Water is essential to sustain life and the protection of water sources is an increasingly important issue. However, implementing water protection measures can be difficult due to economic factors, time constraints or political motives. Recently, the ecosystem services framework has been modified to aid in the implementation of water protection measures, which are called water system services. This thesis is focused on investigating how the concept of water system services (WSS), i.e. services provided by water sources to society, can be included when performing a risk assessment for the protection of water sources. Visualizing the WSS in an effective and informative way is a key step to show what services and the importance of the services that the water sources can provide. The water sources that are investigated in this report are Lake Mjörn and Sollebrunn-Gräfsnäs aquifer. To start the investigation, a thorough literature review on the subject of water protection and visualization was performed. A previously made list of WSS was used to identify existing services for the water sources. Identified hazards were then connected to the existing services. The identified WSS and the connection to the hazards were visualized, and if there were hazards that were also a service these were visualized as well. To exemplify, a risk assessment was then performed for one hazard at each water source. The identified WSS was given scores based on decided parameters and the specific threats of the hazards. The key result of the study is a strategy for how to incorporate WSS into risk assessment for potential or existing drinking water sources. The visualizations presented are examples of how the relation between WSS and hazards can be illustrated for different stakeholders and recipients. In conclusion, including WSS in the risk assessment provides a bigger picture than just looking at the service of drinking water and the developed method can be used in the process of creating a water protection area.

3D Strut-and-tie modelling interactive design using peridynamics: Development of a tool for generating strut-and-tie models using peridynamics combined with optimisation for an efficient reinforcement placement
(2022) Thorsager, Kalle; Udén, Mattias; Chalmers tekniska högskola / Institutionen för arkitektur och samhällsbyggnadsteknik (ACE); Ander, Mats; Örnborg, Johan; Olsson, Jens
The design of discontinuity regions in reinforced concrete structures is usually investigated in the ultimate limit state with a Strut-and-Tie Model (STM). By using STM the structure is designed by a lower bound approach according to the theory of plasticity. This makes the design conservative, assuming that the concrete structure can undergo sufficient plastic deformation. Therefore, it is good practice to construct the truss for the STM from the linear stress state in the structure. A new efficient GPU accelerated method for the particle-based method peridynamics is proposed to produce the principal stress field in these regions interactively. Voxels are utilised to discretise the input volume into particles. The use of voxels in the peridynamics workflow has proved useful in terms that each particle’s neighbour list is implied and data locality is assured. By implementing the peridynamics solver so that it utilises the GPU, the run-time of the simulation is drastically decreased on a personal computer. The boundary conditions are also treated with a new implicit method which reduces the influence of edge effects close to the boundary. An initial truss topology is then produced algorithmically by tracing curves in the principal stress field. Nodes are created at local maximum von Mises points along these curves and new curves are traced from these nodes. Nodes are also inserted at relevant intersection points between the traced curves. Based on these principles an initial truss topology can be created for most structures. A gradient-based optimisation is applied to the truss topology to get a truss with minimal reinforcement volume while still fulfilling the checks for the STM in a simplified manner. The gradient of displacement is used both with regards to the change of the initial node locations and element areas. The resulting truss and distribution of the reinforcement will be useful in an early design process but since the exact placement of the bars is not decided a more detailed analysis will be needed at a later stage. The application is useful in terms of understanding the structural behaviour of 3D structures and estimating the reinforcement volume and placement.
A (s)pace for rest: how architecture can support recovery and reduce stress for hospital staff
(2022) Barkfors, Ebba; Bergman, Jennie; Chalmers tekniska högskola / Institutionen för arkitektur och samhällsbyggnadsteknik (ACE); Caira, Cristiana; Miedema, Elke
Work-related stress is one of the most common causes of illness reported by workers. The Swedish Work Environment Authority’s forecasts show that stress-related illness is expected to increase in the future. The solution to the problem of work-related stress is complex and requires multidisciplinary measures. Recovery is a key factor for us to feel good and be able to perform. The institute of stress medicine in Gothenburg has conducted a study to assess how the pandemic has affected the work environment. One of the conclusions from the study is that it is vital to ensure that there is a possibility of recovery during working hours. The most vulnerable workers are those in the healthcare and health sectors. During times of high workload such as the pandemic, studies show that many healthcare workers perceive their work environment as deteriorating. In general, healthcare staff currently have no guaranteed specific space at their workplace to be able to have an effective recovery during working hours. The physical environment has a great impact on our ability to recover mentally. Studies show that access to greenery in the workplace has a positive effect on stress and that the right type of focus and degree of complexity in a space can also reduce stress. The purpose of the thesis has been to explore the need for and design of a facility for healthcare workers that can support recovery and prevent work related stress. The aim has been to create an architecture where the design can support mental recovery by working with senses and atmospheres. The methods include literature studies within restorative environments, biophilic design, salutogenic design and interviews with relevant informers such as healthcare workers and people working within the field of occupational health. The investigation resulted in a design proposal consisting of partly acupuncture interventions and mainly a building, with a restorative layout that supports healthcare workers mental health both in a preventive and rehabilitating manner. It is located within Sahlgrenska University Hospital in Gothenburg.
A beacon of hope

