     EQUAL EMPLOYMENT OPPORTUNITY-ASPIRATIONAL TARGET PROVISIONS


As used in these provisions, "Engineer" means the Chief Engineer of the Oregon
Department of Transportation acting either directly or through his authorized
representatives.

Section 140 of Title 23, United States Code, EQUAL EMPLOYMENT OPPORTUNITY, as in
effect on May 1, 1982, is incorporated by this reference and made a part of these
provisions.

                                       Written Notification

The Contractor shall provide written notification to the Engineer within 10 working days of
award of any construction subcontract in excess of $10,000 at any tier for construction work
under the contract resulting from this solicitation. The notification shall list the name,
address and telephone number of the subcontractor; employer identification number;
estimated dollar amount of the subcontract; estimated starting and completion dates of the
subcontract; and the geographical area in which the subcontract is to be performed.

In addition to the notification required in item 7d in the "On-Site Workforce Affirmative
Action Requirements for Women and Minorities on Federal-Aid Contracts", the Contractor
shall provide immediate written notification to the Engineer when the union or unions with
which the Contractor has a collective bargaining agreement has not referred to the
Contractor minorities or women sent by the Contractor, or when the Contractor has other
information that the union referral process has impeded the Contractor's efforts to meet its
equal opportunity obligations.

                                 Aspirational Diversity Targets

ODOT Aspirational Diversity Targets - While Aspirational Diversity Targets are not
requirements for this contract and are not binding on the contractor, ODOT desires to
encourage the highest possible participation of minorities and women in the work force.
Therefore, ODOT has established aspirational targets on OTIA III contracts statewide and
all ODOT construction contracts in Multnomah, Clackamas, and Washington counties as
follows:

                                         Covered Areas

                         Area                                 Aspirational

               ODOT Region 1                           Women 14% - Minority 20%
            ODOT Region 2, 3, 4, & 5                   Women 14% - Minority 14%

Neither Contractor nor its subcontractors are under any obligation to meet any aspirational
targets.

       REIMBURSABLE FEDERAL ON-THE-JOB and APPRENTICESHIP TRAINING

This Section for Reimbursable Federal On-the-Job Training and Apprenticeship Training
supersedes subparagraph B(7-e) of the "On–Site Workforce Affirmative Action
Requirements for Women and Minorities on Federal Aid Contracts," and is in
implementation of 23 U.S.C. 140(a). All other provisions apply.


SECTION 1: Abbreviations and Definitions

BOLI     - Bureau of Labor and Industries for the State of Oregon

OJT      - On-the-Job Training

Apprenticeship Training Program: A specific apprenticeship training program, approved
by BOLI, which provides a combination of field and classroom trade specific experience
under the supervision of journey level workers. For this Contract, this is a race and gender
neutral program.

OJT Program: A specific on-the-job training program developed by the Contractor,
approved by the Agency and FHWA (also includes previously developed standardized
training programs already approved by the Agency and FHWA), which provides a
combination of field, and limited classroom, trade specific experience under the supervision
of journey level workers. This is an Affirmative Action program and targets otherwise
disadvantaged woman and minorities.

Qualified Hours: Specific On-Site hours (may include some classroom hours) performed
by a properly registered and enrolled trainee consistent with their OJT Program or an
apprentice consistent with their Apprenticeship Training Program, and reported by the
Contractor to the Agency for the OJT Program and to BOLI for the Apprenticeship Training
Program.


SECTION 2: OJT Program and Apprenticeship Training Program Policy Statement

In order to increase the number of trained and skilled workers in highway construction the
Agency will set a training goal for the Project.

It is the policy of the Agency that the Contractor shall take all necessary and reasonable
steps, to ensure that trainees and apprentices have the opportunity to participate on
highway construction projects and to develop as journey-level workers in the given trade or
job classification employed, and to meet this training goal.

Training and upgrading minorities and women in highway construction trades is a primary
objective of the Agency. Accordingly, the Contractor shall make every effort to enroll
minority and women trainees in OJT Programs by conducting systematic and direct,
meaningful recruitment through public and private sources likely to yield minority and
women trainees within a reasonable area of recruitment. Although Apprenticeship Training
Programs are race and gender neutral, the Contractor shall ensure that, without
discrimination, minorities and women have an equal employment opportunity to compete for




Reimbursable OJT/Apprenticeship                                                  Page 1
N. Going Street Bridge Rehabilitation
Seismic Strengthening

and participate as apprentices and to support a diverse workforce that is representative of
the population.


