Q10. Regarding Special Specification 606.3042xx25, the specification states that a PE stamped
design shall be provided for the traffic barrier wall. There are (4) barrier items under this
spec. We need clarification on how to interpret this spec. as it pertains to each barrier item.
The first Item 606.30420125 is a standard single slope full (8” top) barrier per NYSDOT
std. sheet 606-14, no special detail is provided, so, no PE design should be required, please
confirm that this is true.
A10. Correct, this is true.
Q11. The second Item 606.30420525 is a standard single slope half sect. barrier per NYSDOT
std. sheet 606-13, no special detail is provided, so, no PE design should be required, please
confirm that this is true.
A11. Correct, this is true.
Q12. The third Item 606.30420725 is a single slope asymmetrical full (12” top) barrier for
pavement deltas from 0” to 12” with a detail/design given on drawing # GRD-8 which
shows no footer or moment slab required for this barrier. Since there is a design for this
barrier provided on drawing # GRD-8, we are interpreting this to mean that no PE design
will be required, please confirm that this is true.
A12. Correct, this is true.

QUESTIONS AND ANSWERS
March 9, 2018 …continued
Q13. The fourth Item 606.30420825 is a single slope asymmetrical full (12” top) barrier wall w/
footer for pavement deltas over 12” with a general detail given on drawing # GRD-8 which
shows a footer but does not show complete design details. Since this is the only item called
out in the quantity estimate as a barrier wall, we are interpreting this as the only barrier
item of the (4) mentioned here that requires a PE stamped design per the above spec.,
please confirm that this is true.
A13. Correct, this is true. Therefore, it is correct that as outlined throughout Questions 10
through 13, that the only barrier item of the (4) barrier items mentioned above, a PE
stamped design will be required only for barrier Item 606.30420825.

Q14. 8 weeks has been provided for the preparation of this bid proposal. This project includes
over 400 bid items as well as a significant technical proposal. Due to various competing
bids that have been advertised in this locality since the beginning of the year, the March
28th bid deadline is an aggressive completion date.
A14. The normal advertising period for a project of this size is 6 weeks. Per the request of the
AGC, two additional weeks have been provided for Best Value Submission. Therefore, a
time extension will not be issued for this project.
Q15. After reviewing all the bid documents up to Addendum #1 for the Contract TANE 18-7
D214568 – Reconstructing a Portion of the New England Thruway (I-95) from MP NE
14.1 to NE 15.0 Including the Replacement of 2 Bridges and the Rehabilitation of 4
Bridges, we request a postponement of the bid due date. The postponement will be
beneficial because we need the extra time to be most competitive and thoroughly analyze,
appropriately price and schedule the complex logistics of building this project while
minimizing the affects to the daily operations of the traveling public.
A15. Please refer to the answer provided for Question 14 (A14.).

QUESTIONS AND ANSWERS
March 13, 2018
Q16. On page 229 of noise barrier spec. above, under (A. Fabrication), it states that noise wall
panels shall be full height with no horizontal joints. This contradicts the plan drawings
#NBD-2 & #NBD-4 which both show a horizontal joint in the panel, stacked panels. There
are a lot of panels at 12’ height & a lesser quantity at 20’ height, with some in between.
With these heights it seems that a full height panel would be preferred because the joint
detail on drawing #NBD-2 shows a minimum top panel height of 10’, which would make
for a 2’ bottom panel in the case of the 12’ height wall. Please confirm what the intent is
here.
A16. Per the plans, horizontal joints will be allowed. The 10' min shown on Section A-A of
Drawing Number NBD-2, sheet 575 of 950 will be deleted by Amendment. Also, a note
stating that the horizontal joint location will be determined by the Contractor and approved
by the Engineer and that only one joint per panel section will be allowed, will be added by
Amendment.
Q17. The typical wall elevation detail on drawing #NBD-2 shows that the post caps are set
above the panel caps & the ends of the panel caps butt up to the edge of posts. If this is the
intended detail, then the top of post elevation should be approx. 6” above the top of panel
elevation. If the 6” overhang is correct, then many of the post heights given in the wall
tables on drawing #NS-1 thru #NS-4 are incorrect. After reviewing the overall post heights
in these tables, it seems that a lot of the heights are incorrect, even without taking into
account the post overhang. Please confirm what the required post overhang should be.
A17. The heights given in the table indicate heights to get to the top of the panel, as shown on
the wall profiles. An extra 6" will be required to get above the panel caps. A note will be
added by Amendment stating that actual post height shall be detailed in the shop drawings.
Q18. In follow up to the Thruway’s response to our RFI-2, regarding stacked noise wall panels
or not, will full height panels be allowed for any of the main panel height groupings (12’ or
20’)? We have the capability of producing all the noise wall panels at the full height
shown, please confirm if this will be allowed.
A18. Full height panels will be allowed for all post and panel walls.

