A7: Structural shows the framing height correctly adjacent to the new gallery. Q8: 1/A7.6 is called out on the west wall of the Gallery on sheet A6.5. It appears this is an incorrect

call out and should be detail 3/A7.6. Please confirm detail call out at the west wall of the Gallery, sheet A6.5, should be detail 3/A7.6. Please confirm detail 1/A7.6 is not used, or clarify the applicable locations

A8: See 100% bid package. Q9: Detail 5/S5.1 does not show the welding requirements for the ¼” plate assembly to the W

column. Please provide the welding requirements for the ¼” plate assembly to the W column shown in detail 5/S5.1.

Q36: See highlight below. We believe you intended to say 19.9.4? Also, we believe you want the “value engineering process” in 14.9.3 with the other processes of our technical approach?

A36: Reference Addendum #2; Change the response to question #4 to read: Reference Section 00100, Paragraph 14.9.3 DELETE “Discuss your Project Team’s approach to completing the project. Include any specific challenges to the successful completion of this particular project and how your team would approach them. State specifically the types of support or coordination required from members of the team, including the Owner and Architect and describe how this support assists in the successful delivery of this project. Describe in detail the phasing plan and how there will be a seamless transition between each construction phase. Outline how any impact to the educational program delivery in between summer construction phases shall be avoided. Lay out clear contingency plans for unanticipated interruptions to the school program.” Reference Section 00100 Paragraph 14.9.4 ADD “Describe in detail the phasing plan and how there will be a seamless transition between each construction phase. Outline how any impact to the educational program delivery in between summer construction phases shall be avoided. Lay out clear contingency plans for unanticipated interruptions to the school program.” Q37: Recently issued Addendum No.1 appears to have swapped the original due dates for the cost

and proposal submissions. Please advise. A37: See subsequent addenda for corrections. Q38: Given that there is a new site walk on Feb 23, please push the due dates for whichever is due

on Feb 22 to the following week. This will allow us to revise our proposal should we learn something new at the site walk. This would also rectify the issue of staff availability due to holidays and ASD closures that week.

A38: The second site walkthrough is scheduled for costing only. Site walkthrough is rescheduled due to Solicitation Suspension noted in Addendum #3.

Q39: Can the roof insulation and coverboard be mechanically attached through the entire roof
