The purpose of this addendum is to provide information to Bidders.
: :
Bidders are advised as follows:
1., Question: According to the plumbing demo drawings, we will be cutting, removing, and
replacing the floor slab in neighboring office 135 and corridor 133 on the first floor. There
is no mention of the removing or replacement of the existing finish flooring or its
* type. Please advise.
Answer: /t is not anticipated that saw cutting in rooms 135 & 133 will be
, required, the dashed “saw cut line” is approximate and to be field verified, refer to
| response #2 for additional direction.
2.’ Question: It seems the slab cutting/removal/replacement and digging in the corridor on
_ the first floor, as shown on the plumbing drawings, may be being performed just to
' remove a section of soon to be obsolete pipe. If that is the case could that section of pipe
simply be abandoned to avoid a major disruption? Please advise.
Answer: Yes, obsolete under slab piping can be abandoned in place to avoid
; major disruptions, abandoned pipe is to be capped and filled with concrete with no
‘ open ends.
3.! Question: Considering the smail amount of concrete floor patching involved, can the
| requirement for ACI certification for the installers be waived?
| i
Answer: Yes. The larger ACI accredited companies are very unlikely to be
interested in bidding on a project of this size. .

Barrier One. Is this the correct intent?
