigation options and assisted with the benefit-cost analysis. Our contribution earned the hospital a grant to fund its work to improve resilience. In 2017, we joined the Rockefeller Foundation’s 100 Resilient Cities (100RC) initiative as a Platform Partner. 100RC aims to help municipalities around the world become more resilient against growing physical, social and economic challenges. This includes connecting cities in need of resiliency services with experts who can provide them. Following Hurricanes Irma and Maria in Puerto Rico, we were called on to work with the Resilient Puerto Rico Advisory Commission and 100RC to create an actionable, scalable framework for improving healthcare resilience in the region. When a storm like Harvey hits, with unprecedented downpours and floods that cause more than $30 billion worth of damage, we are there to provide engineering know-how, aid in healing and ensure that the community can withstand future storms. We also provide financial assistance. To help those impacted by Hurricanes Harvey, Irma and Maria, our firm matched staff contributions to storm relief organizations up to a maximum of $250 per person, with a cap of $25,000, to support the American Red Cross, raising more than $40,000 for storm relief in 2017.

Protective Design Saving Lives When our protective design team is asked to lend their expertise to a project, it means that lives are on the line. Their job is to mitigate the hazards posed by potential natural or human-caused disasters, including terrorist attacks. But they also work to incorporate protection into structures in a way that enhances – or at least doesn’t detract from – a building’s aesthetics (and doesn’t obliterate the project’s budget). Developing innovative solutions and working with our Applied Science practice to strategically apply high-end analysis, they take advantage of material capabilities and push structural and façade elements to their limits. By applying this method to the 2017 protective design of the U.S. embassy in Honduras, we were able to deliver an aesthetically pleasing facility with a signature glass façade along one side, rather than the concrete fortress that the term “blast-resistant structure” might suggest. Sometimes, though, protection must take precedence over aesthetics: Recently, after a disturbed, drug-addled man plowed his car through a three-block stretch of sidewalk in New York’s Times Square, media reported that dozens of pedestrians were saved when he was stopped by three-foot-tall stainless-steel cylindrical bollards guarding pedestrian plazas along a five-block stretch of Broadway. Concerned about potential terrorist attacks, New York City had hired Thornton Tomasetti to design the bollards to protect the densely populated site.

Envision Sustainability Professionals

Established in 2011, the Embodied Carbon Laboratory, which studies the embodied carbon in our structural engineering projects and formulates strategies for its reduction, was among our first endeavors to introduce sustainable design into structural engineering. The lab’s work continues to improve our understanding of embodied carbon, internally and within the structural engineering field. Why embodied carbon? Building structures incorporate substantial quantities of steel and reinforced concrete. These materials contribute to climate change through their embodied carbon, the carbon dioxide and other greenhouse gases emitted during raw-material extraction, refining, manufacture and transportation. In a typical building, structural materials account for 50 percent of the embodied carbon.

Six years ago, we began measuring the embodied carbon in our structural projects. As an adopter of the Architecture 2030 Challenge, we realized that since our staff is composed primarily of structural engineers, the best way for us to reach its target of carbon-neutral buildings by 2030 was to reduce greenhouse gas emissions associated with structural materials. Since 2012, as a member of the American Institute of Architects 2030 Commitment, we have reported to the institute annually on the quantity of embodied carbon in our structural projects. Our 2017 data reveal that, although the embodied carbon in our projects has fallen by 39 percent since it was first measured seven years ago, reductions in project-related embodied carbon have plateaued. The average embodied carbon in our structural projects hovers at around 30-33 kgCO2 per square foot, where it has remained for the past four years. An early decrease in embodied carbon likely reflected a wider use of cementitious replacements in concrete, but the current trend indicates that reduction technology has not progressed. We continue to drive our own internal efforts to identify areas where further reductions can be made.