Q19. Drawing SRB-33 shows Fill Type Retaining Wall (Item 554.43) starting right after the new
concrete wing wall on the east side of new begin abutment of the Ramp B Bridge.
Drawing SRB-31 shows new 30'x40' GRES wall (Item 554.3001) being constructed behind
the Ramp B Bridge Begin Abutment extending past the CIP wing walls. We have the
following questions regarding these details:
1- Please address the conflicts between Geo-synthetic Reinforced Earth System (GRES
Wall - Item 554.3001) and Fill Type Retaining Wall which will be constructed adjacent
to the new CIP wing walls (Item 554.43)
2- Contract Bid Item 554.3005 appears to be the correct pay item for this GRES Wall, as
the quantity as shown on SRB-31 of 1,200 SF matches the pay item quantity.
However, the work is called out several times as bid Item 554.3001 on the Contract
Drawings (SRB-31, SRB-12), please clarify correct bid item and adjust quantities, if
necessary.
3- Please clarify the purpose of constructing the GRES Wall at this location.
A19. 1. The contractor is responsible for developing the construction method for integrating the
two systems.
2. Item 554.3001 is the correct item for the GRES wall. Item 554.3005 will be deleted
from the Itemized Proposal. The quantity for Item 554.3001 will be increased from 942 SF
to 2,142 SF.
3. The purpose of the GRES wall is to reduce lateral pressure on the backwall.
Q20. In the Volume 1 Contract Drawings provided, it appears Drawing GRP1 was mistakenly
inserted between PRO36 (Sheet 125) and PRO38 (Sheet 127). The two GRP1 drawings
provided are different, specifying different items for the guardrail end piece on the shoulder
of Northbound I95 @ approximately mile point N563+00. Should this item be
606.34030025 or 606.27? Also, please clarify if PRO37 is missing from contact
documents.
A20. An Amendment will be issued to delete duplicate Drawing Number GRP-1, sheet 128 of
950 and replacing it with the correct Drawing Number PRO-37, sheet 126-A2 of 950. On
Drawing Number GRP-1, sheet 128 of 950, reference to Item 606.34030025 is to be
replaced with Item 606.27. Also, be advised of a Special Note on Proposal page 393
regarding Item 606.27.

QUESTIONS AND ANSWERS
March 13, 2018 …continued
Q21. Contract drawing SPD-4 provides the details for the Fiber Optic Pullbox as part of the ITS
system. The detail provided shows that this pullbox must be installed at 12' minimum
offset from the pavement shoulder. However, on the plan drawings, these pull boxes are
shown within this required offset and there is not sufficient space to provide the required
12 feet.
A21. An Amendment will be issued to delete reference to the "12' minimum offset" from the
fiber optic pull box detail. The following note will be added in its place: "See ITS Plans
for offset location".
March 14, 2018
Q22. In the Supplemental Information quantity calculations, Item 206.01 Structural Excavation
has a quantity of 4 CY. In the estimate of quantities in the proposal book, Item 206.01
Structural Excavation has a quantity of 6,626 CY. Please clarify.
A22. The total volume for Item 206.01, Structure Excavation is 6,626 CY. Please refer to pages
763-772 for the Ramp B Bridge (1,900 CY) and pages 786-787 for the Grace Church Street
Bridge (4,722 CY) of the Supplemental Information quantity calculations.
Q23. On Contract Drawing EES-1, Earth Summary Sheet, there is no table for Item 206.01,
Structural Excavation. Can a table be provided listing the quantity of rock and non-rock
and the source location based on the 6,626 CY quantity for Item 206.01 in the proposal?
Note: A table was provided for Item 206.0201, Trench and Culvert Excavation.
A23. We did not break out the rock vs. non-rock excavation for Item 206.01, Structure
Excavation in our estimate so we cannot provide that information at this time.
Q24. Contract Specification 643.9201—25 – “Installing Foundations for Noise Barriers”, Basis
of Payment states that the unit price for this pay item includes placing concrete and
reinforcing. Contract Specification 643.99010004 – “Precast Concrete Noise Barrier
System”, Basis of Payment states that unit price for this pay item includes concrete
foundation and reinforcement. Which pay item will the concrete and reinforcement for the
noise barrier wall foundations be paid under?
A24. As per Note 6 of General Noise Barrier Wall Note on Drawing Number NBD-1 (sheet 574
of 950), the concrete foundation will be paid for under Item 643.9201--25, Installing
Foundations for Noise Barriers or Wood Screen Fencing.

QUESTIONS AND ANSWERS
March 14, 2018 …continued
Q25. Contract Specification 643.9201—25 – “Installing Foundations for Noise Barriers”, Basis
of Payment Section states that the unit price shall include the cost of drilling through all in-
situ soils and bedrock. Contract Documents provide various boring logs that were taken
along the proposed noise walls. However, the boring logs provide insufficient information
to accurately determine the rock elevation along the noise barrier wall locations. For
example, the boring logs that were taken along the proposed “Visual Barrier N1” locations
are at distances of 200 feet to 400 feet apart, no borings were taken at “Noise Barrier N3”,
some borings at Noise Barrier S1 have distances of 200 feet apart, and borings at Noise
Barrier S2 have a distance of 200 feet to 400 feet apart.
Contract Item 643.9201—25 includes both soil and bedrock drilling and is paid by the
lineal foot of foundation installed. Since rock elevations will be difficult to determine
based on the limited boring information provided in the Contract Documents, will the
Authority consider creating a separate pay item for installation foundations in rock for the
noise barrier?
A25. Item 643.9201--25, Installing Foundations for Noise Barriers or Wood Screen Fencing
covers installation of foundation in both soil and bedrock. A separate pay item for
installation foundation in rock for the noise barrier will not be included.
Q26. Contract Drawing Nos. NB-4 through NB-15 show an approximate rock location for the
proposed noise barrier wall locations. The quantity of rock sockets foundations to be
performed under pay Item 643.9201—25 will be determined based on the actual rock
elevations encountered. Contract Drawing No. NB-8 shows an approximate rock location
for Noise Barrier Wall N3. No borings have been provided along this noise wall. Is the
Contractor to assume that the approximate rock line show is accurate for this location?
A26. The approximate rock line is based on past record plans and the geotechnical report. The
Contractor shall assume that the approximate rock line is accurate for bidding purposes.

