A quantitative methodology for mapping project costs to engineering decisions in naval ship design and procurement
Alternative methods for cost estimation are important in the early conceptual stages of a design when there is not enough detail to allow for a traditional quantity takeoff estimate to be performed. Much of the budgeting process takes place during the early stages of a design and it is important to …

How Much Does It Really Cost? A Dynamic Approach to Building Retrofit Costs for Decarbonization Pathways
… been largely neglected: how much does it really cost? The scarcity of contemporary cost data and methods for cost prediction at the urban scale makes this question difficult, and further questions around equitable incentive programs nearly impossible to answer. This work demonstrates the concept …
