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.

Data For Understanding Cities
Blake Shaw, Head of Data Science - Foursquare

For those of you who have never heard of Foursquare, it was originally a mobile device app for sharing locations and activities with your social network - occasionally creating the opportunity for chance encounters when two friends find themselves in the same vicinity. Nowadays Foursquare has evolved into a powerful mechanism for tracking human behavior. With the exponential rise of people connected to the internet via mobile devices, how will the constant production of "data exhaust" be harvested and what can it tell us? How does a city behave as a living organism? What is the most popular activity on a hot summer day (answer: getting ice cream)? Foursquare continues to examine correlations among human behaviors and asks how we can better interact with the buildings we inhabit. Everyone experiences an environment differently but how can data derived from countless previous experiences be used to inform future experiences and provide valuable recommendations? Data is the key to optimizing the potential for enjoyable experience.

Data for Building Insight - Panel Discussion
Brian Cheng, Designer & Associate - HDR Architects Jennifer Downey, National BIM Manager - Turner Construction Peter Raymond, CEO - Human Condition

This session started off with each person sharing a little bit about technology efforts at their companies. At HDR they are utilizing a combination of a custom dashboard and parametric modeling to analyze health care program and massing test fits. In addition, advanced model sharing and co-location methods enable instantaneous coordination with engineers and consultants. Turner presented an example of how LEAN strategies, aggressive coordination and scheduling, thorough communication, all combined with robust project data have made a significant impact at their company and played a large part in the world record setting concrete pour at the Wilshire Grand in LA. Human Condition demonstrated a construction safety vest that tracks body position, biometrics, and worker location. With the further development of wearable technology, real-time information can be gathered on every worker at the construction site and a holistic safety culture can be established through the incentives of exemplary performance.

During the discussion it was pointed out that currently in the AEC industry there is a culture of "commodification of mistakes," meaning that contingencies are written into contracts, numbers are carried for unforeseen costs, and there is a standing assumption of labor inefficiencies and injuries on the job. How can BIM be better utilized to mitigate these costly errors and how can new technologies improve job safety and productivity? Perhaps tools like clash detection and co-location make for a more streamlined design and construction process. Furthermore, BIM as a platform needs to become a mode of communication between project constituents and facilitate a timely transmission of data. Another question that emerged was how can decades of on-site construction knowledge and experience be gathered and implemented much earlier on in the design and documentation phases? Strategies like pulling seasoned construction workers into the coordination meetings and using tools like a company intranet to archive knowledge and solutions were suggested. It is also imperative to seek feedback and document the process in order to ensure continuous improvement.

Data for Retail Roll-Out
Scott Anderson, VP Global Corporate Store Planning & Development - Estee Lauder Companies Melissa Miller, Exec. Director Corporate Store Planning & Development - Estee Lauder Companies

This team is responsible for identifying new opportunities for brand positioning within retail department stores and carrying out the requisite construction. After years of managing projects through email, Word, Excel, and Gantt charts it became apparent that tracking the transfer of information across multiple platforms was incredibly inefficient. The team set out to construct a custom dashboard that managed all communications, actions, specific information, and progress by project. Now project managers and company executives can enter the system at any time and review progress. The new system has enabled transparency and drastically reduced the duration of projects.

Data for Indoor Positioning
Andy Payne, Senior Building Information Specialist - CASE Steve Sanderson, Partner & Director of Strategy - CASE

With the emergence of indoor positioning systems that triangulate mobile device location using Bluetooth, wireless, and GPS, a team at CASE Inc. has embarked on a project to harness indoor location data. Using a custom app created to track employee movement throughout the workday, CASE recorded one month of data and produced this analysis. From this data, it was determined that only 2/3 of space is being actively utilized in this BRAND NEW office the company just moved into. In addition, some of the program was not being used as originally intended or seldom used at all. Disregarding the potential for future company growth, CASE has wondered how the results this post-occupancy analysis would have affected the planning of the office layout prior to signing their lease. This led to a larger conversation about the opportunity for implementation in design. For example, how can this technology be applied to doctors and nurses in a health care setting to monitor their daily routines and learn more about the way spaces are truly used? The potential for better understanding of human behavior and the development of theoretical simulations to analyze building program is very exciting.

