Journey to the West Coast - ACBD2017 & SFDUG

Last week I was in San Francisco for the inaugural Advancing Computational Building Design conference featuring two days of speakers, panels, and discussions centered around the growing importance of technology in architecture, engineering, and construction. The conference placed a particular emphasis on computational design -- the use of coding, visual programming, data analytics, and other methods for more informed design and implementation.

I had the pleasure of speaking on a panel titled "Reimagining the Culture & Contractual Relationships Between Owners, Architects, & Contractors to Enable Further Adoption of Computational Design" alongside Aubrey Tucker, Innovative Technology Developer at Stantec and Thomas Whisker, VDC Project Manager at Turner Construction. While my colleagues focused on the intricacies of contracts, BIM disclaimers, and model fidelity, I took the opportunity to share how Tocci Building Co. is approaching projects differently. As Owner's Project Manager on several projects, we have the unique authority to bring the Virtual Design and Construction (VDC) team in earlier on the project for design facilitation and a simultaneous quantity takeoff and pricing process. At Tocci, computational design further enhances what we are able to do.

With more traditional project delivery VDC implements vigorous MEP/FP coordination, resulting in confirming RFIs for near-instantaneous response time and less tedious paperwork. A major advantage in a collaborative approach to project delivery/coordination is that potential conflicts are identified earlier in the project. Resolving issues before they are time sensitive and at a time when the owner can stll make decisions about the cost of the project -- rather than have those decisions made for them by construction schedule -- will ultimately deliver a final product much more closer to the initial design intent.

The key takeaway from ACBD for me was the overwhelming consensus that technology is crucial to the future success of the AEC industry. I attend several conferences per year and never have I encountered a more unified, passionate crowd of interdisciplinary professionals who are consistently pushing the boundaries of possibility and setting an example of true innovation through their work.

Later that evening I delivered one of two featured presentations to the San Francisco Dynamo User Group celebrating their 2-year Anniversary at AIA San Francisco. The SFDUG was formed with the same purpose as the Dynamo-litia Boston User Group I founded at the Boston Society of Architects to help educate and promote the use of Dynamo visual programming in local AEC communities. My presentation "Cost in Translation: Bridging the Gap Between Designers & Contractors" highlighted some of my efforts at Tocci including several day-to-day implementations of Dynamo and longer term projects such as the Sasaki WinterLight Pavilion and Union Point Comfort Station. The crowd at this event was super receptive and it was fun to meet so many new faces from the opposite side of the country!

Unfortunately there was an error recording my portion of the presentation, however you can view the slide deck HERE.

In the end it was a busy couple of days on the West Coast but I thoroughly enjoyed the opportunity to exchange knowledge and promote the importance of computational design and data-driven processes in the future of the AEC industry.

Hands-on Prototyping for BUILDing Forward

On July 27th, an opening reception was held for Autodesk’s BUILDing Forward exhibit at the Boston Society of Architects. This exhibit celebrates digital craft in the greater Boston community and highlights the research projects made possible by the Autodesk BUILDSpace — a state-of-the-art research and development facility in the Design Center.

Tocci partnered with Sasaki Associates to research and develop a prototype called WinterLight, a proposal for a temporary winter pavilion for the Rose Kennedy Greenway. Currently in the early design phase, WinterLight is a warming hut designed to encourage activation of the city’s public realm during the winter months. The structure is a semi-dome with strategic openings in customized masonry blocks, designed to shield visitors from winter winds while they enjoy the warmth of an interior fire pit. The final location of the pavilion will be located in Boston: the site is to be determined.

This project required extensive computational design from Sasaki staff to strike a balance between desired aesthetic and regularity of the blocks. Tocci’s role was to assist with geometry analysis and support the design process through construction feasibility studies. With each new design iteration, we utilized Dynamo Studio to extract total pavilion dimensions, overall block quantities, block sizes, repeatable types, total volume, total weight, and other metrics.

The BUILDing Forward exhibit provided the perfect opportunity to experiment with fabrication methods and materials for producing the unique geometry of the blocks. Sasaki chose a section of nine blocks comprised of five unique types from the overall pavilion to demonstrate scale and geometric variation. They first generated a digital model of the composition, and then processed the individual shapes into toolpaths for cutting profiles from Medium Density Fiberboard (MDF) using a Computer Numeric Control (CNC) three-axis router. They continued to cut an ingenious system of holes into the MDF sheets, lining up each piece using threaded rod. This created a negative form of each block shape for pouring concrete. Each concrete form also incorporated removable sections and a hole at the top for concrete. At this time, they sanded and coated the interior surfaces of the forms with an epoxy sealer to facilitate the release of concrete.

To prep for pouring, we disassembled the forms to coat the interior surfaces with form release. They were then reassembled on the threaded rod guides and tightened using nuts and washers.

We blended Portland cement and sand silica to create a concrete mixture that could support the compressed weight of the stacked blocks and maintain a smooth, gallery-quality finish. As each five-gallon-bucketful of concrete was poured through the top, a team tapped the sides of the forms, agitating the mixture and forcing trapped air bubbles to the surface.

At times, the form release did not properly work, forcing us to pry the blocks from their forms.

Rotating shifts of the Sasaki-Tocci team spent a week to producing the prototype, as each block required 24 hours to cure. With one last round of chiseling and sanding, all nine blocks were ready for their BSA Space debut.

The opening reception was well attended. It was inspiring to see so many creative projects coming out of the BUILDSpace and local AEC community. BUILDing Forward will be on display at the BSA until October 5th, 2017 if you would like to see our work and all the other excellent projects.

Stay tuned for more as the WinterLight project evolves into a full-scale realization.
