Assignment 5: Outline specifications and life cycle costs

Issued Oct. 4, 2017
Due Oct. 11, 2017 (in class)

Part I: Outline specifications

Write a (partial) outline specification for Milstein Hall, as follows:

  1. Review the sample specification [.doc] here or as excerpted in the class notes from lecture 7a.

  2. You may refer to my Milstein Hall construction videos to get some ideas about possible products and systems used in the building.

  3. Choose one specification section each for divisions 03 through 09, and write an outline specification corresponding to what appears in Milstein Hall. If you're not sure what a particular product or system is, make your best guess — it need not be entirely accurate, only plausible.

  4. For each of the seven specification sections chosen, include a photograph (or screen-captured image from one of my Milstein Hall construction videos) of the item as installed in Milstein Hall — along with a caption explaining what and where it is.

  5. Check the list of Masterformat numbers and titles for ideas about which section number to pick for each of the seven divisions (i.e., divisions 03 through 09). For example, if you were to choose something in division 02 (you're not!) it could be 02 32 13 Subsurface Drilling and Sampling. Another choice could be 02 41 91 Selective Historic Demolition. And there are many other viable choices for each of the divisions.

  6. The text and other course references are also valuable resources for information on products and systems.

Part II: Life cycle costs

  1. Select the best parking lot paving product (of the seven listed in the BEES software) based on life cycle costs only (excluding consideration of environmental impact). Use the BEES online tool (click on "BEES online"), using their default settings for transportation distance and discount rate (2.7%). Your initial settings should look like this:
    initial BEES settings

    Click on "next." Then, after selecting each product (click on "select alternative"), click on "compute." View report after the calculations are complete (!).

    Based on total lifetime costs and a 2.7% discount rate, what is the most economical product?

  2. Start again (you may need to go back to the BEES online tool original link), but this time set the discount rate to 12% — this corresponds to a more robust economy than the one assumed as a default by BEES. Again based on total lifetime costs, but this time with a 12% discount rate, which is the most economical product?

  3. Briefly discuss the two scenarios (2.7% vs. 12% discount rate): why are the results either the same or different?

Format: Submit on 11 x 17 inch paper with border and title block.

You are encouraged to work in groups consisting of 2 to 6 students. To facilitate NAAB documentation, each group should consist of either undergraduate or graduate students, but not both.
