Abstract
The adoption of digital fabrication with concrete (DFC) has the potential to bring sustainability, productivity, and process innovation to the construction industry. However, DFC adoption towards market-ready construction systems is lagging due to a lack of understanding in matching its technology capabilities with the needs of potential adopters. This paper describes a DFC Evaluation Framework, analyzing current advancements in DFC through a Conceptual Framework Analysis. The framework is focused on the inputs, process parameters and outcomes of a given technology solution independently of the enabling technology type. It can be used to classify and compare DFC technologies along their systemic characteristics, which are both technical and non-technical in nature. The DFC Scoreboard, an interactive tool to match DFC technologies with the needs of prospective adopters, is developed and tested based on the framework. The paper discusses how the DFC Evaluation Framework and Scoreboard offer one of the first systemic overviews of DFC adoption, with the capability to match technology capabilities and user needs in the technology adoption process.
