ADDITIONAL PROVISIONS FOR UTILITIES CONTRACTORS SECTION 800

SECTION 800

ADDITIONAL PROVISIONS FOR UTILITIES CONTRACTORS

PART 1 – GENERAL

1.01 DESCRIPTION

The additional provisions in this section apply to work on Utilities Capital Improvement Projects

(CIP).

1.02 DEFINITIONS

Capitalized terms which are not otherwise defined in these Standards have the same meaning provided in Article 1 of the City’s General Conditions.

1.03 COST SAVINGS INCENTIVE

The Contractor may suggest contract cost savings changes by means of a contract cost savings proposal (CCSP). If these changes are approved by the City as deductive change orders, the contract cost savings shall be shared by the Contractor and City, as long as the proposed change is of equal or greater performance that meets the original design’s performance goal(s). The sharing of cost savings shall be 50 percent to the Contractor and 50 percent to the City. The City's cost for reviewing the Contractor's suggested savings shall include the cost of engineering services for evaluation of proposals and cost of required redesign. The City's total cost for all reviews of Contractor proposals shall be deducted from the total cost savings to be shared.

The Contractor may suggest savings at any time during the contract period. The Engineer will evaluate Contractor-suggested cost savings and the City will make a decision as to whether or not to make the change.

At a minimum, the Contractor shall include in each CCSP the following information:

A. A description of the difference between the existing contract requirement and the proposed change. The comparative advantages and disadvantages of each, a justification of the alteration of an item's function or characteristics, and the effect of the change on the item's performance.

B. A list and analysis of the contract requirements that must be changed if the CCSP is accepted, including any suggested revisions to the project specifications.

C. A separate, detailed cost estimate for (a) the affected portions of the existing contract requirement and (b) the CCSP shall be submitted. The cost reduction associated with the CCSP, shall take into account the Contractor's development and implementation costs as set forth in the City Standard Drawings and Specifications, including any amount attributable to subcontracts.

D. A statement of the time by which a contract modification accepting the CCSP must be issued in order to achieve the maximum cost reduction, noting any effect on the contract completion time or delivery schedule.

CITY OF PALO ALTO Section 800

The Engineer will process CCSP's expeditiously, however, in no case will a deductive change order, proposed during the time period or later in the project, be the basis of a time extension.

If the CCSP is not accepted, the Engineer will notify the Contractor in writing, explaining the reasons for rejection. The Contractor may withdraw any CCSP, in whole or in part, at any time before it is acted upon by the Engineer.

1.04 TYPICAL TIMELINE AND CONTRACTOR REQUIREMENTS FOR NOTICE OF AWARD,

CONTRACT EXECUTION, NOTICE TO PROCEED, PRE-CONSTRUCTION SUBMITTALS, PRE-

CONSTRUCTION CONFERENCE, AND COMMENCEMENT OF WORK

F. The commencement of work date is anticipated to be 10 days after the pre-construction conference, when pre-construction submittals are substantially or completely approved.

1.05 SUBMITTALS

In addition to complying with the general submittal requirements in Section 3.12 of the General Conditions, Contractor must meet any specified project milestones by submitting required pre-construction submittals in advance to avoid delays due to submittal review or material lead time.

As further specified in Section 6.4 of the Construction Contract, liquidated damages may be assessed if the Contractor fails to meet specified project milestones. All pre-construction submittals must be approved prior to delivery of the material/equipment to the job site that the submittal relates to or starting the portion of work. Unless specifically stated elsewhere in the Contract Specifications, the Contractor shall make submittals in advance of ordering the materials to provide sufficient time for review, approval, possible revisions and re-submittals, and placing orders/securing delivery.

Ultimate responsibility for the accuracy and completeness of the information contained in each

CITY OF PALO ALTO Section 800 PAGE 2 submittal shall remain with the Contractor. Unless otherwise specified, make submittals in groups containing all associated items to assure that required information is available for checking when the submittal is received. Partial submittals may be rejected as not complying with the provisions of the Contract and the Contractor may be held liable for delays so occasioned. The Engineer will supply a checklist of items that shall be submitted by the Contractor for approval.

