3. All information relative to Contractor’s sole responsibilities and of means, methods, techniques, sequences and procedures of construction and safety precautions and programs incident thereto.
G. Contractor’s submission to City or to Engineer of a Shop Drawing or Sample submittal will constitute Contractor’s representation that it has satisfied its obligations under the Contract Documents, and as set forth immediately above, with respect to Contractor’s review and approval of that submittal.
H. Designation of work “by others”, if shown in submittals, shall mean that work will be responsibility of Contractor rather than subcontractor or supplier who has prepared submittals.
I. The Contractor shall sign a statement with each submittal, certifying that the submittal has been checked by the Contractor and is in conformance with the Specifications. Any submittal received without this certification shall be returned AMEND AND RESUBMIT and count as one submittal under R.5.a of this specification section.
J. After review by City or Engineer of each of Contractor’s submittals, two (2) sets of material will be returned to Contractor with actions defined as follows:
1. NO EXCEPTIONS TAKEN – A formal revision and resubmission of said submittal will not be required. Accepted subject to its compatibility with future submittals and additional partial submittals for portions of the work not covered in this submittal does not constitute approval or deletion of specified or required items not shown on the submittal.
2. MAKE CORRECTIONS NOTED (NO RESUBMISSIONS REQUIRED)
Same as 1 above, except that minor corrections as noted shall be made by Contractor.
3. AMEND AND RESUBMIT - Rejected because of major inconsistencies or errors that shall be resolved or corrected by Contractor prior to subsequent review by Engineer.
4. REJECTED - The submittal is illegible or the submittal is so far out of compliance with the contract documents that the Contractor needs to try again, from scratch.
K. Contractor shall make a complete and acceptable submittal at least by second submission. City reserves the right to deduct monies from payments due Contractor to cover additional costs of review beyond the second submission.
Illegible submittals will be rejected and returned to Contractor for resubmission.

Attachment: 2022 Traffic Calming Improvement Project Plans and Specifications (Approve Plans and Specs for the Annual Traffic Calming)
Technical Specifications 2022 Traffic Calming Improvement Project Page TP-14 Project No. C1807
responsibility for the accuracy, coordination and completeness of the submittals.
Accuracy, coordination, and completeness of Submittals shall be the sole responsibility of Contractor, including responsibility to back -check comments, corrections, and modifications from City or Engineer’s review before fabrication.
Contractor, subcontractors, or suppliers may prepare submittals, but Contractor shall ascertain that submittals meet requirements of Contract Documents, while conforming to structural space and access conditions at point of installation.
Engineer’s review will be only to determine if the items covered by the submittals will, after installation or incorporation in the Work, conform to the information given in the Contract Documents and be compatible with the design concept of the completed Project as indicated by the Contract Documents. Favorable review of submittal, method of work, or information regarding materials and equipment Contractor proposes to furnish shall not relieve Contractor of responsibility for errors therein and shall not be regarded as assumption of risks or liability by City or Engineer, or any officer or employee thereof, and Contractor shall have no claim under Contract on account of failure or partial failure or inefficiency or insufficiency of any plan or method of work or material and equipment so accepted.
Favorable review shall be considered to mean merely that City and/or Engineer has no objection to Contractor using, upon his own full responsibility, plan or method of work proposed, or furnishing materials and equipment proposed.
M. City and/or Engineer’s review will not extend the means, methods, techniques, sequences or procedures of construction or to safety precautions or programs incident thereto. The review and approval of a separate item as such will not indicate approval of the assembly in which the item functions.
N. Submit complete initial submittal for those items where required by individual specification Sections. Complete submittal shall contain sufficient data to demonstrate that items comply with Specifications, shall meet minimum requirements for submissions cited in technical specifications, shall include certifications, where required, and shall include necessary revisions required for equipment other than first named. If Contractor submits incomplete initial submittal, when complete submittal is required, submittal may be returned to Contractor without review.
O. It shall be Contractor’s responsibility to copy, conform and distribute reviewed submittals in sufficient numbers for Contractor’s files, subcontractors and vendors.
P. After City and/or Engineer’s review of submittal, revise as noted and resubmit as required.

