The beam bridge is one of the popular types. After 18 days remove sheet centring. If there are no inerodable banks, over gorging, guide banks in dry locations also must be provided.During floods, the approaches must be secure from flood attacks or any major spills. Their need is studied based on the socio-economic viabilities.An assessment of the traffic type and its quantum is necessary to decide the following factors:The data collection for this must be done carefully so that a proper idea on how the traffic pattern, the growth strategies such as agricultural, industrial as well commercial developments are influenced.

The initial plans are prepared regarding the project, including the characteristics of the desired bridge, the site details, and the requirement of resources.

Based on the complexity of the barrier across which the bridge must be constructed, the detailing of the project planning increases, because more investigation must be carried out.

Investigations conducted after bridge failures have revealed that the real forces on bridges that collapsed were significantly less compared to the loads for which the bridge was designed. If there is bend in the downstream, it must be avoided. Dynamic loads are particularly of prime significance. This facilitates the feasibility of linking the cities and towns, which gain more importance in the overall growth of a nation. The main types of the bridges are beam, arch, truss, cantilever, and suspension. Two cables out of twenty-two are made of this material.The steel is available with higher capabilities, like high strength varying from 60MPa to 100MPa, that have remarkable ductility and corrosion resistance. A bridge is designed to endure the normal vehicle loads, and other forces created due to winds and earthquakes. Location study. On projects where the survey will tie-in to adjacent grading projects, the Project Supervisor shall contact the Grading Project Supervisor and check the location lines and bench marks. This arises in the situation of choice of location or the facility, or in prioritizing the needs for the welfare of the economy.The social dimension has a direct close connection with the scientific and the technological dimension.There have been many technological developments over decades in the field of new structures, methods of construction and materials, as an alternative for rare ones and in bringing new machinery that works over human workers.This technology has helped in bringing and refining alternatives in the bridge construction.

It is not only required for the bridges to satisfy the need of mobility and the future demands but also must satisfy the problems related to noise, pollution, during and after construction.As the structure is the for the welfare of the whole community, the people are also committed and responsible for bringing their contribution to this welfare in the form of taxes, levies or in the forms of tolls. Laying electric pipes in the walls and setup electric boxes. The investigations conducted are:Neenu is a Civil and Structural Engineer and has experience in Design of Concrete and Steel Structures. Planning for bridge construction is required as it has huge impact on life of people.

This is considered as an initial step towards the planning of structures, that would finally bring up with a project that would be advantageous to the community in all aspects. This expensive equipment shouldnot remain idle, and must be used cautiously to obtain optimum advantage.Several loads act on a bridge, and the bridge is designed accordingly. Each foundation is suitable for specific soil strata, and the desired bridge characteristics. Scientists explain these natural forms and the existence of these laws with the help of certain In one or the other form, the scientists or the engineers make use of pre-existing technologies in nature, that the only difference is the method they used to undergo.Various scientific developments that are made by the engineers based on these; like bringing different alternative materials by Enhancement of quality of life of the people, are greatly facilitated by the bridge construction. It is recommended to pass through built-up areas, or high hills or through major basin or religious structures.The approaches have a reasonable proximity to the main road. Traffic Assessment. Thus, lighter materials are used that are arranged in suitable geometric structures, and it is ensured that the configuration is aerodynamically stable.Since bridge construction is an expensive project, it is essential that all necessary tests may be conducted prior to the actual construction. VIP members get additional benefits.Login to The Constructor to ask questions, answer people’s questions, write articles & connect with other people. Air at a fast speed is moved through the bridge model. This depends on how he chooses the technological dimension, which must be conducted at the conceptual stage of the project.The planning sequence for the construction of a new highway or a railway project is a major part of the project planning. In general, the major steps that are involved in the planning for the construction of a new project is mentioned below:The major steps that are involved in the planning for bridge construction are:c) Evaluation of alternatives, risk analysis, and final choiceA brief idea on each stage is explained in the following section.The decision of having a new bridge in an area is taken as a part of development of the society.

the social and the technological dimension.This concludes that he must evolve a structure that is acceptable socially at the same time economic, durable and efficient. Bridge Design, Planning, and Construction. CFRP cables, that gain a strength of 3300Mpa and modulus of elasticity of 165GPa, was also made. Different Stages of Planning in Bridge Construction.

Another example is the Honshu-shikoku connection, that has bridges across many islands in Japan. b) Preliminary design and costing Storing water on top of the roof. All Rights Reserved. Bridge design has benefited considerably due to the growth of computer programs. The channel in reach must is narrow and well defined. Molding.

The foundation and the superstructure design will need to be considered.

A good construction plan is the basis for developing the budget and the schedulefor work.

It composed of five box girders with a clear span of 20.4m.The development of carbon fiber reinforced polymer i.e. Hence before choosing the alignment for bridge construction, it is necessary to determine all the possible CD works and its effect.
