ADDENDUM NO. 1

SECTION 1.08 - PROSECUTION AND PROGRESS

Article 1.08.03 – Prosecution of Work:

Add the following:

The project will be constructed in various phases as described herein.

Phase I – Organization Phase up to (45) Calendar Days.

The first phase is to afford the Contractor time for the administrative/engineering/procurement

function required for the project. This would include such items as performing construction

staking, digging test pits, submitting catalog cuts or shop drawings and purchasing materials.

Actual construction is not permitted during the phase 1 unless approved by the Engineer. The

Contractor is to use this time to fully prepare for the successive phases so that construction can

proceed quickly and efficiently. During the phase, after the construction staking is complete and

underground utilities are marked out the Contractor, the designer and the Engineer will walk the

project to determine if there are test pits necessary or if there are any apparent conflicts with

private property, utilities, or other roadside appurtenances such as obstructions, rocks, large

trees, etc. Those conflicts will be resolved prior to ordering equipment for the specific area

where the conflict exits.

Phase 2 – Construction Phase

Phase 2 will not start prior to the conclusion of Phase 1, without the written permission of the

Engineer.

When all apparent conflicts have been identified and resolved, and written commitments have

been received from suppliers that all equipment and materials will be received within 30 days,

the Contractor may request that the construction phase begin. Once commencement of

construction begins, as and when approved by the Engineer, the Contractor will have the

remaining contract calendar days to complete the work, including cleanup. That work, once

started, must be completed within the time established for the original contract and liquidated

damages, as specified elsewhere in the Contract, will be assessed against the Contractor per

calendar day from that day until the date on which the work is complete. If unforeseen situations

arise, the Contractor may request an extension of time for an individual location and, if justified,

the Engineer may grant an extension of time for that location. Granting an extension of time for

one location will not entitle the Contractor to extensions of time for other locations in the project.

Section 1.08

ADDENDUM NO. 1

New Work

Additional work, including work at a separate location, may be added to the contract in

accordance with Article 1.04.05 of the Standard Specifications. This work may result in contract

extension, which would require an organization phase and a construction phase for the new

location. If a contract extension is granted for the additional work, liquidated damages for this

portion of the work will be negotiated with the Contractor. Such an extension of time would not

affect the time allowed for the original work in the contract. Original work, once started must be

completed within the original construction phase, and liquidated damages will be assessed for

any days beyond that phase which the Contractor takes to complete the original work.

Traffic Signal Work

The Contractor will not be allowed to install traffic signal or pedestrian heads until the

controllers are on hand and ready for installation. Once installation of this equipment

commences, the Contractor shall complete this work in a most expeditious manner.

The Contractor shall notify the project engineer on construction projects, or the district permit

agent on permit jobs, when all traffic signal work is completed. This will include all work at

signalized intersections including loop replacements, adjusting existing traffic signals or any

relocation work including handholes. The project engineer or district permit agent will notify the

Division of Traffic Engineering to coordinate a field inspection of all work. Refer to Section

10.00 – General Clauses For Highway Illumination And Traffic Signal Projects, Article 10.00.10

and corresponding special provision.

The Contractor shall notify the Traffic Signal Lab at Telephone (860) 258-0346 or (860) 258-

0349 forty five (45) days prior to starting work on computer controlled signalized intersections

only. This notice will initiate work to be completed by others. The Contractor shall be

responsible for any timely updates that need to be reported to this Unit for the successful

coordination of work by others.

courses if present, by approved methods. The existing base material shall remain in place unless

additional excavation is required to achieve final pavement grades. In the event that the Contractor

performs additional excavation that has not been approved by the Engineer or that has been

determined by the Engineer to be in excess of that which is necessary to achieve the proposed

grades, the Contractor shall replace this excavated material with materials approved by the

Engineer at no cost.

Processed Materials

If additional materials are required to supplement the existing base so to meet final grades, they

shall be new processed aggregate and shall be placed and uniformly graded and compacted.

The pavement removal operation shall be conducted so as not to permit the contamination of the

existing base material with any shoulder debris including, grass, leaves or dirt.

Weather Limitations

Work on the structurally sound base course shall not be permitted when temperatures are less than

35 degrees F nor when the subgrade is frozen or excessively wet to the extent that the existing

materials are unstable in a saturated condition. The Contractor at his/her cost shall repair any

damage resulting to the base course for any reason, which is attributed to his/her negligence, as

determined by the Engineer.

