00195.10  Asphalt Cement Material Price Escalation/De-escalation - An asphalt cement escalation/de‑escalation clause will be in effect during the life of the Contract.
The Agency reserves all of its rights under the Contract, including, but not limited to, its rights for suspension of the Work under 00180.70 and its rights for termination of the Contract under 00180.90, and this escalation/de-escalation provision shall not limit those rights.
(a)  Monthly Asphalt Cement Material Price (MACMP) - The Monthly Asphalt Cement Material Price (MACMP) will be established by the Agency each month. For information regarding the calculation of the MACMP, and for the actual MACMP, go to the Agency website at:
http://www.oregon.gov/ODOT/HWY/ESTIMATING/asphalt_fuel.shtm
If the Agency selected index ceases to be available for any reason, the Agency in its discretion will select and begin using a substitute price source or index to establish the MACMP each month. The MACMP will apply to all asphalt cement including but not limited to paving grade, polymer modified, and emulsified asphalts, and recycling agents. The Agency does not guarantee that asphalt cement will be available at the MACMP.
(b)  Base Asphalt Cement Material Price (Base) - The Base asphalt cement material price for this Project is the MACMP published on the Agency website for the month immediately preceding the bid opening date.
(c)  Monthly Asphalt Cement Adjustment Factor - The Monthly Asphalt Cement Adjustment Factor will be determined each month as follows:


  • If the MACMP is within ± 5% of the Base, there will be no adjustment.




  • If the MACMP is more than 105% of the Base, then:

Adjustment Factor = (MACMP) - (1.05 x Base)




  • If the MACMP is less than 95% of the Base, then:

Adjustment Factor = (MACMP) - (0.95 x Base)


(d)  Asphalt Cement Price Adjustment - A price adjustment will be made for the items containing asphalt cement listed below. The price adjustment as calculated in (c) above will use the MACMP for the month the asphalt is incorporated into the Project. The price adjustment will be determined by multiplying the asphalt incorporated during the month for subject Pay Items by the Adjustment Factor.
The Pay Items for which price adjustments will be made are:
Pay Items

PG 64-22 Asphalt in Level 3, ½ Inch Dense Lime Treated HMAC

PG 64-22 Asphalt in Level 3, ½ Inch Dense Lime Treated HMAC In Leveling

Emulsified Asphalt for Tack Coat

Add the following subsection:


00195.11  Fuel Cost Price Escalation/De-escalation - A fuel escalation/de‑escalation clause will be in effect during the life of the Contract.
The Agency reserves all of its rights under the Contract, including, but not limited to, its rights for suspension of the Work under 00180.70 and its rights for termination of the Contract under 00180.90, and this escalation/de‑escalation provision shall not limit those rights.
(a)  Monthly Fuel Price (MFP) - A Monthly Fuel Price (MFP) will be established by the Agency each month. For the actual MFP, go to the Agency website at:
http://www.oregon.gov/ODOT/HWY/ESTIMATING/asphalt_fuel.shtml
The MFP for a given month will be the average weekly price obtained from the OPIS weekly listing dated the first Monday of that month for No. 2 diesel fuel for Portland, Oregon. Prices are based solely on rack and resellers' prices exclusive of freight, taxes, and special discounts. If the average weekly price is not posted by OPIS or is otherwise not available to the Agency for the first Monday of any month for any reason, the Agency may use the average weekly price posted by OPIS immediately before or after the first Monday of that month. If the average weekly prices cease to be available from OPIS for any reason, the Agency in its discretion will select and begin using a substitute price source or index to establish the MFP each month. The Agency does not guarantee that fuel will be available at the MFP.
(b)  Base Fuel Price (Base) - The Base fuel price for this Project is the MFP published on the Agency website for the month immediately preceding the bid opening date.
(c)  Monthly Fuel Adjustment Factor - A Monthly Fuel Adjustment Factor will be determined each month as follows:


  • If the MFP is within ± 25% of the Base, there will be no adjustment.




