The National Geographic M Street Building, a seven-story conventionally reinforced concrete structure with four additional below-grade levels (three of which are used for parking), spans approximately 116,500 SF. In 2021, Structura was engaged to address significant structural issues following an initial survey that revealed widespread spalled concrete, corroded rebar, and evidence of prior repair work, some of which exhibited failure.

‍

Project scope involved performing a comprehensive survey of the existing conditions and identifying areas in need of targeted remediation. Our team developed detailed repair documents outlining corrective measures for the damaged concrete and provided specifications for addressing the identified deficiencies. Acting as the Owner’s representative, Structura managed the project bidding process to secure qualified contractors, oversaw construction administration to ensure quality control during repairs, and coordinated advanced testing of the structure. This included compressive tests using core samples to assess concrete strength and chloride testing to evaluate the presence and impact of corrosive agents.

Structura’s expertise was pivotal in restoring the structural integrity of the M Street Building, ensuring its longevity while maintaining its functional and aesthetic value. This project underscores our commitment to delivering tailored engineering solutions for complex challenges.
