Project
Type: Two parallel viaduct segments with a total length of 821 m (2693 ft.)
Typical Span: 45 m (147 ft.)
Deck width: 13,1 m (42 ft.)
Typical Cross Section: PI (π)
Equipment features
Model: MSS M45-S
Construction Type: In situ (In Place)
Type: Overhead MSS
OPS System: Integrated
Performance: 10-day cycles
Challenges
• Increase in travelling weight
• Very demanding formwork project due to the proximity of the decks and the radius of curvature on plan (low and variable)
• Allowing the client the 4th reuse of their own equipment
Solutions
• Calculations carried out in order to increase the travelling weight and keep the modification costs as low as possible in accordingly to the client's expectations
• Work done together with the formwork supplier in order to enable launching
Results
• Construction Period: 48 weeks
• High construction quality and deformation control
• Highly optimized deck construction
• High safety levels during construction

Project
Type: One viaduct, two parallel decks, length of 253,5m (831 ft.) + 223,9m (734 ft.)
Typical Span: 41.5 m (136 ft.)
Deck width: 13 m (42 ft)
Typical Cross Section: PI (π)
Equipment features
Model: MSS M45-S
Construction Type: In Place
Type: Overhead MSS
OPS System: Integrated
Performance: 14-day cycles
Challenges
• Construction of two parallel bridge decks identical to the ones made by the Movable Scaffolding System M45-S in its first project (Sokolov-Tisova).
Solutions
• Due to the similarity of the bridge decks, the natural choice was to use the same constructive method by refurbishing the M45-S.
• A safe choice proven in the past, economic and with a guaranteed deadline
Results
• Construction period: 34+34 weeks
• Fast construction
• High construction quality and deformation control
• High safety levels during construction
• The transversal movement of the machine for the construction of the second deck was an easy operation due to its reduced weight

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.
