A Design of Prestressed Concrete Bridge, Unpublished Project Paper for the degree of Bachelor of Science in Civil Engineering, College of Engineering and Technical Department, March 2015. This project study is about the design of prestressed concrete bridge and has the following objectives: (a) to design a prestressed concrete bridge that will serve as an alternative route to lessen the traffic jams in major highways of Lucena City; (b) to develop architectural and structural lay-out and plans for the design bridge; (c)to prepare technical specifications, bill of materials, program of works and cost estimates; and (d) to fabricate the prototype of the designed bridge. The design procedures used in this project study are as follows: (1) data gathering which includes site investigation, subdivided into two phrases namely; the socio-economic condition and the engineering viability aspects. (2) perform a soil analysis aimed of pointing the most appropriate structural design such as the kind of foundation to be used (3) provide structural plan which comprises of preliminary working drawings while computing for the structural design analysis of superstructure and substructure of bridge using the appropriate technical specifications and applying the concept and fundamental principles of prestressing of concrete. (4) to estimate the appropriate worth or total cost of the proposed bridge based on the current price of the construction materials. (5)to prepare program of works in order to organize and be easily understood the sequence of work or the phasing of construction; and (6) preparation of technical specifications which serve as guide and basis for the structural analysis and design of the proposed project study. Upon completion of all the necessary data needed for the project study, the researchers found out that the prestressed concrete if well designed, acquired high fatigue strength under 17 PRESTRESSED CONCRETE BRIDGE heaviest load and need almost no maintenance. Also the proposed bridge helps minimize the traffic in the city. From findings, the researchers come up with the conclusion that the proposed design of prestressed concrete bridge will lessen the traffic jams especially during peak hours. The attached structural and architectural layout and details are appropriate and feasible for the proposed study. Cost estimates, bill of materials, programs of works consistently aligned with the technical specifications of the proposed structure. Based on evaluation, the prototype has functioned according to its safety, economic and aesthetic purposes. With this, the researchers recommend the application of prestressed concrete for composite bridge construction being economical and as a result in crack free structure. Post tensioning method is highly recommended for practical and safe structural analysis of bridge. Since the project study is feasible, the researchers recommend to the concerned government officials the immediate implementation of the construction of the proposed bridge. The researchers also suggest the use of bored piles as piers for the purpose that is safe for design and much cheaper than any other piers.
