As the Baderman Island facilities manager, the main reparation task before me is to escape $10,000 loss per week due to the miserable condition of the Visitors Center roof. The only solution of which is the replacement of the roof. The architect has offered three options are here to be applied for the replacement:
1. The installation cost of Asphalt shingles is $20 per square foot is $20, so the total cost for 10,000 square foot roof is estimated to be $200,000 Asphalt shingles. It will take one week in the installation of the roof. It simply means that the installation period will cause $10,000 more loss due to not being visited by the clients. Hence, the total cost reaches $210,000 in case of installing of Asphalt shingles roof. In addition, the installation will remain valid for the next twenty years, and no cost will be required during these years.
2. In case of the installation of tiles, per square cost will be $50 per square foot, with total cost $500,000 for 10,000 square foot roof. In addition, it will take three weeks for the completion of installation process, which will cost $30,000 additional loss as it will remain closed for the visitors for the next three weeks. The aggregate cost will be $530,000, while the lifecycle is expected to be 40 years.
3. The architect has given the estimation of $35 per square foot for the installation of composite tiles with the total cost $350,000 for 10,000 square foot roof. Since it takes two weeks to install composite tiles, so additional $20,000 will also be included in the expenditures making the grand total of $370,000, and the expected lifecycle is 30 years.
Hence, the installation cost of asphalt shingles is $160,000 lower than the composite tiles, while its installation cost is expected to be $320,000 lower than the installation of tiles on roof. Moreover, the installation cost of composite
