BIDNG & CONTRACT REQUIREMENTS ALL REMNING BID PACKAGES BID DATES AND TIMES REMN UNCHANGED. Bid Package #6 Scope of Work: REPLACE Specific Inclusions Item No. 8 with the following: 8. HVAC hydronic piping from chillers into the building. Note that chiller piping sleeves are being furnished and installed by others. Top elevation of chiller pipe sleeves will be at 96.0, therefore minimum bury depth for the chiller piping will be -0 rather than the -0 noted on /M.0. Reference CM-0. CM-0 attached at the end of this addendum for reference. Bid Package #9 Scope of Work: REPLACE Specific Inclusions Item No. with the following:. Provide all sleeving (or core drilling when approved by GCCM) thru concrete for electrical work. Note that electrical sleeves along Gridline A are being furnished and installed by others. Top elevation of electrical sleeves will be at 96.0 and below, therefore minimum bury depth for the electrical conduit will be -0. Reference CE-0.
