29 Roofs, 1 Village: Orchestrating the Mass Timber Complex at Johns Hopkins University Bloomberg Student Center

Designed by Bjarke Ingels Group and Shepley Bulfinch as a village of timber pavilions for Johns Hopkins University, the new Bloomberg Student Center is more than a gathering place; it is a feat of structural synchronization. To execute the project’s complex geometry, Clark unified trade partners, design teams, and the client into a cohesive unit, ensuring every custom detail was achieved with precision.

THE STRUCTURAL MATRIX

Defined by a system of 29 overlapping roofs, this structure relies on complex interdependence rather than the standard anchoring typical in steel or concrete construction. The result is a web of nonlinear force transfers: a load applied to one section propagates to distant parts of the structure. Success required meticulous coordination to map these loads. By engaging Clark’s design management team for rigorous constructability reviews, the project team ensured every concealed connection could withstand these intense forces while preserving the intended architecture.

PROACTIVE MEP INTEGRATION

With an exposed timber design that left no room for error, MEP coordination had to be flawless. Initial clash detection identified nearly 40,000 conflicts within the building's complex geometry. To preserve the wood's aesthetic, all penetrations were shop-cut with millimeter precision before being transported for installation. This high-stakes workflow – coordinate, fabricate, install – demanded absolute accuracy at every stage.

TIMBER: A LIVING, BREATHING MATERIAL

Wood is a porous, hygroscopic material that "breathes" with the weather, shrinking and expanding with changes in temperature and humidity. As such, marrying the mass timber structure with the steel and glass façade was a technically intricate aspect of the envelope. To maintain the façade’s future integrity, the team developed a robust waterproofing strategy with structural engineer StructureCraft. Each individual wood lamination was sealed twice for redundancy via a hidden system of air and vapor barriers. This solution provided the necessary security to ensure that no matter how the wood reacted to conditions, the building envelope remained completely sealed.

SPECIALIZED SOLUTIONS

Relentless geometric complexity and exposed timber design compelled the team to develop construction methodologies in real time. From engineering bespoke steel outriggers for complex cantilevers to piloting new acoustic materials for the great halls, and ensuring each wooden plug and cover plate was custom milled to match the wood grain surrounding it, every challenge required a novel solution. In addition, the project team developed a specialized handling curriculum, granting privileges only to certified personnel trained to preserve the wood’s pristine condition. 

Just as the structure relies on interconnected load paths, a successful delivery relies on a unified team vision. As one of the largest mass timber operations on the East Coast, the Bloomberg Student Center stands as a testament to the design-assist model. It creates a new center of gravity for the campus, providing a space for collaboration that mirrors the partnership required to build it.
