Fuel Cost Adjustment
General
The Contracting Agency will make a fuel cost adjustment, either a credit or a
payment, for qualifying changes in the index price of on-highway diesel fuel. The
adjustment will be applied to partial payments made according to Section 1-09.9.
The adjustment is not a guarantee of full compensation for fuel price changes. Any
adjustment provided by this provision shall not obligate the Contracting Agency for
any costs due solely to changes in fuel costs beyond the amount adjusted by this
provision. The Contracting Agency does not guarantee that fuel will be available at
the base fuel cost or monthly fuel cost. No additional adjustment will be made for
rates of fuel consumption or actual fuel types that differ from those specified for the
purpose of determining the adjustment.
For the purpose of calculating the adjustment, the Base Fuel Cost shall be the Weekly
fuel price from the U.S. Energy Information Administration website. The website
location and directions are as follows:
• http://www.eia.gov/petroleum/gasdiesel/
Duvall Avenue NE ADDENDUM NO. 4
TED4004100 June 17, 2021
Page 4 of 11
• On the web page, click on the West Coast less California, listed under the heading
U.S On-Highway Diesel Fuel Prices*(dollar per gallon) at the lower end of the web
page.
• In the pull down box labeled Period pull down Weekly.
• Click on the fuel price history found under the column heading View History for
the line Diesel (On-Highway) – All Types.
• On this web page obtain the nearest weekly fuel cost for the Monday occurring
three weeks prior to the date that bids are opened. This weekly fuel cost becomes
the Base Fuel Cost and is fixed for the duration of the Contract and will be used in
calculating all adjustments.
The Monthly Fuel Cost shall be the most recent Monthly fuel price from the U.S.
Energy Information Administration website. The website location and directions are
as follows:
• http://www.eia.gov/petroleum/gasdiesel/
• On the web page, click on the West Coast less California, listed under the heading
U.S On-Highway Diesel Fuel Prices*(dollar per gallon) at the lower end of the web
page.
• In the pull down box labeled Period pull down Monthly.
• Click on the fuel price history found under the column heading View History for
the line Diesel (On-Highway) – All Types.
• On this web page obtain the most current monthly fuel price.
If the specified index ceases to be available for any reason, the Contracting Agency
at its discretion will select and begin using a substitute price source or index to
establish the Monthly Fuel Cost.
Measurement
No adjustment will be made if the Monthly Fuel Cost is within 10 percent of the Base
Fuel Cost. No adjustment will be made for work performed after the authorized Time
for Completion.
If the Monthly Fuel Cost is greater than or equal to 110% of the Base Fuel Cost, then:
Adjustment = (Monthly Fuel Cost – (1.10 x Base Fuel Cost)) x Q
If the Monthly Fuel Cost is less than or equal to 90% of the Base Fuel Cost, then:
Adjustment = (Monthly Fuel Cost – (0.90 x Base Fuel Cost)) x Q
Where Q = ((Fuel Usage Factor for each Eligible Bid Item) x (Quantity paid in the
current months progress estimate for each Eligible Bid Item)) for all Eligible Bid Items
listed below:

Steel Cost Adjustment
The Contractor may elect to participate in the steel cost adjustments for work
permanently incorporated into this Contract. Steel cost adjustment is not a
guarantee of full compensation for changes to the cost of steel items; not eligible for
all items with steel; and any adjustment provided by this provision will not obligate
the Contracting Agency for any costs beyond the amount adjusted by this provision.
This Special Provision provides the option to opt-in to steel cost adjustments for
eligible Bid items. The Contractor is provided one opportunity to opt-in and there are
no future opt-out provisions. The steel cost adjustment requirements of this Special
Provision apply for the duration of the Contract.
General
The Contractor may select Bid items from the list below to be included in the steel
cost adjustment. The Contractor is not obligated to select any Bid items or to
participate in the steel cost adjustment program. The steel cost adjustment will apply
only to the Bid items selected by the Contractor.