  • If the MFP is more than 125% of the Base, then:

Adjustment Factor = (MFP) - (1.25 x Base)




  • If the MFP is less than 75% of the Base, then:

Adjustment Factor = (MFP) - (0.75 x Base)


(d)  Fuel Price Adjustment - A fuel price adjustment for fluctuations in the cost of fuel will apply only to the major fuel usage Pay Items shown in the following list and at the respective fuel factors listed:


Item Fuel Factor
Bridge Deck Cold Plane Pavement Removal, 0-2 0.04 Gal/SQYD

Inches Deep

Cold Plane Pavement Removal, 0 – 2 Inches Deep 0.04 Gal/SQYD

Cold Plane Pavement Removal, 2 – 4 Inches Deep 0.04 Gal/SQYD

Cold Plane Pavement Removal, 2 Inches Deep 0.04 Gal/SQYD

Level 3, ½ Inch Dense Lime Treated HMAC 2.93 Gal/TON

Level 3, ½ Inch Dense Lime Treated HMAC In Leveling 2.93 Gal/TON

The Contractor is cautioned to consider that its operations may require more or less fuel.


A price adjustment () to the Contractor for fuel cost changes will be made monthly if the Monthly Fuel Price differs 25% or more from the Base Fuel Price. This adjustment will be the product of the Monthly Fuel Adjustment Factor and the estimated Monthly Fuel Used. The Monthly Fuel Used will be determined by multiplying the quantities of Work accomplished during the month for subject Pay Items, by the appropriate Fuel Factors.

Fuel requirements for constructing the Project have been estimated at 117,826.00 gallons, based on fuel factors shown.


If the Contractor elects to use an alternate fuel (natural gas, wood pellets, propane, or other), the estimated fuel requirements will not be revised. Fuel cost adjustments will continue to be made as specified and will not be revised.

00195.12(a)  Steel Material Price Escalation/De-Escalation Participation - In the sentence that begins "Before or within…" of the paragraph that begins "The Contractor may select…", replace the words "five business days" with "seven Calendar Days".
00195.12(d)  Steel Materials Pay Item Selection - Add the following to the end of this subsection:
The Contractor may elect to participate in the steel escalation/de-escalation program for this Project under 00195.12 through 00195.12(d) by marking each check box for each Pay Item in the list below the Contractor is selecting for participation in the program. The completed list must be submitted in writing, signed and dated by the Contractor, to the Project Manager before or within seven Calendar Days after the date of the preconstruction conference.
PARTICIPATE PAY ITEM DESCRIPTION COST BASIS (CB)
□ Guardrail, Type 2A 11%

□ Guardrail, Type 3 11%


Regardless of the number of Pay Items listed by the Agency or selected by the Contractor, or if no Pay Items qualify for the steel escalation/de-escalation program for this Project or the Contractor elects not to participate in the steel escalation/de-escalation program for this Project, the steel price escalation/de-escalation clause (and program) contained in 00195.12 through 00195.12(d) are included in this Contract and are the only steel price escalation/de-escalation clause (and program) that apply to this Contract.

Section 00305, which is not a Standard Specification, is included for this Project by Special Provision.


Description
00305.00  Scope - This work consists of all surveying activities necessary to control the many phases of work required to construct the Project to the lines and grades as shown, specified, or established.
Make all supporting computations and field notes required for control of the work and as necessary to establish the exact position, orientation, and elevation of the work from control stations, including furnishing and setting construction stakes and marks, reference marks, and additional control stations.
Plans, specifications and other data necessary to lay out the work will be available for inspection at the Project Manager’s office.
00305.01  Definitions:
Confidence Points - Random points measured in the field within the boundary of a digital terrain model (DTM), the purposes of which are to verify the accuracy of the DTM and to provide evidence just prior to construction that the DTM is a reasonable representation of the original ground for computation of volumes and pay quantities. Similarly, confidence points are used to verify that a constructed grade has been built according to the design DTM. Additional information is available from the Engineer.
Confidence point locations follow these guidelines:


  • Randomly selected without regard for the location of DTM points or triangles

  • Evenly distributed over the entire DTM area to be validated

  • Proportionately distributed between confidence point classifications as applicable

  • At a density sufficient to validate the surface, generally ten per instrument location as used in collecting DTM data or if not applicable, as in data collected photogrammetrically, 2% of DTM points


Control Network - An array of control stations either established by the Contractor or provided by the Agency.
Control Station - Any item identified in the Project records as having a position and/or elevation on the Project datum and intended to be used to control the many phases of the construction work.