SECTION 3: Affirmative Action Requirement

Whenever minorities or women are not placed in OJT positions, the Contractor shall
provide documented evidence of Affirmative Action recruitment efforts. The Agency will
review the documents of the Contractor’s systematic and direct, meaningful recruitment
efforts to determine whether the Contractor has complied with the criteria in "Required
Contract Provisions Federal-Aid Construction Contracts" (FHWA Form 1273), Section II
Nondiscrimination.

When filling OJT positions and apprenticeship positions, the Contractor and the
Subcontractors are encouraged to hire previously approved apprentices who have not yet
completed their training.

Neither the provisions of any collective bargaining agreement, nor the failure by a union
with whom the Contractor has a collective bargaining agreement, nor any agreement the
Contractor has with a joint apprenticeship and training committee, shall excuse the
Contractor’s obligations under these provisions. Nor shall these sources exclude qualified
minorities and women available for training for Work under this Contract.

The training goal is not intended, and shall not be used, to discriminate against any
applicant for training, whether members of a minority group or not.


SECTION 4: Assigned Training Goal Disincentive

The Agency will insert an hourly price and quantity for the Pay Item "Training". This hourly
price will be fixed.

For purposes of determining the Contractor’s total Qualified Hours, any combination of
Qualified Hours for OJT and Apprenticeship Training may be aggregated and summed
toward the training goal.

If the total number of Qualified Hours earned by the Contractor fails to meet the training
goal, this program contains a no payment clause (disincentive) according to Section 8
below.

Section 5: Training Requirements

The intent of these provisions is to provide real and meaningful training in the construction
crafts. Off-Site training is permissible only when it is an integral part of an approved training
program and does not comprise a significant part of the overall training. In addition:

   • The Contractor, not registered as a training agent, may choose to adopt a
     standardized OJT Program.




Reimbursable OJT/Apprenticeship                                                       Page 2
N. Going Street Bridge Rehabilitation
Seismic Strengthening

   • For non-standardized or new OJT Programs proposed by the Contractor, obtain
     approvals prior to beginning On-Site Work with employees in the classifications
     covered by the OJT Program.
   • OJT Programs may include carpenter trainee, cement mason trainee, ironworker
     trainee, utility trainee, and construction assistant or others when training is oriented
     toward construction vocations.
   • OJT Programs for laborers may be allowed if the Programs provide significant and
     meaningful training.
   • OJT Programs in classifications such as flagger, bookkeeper, clerk/typist or secretary
     are prohibited.
   • OJT Programs shall always maintain the approved ratio of trainees to journey level
     workers On-Site.
   • OJT Programs shall always maintain the approved types and numbers of equipment
     On-Site.
   • Where feasible, 25 percent of trainees shall be in the first year of an OJT Program for
     each classification.
   • No employee shall be registered as a trainee in any classification they have
     completed leading to journey level status, or for any classification they have been
     employed as a journey level worker. The Contractor shall keep records, and provide
     to the Agency, if requested, documents on each trainee.
   • Trainees shall be pre-approved, registered, enrolled and working On-Site.

OJT Program trainees shall be paid the journey level rate specified in the contract for the
type of work performed. Apprenticeship Program trainees shall be paid the appropriate
rates approved in connection with their stage in the Apprenticeship Training Program.

A valid certification by an appropriate apprenticeship committee that the Contractor is an
approved training agent shall be prima facia proof of compliance.


SECTION 6: Reports

The Contractor and each Subcontractor with an OJT Program or Apprenticeship Training
Program shall complete and submit the following reports to the Project Manager:

   • At the pre-construction conference, the Contractor shall submit a training program
     forecast on the "Training Program Form" (Form 731-0335).
   • For OJT trainees, submit an "In-House Trainee Approval Request" (Form 731-0503)
     to the Agency prior to the OJT trainee beginning work. Attach a copy of
     Form 731-0335, to Form 731-0503. The Contractor shall provide certification to the
     trainee upon completion of the OJT Program and submit a copy to the Agency Office
     of Civil Rights. Upon completion of the Contract, a certification shall be given to each
     trainee and to the Agency to document the number of hours and training completed
     by the individual.
   • By the tenth of each month, the Contractor shall submit to the Agency an "ODOT
     Apprentice/Trainee Monthly Progress Record" (Form 731-0332) for each trainee.

N. Going Street Bridge Rehabilitation
Seismic Strengthening

      Use Form 731-0332 to report Qualified Hours for either OJT trainees or apprentice
      trainees. This will be the source document for estimated monthly progress payments
      to the Contractor.
   • Contractor shall submit a "Monthly Employment Utilization Report" MEUR
     (Form 731-0394) by the tenth of each month. This report is required of the Contractor
     and Subcontractors on Subcontracts valued $10,000 and above, regardless of their
     participation in the apprenticeship or OJT Program.