Thornton Tomasetti’s commitment to sustainability goes deeper than merely including it as one of our 10 practices. For any firm in our industry, true sustainability requires an interdisciplinary approach that draws on expertise from within all areas of architecture, engineering and construction. To support our goal of being one of the most sustainable firms in the AEC world, we pursue an internal initiative, Sustainability 2.0, that aims to incorporate sustainability strategies into all our practices and turns our sustainability consulting expertise inward, to the education and training of our engineers and the development of new sustainability integration tools in collaboration with our innovation incubator, CORE.

In 2017, Sustainability 2.0 helped us accomplish several important objectives:

• 16 internal and cross-practice sustainable-design workshops • 20 contracts awarded for our sustainability integration tools • 50-plus cross-practice proposals

Innovations in Sustainability: Defense and Bridge Engineering

Sustainability in Defense Engineering

Sustainability in Bridge Design

In 2017, London’s Institute of Physics awarded Thornton Tomasetti Defence Ltd. its prestigious Business Innovation Award for the firm’s cutting-edge airgun technology, which replaces the underwater explosives testing of military vessels. Navies typically conduct powerful explosive shock tests on each new or retrofitted class of ship or submarine to be introduced into service. These tests can be costly and entail many challenges, including considerable impacts on the environment and marine life. Our shock-test method was recognized as a significant environmental breakthrough, developed through a joint U.S.U.K. program, and is currently being used in trials in the United Kingdom and Canada.

Thornton Tomasetti has a long history of supporting sustainability in engineering. As a charter member of the Institute for Sustainable Infrastructure Projects (ISIP) since 2012, we made an early commitment to assist in the development and implementation of ISIP’s Envision, a rating system – comparable to the U.S. Green Building Council’s LEED certification program for buildings – that facilitates the development and maintenance of sustainable infrastructure.

In conventional testing, controlled explosives are detonated close to a vessel to verify its ability to withstand the impact of a nearmiss explosive event. Our shock-test method, alternatively, relies on seismic airguns that generate an acoustic pulse in the surrounding water. This testing can be conducted in a controlled environment such as a naval base or man-made lake, rather than in dedicated test areas of the open ocean or other bodies of water. Fish and marine mammal kill is reduced to zero, and no chemical by-products are released. Environmental organizations frequently protest against all types of naval testing, including sonar and explosive testing, which they believe can interfere with the communication of whales and other marine life, alter their behavior, disrupt their foraging and, in the case of explosive testing, trigger large fish kills. But with the shock-test method, the only by-product is air released into the water; the energy is focused directly into a ship’s structure rather than being released into the environment. This technology is a win-win: airgun testing in the United Kingdom has reduced costs by as much as 70 percent.

Envision is a framework of 60 sustainability criteria, addressing the environmental, social and economic impacts on sustainability in project design, construction and operation. By 2017, nine employees in our Transportation and Sustainability practices were accredited Envision Sustainability Professionals (ENV SP). Envision’s five categories of credits include quality of life, leadership, resource allocation, natural world, and climate and risk. The latter category dovetails well with our resiliency work (described earlier in this report).

Finding Balance Renovate or Build New? Often, renovating a structure, rather than building new, is the most sustainable choice, offering the greatest reduction in embodied carbon. However, as our analysis of Garfield House, a 40-bed dormitory at Williams College in Massachusetts, showed, new construction can sometimes be the better option. Our client, SGA, was weighing the benefits of constructing a new building vs. performing a gut renovation of the existing house, erected in 1890 with wood-framed construction and adapted over time through several renovations and additions. Thornton Tomasetti’s Sustainability, Structural Engineering, and Renewal practices, along with our geotechnical team, evaluated these options by analyzing the total carbon load – both operational and embodied. We compared the embodied carbon associated with the materials, mostly structural, that could be reused in the existing building to the embodied carbon associated with new construction. We also analyzed the predicted energy use of a deep energy retrofit compared to that of a new building designed to Passive House standards. What we found was surprising: in only 4.5 years, the new building would become less carbon intensive than the renovated building. The clincher was that the existing building was 20 percent larger than the new building. Even with a deep energy retrofit, the larger building would have required 40 percent more energy to operate.