R. All shop drawings and submittals shall be number identified by Contractor, prior to submission to Engineer, in accordance with the following:
1. Contractor shall sequentially number each submittal (i.e., “1”, “2”, “3”, etc.) as the basis for number identification of all shop drawings and submittals.
2. Affix the submittal number under which each submittal is made on every copy of each shop drawing, product data, sample, certification, O & M manual, etc.
3. If the submittal is a resubmittal (including without limitation after an initial submittal is rejected, returned not reviewed or marked revise as noted and resubmit), add the suffix designation “A” (i.e., a resubmittal of submittal 1 would be numbered 1A). Subsequent resubmittals would be identified by the submittal number and sequential letters (i.e., “B”, “C”, “D”, etc.).
4. All submittals shall include all information requested by each specification section. No partial submittals will be accepted unless previously authorized by Engineer. In the event a partial submittal is authorized, each subsequent different submittal (as opposed to resubmittal) is given a new number.
5. Number of resubmissions:
a. One reexamination of Contractor’s submittals that have been returned for correction or replacement will be included in Engineer’s scope. Any additional reexamination of Contractor’s submittals will be considered additional scope services to be paid by Contractor through City.

PG&E Gas and Electric Facilities Page 2
Attachment 1 – Gas Facilities
There could be gas transmission pipelines in this area which would be considered critical facilities for PG&E and a high priority subsurface installation under California law. Care must be taken to ensure safety and accessibility. So, please ensure that if PG&E approves work near gas transmission pipelines it is done in adherence with the below stipulations. Additionally, the following link provides additional information regarding legal requirements under California excavation laws: https://www.usanorth811.org/images/pdfs/CA-LAW-2018.pdf
1. Standby Inspection: A PG&E Gas Transmission Standby Inspector must be present during any demolition or construction activity that comes within 10 feet of the gas pipeline. This includes all grading, trenching, substructure depth verifications (potholes), asphalt or concrete demolition/removal, removal of trees, signs, light poles, etc. This inspection can be coordinated through the Underground Service Alert (USA) service at 811. A minimum notice of 48 hours is required. Ensure the USA markings and notifications are maintained throughout the duration of your work.
2. Access: At any time, PG&E may need to access, excavate, and perform work on the gas pipeline. Any construction equipment, materials, or spoils may need to be removed upon notice.
Any temporary construction fencing installed within PG&E’s easement would also need to be capable of being removed at any time upon notice. Any plans to cut temporary slopes exceeding a 1:4 grade within 10 feet of a gas transmission pipeline need to be approved by PG&E Pipeline Services in writing PRIOR to performing the work.
3. Wheel Loads: To prevent damage to the buried gas pipeline, there are weight limits that must be enforced whenever any equipment gets within 10 feet of traversing the pipe.
Ensure a list of the axle weights of all equipment being used is available for PG&E’s Standby Inspector. To confirm the depth of cover, the pipeline may need to be potholed by hand in a few areas.
Due to the complex variability of tracked equipment, vibratory compaction equipment, and cranes, PG&E must evaluate those items on a case-by-case basis prior to use over the gas pipeline (provide a list of any proposed equipment of this type noting model numbers and specific attachments).
No equipment may be set up over the gas pipeline while operating. Ensure crane outriggers are at least 10 feet from the centerline of the gas pipeline. Transport trucks must not be parked over the gas pipeline while being loaded or unloaded.
4. Grading: PG&E requires a minimum of 36 inc hes of cover over gas pipelines (or existing grade if less) and a maximum of 7 feet of cover at all locations. The graded surface cannot exceed a cross slope of 1:4.
5. Excavating: Any digging within 2 feet of a gas pipeline must be dug by hand. Note that while the minimum clearance is only 12 inches, any excavation work within 24 inches of the edge of a pipeline must be done with hand tools. So to avoid having to dig a trench entirely with hand tools, the edge of the trench must be over 24 inches away. (Doing the math for a 24 inch

