USACE Scheduling Requirement in RFP

Hello all! I have a question about what planning unit (Calendar Days vs. Working Days) we should use in responding to a US Army Corps of Engineers RFP on a large capital project.

In the technical rating factors, it states "...The summary schedule should be task oriented, indicating the number of calendar days, after notice to proceed, by which milestones and phases are to be achieved." And later it states "The proposed project schedule should reflect the proposed contract duration and show the following milestones by building and phase as a minimum (use calendar days):" followed by a few milestone activities.

My team is interpreting these requirements to mean that all activities in the schedule should be based on calendar days (7 days/week) vs. the planned (and required) work schedule of 5 days/week. I am interpreting it to mean that we need to show how many calendar days after NTP our schedule shows we need to achieve these milestones, which I would accomplish with LOE summary activities; I am not anxious to plan everything on a bogus weekly schedule.

Has anyone else had experience with this?

Thanks,  Alex
