DATE: December 02, 2019

PROJECT: SON 520 Lab Storage Requirements & Prep for Future Offices

ITB NO: 744-B2008

OWNER: The University of Texas Health Science Center at Houston

TO: Prospective Proposers

This Addendum forms part of and modifies Proposal Documents dated, November 06, 2019, with amendments and additions noted below. 1. Clarifications, Questions and Answers:

1. Question: This RFP package only includes MEP drawings. It appears that the design intent is to

have new offices built out; however, there are no architectural drawings/specifications showing

the architectural scope. Please advise if the architectural scope will be part of this project or done

by others, after the project is completed. Answer: Project only includes MEP. Architectural will be performed by other prior to contractor

mobilization. Follow-up Question: If architectural will be performed prior to us mobilizing, we

would highly suggest only building the walls & waiting until after this project’s MEP scope is

completed before installing the ceilings. Perhaps this can be further clarified in the official pre-

bid addendum Q&A. Answer: ARCHITECTURAL WORK to be completed prior to Mech.

Work will be coordinated – walls will be left open near deck for ducting and conduit runs

2. Question: The existing sprinkler piping that is pointed up is currently painted red. Please confirm

the requirement for the new sprinkler piping to be painted red.Answer: Yes, maintain pipe color

for any sprinkler pipe changes. Follow-up Question: Based on the walkthrough, it sounded like

the sprinkler scope will be eliminated since the ceiling scope will be performed by others

Answer: Correction to previous response – Sprinkler scope by others

3. Question: Specification section 21 13 13 (sprinklers) calls for extra sprinkler heads as part of the

extra materials section in the spec section. Please confirm this is required for this project.

Answer: Yes, extra materials is required. Please provide Qty. (3) Follow-up Question: Same as

above. Seems the fire protection scope will be eliminated. Answer: Correction to previous

response – Sprinkler scope by others

4. Question: The existing piping and/or pipe insulation in the room is not painted. Please advise if

the piping and/or piping insulation is to be painted per the 23 00 00 specification.

Answer: Yes, Painting of insulation should be included per specification.

5. Question: Specification section 23 05 93 indicates that testing and balancing is by owner. Please

confirm for record.

6. Question: The existing piping insulation in the room is not currently jacketed with PVC nor

metal; however, the specifications call for jacketing. Please advise if jacketing will be required on

this project.

Answer: Jacketing will be required per specifications. Follow-up Question: If jacketing is

required, is the expectation for the jacketing to be painted? Usually jacketing isn’t

painted. Answer: Confirmed – jacketing to be painted – color TBD

7. Question: Johnson Controls is the current BAS/Controls system in the building. Please confirm

the intent is for Johnson Controls to be utilized for this project for the BAS/Controls scope of

work.

10. Question: Specification section 23 21 00 details pipe flushing procedures. Please advise if this

level of flushing will be required. If not, please provide project specific flushing expectations.

Answer: Flushing is required and cannot be flushed through the equipment. Follow-up Question:

The flushing requirements in the specifications do not seem to be project specific (more-so for a

new build scenario). I assume the requirement will be for localized flushing with bypasses on

each end with a small pump. Please confirm. Answer: Means and methods will not be confirmed

– the flushing plan is a required submittal for review and approval.

11. Question: Please confirm ductwork and hydronic piping shop drawings are required prior to

fabrication?

Answer: Yes

12. Question: There are existing windows with a knee-wall along the north wall of the room. The

electrical drawings show outlets along this wall. Is the intent for the circuitry/conduit to be

surface mounted on this wall? Or possibly routed beneath the raised flooring and up through the

knee wall from below?

Answer: Surface mounted conduit is acceptable

19. M2.0 states there will be a ceiling. If so, please provide an RCP and ceiling specs.

Answer: No ceiling in freezer enclosure. Follow-up Question: Ceilings will still be in the offices.

In the job walk, it sounded like the light fixture scope would be removed from the project. If so,

this question is irrelevant. Answer: Ceilings for office area are for ‘FUTURE BUILD-OUT’ -

question is irrelevant.

20. M3.0 lists Note 3 and 4; however, neither note is referenced on the drawing itself. Please advise

where these notes are applicable.

Answer: AThe note 3 should read “from existing connection” not “to existing” and should be

located at the connection point symbol by each FCU. The note 4 should replace the note 2

pointing at the dotted lines.