Packet Pg. 357
Attachment: 2022 Traffic Calming Improvement Project Plans and Specifications (Approve Plans and Specs for the Annual Traffic Calming)
PG&E Gas and Electric Facilities Page 3
wide trench being dug along a 36 inch pipeline, the centerline of the trench would need to be at least 54 inches [24/2 + 24 + 36/2 = 54] away, or be entirely dug by hand.)
Water jetting to assist vacuum excavating must be limited to 1000 psig and directed at a 40° angle to the pipe. All pile driving must be kept a minimum of 3 feet away.
Any plans to expose and support a PG&E gas transmission pipeline across an open excavation need to be approved by PG&E Pipeline Services in writing PRIOR to performing the work.
6. Boring/Trenchless Installations: PG&E Pipeline Services must review and approve all plans to bore across or parallel to (within 10 feet) a gas transmission pipeline. There are stringent criteria to pothole the gas transmission facility at regular intervals for all parallel bore installations.
For bore paths that cross gas transmission pipelines perpendicularly, the pipeline must be potholed a minimum of 2 feet in the horizontal direction of the bore path and a minimum of 12 inches in the vertical direction from the bottom of the pipe with minimum clearances measured from the edge of the pipe in both directions. Standby personnel must watch the locator trace (and every ream pass) the path of the bore as it approaches the pipeline and visually monitor the pothole (with the exposed transmission pipe) as the bore traverses the pipeline to ensure adequate clearance with the pipeline. The pothole width must account for the inaccuracy of the locating equipment.
7. Substructures: All utility crossings of a gas pipeline should be made as close to perpendicular as feasible (90° +/- 15°). All utility lines crossing the gas pipeline must have a minimum of 12 inches of separation from the gas pipeline. Parallel utilities, pole bases, water line ‘kicker blocks’, storm drain inlets, water meters, valves, back pressure devices or other utility substructures are not allowed in the PG&E gas pipeline easement.
If previously retired PG&E facilities are in conflict with proposed substructures, PG&E must verify they are safe prior to removal. This includes verification testing of the contents of the facilities, as well as environmental testing of the coating and internal surfaces. Timelines for PG&E completion of this verification will vary depending on the type and location of facilities in conflict.
8. Structures: No structures are to be built within the PG&E gas pipeline easement. This includes buildings, retaining walls, fences, decks, patios, carports, septic tanks, storage sheds, tanks, loading ramps, or any structure that could limit PG&E’s ability to access its facilities.
9. Fencing: Permanent fencing is not allowed within PG&E easements except for perpendicular crossings which must include a 16 foot wide gate for vehicular access. Gates will be secured with PG&E corporation locks.
10. Landscaping: Landscaping must be designed to allow PG&E to access the pipeline for maintenance and not interfere with pipeline coatings or other cathodic protection systems. No trees, shrubs, brush, vines, and other vegetation may be planted within the easement area.
Only those plants, ground covers, grasses, flowers, and low-growing plants that grow unsupported to a maximum of four feet (4’) in height at maturity may be planted within the easement area.

Packet Pg. 358
Attachment: 2022 Traffic Calming Improvement Project Plans and Specifications (Approve Plans and Specs for the Annual Traffic Calming)
PG&E Gas and Electric Facilities Page 4
11. Cathodic Protection: PG&E pipelines are protected from corrosion with an “Impressed Current” cathodic protection system. Any proposed facilities, such as metal conduit, pipes, service lines, ground rods, anodes, wires, etc. that might affect the pipeline cathodic protection system must be reviewed and approved by PG&E Corrosion Engineering.
12. Pipeline Marker Signs: PG&E needs to maintain pipeline marker signs for gas transmission pipelines in order to ensure public awareness of the presence of the pipelines.
With prior written approval from PG&E Pipeline Services, an existing PG&E pipeline marker sign that is in direct conflict with proposed developments may be temporarily relocated to accommodate construction work. The pipeline marker must be moved back once construction is complete.
13. PG&E is also the provider of distribution facilities throughout many of the areas within the state of California. Therefore, any plans that impact PG&E’s facilities must be reviewed and approved by PG&E to ensure that no impact occurs which may endanger the safe operation of its facilities.

