- arranging a second hanger part 8 through the opening 305 of the structure 300;

- supporting the second hanger part 8 with the third supporting arrangement 10 on the structure 300; and

- supporting the support beam 2 with the fourth support arrangement 9 on the second hanger part 8.

In one preferred embodiment of the present invention, forming an opening 305 of the structure 300 from the upper surface of the structure 304 to the lower of the structure 303 being started from the upper surface of the structure 304.

In one embodiment of the present invention, the method further comprises removing the first hanger part 3 and the first supporting arrangement

4.

In one embodiment of the present invention, the method further comprises a step of removing a portion of the first edge 302 of the structure 300 . In one embodiment of the present invention, the method further comprises a step of replacing a removed portion of the first edge 302 of the structure 300 with a new material.