Grading & Compacting

The base materials shall be uniformly graded and compacted to the lines and grades specified on

the plans or as established by the Engineer. Areas of special cross slope shall be compacted by

beginning at the lowest edge and proceeding towards the higher edge. The Contractor will be

required to have dust control equipment available on-site until such time that the base has been

properly compacted and paved.

Transitions

Driveway, sidewalk, pedestrian ramp and intersecting street transitions are to be maintained for

public use at all times during this operation. Millings, cold patch or hot patch shall be ramped in

order to safely accommodate residential driveways or sidewalk and ramps for public access. Cold

or hot patch shall be ramped in order to safely accommodate commercial driveway public access

or intersecting streets.

FINISHING

Tolerances

The final surface of the base course shall be fine graded so that, after final compaction and just

prior to placement of the HMA course, the surface elevation shall not vary more than one-half

(1/2) inch above or below the design line and grade at any location. If after approval, the base

course becomes displaced or disturbed in any way for any reason, the Contractor shall repair the

damage then regrade the base. All repaired sections shall be recompacted until they meet the

requirements of this specification.

Compaction

The base materials will be thoroughly compacted with roller(s) to produce a minimum of ninety-

five (95) percent compaction and uniform base density when compared to the Modified Proctor

Test, (AASHTO T180). The in-place field density shall be determined in accordance with ASTM

D1556, D2167, or ASTM D2922. If the specified density is not attained, the entire area shall be

reworked and/or recompacted and two additional random tests made. This procedure shall be

followed until the specified density is reached. Water may need to be applied to ensure optimum

moisture content during compaction and to aid in achieving maximum compaction.

UNSUITABLE MATERIAL

Dust Control

This section requires controlling dust generated as a result of work under this item. The Contractor

is responsible for controlling dust at all times, including nonworking hours, weekends, nights, and

holidays. Dust control procedures shall be conducted when particulate matter concentrations

exceed the National Air Quality Standard of 150 micro-grams/m3 on a 24 hour average basis or as

designated by the Engineer. Wet suppression shall consist of applications of water, or a wetting

agent in solution with water if approved by the Engineer. Wet suppression equipment shall consist

of sprinkler pipelines, tanks, tank trucks, or other devices capable of providing regulated flow,

uniform spray, and positive shut-off. Water will be spread at a uniform rate of 1.0 gal./s.y. and

when wetting agents are used they will be added at the manufacture’s recommended rates.

Wetting agents for dust suppression shall be water soluble, nontoxic, nonreactive, nonvolatile, and

nonfoaming. Calcium chloride shall NOT be used to control dust.

Dust control operations do not relieve the Contractor of compaction requirements.

Cobbles

Any exposed cobbles greater than three and one half (3-1/2") inches in diameter within the

pavement area shall be "culled-out" and wasted as directed by the Engineer. Payment for this work

shall be incidental to this bid item and it will be the responsibility of the Contractor to dispose of

ITEM #2999998A – ON-THE-JOB TRAINING PROGRAM

This On-The-Job Training Program Special Provision supersedes Section 7b of the Required Contract Provision entitled “Specific Equal Employment Opportunity Responsibilities”, as amended, and is included in this contract in implementation of Title 23 U.S.C. Section 140(a) as established by Section 22 of the Federal-Aid Highway Act of 1968.

As part of the Contractor's equal employment opportunity affirmative action program, on-the-job training shall be provided as follows:

The Contractor shall provide on-the-job training aimed at developing and retaining full journeypersons in the type of trade involved. The number of trainees or apprentices to be trained under this Contract is determined by dividing the original quantity of hours assigned in the proposal form by 1,000 hours, or the number of hours required under a particular apprenticeship program schedule. In the event the Contractor subcontracts a portion of the contract work, he shall determine how many, if any, of the trainees are to be trained by the subcontractor, provided however, that the Contractor shall retain the primary responsibility for meeting the training requirements imposed by this provision. The Contractor shall also ensure that this On-the-Job Training Special Provision is made applicable to such subcontract.

The Contractor shall submit for approval to CDOT a training outline for each trainee or apprentice that will be trained on this project. The training outline shall include the trade, the training categories, the number of training hours that will be provided, and if there will be any off-site training. If the Contractor is participating in a bona fide apprenticeship program approved by the Connecticut State Labor Department (CDOL) Apprentice Training Division, identification of such apprentice program shall also be submitted to CDOT.

