Team: Julieta Alva, Nick Krahn, Richard Mohammed

Developing a fluency with parametric design and an understanding of the implications robotic fabrication has within the built environment was the goal of this seminar. Using Grasshopper 3D parametric modelling software and UBC’s 8-axis Kuka robotic area, we were challenged to design and build a wooden structure using a repeated structural component that could come together without the use of fasteners or glue.

Over two months, our team of four designed and constructed a 1 m tall geometric structure maded up of a repeated diamond extrusion joined by a box-joint. The primary challenge of the design and fabrication process was ensuring that the unique orientations of each interlocking panel was accurately accounted for in the parametric code and the specific angles in each box-joint connection could be machined by the robotic arm on a specified thickness of material.

[fig 1.1] 3D model of final design, Maverick Chan, 2022.

The design began with the intention to create a human-sized lantern articulated with different aperature sizes extruded and skewed in different directions, similar to an amethyst gemstone. The inital massing began with a simple capsule form segmented using a diagrid. Aperatures were extruded using the centerpoints of each diagrid. Its size, extrusion length, and direction were parameterized and varied using a random generator.

Challenged to construct our structure without the use of glue or hardware, our group developed a box-joint connection that leverages the capabilities of both parametric design and robotic fabrication. The angles of each panel relative to adjacent panels were precisely captured by Grasshopper and used to machine the unique connection at each joint. Panels were cut out of 3/4” marine grade plywood using the robotic arm.

Client: Blueridge Chamber Music Group

Commissioned by the Blueridge Chamber Music Group, the brief for this Design+Build project was to construct a portable amphitheater that can be transported and played in different public parks. The challenge of this project was to design a structure that could not only naturally amplify the musicians in an open park but also and be easily disassembled for transport.

The final design includes five curved wooden shells built atop a steel trailer. The two outermost shells pivot around a steel frame to extend their reach and resonance beyond the stage. I worked closely with a team of 15 students over three months refining the design, sourcing materials, managing construction, and ensuring the project was completed on time.

The design process was an interative one, as we worked through and combine different ideas within the group. Construction of each shell first began with assembling a skeleton system of structural LVL ribs cut by the Kuka robotic arm. The structure of each shell was then clad with overlapping plywood panels that were manually bent and fastened to match the shell’s curvature. The exact shape of the final design was dictated through sound reflectance simulations compelted in Grasshopper 3D. Once the shells were cladded, they were lifted onto and secured to the railer bed. A steel frame was also installed to support the two rotating fins and provide structural stability.

UBC Third Space

August 2021 - Present

2022 US Solar Decathlon Build Challenge Supervisor: Dr. Adam Rysanek Team: UBC Third Quadrant Design

Third Space is a 1200 sqft building on UBC campus designed by Third Quadrant Design, a team of UBC students in architecture, engineering, and business. Competing in the 2022 Solar Decathlon Build Challenge held by the US Department of Energy, Third Space is a design-build entry for the highperformance single family home category. Conceptual design for the project began in July 2021 and has since received a $50,000 USD prize from the Solar Decathlon to proceed with the build, successfully granted a building permit from UBC, self-fundraised the entirety of the project, and formed partnerships with the pillars of Vancouver’s building industry. Construction of Third Space began in July 2022 and will be complete for competition in April 2023.

The design combines work and efforts from architecture and six engineering sub-teams including structural, mechanical, electrical, civil, building science, and energy. I acted as the Architectural Team Lead for the project, leading a team of 10 design students through design development, schematic design, construction documentation, and construction administration. Iterating the design continuously with different engineering teams, communicating with consultants, build partners,and sponsers, I developed an appreciation for the extensive amount of coordination and collaboration necessary to bring a design concept to reality.

[fig. 3.1] Perspective Theall, 2021.

The goal of the proejct is to design and construct one of the first buildings in Canada to be net-zero carbon within its lifetime. In order to achieve this goal, the building drew on principles of passive design. The dual sawtooth roof line optimizes passive daylighting and natural ventiliation, minimizing the operational carbon needed to run mechanical and cooling systems throughout the year. The adaptive re-use of recyceld building materials in the project and the use of carbon negative hempcrete as insulation and thermal mass were primary strategies for minimizing the project’s emobided carbon. All design decisions were tested in energy models, daylight simulation, and life-cycle carbon analyses.

