The Holy Mosque in Mecca is the most important and the biggest Islam mosque in the world. An additional floor has been built in the interior around the main sanctuary of the Kaaba. The project's name is ’Mataf Extension‘.
It is a reinforced concrete construction with a floor span of 15 m and dimensions of the main beams are h / w = 2.2 m / 3.6 m with a span of 23 m.
Supporting Structure Made of Steel Trusses
To allow the use of the surfaces below the new floor during construction, wide‑span steel structure supporting girders instead of conventional scaffolding were used to support the shell structure.
The beams were designed as spatial trusses and were designed for the weight of the fresh concrete of the main and secondary floor beams. Dimensions of the steel beams are h / w = 3.36 m / 2.45 m with a total length of up to 56 m. They were created and designed by the engineering office Mauss using RFEM.
A substantial amount of work was due to the changes during the approval and assembly phases which were carried out under enormous time pressure.