Forms are published on the Office of Civil Rights website at:

http://www.oregon.gov/ODOT/CS/CIVILRIGHTS/forms.shtml

Forms may also be obtained from the Office of Civil Rights by calling 503-986-4350.


SECTION 7: Monitoring and Compliance

The Contractor has the primary responsibility to monitor compliance levels throughout the
Contract and to ensure the training goal is met. If the Contractor decides any of the training
hours are to be provided by a Subcontractor, the Contractor shall ensure that the
Subcontract contains the appropriate training clauses that obligate the Subcontractor. This
shall not relieve the Contractor of the Contractor’s primary responsibility.

Meet with the Agency monthly to review the progress records or apprenticeship records.
The Agency, through the monthly meetings and progress records or apprenticeship records
provided by the Contractor, will provide the Contractor with informational compliance and
reimbursement data including:

   • The Contractor’s training forecasts compared with the actual Qualified Hours
     achieved.
   • Total Qualified Hours and payment reimbursement summary.
   • For information purposes only, the monthly summary reports by OJT trainee craft and
     apprenticeship craft.

The Agency will track training activities provided by Contractor to the OJT trainees and
apprentice trainees.


SECTION 8: Measurement/Payment

   1. The Agency will establish the total Reimbursable OJT Program and Apprenticeship
      Training Program goal for the Project. This number of training hours will not be
      reduced except by Contract Change Order.

   2. The Contractor is expected to utilize all of the training hours on this Project. Check
      the training goal and the unit price in the Schedule of Items.




Reimbursable OJT/Apprenticeship                                                    Page 4
N. Going Street Bridge Rehabilitation
Seismic Strengthening

   3. If the Contractor achieves at least 100% of the goal, up to a maximum of 150% of the
      goal, the Agency will reimburse the Contractor for the Qualified Hours times the
      Pay Item price.

      Example: Agency goal = 1,000 hours; Pay Item = $20.00/hr; Contractor achieves an
      actual 1,525 Qualified Hours: therefore 1,500 hours x $20.00/hr = pay of $30,000.

   4. According to 00195, the Agency will pay for measured Pay Item quantities for
      "Training" performed according to this Contract.

   5. After the Second Notification, the Agency will review the final reports required in
      Section 6 and make adjustments. Any additional reimbursements will be paid on the
      Final Estimate.

   6. If, at the Second Notification, the Contractor has not achieved the training goal there
      will be no payment (disincentive) to the Contractor and no Qualified Hours as follows:

      Regardless of all prior partial payments for the Pay Item "Training", a correction equal
      to 100% of the Pay Item goal times the Pay Item price will be subtracted from the final
      payment due the Contractor on the Final Payment voucher.

      Example: Agency goal = 1,000 hours; Pay Item = $20.00/hr; Contractor achieves an
      actual 500 Qualified Hours (failed to meet the goal):                       therefore
      1,000 hours x $20.00/hr = line item deduction of $20,000 will show on the Final
      Payment voucher. If, as a result of this line item deduction, a net amount is due the
      Agency, the Contractor shall pay the Agency within 45 Calendar Days of notice of
      such deficiency.

Railway Property until the Contractor employed in connection with said work for ODOT shall
have executed and delivered to Railway an Agreement, in the form hereof, and shall have
provided insurance of the coverage and limits specified in said Contract and Section 2 of
this Agreement. If this Agreement is executed by other than the Owner, General Partner,
President or Vice President of Contractor, evidence is furnished to you herewith certifying
that the signatory is empowered to execute this Agreement for the Contractor.

Accordingly, as one of the inducements to and as part of the consideration for Railway
granting permission to Contractor to enter upon Railway Property, Contractor, effective on
the date of said Contract, has agreed and does hereby agree with Railway as follows:

Section 1 - RELEASE OF LIABILITY AND INDEMNITY

Contractor agrees to release Railway from any claims arising from the performance of this
Agreement which Contractor or any of its employees, subcontractors, agents or invitees
could otherwise assert against Railway, regardless of the negligence of Railway, except to
the extent that such claims are proximately caused by the intentional misconduct or gross
negligence of Railway.

