Client
Project
Type: Viaduct, total length 957m (3139 ft.) (construction with MSS: 702m - 2303 ft.)
Typical Span: 69 m (226 ft.)
Deck width: 25,66 m (84 ft.)
Typical Cross Section: Box (in two stages)
Equipment features
Model: MSS M70-S
Construction Type: In Place
Type: Overhead MSS
OPS System: Integrated
Performance: 20-day cycles (2 stages)
Challenges
• Finding a solution that would eliminate temporary structures and build the span that the designer intended (approximately 70m - 229 ft.)
Solutions
• Overhead Movable Scaffolding System M70-S (capacity for spans up to 70m - 229 ft.), previously used in Valencia
• On the basis of the study carried out with BERD, the bridge Designer opted for a 69m (226 ft.) typical span
Results
• Construction period: 55 weeks
• Construction faster than predicted in the initial project
• Optimisation – no need for construction and demolition of provisional structures
• Increased industrialization and easier operationally vis-à-vis the alternatives
• Higher construction quality due to the reduction and control of deflections
• OPS System allowed the cast of the box in two phases, without any danger of cracking
• Final reduction on the cost construction of the optimised viaduct compared to the initial project.
