WSDOT Standard Specifications
Ordinance adopting the current version of Specifications
ISSUE
Local agencies utilizing federal funds for transportation contracts must incorporate and
adopt the 2012 Standard Specifications, as published by the Washington State
Department of Transportation and the Washington State Chapter of the American Public
Works Association (WSDOT /APWA).
BACKGROUND
Previously, the 2010 WSDOT /APWA Standard Specifications for Road, Bridge and
Municipal Construction was adopted by City of Tukwila Ordinance No. 2284. A new
ordinance has been prepared and adopted every two years concurrent with the WSDOT
update schedule.
The 2012 edition of the Standard Specifications has been published by WSDOT /APWA
with minor technical changes from the 2010 edition. Examples of some of the revisions
are attached. City staff is currently revising and updating our construction contract
boilerplate documents and General Special Provisions (GSP's) accordingly. Local
agencies must adopt the 2012 Standard Specifications for use in all federally funded
projects advertised on or after April 2, 2012.
DISCUSSION
An ordinance has been drafted to adopt the 2012 edition as well as anv future updated
editions of the Standard Specifications, General Special Provisions and Construction
Contract Boilerplate documents. This ordinance will also repeal the previous Ordinance
No. 2284 as well as eliminate the need to adopt a new ordinance every two vears.
RECOMMENDATION
The Council is being asked to approve the ordinance adopting the all subsequent
editions or amendments to the WSDOT Standard Specifications and consider this item
at the March 12, 2012 Committee of the Whole meeting and subsequent March 19,
2012 Regular Meeting.

New Amendments to the 2010 Standard Specifications
Effective August 1, 2011
Please note: New Amendments to the Standard Specifications are described below.
Previous Amendments that are not revised in this package are still in effect.
Amendments to the Standard Specifications take precedence over the Standard
Specifications in accordance with Section 1 -04.2.
The following is a brief description of the latest revisions, with an explanation of why
each change was made. The actual provisions should be reviewed in depth to become
completely knowledgeable of the full extent of the revisions. These amendments are
available at the following location:
http://www.wsdot.wa.gov/Design/ProjectDev/Specifications
DIVISION 1 GENERAL REQUIREMENTS
Section 1- 07.5(3) State Department of Ecology
This amendment brings our specification into compliance with the new General
Construction Stormwater Permit (GCSP) that took effect January 1, 2011. The change to
this section was to include prohibited discharges.
Section 1- 09.2(5) Measurement
The amendment corrects this sections existing amendment by making it clear that under
weighing scales must be fixed immediately and Contractor will not be compensated for
any loss due to under weighing.
DIVISION 3 Production From Ouarry and Pit Sites and Stockpiling
Section 3- 01.4(4) Gravel Base
This amendment revises the section to remove reference to Stabilometer (R- Value) from
specifications and testing. The R -Value testing is not being employed by WSDOT to
perform a useful function in these applications.
DIVISION 4 Bases
Section 4 -02.4 Measurement
This amendment revises the section to remove reference to Stabilometer (R- Value) from
specifications and testing. The R -Value testing is not being employed by WSDOT to
perform a useful function in these applications.
DIVISION 5 SURFACE TREATMENTS AND PAVEMENTS
Section 5- 01.3(6) Dowel Bar Retrofit
Updates needed to specification for dowel bar retrofit per a review of specification from
Jt Northwest Chapter of the American Cone. Pavement Association and WSDOT
Concrete Pavement Team.
Ausut 1, 2011 Page I of 6
MJG:mjg
New Amendments to the 2010 Standard Specifications
Effective August 1, 2011
Section 5- 02.3(3) Application of Asphalt Emulsion and Aggregate
This amendment removes the gradation of 318 to #10 from the standard specifications.
Only one Region has been using the gradation for BST and they are moving away from
its use as it acts poorly.
Section 5- 04.3(5)E Pavement Repair
This is a change to an existing amendment. The previous amendment had a minimum
width of 42- inches for any pavement repair area. This amendment changes that width to
40- inches per WAPA whom stated that 40- inches was a better width for their planing
machines.
Sections: 5- 04.3(7)AI, 5- 04.3(7)A2, and 5- 04.3(7)A3
Section 5- 04.3(7) is amended to addresses changes to be made to HMA mix designs
process. WSDOT no longer does HMA mix design verification, but do determine the
anti strip requirements for each HMA mix design.
