001 Perkins Eastman 11/2/18 SMC 4 Marcelli Steel 1 11/1/08 Spec 05 12 00 1.05F states that the Steel Fabricator shall be AISC
certified. Can the AISC certification be waived?
AISC certification will not be waived. 11/5/18 1
002 Perkins Eastman 11/2/18 SMC 4 Steeltech Bldg. Products 1 11/2/18 Can the designation for the Erector to be AISC certified be waived? AISC certification will not be waived. 11/5/18 1
003 Perkins Eastman 11/2/18 SMC 13 Firestop Incorporated 1 11/1/18 There is a discrepancy between the FP Drawings and
Specifications with regard to classifications of areas.
Academic Areas are indicated as "light hazard" and Mechanical
Areas are indicated as "ordinary hazard". The spec further
identifies areas as ordinary hazard 1 and 2. The differences
between the two double the gallons per minute required for
light hazards. Is the .2 FPM over 3,000sf necessary? The water
pressure coming into the schools is already low and there is no
fire pump. There is a concern meeting the requirements
especially in the Gym and Library.
004 Perkins Eastman 11/2/18 SMC 9B & 9D M. Frank Higgins 1 11/2/18 The specs reference the finishes selected on the plans but the
majority of the Manufacturer, Style, and Color columns on IN-
601 are blank. 1) Please specify all finishes.
The Specification is performance based for
ceramic and porcelain tile. The resilient
flooring specification is also performance
based with 3 acceptable manufacturers listed.

011 Perkins Eastman 1/7/18 SMC 11 H. Weiss, Div of BHS 1 11/7/18 We would like to be added to the list of approved food service
contractors.
Delete articles 1.04;A.3 and 1.04;A.4 from
Specification section 11 40 00 in their entirety.
11/13/18 1
012 Rizzo 11/8/18 SMC 9D ProFloors LLC 1 11/7/18 Is this a Prevailing Wage Project? Is it tax exempt? Project is Prevailing Wage and Tax Exempt 11/8/18 1
013 Rizzo 11/14/18 SMC 15 MJ Daly 1 11/12/18 Spec section 00 41 26 is the proposal form, however there are
three sets of proposal forms (single package, combo bids within
1 school, combo bids for both schools). Since we will be doing all
three, did you want us to provide three separate submissions
per proposal form type, including all the paper work being asked
for in triplicate, all separately? If yes, would the individual bid
bonds suffice for the combo proposals, or are you looking for a
multitude of combo-bid bid-bonds as well?
Bid Form "A" gets all the required Alternates,
Unit Prices and attachments, all in triplicate.
The attachments to Bid Form "A" are
applicable to Bid Forms "A-1" and "A-2" so
duplication is not required. Just submit Forms
"A-1" and "A-2" in triplicate with no other
attachments. With regard to Bid Bonds, submit
a single bid bond with a cover letter from the
Surety indicating the bond is also applicable to
the bids submitted on Forms "A-1" and "A-2".
11/14/18 1
014 Rizzo 11/14/18 SMC 15 MJ Daly 2 11/12/18 Did you want Spec Section 00 45 13 “Contractor Qualification
Statement” submitted by a certain timeframe, or since we have
done work in the recent past together, are we already
prequalified?
Contractor Qualification Statement is required
to be submitted with all bids. See Spec Section
00 22 13 Item #12.

015 Perkins Eastman 11/14/18 SMC 5 Nova Wood Products 1 11/12/18 Interior Finish Schedule IN-601 says PL-2 is for FACULTY
MILLWORK and PL-3 is for CLASSROOM MILLWORK. The
elevation titles identify the type of millwork. Which laminate
colour is required at the elevations designated as OFFICE (e.g. A-
213/25)? Are office & faculty intended to have the same finish?
Office millwork shall have pl-2. 11/16/18 4
016 Perkins Eastman 11/14/18 SMC 5 Nova Wood Products 2 11/12/18 Plan view of the casework in 105 OT/PT shows the tall cabinet
on the left and the sink on the right. The elevation tag says “A-
213/16 Sim” (see A101a/1). The actual elevation on A-213 has
the tall cabinet on the right and the sink on the left. Are we
correct in assuming the plan view is accurate and the elevation
tag should say Opp. Instead of Sim.?
Yes. Tag should read Opp. 11/25/18 2
017 Perkins Eastman 11/14/18 SMC 5 Nova Wood Products 3 11/12/18 Enlarged plan view of the 101 Admin Suite shows a low wall &
gate adjacent to the reception desk (see A-401/2). Neither the
wall nor the gate is shown in elevation A-213/8 and there are no
section tags on the floor plan. Is there any millwork required at
the low wall or gate?
Provide swing gate and low wall at height to
match adjacent millwork. Provide spring
loaded closer and cabinet latch on office side.

