Questions & Answers The following are the responses to questions received during the call period: Q1) Drawing 3/A-301 (Existing Block and New Veneer Wall Section): This section is incorrect because it doesn t show the metal siding, from the top of the wall, observed during the site visit.

A2) Ceiling in the heated seated and viewing area to be removed and replaced completely. Q3) Drawing A-601: Concerning the hardware, the specifications mentions 7 hardware groups and to refer to the drawings for each door hardware requirements, but, the room finish schedule shows only none in the detail group column of the door schedule.
