Project Overview
BKBM provided structural engineering services for the phased renovation of the historic Marcel Breuer-designed library at Collegeville, MN. The project aimed to sensitively modernize the facility while maintaining the integrity of its iconic architectural features.
Project Highlights
- Elevator Shaft Addition:
- Designed and coordinated the insertion of a new interior elevator shaft, which required precise penetration of existing concrete pan & joist and waffle floor slabs.
- Structural Modifications for Modernization:
- Provided steel framing supports multiple locations to enable safe removal and reconfiguration of existing concrete masonry unit (CMU) and cast-in-place concrete walls, accommodating new architectural layouts and accessibility improvements.
- Analysis for Mechanical Upgrades:
- Analyzed original concrete buttresses and floor plate slabs to facilitate new mechanical penetration without compromising the structural performance or historic integrity of the building.
