PROPOSALS WILL NOT BE ACCEPTED.

BILLIE JO CHEIRCO

14A. FOLLOWING ARE QUESTIONS ASKED FOLLOWED BY THE ANSWERS
:


Q1. Project bi ds on Tuesday July 27
th
, but the deli very location is Leavenworth Kansas. Is there a St
Louis location the bids can be deli vered to? Otherwise, our bids must be completed and Fed
-
Ex’d on
Monday…Monday is always a difficult day to bid after a weekend!

A1. To be answered by VA.


Q2. Is the ceili ng work required for the 6
th

fl oor asbestos removal (sheet 1/HA101) shown on the
drawings?

A2. Associated ceiling work for asbestos removal is not
specifically
shown on drawings.


Q3. Keyed Note

#1 on 1/AS102 tells us to “refurbish and

repai r” windows
AFTER

the walls that currently
cover the windows have been demo’ d. How do we know what repair and refurbish will be requi red when
the windows cannot even be seen until after demolition? Use allowance?

A3.
According to the VA, the wi ndow
s are presumed to be in good condition. They will need t o be
cleaned, trim to be painted, window treatment added and other minor repairs in order to match the other
existing windows. Any unanticipated extensi ve work to the windows will be negotiated with

t he VA at the
time of uncovering the windows.


Q4. Keyed Note #3 on 1/AS102 tells us to raise the slab in the areas noted with #3, +1/2” from the exiting
slab.
BUT
, we are never gi ven any
defi niti ve

“START” or “STOP” points. Example would be the 3 in
C
orridor H711…where do we start and stop the raised slab? How many SF of raised slab do we include in
our bid for all of Keyed Note #3.


A4. +0” locations are shown on 1/AS102 at the door locations of the rooms where elevated slabs are
required. +0” is
assumed to be top of existing structural slab. The following rooms are to be raised +1/2”:
B723, B725, B705, B706, B709, B710, B713, B714, B715
, B717
. The following rooms are to be raised +1”:
B723A, B718, B712, B711, B708, B707, B704.

The intent is to pr
ovide enough slope in the Litter Baths
and Patient Tlt/Shwr B723A to have an effective positive slope to the drain.



Q5. Wall header detail #5 on 1/AS301 shows 2 each 90 degree angle “
some

things
” at each side of the
wall, BUT the “arrow” calls out those 90 degree angles as “1/8” thick firestoppi ng sealant mastic”. Is this
correct? Are any angles required at the detail?


A5. No angles are required, only 1/8” thick fire
-
stopping sealant.



Q6.

There is only 1 page of elevations shown (1/AS501). In order to bid this job properly, we need
elevations for other areas…..”Phys. Dict. B728”


South, “Nurse Station B729”


West, “Soil B715”


North
& West, TYPICAL 8
th

floor “Exam” (Exam #1 thru #16), “
Nurse Office B861”
-

South, and any other “Nurse
Office” or “Office” that may need a “typical” elevation.



A6. Casework in the indicat ed areas (B728, B729, B715, typical 8th Fl oor

Exam,

B861, Nurse Office or
Offices) are NIC (not in contract) It is modula
r furniture to be supplied by the VA under separate contract.






Q7.
There are no el evations in any of the “Corri dors”. Corridor elevations could help us with the

bumper rail
and crash rail estimates.


A7. See drawi ngs AS/701
-
704 for locations of bumper,

hand and crash rails.

Line types are shown on
1/AS001.




Q8. The Door Schedule on 1/AS601 shows us 8 each Type ‘B’, “Metal Sliding Doors” and the elevati on for
Type ‘B’ shows a 4’ door. But, door opening B723 calls for a 3’ 6” door. Is this

correct?


A8.

Door opening B723 requires a 3'
-
6" door.



Q9. It appears that the remarks for Door A894A are shown at the wrong door (A895).


A9. The remarks on the door schedul e at door A895 do not apply to door A895, they apply to door A894A.




Q10. In the Equi pment

Schedule shown on 1/AS705, Item # F3010 (Claridge Bull etin Board) calls out
various locations and various rooms. Please provide the exact quantity of these items.