Prior to Contract execution the Contractor shall submit the Steel Cost Adjustment
Opt-In Bid Item List, WSDOT Form 410-031, to the WSDOT Contract Ad and Award
Office. The form is to be received at the WSDOT Bid Room, located at the
Transportation Building, 310 Maple Park Avenue SE, Room 2D20, Olympia, WA
98501-2361 or may be submitted by facsimile to the following FAX number, (360)
705-6966. The Steel Cost Adjustment Opt-In Bid Item List shall be signed by an
authorized representative of the Contractor. Should the Contractor fail to return this
document as required no Bid items will be eligible for steel cost adjustment.
Steel Index Values
Duvall Avenue NE ADDENDUM NO. 4
TED4004100 June 17, 2021
Page 6 of 11
The Contracting Agency will use the Bureau of Labor Statistics (BLS) producer price
index (PPI) series Id: WPUSISTEEL1 index value for steel cost adjustments.
The Base Steel Materials Index Value (BV) will be the most recent value published on
the BLS website on the day of bid opening. This value will be fixed on the d ay of bid
opening even if the BLS lists this as a preliminary value. The Monthly Steel Materials
Index Value (MV) will be the final index value published on the BLS website for any
month during the Contract.
Measurement
The Contracting Agency has determined the initial cost basis (ICB) of steel to be
*** $0.40/lb ***. This cost basis is reflected in the steel cost adjustment calculations
below, is non-negotiable and will be taken as a fixed value for the duration of the
Contract.
For each month that steel material is incorporated into the permanent Work of the
Contract or paid for as Materials on Hand and the MV is more than 110 percent or
less than 90 percent of the BV the Contractor shall provide the Engineer with the
following for each eligible Bid item by the end of the following month:
1. The weight of steel material for the month, and
2. Documentation of the weight and shipment to the Contractor of the steel
material by bills of lading, invoices, or purchase orders.
Should the Contractor not provide the required documentation as specified the
following shall apply:
1. Steel material that has an MV that is more than 110 percent of the BV will not
be eligible for a steel cost adjustment.
2. The steel cost adjustment for a Bid item with an MV that is less than 90 percent
of the BV will be calculated using a weight of steel determined by the Engineer.
Steel materials will not be eligible for cost adjustments until all requirements of the
Contract have been met. Steel added to a Contract as part of a Value Engineering
Change Proposal will not be eligible for steel cost adjustment. Steel cost adjustments
made in accordance with this Special Provision will not be reflected on payments
made to the Contractor until after the index value required for the calculat ion
becomes final. Preliminary index values may be used to establish the BV, but will not
be used to establish the MV in calculations.
For each Bid Item selected by the Contractor on the Steel Cost Adjustment Opt-In Bid
Item List form a cost adjustment evaluation will be made. A cost adjustment will only
Duvall Avenue NE ADDENDUM NO. 4
TED4004100 June 17, 2021
Page 7 of 11
be made if the MV for the month the Work associated with the Bid Item is performed
differs by more than ten-percent from the BV.
The steel cost adjustment will be determined as follows:
1. If the MV is within ten-percent of the BV, there will be no adjustment.
2. If the MV is more than 110-percent of the BV, then
CA = (((MV - BV) ÷ BV) - 0.10) × (ICB × WS)
3. If the MV is less than 90-percent of the BV, then
CA = (((MV - BV) ÷ BV) + 0.10) × (ICB × WS)
Where:
CA = Cost Adjustment, dollars
MV = Monthly Steel Materials Index Value from BLS for the month determined above
BV = Base Steel Materials Index Value taken as the most recent value published on
the BLS website on the day of bid opening.
ICB = Initial Cost Basis of steel per pound
WS = Weight of steel (in pounds) eligible for cost adjustment
The following Bid Items are eligible for the steel cost adjustment program for this
Project:
*** All mailboxes support posts included under Section 8-18 of these Special
Provisions
All poles included under Section 8-20 of these Special Provisions ***
Payment
Payment will be made for the following bid item when included in the bid proposal:
“Steel Cost Adjustment”, by calculation.
To provide a common proposal for all bidders, the Contracting Agency has entered
an amount in the proposal to become a part of the Contractor’s total bid.