Attachment 2 – Electric Facilities
It is PG&E’s policy to permit certain uses on a case by case basis within its electric transmission fee strip(s) and/or easement(s) provided such uses and manner in which they are exercised, will not interfere with PG&E’s rights or endanger its facilities. Some examples/restrictions are as follows:
1. Buildings and Other Structures: No buildings or other structures including the foot print and eave of any buildings, swimming pools, wells or similar structures will be permitted within fee strip(s) and/or easement(s) areas. PG&E’s transmission easement shall be designated on subdivision/parcel maps as “RESTRICTED USE AREA – NO BUILDING.”
2. Grading: Cuts, trenches or excavations may not be made within 25 feet of our towers.
Developers must submit grading plans and site development plans (including geotechnical reports if applicable), signed and dated, for PG&E’s review. PG&E engineers must review grade changes in the vicinity of our towers. No fills will be allowed which would impair ground-to- conductor clearances. Towers shall not be left on mounds without adequate road access to base of tower or structure.
3. Fences: Walls, fences, and other structures must be installed at locations that do not affect the safe operation of PG&’s facilities. Heavy equipment access to our facilities must be maintained at all times. Metal fences are to be grounded to PG&E specifications. No wall, fence or other like structure is to be installed within 10 feet of tower footings and unrestricted access must be maintained from a tower structure to the nearest street. Walls, fences and other structures proposed along or within the fee strip(s) and/or easement(s) will require PG&E review; submit plans to PG&E Centralized Review Team for review and comment.
4. Landscaping: Vegetation may be allowed; subject to review of plans. On overhead electric transmission fee strip(s) and/or easement(s), trees and shrubs are limited to those varieties that do not exceed 15 feet in height at maturity. PG&E must have access to its facilities at all times, including access by heavy equipment. No planting is to occur within the footprint of the tower legs. Greenbelts are encouraged.
5. Reservoirs, Sumps, Drainage Basins, and Ponds: Prohibited within PG&E’s fee strip(s) and/or easement(s) for electric transmission lines.
6. Automobile Parking: Short term parking of movable passenger vehicles and light trucks (pickups, vans, etc.) is allowed. The lighting within these parking areas will need to be reviewed by PG&E; approval will be on a case by case basis. Heavy equipment access to PG&E facilities is to be maintained at all times. Parking is to clear PG&E structures by at least 10 feet.
Protection of PG&E facilities from vehicular traffic is to be provided at developer’s expense AND to PG&E specifications. Blocked-up vehicles are not allowed. Carports, canopies, or awnings are not allowed.
7. Storage of Flammable, Explosive or Corrosive Materials: There shall be no storage of fuel or combustibles and no fueling of vehicles within PG&E’s easement. No trash bins or incinerators are allowed.

8. Streets and Roads: Access to facilities must be maintained at all times. Street lights may be allowed in the fee strip(s) and/or easement(s) but in all cases must be reviewed by PG&E for proper clearance. Roads and utilities should cross the transmission easement as nearly at right angles as possible. Road intersections will not be allowed within the transmission easement.
9. Pipelines: Pipelines may be allowed provided crossings are held to a minimum and to be as nearly perpendicular as possible. Pipelines within 25 feet of PG&E structures require review by PG&E. Sprinklers systems may be allowed; subject to review. Leach fields and septic tanks are not allowed. Construction plans must be submitted to PG&E for review and approval prior to the commencement of any construction.
10. Signs: Signs are not allowed except in rare cases subject to individual review by PG&E.
11. Recreation Areas: Playgrounds, parks, tennis courts, basketball courts, barbecue and light trucks (pickups, vans, etc.) may be allowed; subject to review of plans. Heavy equipment access to PG&E facilities is to be maintained at all times. Parking is to clear PG&E structures by at least 10 feet. Protection of PG&E facilities from vehicular traffic is to be provided at developer’s expense AND to PG&E specifications.
12. Construction Activity: Since construction activity will take place near PG&E’s overhead electric lines, please be advised it is the contractor’s responsibility to be aware of, and observe the minimum clearances for both workers and equipment operating near high voltage electric lines set out in the High-Voltage Electrical Safety Orders of the California Division of Industrial Safety (
https://www.dir.ca.gov/Title8/sb5g2.html), as well as any other safety regulations.
Contractors shall comply with California Public Utilities Commission General Order 95 (http://www.cpuc.ca.gov/gos/GO95/go_95_startup_page.html) and all other safety rules. No construction may occur within 25 feet of PG&E’s towers. All excavation activities may only commence after 811 protocols has been followed.
Contractor shall ensure the protection of PG&E’s towers and poles from vehicular damage by (installing protective barriers) Plans for protection barriers must be approved by PG&E prior to construction.
13. PG&E is also the owner of distribution facilities throughout many of the areas within the state of California. Therefore, any plans that impact PG&E’s facilities must be reviewed and approved by PG&E to ensure that no impact occurs that may endanger the safe and reliable operation of its facilities.

