Quantitative Support for a Qualitative Foundation Reuse Assessment Tool

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 citycenter
location in Dublin, Ireland.