Q27. Contract Drawing Nos. WAL-1 through WAL-9 show the plan and elevation of the
proposed Retaining Walls #2 and #3. These drawings show a typical panel spacing
between soldier piles at 8’-0”. Contract Drawings Nos. WAL-16 through WAL-20 provide
tables for the same retaining walls which show the panels at various widths. Is the typical
8’-0” spacing shown on Drawings WAL-1 through WAL-9 correct? What is the horizontal
pay limits of the precast concrete lagging panels, Item Numbers 552.230301 and
552.230302? Is the horizontal pay limit the actual width of the panel or is the horizontal
pay limit from center line of soldier pile to center line of soldier pile?
A27. The 8’-0” spacing shown on Drawing Numbers WAL-1 thru WAL-9 (sheets 322 to 330 of
950) represents the center-to-center spacing of the piles. The horizontal pay limit for the
panels is based on the width shown in the tables and on Drawing Numbers WAL-16 thru
WAL-20, sheets 337 to 341 of 950.
Q28. Contract Drawing Nos. SRB-47 and SRB-48 provide details for Retaining Wall No. 4.
Contract Drawing No. SRB-48, “Typical Cantilever Soldier Pile and Lagging Wall
Retaining Wall No. 4” shows drilling a rock socket from existing rock surface down to the
tip of the soldier pile. However, the finished grade at the front of the retaining wall is a
distance below the existing rock surface. How is the Contractor to install the precast panels
below the existing rock surface without excavating the rock down to the bottom of the
proposed precast panels? Shouldn’t the detail for Retaining Wall No. 4 be similar to the
detail for Retaining Wall No. 3 shown on Contract Drawing No. WAL-13 for Sta. W3
0+00 to Sta. W3 1+62.6, which shows a vertical rock excavation pay limit behind the wall
from existing rock surface down to bottom of proposed precast panel? If so, then the
minimum rock socket quantity shown in the Retaining Wall 4 Pile Schedule on Drawing
No. SRB-48 would be overstated. Please advise.
A28. A revised Drawing Number SRB-48 (sheet 445-A2 of 950) which shows the new wall pay
lines and a revised pile table will be issued by Amendment.
Q29. Contract Drawing No. SRB-12, Section A-A “Proposed Begin Abutment” shows a bold
dotted line around the excavation required for the proposed Begin Abutment Stem. The
legend on this drawing states that the areas enclosed within this bold dotted line is paid
under Item 206.01. However, Section A-A also calls out a vertical pay limit dimension for
unclassified excavation Item 203.02. Please clarify the pay limits of both Item numbers
203.02 and 206.01 for the Proposed Begin Abutment shown in Section A-A.
A29. Excavation shall be paid for under Item 206.01, Structure Excavation per the legend. A
revised drawing removing the vertical pay item pay limit dimension for Unclassified
Excavation, Item 203.02 will be issued by Amendment.

Q30. Contract Drawing Nos. EQ-1, SRB-9, and SRB-31 all call out Item 554.3001 –
Geosynthetic Reinforced Earth System Wall – Welded Wire Forms to be utilized for the
Begin Abutment. However, Drawing No. SRB-28 “Typical Begin Abutment Section” calls
out Item 554.3005 behind the abutment. The “Wall Facing Detail” shown on Drawing
SRB-31 shows no welded wire forms for this wall. Should the pay item for Geosynthetic
Reinforced Earth System utilized for the Ramp B Begin Abutment be Item 554.3005
instead of Item 554.3001 since no weld wire forms are required for this location?
A30. The GRES wall for Ramp B shall be paid for under Item 554.3001, Geosynthetic
Reinforced Earth System Wall Welded Wire Forms. For details of the welded wire form
refer to Standard Sheet 554.02, sheet 5 of 6, details D and F.

shall be performed within the environmentally sensitive area without the monitoring
archeologist on site.” Will the New York State Thruway Authority provide and pay for the
Monitoring Archeologist? If the Archeologist is to be provided by the Contractor will a bid
item be added to the Contract for this work required?
A31. Note 2 will be revised to state the following “No work will be allowed within the
environmentally sensitive area.”
Q32. Can the Asbestos Assessment Report be made available to the bidding Contractors?
A32. The Asbestos Assessment Report will be provided as Supplemental Information.

Q38. Plan sheet 575, NBD-2 the upper left detail for Typical Wall Elevation has for payment
item 607.99620010 for vertical measurement and item 643.99010004 for horizontal
payment. Please confirm that the vertical measurement should read 643.99010004?
A38. Correct, the vertical measurement should read as “FOR PAYMENT LIMIT
643.99010004”. Revision will be included in Amendment 3.
Q39. Plan sheet 46, MST-9 the lower right table for Noise Barrier has the pay items
607.92030025 and 607.99620010.
a. Please confirm that these should read 643.920125 and 643.99010004, respectively
b. Also, in the same table, lower lines also use the item 607’s.
c. In the lower lines for the foundations it indicates (3’-6” diameter) when all other tables
and plans indicate a 3”-0” diameter foundations. Please confirm that the foundations are
per the Noises Barrier Schedule 1 – 4. (pages 594 – 597).
A39. The Table of Noise Barriers found on Drawing Number MST-9 (sheet 46 of 950) will be
deleted. Refer to Noise Barrier General Plan and Elevation on Drawing Numbers NB1

will be included in Amendment 3.
Q40. Contract Drawing SRB-12 calls for Contract Bid Item 207.300125 – Synthetic
Compressible Inclusion behind the proposed abutment stem. The call out on this sheet says
“12”, Synthetic Compressible Inclusion”. However, Contract Specification 207.300125,
Material section, calls for the panels to be 4 ft. x4 ft. x 10 inches thick. Please clarify the
thickness required for this material.
A40. The required thickness is 12". The specification calls for 4 ft. x 4 ft. x 10 inches thick or
thickness as shown on the plans.
Q41. We have not been able to locate Contract Item 203.17130017 – Resin Rock Bolts 1”
(Grade 150) on the Contract Drawings. Also, no calculations have been provided in the
Engineer’s quantity work up sheets.
A41. The rock bolt item is included in the contract on a contingency basis. Following presplit
blasting of the rockslopes, there may be a joint or weak rock layer that would leave an
unstable rock face above. It may not be possible (due to ROW or quantities) to scale this
rock behind the presplit line. Rock bolts may be required to stabilize this rock.

