2023 Study Architecture Student Showcase - Part XVI

Welcome to Part XVI of the Study Architecture Student Showcase! Today, we explore the narrative of “othering” as it relates to architecture. The highlighted student work revisits norms by applying computational methodologies to the design process, positioning a tent city in an industrial zone, reimagining modernization without demanding the complete erasure of urban communities, and more. Read on for more information.

Alleviating Othering Spaces, AI Analysis, and Form in Negril, Jamaica by Caelyn Ford, Bachelor of Science in Architecture ‘23
Boston Architectural College | Advisor: Robert C. Anderson

Nothing will change until we acknowledge two truths about ourselves and the built environment; that architecture reflects, reaffirms, and legitimizes narratives of a society that ‘others’ and defines an individual’s role in society, begetting ‘othering spaces.’

That which can be physically confirmed is often prioritized over its cognitive counterpart. Design solely for the corporeal, neglecting the cognitive, is a lie of pretended humanism within the architecture profession. The thesis aims to develop a tool that expands the

capabilities of inclusive design to transform perceptual understandings of the self and ‘other’ by analyzing architecture through a neuro-phenomenological lens. This endeavor is two-fold: design for the mind and design for the other.

The thesis project investigates means of alleviating ‘spatial othering’ by quantitatively studying the building’s behavioral and emotional effect on its users to equalize the cognitive experience. Cognitive-Informed Design in architecture presents an opportunity to create paradigm shifts by applying computational methodologies to the design process. Recognizing the need for a system to connect with the end users efficiently during the design process, the potential of web-based VR, AI-generated eye tracking, brain mapping software, and biosensors was explored in this thesis to develop the design criteria.

This project was selected as the Best of Bachelor of Science degree project.

Urban Refuge: Assisting in the Development of Tent Communities Through Modular and Trauma Sensitive Design by Peter Hope, M. Arch ‘23
Academy of Art University School of Architecture | Advisor: Eric Reeder

Homelessness in the United States is a problem that disproportionately affects California. According to the World Population Review, the homeless population in California is 161.5 thousand; that is 16x more homeless people than the national average of 11.4 thousand. It is suffice to say that the issue of homelessness is not going away any time soon. Of all the cities in the United States, three of the cities with the highest homeless population exist in the Bay Area. San Jose, Oakland, and San Francisco account for 10% of the homeless population of the entire state.

The objective of this thesis is to find ways to create better spaces of refuge for the unhoused residents of Oakland, who currently call tent cities home. Tent cities are one way that the unhoused communities organize themselves. Tent cities can pop up anywhere, from highway medians to the side of the road. The selected site for this project is inhabited by a fledgling tent city that has not quite found an organizational rhythm as others in Oakland have. It is also positioned in an industrial zone which presents opportunities for city sanctioning, should the project be successful.

An installation that illustrates the movement of people to San Antonio throughout the past 300 years and beyond. The word “kal” derives from the indigenous language of the Coahuiltecans meaning “come together” and “unitas” being the Latin word for “unity.” Kalunitas expresses the convergence between four of the founding cultures that have made the San Antonio region one of the most diverse in the United States.

The Shar(e)d: Community Resilience Through Shared Spaces by Yiting Chen, M.Arch ‘23
University of Southern California | Advisor: Amy Murphy

Cities’ growth and evolution can pressure existing communities by changing the urban landscape, as seen in the Shard in London, where the construction of a glass skyscraper risks displacing the economically poor and working class. Such development doesn’t necessarily bring true social progress to the neighborhoods. A large area of glass introduced in the neighborhood almost put a death sentence on the community. This trend can be observed in many communities near central business districts.

Is there another way towards modernization without demanding complete erasure?

How can the elements of the Shard be recombined into the urban landscape in a more sensitive gesture?

How can the use of glass be more about the place and the people?

