The DART is a living, evolving tool. Much like a well-designed building, it will alter and adapt to meet future needs over time. RTKL has established a group of external experts and advisors, who are leaders in the field, to contribute to this resource.

Frequently Asked Questions

How did The DART come about?
In early 2013, RTKL began developing The DART as part of a larger set of online tools we call The PDD Toolbox. In addition to The DART, The PDD Toolbox also includes Smart Start, an interactive guide to the Performance-Driven DesignSM process, and The DASH, a repository of project performance metrics that allows us to compare our work against both internal and external benchmarks.

Shortly after our internal release of The PDD Toolbox, we realized that releasing The DART as a public resource would have a much larger impact on improving the value of the built environment than it could if reserved solely for RTKL designers. We hope you agree and that The DART becomes an invaluable tool in your design process.

What are your future plans?
RTKL is working to expand The DART with additional design strategies, relevant case studies and supplemental research and information sources. We also plan to address how a strategy’s impact may differ according to variable factors such as project type and region. The development of “shopping cart” functionality is high on the list giving users the ability to collect strategies and customize an approach that is specific to their needs.

How can I get involved?
Incorporating feedback from users of The DART is essential to maintaining its relevancy to the Performance-Driven DesignSM process. Please contact us with any suggestions for topics, additional resources or case studies that our users might find useful.