Every two years, we conduct a carbonfootprint analysis of our offices to determine the amount of greenhouse gas emissions associated with their electricity use, waste, heating fuel, employee commuting and air travel. Our latest assessment was completed in 2016, and the next one is planned for 2018. For this report, we have updated our 2016 calculations with 2017 data on air travel and offsets, and with new data on electricity use and green power purchases for some locations. Thornton Tomasetti aspires to achieve carbon-neutral business operations by 2030. In 2012, when we first began performing these analyses, we set a short-term goal of achieving a per capita carbon footprint of 4.0 metric tons of CO2 by December 2018. We surpassed this goal early, in 2016, and have continued to exceed it, achieving a carbon footprint (with offsets) of 2.9 metric tons of CO2 per employee. Between 2016 and 2017, very little change occurred in our total carbon footprint, which remains at around 3,000 metric tons of CO2 (with offsets). However, we recorded a drop in CO2 of about 400 metric tons, attributable to an increase in our purchases of green power.

In 2014, we began purchasing carbon offsets to neutralize greenhouse gas emissions from our business-related air travel. By donating to our offsets provider, Carbonfund.org, we support renewable energy and energy-efficiency projects that eschew the burning of fossil fuels.

Because air travel is necessary for us to conduct essential business, we have chosen to offset its related emissions to meet our climate-neutrality goals. In 2017, we offset 1,317 metric tons of CO2 from more than 3,000 flights. This year, air travel represented 23 percent of our footprint, but through the purchase of carbon offsets, we were able to reduce its impact to zero.

Business Operations

Our Green Offices: Higher-Performing Offices

Part of our strategy for achieving carbonneutral business operations by 2030 is to ensure that our new offices are higher performing than spaces previously leased by the firm. Our policy of pursuing LEED certification from the U.S. Green Building Council for all new office fit-outs and major office renovations of 4,000 square feet or larger guarantees that we reach this goal. Eight of our offices have met our target of LEED for Commercial Interiors Gold or higher: Chicago (includes two projects, most recently a LEED Platinum expansion); Denver; Philadelphia; Kansas City; Los Angeles; Washington, D.C.; and San Francisco (certified Platinum under the new LEED v4 rating system). Our Fort Lauderdale office is LEED registered and expecting certification in 2018. This year, our Los Angeles office earned 64 LEED credits, making it eligible for Gold certification. As is typical for our LEED office projects, we served as our own LEED consultant, working with Koning Eizenberg Architecture, Glumac for MEP services, and Oculus Light Studio for lighting design.

Located in a LEED Platinum-certified building with access to mass-transit facilities, the project enjoyed a clear advantage when it came to earning most of the credits in the Sustainable Sites category. Low-flow and low-flush plumbing fixtures yielded a 33 percent reduction in water use, compared to baseline. Energy-efficient lighting, occupancy sensors, and daylight controls produced a 25 percent reduction in power consumption. Project materials – including carpets, countertops, and ceiling tiles containing high percentages of recycled content – were both environmentally responsible and health-conscious. More than 75 percent of the construction waste was diverted from landfills. Feedback from our Los Angeles employees has been positive, citing their appreciation of the comfortable work environment, generous daylighting and open views of the outdoors.

“We are extremely pleased to achieve LEED Gold certification for our office. We see it as another milestone toward our company-wide goal of achieving LEED Gold or better for all our offices worldwide. We are particularly proud of receiving all six available credits for innovation in design, and of our ability to cut water use by a third and power consumption by 25 percent.” – Stephan Eisenreich, Associate Principal and Los Angeles Office Director

Our Green Offices: Championing Sustainability Locally

Our growing team of green champions is helping to ensure that we reach our corporate sustainability goals – carbon neutrality, here we come! This year, more than 60 employees, in 29 locations, volunteered to be sustainability leaders, helping their offices reduce energy consumption and waste and meet carbon-footprint objectives. These green champions work to improve employee wellness and workplace comfort, organize community-service activities, and implement sustainability initiatives in ways that reflect the cultures of their offices and regions. Our Corporate Sustainability department supports them by offering guidance, resources and regular communication. In 2017, the department awarded $40,000 in grants to 12 offices in support of green champion initiatives, including ergonomic equipment, air-purifying plants, noise-masking systems, bicycles and other improvements.