Data for Building Buildings - Panel Discussion
John Moebes, Director of Construction - Crate&Barrel Doug Chambers, CEO - FieldLens Todd Wynne, Construction Technology Manager - Rogers-O'Brien Construction

These three gentlemen discussed coordination and the use of data to avoid significant delays in project timeliness. At Crate&Barrel, many of the Autodesk software products are used on a small project team to design and build new stores throughout the world. Careful documentation allows the Crate&Barrel to bring the procurement of steel and materials in-house at a significant cost savings and drastically reduce the possibility of mistakes in the field that affect valuable components of retail design. FieldLens is a task management product that allows construction managers to better orchestrate the construction process. With the ability to assign particular tasks to specific individuals, save notes and images, review a 3D model and construction documents, and track workers on site, a superintendent can keep much better tabs on aspects of the job and managers can have a continual progress update on how the work is progressing.

Data for Galactic Growth
Roni Bahar, Exec. Vice Presedent of Development & Special Projects - WeWork

WeWork is a company that offers coworking office space worldwide via an hourly or monthly subscription model. In the last four years they have seen exponential growth leading to construction on an unprecedented scale to accommodate demand (12 new office locations in just the last year). In an attempt to manage this frenzy they have embraced modular construction as a method for standardizing construction technique, aesthetics, and material cost regardless of location or contractor. The kitchen units, cubicles, conference rooms, bathrooms, and common area furniture are all modular components built in Revit complete with detailed finish information, material takeoffs, and construction details. As much of a well-oiled machine the procurement and development arm of WeWork is, it was fascinating to hear that the one lacking component to the process is hard data and feedback. With such rapid growth and a relatively small project team, the company is building offices faster than research can be conducted to determine the success of the spaces they are producing. In the next few years as the WeWork begins to catch up with the pace, it will be interesting to see how they aggregate data to substantiate the success of the experience beyond sheer number of offices and dollars.

The Glass Cage

I recently read the book "The Glass Cage: Automation and Us" by Nicholas Carr and was inspired by his message of the growing advantages and dangers of technology, particularly pertaining to design and architecture.

Carr says, "Technology is as crucial to the work of knowing as it is to the work of production. The human body, in its native, unadorned state, is a feeble thing. It's constrained in its strength, its dexterity, its sensory range, its calculative prowess, its memory. It quickly reaches the limits of what it can do. But the body encompasses a mind that can imagine, desire, and plan for achievements the body alone can't fulfill. The tension between what the body can accomplish and what the mind can envision is what gave rise to and continues to propel and shape technology. It's the spur for humankind's extension of itself and elaboration of nature. Technology isn't what makes us 'posthuman' or 'transhuman', as some writers and scholars have recently suggested. It's what makes us human. Technology is in our nature. Through our tools we give our dreams form. We bring them into the world. The practicality of technology may distinguish it from art, but both spring from a similar, distinctly human yearning."

Fusion 360 Digital Fabrication Workflows:

This course highlighted several features of Autodesk Fusion 360, a program that facilitates easy manipulation of 3D geometry otherwise difficult to achieve in Revit. After exporting a conceptual mass family from Revit to Fusion 360, an undulating wall form was created that could then be imported back into Revit, populated with curtain wall using adaptive components and rendered in a perspective street view with Google Maps background. That same form was imported into a program called Meshmixer that provides advanced options for preparing an STL file for 3D printing and allows you to apply custom supports. Altogether, the integrated workflow across several software platforms was relatively seamless and the course exhibited proof that very complex and customized geometry to be created in Revit for any project type.

Building a Good Foundation with Revit Templates:

Members of the architecture, engineering, construction and manufacturing industries gathered for this round table discussion about best practices for starting a project in Revit. Two methods were compared, the use of a Template File and Default Project. At Shepley Bulfinch, we use a template file at the outset of every project that contains a minimum amount of views, families and general standards to provide a good starting point. A default project has the advantage of carrying much more initial information including pre-placed families and objects but requires a significant time investment to keep the content current. Overall, the common sentiment in the room was that template files are easiest to maintain and offer the most versatility for any project type. Additionally, it is preferable not to “front load” Revit models and start out with unnecessary file size when one of the biggest challenges among all projects is keeping the model as small and responsive as possible.