Sections: 5- 04.3(7)AI— General, 5- 04.3(10)A- General, 5- 04.3(10)B4 -Test Results and
5- 04.3(11)D -Lots and Sublot
Changes in these amendments clarify when a new mix design may be required due to
changes to the percentage of material from a stockpile, static roller usage, HMA rejection
and proposal for approval, and other minor editorial changes.
Section 5- 05.3(4)A Acceptance of Portland Cement Concrete Pavement
Updates in statistical and non statisticscal acceptance of concrete based upon a review of
specification by Jt Northwest Chapter of the American Cone. Pavement Association and
WSDOT Concrete Pavement Team.
Section 5- 05.3(11) Finishing
Changes to an existing amendment on the areas where finishing cement cone. Maybe
longitudinal tining or texturing with a comb.
DIVISION 6 STRUCTURES
Section 6 -01.13 Architectural Features
This amendment deletes this section and changes the title to Vacant. This was done
because we never define architectural features and there are a lot of characteristics of
concrete that affect color (aggregate, fly ash, cement qty and other none of which are
controlled by this section.
Section 6 -01.14 Premolded Joint Filler
This amendment changes Section 6 -01.14 to delete the ASTM reference and replace it
with a direct reference to Section 9- 04.1(2).
Section 6- 02.3(5)E Point of Acceptance
This amendment adds the term "bridge approach slabs" to those items where
determination of concrete properties will be made at the point of placement.

New Amendments to the 2010 Standard Specifications
Effective August 1, 2011
Section 6- 02.3(17)K Concrete Forms on Steel Spans
This amendment requires the Contractor to design bridge deck form systems to prevent
rotation of the steel girder.
Section 6- 02.3(17)N Removal of Falsework and Forms
This amendment repaces the existing amendment done in January 4, 2010. The new
amendment clarifies the previous amendment with specifics on the types of fors that can
be removed and other formatting changes to make the table easier to read.
Section 6- 02.3(25)G Protection of Exposed Reinforcement
Since 1984, WSDOT has required that all steel reinforcing bars extending from
prestressed concrete girders be painted with a zinc rich primer paint upon removal of the
girder from its casting bed. The requirement is based on experience during the Olympia
Freeway construction projects beginning in the early 1980's where surface corrosion of
unprotected extended steel reinforcing bars stained the surface of the girder webs exposed
to public view. The attached revision adjusts the requirement for protecting extended
steel reinforcing bars by referencing Section 6- 02.3(24)B, which allows the Engineer to
require painting of the bars if they are to be exposed for a length of time deemed
excessive for unprotected exposure. The attached revision also clarifies that extended
prestressing reinforcement is to be painted in all cases.
Section 6- 02.3(25)I Fabrication Tolerances
This revision to the specified horizontal tolerance for placement of lifting loops brings
the Standard Specification into conformance with the revised placement tolerances
specified in the design criteria of WSDOT LRFD Bridge Design Manual 5.6.3C
Section 6- 02.3(25)M- Shipping
The current specification dates back to an August 2007 Amendment requiring the girder
bunk locations be as shown in the Plans based on design in accordance with WSDOT
LRFD Bridge Design Manual 5.6.3D. The PNW/PCI fabricators requested some
flexibility be provided. This revision adds a restriction on the minimum dimension from
the end of girder to the bunk location that is consistent with current WSDOT design
criteria.
Sections 6- 02.3(26)A, 6- 02.3(26)B, 6- 02.3(26)C, 6- 02.3(26)D and 6- 02.3(26)G
Section 6- 02.3(26) was extensively revised in August 2001. These provisions have been
surpassed by more recent design code changes implemented by AASHTO. After a
comprehensive review by Bridge and Structures Office these sections are revised to
bring specification and WSDOT practices regarding post- tensioning, into conformance
with current AASHTO design and construction codes and with industry practice.
Sections: 6 -02.4 Measurement and 6 -02.5 Payment
Amendment to 6 -02.4 was done to specify that the computed weight of steel includes
mechanical splices, based on the weight of the splice as specified in the manufacturer's
catalog cut for the specific item. Item 2 is also revised to clarify that splices specified as
Ausut 1, 2011 Page 3 of 6
MJG:mjg
21
New Amendments to the 2010 Standard Specifications
Effective August 1, 2011
"optional" are to be furnished without extra allowance the same as for other splices not
shown in the Plans. Amendment to 6 -02.5 is revised to specify that splicing is included
in the steel reinforcing bar bid item. Also, the bid item names are revised to add a fill -in
blank at the end of the name to bring them into conformance with the Standard Item table
naming convention.
