Element 4 - Economic Aspects
Task 4.5 - Cost and Performance


The goal of Task 4.5 is to work with other members of this project in the development of various Index Buildings to be used as models during the project. The Index Buildings will consist of a small house, large house, town house and apartment building. Detailed drawings will be developed for each building to be used by all participants to evaluate. Building specifications will be developed identifying all building parts. Detailed costs associated with building these buildings will be developed. As other members of Element 4 develop damage assessments and design upgrades, YOUNG & Associates will detail the costs associated with these damages and/or design upgrades.


The development of the Index Buildings will exemplify buildings that have been built in the past and are now being built.

The small house will be approximately 1200 square feet, 1 story, simple layout with 2 bedrooms and 1 bath built prior to 1970.

The large house will be approximately 2,500 square feet, 2 story, 3 bedrooms and 3 baths, recently built and engineered.

The small townhouse will be approximately 1,500 – 1,800 square feet, 2 story with part of structure over 2 car garage, 3 bedroom and 2 bath, recently built and engineered.

The apartment building will consist of approximately 10, 800 square feet units, ground level parking, built prior to 1970 with some engineering.

Technical Approach

Costs developed for the construction of these buildings and associated repairs or upgrades will be present day construction costs and will be based on acceptable industry standard unit costs. Area multipliers will be used to adjust cost to various locations.

Unit segment costs will be developed for certain parts of the buildings to allow for evaluation for repairs to a particular area. For example cost associated with replacement of a damaged aluminum sliding window that would include the cost to remove and replace the window, repair the exterior/interior finishes and any other construction cost associated with that task.

Delineation of Roles

YOUNG & Associates will interface with EQE International and California Institute of Technology performing Task 4.1 "Improving Loss Estimation For Woodframe Buildings" and Kelly Cobeen S.E. with GFDS Engineers regarding any engineering or structural issues. Tom Tobin will be YOUNG & Associates’ contact for all communication regarding the wood frame project.
