20.500.12556/RUL-183090 Uporaba terestričnega 3D laserskega skeniranja za potrebe izdelave projekta izvedenih del predora Legi Kamen v BIM okolju magistrsko delo Application of terrestrial 3D laser scanning for developing as-built model of Legi Kamen tunnel in BIM environment master's thesis V magistrski nalogi je predstavljena uporaba terestričnega 3D laserskega skeniranja za analizo obstoječega stanja novozgrajenega objekta kolesarskega predora Legi kamen in pripravo njegovega informacijskega modela v skladu s tehnologijo ang. ˝Building Information Modeling˝ v nadaljevanju BIM. Predor, dolg 105 m in širok približno 4 m, je služil kot primer infrastrukturnega objekta, kjer je mogoče z uporabo naprednih metod zajema in obdelave prostorskih podatkov preveriti skladnost izvedenega stanja s projektno dokumentacijo. Namen naloge je bil oceniti zanesljivost in natančnost podatkov, pridobljenih z laserskim skenerjem Leica RTC360, ter prikazati njihovo uporabnost pri ustvarjanju modelov izvedenega stanja. V okviru naloge je bil izveden zajem oblaka točk z visoko gostoto, geo-referenciranje na geodetsko mrežo in nadaljnja obdelava podatkov v programskih okoljih Cyclone Register 360 PLUS in Leica 3DR. Posebna pozornost je bila namenjena postopkom prostorske analize, kot so sekcijska analiza in primerjava z načrtovanim svetlim profilom iz projektne dokumentacije PZI (Projekt za izvedbo). Rezultati so pokazali, da odstopanja med obstoječim in projektiranim stanjem večinoma ne presegajo ±3 cm. To potrjuje, da je notranja obloga predora izvedena ustrezno ter v skladu z gradbenimi tolerancami, opredeljenimi v projektni dokumentaciji (IRGO Consulting d.o.o., 2020). Obdelani podatki so bili nato uporabljeni kot osnova za nadgradnjo modela BIM za potrebe PID (Projekt izvedenih del), angleško ˝as-built˝. Iz oblaka točk in generiranega 3D mrežnega modela so bile oblikovane natančne geometrije, ki omogočajo vključevanje predora v informacijski BIM model objekta. Takšen pristop zagotavlja boljšo sledljivost izvedenih del, omogoča učinkovitejše načrtovanje vzdrževanja in nadzor kakovosti, hkrati pa odpira možnosti za integracijo v širši sistem upravljanja infrastrukture. Rezultati naloge potrjujejo, da je kombinacija terestričnega laserskega skeniranja in metodologije BIM primerna in učinkovita metoda za dokumentiranje izvedenega stanja infrastrukturnih objektov, kot so predori. S tem se izboljšata tako kakovost kot zanesljivost podatkov, kar predstavlja pomembno dodano vrednost pri izdelavi PID dokumentacije. This master’s thesis presents the application of terrestrial 3D laser scanning for the analysis of the as-built condition of the newly constructed Legi Kamen cycling tunnel and for the development of its information model in accordance with Building Information Modeling (BIM) methodology. The tunnel, with a length of 105 m and an approximate width of 4 m, served as a case study of an infrastructure object where advanced spatial data acquisition and processing methods can be used to verify the compliance of the constructed state with the design documentation. The aim of the thesis was to assess the reliability and accuracy of data acquired using the Leica RTC360 laser scanner and to demonstrate its applicability in generating as-built models. As part of the study, a high-density point cloud was acquired, georeferenced to a geodetic network, and further processed using the software environments Cyclone Register 360 PLUS and Leica 3DR. Special attention was given to spatial analysis procedures, such as cross-sectional analysis and comparison with the designed clearance profile defined in the PZI (Detailed Design) documentation. The results showed that deviations between the as-built and designed states generally do not exceed ±3 cm. This confirms that the tunnel lining was constructed appropriately and in accordance with the construction tolerances specified in the design documentation (IRGO Consulting d.o.o., 2020). The processed data were subsequently used as a basis for upgrading the BIM model for the purposes of the PID (As-Built Design Documentation). Accurate geometries derived from the point cloud and the generated 3D mesh model enabled the integration of the tunnel into the BIM-based information model. Such an approach ensures improved traceability of the executed works, facilitates more efficient maintenance planning and quality control, and opens possibilities for integration into broader infrastructure management systems. The results of the thesis confirm that the combination of terrestrial laser scanning and BIM methodology represents a suitable and effective approach for documenting the as-built condition of infrastructure objects such as tunnels. This approach enhances both the quality and reliability of the data, providing significant added value in the preparation of as-built (PID) documentation.