Q45. On Dwg. No. GRD-9 for the custom transition barrier and on Dwg. No. GRD-10, General
Notes, it indicates that the Item No. 606.30330008, Concrete Barrier (modified) comes
from NH DOT and is for precast concrete barrier. The Quantity Sheet Summary for
Proposal on Page 28 does not indicate if this custom 54” high barrier is CIP concrete (as
shown on GRD-10) or precast concrete. Please verify if Bid Item No. 606.30330008 is to
be CIP or Precast concrete barrier. If precast, then is the detailing, rebar, dimensions and
connection methods shown on GRD-9 and GRD-10 sufficient to meet all of the contract
requirements indicated in General Notes 4 and 5? It is not customary or typical for a
precast manufacturer to be responsible for a crash test of barrier that meets or exceeds
NCHRP Report 350 for test MASH TL-5. The dynamic crash test is “very expensive and
has a very significant lead-time” and performed at only two nationwide independent testing
facilities. Is the dynamic crash test required for this custom 54” barrier or is a theoretical
MASH TL-5 engineering design analysis only acceptable? Does NYS Education Law
Section 145 allow a precast manufacturer the ability to provide a NYSPE stamped design
for this custom barrier? Please verify and confirm all.
A45. Item 606.30330008, Concrete Median Barrier (Modified) is to be pre-cast. Crash testing of
this concrete median barrier (modified) will not be required. A stamp from a New York
State Professional Engineer is not required. Since NYSDOT does not have a Standard
Sheet for 54” concrete barrier, the New Hampshire DOT standard sheets were used to
develop these details. Note 5 will be deleted and Note 6 will be revised to read as follows:
“Details shown are based on the New Hampshire Department of Transportation’s 54”
Single Slope concrete barrier, single faced, precast standard detail. The details are in
compliance with requirements per updated NCHRP Report 350 for test No. 5-11 (MASH
TL-5). Documentation is included in the FHWA Acceptance Letter B64”. Revision will
be made in Amendment 3.

Q46. On Dwg. No. LTN-2, a Lighting Standard Schedule indicates the foundation requirements
for the lamppost. The detail for the barrier lamp post foundation is shown on DWG. No.
LTD-3 (Sheet 315) and includes the casting in cast iron junction boxes and anchor bolts
and conduit. The first four (4) Pole No.’s listed on LTN-2 (i.e. 1 thru4) appear to be located
on existing concrete median barrier. Pole No. 5 is the first lamp post that could be “cast
into” the “new” precast concrete barrier. Please verify and confirm that only Pole No’s 5
thru 20 and 53 will be cast into the “new” precast concrete barrier on this project. Where
specifically (dimensionally and in elevation view) is the cast iron junction boxes that are to
be cast into the face of precast barrier sections relative to the lamp post anchor bolts,
conduit and 90 degree sweep that are cast in? Also, how is the Barrier Lamp Post
Foundation detail on LTD-3 work for a lamp post that has cast in items on what appears to
be existing median barrier? Please confirm.
A46. The first four (4) Poles (1 thru 4) are on existing barrier. The intent of the design was that
in these sections of the existing concrete barrier, the contractor would remove the existing
section of barrier and replace the barrier with a new barrier that would accommodate the
light pole attachment and conduit. The barrier would have to be wider in the center (to
accommodate the 12” needed for the light pole base plate) and then transition into the
thinner barrier to tie into the existing surrounding barrier. Please refer to NYSDOT
Standard Sheet Drawing 670-02 for additional details on symmetrical concrete barrier lamp
post foundation. Pole No’s 5 thru 20 and 52 can be cast in place or precast with the light
pole attachment, conduit and junction box in the concrete barrier section. The barrier
mounted cast iron junction boxes shall be placed 5’ from the center of the light pole to the
center of the junction box and 18” from the center of the box to finished grade.
Q47. On Dwg. No. Wal-15 (Sheet 336) under Soldier Pile and Lagging Wall Note 9, the exposed
wall panel surfaces are to have a front traffic side (#129A or equal) and back residential
side (#182 or equal) formliner finish. Please confirm that any buried portions of the precast
lagging wall panels will NOT require a grape stake formliner finish on the “non-exposed
and buried” residential surface as indicated in the elevation views with finished grades
behind the walls as shown on Dwgs Wal-1 thru Wal-14.
A47. Per Note 9 on Drawing Number WAL-15 (sheet 336 of 950), architectural pattern shall be
utilized to a minimum of 2’ below final grade.
Q48. Please confirm all precast concrete Noise Barrier is to be reflective noise barrier and not
absorptive noise barrier.
A48. All precast noise barrier is to be reflective.

Q49. On Dwg. No. SRB-33, SRB-34 and SRB-41 Notes 5 and 6 and on SRB-43 thru SRB-45
Note 5 indicate the new fill type retaining walls are to “match” the noise walls installed
under contract TANE 03-06. Please provide the manufacturer’s name and year the noise
wall panels were built and installed. There is no way given the environmental conditions
and lapse of time from manufacturing the noise wall panels and the new precast wall units,
they will not match in color. If the Federal ID # 12300 is the standard, then please confirm
the new fill type retaining walls on this project should be as close as possible to a match of
that federal standard color # 12300.
A49. The intent is to match the color, as close as possible, of the existing Noise Barrier located
within the project limits between MP NE 13.47 to NE 14.78. A color sample panel from
the precast plant shall be provided to the EIC for approval. Reference to the federal
standard color #12300 will be deleted. Revision will be made in Amendment 3.
Q50. Per Specification for Item 643.99010004 – Precast Concrete Noise Barrier System on Page
230, Design and Shop Drawings, it indicates that the contractor shall design the precast
noise barrier system. On Dwg. No. NBD-3 (Sheet 576), it appears to have an already
designed precast concrete post size, keyways and reinforcing. Does this design and
detailing meet the requirement for a contractor designed noise barrier wall system and can
the dimensions and rebar layout be utilized for this project? Please confirm the precast
posts dimensions and rebar layout, the precast wall panel thickness shown on Dwg. No.
NBD-2 Section A-A and the precast cap dimensions on Dwg. No. NBD-4 are acceptable
and meet the design criteria as shown.
A50. The Contractor shall design the precast noise barrier system per the specification. The caps
for the posts and panels are being removed from the contract, new drawings were issued in
Amendment 2.

Q51. Per Specification 606.3042XX25 – Single Slope Traffic Barrier, under Part 1.02 it
indicates that the Concrete Traffic Barrier (Wall), Item No. 606.30420825 “shall be
designed” by a NYSPE. This precast barrier is indicated on Dwg No. TYP-3, Detail M2
and M3 and Dwg. No. GRD-8. This precast barrier wall (I.e. Vari-Wal) was developed
between Fort Miller and the NYSTA many years ago and has been installed on many
NYSTA mainline projects over the past 30 years. More recently on NYS Thruway I-90
between Exit 23 and 24 by Rifenburg Construction, Union Concrete (for NYSDOT on
D262652) in the Buffalo area, etc. and many other NYSTA projects. Will this precast
barrier wall called Vari-Wall meet the spec requirements and be accepted on this project
too per all of our previous barrier dimensions, reinforcing and connection details? What is
the min and max roadway differential that requires the use of the Traffic Barrier Wall
Item? Per GRD-8, it appears that the Asymmetric barrier is only allowed from 0” to 14”
max Delta (i.e. roadway differential). In the past, asymmetric barrier was acceptable with a
Delta between 0” to 21”. In the past the Vari-Wall has been acceptable for Deltas from 21”
to 48”. Is the Vari-Wall barrier system still allowed on this project from Deltas from 14” to
48” ? What precast barrier and Item No. is to be used with Deltas from 14” to 21” ? Please
confirm all.
A51. Per the plans and specifications, a concrete traffic barrier (wall) design by a PE will be
required for differentials greater than 12”. Asymmetrical barrier, as shown on GRD-8, will
be allowed for differential up to 12”.
Q52. Please confirm the Federal Fan Deck color for fill type retaining walls, precast lagging
walls and noise barrier wall panels and posts as identified in the contract plans is correct
and to be color #12300 and “orange”.
A52. Please see the response to Question 49 (A49.).

Q53. Per Dwg. No. Wal-15 (Sheet 336 of 950), the precast lagging wall panels are shown as 5’-
0” high. On the Retaining Wall Plan and Elevation views on Dwg. No’s Wal-1 thru Wal-
10, it appears the precast lagging panels are depicted as “one piece” with no horizontal
joints. Given the individual panel retaining wall heights between pile for the various
retaining walls in the Pile Schedule tables on Dwg. No. Wal-16 thru Wal-21, 1.) are the
precast lagging panels to be 5’-0” high or full height? 2.) If the precast lagging panels are
to be a maximum and typical of 5’-0”, then what is the “minimum” precast lagging wall
panel height, 3.) what is the joint configuration and joint material between precast lagging
panels and 4.) what is the reinforcing layout that is to be used to make up the possible
“shorter” varying precast lagging wall Panel heights?
A53. 1.) Horizontal joints were not shown on the plans. Precast lagging panels shall be 5’-0”
high.
2.) Minimum panel height shall be 2’-0”
3.) See joint detail on revised Drawing Number WAL-15 (sheet 336 of 950)
4.) Reinforcing for smaller panels shall be the same as the reinforcing for the 5’-0” panel.
Horizontal bars: #5’s @ 6” o.c. Each Face, Vertical Bars: #5’s @ 24” o.c.
Revised Drawing Number WAL-15 (sheet 336 of 950), will be issued under Amendment 3.
Q54. Also for consideration; steel pier cap girders and transverse girders at piers 1 and 2 should
normally require “Full Component Assembly” in accordance with NYSCM Section
1103.4.1. Question: Can Section 1103.4.5 Special Complete Structure Assembly (Sheet
396, GN-1, General Notes #12) be excluded?
A54. Section 1103.4.5 cannot be excluded. As per general Note #12 on drawing GN-1 – the
structure shall be assembled per section 1103.4.5.
Q55. Per Dwg No. GRD-8, the Asymmetric barrier Item No. 606.3042075 indicate a roadway
elevation difference (Delta) of 0” to 14” at the top and 0” to 12” at the bottom. Shouldn’t
the limits be the same limits? What is correct and maximum Delta that can be used for
this Bid Item? Please verify. Is the 18” of embedment below finished grade correct? It
typically is a 9” embedment. Please confirm.
A55. Drawing GRD-8, sheet 153 of 950 will be superseded in forthcoming Amendment 3. The
0-12” (delta) shown at the bottom is correct. An 18” embedment is required.

Q56. For Visual Barrier N1 Plan Views shown on Dwg No’s NB-1 thru NB-15 and schedules in
NS-1thru NS, there appears to be a conflict with the depicted post layout and stationing as
listed in NS-1 thru NS-4. For example post NB1-50 on Dwg. No. NS-1 says the post is at
station 15+56, however if you count 50 posts starting w/ post NB1-1 in the Plan View on
Dwg. No. NB-1, the 50th NB1 post ends up on Dwg. No. NB-2 Plan View and around
station 14+00? Please clarify what is correct (Plan views or NB1 Schedule and stations).
The post numbering and spacing shown on NB-1 thru NB-4 and stations and posts spacing
in Dwgs NS-1 thru NS-4 appear to be in conflict and not matching.
A56. The line depicting the noise/visual barriers is not an actual representation of the post
layout. The noise barrier schedules on Drawing Numbers NS-1 to NS-4, sheets 594 to 597
of 950, should be the determination of the post location.
Q57. General Plans GNP-4 through GNP-6 show existing noise barrier being removed under
item 203.02 - Unclassified Excavation and Disposal. Please provide removal limits in
station and elevation including any foundation removal. Please confirm the payment item is
correct and what unit of measure will be used.
A57. Limits of noise barrier removal is to coincide with the limits of proposed new noise barrier
in these areas and to include all portions of the existing barrier (ie, panels, wall posts, post
caps and foundations). Removal is to be included in the costs for Item 203.02, Unclassified
Excavation and Disposal. On Drawing Numbers GNP4 & GNP-5, sheets 77 and 78 of 950,
respectively, Limits = B 28+16.86 to B 30+14.72. On Drawing Number GNP-6, sheet 79
of 950, Limits = N 586+00.00 to N 587+94.74.
Q58. See Drawing Sheet 608/950, Note no. 55. The note requires the contractor to replace the
existing utility covers with reinforced covers in the shoulders that are impacted by the
WZTC traffic patterns under the Lump Sum MPT Item 619.01. We request a detail be
provided in an amendment of the reinforced utility covers that will be accepted by the
Thruway Authority for this requirement. What is the quantity and type of covers that will
need to be replaced?
A58. Note 55 on Drawing Number WZN-002, sheet 608 of 950, will be deleted by amendment.
Under Item 619.01, it is the responsibility of the Contractor to make sure that all grates and
manhole covers are secure to permit the safe, comfortable passage of vehicles at the posted
speed limit.

