Quantitative support for a qualitative foundation reuse assessment tool

Research output: Chapter in Book/Report/Conference proceedingConference contribution


This paper provides a quantification of the inputs for an existing qualitative foundation project planning model, namely ARUP's Sustainable Project Appraisal Routine (SPeAR®) diagram. The goal is to provide an improved mechanism for designers to communicate with clients about the potential benefits of foundation reuse from a planning and environmental perspective for an individual project or group of projects based on the relative value of eight factors: (1) Site Location on Previously Developed Land; (2) Archeology and Historical Constraints; (3) Geological Conditions and Constraints; (4) Sustainability and Materials Reuse; (5) Land Value and Cash Flow Projections; (6) Construction Costs; (7) Consistency in Building Location; and (8) Approvals and Development Risk. For each category a six-point scale is provided that can be fully adopted in any community worldwide to evaluate the absolute and relative benefits between sites, even between disparate cities or countries. An example of the implementation of this modified SPeAR model is provided for a city-center location in Dublin, Ireland.
