Methodology for calculating a (7) Seven Day A Week Survey

The typical methodology assumes a 5-day workweek, but the credit language is more broad, allowing for a more fiexible baseline that is more sutiable to your project. I would establish a baseline that actually makes sense for your project and go from there.Since the building is currently operating can you use current usage data to establish a baseline?

Reynaldo,

My opinion is that it would be fine to use a 7-day period for the survey, but if some regular occupants (e.g., workers) only work for some of the days, you'll need to account for that, and adjust the denominator in your percentage trip reduction calculations accordingly.

For example, if 200 people work 5 days a week, and 100 people work 2 days a week on weekends, the base number of one-way trips per week is 2400 trips (200*5*2 + 100*2*2).

You could conduct a survey at the end of the 7-day period that evaluated both the total number of days worked by an individual, AND the modes of transit for each of those days. This would put you in a good situation to perform the calculations.

Reynaldo,

Look to Page 10 of the SCAQMD's Rule 2202 - it has guidance on the 2 different ways of handling 7 day a week occupants. Essentially you have to sample 5 days when the majority of employees are scheduled to work - there is however other options reflecting the timing of the survey and days when you are allowed to survey like Tristan and Jenny have mentioned.