Contractor shall indemnify and hold harmless Railway for all judgments, awards, claims,
demands, and expenses (including attorneys' fees), for injury or death to all persons,
including Railway's and Contractor's officers and employees, and for loss and damage to
property belonging to any person, arising in any manner from Contractor's or any of
Contractor's subcontractors' acts or omissions or failure to perform any obligation
hereunder. THE LIABILITY ASSUMED BY CONTRACTOR SHALL NOT BE AFFECTED


Union Pacific Railroad Company                                                     Page 9
(Exhibit C & C-1)
BY THE FACT, IF IT IS A FACT, THAT THE DESTRUCTION, DAMAGE, DEATH, OR
INJURY WAS OCCASIONED BY OR CONTRIBUTED TO BY THE NEGLIGENCE OF
RAILWAY, ITS AGENTS, SERVANTS, EMPLOYEES OR OTHERWISE, EXCEPT TO THE
EXTENT THAT SUCH CLAIMS ARE PROXIMATELY CAUSED BY THE SOLE
NEGLIGENCE OR SOLE WILFUL MISCONDUCT OF RAILWAY.

THE INDEMNIFICATION OBLIGATION ASSUMED BY CONTRACTOR SHALL INCLUDE
ANY CLAIMS, SUITS OR JUDGMENTS BROUGHT AGAINST RAILWAY UNDER THE
FEDERAL EMPLOYEE'S LIABILITY ACT, INCLUDING CLAIMS FOR STRICT LIABILITY
UNDER THE SAFETY APPLIANCE ACT OR THE BOILER INSPECTION ACT,
WHENEVER SO CLAIMED.

Contractor further agrees, at its expense, in the name and on behalf of Railway, that it shall
adjust and settle all claims made against Railway, and shall, at Railway's discretion, appear
and defend any suits or actions of law or in equity brought against Railway on any claim or
cause of action arising or growing out of or in any manner connected with any liability
assumed by Contractor under this Agreement for which Railway is liable or is alleged to be
liable. Railway shall give notice to Contractor, in writing, of the receipt or dependency of
such claims and thereupon Contractor shall proceed to adjust and handle to a conclusion
such claims, and in the event of a suit being brought against Railway, Railway may forward
summons and complaint or other process in connection therewith to Contractor, and
Contractor, at Railway's discretion, shall defend, adjust, or settle such suits and protect,
indemnify, and save harmless Railway from and against all damages, judgments, decrees,
attorney's fees, costs, and expenses growing out of or resulting from or incident to any such
claims or suits.

It is mutually understood and agreed that the assumption of liabilities and indemnification
provided for in this Agreement shall survive any termination of this Agreement.

Section 2 - INSURANCE

       to coverage for the following: (a) Bodily injury including death and personal injury;
       (b) Property damage; (c) Fire legal liability; (d) Products and completed operations.
       Where explosion, collapse, or underground hazards are involved, the X, C, and U

       WAIVER OF THE INSURANCE COMPANY'S SUBROGATION RIGHTS AGAINST
       Union Pacific Railroad Company.

        The following endorsements are included in the policy: a) "For purposes of this
        insurance, Union Pacific Railroad payments related to the Federal Employers


Union Pacific Railroad Company                                                       Page 10
(Exhibit C & C-1)
        Liability Act or a Union Pacific Wage Continuation Program or similar programs are
        deemed not to be either payments made or obligations assumed under any Workers
        Compensation, disability benefits, or unemployment compensation law or similar
        law." b) The exclusions for railroads (except where the Job Site is more than
        50 feet from any railroad including but not limited to tracks, bridges, trestles,

        insurance, Union Pacific Railroad payments related to the Federal Employers
        Liability Act or a Union Pacific Wage Continuation Program or similar programs are
        deemed not to be either payments made or obligations assumed under any Workers
        Compensation, disability benefits, or unemployment compensation law or similar
        law". b) The exclusions for railroads (except where the Job Site is more than

       least $500,000 each accident, $500,000 disease policy limit, $500,000 each
       employee.

        If Workers Compensation insurance will not cover the liability of Contractor in states
        that require participation in state workers' compensation fund, Contractor shall
        comply with the laws of such states. If Contractor is self-insured, evidence of state
        approval must be provided along with evidence of excess workers compensation
        coverage. Coverage shall include liability arising out of the U.S. Longshoremen's
        and Harbor Workers' Act, the Jones Act, and the Outer Continental Shelf Land Act,

        The policy shall also contain the following endorsement:         Alternate Employer
        Endorsement.

   (4) Umbrella or Excess Policies - In the event Contractor utilizes Umbrella or excess
       policies, these policies shall "follow form" and afford no less coverage than the
       primary policy.

   (5) Railroad Protective Liability insurance stating Union Pacific Railroad Company is
       the Named Insured covering all of the liability assumed by the Contractor under the
       provisions of this Agreement with coverage of at least $2,000,000 per occurrence

(Exhibit C & C-1)
        Seepage and Pollution Endorsement (see attached copy). A binder stating the
        policy is in place must be submitted to the Railroad until the original policy is
        forwarded to the Railroad.

