 Pipiral Viaduct General description: Project: Pipiral viaduct and accesses, open roads and six bridges. Object: Study, design and construction of the viaduct and roads. Work commisioned from Ingetec: Revision of the design and supervision during construction. Contractor: Conciviles S.A. Supervsion: Ingetec S.A. - C.C.C. S.A. Joint Venture Technical characteristics: Viaduct alignment: Curved, with a radius of curvature of 452 m Length: The viaduct is a seven span, 545 m long structure composed of: two 22.5 m spans, two 62.5 m spans and three 125 m spans. Foundation: composed of three Ø 1.80 m caissons on each abutment, two supports composed of four Ø 2.50 m caissons and the remaining four supports composed of four Ø 3.70 m caissons. Infrastructure: Composed of two abutments and six piles varying between 15 m and 82 m in height. Superstructure: Composed of two pre-stressed concrete voussoirs, in successive cantilevers. The height of the voussoirs varies between 7.40 m and 2.8 m and a 12.90 m wide board distributed in a 10.90 m wide roadway and two 1.0 m wide sidewalks with a curved alignment. Surface roadways: 5.5 km. of roads and 6 bridges of variable length, from 30 m to 156 m. Characteristics of the roadway: Clearance: 9.40 m Width: 7.30 m Subbase: Granular of variable width. Base: Granular 0.20 m Pavement slab: 0.07 m asphalt concrete base – 0.05 thick asphalt concrete 0.05 m Berms: 2 asphalt concrete 1.05 m. Characteristics of the seven bridges: Pipiral pedestrial crossway: Length: 35 m, steel structure - spans: 1 (1 m). Overpass: K89+156: Length: 40 m, I-beam type - slab, No. of spans: 1 (40 m) and 8 Caissons (Ø1.5 m). Bridge at K 90+400: Length: 30 m, I - beam type - slab - spans: 1 (30 m) and 6 caissons (Ø1.2 m). Bridge at K 90+730: Length: 71 m, I-beam type - slab, No. of spans: 2 (30-40 m), 4 caissons (Ø2.0 m) and 1 caisson (Ø3.5 m). Bridge at K 90+940: Length: 139 m, I-beam type – suspended sections on piles - slab, spans: 3 (46-57-36 m), 4 caissons (Ø2.0 m) and 2 caissons (Ø3.5 m). Servitá