A10. Quantity of item #F3010 on the equipment schedule is

the responsibility of

the genera
l contractor.




Q11. In the Equipment Schedule shown on 1/AS705, Item # M1620 (Medi 0Crush Chart Holder) calls out
“various rooms”. Please provide the exact quantity of these items.


A11. Quantity of item #M1620 on the equipment schedule is the responsib
ility of the general contractor.




Q12. On the Fl oor Plans, Elevations, and Door Schedule, Corner Guards are
ONLY

shown on

One side of
the “Metal Sliding Doors”. Is this correct? There are no other corner guards to be

bid on this project?



A12. See draw
ings AS/701
-
704 for locations of corner guards.




Q13. On 1/AS705, there is no spec gi ven for Item

A5210A


“Wall Mounted Television Bracket” as are
given for the 2 brackets listed below this one.


A13.

Contractor to coordinate bracket with VA supplied
television.




Q14. On sheet 1/AS602, the Keyed Note ‘W1’ shows up in the remarks column in 28 rooms on the 8
th

floor. Basically, ‘W1’ = 2’ 6” x 4’ of HVW (Hygi enic Vinyl Wallcoveri ng). There is no other pl ace on the Room
Finish Schedule that indicates HV
W. Please confirm that these 28 locations of ‘W1” are the only HVW
required on this project.


A14. Hygienic Vinyl Wallcovering is to be used where i ndicated by keyed note "W1".

There are 26 lavatory
locations on the 8
th

floor where this occurs. Keyed note

“W1” also occurs in Soil A892, Jan A874 and Jan
B724. At the Janitor closets HVW is to be used to a height of 4’
-
0” on all three sides of the mop sink. At Soil
A892 HVW is to be used on the wet wall of the clinical service sink to a height of 4’
-
0”.




Q15. The Finish Legend shows a ceramic tile floori ng but none is called out of the Finish

Schedul e. Is this
correct?

A15.

Correct, the ceramic tile shown in the finish legend is not used on the finish schedule.




Q16. Sheet 1/AS801 shows the typical sink cabinets, patient lavs, and met al casework to have solid
surface (Corian) tops. Can we assume that ALL countertops on this project are solid surface tops?


A
16

A
l
l countertops are solid surface except for the ‘sel
f
-
care lavatory’ detailed on 1/AS801 and l ocated in
the following rooms:
B723A, B718, B712, B711, B708, B707, B704
.




Q17. The Finish Schedule shows only 4 rooms to get wall fi nish ‘SC’ (Polyester Epoxy Coating). Do any of
the rooms with a resinous coati
ng wainscot get the ‘SC’ finish above the wainscot?


A17.
The Fi nish Schedule Legend clearly identi fies WSCT as “Resinous Wainscot Integral w/ Floor and
Base;
SC above
.” Note that WSCT has a different definition from WSCT
-
1.




Q18. Rooms A856 & A867 sh
ow concrete floors. Will those floors get an epoxy finish?


A18.

Rooms A856 and A867 shall have exposed concrete floors.


No epoxy finish in these areas.




Q19. General Note #13 on the Cover Sheet (1/GI001) says that
ALL
gypsum board used on this project

is to
be moisture/mol d resistant. Please veri fy that this is correct as the Partition

Types do not tell us this and the
Gypsum Board specs conflict. Telling us in 1 place (Page 2,
paragraph 2.1, A) to use “Water Resistant
Gypsum Board” and then in another

pl ace (Page 3,

Paragraph 3.2, C tell us to use “Moisture AND
mold
resistant assembli es”. If you would gi ve us

specific instructions and/or specific gypsum products to use in
specific locations, that would help the drywall subs tremendously.


A19. Use moi
sture/mold resistant Type "X" gypsum board in all locations
.



Q20. There is only one detail showing both the ceiling hei ght and the deck above (det 9 on sh
e
et
1/AS601). This detail shows the deck to be 3”

taller than the c
eiling height @ 11’ 6”. Is th
is a correct deck
height?


