The LaGuardia Pocket Parks project required intense coordination and involved Customworks by Tournesol’s entire project management, engineering, quality and production teams. After initial evaluation, the engineering team created a list of questions, concerns, and design suggestions. The modular custom planter elements, created in RINO modeling software by Supermass, were imported into the Customworks parametric design & manufacturing software, which required some correction and refinement to complete the design. No two planter sections were the same. Shortly after we were brought in, Supermass and the owner chose a standard Tournesol bench design (the Esplanade Collection) on which to base the customsteel benches. After several working group meetings, the final details for installation and assembly were worked out based upon Customworks suggestions, and the models could be finalized for fabrication. In order to meet the project time requirements, the molds used in casting the GFRC components were carved in foam using a multi-axis CNC foam cutting robot. The modeling software allowed us to virtually create the four- or five-part tools, which could be directly uploaded into the CNC system. The traditional method of hand-building plugs, then casting tools would have doubled the time to complete the job.
