The site and the Neretva river
The site, where the Old Bridge of Mostar was located, is in the most ancient core of the town, and on both banks of the river there are ancient stone buildings in the typical architecture style of the place, influenced by the Ottomans. The river Neretva is quite lower than the adjacent streets leading to the bridge, being the average river level at m.42 (a.s.l.), the average riverbed level at m.38 (a.s.l.) and the average street level at m.55 (a.s.l.). River banks, composed of natural conglomerate rocks, are quite steep: this happen mostly on the east side, where masonry stone walls of the buildings and rocks, (on which they are founded), make a sort of vertical barrier to the river flows.
The river Neretva runs from north to south and,
100-150 metres before the bridge site, the riverbed gets suddenly smaller and makes a turn
which leads the flows more towards the east bank.
The technical meetings
Until the and of August we had ten official
technical meetings. They are held mostly in Supervisors premises. The standard
On 12.07.2002 we started with the erection of the
scaffolding for the side walls. This scaffolding is necessary for the reparation works on
We started with scaffolding on west
downstream wall (M5c, M5b, M5a), the upstream wall on the same bank followed (M3b, M3a),
then we crossed the river and finished the left bank M4 upstream wall. Now we are making
the preparations to erect the scaffolding on the two remaining walls on the downstream
east side (M6 and M9).
Drillings for the foundation of the crane
After determining the best possible position for placing the main crane, investigations of the soil under the foundations was made.
So, four deep drills were made on
spots were the crane foundations were supposed to be established. The approximate depth of
the holes was 6 meters.
On four concrete blocks, the wooden deck will be installed as the base for the trails of the crane POTAIN GMRT 486 A, with range 50m, max weight 1.3 tons at the end of the boom.
Laboratory testing of the materials
As the preparations for bridge construction started, one of the first steps is to find and determine proper materials. They must fulfill many conditions: strenght, size, colour, chemical characterist, etc; if not the same - they must be as close as possible to the ones used on the Old Bridge.
At this moment tests of stones for masonry (breca, krecnjak, conglomerate), lime stone and sand are ongoing.
Traditional 436. Dives from the Old Bridge
On Sunday, 24.08.2002, the 436. traditional dives
from the Old Bridge were held. This Year 33 divers in legs first and 14 in
head first, took part in this competition. The winners are Ermin Zukanovic and
Haris Dzemat, both from Mostar. The Constructer of the Reconstruction of the Old Bridge
provided the platform for dives on its own expense.
