Izdelava BIM-modela zgrajenega večetažnega objekta na podlagi oblaka točk s programsko opremo Revit : diplomska naloga

Zupančič, Blaž (avtor), Klinc, Robert (mentor), Kregar, Klemen (komentor)

V okviru diplomske naloge smo preizkušali proces izdelave modela že zgrajenega objekta. Modelirali smo stavbo Fakultete za gradbeništvo in geodezijo na Jamovi cesti 2 v Ljubljani z namenom, da preizkusimo in ovrednotimo proces izdelave modela že zgrajenega objekta na praktičnem primeru. Uporabnost samega modela je odvisna od njegove natančnosti in od količine elementov, ki jih upoštevamo pri modeliranju. Ustvarjanje modela je temeljilo na oblaku točk, ki je bil zajet z laserskim skeniranjem s 126 stojišč. V sklopu modeliranja v programu Revit smo se osredotočili predvsem na modeliranje nosilne konstrukcije in nekaterih drugih nenosilnih delov. Odločili smo se za ročno modeliranje elementov, saj nam to omogoča večji nadzor nad natančnostjo postavljenih elementov. Druga možnost je modeliranje s samodejnimi metodami, ki obljubljajo samodejno modeliranje elementov, kot so stene in plošče. Za to metodo se nismo odločili, ker ni ponujala bistvenih prednosti pred ročnim modeliranjem. Modeliranje je potekalo na podlagi prerezov skozi oblak točk in dodatnih izmer na terenu. Bistveno težavo je predstavljalo dejstvo, da v oblaku točk ni bila zajeta celotna notranjost objekta, kar je pomenilo, da smo nekatere elemente morali zanemariti. BIM-model celotnega objekta je nastajal tudi s pomočjo sodelovanja preko standarda IFC, ki v teoriji omogoča uvažanje in izvažanje modelov med različnimi programi. V nalogi smo opisali glavne težave, ki jih srečamo v procesu izdelave modela že zgrajenega objekta.

Izvleček

As part of this bachelor's thesis, we analysed the process of creating an as-built model of an existing building. We modelled the Faculty of Civil and Geodetic Engineering’s main building on Jamova cesta 2 in Ljubljana with the aim of evaluating the process of creating an as-built model on a practical example. The usefulness of the model depends on its accuracy and the number of elements considered during modelling. The creation of the model was based on a point cloud generated from 126 different scans. In the process of modelling in Revit, we focused primarily on modelling the load-bearing structure and some other non-load-bearing parts. We opted for manual modelling of elements, as it allows for greater control over the accuracy of the placed elements. Another option was modelling using automatic methods, which promise automatic modelling of elements. However, we did not choose this method because it did not offer significant advantages over manual modelling. The modelling was based on sections through the point cloud and additional measurements taken on-site. A significant challenge was the fact that the entire interior of the building was not captured in the point cloud, which meant that some elements had to be omitted. The BIM-model of the entire building was also created with the help of collaboration through the IFC standard, which theoretically enables the importing and exporting of models between different software. We also addressed the main challenges encountered in the modelling process and captured some of the key steps required for creating an as-built model.