Q59. Drawing SRB-68 shows the elevation detail of Fascia Girders (G1 &G6) along the
centerline but there is no given similar elevation details for the intermediate Girders.
A59. Please refer to the Table of Plate Dimensions and notes 9 & 10 on Drawing Number SRB-
68 (sheet 465 of 950), which presents the required information to produce fabrication
drawings for the interior girders.
Q60. Reference: RAMP B - Sheet 396, GN-1, General Notes #12, - Sheet 397, GN-2, General
Notes #19, and #20. B. Considering: Where a no load condition is required until steel is
erected, shop assembling crossframes will need to be fit in a forced condition due to
detailing for rotation based on a “Steel Dead Load”. Shop assembly based on these
conditions may be unsafe and field fit of the assembly cannot be guaranteed.
A60. It is standard practice in New York State to fabricate the diaphragms so they will fit in the
superstructure with the girders fully deflected for dead load.
Q61. For Bid Item No’s 606.30420725 and 606.30420825 shown on Dwg. No. GRD-8, there is a
roadway elevation difference (Delta). Hence, that is why these types of asymmetric precast
barrier and bid Items are required and utilized. To prepare a bid estimate and cost for these
two (2) barrier items, the F.G elevations at both faces of barrier between roadways MUST
be given and at least at every 50 to 100 Lf and shown in some format on the contract plans
in order to determine a responsible scope and pricing for these two (2) bid items. All
previous NYSTA projects have supplied this roadway elevation information and stationing
in a table format. Please provide the information and where we can find the roadway
elevations at the face of barrier/roadway and finished grade by station as it relates to the
precast barrier layouts and limits as shown on Dwg. No’s GRP-1 to GRP-8.

Q62. Dwg. No. PSL-001 thru PSL-005 show the precast concrete pavement slabs with a typical
length of 15’-6”. Most of the lanes are 12’ wide, but some of the lanes vary from 14’ up to
as much as 22’ wide. Because the slabs are reinforced, we can build and install the slabs,
but transporting these very wide and heavy slabs will require expensive pilot cars and many
significant travel restrictions. In the pavement areas requiring 14’ wide or greater precast
slabs (which is everywhere the precast is required), can the length of the slab be shortened
to 11’-4” or less so that the slabs can be shipped as permitted loads (11’-4” long + 7”
protruding dowels or 11’-11” shipping width)? If it is required by the engineer that the
transverse joints all line up across the road, then the adjacent cast-in-place slabs would also
have to be shortened accordingly. Please verify and confirm.
A62. The pavement slab layout plan shown on the plans was designed to utilize the current
NYSDOT standard slab sizes of 15’-6” slab lengths with 12’ travel lanes and 14’ right edge
lanes. Non-standard slabs were used only in ramp/roadway transition areas as needed. The
Authority will allow reduced transverse joint spacing in pavement areas requiring 14’ wide
or greater precast slabs for the purpose of allowing the slabs to be shipped as permitted
loads as long as the PCC slab aspect ratio and geometry are met per NYSDOT Standard

Q65. We have a few questions regarding the construction schedule to be provided with our
proposal, per part 3.2 of the Best Value Selection Scoring.
A) The Gantt Chart provided in the excel format, and in the example included in the
proposal documents contains columns or cells representing 12 months with a certain
amount of rows for the work activities and Gantt chart bars, is the proposer at liberty to add
columns and rows to the Gantt chart, and expand this chart and sections below as needed?
B) Is the large scale plot of the Gantt Chart in a pocket or sheet protector the only
construction schedule to be included with our technical submission, or is the schedule to be
presented in another form as well as the large scale plot?
C) What is the sheet size or maximum size of the sheet for the large scale plot? And is
“Times New Roman” font 10 the minimum font for this plot?
D) Because this is a complex project with multiple stages and with much information
requested to be provided with the submission, multiple sheets may be needed to clearly
present our schedule, and approach to the work, are there sheet limits with regards to the
schedule?
E) With regard to the crew makeup section below the Gantt chart, are we to provide the
crew makeup of each activity included in the Gantt chart, or is the example of one crew for
a particular task sufficient? Say a forming crew is comprised of this ….. a steel erection
crew this ….., road excavation crew this?
F) Equipment to be included in the “Equipment” column is just major equipment? Is the
general description of the equipment enough, say a backhoe versus rubber tire backhoe, or
Caterpillar 320, or crane versus 180 ton crane or 35 ton cherry picker?
G) As some activities in the schedule may be performed both at night and during the day,
are we to provide separate activities for day and night, or is “day and night work” sufficient
as an explanation for those activities in which this situation occurs?
H) It is also noted in this section, that we are to update this schedule on a bi-weekly basis
following project award. Would this be in addition to the CPM Progress Schedule being
paid for under section 639.2x010011? Are we to include in our price the cost to maintain
two schedules? If so, where are we to include the cost of maintaining this schedule?
A65.
A) Yes, but only to provide information requested for the Best Value Submission.
B) Per Section 3.2 of the Best Value Submission requirements, the Gantt Chart is the only
construction schedule to be included with the Best Value Submission.