Section 6- 03.3(7)A Erection Methods
This amendment removes the requirement for steel fabricators to review and approve the
Contractors erection plan, since steel fabricators and erection are completely separate
operations.
Section 6- 03.3(39) Swinging the Span Erection Methods
This amendment allows the placement of bridge deck forms prior to swinging the girders
provided uniformly distributed weight of forms is less than or equal to 5 pounds per
square foot.
Section 6 -05.5 Payment
This amendment was done to include furnishing steel reinforcing bar in the bid item
"Cast -in -Place Concrete Test Piles Ambiguity in the existing specification has led to
confusion and change orders to provide extra payment for furnishing reinforcing steel for
this item.
Section 6- 07.3(9)I Application of Field Coating
When Section 6 -07 was revised in August 2009, the requirement for preparing uncoated
surfaces prior to applying field primer was inadvertently left out of the specification. This
revision closes the gap in the specification by inserting into Section 6- 07.3(9)I the
missing requirement to prepare all uncoated surfaces, including bolts, nuts, washers and
splice plates, upon completion of erection work in accordance with Section 6- 07.3(9)F
Section 6- 13.3(2)A Design Calculation Content Requirements
This amendment revises an earlier amendment. Due to an FHWA requirement that wall
designs conform to AASHTO LRFD Bridge Design Specification, the WSDOT design
approach for structural earth walls is changing. As a part of this revised design approach
WSDOT will be responsible for specifying the length of soil reinforcement. This revision
removes ambiguity regarding the required length of soil reinforcement in Item No. 7.
Section 6 -13.5 Payment
This amendment adds the term, `copings' as being incidental to the unit contract price for
"Structural Earth Wall This was done because more projects are incorporating sensitive
aesthetic ornamentation into various structure elements.
Section 6- 17.3(7) Installing Permanent Ground Anchors
The existing amendment to this section is Deleted as it was in conflict with sixth
paragraph of the section which allowed installation of anchors in a wet or dry hole.

New Amendments to the 2010 Standard Specifications
Effective August 1, 2011
DIVISION 7 Drainage Structures. Storm Sewers. Sanitary Sewers. Water Mains,
and Conduits
Section 7 -09 Water Mains
Three amendments to sections; 7- 09.3(24)A, 7- 09.3(24)N and 7 -09.5 to bring these
sections into compliance with the new General Construction Stormwater Permit (GCSP)
that took effect January 1, 2011. The change to these sections were to address
dechlorination of water before discharge.
DIVISION 8 MISCELLANEOUS CONSTRUCTION
Section 8- 01.3(1)A Submittals
This amendment rearranges content in the Section for better flow of content, and it makes
it clear that that modified TESC Plans have to meet the requirements of Chapter 6,
Section 6 -2 of the current edition of the WSDOT Highway Runoff Manual.
Section 8- 01.3(1)B Erosion and Sediment Control (ESC) Lead
This amendment brings this section into compliance with the new General Construction
Stormwater Permit (GCSP) that took effect January 1, 2011. The change supplements the
duties of the ECL for inspection of BMPs and discharge points.
Section 8- 21.3(9)F Foundations
This amendment changes item number 3, in the tenth paragraph, to state that unless the
Plans call out a different class of cement concrete, commercial grade cement concrete
will be used for roadside sign structures.
Sections:. 8-22.4 Measurement and 8 -22.5 Payment
These amendments add the new Pavement Marking item, Junction Box Markings.
DIVISION 9 MATERIALS
Section 9- 03.4(2) Grading and Quality
This amendment removes the column titled `3/8" No. 10' from the Table of this
Section. This gradation has been linked to poorly performing BST pavements.
Sections: 9 -03.10 Aggregates for Gravel Base, 9- 03.12(1)B Class B and 9 -03.20
Test Methods for Aggregates
These amendment revise the sections to remove reference to Stabilometer (R- Value)
from specifications and testing. The R -Value testing is not being employed by WSDOT
to perform a useful function in these applications
Section 9- 05.12(1) Solid Wall PVC Culvert Pipe, Solid Wall PVC Storm Sewer
Pipe, and Solid Wall PVC Sanitary Sewer Pipe
This amendment changes 115 psi pipe stiffness to 46 psi in this Section. The higher
strength pipe is hard to find and expensive and after further review the 46 psi pipe
stiffness would be sufficient for WSDOT needs.

New Amendments to the 2010 Standard Specifications
Effective August 1, 2011
Section 9- 06.5(4) Anchor Bolts
This amendment is revised to include reference to AASHTO M 292, Grade H. The
Bridge Office has been receiving request to approve this material and concurs with the
assertion that the material is equivalent to the specified AASHTO M 291 /ASTM A 563
Grade DH material if overtapping, lubrication and rotational testing required in Section
9- 06.5(3) is satisfied.
Section 9 -07.2 Deformed Steel Bars
This amendment updates the specification to assure that ASTM A 706 Grade 60 is used
for bridge and structures elements.
Sections: 9 -23.9 _Fly Ash and 9 -23.10 Ground Granulated Blast Furnace Slag
The new amendments detail the quality control, tests and acceptance methods, for Fly
Ash and Blast Furnace Slag. These changes have been discussed with WACA which did
not have any concerns. These new amendments formalizes the quality control program
for fly ash and slag that has been voluntary to date and parallels the program that we have
been performing on Portland cement.
Sections: 9- 29.1(4)A Rigid PVC Conduit and 9- 29.1(4)C HDPE Conduit
These amendments delete erroneous specifications in section 9- 29.1(4)A as ASTM F
2136 does not apply to PVC conduit, and adds additional clarification to section 9-
29.1(4)C concerning the requirements for HDPE Conduit that it be listed by the
Nationally Recognized Testing Laboratories (NRTLs) program.
Note: a previous amendment changed the section number of 9- 29.1(4)B HDPE
Conduit in the Book to section number 9- 29.1(4)C HDPE Conduit.
Sections 9- 34.4(1) Geosynthetic Material Approval, 9- 33.4(3) Acceptance
Samples and 9- 33.4(4) Acceptance by Certificate of Compliance
These amendments to geotextile for underground were made to reduce the quantity of
material for testing from 600 sy to 100 sy because for the typical underdrain, this is
equivalent to 600 linear feet of drain. Considering that such underdrains could be used
behind retaining walls to keep water out of the backfill, or at road edge to keep water out
of the base /subgrade, this is a lot of length of such features that potentially could fail if
the geotextile is inadequate to promote the drainage needed.

Staff is seeking Council approval for Construction Management Supplement No. 2 with CH2M Hill in the
anount of $81.047.80 for the TUC Access (hlickitat) Project. With the holiday traffic moratorium and the
heavy snow in Jvnuary 2012, construction management services need to be extended to June 30, 2012. The
budget for construction managcmcut remains the same, but the City construction management staffing estimate
Of V)02_775.20 was reduced to compensate for the additional CH2M Hill supplement. UNANIMOUS
APPROVAL. FORWARD TO MARCH 12 COW FOR DISCUSSION.
B. Ordinance: 2012 WSDOT Standard Specifications
Staff is seeking Council approval for an ordinance adopting the 2012 WSDOT SUi ndard Specifications. The
ordinance is needed to adopt the Standard Specifications for any Federal Aid Projects so that the contract format
is the same across all jurisdictions. The mandated contract specifications are only in Division 1 of the WSDOT
Standard Specifications, whereas Divisions 2 through 9 can be modified to meet our specific Cit-,
requirements. There are only minor technical changes to the Division 1 contract boilerplates. The Committee
was concerned that there were not "substantial' changes and requested a synopsis of the 2012 updates if
available. The draft ordinance will repeal Ordinance No. 2284. After further discussion. staff will make an
inquiry to the City Attorney's office to see if the draft ordinance could be changed to reflect acceptance of all
fixture /subsequent editions to make this process more efficient. Again. the Committee and /or Council Nyould be
informed of anv significant changes made in these editions (i.e. such as changes made in 2014).
UNANIMOUS APPROVAL. FORWARD TO MARCH 1.2 COW FOR DISCUSSION.
C. Strander Blvd /SW 27 St Extension Phase III Grant Apolication
Staff is seeking Committee approval to apple for the Federal HighNNay Administration's TIGER IV grant for
Phase lll of the Stander Blvd Extension Project. Phase Ill is completeh in the City of Tuk%rila and will connect
Staander Boulevard from the Tukwila Longacres Station under the railroad tracks to West Vallev Hi ay.
At Committee, Bob announced that the Freight- Mobility Strategic Investment Board FMSIB) has pledged $5
million for Phase II1. With the $5 million. only $22 million will be requested from the TIGER IV grant as the
total project cost is estimated to be $27 million. Matching fiends are available from Phases I and II and
Tukvvila's contribution should be $0.00. This grant is very competitive, but the City of Renton and FMSIB arc