Digital Terrain Model (DTM) - An electronic computer model of the shape of the ground.
Reference Stakes - Stakes set away from but with information relating back to the intended location and/or grade.
Slope Catch - The location where a design slope intersects the existing ground and where excavation or embankment work should begin to provide the intended earthwork.
Slope Staking - The process of using measurements and calculations in the field to determine the slope catch. Slope staking shall normally include setting stakes to mark the slope catch and setting a reference stake for every catch stake.
Stakes - Stakes, nails, marks, string lines, or other devices or mechanisms set or established for the purpose of indicating or controlling the location, orientation, or grade of any feature intended for construction, or for the purpose of limiting or influencing the construction work.
Staking - The act of placing stakes.
Survey Marker - Any survey monument, control station, or stake.
Survey Monument - Any natural or man-made item specified or identified in a property deed, boundary survey, government document, or other instrument of public record, when the purpose of said item is to mark or reference a property boundary, geographical location, elevation, or other position.
Surveyor - The individual designated by the Contractor and licensed in the state of Oregon as a Professional Land Surveyor and placed in "responsible charge" of the survey work as defined in ORS 672.002(6)(b).
Temporary Bench Mark (TBM) - A control station established for the purpose of providing vertical control for the Project. A TBM may or may not have an established horizontal position.
00305.02  Mandatory Pre-Survey Conference - The prime Contractor, subcontractors, surveyor, survey crew leader, and all surveying personnel who are to be involved in the survey work shall meet with the Project Manager two weeks prior to beginning survey work.

The confidence point analysis will use the tolerance value defined in 00305.40 for the particular course, and will be deemed unacceptable if less than two-thirds of all confidence points meet the tolerance or if any confidence points exceed the tolerance by a factor of three or more.
The Engineer will evaluate the grade and provide acceptance or rejection before the end of the first business day following receipt of the confidence point data. Do not begin placement of the next course until the Engineer has accepted the grade and approval is given to proceed.

Stake drainage facilities, electrical conduits, water and sewer pipes, pedestrian and bicycle facilities, traffic signal and sign supports, illumination devices, and other items shown or identified that are to be integrated into the construction of the bridge.
Identify marks or provide field notes or reports to the Engineer. Such provision of information shall be adequate for the Engineer to review the location and elevation of the mark for the intended purpose prior to incorporating material that is based on the mark.
(a)  Bridge Survey Control Stations - Use the smallest number of original Project control stations as is practical for establishing positions and reference points for bridge construction on one bridge. Use of multiple control stations will increase the probability of incorporating error into the construction. Use control stations that are as closely related mathematically as practical. The Contractor may establish additional control stations as necessary to complete the survey work. Additional control stations shall be established in such a manner as to provide the accuracy needed to meet the tolerances in 00305.40.
Original Project control stations shall be used only after the following evaluation is completed for each bridge:


  • Supply a list of original Project horizontal and vertical control stations intended by the Contractor to be used in establishing positions on a given bridge.

  • Measure relative positions of original Project horizontal control stations intended to be used.

  • Measure elevation differences between original Project vertical control stations intended to be used.

  • Supply horizontal and vertical measurement data to the Engineer.

  • Compare measured values with those computed from original horizontal network coordinates and vertical network elevations.

  • Any discrepancy of concern to either the Contractor or the Engineer will be resolved before that combination of control stations is used.