This project focuses on the development of public and shared spaces in GangxiaVillage. The synergy of public spaces can be infused into this super-dense neighborhood to ensure that the benefits of progress and development are shared fairly.

The glass will bring active changes and connections while preserving the special urban fabrics and characters of the neighborhood. A network and system of resources will be introduced to serve the residents, and this network is expected to expand and evolve when future needs arise.

This project received the USC Master of Architecture Distinction in Directed Design Research.

USC Architecture Students Built This: The Carapace Pavilion

Written in partnership with Douglas E. Noble, Associate Dean for Academic Affairs, School of Architecture University of Southern California

The CARAPACE PAVILION has been installed at Joshua Tree National Park.

The Carapace Pavilion is a project of the students and faculty of the University of Southern California School of Architecture. The project was supported by a generous grant from the PCI Foundation and was hosted during fabrication with considerable enthusiasm and support at the Clark Pacific precast facility. The project involved nearly 500 people and took almost four years from the initial sketches to the final installation. Hundreds of architecture students participated hands-on in the design and fabrication of the Carapace Pavilion, and each received tours of the precast facility with descriptions of the types of precast and the productions processes. With considerable help from the professionals at Clark Pacific, students and faculty participated in each step of the design and fabrication of the Carapace, from building the mold to the final installation.

 

THE INSTALLATION

The project was installed on June 20, 2022. A small group of volunteers arrived the day before to prepare the site. There was no construction yard allowed at Joshua Tree National Park, and installation time was limited to just one day. The Carapace was transported by Reeve Trucking on the two-hour trip form the precast yard to the site in the early morning. The large self-propelled Maxim crane and support truck arrived after dawn and completed the crane set-up prior to the arrival of the Carapace. To avoid damaging any potential native cultures artifacts, the site directly beneath the Carapace was raised approximately 14 inches by adding local fill dirt. Using a clever curved screed tool and curved side-rails, the volunteers dug out a double curved trench, matching the geometry of the foundation panel. The digging occurred only in the new raised soil that had been added to the site, and thus there was no foundations or trenching in the original undisturbed site conditions. The Carapace was quickly lifted from the truck and set onto the site with the help of rangers from the National Park Service, and several team members from Clark Pacific.

DESIGN

Students prepared a software tool to help them design this unique geometry, which is made of ultra-high-performance-concrete (UHPC). The students knew they only had one mold to work with, but wanted to create five panels of three different types. The software tool enabled the students to design the roof, walls, and floor to all be cast in the same mold, even though the panels were quite different from each other.

THE MOLD

The mold was created by students from high density foam using their 3D computer design files and a CNC machine in the School of Architecture at the University of Southern California. The mold was composed of 16 foam panels. Each panel was about three feet wide and eight feet long. To create the deep arch of the mold, a plywood egg crate form was installed on the construction deck at Clark Pacific precast plant. This allowed the students to use relatively thin foam planks for the CNC step. High density foam is relatively expensive, and the egg crate strategy created substantial savings on the cost of the mold, while also reducing waste. The 16 panels were installed on the curved plywood egg crate mold, and then epoxy and fiberglass layers provided the smooth surface finish and hid the seams of the  panels. A gelcoat was added as a final coating, and students spent many hours standing the epoxy and gelcoat between coats. The final mold resembled something like a surfboard in its’ finished surface appearance.

MATERIAL

The project uses Lafarge Holcim Ductal ultra-high-performance-concrete (UHPC). UHPC is quite different from standard concrete in the way it flows as it is cast. This required the mold to have well-sealed sides and a backpan or top mold. The backpan resulted in the project being cast blind through a funnel on the top of the mold. It was not possible to see what was happening inside the mold as the concrete was being poured through the funnel. UHPC is an especially strong structural material. While typical concrete might range from 4,000 to 6,000psi in compressive strength, the UHPC in the Carapace Pavilion was engineered at 17,000psi and the 28-day test of sample cubes revealed that the actual strength of the concrete was more than 25,000psi. Each of the five cast panels weighs between 7,000 and 9,000 pounds. At the thinnest and most critical section, the wall panels and roof panels are only two inches thick. To obtain tensile strength, tiny steel fibers, each less than one inch long and much thinner than sewing needles, are included as the UHPC is mixed in the batch plant. Millions of these tiny steel fibers were integrated throughout the mix of each of the panels. These steel fibers eliminated the need for standard rebar.

