The Nat ional Museum of Romanian H istor y is located in the histor ic bui ld ing a lso k nown as “ The Post Palace”. Designed by the architec t Alexandru Savulescu in neoclass ical s t y le with German inf luences, the edi f ice was bui l t at the end of the 19th centur y. The Post Palace becomes headquar ters of the Nat ional Museum of Romanian H istor y in 1972 and is nowadays a h istor ic monument. The struc ture of the bui lding was ser iously damaged by the 1940 and 1977 ear thquakes and is current ly undergoing a rehabi l i tat ion process. Therefore, i t was decided that a detai led documentat ion of the bui lding’s current state was needed and the sur vey was carr ied out us ing the 3D laser scanning method.

Advantages of the sur vey obtained through this innovative measurement technique, suppor t ing the rehabi l i tat ion projec t of the National Museum of Romanian H istor y are:

eBim based on the 2D sur vey (CAD to BIM)

These products are obtained based on the 3D laser scanning and are compatible to CAD software, often exported as*rvt, *fbx, *xml, *dwg, *dxf, *pdf files etc.

What is BIM | eBIM ?

Building I nformation M odel l ing (BIM) i s the process of bui ld ing a 3D model which contains parametr ic information about each e lement of a construc t ion, inc luding t ime and cost data . The model can be used to make decis ions dur ing the whole l i fe c ycle of a bui ld ing, f rom the design stage to maintenance, preser vat ion and rehabi l i tat ion works. Exist ing Bui lding I nformation (eBIM) provides a detai led and accurate 3D model of the current stage of a construc t ion made by process ing the point c loud obtained f rom 3D laser scanning.

Detai l level included in the 3D eBIM model :

- Vis ible struc tural e lements (columns, beams, s labs) ;- Ex ter ior e lements : ex ter ior wal ls , roof ;- Par t i t ion e lements : inter ior wal ls ;- Sta i rs , windows, doors ;- Sanitar y f i t t ings ;- Decorat ive architec tural e lements.

eBIM models can be generated in BIM software such as Autodesk Revit, Graphisoft ArchiCAD, RhinoBIM etc.