   (6) Punitive damage exclusion must be deleted, which deletion shall be indicated on the
       certificate of insurance.

   (7) Contractor agrees to waive its right of recovery, and its insurers, through policy
       endorsement, agree to waive their right of subrogation against Railroad. Contractor
       further waives its right of recovery, and its insurers also waive their right of
       subrogation against Railroad for loss of its owned or leased property or property
       under its care, custody and control. Contractor's insurance shall be primary with
       respect to any insurance carried by Railroad. All waivers of subrogation shall be
       indicated on the certificate of insurance.

   (8) All policy(ies) required above (excluding Workers Compensation) shall provide
       severability of interests and shall name Railroad as an additional insured.
       Severability of interest and naming Railroad as additional insured shall be indicated
       on the certificate of insurance.

   (9) Prior to commencing the Work, Contractor shall furnish to Railroad original
       certificate(s) of insurance evidencing the required coverage, endorsements, and
       amendments. The certificate(s) shall contain a provision that obligates the
       insurance company(ies) issuing such policy(ies) to notify Railroad in writing of any
       cancellation or material alteration. Upon request from Railroad, a certified duplicate
       original of any required policy shall be furnished.

   (10) Any insurance policy shall be written by a reputable insurance company acceptable
        to Railroad or with a current Best's Insurance Guide Rating of A- and Class VII or
        better, and authorized to do business in the state(s) in which the service is to be
        provided.

   (11) Contractor WARRANTS that this Agreement has been thoroughly reviewed by
        Contractor's insurance agent(s)/broker(s), who have been instructed by Contractor
        to procure the insurance coverage required by this Agreement and acknowledges
        that Contractors insurance coverage will be primary.

   (12) If Contractor fails to procure and maintain insurance as required, Railroad may elect
        to do so at the cost of Contractor plus a 25% administration fee.

   (13) The fact that insurance is obtained by Contractor, or Railroad on behalf of
        Contractor, shall not be deemed to release or diminish the liability of Contractor,
        including, without limitation, liability under the indemnity provisions of this
        Agreement. Damages recoverable by Railroad shall not be limited by the amount of
        the required insurance coverage.

The average train traffic per 24 hour period on this route is 45 freight trains at a timetable
speed of 30 MPH and 0 passenger trains and (unknown) switch engine movements.

All insurance shall be placed with insurance companies licensed to do business in the
States in which the work is to be performed, and with a current Best's Insurance Guide


Union Pacific Railroad Company                                                       Page 12
(Exhibit C & C-1)
Rating of A- and Class VII, or better. In all cases except Workers' Compensation and
Railroad Protective Liability coverage the certificate must specifically state that Union
Pacific Railroad Company IS AN ADDITIONAL INSURED.

Any coverage afforded Railway, the Certificate Holder, as an Additional Insured shall apply
as primary and not excess to any coverage issued in the name of Railway.

Such insurance shall be approved by the Railway before any work is performed on
Railway's Property and shall be carried until all work required to be performed on or
adjacent to Railway's Property under the terms of the contract is satisfactorily completed as
determined by ODOT, and thereafter until all tools, equipment and materials not belonging
to the Railway, have been removed from Railway's Property and Railway Property is left in
a clean and presentable condition. The insurance herein required shall be obtained by the
Contractor and Contractor shall furnish Railway with an original certificate of insurance,
signed by the insurance company, or its authorized representative, evidencing the issuance
of insurance coverage as prescribed in (a) 1through 13 above, plus the original Railroad
Protective Liability insurance policy to:

Judi Scott, Risk Management, Insurance Group, Room 820, 1416 Dodge St., Omaha,
NE 68719. (402) 271-2215

The certificate of insurance shall guarantee that the policies will not be amended, altered,
modified or canceled insofar as the coverage contemplated hereunder is concerned,
without at least 30 days notice mailed by registered mail to Railway.

Full compensation for all premiums which the Contractor is required to pay on all             the
insurance described hereinafter shall be considered as included in the prices paid for        the
various items of work to be performed under the Contract, and no additional allowance         will
be made therefore or for additional premiums which may be required by extensions of           the
policies of insurance.

It is further distinctly understood and agreed by the Contractor that its liability to the Railway
herein under Section 1 will not in any way be limited to or affected by the amount of
insurance obtained and carried by the Contractor in connection with said Contract.

The Railway File reference number and ODOT Project information shown at the top of this
Agreement, must appear on any original insurance policies or certificates of insurance sent
to Railway by the Contractor.

