Paoe # CommentsM{1 1. We trave submitted our criteria and plans that we have air duc{s (for heat exhaust), as shown on the

plans, and the dimensions are 0.45m x 0.90m. There is also a detailed drawing of the said air duclsleeves, pages M-7 & M-9 of the plans we have submitted.

a. Question: ls the size we gave for ihe air duct chase/sleeve enough for each store at alfresco areato exhaust heat?

b. Provide standard detail of air ducl for heat exhaust, section and isometric.

Please reflect the details of our air-duct sleever/chase drawings we have submitted.Regarding Mechanical General Notes #8b., we don't have floor mounled ACCU, we only have wallmounted ACCU and we have submitted our detail drawings for this. Kindly refer it on pages M-5, M-

6, M-8, & A-94 of the plans we have submitted before. Please follow the drawing details to prevent

leak.Regarding Mechanical General Notes #14, omit this section since there is no elevator for this projec{.
