The initial investment for constructing a median and guardrails for a prestressed concrete bridge is $1000000. Maintaining these facilities is expected to cost $2000 annually for the first five years of service and $10000 for the next five years of service. It is expected that these facilities will be rehabilitated at the end of the tenth year at a cost of $60000, after which the maintenance costs are expected to decrease to $6000 per year. What is equivalent uniform annual cost over a 15 -year period of service if the interest rate is 6% per year?
what are the different approaches to Preventive Maintenance Optimization (PMO)? Compare between them and show similarities, differences, strengths and weaknesses of each of them.
Q.4 (a) A new concrete bridge is to be constructed near the sea and its design has to incorporate features protecting it from exposure to marine environments. Among these, a new coating system is being proposed for concrete. You have been awarded a six-month contract to evaluate this system and materials involved. Describe the major parts of your programme, assuming that you also have access to a structure on which the coating has recently been used.
6.Give a short account on the construction of bridges in the upper, middle, and lower reaches of a river in relation to its flow pattern, erosion, deposition, and transportation characteristics. 7.List the types of materials required for the construction of a bridge. Where do you expect to find such materials? Explain the type and percentage of deleterious minerals whose presence in concrete is harmful in bridge construction and add a note on how the problem can be solved.
