City: Boston

A new landmark for Boston grounded in technology, innovation and sustainability

Modern and memorable, Terminal E is an iconic front door for the airport and region

Born from the colors of Boston on the outside, flowing and operationally efficient on the inside, the newly revamped Terminal E at Boston Logan International Airport is an elegant and welcoming introduction to the city. The international terminal — with its distinctive, prismatic red roof and sleek, undulated façade — opened in August 2023. This redevelopment project added 320,000 square feet and four new gates to the building, plus 70,000 square feet of renovated and replanned functions within the existing terminal, including new ticketing, baggage and U.S. Customs and Border Protection (CBP) facilities.

A central design feature of this terminal is its iconic red roof. The prismatic red paint, dubbed Boston Red, subtly changes color depending on the light and was created specifically and exclusively for the project — marking the first time prismatic paint has been used on an airport façade. The roof’s form, gently sloping over the building’s south side façade, reveals panoramic views of the downtown Boston skyline. The terminal’s north and west offer unfettered views to the airside and East Boston waterfront.

The modernized terminal — encompassing major renovations along with new amenities and conveniences — was designed with a focus on incorporating sustainability, improving operational flexibility and enhancing the passenger experience for the eight million international passengers flying through Terminal E each year.

As prime consultant and lead master architect, AECOM delivered full architectural and engineering services, collaborating with vision architect luis vidal + architects and construction manager at risk Suffolk, to bring this alternative delivery project to life. This complex expansion program involved building through, expanding and enveloping existing buildings on a fully active airport apron. The program was completed in multiple phases without affecting continuous airport operations or building safety and security.

Redefining the passenger experience

With the volume of travel and travelers continuing to increase, Massport’s top priority with this project was to develop a terminal space that elevated the reputation of Boston Logan Airport for providing passengers with a best-in-class experience.

In addition to expanding Terminal E’s square footage and increasing the number of gates from 12 to 16, our team renovated the main terminal, adding a soaring, multi-story central great hall that creates an elegant, memorable place for passengers to relax, work or shop. New elements, such as a consolidated, state-of-the-art passenger security checkpoint, upgraded baggage systems, and intuitive wayfinding and digital signage, make the travel journey seamless, easy and relaxed. Expanded concessions, diverse seating areas and new airline clubs give travelers more options to spread out and be comfortable.

To promote an inclusive passenger experience, specialized amenities include comfortable seating with power for charging devices, work bars, high-quality concession offerings, mother’s rooms, companion care rooms and pet relief areas. A key first for Boston and the region, Massport and AECOM collaborated with the New England Center for Children to create an all-ages sensory room that addresses the needs of passengers who require a visual and auditory separation from a busy terminal. The space includes an airplane simulation room that provides a full-scale replica of the interior of an airplane, using video, auditory and tactile replications of the plane environment to assist passengers with transitioning to a new and perhaps unfamiliar environment.

Improving operational flexibility

When designing the new Terminal E, we focused on ways to incorporate features that would not only improve flexibility but enhance operations and increase efficiencies. One innovation in particular stands out – flex gates.

Several of the new gates are designed in a way that can morph to simultaneously accommodate a range of international, domestic or pre-cleared flights, which is especially important during peak hours where inbound or outbound flights outnumber gates. For example, the gate piers — vertical circulation from the terminal to the plane — can be instantly and easily adjusted to process simultaneous operations, including combining international or domestic arrivals or departures at the same gate — all without jeopardizing security protocols or the separation between international and domestic passengers. This includes flexibility on the apron for a mix of aircraft parking positions with dual lead-in lines, visual docking guidance systems, and fuel pits for a wide range of wide-body and narrow-body aircraft.

As an added element of flexibility, ground boarding or deplaning operations can even be processed from a hard stand where passengers are bussed to or from the terminal to a remote aircraft parking position. At Terminal E, the gates are “flexed” to accommodate these simultaneous operations by deploying two jet bridges are dividing the gate piers into two separate enplaning/deplaning zones. The function is further enhanced at the departures level where an easily accessible exit lane is provided for domestic or pre-cleared arrivals when it is not necessary for passengers to go through customs and immigration on the terminal’s lower mezzanine level.

Curbing a carbon footprint

Sustainability played an integral role in the development of Terminal E. Resilient to environmental factors, environmentally conscious and designed to withstand a changing climate, the terminal’s design adopted advanced building systems and renewable energy, with its fundamental shape and orientation specifically crafted to reduce its carbon footprint.

The design team used extensive modelling to determine the building’s shape to manage solar gain, harvest daylight throughout the year and generate power with building integrated photovoltaics. The terminal’s south-facing façade contains 5,500-square-feet of photovoltaic glass that turns sunlight into electricity. Dynamic glass on the terminal’s north side automatically self-tints when necessary to reduce glare and reflected solar gain. The new central great hall was designed around the yearly sun path, blocking sun in summer and inviting solar gain in the winter, with continuous daylighting to all public spaces bathing the terminal in natural light. Further, the precisely designed displacement ventilation system efficiently delivers a comfortable interior environment in both the summer and winter months. Due to these features, Massport expects annual electricity usage to be reduced by nearly 10 percent.

Modelling also helped evaluate the terminal for better management of carbon emissions and energy use. The meticulously detailed and constructed façade is well-insulated and airtight. The roof and building envelope are calibrated to respond to the myriad of weather conditions that New England brings, including high winds and capacity for a 500-year storm, whether it is in the winter or the summer. To minimize greenhouse gas emissions, recycled materials were incorporated throughout the building and natural resources, renewable energy sources, and advanced interior and exterior building systems were carefully integrated, including a solar-ready roof.