A20. The floor to floor heights shown on the existing drawings are as follows:


6
th

floor


7
th

floor 11’ 0”

7
th

floor


8
th

floor 11’ 11”

8
th

floor to 9
th

floor (roof) 11’


5 ½”

All heights to be verified by contractor.



Q21. Can the el evators be used for material stocking and are there speci fic elkevators and/or times that
we are limited to for material stocking.


A21. Refer to Spec Section 01 00 00, General Requirements, 1.19 Temporary Use of Existing Elevators.



Q22.

On 8
th

Floor Demo Pl an 1/AS103, Keyed Note #3 tells us to fill in openings where roofing mechanical
equi pment has been removed and to patch roofing. The HVAC drawings to NOT show any rooftop
equi pment demo, do NOT show the size of the holes to be “fille
d
-
i n” and do NOT show the amount of
roofing to be patched. Please clarify. IF this equi pment has already been demo’ d by others, then we just
need number and size of openings to patch and SF of roofing to patch.


A22. Rooft op equipment shown demo’d on sh
eet 1/MH103 keyed notes ‘3’, ‘8’, ‘20’, ‘23’ and ‘24’ on
PARTIAL EIGHTH FLOOR


VENTALATION DEMOLITION. As far as R&B is aware, this equipment is
still in place. The approximate area of existing slab to be filled in is 10 square feet. This is to be veri
fied
by the contractor.



Q23. What type of roofing currently exists above the 8
th

floor demo? (Where patchi ng occurs). Would
this roofing still be under warranty by any chance?


A23. Access to the roof was not avail abl e: the roof is presumed to be EPD
M. Accordi ng to the Va Project
Engineer, there are no warranties over the roof in this area.




Q24.


Please specifically identify any work that will be required to take place during times OTHER than
normal working hours.

A24
.

Refer to Addendum #1, Contractor Notes.


Q25


Please refer to 7th floor elec. power/systems, sheet 1/ES104. Will “Litter baths” B718 and B704
require radiant ceiling panels like the other bathrooms on the 7th floor? None shown.

A25


A

radiant ceili ng heating panel will be added on sheet 1/ES104 for room B718, but it is not requi red for
room B704.


Q26. We have painting contractors asking for speci fications/products for wall finish ‘SC’ as shown on the
Finish Schedule and the Finish Le
gend on sheet 1/AS602. (Polyester EpoxyCoating)


A26
.

Refer to Master Painters Institute publication MPI 77 as called out on sheet 1/AS602 ‘FINISH
SCHEDULE LEGEND’ for finish ‘SC’.


Q27
.

On sheet 1/ES101 it says; “All telephone/data cabli ng shall be fu
rnished and installed by the EC and
terminat ed by the OWNER (VA)”. BUT, on Sheet 1/ES108, General Notes For Tel ephone/Dat a/TV, it tells
us (the EC) to furnish, install, and terminate the jacks. Please clarify these conflicting instructions.

A27
.

The EC s
hall terminate the jacks as per the note on sheet 1/ES108.


Q28. Same issue with the TV cabling as my item #27 above. Sheet 1/ES101 says all cabli ng, jacks, & plates
by the owner. But info on Sheet 1/ES108 conflicts with that statement. Please clarify.

A
28
.

The general notes on the riser on sheet 1/ES108 apply only to data and phone outlets. The TV jacks
and plates are by the owner’s TV equi pment/system supplier, as indicated in the typical combination
TV/120V outlet detail, on sheet 1/ES108.


Q29
.

She
et 1/ES101 simply identifi es an speaker/paging system and Keyed Note #2 on 1/ES104 also
references these items. But we are never gi ven any specifications for speakers or type of cabli ng requi red.
Please clarify.


A29.

As per not e 2 on sheet 1/ES104, spea
kers and back boxes are to be suppli ed to match the existing
system and connected to the existing with wiring to match existing system.



Q30. The specifications call for ALL of the fire alarm cabling to be run in hard conduit yet none

of the other low vo
ltage systems/cabling on this project requires conduit. Is this correct? Simply

trying to save some money here
.