If the submittal is returned to the Contractor marked "NO EXCEPTIONS TAKEN", "MAKE CORRECTIONS NOTED", or “RECEIPT ACKNOWLEDGED”, formal revision and resubmission of the submittal will not be required. Fabrication of any item shall not commence before the Engineer has reviewed the pertinent submittals and returned copies to the Contractor marked "NO EXCEPTIONS TAKEN" or “MAKE CORRECTIONS NOTED.”

If the submittal is returned to the Contractor marked "REVISE AND RESUBMIT" or "REJECTED", the Contractor shall, within five (5) business days, make a complete and acceptable submittal to the Engineer by the second submission of a submittal item. When material is resubmitted for any reason, transmit under a new letter of transmittal and with a new transmittal number; on re-submittals, cite the original submittal number for reference.

Revisions indicated on submittals shall be considered as changes necessary to meet the requirements of the contract and shall not be taken as the basis of claims for extra work. If the Contractor considers any required revision to be a change, he shall so notify the Engineer as provided for in the General Conditions.

The Contractor shall maintain an accurate submittal log for the duration of the Work, showing current status of all submittals at all times, and keep it available to the Engineer for his review upon request.

Where contents of submitted literature from manufacturers include data not pertinent to the submittal, clearly show which portions of the contents are being submitted for review.

The Engineer's review of the Contractor's submittals shall not relieve the Contractor of the entire responsibility for the correctness of details and dimensions. The Contractor shall assume all responsibility and risk for any work not conforming to the contract. Any fabrication or other work performed in advance of the receipt of approved submittals shall be entirely at the Contractor's risk and expense.

1.06 MEETINGS

A. Pre-Construction Conference/Meeting

City will conduct a mandatory pre-construction meeting when pre-construction submittals are substantially or completely approved, typically 20 business days after the pre-construction submittal due date.

POLICY AND PROCEDURES FOR WATER USE SECTION 870

SECTION 870

POLICY AND PROCEDURES FOR WATER USE

PART 1 - GENERAL

1.01 GENERAL

Reclaimed water shall be used for backfill compaction, and cleaning and testing of manholes. An overhead standpipe with a five hundred (500) gallon per minute (gpm) fill rate is available at the Palo Alto Regional Water Quality Control Plant (RWQCP) between Monday through Friday, 6:30 a.m. to 5:00 p.m., except on public holidays. A recycled hydrant is also available for 24-hours a day, 7-days a week to active permit holders and is located at Greer Park, near 1198 Colorado Avenue, Palo Alto, CA. This will allow self-service pickup and use of reclaimed water on a first come-first serve basis, up to the capacity of the reclamation plant of four and a half (4.5) million gallons per day (MGD).

The permit may be obtained on the City’s website at:

https://www.cityofpaloalto.org/files/assets/public/public-works/water-quality-control-plant/recycled-water/2021/9.-user-guidelines-and-application.pdf and shall be submitted to the RWQCP at 2501 Embarcadero Way, Palo Alto, CA with a $50 check or money order payable to the “City of Palo Alto”. For additional information, call 650.329.2598 or e-mail recycledwater@cityofpaloalto.org

City Contractors are required to provide their company’s Certificate of Liability Insurance as part of the requirements for applying for a permit to claim recycled water. Applicants can request a multi-year permit for multi-year projects for the City of Palo Alto. Permits for recycled water expire every year end (December 31st) regardless of application date except for multiyear permits.

The City of Mountain View operates reclaimed water-filling hydrants at the end of Crittenden Lane (E.

of N. Shoreline Boulevard), and at Marine Way near Coast Avenue in Mountain View, CA. A key deposit is required. Contact the City of Mountain View at (650) 903-6329 or at recycledwater@mountainview.gov

Potable water for drinking, filling of water mains, etc. is available from hydrants in the vicinity of the work. Hydrant water shall be metered with a hydrant meter obtained by contacting the City of Palo Alto Utilities Business Office at (650) 329-2161 (Ground Floor Civic Center, 250 Hamilton Avenue, Palo Alto). A meter deposit is required. Payment for potable water used will be deducted from the Contractor's deposit at the time the meter is returned. Refer to the Policy and Procedures for Water Hydrant Meter Use, for more information.

