On plan page A-2 there is one sidelite in the training room on the second floor. Will demountable frames be used in the interior? What is the height of the sidelite? Is there any areas needing fire-treated glass?

Answer: Sidelites shall be full height of the door they are adjacent to. Demountable frames are not a requirement for this project. Determination of fire treated glass is the responsibility of the Design/Build Contractor and shall comply with section 1800 1.10 and applicable codes and criteria.

23. Does the Government have any reason to believe California Environmental Quality Act (CEQA) review is to not be required for this project?
