Question 34. WP‐1 (Wall protection – Rail) is called out on sheet A‐610 in the Miscellaneous

Finish Material Legend. However, the WP‐1 does not show up on the Room Finish Schedule for any room. Sheet A‐301 / B‐1 Building Section shows a product that appears to be a chair rail or a wall protection rail but it is unclear where the product goes and what the product is. Specification section 066116 is specifying a solid polymer product but does not say it is for the Wall Protection Rail. Please clarify product material and where wall protection rails are to be installed.

Answer 34. Refer to General Sheet Notes #13 on all three floor plan sheets. The note refers to the use of Continuous Wall Guards as shown on Sheet A‐001. On Sheet A‐001, under

Control Joints, Fixtures and Devices, a note at the far‐right points to the Wall Rail and states "Install Bumper Guards at all Corridors and Lounge Areas". Revise this note to read "Install 4‐inch tall x 3/8 inch thick Wall Protection Rails at all Corridors and Lounge

Areas at the height indicated". Specification Section 06 61 16 describes the solid polymer product to be used as Wall Protection Rails (WP‐1). Disregard the Material

Legends Chart on Sheet A‐610. It will be revised and distributed NLT 11‐15‐19.

Question 35. Can you give us some direction on the factory finishing specification for the millwork in Section 06410 Custom Cabinets ? The finish system typically utilized for this type of project would be the AWI Systems 2,3,or 5 with the required defect sanding prior to stain and sealer and sealer sanding before top coats . These are the type finishes utilized on previous

TANG project Bldg 406. Please advise

A verbal question was posed regarding the vented attic as it relates to heating and cooling loads. Our mechanical engineers verified that the FCU’s on the 3rd floor have been sized to account for the additional heating and cooling loads from the vented attic.

Therefore, the attic shall remain vented, and the thermal envelope formed by the rigid insulation placed on the new sloping metal trusses and decking shall remain as designed.