CITY COUNCIL
STAFF REPORT
MEETING DATE: June 27, 2022
ITEM TITLE: Adopt a Resolution Approving the Plans and Specifications and Authorizing a Call for Bids for the 447 Hillcrest Wall Replacement Project C2203.
RECOMMENDATION:
Staff recommends that the City Council adopt a Resolution approving the plans and specifications and authorizing a call for bids for the 447 Hillcrest Wall Replacement Project C2203 (“Project”).
FISCAL IMPLICATIONS:
There are no fiscal implication s and no additional appropria tions are needed at this time.
Funding for the Project comes from C2203, which has a balance of $450,000 that was approved as part of the Fiscal Year 2022-23 budget.
Based on the engineer’s estimate, there is sufficient budget to award the base bid of t he Project with contingency. If the Project budget exceed s the available amount, staff will request the additional appropriation when the Project is presented to the City Council for award.
BACKGROUND:
The existing decorative wall along the property of 447 Hillcrest Road partially failed due to heavy rains in early 2020. Since then, maintenance staff has been securing the wall each winter to prevent complete failure and hillside slough off onto Hillcrest Road. However, the cost of securing the site every winter continues to escalate and a permanent solution is needed to secure the wall.
Staff retained Bellecci & Associates, Inc. (“Bellecci”) to provide recommendations and design for a permanent solution. Bellecci engaged a sub -consultant, Miller Pacific Engineering Group (“Miller Pacific”), to perform a site evaluation of the existing decorative wall and prepare a geotechnical engineering report with recommendations. Miller Pacific provided four options based on their site evaluation: a soldier pile and timber lagging retaining wall; a reinforced concrete retaining wall; a soil nail and shotcrete retaining wall; or , grade the slope and omit or shorten the wall. Miller Pacific recommended the soil nail and shotcrete retaining wall option because it is cost-effective and would maintain the existing wall height.
Staff concurred with the recommendation and requested that Bellecci move forward to prepare the final bid set construction documents for a soil nail and shotcrete retaining wall.

(C) For purposes of this section, mediation includes any nonbinding process, including, but not limited to, neutral evaluation or a dispute review board, in which an independent third party or board assists the parties in dispute resolution through negotiation or by issuance of an evaluation.

(D) Unless otherwise agreed to by the public entity and the contractor in writing, the mediation conducted pursuant to this section shall excuse any further obligation under Section 20104.4 to mediate after litigation has been commenced.
(E) This section does not preclude a public entity from requiring arbitration of disputes under private arbitration or the Public Works Contract Arbitration Program, if mediation under this section does not resolve the parties’ dispute.
(3) Failure by the public entity to respond to a claim from a contractor within the time periods described in this subdivision or to otherwise meet the time requirements of this section shall result in the claim being deemed rejected in its entirety. A claim that is denied by reason of the public entity’s failure to have responded to a claim, or its failure to otherwise meet the time requirements of this section, shall not constitute an adverse finding with regard to the merits of the claim or the responsibility or qualifications of the claimant.
(4) Amounts not paid in a timely manner as required by this section shall bear interest at 7 percent per annum.
(5) If a subcontractor or a lower tier subcontractor lacks legal standing to assert a claim against a public entity because privity of contract does not exist, the contractor may present to the public entity a claim on behalf of a subcontractor or lower tier subcontractor. A subcontractor may request in writing, either on his/her or her own behalf or on behalf of a lower tier subcontractor, that the contractor present a claim for work which was performed by the subcontractor or by a lower tier subcontractor on behalf of the subcontractor. The subcontractor requesting that the claim be presented to the public entity shall furnish reasonable documentation to support the claim. Within 45 days of receipt of this written request, the contractor shall notify the subcontractor in writing as to whether the contractor presented the claim to the public entity and, if the original contractor did not present the claim, provide the subcontractor with a statement of the reasons for not having done so.
A waiver of the rights granted by this section is void and contrary to public policy, provided, however, that (1) upon receipt of a claim, the parties may mutually agree to waive, in writing, mediation and proceed directly to the commencement of a civil action or binding arbitration, as applicable; and (2) a public entity may prescribe reasonable change order, claim, and dispute resolution procedures and requirements in addition to the provisions of this section, so long as the contractual provisions do not conflict with or otherwise impair the timeframes and procedures set forth in this section.
Nothing in this section shall impose liability upon a public entity that makes loans or grants available through a competitive application process, for the failure of an awardee to meet its contractual obligations.