The program of the building also had to serve dual functions. For the competition, the project will be built and judged as a single family home. However, post-competition the building will be converted into an institutional study space and living-lab for UBC applied science students to use. Ensuring the design of the building could adequately meet both needs and be flexible enough to adapt to both cases was an exercise in problem solving and systems thinking.

Addressing food security in the midst of an ever changing and unstable climate was at the core of our design prompt for a community center in Fraser Lake, British Columbia. Challenged to design a large building without the use of any mechanical systems for heating and cooling, our proposal sought to interweave agriculture and harvesting into indoor program and minimize our impact on the site through different passive design strategies. Thermal strategies such as organizing active and sendentary programs along North and South facades respectively and incorporating indoor grow spaces as additional sources of heat in the winter drove the project’s design philosophy.

Design decisions were made with the goal of minimize the building’s operational and embodied carbon. Selecting efficient and local construction methods and low-emboided carbon materials made up a large portion of the project and created a feedback loop that informed the design process. An energy model was also created of the building in ClimateStudio to ensure that our ventilation strategies, building envelope, and internal heat sources could adequately maintain comfortable occupant temperatures throughout the year. The result was the centralized growth center that blurs the line between indoor and outdoor that creates a space for learning, play, and growing year-round.

Imaginary Spaces

Carleton University Studio First

Instructor: Mustafa Faruki

This project explores architecture as a tool for storytelling. It explores how spaces are defined by the history and experiences of the people who inhabit them. Using disassembled piano pieces as a starting point in our design thinking, we were challenged to abstract its geometry, functional logic, and even texture to imagine a new spatial narrative for the artifact. I began this process by isolating the mallet head for exploration, manipulating the shape further and imagining it in different repeating and alternating patterns. This led to the development of two unique structures. Overlaying different context over these structures using trace paper became an exercise in imagining the different worlds this architecture could populate and the many stories they can tell.

[fig. 5.2] Form and narrative exploration, Maverick Chan, 2019.

[fig. 5.1] Piano hammer material exploration, Maverick Chan, 2019.

Interpretations of the structure at different scales and the context they existed within varied widely amongst friends, reinforcing that architecture is personal and molded by memories and personal experiences. Some imagined a skytrain from one of the structures and others saw a remote research facility. The narratives and context layered overtop the two imagined structures helped inform the design process and the architectural exploration in bringing these imaginary spaces to reality. Repeating the process of reconfiguration and re-imagination with the proposed spaces, the drawings were collaged through repetition and alignments. The result was another abstraction of the original piano piece open to interpretation.

Transmission of airborne disease is a concern in many indoor spaces. Studying the role building design and ventilation play in both the spread and mitigation of aibrone viruses was the primary goal of this research project. Using Computational Fluid Dynamic (CFD) software, I construct fluid simulations that map airflow and aerosol spread within a multi-bed hospital room. Interpreting this data to develop recommendations for building retrofits and COVID-19 intervention planning is especially meaningful as it highlights the impact that the built environment has on health and the responsibility to design safe spaces.

The nature and transmissibility of COVID-19 has not only highlighted the importance spatial considerations play in determining our health, but also the ways in which economic and social inequality amplify disproportionate rates of infection and death. Community housing buildings in Toronto typically suffer from issues of over-crowding. In a time when social distancing is paramount, the ability to visualize and study whether a relationship exists between crowded housing and infection becomes important to explore and analyze.

Using GIS and COVID-19 data from the City of Toronto Open Data Portal and the Ontario Ministry of Health, this project aimed to plot Toronto community housing buildings against COVID-19 case rates by neighbourhood using Grasshopper 3D, Excel, Illustrator, and QGIS.

PAUSE THE DRAW

Prior to starting my Masters of Architecture, I worked for 2.5 years as a Clinacal Research Assistant with the Hematology/Oncology Clinical Research Group (HOCRG) at St. Michael’s Hospital in Toronto. I gained valuable experience coordinating the ReBDI Study, a quality improvment project in the Medical-Surgical Intensive Care Unit (MSICU). The objective of the project was to reduce repetitive blood draws in the MSICU and the potential harm this can have on patients. Critically ill patients in the ICU receive intensive amounts of blood tests and monitoring each day, many of which are essential for their care. However, mounting evidence suggests that a significant proportion of blood testing in the ICU is reflexive and unnecessary. This project thus involved carefully understanding the primary drivers for for reflexive blood testing and implementing effective change strategies into daily pratice to minimize patient harm.