We strive to continually improve the green champion program and put resources in place to guide our local volunteers. In 2017, we launched TTTRAX, a new tracking tool that helps green champions implement corporate sustainability best practices. Many such practices were initiated over the course of 2017: We started a recycling program in Austin; introduced more standing desks in Boston, Dallas, Los Angeles and San Francisco; replaced inefficient lighting in Edinburgh; and launched a composting program in London. We also placed potted plants in public areas of the New York Midtown office, eliminated paper cups and K-Cups in the New York Downtown office, introduced bike sharing in Shanghai and organized healthy staff lunches in Portland. In many locations, we arranged group volunteer days and increased employee awareness of opportunities to reduce energy use. Green champions organize events to build employee awareness of and interest in all areas of corporate sustainability. Three hundred staff members, from 25 locations, participated in our Wellness Challenge, an annual event that promotes healthy workday habits by awarding points to employees and offices for completing “wellness at work” activities. During Earth Week, green champions administered numerous in-office activities and participated in a social-media blitz via Spark, our intranet platform. Their 75 blog posts for Earth Week received more than 3,000 views. We also participated in the Building Energy Exchange’s Daylight Hour, receiving an honorable mention for our involvement (see sidebar).

Reducing Vehicle Emissions Spotlight on New York In Mumbai, India, our green champions initiated a weekly Daylight Hour, extinguishing overhead lights for at least three hours every Friday, in the areas of the office that receive sufficient daylight (see photo). This regular observance has resulted in energy savings of about 3 percent each month – enough to power three average-sized Mumbai-area homes. A survey administered by the office’s green champions showed that 100 percent of our Mumbai employees are satisfied with the amount of natural light in the office, and 75 percent favor a daily Daylight Hour.

When green champions in our New York Midtown office introduced co-workers to the Citi Bike program in 2017, backed by a corporate sustainability grant that funded 19 memberships, employees discovered that bicycling is a quick and inexpensive way to get to meetings and project sites. For these employees, biking replaced taking taxis or riding the subway to destinations in the city. A survey of our 2017 corporate ridership showed that our Citi Bike participation prevented more than 2,000 pounds of CO2 emissions, burned more than 100,000 calories and saved more than 100 gallons of fuel and $12,000 in taxi fares. The success of this test program convinced office leaders to make Citi Bike memberships a regular benefit, and in 2018, the firm will offer 30 memberships to employees in our two New York offices.

Established by Charles Thornton, one of our founding principals, the program mentors high school students, inspiring young people, many from under-resourced schools and communities, to pursue careers in building design and construction. In 2017, more than 60 Thornton Tomasetti employees, in 16 U.S. cities, served as ACE mentors. This year, members of our Chicago staff entered the Construction Industry Round Table (CIRT) National Design and Construction Competition, which is open to ACE teams from across the country. We joined forces with VDTA and Lendlease to form ACE Team 5 and selected the Barack Obama Presidential Center as our project. Our ACE mentors challenged students on the team to create a RAM model and two SAP models. The extra effort paid off – after 16 hours of meetings to design the two boards required by the challenge, CIRT announced that, of the 10 library entries, Team 5’s was the first runner-up. “All the students were pretty excited to work on the library, and it made them work even harder under a tight deadline,” said ACE mentor and Thornton Tomasetti Senior Engineer Benjamin Sexton.

We recognize that the AEC industry as a whole struggles with poor diversity, but rather than satisfy ourselves with surpassing a low industry average, we endeavor to represent the full variety of people and cultures in the areas where we work. We understand the importance of creating an inclusive and truly diverse organization, not only because it’s the right thing to do, but also because it’s conducive to innovation and more accurately reflects our increasingly diverse client base. And diverse companies achieve better financial results.