018 Perkins Eastman 11/14/18 SMC 5 Nova Wood Products 4 11/12/18 Enlarged plan view of the 101 Admin Suite appears to show
something inside 101g Admin Coat Closet. No elevation tag or
section tag is provided. There are no section details for a coat
closet with the millwork details on A-551 through A-553. There
are no specifications for coat closet millwork or hardware in
section 06 40 23. Is millwork required in this closet?
Provide 12” deep shelf with PL-2 and coat rod
with appropriate hardware.
11/25/18 2
019 Perkins Eastman 11/14/18 SMC 5 Nova Wood Products 5 11/12/18 Please clarify what is required at the staff mailboxes. In elevation
A-213/13 they appear to be standard mail slots in an open
cabinet, presumably plastic laminate to match the rest of the
casework. Section detail A-551/4 has no notes to identify the
finishes at the mail slots, but it shows a back panel that appears
to match the rest of the casework, top & bottom panels and
shelves that are a different material, and no sides or gables at
all. The hatch pattern used at the top, bottom & shelves appears
to indicate wood of some kind (solid lumber or wood-veneer-
faced plywood), but the specification in section 06 40 23 do not
include specs for wood species, cut, or finish. If wood veneer is
used is it the same STAINED MAPLE that is used for the bench
seats?
Reference elevation A-214/13. Provide per
detail A-551/4. Use PL-2 for shelves, back
panel, side panels, etc.
11/25/18 2
020 Perkins Eastman 11/14/18 SMC 5 Nova Wood Products 6 11/12/18 There is a note at elevation A-211/1 for SOLID SURFACE AT
WINDOW BENCH at curtain wall CW-01 in 121 Cafeteria. The
section detail is A314/3. That wall section shows precast
concrete bench at those locations. Which is correct? If a solid
surface bench is required, please identify which solid surface
colour and provide a section detail for it.
Provide cast stone bench. 11/25/18 2
021 Perkins Eastman 11/14/18 SMC 5 Nova Wood Products 7 11/12/18 Section details A-553/2,4 include notes for SUPPORT BRACKET at
wall-mounted benches. Specifications in section 06 40 23 do not
include bench support brackets. Please provide specs including
manufacturer, model number, type of metal (steel or
aluminum), and finish.

not include a solid surface sill. Section detail A-322/5 is titled
SECTION DETAIL @ STAIR 1 – BOX W/PHENOLIC and it includes a
15” deep solid surface sill. Floor plan and enlarged plan for Stair

laminate & solid surface items. Quality Assurance in paragraph
1.06.A refers to sequence-matched wood veneers. Materials in
paragraph 2.01 include plastic laminate and solid surface, but
there are no specifications for wood veneers. There are notes
for STAINED MAPLE in the drawings at the bench seats on A-552
(both sets of drawings). Is it Natural Maple (with colour variation
between sap & heart wood) or is White Maple (sapwood only)?
Is it plain sawn? What face grade is required (“A” is standard for
transparent finishes like this)?
Provide Grade ‘A’ plain sawn Natural maple
wood veneer.
11/25/18 4
Specifications in 06 40 23 indicate there are three (3) colours
required for plastic laminate and three (3) colours required for
solid surface. They are identified as “As scheduled on drawings”
(see paragraph 2.01.D.2 and 2.01.E.2). Interior Finish Schedule IN-
601 indicates there are four (4) colours each but none of the
colours are identified.
a. Which is correct? Are there 3 colours for each or 4 colours?
b. Will specific colours be identified? Cost for plastic laminate
varies widely, depending on manufacturer, colour/pattern, and
finish/texture chosen. Cost for solid surface has an even wider
range, depending on manufacturer & colour/pattern chosen.

