A steel pedestrian overpass must either be reinforced or replaced. Reinforcement would cost $52,000 and would make the overpass adequate for the additional 20 years of service if the overpass is torn down. The scrap value of the steel would exceed theremoval cost by $14, 000 if it is reinforced it is estimated that it's net salvage market value would be $16,000 at the time it is retired from the service. a new prestressed concrete overpass would cause $180,000 and would meet the foreseeable requirements of the next 20 years such a design would have no net scrap or market value it is estimated that the annual expenses of the reinforced overpass would exceed those of the concrete overpass by $3200. Assume the money cost the state 10% per year and that the state pays no taxes. Using FW method what is the equivalent future expenses of a new prestressed overpass? Using FW method what is the equivalent future worth of the reinforced overpass?

Suppose a pre-stressed concrete bridge project has completed its engineering design stage and ready to begin its construction. The project owner, however suddenly changes his/her plans to use steel girder instead of pre-stressed beam but retain the other bridge component materials as originally selected. All other bridge parameters such as the bridge width, span length, number of lanes, slab, parapet, diaphragm, abutment, etc remain unchanged. Comment and give reasons on the anticipated changes in the engineering design that need to be addressed in terms of : (i) the live load (ii) the dead load and superimposed dead load (iii) backfill (iv) shrinkage, temperature & creep and wind
Load combinations for LRFD are given in the NSCP 2015 or ASCE 7 as follows. Combination 1: 1.4D Combination 2: 1.2D+1.6L+0.5(L, or S or R) Combination 3: 1.2D+1.6(L, or S or R)+(0.5L or 0.5W) Combination 4: 1.2D+1.0W+0.5L+0.5(L, or S or R) Combination 5: 1.2D±1.0E+0.5L+0.2S Combination 6: 0.9D±(1.0W or 1.0E) Given: D = 107 kN, L = 46 kN, L, = 19 kN, S = 20 kN, E = 50 kN, W = 40 kN Required: Which of the following is the controlling load combination for ASD?

Calculate the cost per cubic yard to place concrete using each of the alternatives described. The work in both cases consists of placing 140 cubic yards of concrete in footings. a. Using a crane and bucket at a price of $225 per hour, including an operator, with a crew consisting of 6 laborers, a cement finisher, and a foreman. The concrete will be placed in 7 hours using this setup, and transportation of the crane costs $390. b. Using a concrete pump at a price of $295 per hour, including an operator and a crew consisting of 5 laborers, a cement finisher, and a foreman. With this setup, concrete is placed in 6 hours and transportation of the pump costs $290.

A transit concrete mixer truck gets stuck in traffic and arrivesjust after the maximum time allowed for fresh concrete. Theproject superintendent rejects the concrete, but the driverinsists that it is visible still in good shape. However, becausethe superintendent refuses to accept the concrete, it is dumpednearby the project. Who should pay for this concrete?
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?
