We are excited to share the structural design of Briger Hall. Commons, and SEAS at Princeton University in a feature article in this month's issue of Structure Magazine. Link here: https://lnkd.in/e9U3CK5x By Michael Hopper, P.E., Rachel Marek. PE., William Dawson. PE As the largest project in the history of Princetor University, these buildings have it all: ⁃ Unigue two-way spanning mass-timber and stee composite "diagrids". ⁃ An innovative steel framing system constructed with paired channels and filled concrete, span over 30 ft with only 22" of total structural depth, while meeting the strict vibration criteria of the labs. - Beautiful mass-timber and acoustic DLT plank is used throughout the offices, atria, and public facing areas of the project - Exposed steel moment frames with acoustic DLT plank support the Sarofim Pavilion ⁃ Post-tensioned concrete beams and slabs are the hidden muscle that support the lab buildings above the interconnected first floor, allowina occupants tc walk unobstructed throughout the ~3/8 mile lonc complex. ⁃ Curved tendons align with the principle stress axes to help minimize the amount of post-tensioning needed to support the landscaped plaza in the Commons building It was an honor collaborating with so many of you over the past 6 years bringing these complex buildinas to life. A true world-class team. Conarats to evervone involved. And a huge thank you to our team at LERA. It takes a special group to pull off this much innovation at an immense scale. Well done! /article/hybrid-vision/

Today's visit in Madrid is looking gorgeous! The Puerta de Europa towers, or Torres KIO, are two iconic 26-story, 114-115 meter-tall leaning office buildings at Plaza de Castilla in Madrid, Spain. Designed by Philip Johnson John Burgee, and structural engineering by LERA, these were the world's first inclined skyscrapers, featuring a 15-degree tilt towards each other to form a futuristic gateway to the city.

As part of one of the first all-electric science complexes of its kind, the buildings prioritize low embodied carbon through extensive use of mass timber.

Structural engineering by LERA repost via @instarepost20 from @enneadarchitects The most recent issue of @pawprinceton features @princeton 's new Environmental Studies and School of Engineering and Applied Science complex (ES and SEAS). Designed by @enneadarchitects , it is the largest construction project in Princeton’s history at 666,000 square feet. The article explores Briger Hall, the Commons, and Sarofim Pavillion in depth. "When faculty and administrators talk about ES and SEAS, 'community' ranks high among the keywords, along with 'interaction,' 'crossroads,' and 'hub.' While the departments and institutes may be somewhat compartmentalized in different buildings or hallways, the complex was created with mingling in mind. Briger Hall boasts a range of naturally lit common areas, some large enough for departmental poster presentations and others best suited for small group chats over coffee. The Commons, centrally located, features a new interdisciplinary library and a visualization laboratory for presentations. Outside the buildings, courtyards and gathering spaces are situated among newly planted trees and grasses."

Structural engineering on the award winning Davis Center by LERA Repost via @instarepost20 from @centralparknyc Reflecting on reconnecting. 💚 Last month, we enjoyed a thoughtful conversation at the Davis Center at the Harlem Meer with @madamearchitect . Lead architect on the project Susan Rodriguez of @str.architecture and #CentralParkConservancy President and CEO Betsy Smith were joined by Madame Architect founder and editor @julia.gamolina for a discussion about the transformation of this space. Thank you to all who joined us, and we can’t wait to welcome everyone to the Davis Center this spring!

Student Commons at Princeton University, designed by Ennead Architects as part of the ES and SEAS development, is an academic building located in Princeton, United States. The project integrates teaching, research, and social spaces within a unified structural system. The building is defined by a two way hybrid timber steel diagrid that spans large interior spaces. The lattice structure distributes loads across intersecting members, allowing for reduced column dependency and increased spatial openness. Timber elements provide structural depth and material warmth, while steel components enhance joint performance and overall stiffness. The diagrid operates as both structure and spatial organizer, expressing load paths across the facade and interior. This system enables flexible program layouts while maintaining structural efficiency at a large institutional scale. © @structurecraft_ ; @enneadarchitects ; @lera_engineers ; 📍 Princeton, United States #ArchitectureLab #StructureCraft #EnneadArchitects #MassTimber #Diagrid #StructuralEngineering #Princeton

Structural engineering by LERA repost via @instarepost20 from @digsau_architecture Our work at Princeton University reimagines the historic Dillon Gymnasium, unlocking underutilized space, restoring its structural clarity, and introducing a hybrid mass timber addition that brings light, openness, and new energy to campus life. What was once a series of dormant squash courts is now a vibrant fitness and social hub—reinforcing the building’s role as a connective, inclusive center for the university community. We’re glad to see this project featured in @archrecordmag . Read the article at the link in bio. Made possible through close collaboration with a stellar team, the project reflects a deeply integrated design process from concept through construction. @skanskausa @fieldoperations @lera_engineers @vanderweil_engineers @langanengenv @nitscheng @jensen_hughes @transsolar_klimaengineering @thorntontomasetti @tlp_inc @shenmilsomwilke @mcohenandsons @rampartfacadesystems Photos: @norsworthyscott

The Davis Center designed by @mitchellgiurgola and Susan T. Rodriguez Architecture with LERA has been honored. repost via @instarepost20 from @mas_nyc Congratulations to the 2026 MASterworks Design Awards honorees! The Municipal Art Society of New York is thrilled to celebrate the winning projects and all the people behind the scenes that brought them to fruition. Hosted annually, the MASterworks Awards recognize projects completed in the previous year that exemplify excellence across the municipal arts of architecture, landscape architecture, preservation, and public art. From major civic landmarks to community centers, this year’s projects demonstrate that good design benefits all New Yorkers, contributing to the city’s resiliency, cultural vibrancy, and public health, so that we can work toward a city that is not only affordable but thriving. 🗽 MAS will celebrate these projects at Celebrating the City on Tuesday, April 21, at the Museum of the City of New York (@museumofcityny ). Tickets are now on sale.

Sunnyside Yard is back in the conversation, As policymakers revisit the potential to build over the 180-acre rail vard in Queens--one of New York Citv's largest untapped sites--the discussion highlights the opportunity to create up to 12,000 new housing units along with parks, schools, and community space. LERA previously explored the potential of the site through Loop 'N' Link, a conceptual proposa developed with daab design. The design envisioned looping residential blocks organized around interconnected public spaces, creating a vibrant mixed-use neighborhood above the active rail yard. Building over rail infrastructure presents significant structural challenges. LERA's approach focused on efficient, repetitive structural systems capable of spanning large portions of the yard while allowing flexible development above-demonstrating how engineering can unlock new urban land. Our experience with complex overbuild proiects also includes Capitol Crossina in Washinaton, DC, where a platform over active |-395 created a new mixed-use district. As the Sunnyside Yard conversation gains momentum again, innovative structural solutions will be key tc transforming infrastructure into new opportunities for housing and community. https://lnkd.in/eU4zbdEC
