Where can I find information on life cycle costs for building materials? Mainly I am looking for information to give to an owner concerning when they should expect to replace a material. |

David,
Please check out RS Means' Facilities Maintenance & Repair Cost Data. Here are some examples: Roofing: Non-destructive moisture inspection- every 5 years; Total roof replacement- 28 years. Along with frequency in years, it also provides labor and materials cost data. Your local bookstore that sells technical books should have this yearly publication in stock. Good luck! |

Thanks Frederick!
We just ordered the book that you recommended.
Since my firm does a lot of historic preservation projects, we have been asked by owners to do existing facility feasibility studies. The LCA information will be very useful for determining what needs repair/replacement/removal. |
