Contemporary sustainable and resilient architecture encompasses design with nature, dynamic adaptability to external disturbances, smart redundancy, and changing futures, which are essential to cope with the prerequisites of cultural influences. Contributing to the existing literature, this paper presents a series of built scaled vault prototypes which integrated material performance-based approaches in computational design and advanced fabrication, utilizing locally sourced dredged material (DM) as one of the primary building ingredients. The investigated DM is acquired from Ohio’s Lake Erie harbors and one of the coastal ports in southern Louisiana. Annual sediment removal is a required task for local port authorities and federal agencies to maintain transportation waterways for economic viability. This paper discusses DM processing procedures, and granular mixture methods integrated into a number of computational frameworks to produce a range of vaulting projects from the contemporary DM-compressed stabilized tiles (DM-CST) vault to DM 3D printed vaults, considering material workability, buildability, and extrudability, as well as element’s strength and durability. Each design has to consider these factors while responding to the force of gravity in order to achieve desired structural geometry.
