A large component of the State of Utah's transportation network involves the use of MSE walls, which have proven useful in infrastructure for their reduced costs and footprint compared to other alternatives. As effective as MSE walls have been in responding to demands in transportation, they also have inherent challenges. For the majority of MSE walls the structure is limited in observation as structural components are buried as part of the soils mass. This inability to observe at can lead to the development of complex failure mechanisms, which can be difficult to assess and anticipate. As society becomes increasingly reliant on the transportation networks for goods, services, and security, properly understanding the potential failure mechanisms of MSE walls also increases in importance. This thesis discusses the development of an inspection procedure, data collection, geotechnical asset management database, and an evaluation of gathered information to be used in a reliability analysis of MSE walls for the State of Utah. The findings suggest areas of improvement in the design, specifications, maintenance, and further investigation of MSE walls.

The diploma thesis deals with inspection and construction technical survey of the reinforced concrete bridge structure and final evaluation of the condition of the selected reinforced concrete bridge object. This bridge structure is located on the road 4794 and overcomes the Olešná stream in the town of Paskov.

This diploma thesis focuses on diagnostics of bridge structures. First part of this diploma thesis will focus on theoretical knowledge about bridge structures and common diagnostic techniques suited for examining material priperties of samples taken from structure. Second part of this thesis will focus on practical use of experiments used in diagnostic branch. I will be doing visual observation of concrete structure followed by experiments on core samples. End of thesis will be evaluating structure from global perspective and will deliver specific sugestions for renovation.

Diploma thesis The complex diagnostics of bricked bridge construction is in the theoretical part focused on the summary of regulations of road and railway bridges. In the practical part was conducted the inspection and diagnostic survey of the railway viaduct on Křenová, near the main train station Brno.

The wastewater- and sewage distribution network is a critical aspect for maintaining a socialandenvironmental well-being. However, in the latest time, many failures (such as leakages) haveoccurred due to poor conditions in the wastewater-infrastructure, causing several consequencessuch as damage to the environment or pose health hazards to the public. This study is dividedinto three parts. Part one compares five different sewage inspection technologies: Closed-CircuitTelevision (CCTV), Zoom Cameras, Digital Scanning, SONAR and Electro Scanning with thepurpose of identifying a new system that Stockholm Vatten & Avfall (SVOA) should considerimplementing. Part two goes through the inspection procedure that SVOA applies, andrecommendations are concluded as to how the process can be optimized. Part three coversessential aspects that should be taken into account before investing in a new technology. Theresearch methodology involves collecting data from literature, internal reports from SVOA, andconducting interviews with supervisors and field workers. The main finding is that SVOA shouldcontinue with the current approach that the utility is using because the current data found in thecurrent literature is too insufficient and not too strong which makes it not convincing to investinto a new technology. On the other hand, the collected data about the technologies can beconsidered whenever the approach is moving towards a proactive approach.

Byggbranschen genomgår en digitalisering där drönartekniken ingår som en del av moderniseringen. Företag inom branschen strävar efter att tids- och kostnadseffektivisera sin byggprocess samtidigt som arbetsmiljön ska förbättras. Drönare används av allt fler byggföretag och syftet med den här rapporten är att jämföra hur implementering av drönare påverkar arbetsmiljö, kostnad och tidsåtgång vid utvändig besiktning och inspektion av byggnader samt volymberäkning. För att samla in relevant information har undersökningen bestått av litteraturstudier, intervjuer, frågeformulär samt fallstudier där drönare som verktyg har testats i praktiken. Resultatet av undersökningen har visat på fördelar med att implementera drönare som arbetsverktyg sett till arbetsmiljö, ekonomi, och tid. Jämfört med traditionella arbetsmetoder visar resultaten på att drönaren är ett billigare och smidigare verktyg att använda, dessutom förbättras arbetsmiljön då drönaren kan styras från marknivå. Baserat på rapportens resultat har slutsatsen varit att vinningar kan göras genom att implementera drönare hos byggföretag. Rekommendationen är således att inköp av drönare ska ses som en god investering för byggföretag. / The construction industry is undergoing a digitalization, where drone technology is part of the modernization of working methods. Drones are used by an increasing number of companies. Construction companies aim to make cost and time effective solutions while improving the working environment. The purpose of this report is to compare how implementation of drone technology affects economy, time and work environment during external inspection of buildings and volume calculations. In order to collect relevant information, the survey consisted of literature studies, interviews, questionnaires and case studies in which a drone as a tool has been tested in practice. The results of the survey have demonstrated the benefits of implementing drones as a work tool in terms of economy, time and work environment. Compared to traditional working methods, the results show that the drone is a cheaper and more flexible tool to use, as well as improving the working environment since the drone can be operated from ground level. Based on the results of the report, the conclusion has been that profits can be made by implementing drones at construction companies. The recommendation is that the purchase of drones should be regarded as a good investment for construction companies.