Training, upgrading and retaining minority group workers and women in the various construction trades is a primary objective of this Training Special Provision. This training commitment is not intended, and shall not be used, to discriminate against any applicant for training, whether a member of a minority group or not. Contractors are encouraged to conduct outreach to those individuals interested in employment opportunities on this project.

Accordingly, a Contractor choosing to utilize a non-apprenticeship program shall make use of the supportive services consultant and/or make every effort to enroll minority and women trainees or apprentices by conducting systematic and direct recruitment through public and private sources likely to yield minority and women trainees to the extent such persons are available within a reasonable area of recruitment. The Contractor will be given an opportunity and will be responsible for demonstrating the steps that he has taken in pursuance thereof; prior to a determination as to whether the Contractor is in compliance with this Training Special Provision.

0063-0633 125

No employee shall be employed as a trainee or apprentices in any classification in which he/she has successfully completed a training course leading to journeyperson status or in which he/she has been employed as a journeyperson. Trainees, or apprentices, may be employed and trained in the advancement of their training or apprenticeship program.

After award of the Contract, and prior to the order to start date of the physical construction of the project, the Contractor shall, in conjunction with the required schedule of progress or time chart, submit and, obtain approval for, the number of trainees, or apprentices, for each classification selected, the training outline for each classification and an explanation of the start time of each trainee as it relates to the schedule of progress or time chart.

The minimum length and type of training for each classification will be as established in the training program selected by the Contractor and approved by CDOT and the FHWA. The CDOT and the FHWA shall approve a program if it is reasonably calculated to meet the equal employment opportunity obligations of the Contractor and to qualify the average trainee or apprentice for journeyperson status in the classification concerned by the end of the training period. Furthermore, programs approved by the U.S. Department of Labor (USDOL) or CDOL, including apprenticeship programs, shall be considered acceptable under this On-the-Job Training Program Special Provision, except in those cases where the Secretary of Transportation, the Federal Highway Administrator, or CDOT, has determined that the program is not administered in a manner consistent with the equal employment obligations of Federal-aid highway construction contracts.

The Contractor shall furnish each trainee or apprentice with a copy of the program that will be followed in providing the training. The Contractor shall provide each trainee or apprentice with a certification showing the type and length of training satisfactorily completed.

The Contractor shall provide for the maintenance of records and furnish monthly and final reports documenting his performance under this On-the-Job Training Special Provision to the Engineer. The monthly updates and final report shall be made on forms provided by CDOT or by providing signed copies of the “Apprentice Handbook and Progress Record” provided by CDOL.

In the event that the Contractor intends to transfer a trainee or apprentice to another CDOT, (FHWA funded) project, the Contractor shall provide CDOT with a minimum of a 14-day advance notice.

Except as otherwise noted below, the Contractor will be reimbursed at $1.00 per hour of training given an employee in accordance with an approved training or apprenticeship program. As approved by CDOT, reimbursement will be made for training hours in excess of the number specified. This reimbursement will be made even though the Contractor receives additional training program funds from other sources, provided such

0063-0633 126

other source does not specifically prohibit the Contractor from receiving other reimbursement.

Payment for training is made upon completion of the training program on this Contract and not on a monthly basis.

No payment shall be made to the Contractor if either the failure to provide the required training, or the failure to hire the trainee as a journeyperson, is caused by the Contractor. It is normally expected that a trainee or apprentice will remain on the project as long as training opportunities exist in his work classification or until he has completed his training program. It is not required that all trainees or apprentices be on board for the entire length of the Contract. A Contractor will have fulfilled his responsibilities, under this On-the-Job Training Special Provision, if he has provided acceptable training for the number of hours specified.

Trainees will be paid at least 60 percent of the appropriate minimum journeyman's rate specified in the Contract for the first half of the training period, 75 percent for the third quarter of the training period, and 90 percent for the last quarter of the training period, unless apprentices or trainees in an approved existing program are enrolled as trainees on this project. In that case, the appropriate rates approved by the Department of Labor in connection with the existing program shall apply to all trainees or apprentices being trained for the same classification who are covered by this On-the-Job Training Program Special Provision.

The number of hours shown on the proposal form for Item #2999998A On-The-Job Training Program is not to be altered in any manner by the bidder. Should the bidder alter the amount shown, the altered figures will be disregarded and the original quantity will be used to determine the amount bid for the contract.