(b)  Layout Marks and Reference Points:
(1)  Substructure - Stake, reference, or otherwise identify locations, orientations, and elevations necessary for placement of substructure components, including but not limited to cofferdams, pilings (including batter), footings, columns, abutments, caps, cross beams, bearing devices, temporary supports or falsework, and excavations and embankments associated with any of the above.
Verify and document the locations, elevations and spatial relationships with adjacent substructure components. On bridges where prefabricated beams will be used, measure and document span lengths between bearing devices at each beam location as soon as practical. Supply a copy of such documentation to the Engineer for review before the next stage of construction.
Compute the final elevations after studying the plans, specifications, and shop drawings. Adjust the grades as needed to compensate for camber of prefabricated beams, chording of beams across the low side of superelevations, width of flat beams on superelevated surfaces, and any other factor resulting from design or construction methods.
(2)  Superstructure - Stake, reference or otherwise identify locations, orientations, and elevations necessary for placement of superstructure components including but not limited to beams, girders, diaphragms, earthquake restraints, deck, rails, structure mounted traffic control and illumination devices, and concrete forms, temporary supports and falsework associated with any of the above.

Stake alignment of structure as needed at each stage of construction. Stake alignment of poured-in-place items at 10 foot stations or as established by the Engineer. Stake alignment for the following items as needed to maintain the horizontal tolerance defined in 00305.40:




  • Outside edge of girder(s).

  • Face(s) or centerline(s) of internal girders or stem walls.

  • Edge of deck.

  • Alignment of grade breaks.

  • Pedestrian and bicycle facilities.

  • Rails and railings.

Stake grades at each stage of construction. Stake grade of poured-in-place items at 10 foot stations, or as established by the Engineer. Apply corrections to design grades based on the dynamics of the evolving structure. Corrections that may be required depend upon the design of the bridge and the construction methods employed. Provide correction values to the Engineer at least 15 working days prior to incorporating into the structure. The following list is examples of possible corrections:




  • Design camber (upward adjustment to compensate for anticipated deflection).

  • Structural deflection (deflection of the bridge under its own increasing weight).

  • Post tensioning lift (upward movement of the bridge under post tensioning forces).

  • Structural shifting (dynamics of the bridge under eccentric loading).

  • Falsework deflection (deflection of falsework beams under increasing weight).

  • Falsework crush (compression of falsework supports under increasing weight).

  • Form crush (compression of forms under increasing weight).

  • Equipment deflection (deflection of deck finishing machine or deck rails).

  • Other adjustments to staked value to achieve the design grade.


(c)  Bridge Deck Grades - Set stakes or other devices to control the deck grade elevations. The exact process will depend upon the type of deck and the equipment being used. Stake and construct finished deck grades within the tolerances of 00305.40.
(1)  Portland Cement Concrete Deck - The surveyor and survey crew leader shall attend the first of the two deck pre-placement conferences, described in 00540.02(a), required for each deck placement.
Control of a PCC deck may involve significant work with the deck placement crew to establish control for a deck finishing machine. Rails for supporting the deck finishing machine are generally set up on either side of the deck. Each rail is held up by adjustable supports every 5 feet. Adjust the rail at each support to the desired grade while the rail is supporting the weight of the finishing machine. Corrections may need to be applied as listed in 00305.51(b-2).
(2)  Asphaltic Concrete Deck - Control of an AC deck will not generally involve as many variables as PCC. An AC deck serves as a wearing surface, but not a structural component. Asphaltic concrete will frequently be used as filler to create the desired superelevations when flat beams form the superstructure. Stake control of the finish grade like any asphalt finish grade. Under some circumstances, design camber and structural deflection may need to be considered.
00305.52  Pavements - Set stakes or other control devices to control the location and elevation of asphalt and PCC pavement as shown. Provide surveying or survey-related activity necessary to control grade, thickness, and smoothness as required.

















Temporary
00305.60  Temporary Protection and Direction of Traffic - Provide all work zone signing conforming to "ODOT Signing and Flagging Standards for Short Term Work Zones 1998" and "Short Term Traffic Control Handbook for ODOT Survey Crews 1998".

Maintenance and Monumentation
00305.70  Preservation of Survey Markers:
(a)  Project Control Points Established by the Engineer - Maintain, relocate or replace existing survey monuments, control points, and stakes, as determined by the Engineer. Perform the work to produce the same level of accuracy as the original monument(s) in a timely manner, and at no additional cost to the Agency.
(b)  Monuments of Record - Preserve survey monuments according to 00170.82(c), and ORS 209.140 and ORS 209.150. If such monuments are to be disturbed or destroyed, comply with requirements of these ORS at no additional cost to the Agency.
00305.71  Project Monumentation - The Contractor will not be responsible for performing right-of-way monumentation.
Measurement
00305.80  Measurement - No measurement of quantities will be made for construction survey work.
Payment
00305.90  Payment - The accepted quantities of performing construction survey work will be paid for at the Contract lump sum amount for the item "Construction Survey Work".