The hospital and the museum are not such distant cousins. The hospital attempts to heal the body; the museum attempts to heal the soul. - Josef P. Kleihues The museum projects (1989). Globally, the LGBTQ community lack spaces safe enough to collectively and publicly explore identity and build relationships. Historically, bars have often filled that gap, as they sometimes do today. In fact, it was at a bar that the LQBTQ liberation movement was started. But bars are problematic and non-inclusive in several ways, where age, alcohol consumption, appearance and ability can all define access to the community. With time, the Internet and applications have instead become the prevailing ways to connect. The internet is, however, Janus-faced: as a tool to explore one’s identity it can provide the best kind of support, or - it can strike with the most brutal hatred. Whichever the case, virtual meeting rooms or platforms are too often used as replacements for real-life socialising, yet they have not fully replicated or replaced the sense of community and belonging enabled by physical space. To challenge the status quo, this thesis explores the possibilities of an LGBTQ museum in Gothenburg, Sweden. Around the world, very few museums of the kind exist. It is a two-fold investigation looking into the prospective museum’s program and the visibility of the building: a program built around the needs and aspirations of the LGBTQ community; and, material research, focusing on how the glass block as a building material can be used to consciously manipulate light and manifest the museum’s importance. A museum is the pinnacle of cultural and historical recognition for a community. Groups that have been excluded by museums often feel a sense of invisible or erasure by society at large. The modern museum not only makes inclusion possible but has, as a model, gradually transformed over the years, transcending traditional program. They are now expected to be social spaces and active in community development. This investigation - a research-by-design project – uses the typology and location of the museum as a starting point. The free-standing museum building is situated in a historical urban context on the old ramparts; near the city moats. The openness of the facade is a conscious decision, making visible the stories of the LGBTQ community to visitors and passers-by alike. Transparency and light have been key factors and research drivers, as have the contrasts between conceal/reveal and night/day. The glass block as a building material rose to fame in the 1930s, the golden era of advertisement, due to its capability to illuminate entire buildings. The aim has been to create an intriguing, eye-catching and also inviting building, that appeals to people from within the community as well as to the public at large. Revealing during the day, alluring at night. A beacon of hope - Illuminating the night sky.

A case study of plastic pipe recycling within Civil Engineering
(2020) BILLING, TOBIAS; Chalmers tekniska högskola / Institutionen för arkitektur och samhällsbyggnadsteknik (ACE); Buser, Martine; Buser, Martine
The basis of this master’s thesis is to investigate how recycling of pipe scraps is currently being handled at NCC and also how the whole system for pipe scraps is currently set up. The aim of the study is to compare this system with the models of circular economy in order to investigate if they are compatible, and to analyse what further measures need to be taken so that the recycling of pipe scraps can be improved and further adhere to the principals of circular economy. In order to acquire information about how NCC is handling pipe scraps today, several interviews have been conducted. Workshops at two different construction sites have been carried out. Attending the workshops were craftsmen, supervisors and subcontractors. To gain further information about how the whole pipe scrap system is set up, interviews have been conducted with pipe manufacturers, and a waste management company. On a separate note, the author of this paper is working at NCC which could increases the risk for blind spots and biased analysis. The results of the workshops and interviews indicate that the current system for handling plastic pipes is not adhering to the principals of circular economy. The reason for this is: 1) Manufacturers cannot produce plastic pipes made from recycled pipe scraps in large enough scale due to material demands. 2) There are currently no profitable collection systems that can maintain the material value of plastic pipe scraps. 3) Rules and regulation fail to create incentives for recycling and circular business models. 4) It is not possible to deploy a green procurement strategy. NCC and the actors who are involved in the recycling process for plastic pipes could further adopt the principal of circular economy by adhering to activities such as: research on sustainable business models for collecting pipe scraps, research in material technology for plastic pipes, endorsement of collaboration between companies involved in the recycling chain and implementation of new rules and regulations.