A30. The VA Fire Protection Design Guide does not address whether the fire alarm wiring is to be installed


in

conduit, however the VA guide specifications require all wiring for the fire alarm systems to be in conduit.

We did not edit this portion of the specification, therefore this requirement remains in the final

specification
. The contractor should install the fire alarm system wiring in conduit as specified in

the fire alarm specification.



Q31. The detail for the V/D symbol shows running one voice and 3 data to each of these locations. But,

the data closet detail says to

install an 88 port patch panel. Now there are 64 locations for that symbol on



the 8th floor. Are we to run the cable as shown on the detail and ADJUST the number of patch panels OR


is the detail wrong and we are really only to run one data cable to eac
h of the locations shown? Please clarify.


A31. The detail is incorrect in that there are to be 2 data cables to each outlet (not three). Patch panel and

wire quantities should be adjusted accordingly.



Q32. Are we to run a feeder/connector cable from
the new data closet to any other voice/data location

or closet in the hospital?


A32. No, it is our understanding that the VA will run any main cables from the new data closet to the main

data closet.



Q33. The telephone riser notes tell us to use CAT
5E cable for BOTH voice AND data, BUT on the voice

and data outlet detail, it tell us to use CAT5E for voice and CAT6 for the data cable. Please clarify which


one is correct.


A33. Use Cat5E for telephone (voice) and Cat6 for data.



Q34. On sheet
1/ES104, in Room B731 you show solid (filled
-
in) voice/data symbols. Please identify what


this symbol means compared to the other voice/data symbols.


A34. Ignore the filled in symbol. All outlets should be the same (combination telephone/data type).



Q35. Keyed Note #2 on 1/ES104 calls for J
-
hooks to be 2’ on center. Industry standard and all other J
-
hook



A35. 4’ on center is acceptable.




Q
36.


Question from painters; Painting specs (09 91 00) pages 9 thru 13 specify ALL Mechanical & Electrica
l


pipe to be painted. Painters have no idea as to the quantities of new piping and since there are currently ceilings
everywhere in the 2 spaces, have no idea how much existing pipe there is to be painted. Please clarify the

requirements and scope of thi
s work so the painters have some idea as to the quantity of pipe to be painted.


A36.
Specification section 09 91 00 3.9 covers painting of new non
-
factory finished mechanical and electrical

items within finished spaces (not above ceilings). Section 3.11

covers
identifying
new mechanical and electrical

services

by stencil, pressure sensitive vinyl markers or snap
-
on coil plastic markers. The spec does not say that all
electrical and mechanical piping is to be painted. Quantities need to be coordinated w/the mechanical and electrical
contractors.

Rescue hardware is not required on doors B732, A857 & A858 or any other doors on the proje
ct.



Q3

. What is the Lock Key System for the facility, so it can be matched?


A39.

-

Russwi n Locking system with 59 A
-
1 removable
cores.



Q40.

Where can I find

the sign details or drawi ngs for the Repair Spinal Cord Inj ury project
(VA25510RP0327).

Sheet 1/AS902 indicates that "sign designations refer to VA interi or signs
document". Where can I view this document? Should I be looking somewhere else for sign det
ails


A40.
There is no signage provided by the contractor.

The VA has a major signage program that is
handled by Terry Pickles

He will provide signage after the project is complete.



Q41.

Does the Spec for Manufactured Metal Casework meet the VA requirements
?



A
41.

The A&E

has reviewed the specs and this spec will not meet the VA spec for Manufactured Metal
Casework.


The VA spec 12 31 00, 2.3 C. 1. calls for Welded Assembly.


The G
oelst Spec has various
locations (i.e. 2.3 B. 1.c., 2.3 B 2.c.)

that note that welding of components is not permitted.






Q42.
. Can set screw connectors for EMT be used for 2” and smaller as per the detail on sheet 1/ES108?


A
42
.

No. The specifications takes precedence and it only allows set screw connectors for 2” and larger.
