CITY OF GROVER BEACH
CITY COUNCIL STAFF REPORT
Agenda Item No. 5
Placement: Consent
Meeting Date: September 22, 2025
TO: Honorable Mayor and City Council
FROM: Matthew Bronson, City Manager
PREPARED BY: Greg Ray, Public Works Director/City Engineer SUBJECT: Award of Construction Contract for: CIP Project 5002 – Sewer System Upgrades Project
RECOMMENDATION
Award a contract for construction of CIP Project 5002 Sewer Systems Upgrades Project to Souza Construction Company, Inc. in the amount of $3,405,329.00 for the Base Bid plus Additive Bid No.2; and authorize the City Manager to sign and affirm change orders up to an aggregate of $570,000; and authorize the Mayor to execute the contract on behalf of the City.
BACKGROUND
The City’s Sewer Master Plan was last updated in 2019 and identified deficiencies in the City’s existing sewer collection system. Some of the deficiencies identified require upgrades to meet the existing and future demands on the City’s sewer system. Staff prepared a multi-project plan to address the most critical deficiencies for existing and future flows which started with the upgrade of the segments in CIP 5002. Funding for this project was enabled through the Council’s adoption of a new sewer rate structure on June 9, 2025 and a subsequent bond financing agreement approved by the Council on September 8, 2025.
The project as bid includes upgrades to the following street segments:
• Manhattan Ave (from the west end to S. 4th Street)
• S. 4th Street (from Manhattan Ave to Longbranch Ave)
• N. 8th Street (from West Grand Ave to Ramona Ave)
• Ramona Ave (from North 8th Street to North 9th Street) • N. 9th Street (from Ramona Ave to Atlantic City Ave)
In addition, there were two bid additives included in the bidding package:
• Bid Additive 1: Highland Way (from Griffin St to 340 ft East) and Griffin St (from Highland to Calvin Court)
• Bid Additive 2: Rockaway Ave (from S. 4th Street to S. 9th Street) The project includes upsizing existing 8”, 10”, and 12” vitrified clay sewer mains to new 10”, 12”, and 18” HDPE sewer mains through a combination of pipe bursting and open-trench construction.
These upgrades provide the necessary capacity in the City’s sewer collection system to eliminate existing deficiencies and meet future demands.
Staff solicited bids for the project on August 7, 2025 with bids due on August 28. The estimated cost for construction for this project was $3.65 million which included both Bid Additive 1 and 2.
Attachment 2 shows the bid results with the low bid received from Souza Construction of $3.91 Staff Report: Award of Construction Contract for CIP 5002 Page 2 September 22, 2025
million including both Bid Additives. To provide sufficient funds for continued design of future sewer upgrades, staff recommends only the Base Bid and Bid Additive 2 be awarded at this time.
The estimated total project cost is $4.38 million which includes a contingency as well as construction management costs. Staff would note that the construction management contract was awarded separately and is not part of this agenda item. As a result, the project cost recommended for award includes the following items:
• Base Bid ($2.03 million)
• Bid Additive 2 ($1.38 million)
• 15% Contingency ($571,000)
FISCAL IMPACT
On September 8, 2025, the Council approved an Installment Purchase Contract and Conveyance Agreement for wastewater infrastructure bond financing for $5 million, including $4.8 million for the project and cost of issuance. Remaining bond funds available will be used for design of future sewer upgrades.
ALTERNATIVES
The Council has the following alternatives to consider:
1. Award a contract for construction of CIP 5002 to Souza Construction Company, Inc. in the amount of $3,405,329.00 for the Base Bid plus Additive 02; and authorize the City Manager to sign and affirm change orders up to an aggregate of $570,000; and authorize the Mayor to execute the contract on behalf of the City; or
2. Delay award of the project and provide additional direction to staff; or
3. Reject all bids and direct staff to modify the project and re-advertise for bids as soon as possible.
PUBLIC NOTIFICATION
The agenda was posted in accordance with the Brown Act.

BID FORM (cont.)
Bid Information
Bids are submitted for the entire Work. The amount of the bid for the entire Work will be the total of all of the subtotals for line items.
The subtotal of each line item will be determined by multiplying the unit price bid for the item by the estimated quantity for the item. The Bidder shall set forth for each line item of Work, in clearly legible figures, a unit price and a subtotal price for that item in the respective spaces provided for this purpose.
In case of discrepancy between the unit price for an item and the subtotal set forth for the item, the unit price shall prevail. However, if the amount set forth as a unit price is ambiguous, unintelligible or uncertain for any cause, or is omitted, then the subtotal amount set forth in the "Item Total" column for the item shall prevail in accordance with the following:
1. As to lump sum items (in other words, the estimated quantity is one), the subtotal amount set forth in the "Item Total" column shall be the item price.
2. As to unit price items (in other words, the estimated quantity is more than one), the subtotal amount set forth in the "Item Total" column shall be divided by the estimated quantity for the item, and the resulting price shall be the unit price.
The City reserves the right to reject any and all bids.
The BASIS OF AWARD of the Contract will be the lowest, responsive, and responsible ““BASE” Bid plus the additive bids.” (see below). The City, at its sole discretion, may or may not elect to award the contract, and may or may not elect to include any Alternate Bid Scopes in the contract. Bidders whose subcontractor performing pipe bursting are disqualified, will be determined nonresponsive and their bid will be rejected.
If this bid shall be accepted and the undersigned shall fail to enter into the Contract, to provide the certificate(s) of insurance and endorsement(s) as required by these Special Provisions, and to give the specified Payment Bond and Performance Bond with a surety that is satisfactory to the City, within ten (10) days, not including Saturdays, Sundays and legal holidays, after the Bidder has received notice from the City that the Contract has been awarded, the City may, at its option, determine that the Bidder has abandoned the Contract, and thereupon this bid and the acceptance thereof shall be null and void and the forfeiture of such security accompanying this bid shall operate and the same shall be the property of the City.
The undersigned, as Bidder, declares under penalty of perjury that the only persons or parties interested in this bid as principals are those named herein; that this bid is made without collusion with any other person, firm, or corporation; that he has carefully examined the location of the Work, the annexed proposed form of contract and the plans therein referred to; and he proposes, and agrees, if this bid is accepted, that he will contract with the City in the form of the copy of the Contract annexed hereto, to provide all necessary machinery, tools, apparatus and other means of construction, and to do all the Work and furnish all the materials specified in the Contract, in the manner and time therein prescribed, and according to the requirements of the Engineer as therein set forth, and that he will take in full payment the prices below.

Escrow Bid Documents will be used to assist in the negotiation of price adjustments, supplemental agreements, and contract modifications and in the settlement of disputes and claims. They will not be used for pre-award evaluation of the bidder’s anticipated methods of construction or to assess the bidder’s qualifications for performing theWork.
Bidders may submit Escrow Bid Documents in their usual cost- estimating format; a standard format is not required.

The Escrow Bid Documents shall be submitted in the English language.
It is required that the Escrow Bid Documents clearly itemize the estimated costs of performing the Work of each bid item contained in the bid schedule. Bid items should be separated into sub-items as required to present a detailed cost estimate and allow a detailed cost review. The Escrow Bid Documents shall include all quantity takeoffs, estimates of crews, and equipment, calculations of rates of production and progress, copies of quotes from subcontractors and suppliers, and memoranda, narratives, add/deduct sheets, and all other information used by the bidder to arrive at the prices contained in the bid.

Bid documents provided by the City should not be included in the Escrow Bid Documents unless needed to comply with the requirements herein.

The Escrow Bid Documents of the apparent successful bidder will be examined, organized, and inventoried by the Engineer, together with members of the bidder's staff who are knowledgeable in how the bid was prepared. This examination is to ensure that the Escrow Bid Documents are legible and complete. It will not include review of, and will not constitute acceptance of proposed construction methods, estimating assumptions, or interpretations of contract documents. Examination will not alter any condition or term of the contract.
If all the documentation required as indicated above has not been included in the original submittal, additional documentation may be required, at the City’s discretion, prior to award of the contract. The detailed breakdown of estimated costs shall be reconciled and revised, if appropriate, by agreement between the bidder and the City before making the award. Once it has been determined that all of the documentation has been included, the box will be sealed. The Contractor can choose to provide tamper proof tape, or security tape. Otherwise, the box will be sealed, and the tape will be signed. The Escrow Bid Documents will be placed in storage at City Hall.
If the contract is not awarded to the apparent successful bidder, the Escrow Bid Documents of the bidder next to be considered for award shall be processed as described.
Timely submission of complete Escrow Bid Documents is an essential element of the bidder's responsibility and a prerequisite to a contract award. Failure to provide the Escrow Bid Documents will be sufficient cause for the City to reject the bid.
Escrow Bid Documents submitted by unsuccessful bidders will be returned unopened, unless opened as provided above, following award of the contract. Unsuccessful bidders shall pick up the Escrow Bid Documents from the City 14 days of writtennotice.

Pass through clause.

Contractor agrees to monitor and review all such coverage and assumes all responsibility for ensuring that such coverage is provided in conformity with the requirements of this section. Contractor agrees that upon request, all agreements with consultants, subcontractors, and others engaged in the project will be submitted to City for review.
City’s right to revise requirements. The City reserves the right at any time during the term of the Contract to change the amounts and types of insurance required by giving the Contractor a ninety (90) day advance written notice of such change.

This test is done by plugging all the openings in the manholes and filling it with water to the same elevation as existed during the test. The leakage from the manhole may be deducted from the total leakage of the test section to calculate the test leakage of the pipe. After testing is complete, the manhole shall be waterproofed with grouting or other approved methods by the City.
E. If the leakage is greater than allowed, overhaul the pipe and, if necessary, replace and re-lay until the joints and pipe comply with this test. Complete tests before trench is paved.
3.05 AIR TEST
A. Conduct air tests per the following standards:
Pipe Material

Section
ASTM
Specification
PVC 333112 F1417, Table 1
HDPE 402097 F1417, Table 1
B. Test each section of pipe between two successive manholes by plugging pipe outlets with test plugs. Add air slowly until the internal pressure is raised to 4.0 psig. The compressor used to add air to the pipe shall have a blowoff valve set at 5 psig so that the internal pressure in the pipe never exceeds 5 psig. Maintain the internal pressure of 4 psig for at least two minutes to allow the air temperature to Docusign Envelope ID: 4CB44DCA-51A5-432F-ACCB-D2573091F878

stabilize, then disconnect the air supply and allow the pressure to decrease to 3.5 psig. Measure the time in minutes that is required for the internal air pressure to drop from 3.5 psig to 2.5 psig. Compare the results with the values tabulated in the referenced ASTM specifications above.
C. If the pressure drop from 3.5 psig to 2.5 psig occurs in less time than the specified values, overhaul the pipe and, if necessary, replace and re-lay the pipe until the joints and pipe hold satisfactorily under this test.
D. Guard against the sudden expulsion of a poorly installed plug or a plug that is partially deflated.
3.06 TEST FOR INFILTRATION
A. If, in the construction of a section of the sewer between structures, excessive groundwater is encountered, close the end of the pipe at the upper structure sufficiently to prevent the entrance of water. Discontinue pumping groundwater for at least three days. Then test the section for infiltration. The infiltration shall not exceed 0.025 gpm per inch of diameter per 1,000 feet of main line pipe being tested as measured at the downstream structure. Test period shall be at least eight hours.
B. Where infiltration exceeds the maximum acceptable, immediately uncover the pipe and reduce the infiltration to within the maximum acceptable by replacing, relaying, or encasing the pipe in concrete.
3.07 MANHOLE TEST
A. Watertightness of manholes may be tested in connection with hydrostatic tests of the pipeline or at the time the manhole is completed and backfilled. Repair any leakage as a result of testing.
B. Fill the manhole with water to an elevation 1 foot below the bottom of the cone section with a maximum water depth of 20 feet. Where the manholes are tested with the pipeline, no additional leakage will be allowed above that for the main line pipe.
C. Where a separate manhole leakage test is performed or requested by the Owner's Representative, plug inlets and outlets with stoppers or plugs and fill the manhole to the limits indicated above. The maximum allowable drop in the water surface shall be 1/2 inch for each 15-minute period of testing.
3.08 CORRECTION OF OBSERVED LEAKS
Even though the infiltration is less than the maximum acceptable, stop any individual leaks that may be observed.

402097-7
3.07 SIDEWALL FUSION
A. Accomplish side fusion procedure for HDPE in the field using 2- through 12-inch Faction Fusion (or equal) fusion units and heater saddle.
B. Clean and scrape the pipe (main).
C. Heat pipe and saddle via vacuum pressure.
D. Cleanly remove heating iron, bring melted surfaces together rapidly. Do not slam.
E. Set saddle on pipe and apply vacuum pressure of 21” to 29” of Hg or -10 to -14 psig
F. Joint cooling period at least 1.5 minutes per diameter inch of pipe.
G. Verify fusion seal with visual inspection and vacuum test with pressure of 21” to 30” Hg (-10 to -14.5 psig).
3.08 COMPATIBILITY FUSION
A. Manufacturer of pipe shall provide technical personnel to instruct and demonstrate the fusion procedure for joining dissimilar HDPE materials.
B. Compatibility heat fusion and sidewall fusion shall be accomplished in the same manner as described above with the following exception:
1. To achieve proper melt pattern, insert the heater plate and place a compatibility insulator between the heater plate and the lower melt material.
After the higher melt achieves proper melt, then remove the insulator and bring the heater plate in contact with the lower melt material for proper melt.
Continue heating both surfaces until proper melt develops. For manually operated fusion equipment, form a double roll-back bead as previously described in the fusion procedures.
3.09 STATIC ELECTRICITY DISCHARGING
A. Static electricity charges are generated on polyethylene pipe by friction, particularly during the handling of pipe in storage, shipping, and installation. The flow of air or gas containing dust or scale will also build up significant static charges, as will the flow of dry materials through the pipe. These charges are a safety hazard, particularly in areas where there is leaking gas or an explosive atmosphere.
B. Plastic pipe is a nonconductor of electricity and the static charge will remain in place until some grounding device comes close enough to allow it to discharge.

CIP 5002 SEWER SYSTEM UPGRADES PROJECT- AUG 2025
402097-8
C. The discharge of these static electric charges is the responsibility of the Contractor.
D. Do not drag HDPE pipe over the ground, drop it onto the ground, or drop objects on it.
