This essay examines the concept of meaning in Sein und Zeit. By identifying a paradox in the question constituting the outset of Heidegger’s ontology, i.e. the question of the meaning of Being, the need of a clarification of the concept of meaning unfolds. According to Heidegger, namely, we have been asking the question of Being without even knowing what we mean; we have forgotten to ask the question of the meaning of Being. At the same time, since the actual question of Being necessarily is a question of the meaning of Being, i.e. since we, as human beings and as the sole origin of the question of Being, necessarily mean something with the questions we ask, we have been asking exactly the question we have forgotten to ask. What then, I ask, is this element, that we have been asking for but forgotten to address? What is meaning? Asking this question on the basis of Sein und Zeit, I argue, is necessarily to explore the Being of meaning, since meaning is something found in the constitution of Dasein, the human being, and since the explication of Dasein evolving in Sein und Zeit concerns exactly its Being. After clarifying this question, the study proceeds in three chapters, the first concerning the basic structure of Dasein, the second the understanding, as the knowing of this structure, and the third the explication, in which we finally find the constitutive elements of meaning, i.e. it’s Being. In dialogue with secondary sources, I then aim to discuss the implication of this Being, epistemic as well as political and ethical. Subsequently, I ask what this Being implies for the paradox initially noted.

Parkeringsanläggningar utsätts ständigt av belastningar från körande fordon och kloridangrepp under vinterperioden. Påföljden av det blir kostsamma skador på betongkonstruktionen, främst vid uppkomna sprickor. Kloridinträngning medför att armeringsjärnen korroderar och försvagar underliggande betongkonstruktionen. Ersättning av de korroderade armeringsjärnen samt betonglagningar är kostsamt för Stockholm Parkering. Lösningen är att förbehandla den oskyddade betongen och applicera en ytbeläggning ovanför. De vanligaste som finns i Sverige är cementbaserade, bitumenbaserade och härdplastbaserade ytbeläggningar. Det finns inga direktiv för val när det gäller ytbeläggningar. Eftersom alla ytbeläggningar har olika egenskaper är det för- och nackdelar som beställaren ska värdera beroende på parkeringshusets förutsättningar som utformningen, trafikbelastningen och om det är grundplattan eller mellanbjälklaget som ytbeläggningen appliceras på. Förutom materialet är utförandet också viktigt. En väl utförd förbehandling av betongunderlaget och noggrann utläggning av ytbeläggningen minskar risken för uppkomst av skador i framtiden och därmed reparationskostnaderna. Syftet med examensarbetet är att undersöka olika ytbeläggningar som har varit i drift 5 till 10 år för att sedan identifiera och kartlägga skador som har uppkommit på dem. I denna rapport har fem parkeringsanläggningar valts ut som fallstudier för att undersöka de vanligaste ytbeläggningarna som används idag i Stockholm Parkerings parkeringsanläggningar. Utifrån litteraturstudier, intervjuer med olika parter i respektive projekt, observationer som utfördes under studiebesöken och jämförelse mellan fallstudier dras slutsatser för att hitta den hållbaraste ytbeläggningen. Slutligen skapas en lathund för att förenkla valet av ytbeläggningar för parkeringsanläggningar med olika förutsättningar. / Parking facilities are constantly exposed to traffic loads from driving vehicles and chloride attacks during the winter period. The consequence of this is costly damage to the concrete structure, especially in the event of cracks. Chloride penetration causes the reinforcement bars to corrode and weaken the underlying concrete structure. Replacement of the corroded reinforcement bars and concrete repairs are costly for Stockholm Parking. The solution is to pretreat the unprotected concrete and apply a coating above it. The most common coatings found in Sweden are cement-based, bitumen-based and thermoset-based coatings. There is no clear choice when it comes to coatings since they all have different properties. The advantages and disadvantages of different coatings that the customer must value depend on such conditions of the parking garage as the shaping, the traffic load and whether it is the base plate or the intermediate floor. Besides the material, the execution is also important. A well done pretreatment of the concrete substrate and meticulous laying of the coating reduces the possibility of the occurrence of damage in the future and thereby the repair costs. The purpose of the thesis project was investigation of various coatings systems that have been in operation for 5 to 10 years and identification and mapping damages that occur to them. In this report, five parking facilities have been selected as case studies to investigate the most common coatings used today in Stockholm Parkering parking facilities. Based on literature studies, interviews with various parties in each project, observations made on study visits and comparison between case studies conclusions were drawn about the most sustainable surface coating systems. Finally, a guidance is created to simplify the choice of coating systems for parking facilities with different conditions.