Industry average Tomasetti average BasedThornton on demographic data compiled from a number of industry indexes, Thornton Tomasetti ranks as average or above average in terms of overall diversity compared to other AEC firms. Thirty-one percent of our employees are women, and 38 percent identify as nonwhite; in these areas, our numbers exceed the industry mean. A recent internal study revealed that the average salaries of our male and female employees are approximately equal. But while we’ve made a lot of progress, we realize there is still more work to do. Our senior leadership, like those of many of our industry counterparts, is predominantly white and male – presenting a clear opportunity for improving our workplace diversity.

Inclusion + Diversity, Innovation + Design

Launched in the spring of 2017, our Inclusion and Diversity, Innovation and Design [(I+D)2] initiative supports our goal of becoming a driver of change and innovation by fostering a culture in which all our employees can realize their full potential. The initiative aims to infuse inclusion and diversity into every aspect of our firm, including how we hire, onboard, train, develop, support, reward, communicate and team with our talented professionals.

So far, this effort has produced a road map through 2020, and we have made remarkable progress toward our first-year goals: •

A 10 percent increase in the diversity of hires. Hires of women and racial and ethnic minorities in 2017 (147 hires) increased by 72 percent from 2016 (85 hires).

A 10 percent decrease in diverse attrition. The attrition rate for diverse employees has hovered around 7 to 8 percent over the last two years; this is better than the attrition rates for other employee groups, such as white males. From 2016 to 2017, we saw an already low attrition rate decrease by about 1 percent.

We want to continue to increase the diversity of hires and to ensure that our diverse employees have rewarding, productive and long careers at Thornton Tomasetti. To this end, we are revising our hiring approaches, updating onboarding guidelines and formulating strategies for retention and career advancement.

Expanding a New Community of Practice Our women’s affinity group, Women@TT, was established in 2013 at our New York City headquarters to challenge women to grow personally and professionally and to encourage them to enter the industry. In 2017, when it became a community of practice, the group tripled in size and expanded throughout our locations. Communities of practice facilitate cooperation and collaboration among Thornton Tomasetti professionals who hold a common interest, serve as a forum for knowledge sharing and innovation, and enhance our business. As a community of practice, Women@TT benefits from a dedicated corporate budget, training and a heavily supported community space on Spark, our social intranet. Contributing to the community of practice are local Women@TT groups facilitated by office coordinators. The community of practice offers a firm-wide mentoring program and supports the activities organized by the local groups, which have included lunch discussions, speakers, conference attendance and other training opportunities, community service activities, and STEM education for girls.

Employee Engagement: Cultivating a Lifestyle-Friendly Workplace

At Thornton Tomasetti, we aspire to be a career destination for talented, innovative professionals. Recognizing that we can realize this aspiration only through a genuine understanding of the diverse needs of our employees at different stages of their lives, we launched a series of topical discussions in 2017. Subjects included flexible working arrangements, unconscious bias, paid time off, building trust with co-workers, handling stress at work, being our authentic selves, and wellness.

Firm Revenue Corporate Sustainability Budget

Thornton Tomasetti’s strategic investment in corporate sustainability is unique among engineering firms in the United States. Since 2012, we have maintained a Corporate Sustainability department staffed by a corporate sustainability officer and team, who work to achieve the enduring organization vision of our core ideology by maximizing the triple bottom line of people, planet and profit.

volunteers

The department sets sustainability goals for our business operations and professional services, manages the implementation of these goals in collaboration with other departments and practices, measures our progress, and communicates information about our programs, both internally and externally. While the firm’s Sustainability practice, which provides sustainable design consulting directly to clients on projects, is distinct from Corporate Sustainability, the two collaborate with one another and with our nine other practices to achieve corporate-wide goals. Between 2012 and 2017, the firm expended about $2 million in support of corporate sustainability. Over this same period, the firm’s revenue grew by 92 percent. In 2017, Thornton Tomasetti spent more than $500,000 on corporate sustainability initiatives and staffing.

* The department employs a corporate sustainability officer and an analyst, with part-time assistance from other staff. Our 61 volunteer green champions help implement our initiatives in their home offices.