CASTING

The foundation panel was cast first. This was done for two reasons. First, the foundation panel is the smallest and uses the least concrete. Secondly, the foundation panel was intended to be nearly completely buried under the dirt of the site, and thus any flaws resulting from a learning curve would be hidden. The down-facing concrete in the mold obtained an extremely smooth surface finish matching the smoothness of the completed mold. The down-facing surface composed the interior of the Pavilion. The upward facing part of each panel had a slightly more textured finish resulting from tiny air bubbles that rose through the UHPC. UHPC has critical guidelines on the use of vibration to help settle concrete into a mold. UHPC has an excellent ability to fill the mold, and extended vibration risks having the steel fiber settle towards the bottom of the panel rather than remaining dispersed in the material. After the panels were cast and extracted from the mold, students applied a skim coat to the outer surface of each of the finished panels.

 

PANEL CONNECTIONS

The foundation panel is connected to the two wall panels using Lenton cups and high-strength grout. The wall panels are connected to the roof panels using JVI vector connectors. The JVI vector connectors are installed in a staggered configuration along the touching seams of each panel. The vector connectors are stainless steel, and the vectors are welded to each other to assemble the five panels. The project was fully assembled in the precast yard at Clark Pacific. Off-site prefabrication was critical to the project due to the limitations on site access and the extreme distance and harsh climate conditions of the project site.

TRANSPORTATION

The design team knew about the dimensions and weight tolerances for trucking, and the project is designed to exactly fit standard wide-load dimensions. The completed project weighs about 40,000 pounds, and is 42 feet long at the roof. The Carapace tapers from the 42-foot roof to only 12 feet long at the foundation. The small foundation dimension reduces impact on the site and makes it easier to fit on the truck trailer. The extended roof cantilevers to provide an expansive shade area, but also contribute to a critical high center of gravity. The high center of gravity contributed to special trucking engineering to avoid the potential for rollover or lateral loading during turns or windy conditions.

EARTH ANCHORS

With leadership from rangers of the National Park service, eight aluminum earth anchors were driven through the foundation panel to anchor the project to the site. Each earth anchor was just under four feet long, and each required a custom 5”x5” by half-inch-thick steel washer. After the earth anchors were installed, the group of volunteers back filled the interior of the Carapace Pavilion with local dirt, creating a natural dirt floor for the pavilion.

SITE DESIGN

Eventually, native vegetation is expected to grow on the east and west sides of the Carapace, helping to integrate the pavilion into the natural landscape The Carapace points due north and south, and each end of the campus provides a framed view of Joshua Tree National Park. The north opening frames a long distance view across the desert floor at Queen Valley. The south end frames a local view of the large rock formations and natural landscape adjacent to the site. The National Park Service selected a site for the campus pavilion that will eventually become a VIP campground area. VIP means “Volunteers In Parks,” and describes groups of people who camp at the park and help the National Park Service with maintenance and improvements. At some point it is hoped that the site will also include a residential education facility that will allow high school and elementary school students to come to the park and spend three days and two nights in an exploratory science curriculum to learn about the park. The Park Service is in the early stages of schematic design for this residential facility that might host 120 students and 10 or 15 faculty members. The site location is well inside the wilderness area of the National Park, and there are no services at the site. There is no water, no electrical power, no waste, and no cellphone service. The site project cannot be seen from the main road as it is hidden behind a hill of boulders, thus creating a quiet and private location for the VIP campground.