Whether or not bids are opened exactly at the time fixed in the public notice inviting bids, any bid received after that time shall be returned unopened.
2.06 Approximate Estimate - The quantities listed in the bid schedule are approximate only, supplied as a general indication of the scope of work and to be used as a basis for comparing bids. The City does not expressly or by implication agree that the actual amount of work will correspond therewith, and reserves the right to increase or decrease the amount of any class or portion of the work, or to delete any portions of the work in their entirety, from the quantities listed on the bid schedule, as may be deemed necessary or advisable by the Engineer.

The bidder shall receive no additional compensation for obstacles or difficulties due to surface or subsurface conditions actually encountered. Where investigations of surface or subsurface conditions have been made by the City in respect to foundation or other structural design, and that information is shown in the plans, said information is included only for the convenience of bidders.

Such information shall be used as a basis for bids at the bidder's own and sole risk; making such information available to bidders is not to be construed in any way as a waiver of the other provisions of this paragraph, and bidders must satisfy themselves through their own investigation as to the surface and subsurface conditions to be encountered at the site. By submitting a Proposal, the Bidder has certified that he or she has examined all items indicated in Section 2 .07, "Examination of Plans, Specifications, and Site of the Work."

2.10 D isqualification of Bidders - More than one proposal from an individual, firm or partnership, a corporation, or an association under the same or different names will not be considered.

Proposals in which the prices obviously are unbalanced may be rejected.
2.11 Bid Protest Procedures – Any protest of the proposed contract award shall be submitted in writing to the City Clerk no later than 5:00 p.m. on the fifth (5 th) business day following the date of the bid opening.

(c) The party filing the protest must concurrently transmit a copy of the protest to the proposed awardee.
Any bidder’s failure to fully comply with these procedures shall constitute a waiver of any right to further pursue a bid protest, including filing of a challenge of the award pursuant to the California Public Contract Code, filing of a claim pursuant to the California Government Code, or filing of any other legal proceedings.
The City shall review all timely protests prior to the award of contract. The City shall not be required to hold an administrative hearing to consider any protests, but may do so at its option. The City Council or the City Manager as designee if the authority to award the contract has already been granted by the City Council, may either reject the protest and award the project to the lowest responsible bidder or accept the protest and award the project to the next lowest responsible bidder. Nothing in this section shall be construed as a waiver of the City Council’s right to reject all bids.
2.12 List of Subcontractors - In accordance with the provisions of Section 4104 of the Public Contract Code, each proposal shall list the name, address and license number of each subcontractor to whom the bidder proposes to sublet portions of the work.

