As digital technologies continue to evolve, the ability to encapsulate domain expertise and design principles into software applications has become a game-changer. These computational design tools automate complex tasks, optimize processes, and incorporate industry best practices and regulatory requirements, empowering firms to deliver high-quality, consistent, and cost-effective solutions to clients. Furthermore, the ability to rapidly prototype and iterate allows for the exploration of novel approaches to address intricate challenges. 

The previous two articles in this series explored the leadership perspectives and computational engineering processes involved in developing these powerful tools. Through the lens of the Office Space Automator (OSA) project, we gained insights into the managerial considerations and the critical role of computational engineers in translating domain knowledge into robust computational logic. 

This series aims to provide a comprehensive understanding of the practical application of Computational Thinking (CT) principles in the development of computational design tools. By analyzing real-world challenges and strategies employed in the OSA project, we offer a blueprint for project teams to follow as they embark on their own computational tool development initiatives.  

Building upon the logic derivation phase explored previously, this article shifts focus to the tool development phase, led by computational designers. We will delve into their responsibilities, workflows, design principles, and application of CT to transform derived logic into functional, user-friendly computational tools. Examining the OSA project through this lens provides valuable insights for others looking to develop innovative tools. 

1. Case Study Overview 

The OSA project, central to this series, was a pioneering initiative by Henderson Engineers’ Innovation Department. It aimed to develop a computational design tool to streamline and optimize the office space design process in Revit. The project’s objectives directly aligned with Henderson’s core values and strategic goals that emphasize innovation, efficiency, and delivering exceptional value to clients. 

Specifically, the OSA project had two main objectives: to formalize the firm’s collective business logic and expertise across various engineering disciplines into a computational framework, and to create a user-friendly tool that could generate optimized office space layouts based on user inputs and Revit model information while adhering to building code standards and industry best practices. 

The project followed a structured approach divided into two distinct phases. The first phase, logic derivation, involved computational engineers working closely with technical experts to translate their domain knowledge into a formal computational representation. This critical phase was explored in-depth in the previous article, “CT 202 – Computational Tool Development for Computational Engineers.” 

Building upon the foundation established during logic derivation, this article will concentrate on the tool development phase and the instrumental work of computational designers. By examining their responsibilities, workflows, and application of Computational Thinking principles, we aim to provide valuable insights for professionals in this field to develop innovative computational tools that drive efficiency, accuracy, and customer satisfaction within the AEC industry.