The amount to be allowed for "Construction Survey Work" in the progress payments will not be in excess of the reasonable value of the surveying work performed under this specification as said reasonable value is estimated by the Engineer.
Costs incurred as a result of survey errors will be borne by the Contractor. Such costs include price adjustments for failure to meet requirements of the construction specifications, repair or removal and replacement of deficient product, and over-run of material.

Take corrective action when required by the MDV start-up process of 00745.16(b‑1‑c). After the requirements of 00745.16(b-1-c) have been met, take corrective action if the MDV test results show that two consecutive running average of four samples are outside the above limits for air voids, VMA, VFA, or P No. 200/Pbe ratio. Document the corrective action and notify the Engineer. If test results continue to be outside the tolerance, stop production and make adjustments. Restart production only after the Engineer has approved the proposed adjustments. If the MDV test results are outside tolerance, but the mixture meets the current requirements for gradation and asphalt content, an adjustment to the JMF targets is required. Do not start a new lot as a result of the adjustment.
A request for an adjustment to the JMF targets may be made to the Engineer by the Contractor’s CAT-II. The requested change will be reviewed and documented by the Engineer. If acceptable, a revised JMF will be allowed. Clearly document the sublot test for which the adjusted targets are in effect. Adjustments for gradation shall not exceed the tolerances specified for the original JMF limits. Adjustments for AC content shall be within 0.5% of the original JMF. The JMF asphalt content may only be reduced if the production VMA meets or exceeds the above requirements. Adjustments for RAP content shall be within 5% of the original JMF, but shall not exceed the requirements of 00745.03. Regardless of these tolerances, the adjusted JMF shall be within the mixture specification control points of 00745.12. If a redesign of the mixture becomes necessary, submit a new JMF according to the requirements of these specifications.
Perform a Tensile Strength Ratio (TSR) test (AASHTO T 283) on a sample obtained during the first two days of production after QC test results verify that HMAC constituents with a weighting factor greater than one according to 00745.95 are in tolerance. Provide test results to the Engineer within four working days of obtaining the sample. Stop production and make adjustments if the TSR is less than 70. Restart production only after the Engineer has approved the proposed adjustments.
b.  Laboratory Compactor Selection - Use a Gyratory compactor for MDV when a Gyratory compactor is used to develop the JMF. For all other cases, use a Gyratory compactor or Marshall compactor, as selected by the Contractor.
c.  MDV Requirements at Start-Up - Perform MDV testing at the start-up of the JMF production according to the following process:
1. Obtain a sample during the first 100 tons of production and immediately perform MDV testing.
2. If air voids and VMA are within tolerance, then continue remaining MDV testing at the established random QC sublot interval. If not, then go to step "3".
3. If air voids and/or VMA are out of tolerance according to 00745.16(b-1-a), then make adjustments and immediately obtain another sample and perform MDV testing. Go to step "4".
4. If air voids and VMA from the MDV testing in step "3" are within tolerance, then continue remaining MDV testing at the established random QC sublot interval. If not, go to step "5".
5. If air voids from step "3" are more than  1.5% from the target, then stop production immediately and make adjustments. If they are not, then go to step "6". Obtain approval of the Engineer before restarting production. Begin MDV testing again at step "1".
6. If air voids from step "3" are out of tolerance and 1.5% or less from the target, or the VMA from step "3" is out of tolerance, then make adjustments and immediately obtain another sample and perform MDV testing. Go to step "4".
The initial MDV sample shall be used as the first random QC sublot test. Subsequent MDV samples required due to failure of start-up criteria will be used for a sublot QC test if the sample is taken within 100 tons of the scheduled random QC sample location. If not, the MDV testing shall be performed separate from, and not included in, the random QC testing program. Any required MDV testing will be completed at the Contractor’s expense.
Add the following subsection:
