iii
MODIFICATIONS AND ALTERNATIVE PROPOSALS
Unauthorized conditions, limitations, or provisions attached to the Proposal will render it informal and may be grounds for its rejection as non-responsive. The completed Proposal forms shall be without interlineations, alterations, or erasures. Alternative proposals will not be considered unless specifically requested. Oral, telegraphic, or telephonic proposals or modifications will not be considered.
DISCREPANCIES IN PROPOSALS
In the event there is more than one bid item in a Bidding Schedule, the bidder shall furnish a price for all bid items in the Schedule, and failure to do so will render the Proposal informal and may be grounds for its rejection as non-responsive. The bidder shall state in words and figures the unit prices or the specific sums as the case may be, for which it proposes to supply the labor, materials, supplies, or machinery, and completely perform the Contract. The total amount of each item bid and the total amount of the bid shall be stated in words and figures.
In case of any discrepancy between the words and the figures, the words shall prevail. If the unit price and the total amount named by a bidder for any items are not in agreement, the unit price alone will be considered as representing the bidder's intention and the total will be corrected to conform thereto.
PROPOSAL GUARANTEE – BIDDER’S SECURITY
Each bidder shall submit with his Proposal cash, an unconditional certified or cashier's check, or a bidder's bond, in the sum of the percentage of the bid stated in the Notice Inviting Bids, payable to the City as a guarantee that the bidder will, if its Proposal is accepted, execute the Contract and furnish a satisfactory Faithful Performance Bond, a satisfactory Payment Bond and insurance certificates as specified herein.
If a bidder to whom an award is made, fails or refuses to sign the Contract or furnish the required bonds and certificates, all within the time stated in Section 2-1.5 of the Special Provisions herein, the funds represented by said cash, check or bidder's bond shall be forfeited and become and remain the property of the City; the amount thereof being agreed to by the bidder and the surety as a bid bond forfeiture due the City because of the delay in the execution of the Contract and in the performance of work thereunder, resulting from such failure or refusal, except that if the City awards the contract to the next lowest responsive responsible bidder, only that portion of the bidder's security equal to the difference between the two bids will be forfeited.
A Bid Bond must be obtained from a corporate surety authorized to do business as such in the State of California as an “admitted surety insurer” and shall be on the form furnished by the City or one substantially in conformance with it. Certified or cashier's checks must be drawn on a solvent state or nationally chartered bank or branch thereof in the State of California. The liability of the City in connection with the checks shall be limited to the return of the checks (without interest) as provided in Section 2-1.6 of the Special Provisions bound herein.
DISQUALIFICATION OF BIDDERS
A person, firm, or corporation shall NOT be allowed to make or file, or to be interested in, more than one bid, except an alternative bid when specifically requested; provided, however, a person, firm, or corporation who has submitted a sub-proposal to a bidder submitting a iv
Proposal, or who has quoted prices on materials to such bidders, is not thereby disqualified from submitting a sub-proposal or from quoting prices to other bidders submitting proposals, or from submitting a Proposal as a prime contractor. Similarly, failure to comply with the registration requirements of Labor Code Section 1725.5, as further described in the Notice Inviting Bids, will disqualify a bidder.
ADDITIONAL REQUIREMENTS
The bidder's attention is directed to the Special Provisions and Technical Provisions bound herein for additional requirements of the Proposal and Contract Documents.

Unless extended by agreement of the City, failure to timely submit executed Contract Documents may be grounds for rejecting the bid award and forfeiture of the bid security.

3. The undersigned contractor is aware of California Public Contract Code Section 6109, which states:
“(a) A public entity, as defined in Section 1100 [of the Public Contract Code], may not permit a contractor or subcontractor who is ineligible to bid or work on, or be awarded, a public works project pursuant to Section 1777.1 or 1777.7 of the Labor Code to bid on, be awarded, or perform work as a subcontractor on, a public works project.

INSTRUCTIONS FOR CERTIFICATION
1. By signing and submitting this proposal, the prospective primary participant is providing the certification set out below.
2. The inability of a person to provide the certification required below will not necessarily result in denial of participation in this covered transaction. The prospective participant shall submit an explanation of why it cannot provide the certification set out below. The certification or explanation will be considered in connection with the department or agency's determination whether to enter into this transaction. However, failure of the prospective primary participant to furnish a certification or an explanation shall disqualify such person from participation in this transaction.
3. The certification in this clause is a material representation of fact upon which reliance was placed when the department or agency determined to enter into this transaction. If it is later determined that the prospective primary participant knowingly rendered an erroneous certification, in addition to other remedies available to the Federal Government, the department or agency may terminate this transaction for cause or default.
4. The prospective primary participant shall provide immediate written notice to the department or agency to which this proposal is submitted if at any time the prospective primary participant learns that its certification was erroneous when submitted or has become erroneous by reason of changed circumstances.
5. The terms "covered transaction," "debarred," "suspended," "ineligible," "lower tier covered transaction," "participant," "person," "primary covered transaction," "principal," "proposal," and "voluntarily excluded," as used in this clause, have the meanings set out in the Definitions and Coverage sections of the rules implementing Executive Order 12549.

8. A participant in a covered transaction may rely upon a certification of a prospective participant in a lower tier covered transaction that it is not debarred, suspended, ineligible, or voluntarily excluded from the covered transaction, unless it knows that the certification is erroneous. A participant may decide the method and frequency by which it determines the ineligibility of its principals. Each participant may, but is not required to, check the Nonprocurement List.
9. Nothing contained in the foregoing shall be construed to require establishment of a system of records in order to render in good faith the certification required by this clause. The knowledge and information of a participant is not required to exceed that which is normally possessed by a prudent person in the ordinary course of business dealings.
10. Except for transactions authorized under paragraph 6 of these instructions, if a participant in a covered transaction knowingly enters into a lower tier covered transaction with a person who is suspended, debarred, ineligible, or voluntarily excluded from participation in this transaction, in addition to other remedies available to the Federal Government, the department or agency may terminate this transaction for cause or default.

GP-3
1-7.2 Contract Bonds. The “Performance Bond” is equivalent to City’s “Faithful Performance Bond”.
1-7.3 Examination of Plans, Specifications and Project Site. Bidders shall read the specifications, review the drawings and examine the existing facilities to fully understand the project in order to plan for the improvements as shown in the contract, including local condition, uncertainty of weather and all other contingencies.
Bidders shall satisfy themselves by personal examination of the proposed work sites, and by such other means as they may choose as to actual conditions and requirements and as to the accuracy of the quantities stated in the Proposal forms. Information derived from the maps, plans, specifications, profiles, drawings, or from the Engineer/Architect of the record, shall not relieve the bidder of this responsibility, and the interpretation of the data disclosed by borings or other preliminary investigations is not guaranteed nor is any liability assumed by the Agency. 1-7.4 Interpretation of Drawings and Documents.

After the Proposals have been publicly opened and read aloud, they will be checked for accuracy and compliance with all provisions as specified herein.
The Agency reserves the right to reject any or all bids and to waive any informality or irregularity in any bid received and to be the sole judge of the merits of the respective bids received.
Bids subsequently shown to be mathematically unbalanced would be rejected as nonresponsive.
A mathematically unbalanced bid is one containing lump sum or unit bid items which do not reflect reasonable actual costs plus a reasonable proportionate share of the bidder’s anticipated profit, overhead costs, and other indirect costs, which he/she anticipates for the performance of the items in question.
“A bid is mathematically unbalanced if the bid is structured on the basis of nominal prices for some work and inflated prices for other work; that is, each element of the bid must carry its proportionate share of the total cost of the work plus profits.” “A bid is materially unbalanced if there is a reasonable doubt that award to the bidder submitting the mathematically unbalanced bid will result in the lowest ultimate cost to the Government.
Consequently, a materially unbalanced bid may not be accepted.” Award of the Contract, if it be awarded, will ordinarily be made by the Agency within 30 days after opening of the bids. Award will be made to the lowest responsive responsible bidder.
In selecting the lowest responsive responsible bidder, consideration will be given to the general competency of the bidder for the performance of the work covered by the proposal. To receive favorable consideration, a bidder may be required to present evidence that he has successfully performed similar work of comparable magnitude or submit other evidence satisfactory to the GP-4
Agency that he or his associates are competent to manage the proposed undertaking and to carry it forward to a successful conclusion. Professional integrity and honesty of purpose shall be essential requirements. A showing of adequate financial resources may be required but will not alone determine whether a bidder is competent to undertake the proposed work.
Only manufacturers or contractors of established reputation, or their duly authorized dealers or agency, having proper facilities for the manufacture of the materials or equipment and for servicing same, or for proper execution of the work called for in the contract, will be considered in making the award.
1-7.6 Execution of Contract. A bidder whose proposal is accepted shall properly sign a written contract with the Agency on the form attached hereto and return said contract together with good and approved bonds and insurance certificates as required by the Contract Documents within twenty-one (21) calendar days from the date of the mailing of a notice from the Agency to the bidder, according to the address given by him, of acceptance of his proposal.
Contract bonds and certificates of insurance, if required, shall be filed in all instances before delivering any equipment, materials, or performing any work under the contract; also before any purchase order shall be issued. An executed Power of Attorney form shall be submitted with all contract bonds herein specified.
If a bidder whose proposal is accepted fails or refuses to enter into a contract as herein provided, or to conform to any stipulated requirement in connection therewith, the money represented by his check or bidder’s bond shall be refunded less the difference between the low bid and the bid of the bidder with whom the Agency enters into an agreement in accordance with the provisions of the Public Contracts Code Section 20174. At the discretion of the Agency, an award may be made to the bidder whose proposal is next most acceptable to the Agency, and such bidder and his surety shall fulfill every stipulation embraced herein as if he were the party to whom the first award was made.
A corporation to which an award is made may be required before the contract is finally signed to furnish evidence of its corporate existence, of its right to do business in California and of the authority of the officer signing the contract and bonds for the corporation to so sign. 1-7.7 Return of Proposal and Guarantee. The check or bond of a bidder to whom the contract has been awarded will be returned to him after all of the acts, for the performance of which said security is required, have been fully performed. The checks or bid bonds of the second and third lowest bidders will be returned when the bidder to whom the contract has been awarded has properly executed all of the required Contract Documents. Check or bid bonds of other bidders will be returned when their proposals are rejected or in any event at the expiration of forty-five (45) days from the date of opening bids.

