Bridge Engineering Optimization Opportunities Through Integrated Solutions: Design – Constructive Method
The demand for productivity and cost optimization is a common requirement of bridge construction process nowadays. Focusing on span-by-span concrete bridges, different solutions have proved to be efficient. The choice for the most adequate solution is not linear and depends on several factors of quite different nature, such as bridge geometry (curvature, transversal slope, longitudinal slope), deck section (weight, shape), span length and bridge total length, environmental conditions, site logistics, local construction and design traditions and constructor experience and preferences. Independently of the chosen solution, a fundamental factor for achieving a cost and time-efficient construction process is a timely cooperation between the bridge designer and the construction process developer, making key adaptations in bridge design in order to make it easier for construction. In this specific case, details do matter and a judicious choice may have a significant impact in construction times. In this paper, different span-by-span concrete bridge deck construction processes are presented, ranging from segmental pre-cast to cast in situ solutions. The different solutions have a common denominator – the demand for productivity. The presentation is based on real examples. Throughout the text, a reference is made to Organic Prestressing System (OPS), an actively controlled prestressing system that increases structural efficiency. In its recent applications on bridge construction equipment, OPS confirmed a positive impact in productivity. A particular focus is given to the M1-90-S, a span record holder movable scaffolding system, mainly manufactured in Turkey and currently in operation in Ankara-Sivas high speed railway.
