A parking facility on a campus was recently opened to faculty,staff and students.It cost a total of $ 300,000 to construct the facility. It is expected that thefacility will require no maintenance for the first 2 years ofoperation.At end of year 3, the first maintenance is expected to cost $2500 with an increase of $300 every subsequentyear thereafter. the campus would like to recoup the totalconstruction cost of the facility within the first 10 years ofoperation. Annual parking decals will be sold to payoff the structure. The interest rate is 7%. What should the annual decal rate be to cover the initial cost and maintenancecosts for the first 10 years of the facility's life? The facilityhas 100 parking spaces.
A blimp is approximated by a by a sphere of 25 m in diameter. Estimate the weight of 15°C gas within the blimp for (a) helium at 1.1 atm; and (b) air at 1.0 atm. What might the difference between these two values represent
The station and elevation of the PVI is 8+17.36 and 76.85 ft. Assume that there will be stakes placed at the PVI, BVC, and EVC, the low (or high) point, and at all the 100-ft stations.
Given the initial effective stress state at a point within a soil mass (s_y=2.5 daN/cm2, s_x=1.5 daN/cm2, t_xy=t_xy=0.4 daN/cm2) and effective soil shear strength parameters at the same point
Why do owners prefer the design-build form of contracts when many of them know they can obtain better quality construction using other forms. What are the stages at which the designer will schedule design reviews.
The maximum flow rate of a standard shower head is about 3.5 gpm and can be reduced to 2.75 gpm by switching to a low-flow shower head that is equipped with flow controllers. Consider a fam- ily of four, with each person taking a 6-minute shower e..