All costs and expenses for any water used on the project shall be included in one or more of the Bid items and no extra compensation shall be paid to the Contractor for water.

PART 2 - POLICY AND PROCEDURES FOR WATER HYDRANT METER USE

2.01 USE RECLAIMED WATER WHENEVER POSSIBLE

The water consumption ordinance for the City of Palo Alto requires the review of water use for construction purposes, to encourage the use of reclaimed water. The use of a reasonable amount of potable water, for flushing potable water pipes, for instance, is still permissible through hydrant meters. However, substantial water needs for construction purposes must be met with reclaimed water.

Reclaimed water will be required for the following projects:

CITY OF PALO ALTO Section 870 https://www.cityofpaloalto.org/files/assets/public/public-works/water-quality-control-plant/recycled-water/2021/9.-user-guidelines-and-application.pdf https://www.cityofpaloalto.org/files/assets/public/public-works/water-quality-control-plant/recycled-water/2021/9.-user-guidelines-and-application.pdf mailto:recycledwater@cityofpaloalto.org mailto:recycledwater@mountainview.gov

1. Grading projects, i.e. road construction, paving, site development, and projects reviewed by the Water/Gas/Wastewater Division.

2. Street washing and flushing for final project clean-up.

3. Projects for which daily water use exceeds 5,000 gallons.

4. Projects for which weekly water use exceeds 25,000 gallons.

Procedures for permission to connect to City of Palo Alto hydrants and the penalties for not using the hydrant meter properly are explained below.

Exceptions to this policy typically are granted only for very small jobs. Requests for exceptions to this policy will be referred to the Senior Engineer in the Water/Gas/Wastewater Division for review and determination.

2.02 HOW YOU CAN GET A HYDRANT METER

Applicants for a water hydrant use permit should come in person to the Utilities Department Customer Service Center, 250 Hamilton Avenue, Ground Floor. At that time:

1. Complete a questionnaire about your project and its location.

2. Pay the $750 meter deposit fee.

3. Get six meter reading cards. NOTE: On or before the 25th day of each month, a card should be completed with the current meter reading and sent to the Customer Service Center.

4. You will then be given a form to take to the Municipal Services Center (MSC) at 3201 East Bayshore Road where you may pick up a hydrant meter. You will be assigned the meter for a period of six (6) months. At the end of that time the meter must be returned to the MSC. If you need potable water for the same project site after the three months, a new meter will be issued. Included with the hydrant meter will be an instruction sheet for proper use of the meter. By taking the meter, it is assumed that you will properly use the meter at all times when connecting to City hydrants.

2.03 PENALTIES

By providing an applicant with hydrant meters for use of potable water at construction sites, the City of Palo Alto is entering into a relationship of trust with the applicant. Nevertheless, City staff will, from time to time, visit the site to ensure that the hydrant meter is being used and that it is being used correctly. Failure to comply with any of the above rules or to properly hook up the meter according to the instruction sheet provided with the hydrant meter, may subject the applicant to penalties.

Specifically:

A. Failure to use the hydrant meter or to use it so that water does not pass through the meter when drawing water from a City of Palo Alto hydrant will result in fines of $50.00 per day and possible forfeiture of all or part of the deposit, revocation of the permit, and prosecution according to the law (Rule and Regulation 21.D.1.b.i; 21.D.1.b.iv; and 8.C.1-2).

B. Failure to submit meter-reading cards monthly and in a timely manner may result in forfeiture of

CITY OF PALO ALTO Section 870 PAGE 2 all or part of the deposit.

C. Failure to return the hydrant meter at the end of the three-month period may result in fines of $50.00 per day and/or part of the deposit.

CITY OF PALO ALTO Section 870 PAGE 3

"SPECIAL WATER UTILITY REGULATIONS, Rule and Regulation 21, Paragraph B. 1, B. 3."

Failure to return the hydrant meter at the end of the appropriate period may result in additional charges of $ 50.00 per day.
