A) Reasons for Renewal of İstiklal Street Infrastructure
The deformation caused by the stretching of the tram rails on the street is broken or broken by the passing of the vehicles for the suppliers of the commercial shops in the street.
The historical vault (wastewater removal channel) passing under the avenue brought some restrictions to the works.
For this purpose, before the work on the renovation of the floor covering of İstiklal Street with a different design and material, the historical vault will be covered with precast concrete by a special construction method and the historical value will be preserved by the İSKİ and the ground will be stabilized.
In this way, it will be prevented that the tram rails will be stretched and that the floor covering and other infrastructure systems (natural gas, electricity, internet and telephone, fiberoptic lines, wastewater and rain water lines) will be rebuilt in such a way that they will not deteriorate again.
B) Beyoğlu Istiklal Street -French Consulate and Galatasaray High-Historic Vault
Stone wall on the sides, brick ceiling, width 120 cm. height 180 cm. Rainwater and wastewater of the region are removed by means of a horseshoe-shaped 563-meter-long vault from the Ottoman period.

A survey of the work was taken by the General Directorate of İSKİ, and in accordance with the decision of the Istanbul Regional Board for the Conservation of Cultural and Natural Heritage No. II, dated March 9, 2011 and numbered 4315, the vault will be covered with precast concrete from the inside and the original parts will be partially exhibited.
The interior of the vault will be covered with precast concrete by entering from the 5 shafts to be opened on İstiklal Street, thus strengthening the vault.
Studies about the historical vault:
Works will be carried out between 23.00 and 07.00 hours.
Daytime work will also be done when deemed necessary.
The work cabins are demountable and the clock will be collected at 07.00 and adapted to the pedestrian traffic on the manhole.
5 April 2012 (today) At the midnight of Galatasaray High School, Tonoz cleaning work will be started and the area will be ready for the project.
4-5 days after the opening of the shaft will be installed demontable cabinets.
For safety purposes, the mouse and its live output will be blocked by a fine-spaced wireframe at the start and end points of the stage within the gallery.
1 on each side of the chimney specified in the project; its dimensions are inside (2.50×3.00) m; so that the floor elevations are at the same level as the vault gallery floor level. Manholes will be built.
During the work on reinforced concrete manholes, the pavement material for the pedestrian path, at the upper elevation; Sliding or folding covers made of checkered sheet will be mounted. Precast elements will be mounted by transporting them in the gallery with a port-pallet.
To carry the precast elements into the gallery and perform the optimum work items on the vaulted side wall; 1.50 × 2.00 size; A gallery with the upper part in the form of an arch is opened (the inner surface and the wall of the gallery will be strengthened with a steel construction enclosure and even the gallery will be connected with the manhole wall). The passage on the vault wall (1.50 × 2.00m) will be opened without damaging the structure with the core drilling machine.
The precast elements that have been manufactured in accordance with the project and their details and brought to the construction site will be carefully placed in the manhole with the help of the crane and the assembly will be carried out with the movement within the gallery.
During the precast installation in the vault, the vault appearance can be observed by installing special precast elements with laminated glass windows of 40 x XUMX cm as required by the Board of Monuments.
Following the precast installation; The cement shall be injected with the grout-injection machine between the precast elements and the membrane covered in the vault.