Two research projects were completed as part of this project. Analzying historial laboratory data, we were able to identify that ICU phlebotomy was associated with hospital acquired anemia and need for red blood cell transfusion. Building upon this research and implementing several different change strategy into the MSICU over two years, we successfully reduced ICU phlebotomy averages and sustained this change to this day.

Abstract

Background

Reducing unnecessary diagnostic phlebotomy in intensive care: a prospective quality improvement intervention

Intensive care unit (ICU) patients are at high risk of anemia, and phlebotomy is a potentially modifiable source of blood loss. Our objective was to quantify daily phlebotomy volume for ICU patients, including blood discarded as waste during vascular access, and evaluate the impact of phlebotomy volume on patient outcomes.

Change strategies included education, ICU rounds checklists, electronic order set modifications, an electronic test add-on tool and audit and feedback. The primary outcome was mean volume of blood collected per patient-day. Secondary outcomes included the number blood tubes used and red cell transfusions. Balancing measures included the timing and types of blood tests, ICU length of stay and mortality. Outcomes were evaluated using process control charts and segmented regression.

Results Patient demographics did not differ between time periods; total number of patients: 2096, median age: 61 years, 60% male. Mean phlebotomy volume±SD decreased from 41.1±4.0 to 34.1±4.7 mL/patient-day. Special cause variation was met at 13 weeks. Segmental regression demonstrated an immediate postintervention decrease of 6.6 mL/patient-day (95% CI 1.8 to 11.4

This was a retrospective observational cohort study between September 2014 and August 2015 at a tertiary care academic medical-surgical ICU. A prospective audit of phlebotomy practices in March 2018 was used to estimate blood waste during vascular access. Multivariable logistic regression was used to evaluate phlebotomy volume as a predictor of ICU nadir hemoglobin < 80 g/L, and red blood cell transfusion.

WHAT IS ALREADY KNOWN ON THIS TOPIC

⇒ Repetitive phlebotomy contributes to intensive care unit (ICU) acquired anaemia and red blood cell transfusion.

Results

WHAT THIS STUDY ADDS

⇒ Multimodal interventions focusing on ICU test ordering behaviour can result in a durable reduction in ICU phlebotomy and blood test tube consumption by reducing clinician identified unnecessary testing.

HOW THIS STUDY MIGHT AFFECT RESEARCH, PRACTICE OR POLICY

There were 428 index ICU admissions, median age 64.4 yr, 41% female. Forty-four patients (10%) with major bleeding events were excluded. Mean bedside waste per blood draw (144 draws) was: 3.9 mL from arterial lines, 5.5 mL central venous lines, and 6.3 mL from peripherally inserted central catheters. Mean phlebotomy volume per patient day was 48.1 ± 22.2 mL; 33.1 ± 15.0 mL received by the lab and 15.0 ± 8.1 mL discarded as bedside waste. Multivariable regression, including age, sex, admission hemoglobin, sequential organ failure assessment score, and ICU length of stay, showed total daily phlebotomy volume was predictive of hemoglobin <80 g/L (p = 0.002), red blood cell transfusion (p<0.001), and inpatient mortality (p = 0.002). For every 5 mL increase in average daily phlebotomy the odds ratio for nadir hemoglobin <80 g/L was 1.18 (95% CI 1.07–1.31) and for red blood cell transfusion was 1.17 (95% CI 1.07–1.28).

⇒ This study identifies change strategies that can be adapted and implemented in other care environments to reduce blood waste, conserve blood testing tubes and reduce blood collections. Future efforts are needed to translate these results to other care environments

The project began by trying to understand the source of the problem. Through staff interviews, diagramming exercises, and extensive literature review several interventions were developed for the project. Many change strategies involved working closely with Laboratory Medicine to restructure the lab test ordering system and interface to ensure clinicians were considering the amount of bloodwork they were ordering. Other change strategies involved developing educational and infographic material for staff in the MSICU to raise awareness of this issue. I developed the Pause the Draw campaign to tie all of our interventions together into a recognizable initiative for staff. In addition, I worked closely with the data department to collect and analyze different lab metrics to track the success of our interventions and provide valuable feedback information to staff each week on their progress.