d. Natural Hedge - The intent is to develop a loose, informal appearing hedge which requires only minimal attention to keep in shape and size. Initially, pinch prune to keep compact. Allow to fill solid horizontally. This is critical to avoid legginess.
e. Formal Hedge - It is the intent for these shrubs to have straight crisp edges. Initial pinch pruning with shears will encourage the shrubs to fill in. f. Prune at the correct time of year to maximize flowering potential. g. After flowering, remove any spent blossoms on flower stalks.
2. Fertilization:
a. Fertilize 4 times per year apply Tri-C Premium Humate 8 LBS.per 1000 sq. ft.
b. Due to area soil conditions, supplemental feedings of iron may be required to prevent chlorosis.
c. Contractor shall be responsible to apply all materials required to correct mineral deficiencies affecting plant growth.
3. Weed, Pest and Disease Control:
a. Contractor shall maintain weed, pest and disease-free shrub/beds at all times.
b. All Shrub area not underplanted with groundcover will be raked clean and cultivated minimum of every other week.
c. Apply pesticides as required to control and prevent disease/insects.
C. Trees:
1. No tree work shall be done without prior approval and direction from City's representative.
2. Trees shall be pruned as required to remove broken, diseased branches or for genera containment. It shall be Contractor’s prime responsibility related to pruning to conduct a pruning program which must be approved by the City's representative. This program should develop proper tree scaffolding, strength, and appearance consistent with intended use.
3. Tree stakes, ties and guys shall be checked and corrected as needed. Ties will be adjusted to prevent girdling. Remove unneeded stakes, ties and guys.
4. Pruning is limited to that which may be done from the ground (up to fifteen (15) feet).
5. Apply all chemical controls, such as insecticides, as required to control or prevent pests.
6. Fertilize all trees as needed. Trees may require deep root feeding foliar application.
7. Prune trees to allow for the necessary clearances for pedestrians and vehicle circulation, with a minimum canopy clearance of eight (8) feet - twelve (12) feet maximum.
8. Surface roots which become maintenance or appearance problems will be removed as required to prevent damage to adjacent paved areas. This shall be considered extra work.
IRRIGATION SYSTEM
A. Controller
1. Contractor is to adjust his watering schedule equal to the percolation rate each area is capable of receiving based on topography, soil type, plant material, season or climate factors.
2. Contractor shall utilize repeat cycle on controller to eliminate excessive runoff.
3. Hours of scheduled operation will be programmed based upon Solar Sync Logic component and reviewed by Contractor on a monthly basis to minimize disease occurrence of plant material and to reduce possible nuisance from sprinkler operation to pedestrians or vehicles.
4. Locks and keys will be provided by the City's representative.
5. Contractor shall perform preventative maintenance as needed.
B. Operation of System
1. All systems shall be personally observed during operation cycle at least once per month to verify effectiveness of sprinkler operation.
2. Contractor will adjust and clean, as necessary, all sprinkler heads, valves, and pressure reducers to continue operation at maximum efficiency and performance.
3. Sprinkler heads in planter areas shall be kept clear of overgrowth which may obstruct maximum operation.
4. Contractor will be responsible for trimming and making necessary adjustments to riser height as growth rates indicate to prevent "elephant tracks".
5. Contractor shall be responsible for keeping interior of valve boxes clean. A clean gravel base shall be maintained at all times.
6. Dripline systems shall be flushed on a semi-yearly basis C. Repairs
1. Any repairs made by the Contractor will be in accordance with current practices or as directed by City's representative.
a. Current Practices:
(1) Use similar dripline tubing and / or repair and flush lines if damaged during operations.
2. Repairs to irrigation system caused by conditions under which Contractor does not have direct control shall be paid for by the City as extra work. Repairs under this shall be vandalism, normal wear and tear, storm damage (Acts of God).
3. Malfunctions of any nature which are deemed to be the fault of materials or workmanship still covered under original installation guarantee shall be reported immediately to the City's representative.
4. Contractor will maintain an accurate up-to-date record of all irrigation repairs, stating date of repair, specific location, and nature of repair. This log must accompany a monthly itemized invoice.
5. Landscape areas will be returned to original condition following any irrigation repairs or replacements.
CLEAN-UP
Contractor will remove all debris resulting from the maintenance operations at the project and dispose of according to City policies.