A65. C) There is no requirement for the sheet size as long as it can be reasonably inserted in a
pocket or sheet protector. Per 1.1 General Requirements, Times New Roman 10 font is the
minimum font size for the plot.
D) No, there are no sheet limitations with regards to the Gantt Chart.
E) A description of one crew for a particular activity may be sufficient to describe the
same crew for other activities as long as the same crew make up applies to the other
activities. Any changes to crew make up must be noted, including day and nighttime crew
composition for same activity.
F) General description of the equipment is enough.
G) The same work activity may be noted as day and night work, but it is a requirement that
the time duration of day and night work be defined for the activity.
H) The Gantt chart prepared for the Best Value Submission will not be required to be
updated on a bi-weekly basis. This requirement will be deleted by amendment from
Section 3.2 of the Best Value Special note.

Q68. Per Q & A #13 and #51 and the Note under Item No. 606.30420825 on Dwg. No. GRD-8
(Sheet 151/950), the precast concrete traffic barrier wall is to be designed by a NYSPE.
Please clarify and provide the specific limits to be used in the varying barrier height (i.e.
min. and max Delta (differential) between pavements at face of barrier), the design loads,
criteria and standards that are required to be used and confirm a dynamic crash test or static
load test will NOT be required for this precast barrier wall and the NYSPE stamped barrier
wall design will suffice and meet all of the contractual requirements for this Item on this
project.
A68. A spreadsheet with differential at face of barrier has been provided as supplemental
information (Amendment 3). The barrier is to be designed per Section 13 of AASHTO
LRFD Bridge Design Specifications for Test Level (TL) 4. A dynamic crash test or static
load test will NOT be required for this precast barrier wall. A NYSPE stamped barrier will
suffice and meet all the contractual requirements for this item on this project. (Revised on
March 30, 2018; Changed (TL) 5 to (TL) 4)
Q69. We also respectively request a one week bid postponement to 4/18/18 given the complexity
of the job and all of the Q&As and Amendment #3 have yet to be received.
A69. The letting date has already been postponed once. A six week advertisement period is
typical for a project of this size. As recommend by the AGC, two additional weeks were
provided for preparation of the best value submission. An additional two weeks was then
provided as requested by plan buyers. Therefore, a total of ten weeks has been provided
for bid preparation and best value submission.
Q70. Can alternate designs be allowed for the temporary soldier pile and lagging walls? I.E. can
a "Contractor Designed" temporary SOE bid item be utilized as opposed to the "Design
Provided" bid items listed?
A70. Alternate design will be may be allowed for the temporary soldier and lagging walls as
long as the alternate design complies with New York State DOT Standard Specifications
and design guides including, but not limited, to Chapter 4 of the Bridge Manual. The
Shields and Shoring item will not be considered an acceptable alternate design. Alternate
design must be designed and stamped by a New York State Professional Engineer.
Q71. For S1 noise barrier locations from STA 10+50 to 14+57, the existing grade is below the
proposed bottom of the noise barrier wall because the new retaining wall will be backfilled.
Will the drilled shafts be paid from the bottom of panel to the drilled shaft tip?
A71. The drilled shafts for S-1 shall be paid for from the bottom of the post connection, shown
on NBD-2, for the indicated length shown on the schedule for S-1, similar to that of the
other noise/visual barriers.

Q75. Several critical subcontractors are requesting additional time due to the magnitude and
complex nature of the project. These critical subs will have an impact on defining the
construction schedule which directly effects the preparation of the Best Value Submittal.
The subcontractors include several minority certified firms (MBE&WBE). For this reason
we respectfully request a two week postponement of the current letting date of April 11,
2018.
A75. The letting date has already been postponed once. Six week advertisement period is typical
for a project this size. As recommend by AGC, two additional weeks were provided for
preparation of the best value submission. An additional two weeks were provided as
requested by plan buyers. A total of ten weeks has been provided for bid preparation and
best value submission. No postponement of letting is being considered.
Q76. Contract Drawing SRB-OS1E (Plan Sheet #343), Span Structure Table, shows the substrate
type (soil/rock). Note 10 states that the substrate type shall be designated S (Soil) or R
(Rock) and total shaft length in rock shall be indicated in parenthesis. S.I.N. #1 shows the
following “R 19.7 (4.0)”. According to note #10, this would mean the total shaft length in
rock is 4.0ft? Or is the shaft length in rock 19.7ft?
A76. The total length of shaft is 19.7’. The length of shaft in rock is 4’.

Q77. In response to the NYSTA answer to Question # 30, GRES wall located at Ramp B North
Abutment as shown on plan sheet 428 does not required a welded wire form. It seems that
the designer’s original intent was for this GRES wall to be paid under bid item 554.3005 –
Geosynthetic Reinforced Soil System Wall – Other. However, this item was eliminated in
Amendment #2. Amendment #2 now calls for all GRES walls to be paid under item
554.3001 which includes welded wire forms. Please confirm that welded wire forms will
not be required for the GRES wall shown on Plan Sheet 428.
A77. No- Welded wire forms will be required at Ramp B north abutment
Q78. Contract Proposal page 41-A1 “SCHEDULE AND SUSPENSION OF WORK”, Section
A.1. states that lane closures on the Thruway shall only be allowed in accordance with the
traffic management table(s) available on the Thruway Authority website. NYSTA Lane
Closure Chart TA 619-30 (Sheet 18 of 24) “I-95: INT 21/22 – CT (MP 14.4 – MP 15.0)”
falls within the limits of this project. The chart calls for 3 lanes required to be maintained
Monday through Friday from 6AM to 8PM. However, starting in Stage 4 of the WZTC
Plans, I-95 NB and SB are reduced to 2 lanes utilizing temporary concrete barriers for
establishing work zones. Therefore, the configuration in Stage 4 and subsequent stages of
the project do not comply with the NYSTA Lane Closure Chart between MP 14.4 and MP
15.0.During the multiple stages when I-95 NB & SB will be restricted to 2 travel lanes, will
the Contractor be permitted to reduce traffic to a single lane during the time period when
the chart calls for 2 travel lanes to be maintained? For example, on Monday night the Chart
(Sheet 18 of 24) shows an allowable reduction in travel lanes from 3 lanes to 2 lanes NB
from 8PM to 12AM. Since I-95 is already reduced down to 2 travel
A78. The contractor will not be allowed to reduce traffic to a single lane during the time period
when the charts call for 2 travel lanes to be maintained. Lane closures shall only be
allowed in accordance with the traffic management table(s), unless indicated otherwise in
the contract documents.