Incorporating social value principles, the terminal supported initiatives that have tangible results for the surrounding community. The building’s shape was designed to serve as a noise barrier, shielding the sound of planes and airport operations from the nearby East Boston neighborhoods. Airplanes at the gate are powered directly from the terminal building without any fuel use, which allows the engines to shut down — eliminating idling noise and significantly reducing hydrocarbon consumption and plane exhaust — further benefiting the airport’s urban environment. Electrification stations are provided for apron equipment in support of a fully electric terminal.

These energy efficiency efforts create the largest and most sustainable terminal building at Logan International Airport, with a 25-percent reduction of quantified energy use above the Massachusetts Energy Code — a significant accomplishment considering the embedded energy burden of this particular building type. Charting a path to net zero, Terminal E is targeting LEED Gold status from the U.S. Green Building Council.

A longstanding partnership

Designed to be efficient, modern and memorable, the revamped Terminal E supports Massachusetts’s regional economy by accommodating international demand while minimizing community and environmental impact. Executed by AECOM in partnership with Massport over several phases spanning fifteen years, Terminal E is the latest in a series of projects completed by AECOM at Logan International Airport. Our two decades-plus collaborating with the agency to provide full-service architecture, interior design and engineering services encompass five major terminals at Boston Logan, including the Terminal B optimization project which opened in 2021. With the opening of Terminal E, the close partnership between AECOM and Massport continues its successful track record advancing initiatives that benefit the people and communities of Massachusetts.

AECOM is the prime consultant of a joint venture and responsible for assisting with program management, engineering and architectural design, public participation, environmental compliance, and the Federal Transit Administration (FTA) New Starts support for the $2.1 billion project. The Silver Line is a bus rapid transit (BRT) line that will provide service from Dudley Square and Back Bay to the emerging South Boston waterfront and Logan International Airport. The Phase III tunnel segment, located within the densely developed downtown, represents a critical link between Phase I (in operation from Dudley Square to downtown) and Phase II (completed in 2003), connecting South Station to the waterfront and the airport. The Silver Line, when fully operational in 2016, will be Boston’s fifth transit line.

Environmental Clearance – AECOM managed preparation of a final environmental impact statement/report under the National Environmental Policy Act (NEPA) and the Massachusetts Environmental Policy Act (MEPA) to respond to project changes since the predecessor transitway project was approved in 1994. Key environmental issues included compliance with Section 4(f)/106 due to the extensive historic and archeological resources within the alignment corridor, including the Boston Common; urban design interface of surface elements of the underground stations and tunnel portal; and construction-phase impacts associated with underground construction in the densely developed business and residential urban area, including the city’s Chinatown neighborhood. To respond to the environmental and community issues, to enhance ridership, and make the project more cost effective, a number of alternative alignments and portal locations were developed. An extensive community-focused public involvement program was also implemented to involve the environmental justice organizations in the project area.

New Starts – An important early task was preparation of the annual New Starts report to FTA. To prepare the submission, the entire MBTA finance plan and capital program was evaluated and included developing a cost allocation model, a 30-year sources and uses of funds analysis (capital and operating), ridership forecasts, and fare revenue forecasts. As a result of the team’s efforts, the project earned a “recommended” rating from FTA. AECOM will continue to assist the MBTA with its annual New Starts reports to FTA and the request for a full funding grant agreement (FFGA) for the project as it moves toward construction.

Engineering and Architectural Design – AECOM is also leading engineering and design of the project. The first phase in the FTA’s New Starts process will be to prepare preliminary engineering drawings, outline specifications, and develop a construction cost estimate that will provide a greater level of certainty in the overall program budget. Through this phase of the project, the tunnels, station structures, and architectural features will be designed to a preliminary level. Although the fire/life safety systems, facility systems, and transitway systems may be procured under a performance-based specification, these systems will also be engineered to a preliminary level to more accurately assess construction cost. Preliminary construction staging and maintenance and protection of traffic plans were prepared to address the constructibility and associated costs in the construction estimate.

Opened in 1923 as an airfield for the Massachusetts State Guard and the Army Air Corps, Logan International Airport is the 18^th busiest airport in the country. In 1943, the airport was named after Lt. General Edward Lawrence Logan, a Spanish-American war hero from South Boston. Today, the airport has six runways and handles more than 30 million passengers annually. AECOM has a long history with the airport, having provided services, including the Terminal B Renovation on behalf of United Airlines and a state-of-the-art fueling system.

Terminal B Renovation

United Airlines was determined to give their customers a superior travel experience at Boston’s Logan International Airport following a merger with Continental Airlines, one of the nation’s largest commercial airline companies.

Through a partnership with the Massachusetts Port Authority (Massport), United Airlines consolidated operations by upgrading Terminal B. The new, 200,000 square-foot section accommodates facilities and amenities for existing customers and those acquired from Continental Airlines — prior to the merger, both airlines were located in separate terminals.

As lead designer for this US$160-million project, AECOM provided architectural, interior and structural design, project controls and resident inspection services to create a comfortable and relaxed ambiance for customers and self-service technologies that streamline the usually hectic traveling process, including:

• 10 modified gates;
• Improved passenger security checkpoint and ticketing areas;
• A state-of-the-art baggage handling system;
• Self-tagging baggage kiosks;
• Automated self-boarding gates;
• Customer service center allowing employees on site to help passengers requiring assistance;
• Electronic charging stations in every chair in the departure lounge;
• And flight information displays in boarding areas.

Opened to the public in April 2014, Terminal B offers a comfortable and relaxed atmosphere dedicated to enriching the experience of flying with United Airlines.
