Advantages of Incremental Bridge Launching Techniques
Construction bridges can be challenging. The incremental launch method for construction of bridges has many advantages. Organizations could consider the following points when planning a bridge launch or construction project. One company which provides construction services is Bygging-Uddemann.
There are various challenges to constructing bridges even on straight or simple terrains. When it comes to valleys, areas with poor soil conditions and water bodies, constructing bridges can be even more difficult due to equipment limitations or other reasons such as limited or restricted access. However, construction engineering has always made use of innovative technology and processes in order to build sturdy, aesthetically appealing structures even when a place is topographically challenging. The incremental technique of constructing bridges is one such innovative solution to bridge construction that has been widely used for many years now (Mike LaViolette HNTB Corporation et al, “BRIDGE CONSTRUCTION PRACTICES USING INCREMENTAL LAUNCHING”, 2007).
Incremental launching of bridges involves highly mechanized assembly methods where the bridge superstructure consists of sections that are manufactured in the prefabrication area. Each new section is directly fixed to the preceding section. The structure is then moved forward by each incremental section. This process is made possible due to the compression and tension properties of the base material that the frame is made of as well as the design of the structures (CivilDigital.com 2016). For organizations that would like to consider this bridge launching method for any planned construction projects, the following are a few advantages of this technology that could help with the decision:
Speed: Constructing a bridge using the incremental launch method is a fast and efficient process. Most of the building and advancing of the bridge over pillars happens in fixed installments with a repetition in the design and process of fixed segments. These segments are then advanced ahead in small increments, making the process fast and easy.
Access: One major advantage of this method is that the majority of construction work can take place from the prefabrication areas. Issues of accessing difficult parts of the location such as deep valleys or steep slopes could thus be easily dealt with. For example, incremental launching reduces access required underneath bridges. These smaller but more concentrated areas of work for construction of the superstructure would also be easier to maintain.
Safety: There is increased worker and employer safety since all construction and assembly processes are done onsite of the prefabrication area. This safety also stems from work being performed at lower elevation levels and not actually around bridge pillars or half-constructed platforms.
Other Advantages: There are various other advantages of this method. Incremental construction methods require smaller bridge launching equipment. There would not be much need for equipment that is required for delivery of materials to constructed areas of the platforms as work takes place in prefabrication area. Another advantage is that the disturbance to surroundings would be minimal, especially to environmentally protected areas.
Constructors, especially bridge owners, could consider whether they should opt for innovative bridge assembly methods according to what suits their specific requirements, as well as what best suits the features of the site of construction. Based on professional and engineering insights as well as reviews of other successful and failed constructions, organizations could plan the construction project with the help of construction experts.