QUESTIONS AND ANSWERS
March 30, 2018 …continued
Q79. In response to Amendment #2 3, Plan changes, #15 – Drawing SRB-48 was revised to
depict a rock socket with the top elevation of the rock socket starting at the proposed
bottom of the lagging panels. The previous version of this drawing showed the rock socket
starting from the existing approximate rock surface. However, the Retaining Wall 4 Pile
Schedule (table) on this drawing still shows the same values for the minimum rock socket
as well as the estimated pile tip. Please confirm that this is correct and that the value of
rock socket shown in the schedule is to be drilled from the bottom of panel. For example,
Pile Number 1 has an estimated pile tip of 30ft with an assumed rock elevation of 37ft
which would make the rock socket 7ft. However, the schedule calls for a 20ft minimum
rock socket for Pile Number 1 which would put the pile tip elevation at 17 ft. The 20ft
minimum rock socket seems excessive for this location compared to the design of the
Retaining Walls which only call for a 5 ft minimum rock socket. Please clarify the
minimum rock socket values required for Retaining Wall #4.
A79. The Contractor should adjust the pile tip elevations as required to satisfy the specified
minimum rock socket lengths. Drawing Number SRB-48, will be re-issued in Amendment
#4.
Q80. Per Dwg. No. GRD-8, it indicates that the concrete traffic wall for Item No. 606.30420825
– single slope concrete barrier wall (wide barrier pre-cast or cast-in-place) shall be
designed by a professional engineer licensed in the State of New York. The detail on Dwg.
No. GRD-8 gives fixed dimensions (i.e. 1’ thick x 8’ wide footing, a 1’-4” wide toe, 12”
wide top, 36” buried, etc.) for the barrier unit. Please verify that a global analysis was
performed on the shape and dimensions shown are adequate and that the NYSPE design
required is for structural capacity of the precast traffic wall.
A80. Yes, a global analysis was performed on the shape and dimensions shown are adequate. A
NYSPE design is required is for structural capacity of the precast traffic wall.
Q81. Item 11 in Amendment 3 directs us to remove portions of the existing noise barrier
sections, including foundations. Are the foundation to be completely removed, or removed
to 2'-0" below final grade?
A81. The existing noise barrier foundations can be removed 2'-0" below final grade as long as
there are no conflicts with proposed work.

QUESTIONS AND ANSWERS
April 05, 2018
Q82. Please clarify the detail (precast concrete lagging end treatment/noise barrier panels) that
was added to drawingWAL-15 in addendum 3. Our interpretation is that only the exposed
noise wall panels (new item #552.230305 & #552.230306) on retaining walls #2 & #3 get
the haunched end treatment on the panels & that the below grade retaining wall/lagging
wall panels on these (2) walls as well as Ramp L wall do not require the haunch.
A82. Correct.
Q83. Also the requirement by note #9 on this same drawing, that architectural finish on the
backfilled/rear face of panels shall extend to 2’ below grade, does this apply to lagging wall
areas on these 3 walls that do not have a noise wall panel stacked on top of the lagging
wall/retaining wall.
A83. No. 2’ finish requirement is only for noise wall panels.
Q84. So does the Ramp L wall have this 2’ finish requirement on the rear face & also portions of
retaining wall #2 that do not have a noise wall above, is this 2’ finished area required.
A84. No
Q85. This same question would also apply to the haunched end treatment in these areas that do
not have a noise wall above the retaining wall.
A85. The haunched end treatment is only required for the noise wall portion. Per Note 8 on
WAL-17 (336 A3/950), the contractor can submit alternative methods for holding panel
tight against the pile flange to the Engineer for approval.
April 06, 2018
Q86. On drawing SRB-61 a CJP weld detail is shown for the bottom flanges slope transition.
Would it be acceptable to have those flanges bended?
A86. Bending the bottom flange plates in lieu of welding is acceptable, refer to section 15 of the

Q87. On drawing SRB-62, Full width bearing stiffener details, a 3/8'' fillet weld is shown
between the 1'' connection plate and bearing plate. On the same drawing, details for section
E-E & D-D are showing a CJP weld.
Can we get this clarified?
A87. The 3/8” fillet welds are intended for the vertical sides of the stiffener. The CJP welds are
for the bottom welds only. Drawing SRB-62, Sections D-D and E-E should show 3/8”
fillet welds on the vertical sides of the plate.

Q88. As part of Item No. 606.30330008 and per Dwg No. GRD-7 (Sheet No. 150/950), Sections
A-A, B-B and C-C it indicates #4 stirrups are required. Please provide the spacing of the
#4 stirrups.
Also please verify this 40’ long special transition section can be split into two (2) 20’ long
sections. If not, then it will weigh 73,500 lbs. (+/-) and may not be able to be delivered and
set in one 40’ long precast section. Verify what the joint if two sections are made would
be. Assuming a typical flat butt joint w/ closed cell foam like other precast barrier on this
project. Please confirm.
A88. Stirrup spacing shall be as specified on standard sheet 606-36. The barrier section can be
precast in two pieces with a typical barrier joint separating the pieces.