028 Perkins Eastman 11/14/18 SMC 5 Nova Wood Products 14 11/12/18 Specification in paragraph 2.05.C indicate the cores of the plastic
laminate casework is to be either medium-density-overlay or
veneer-core plywood. AWS standards require either
particleboard of MDF cores at doors & drawer faces because of
warping & delamination. Please confirm that AWS standards
take precedence over project specifications. (Note that if the
owner/architect insists on another core at the doors & drawer
faces, we will fabricate them, but they will not be covered by the
warranty.)
AWS standards take precedence. 11/15/18 1
Scope of work for BP5 and summary paragraph at front of
section 06 40 23 refer to custom display cases, however there
are no specifications in section 06 40 23 for custom display
cases. There are section details (A-552 for Johnson Elementary &
A-553 for Rockwell Elementary) but the details are missing quite
a bit of information and some of the notes contradict each
other:
a. There are no thicknesses for the tempered glass, just notes
that say “as specified”. How thick are the doors? Are the shelves
the same thickness or are they different?
b. There are finishes for the hardware, but no sizes,
manufacturers, or model numbers. Please provide specifications
for door hinges & locks at swinging doors, door track systems &
locks at sliding doors, and shelf standards & brackets at glass
shelves.
c. The small display cases have notes for both pivot hinges &
sliding doors – which is correct?
d. Please provide specifications for the fabric on the tack
panels in the large cases – manufacturer, pattern, colour, etc.

e. The tack panel in the smaller cases does not include the
description “fabric-wrapped”. Is it the same as the larger cases
or is it something else?
f. There are notes for hardwood veneer panels at the top of
the case. At the bottom there are notes for optional low-
pressure laminate (i.e. melamine) in walnut or oak pattern at the
top, bottom, and ends. Which is correct?
g. Who is responsible for the Reglet trim – millworker or
drywaller? If the millworker is intended to provide it, we need to
know the profile, size (width/height and depth – only the height

12/5/18 5Please clarify which sill is required at each window type. Each
drawing set has several different solid surface sill details. There
are no sill detail tags on the window elevations on A-610 & A-
611 in either drawing set to identify which sill goes at which
window type. We are trying to work from building elevations to
building & wall sections to determine which sills go where, but
that is difficult. We’re assuming all windows in the same stretch
of wall have the same sill detail. Some walls do not have any
section tags, so we’re trying to determine the wall type by
looking at the building exteriors so we can match it to the
description in the sill detail titles. Some walls are not shown on
the building exteriors. In addition, there are several locations
that have inconsistent/contradictory information provided.

floor slab extending into my storefront, which on the verticals
would be in the way. It shows right now separate frames stacked
on top of mullion extensions, which does not work. There is no
way to secure separate frames together using the mullion
extension, as well as there is no way of securing it. The way to
make this work, with the jambs not being intersected with slab,
is to hold the frames out, and use a clip or type of tie back to
secure. This would require some design changes. Please review
and provide a revision, as this is holding me up with pricing due
to the conflict.

have to install all components and have them fully tested to
allow for the school to take back the space. However the
sprinkler riser room is on the far side of the building with Phases
4 and 5 in between that won’t be worked on until 2020. Is it the
expected plan that the sprinkler system will be tested but not
live in the earlier phases of the project or are their plans for
temporary removal of ceilings to create access from the
sprinkler riser room to the second floor during phase 2 to allow
the system to be live at the completion of phase 2. (There were
no plans in the phasing to include the ceiling removal work.)
Since there are currently no sprinklers in the building, will the
Fire Marshall allow occupancy in areas with inactive sprinklers?
The Fire Marshall and the Building Official will
require that as sections are turned over that
the fire sprinkler systems be activated in those
areas. This is based on the Ct Fire & Building
codes that stipulate fire sprinklers in "E" use
buildings, as they will fall under the CT Fire &
Building Codes for alterations and new
construction/renovations.

drilling of existing walls will be permitted.” I would imagine there
will be a fair amount of instances where we will need to
penetrate existing CMU walls with 3” or larger diameter holes to
supply sprinkler piping into classrooms. I believe the reason
behind this requirement is due to the lead paint on the CMU
walls, so I want to know if there is a plan to have another
contractor perform wall drilling for the project as a whole? Or
are other options for getting through existing walls available to
us besides drilling the existing?

intent to provide the shades inside of pockets with closures in
order to protect them from the heating effects of the radiant

it be impossible to attach the front fascia that faces the radiant
panels, the proximity of the radiant panels would probably void
