PROJECT:  Design of new national road bridges Hania - Krokees - Monemvasia

CLIENT: Hatzistergiou G. and colleagues Office.
ASSOCIATED OFFICES:

BRIEF DESCRIPTION:
 
Detailed and final design of bridges for the new national road, in cooperation with the office of G. Hatzistergiou and colleagues. The services provided include complete design of projects in the preliminary and final design with hydraulic design (where there was a requirement) and design of scaffolds (in those studied by the stage of final design).
 
Detailed designs
  • Overpass intersection bridge at junction with national road Highway Sparta - Gythion at Ch 17+297. 3 span portal frame L = 53.45m (14.31 +24.84 +14.31), deck width 7.5m, girder d=1.1m, curved and transitional section in plan R = 142m. Prestressed  concrete, shallow foundation.
  • Stream, at Ch 0+675. One, simple supported, span length 31m, width 14.5m, girder d=1.30m in curve R = 250m. Prestressed concrete on piles (bored piles D100).
  • Gorge at Ch 1+362. 3 span portal frame L= 76m (20+36+20), deck width 14m, girders d=1.50m in piers with clear height of 13.7m. Prestressed concrete, shallow foundation.
  • Stream, at Ch 2+155.59. Closed box with net opening 6.00m, skew angle 760, length 20.5m. Reinforced concrete, shallow foundation.
  • Stream, at Ch 5+257.59. Closed box with net opening 6.00m, skew angle 800, length 30.5m. Reinforced concrete, shallow foundation.
  • Stream, at Ch 6+556.48. Closed box with net opening 6.00m, skew angle 370, length 48.7m. Reinforced concrete, shallow foundation.
  • Stream at junction KO3. Closed box with net opening 8.00m, skew angle from 900 to 690, width from 13.3m to 16.70m. Reinforced concrete, shallow foundation.
  • Stream at Ch 27+609.5 Boxed frame, clear opening 14.0m, with a clear height of 10.9m, deck width 12.0m, voided slab d=1.2m. Reinforced concrete, shallow foundation.
  • Stream at Ch 29+179.39. 3 span portal frame L = 53.7m (14.35 +25.00 +14.35), deck width 16.00m, girders d=1.10m. Prestressed concrete, shallow foundation.
Final designs
  • Stream at Ch 30+769.0. 3 span portal frame L = 52.6m (14.05 +24.50 +14.05), deck width 12.00m, girders d=1.10m. Prestressed concrete on piles (bored piles D100).
  • Stream at Ch 32+260.60. Closed box with net opening 8.00m, skew angle 530, deck width 12.0m. Reinforced concrete, shallow foundation.
  • Gorge at Ch 33+309. 2 span portal frame L = 63.4m (2x31.7), deck width 16.5m, site construction in phases, box deck d = 2.00 m, curved in plan with R = 125m, pier net height 16m. Prestressed concrete on piles (bored piles D100)
The project has been completed and in operation.