Section 3 - The Contractor will observe and comply with all the provisions, obligations and
limitations to be observed by Contractor which are contained in the CONTRACTOR
REQUIREMENTS (Exhibit C), and shall include, but not be limited to, payment of all costs
incurred for any damages to Railway roadbed, tracks, and/or appurtenances thereto,
resulting from use, occupancy, or presence of its employees, representatives, or agents or
subcontractors on or about the construction site.

Section 4 - Contractor shall be responsible to Railway, including its affiliated railway
companies, and its tenants for all damages for any unscheduled delay to a freight or
passenger train that affects Railway's ability to fully utilize its equipment and to meet
customer service and Contract obligations. Contractor will be billed, as further provided
below, for the economic losses arising from loss of use of equipment and train service


Union Pacific Railroad Company                                                          Page 13
(Exhibit C & C-1)
employees contractual loss of incentive pay and bonuses, and contractual penalties
resulting from train delays, whether caused by Contractor, or subcontractors, or by the
Railway performing Railway Work as required by the project. Railway agrees that it will not
perform any act to unnecessarily cause train delay.

For loss of use, Contractor will be billed per freight train hour at an average rate of
($385.33 in 1997) with annual adjustments per hour per train as determined from Railway's
record. Any disruption to train traffic may cause delays to multiple trains at the same time
for the same period.

In addition to the above damages, passenger, U.S. mail trains and certain other grain,
intermodal, coal and freight trains operate under incentive/penalty contracts between
Railway and its customer. Under these arrangements, if Railway does not meet its contract
service commitment, Railway may suffer loss of performance or incentive pay or be subject
to a penalty payment. Contractor shall be responsible for any train performance and
incentive penalties or other contractual economic losses actually incurred by Railway which
are attributable to a train delay caused by Contractor, or subcontractors.

As example, a train arrives 30 minutes after its contract service commitments and Railway
is assessed damages per terms of the contract. Either Contractor, and/or subcontractors,
caused a 29 minute delay to the train and therefore are not responsible for any train
performance and incentive penalties or other contractual economic losses actually incurred
by Railway.

As example, a train arrives 30 minutes after its contract service commitments and Railway
is assessed damages per terms of the contract. Either Contractor, and/or subcontractors,
caused a 31 minute delay to the train and therefore are 100% responsible for any train
performance and incentive penalties or other contractual economic losses actually incurred
by Railway.

The contractual relationship between Railway and its customers is proprietary and
confidential. In the event of a train delay covered by this Agreement, Railway will share
information relevant to any train delay to the maximum extent consistent with Railway
confidentiality obligations. Damages for train delay for certain trains could be as high as
$50,000.00 per incident.

Contractor and subcontractors shall plan, schedule, coordinate and conduct all Contractor's
work so as to not cause any delays to any trains.

damaged concrete, unconsolidated concrete and surface laitance with a high pressure
washer conforming to 00540.28 to the extent that clean aggregate (free of surface mortar)
is exposed on 50% of the surface. Clean the joint surface again immediately prior to the
concrete placement to remove any subsequent deposits of dirt, debris or other foreign
materials. Saturate the joint surface with potable water immediately before resuming
concrete placement. Remove standing water in depressions or hollows of the joint surface.

Saw cut the top 1 inch of the deck joints with a straight vertical cut before subsequent
concrete placement and before saturating the surface with water. Where joints are straight
and without spalls, the Engineer may waive this saw cut requirement.

         QPL. The quantity of each admixture to be used shall be determined by trial
         batches prior to its use in MC produced for the Project. This quantity may have to
         be adjusted in actual field use to obtain the properties specified in 00559.14. Each
         chemical admixture shall be added to the MC mix according to the manufacturer's
         recommendations.

    (b) New Mix Designs - New mix designs are those which have not been used
    previously or do not meet the requirements of 00559.13(c) for current mix designs.
    Make as many trial batches of any size as necessary, but the final trial batch of the
    same material and mix design that is to be used on the Project must be a minimum
    of 2 cubic yards mixed in a truck mixer. Prepare and test the trial batch by casting,
    curing, and testing cylinders for compressive strength.

         (1) Plastic MC - Test the slump, unit mass (weight), and air content and compute
         the water-cement ratio and cement content for each trial batch. Slump, air content
         and water-cement ratio must be within specification limits and be representative of
         what will actually be used in the job for the trial batch to be valid.

         (2) Strength Tests - Cast at least three 6 inch x 12 inch or three 14 inch x 8 inch
         cylinders for each mix design and test at 7 days. Cast the cylinders in single-use
         plastic molds. All strength specimens shall be cast and cured in accordance with
         AASHTO T 23 or AASHTO T 126. Test the cylinders for compressive strength
         according to AASHTO T 22.

