PRE-PROPOSAL QUESTIONS

Questions Due February 4 @ 4:00 PM Proposals Due February 13 @ 4:00 PM

VA Clarifications:

1. For Sheets P101 and P201, the 2” CW horizontal line that the new women’s is tapping into stops above the men’s restroom. So, there is no existing branch line over to the women’s, it would be all new.

2. There is no decking on the existing women’s and men’s ceiling to work from.

Questions and answers listed are the following pages. The original question is pasted in black font and the VA response is in red font.

Received January 27 @ 2:33 PM

1. Q: I did not see any vent lines in the new women’s restrooms for any of the water closets. Were the vent lines run below the floor? If so, that would be a wet vent and I’m not sure the inspector will let that fly.

A: All vent piping is new except for the VTR. Also, on Sheet P201, diagrams 1 and 2 should be switched. They currently reflect the incorrect rooms.

2. Q: It looks line the underground piping for the new women’s restroom has already been installed. Is this a safe assumption?

A: Refer to Sheet P101, which shows existing versus new piping and floor drains.

3. Q: I noticed that the 2 new floor drains were not installed and would require saw cutting more concrete out in order to install them. Do you know the size, material type and depth of the existing drain?

A: Unknown, the new drain locations and sizes are shown on Sheets P101 and P201.

- It appears that the layout of the water closets as roughed in for the Women’s Restroom 203 does not match the drawings as shown on sheet P101 as issued by Baird Hampton Brown on 03/08/2019.

o Q: Is it the intent of the VA to utilize the framing and plumbing piping installed for the new

Women’s Restroom 203 as viewed on the job walk, even though it does not meet plumbing code requirements?

A: It is VA’s intent to meet the code requirements per the City of Lancaster and TAS.

Some piping may need to be modified/adjusted to align with the fixture layout. The fixtures, per the design, have been located to meet code and comply with TAS.

o Q: Is it the intent of the VA for the sanitary sewer, sanitary vent, and domestic water piping to be installed as shown on the Plumbing drawings dated 03/08/2019?

A: Yes. All vent piping is new except form the VTR. Also, on Sheet P201, diagrams 1 and 2 should be switched. They currently reflect the incorrect rooms.

o Q: If the intent is for the new plumbing piping to match the drawings issue, the wall framing will have to be removed for the correction of the plumbing piping installed for women’s restroom 203.

A: The intent is to meet the code requirements per the City of Lancaster and TAS.

- The phasing plan on AD101, issued 03/08/2019, indicates the rework of the Existing Men’s restroom 203, to be performed during Phase 3. Once the work of Phase 2 for the Existing Women’s Restroom 202 has commenced, due to sharing the chase wall and sanitary lines, the Existing Men’s restroom 203 will be out of commission. Would it be possible for Restrooms 202 & 203 to be taken down during the same phase and utilize the Men’s Lobby Restroom for the duration until New Men’s Restroom 202A and 202B are completed?

o Q: If the Lobby Men’s restroom cannot be utilized in this manner, will temporary doors and wall partitions be required for in the New Women’s Restroom 203 to allow for separate men’s and women’s water closet usage, and utilize the lavatory space as a common area until construction is completed?

A: During the interim, the lobby restroom cannot be utilized for all men’s restroom usage, and the new women’s cannot be separated. The contractor needs to provide a plan that limits the downtime to utility tie-ins.

- Q: Is the area above the ceiling in the existing space considered a return air plenum?

A: Negative. The return air is at the new unit as shown on Sheet M101.

- Q: Will the use of carrier mounted, wall hung water closets be permitted?

A: Negative. Refer to the 03/08/2019 P Sheets and 12/12/2019 Bidding Addendum.

- Q: Is the plumbing in the common chase on existing restrooms 202 and 203 above the floor or below the floor? (If it is Below the floor all those walls have to come out, To remove the concrete.)

A: Refer to Sheets P101 and P102. Plumbing connections are above floor. Water closets are floor mounted with a rear outlet connection.

- Q: If we have to remove spoils and concrete To the outside. Can we use motorized wheelbarrows?

A: Motorized wheelbarrows that are not gas or diesel may be utilized but will need to be approved prior to use.

Can you please advise how to proceed with choosing a color group?