SECTION 3: REVIEW OF BIDS, CONTRACT AWARD AND EXECUTION
3.01 Public Bid Opening and Initial Review - Bids which have been submitted in accordance with the requirements of the Bidding Documents, and which are received on or before the bid deadline will be opened publicly, and the dollar amounts of each bid shall be read aloud.
The City shall have the right to reject all bids. The City shall have the right to reject any bid not accompanied by the required bid security or any other item required by the Bidding Documents, or a bid which is in any other way incomplete or irregular. The City shall have the right to waive irregularities in a bid, and to award the Contract to the Lowest Responsible Bidder (as determined by the City), only if the irregularities are non-material and inconsequential.
3.02 Determination of Lowest Responsible Bidder - Criteria fo r determining low bid in all contracts with the City involving an expenditure of $5,000.00 or more shall be determined as the “Lowest Monetary Bidder” on the basis of the Engineer’s approximate estimate of the quantities of work to be done as set forth in the Bid Schedule, in accordance with the calculation criteria set forth on the bid.
After the Lowest Monetary Bidder has been determined, the Engineer shall review that Bidder’s bid in order to determine whether or not that Bidder is the “Lowest Responsible Bidder.” The term Lowest Responsible Bidder shall mean the Lowest Monetary Bidder whose bid is responsive, and who is responsible to perform the work, as required by the Contract Documents.
The term “responsive” is defined by California law, but generally means that the bid has been prepared and submitted in accordance with the Bidding Requirements. The term “responsible” is defined by California law, but generally means that the Bidder is able to demonstrate that it possesses: (1) the capacity to perform the work required by the Contract Documents with respect to financial strength, resources available, and experience; and (2) the integrity and trustworthiness to complete performance of the work in accordance with the Contract Documents.
The City will make its determination of responsibility based upon information submitted by Bidders contained in the Bidders Qualifications and Bidders References included in the Bid Forms and, if necessary, through interviews with previous cities, clients, design professionals, or subcontractors with whom the Bidder has worked. In determining whether or not a Bidder is responsible, the City may consider the following factors in relation to the work to be performed for this Project:
(a) D emonstrated financial strength including, but not limited to, resources available, bonding capacity, and available insurance.
(b) Demonstrated safety record including, but not limited to, Experience Modification Rate. (c) Successful completion of projects of similar scope and size. In reviewing this factor, the City may consider elements including, but not limited to, contract amount of completed projects, experience on public works projects, experience implementing prevailing wage certified payroll requirements, timeliness of performance and, if necessary, evaluation of the Bidder’s work by previous cities, clients, design professionals, or subcontractors. (d) Sufficiency of contract administration and construction management systems including, but not limited to, proposed scheduling tools, proposed subcontract forms, proposed progress payment applications, and proposed certification of payroll documents. (e) H istory of claims, litigation, termination or disqualification from projects.
If the Engineer finds that the Lowest Monetary Bidder submitted a responsive Bid and that the Bidder is responsible, then that Bidder shall be deemed the apparent “Lowest Responsible Bidder,” and the Engineer shall report the findings to the City Council.
If the Engineer finds that the Lowest Monetary Bidder’s bid is not responsive, or that the Lowest Monetary Bidder is not responsible, then the Engineer may review the responsiveness and responsibility
7.h.2
Packet Pg. 446
Attachment: 447 Hillcrest Wall Replacement Plans and Specifications (Approve Plans and Specs for the 447 Hillcrest Rd Wall Replacement GP-10
of the next Lowest Monetary Bidder. If the Engineer finds that the next Lowest Monetary Bidder is responsive and responsible, then that next lowest Bidder shall be deemed the apparent “Lowest Responsible Bidder,” and Engineer shall report its findings as recommendations to the City Council. This process may continue until the Engineer finds the Lowest Monetary Bidder which is also responsive and responsible.
In the event that one or more Low Monetary Bidders are found by the Engineer to be non- responsive or non-responsible, those Bidders will be given notice and a reasonable opportunity to present additional relevant evidence to the Engineer for consideration, within five (5) working days after the Bidder receives the notice.
All findings by the Engineer shall be reported as recommendations to the City Council. The City Council reserves the right to reject any or all Bids, and to waive any irregularity. No Bid shall be binding upon the City until after the Agreement is signed by both the Contractor and the City. If the City Council determines that it is in the City’s best interest to award the Agreement, a Notice of Award shall be sent to the Lowest Responsible Bidder as determined by the City Council. The City Council’s decision shall be final.
The City may investigate the responsibility and qualifications of all Bidders to whom the award is contemplated for a period not to exceed ninety (90) calendar days after the Bid opening, during which time no bid shall be withdrawn by the Bidders. The ninety (90) day review period may be extended upon the written request by the Engineer and written approval by the affected Bidder.
3.03 Notice of Award – Should the City decide to proceed with the award of contrac t the City shall issue a Notice of Award to the lowest responsible bidder.
3.04 C ontract Execution - Within fifteen (15) calendar days after receipt of the Notice of Award, the bidder shall submit to the City two (2) originals of the signed agreement, the required contract bonds and certificates of insurance. If the bidder fails or refuses to enter into a contract to do the work, then the proposal guaranty accompanying the bid shall be forfeited to the City. After the Bidder has properly submitted these documents, the City will execute the Agreement and issue a Notice to Proceed.
3.05 St
atus of Contractor - The right of general supervision by the City shall not make the contractor an agent of the City, and the liability of the contractor for all damages to persons or to public or private property arising from the contractor's execution of the work shall not be lessened because of such general supervision.
3.06 Assignment - No agreement or portion thereof maybe assigned without consent of the Council, except that the Contractor may assign money due which will accrue to him/her under the Agreement. If given written notice, such assignment will be recognized by the City to the extent permitted by law, but any assignment of money shall be subject to all proper setoffs and withholdings in favor of the City and to all deductions provided for in the Agreement.