Energy Analysis for Revit:

Are you familiar with the native energy analysis tool in Revit (hint: it’s under the Analysis tab on the ribbon)? This tool has the potential to be very helpful for early feedback to help drive the design. The task can be farmed out to the cloud for faster processing and to post reports for multiple options. For more in-depth analysis, the Revit model can also be exported to GBSxml format and opened in Green Building Studio, a cloud-based energy simulation platform. Relatively specific configurations are required within a model for the analysis to run successfully and one of the predominant takeaways of the course was the emphasis on modeling with energy analysis outcome in mind from the start of the project.

Challenges of LEAN Design and Computational Analysis:

This very engaging roundtable discussion examined the emerging role of computational analysis and generative design to help make more efficient design decisions. The keynote address at the beginning of the conference featured the use of "machine learning algorithms" where information and constraints are entered into a computer and simulations are run to determine an optimal design outcome. To start this session, we identified wastes and ineffective behaviors within each profession and in the collaboration process between. After a predictable round of architect-bashing, the question was proposed: "Does computation and simulation allow us to come to confident solutions earlier in the design process and reduce waste?" If existing condition information, user requirements, code constraints and many of the other variables that influence the design process can be programmed to generate permutations, is this a promising direction for the future of the profession? The group came to the conclusion that computational analysis and simulation will never be reliable enough to deliver a comprehensive design solution but may be helpful in providing direction at challenging moments in the process.

Practical Uses For Dynamo Within Revit:

Dynamo is a visual programming environment that allows you to make custom changes within Revit and extract information otherwise unattainable with the native program features. The program utilizes a user-friendly graphic interface to make adjustments within the Revit API (the "back end" which contains all the building blocks for how the program functions). This course demonstrated many entry-level uses for Dynamo including:

• quickly making changes to all instances of a family type in a model (example: adjusting the offset height of all columns at once)
• advanced family geometry (example: controlling profile order to create cantilevered and wrapped swept blends)
• wrapping structure along curved surfaces
• generating separate finish floor on top of slab automatically from room boundaries

Utilizing Revit Models for Architectural Visualization:

This course covered work flow and best practices for exporting a Revit model to the Unity 3D, a game engine that enables real-time visualization and walk-throughs. The first step is preparing the Revit model for export by cropping down only what you need with a section box and turning off unecessary categories in Visibility Graphics. Export the model to FBX and import it to 3DS Max where materials, cameras and lights are applied. Lastly the model is imported into Unity where perspectives, walk-throughs and animations can be utilized. In summary, Unity 3D provides a compelling presentation piece that may appeal to some clients but it is important to consider the time investment that goes into the preparation process.

Dynamic Energy Modeling:

An energy and environmental analysis consultant presented a multitude of methods for assessing daylighting, wind, weather, energy consumption and other performance characteristics of a design. Specific tools covered included eQUEST, Green Building Studio, Autodesk360 Lighting Analysis, raytracing and raycasting, Rushforth Tools Library, Autodesk Ecotect and more. Although these programs were generally too advanced for the level of in-house analysis we use at Shepley Bulfinch, I enjoyed learning about numerous ways information can be extracted from Revit and used to help inform the architectural design process.

Revit + Dynamo = The Building Calculator:

Beyond parametric modeling and making tweaks within Revit, Dynamo can be used to extract much of the information stored within a model. By using an "export to excel" function, areas, quantities, dimensions, room lists and so much more can be exported and analyzed with the powerful tools Excel has to offer. Schedules can be created, complex building calculations can be scripted and automatically updated upon every change within the model, or checks and balances for code and zoning can be integrated to produce reports. Items can then be adjusted, renamed or resized to push back into Revit from Excel and make direct changes to the model. Dynamo provides a giant step forward in the pursuit of harvesting the full potential of BIM.

The Great Dynamo Dig: Mine Your Revit Model:

With all this excitement surrounding Dynamo, did you know there is also a SQL export function? This allows for the creation of a much more comprehensive database that can be thoroughly organized using database management software and mined for analytics and appealing visual graphics in Tableau.