         (3) Required Strength - The average -day compressive strength of the trial batch
         cylinders must exceed the following:

                                          Specified Strength x 1.20

    (c) Current Mix Designs - A current mix design which has been used in any previous
    project, public or private within one year before actual date of use on this Project. The
    mix design must meet the tolerances and limits in 00559.14 and the average of all
    7-day strength tests must exceed the required strength as follows:

                        Required Strength = Specified Strength + 1.34S

                        Where S = Standard Deviation of 7-day cylinder strengths

    If these requirements are not met, submit a new mix design according to 00559.13(b).

    (d) Review of Mix Designs - Submit each mix design proposed for use for review with
    the information required in 00559.13(e) or 00559.13(f). Do not proceed with MC
    placement using the mix design until the Engineer has determined that it complies with

                   •    Record all information needed to compute the water-cement ratio of all
                        loads of concrete delivered to the Project.

                   •    Perform mix temperature, air content, slump, and yield tests whenever a
                        set of cylinders is cast by the Engineer.

         (2) Records - All tickets, water-cement ratio calculations, and all other records
         required by 00559.15(b) shall be delivered to the Engineer upon availability but no
         later than one hour after the end of the shift.

00559.16 Acceptance Sampling and Testing - Perform acceptance sampling and testing
according to the following:

    (a) Compressive Strength - One set of three cylinders shall be cast by the
    Contractor’s QCT from each 50 cubic yards of MC placed on the Project. A minimum of
    one set shall be cast per production shift. The MC shall be sampled according to
    WAQTC TM 2. The test cylinders shall be cast and cured according to AASHTO T 23,
    using 6 inch x 12 inch or 4 inch x 8 inch single-use plastic molds. If a new mix design
    was submitted according to 00559.13(b), use the same size cylinders as were used for
    testing the new mix design. Test the cylinders cast by the Contractor’s QCT at an
    accredited lab for compressive strength at seven days. The average strength of the
    three cylinders will constitute the test result. Provide test results to the Engineer within
    24 hours after the seven-day break. Remove and replace material represented by a
    test result of less than 3,600 psi at no additional compensation, unless the Engineer
    determines the material can be left in place at a reduced price.

    (b) Surface Tolerance - The finished work, when tested with a 12 foot straightedge,
    shall not vary from the testing edge by more than 1/4 inch at any point. Furnish the

    straightedge and operate it under the direction of the Engineer. If the MC does not
    conform to the prescribed limits of deviation, the operations shall be stopped until
    revised methods, changes in equipment, or correction of procedures are proposed, and
    are approved by the Engineer for trial. The revised operation shall also be stopped if it
    does not produce a surface complying with specified requirements.

    Correct all nonspecification surface tolerance with a self-propelled diamond grinder and
    retexture the surface with a diamond saw to match requirements of 00559.42(e-4), first
    bullet, at no additional cost to the Agency, including required traffic control.

    (c) Bond - Cut cores and conduct bond tests on all cores. The Engineer will analyze
    the tests as required by this subsection. Restore the area voided by the cores by air
    blowing, wetting, and then filling with MC or an approved product. Cost of cutting the
    cores, making the bond tests, and restoring the deck or pavement shall be borne at no
    additional compensation except as provided in 00559.43.

    (d) Bond Test - Make two satisfactory bond tests per pour in the presence of and at
    locations designated by the Engineer prior to opening to traffic and within 28 days of
    placement. The tests shall consist of coring through the MC overlay and about 1 inch
    into the existing concrete, attaching a device to the top of the core, and exerting a
    tensile load to the core sufficient to cause failure. Bond strength of the test core less
    than 100 psi will be considered unsatisfactory. All cores shall be pulled to failure or
    200 psi, whichever occurs first.

                   placement. The deck surface temperature shall be forecast to remain less
                   than 65 °F for the duration of the entire pour.

              •    The air temperature is at least 45 F at the start of MC placement and is
                   forecast to remain above 45 F and less than 80 °F for eight consecutive
                   hours after the pour is completed.

              •    Wind at the site measured within 24 inches above the deck surface on the
                   centerline of pavement is less than 15 mph at the start of MC placement and
                   is forecast to remain under 15 mph for duration of placement. If the wind
                   increases during placement to 15 mph or above, placement shall stop,
                   unless wind breaks or other methods are used to control the wind across the
                   surface of the MC being placed.

              •    It is not raining.

