Harvard - Main House Restoration
Project Context
The Dumbarton Oaks Main House represents one of the most significant historic preservation projects undertaken in the Washington, D.C. area. This comprehensive restoration effort addressed the complex challenges of modernizing a National Historic Landmark while maintaining its architectural integrity and historical significance.
Landmark Logix provided end-to-end project management for this multi-year restoration, coordinating preservation specialists, structural engineers, MEP consultants, and construction teams to deliver a seamless integration of 21st-century building systems within an early 20th-century architectural masterpiece.
The project scope included structural stabilization, complete mechanical and electrical system upgrades, restoration of historic finishes and architectural details, full ADA accessibility implementation, state-of-the-art life safety systems, and enhanced climate control for collection preservation.
Working within the constraints of an active research institution, we implemented a carefully phased approach that allowed portions of the facility to remain operational throughout construction. Our team navigated complex regulatory requirements from multiple preservation authorities while maintaining the project schedule and budget.

Delivery Challenge
Restoring the Dumbarton Oaks Main House presented extraordinary complexity at every level. As a designated National Historic Landmark encompassing 45,000 square feet, the project demanded an unwavering commitment to preservation standards while simultaneously bringing the building's mechanical, electrical, and life safety systems into the 21st century. Every intervention required careful coordination with multiple preservation authorities, each with distinct requirements and approval processes, making even routine construction decisions a multi-stakeholder endeavor.
Adding to the challenge, Dumbarton Oaks remained an active research institution throughout the 36-month construction program. Priceless collections of Byzantine and Pre-Columbian art, rare books, and archival materials had to be meticulously protected at every phase. The team was tasked with implementing full ADA accessibility within a structure never designed for it—without compromising the historic character that earned its landmark designation. A carefully sequenced, phased construction approach was essential to maintain facility operations while integrating modern life safety systems within the building's irreplaceable historic fabric.