The dynamic model of knowledge creation is based on the critical assumption that human knowledge is created and extended through social interaction between tacit and explicit knowledge. Knowledge is created by individuals and is then passed on to the organization through the knowledge spiral. This theory implies that organizations are incapable of creating knowledge on their own. However, many organizations attempt to collect tacit knowledge and transform it into codified information - usually in forms of documents, procedures, and manuals. Therefore, it is essential for organizations to have a well-developed knowledge transfer process to utilize the knowledge that exists within the organization long-term. In the context of the construction industry, there are many different disciplines interacting throughout the lifecycle of a project, making the industry knowledge intensive. Construction typically involves many processes and project participants, which is reflected in the highly fragmented nature of project implementation. A common method of knowledge transfer is to make knowledge explicit and store it in the form of computer programs and databases. Conversely, studies show that knowledge-based systems have difficulty transforming tacit knowledge into explicit knowledge. This study is based on the interest to investigate how a large construction company in Sweden manages knowledge transfer at an organizational level. Serneke, the company studied, currently invests in digitalization and a digital business operational system called VLS, which they believe will improve knowledge transfer in the organization. The study presents challenges with knowledge transfer in the construction industry, as well as challenges with the development of computer programs and platforms from the perspective of knowledge transfer. The results identify important elements in the process of improving knowledge transfer at Serneke. It is concluded that Serneke's investment in the development of VLS is an important step towards improving knowledge transfer within Serneke. VLS will facilitate knowledge transfer as it creates a common information structure across the organization. Furthermore, this study has identified that the SECI theory is applicable to many areas within the organization. Finally, it appears that the organization should work to promote factors that facilitate knowledge transfer.

A circular home; investigating tools for resilient architecture

Our society has urgent challenges with water supply, food production and electricity availability, due to environmental issues and wars. Architects can contribute more conscious to all these fields by letting our architectural tools be based on nature’s resources and its conditions. By considering one of the main tasks of architecture, keeping us warm, already in the sketch phase the buildings get less dependent on mechanical systems, and by seeing water and food more as circular systems our architecture becomes more resilient. To get background knowledge, literature and built references was studied. The knowledge was then translated to design strategies, to act as a toolbox in the design phase. As a complement to the design strategies, references have been studied and a building program was created, that also inspires and imposes demands on the building. The result is a prototype house for one family, which in this case was tested on a plot outside Gothenburg. A detailed sun study was carried out for the site as it impacts several design principles. In the proposal, rooms are placed according to the time of day they are used and temperature requirements for each room in relation to the sun movement. The common spaces are allowed to expand and shrink while need and season changes, further the user can experience different zones within the home, ranging from colder rooms to different greenhouse zones, thus blurring the boundaries between outside and inside. The house is designed with solid materials such as wood and brick, and through its thoughtful placement, they contribute to the heating of the house as well as the architectural expression. The tricky part is to do precalculation of how it impacts the indoor climate when trusting nature. If there were more time, an investigation of putting several units together would have been interesting. The tools can be implemented on a larger scale than a singlefamily house, thus contribute to a more sustainable construction sector with resilient architecture

A combination of a road restraint system and a noise reducing device
(2017) Burgos, Claudia; Wåssén, Linnéa; Chalmers tekniska högskola / Institutionen för arkitektur och samhällsbyggnadsteknik; Chalmers University of Technology / Department of Architecture and Civil Engineering
Based on measurements performed on a low-height noise barrier, an investigation was commenced on where such product could be implemented with respect to both noise reduction and to road restraint requirements, including traffic safety. By using three noise prediction tools, SoundPLAN (version 7.4), a Boundary Element Method (BEM) and an analytic solution, the screen insertion losses could be estimated and compared. The screen heights that were studied were 1.2m and 1.4m. The noise reducing effects of these screens were investigated in two real cases that were given by Malmö Stad and in a theoretical case. Standards for both a road restraint system and a noise reducing devise have been studied and summarised to facilitate the development of the combined system. The insertion losses for the two heights were 10 dB(A) and 11 dB(A) respectively when calculating for the theoretical situation. For the real case scenarios, the insertion losses were deteriorated to around 3 dB(A), concluded to be due to reflections in surrounding facades. The deviations in insertion loss between the different calculation methods was at most 2 dB but the results for the increased barrier height showed that a higher insertion loss could be achieved. The use of the BEM results, which were pre-calculated and provided to the project, showed that an absorbing screen should be considered when it comes to a lowheight noise barrier, since an even higher reduction could be achieved. A low-height noise barrier should be considered and further investigated since it actually reduces the levels of community noise and has good potential to protect pedestrians from collisions within an urban environment.