              •    During the hours of darkness, work areas are illuminated.           Submit the

    Protect fresh deck concrete from vibration and deflection for a minimum of 72 hours
    after application of the last curing coverings, as follows: Do not allow vehicle traffic or
    Contractor's equipment, on the fresh concrete. Do not perform any work that would
    impart vibrations or deflection to the fresh concrete.

    When traffic is allowed in the lane(s) adjacent to the pour, it shall be slowed by flaggers
    for at least four hours after completion of the pour. The Engineer may direct that the
    time be increased because of weather or traffic conditions.

    (e) Placement Procedures - Furnish a minimum of two transverse work bridges, not
    counting the finishing machine.

         (1) Preceding Placement - The finishing machine shall be test run in the presence
         of the Engineer over the deck or pavement before each day's paving to insure the
         required thickness of MC overlay will be achieved. MC shall be placed working
         down-grade, unless otherwise approved by the Engineer.

         (2) Joints - At transverse and longitudinal joints, saw the surface course previously
         placed to a straight, vertical edge before placing the adjacent course. Sawing of
         joints may be omitted if the bulkhead produces a straight, smooth, vertical surface.
         The face of the joints whether sawed or formed shall be sand- or water- blasted to
         remove loose material.

              a. Longitudinal Joint - A longitudinal construction joint will be permitted only at
              the centerline of the roadway or at lane lines unless otherwise shown or
              directed.

              b. Transverse Joint - In case of delay in the placement operation exceeding
              one-half hour in duration, form a construction joint by removing all material not
              up to finish grade and sawing the edge in a straight line. Further placement is
              permitted only after the requirements of 00559.42(e-5) have been met, unless a
              12 foot gap is left between placements. During minor delays of one-half hour or
              less, protect the end of the placement from drying with several layers of wet
              burlap.

         (3) Placing - Place MC only on surfaces prepared according to 00559.41(b).

         Place longitudinal deck pours shown in a continuous pour from one transverse deck
         joint to another.

         All placement operations shall stop if it starts to rain. Protect fresh previously placed
         MC from rain. The Engineer may order removal of any MC damaged by rain.

         (4) Roadway Finish - After the roadway has been struck off with a finishing
         machine conforming to 00559.21(d-1), mist the surface horizontally with water and
         float it, if necessary, to produce a uniform tight texture. Do not spray water directly
         on the freshly placed concrete and do not allow water to puddle or pond. Quality of
         workmanship shall be such that the finished work meets the tolerances of
         00559.16(b).

         In the bullet that begins "Provide high pressure washers…", replace the sentence
         beginning "Apply fog spray…" with the following sentence:

              Apply fog spray upwind of the concrete placement during finishing and texturing,
              and until the cure has been applied.

         Replace the bullet that begins "Cover the concrete…" and its two sub-bullets with
         the following bullet:

                  Cover the concrete with a single layer of clean initial covering immediately
                   after finishing, texturing, and applying an evaporation reducer. Apply initial
                   covering no later than 20 minutes after the final pass of the finishing machine
                   and no farther than 20 feet from the back of the finishing machine. Provide
                   an initial covering with a minimum length sufficient to cover the bridge deck
                   from side to side of the concrete placement. Use non-woven, needle
                   punched polypropylene fabric curing blanket from the QPL. Place wet or
                   dry. Dry-placed fabric shall be wetted by fogging within 15 minutes of fabric
                   placement. All overlaps shall be a minimum of 12 inches.

period, the surface will be checked for cracks. If cracks are found, cores may be required.
The cost of coring will be paid as Extra Work. If cracking is determined to have been
caused by the Contractor's placing or curing methods, the cost of coring will be borne by
the Contractor.

Seal all visible cracks with a methacrylate sealer or epoxy sealer from the QPL unless the
Engineer determines removal and replacement are required.

In areas where the cracks are numerous or are less than 6 inches apart, flood the entire
area with methacrylate or an epoxy sealer from the QPL. Cover the sealer with a dry,
washed sand, prior to the sealer setting.

The surface will also be surveyed by the Engineer for delaminations, bond failure, or other
damage by use of a chain drag and coring or other suitable device. Areas of delamination
of less than 1 square foot do not require repair. The cost of any core with a bond strength
of less than 100 psi will be borne by the Contractor. The cost of any coring, except those
required in 00559.16(d), with a bond strength of 100 psi or greater will be paid as Extra
Work.

All corrective measures, including cutting, removing, preparing, replacing nonspecification
material, and filling of core holes, as required in 00559.16, will be at no additional
compensation. All corrective measures shall be completed before opening to traffic, unless
otherwise directed by the Engineer. If the resurfaced area is opened to traffic at the
Contractor's request prior to completion of the above items, all additional traffic control to
complete those items will be at no additional compensation.
