Newport Boulevard Water Transmission Main Replacement — Approval of
Amendment No. 3 with Tetra Tech, Inc. C -5481 (CAP14 -0030)
The City entered into a Professional Services Agreement (PSA) and Amendment Nos. 1 and 2 with Tetra
Tech, Inc. for preliminary and final engineering services for the Newport Boulevard Water Transmission
Main Replacement project. Additional design services are needed to complete the construction
documents. Pursuant to Council Policy F -14, City Council approval is required in order to process this
Amendment No. 3.
RECOMMENDATION:
Approve Amendment No. 3 with Tetra Tech, Inc. for additional final engineering services for the Newport
Boulevard Water Transmission Main Replacement project at a not -to- exceed price of $50,500, and
authorize the Mayor and City Clerk to execute Amendment No. 3.
FUNDING REQUIREMENTS:
The current adopted CIP budget includes sufficient funding for the approval of Amendment No. 3.
The following fund will be expensed:
Account Description Account Number Amount
Water Enterprise Fund 7511- C6002014 $ 50,500.00
Total: $ 50,500.00
DISCUSSION:
The proposed water transmission main replacement project is located on the northbound side of Newport
Boulevard between Via Oporto and 19th Street. The existing pipeline consists of 16 -inch and 20 -inch cast
iron pipes that were installed in the mid 1920s. This transmission main is vital to the City's water
distribution system as it provides water supply and fire flow protection to businesses and residents on the
Balboa Peninsula. In addition to replacing the aging pipeline on Newport Boulevard, various smaller cast
10 -1
iron distribution mains on Finley Avenue, 32nd Street and various alleys will also be replaced.
The City is currently administering a separate street improvement project on Newport Boulevard within the
limits of this water transmission main project. Replacement of the water transmission main at this time
will eliminate the potential of damaging the old existing cast iron water main during construction of the
street improvements.
The final design is approximately 90 percent complete. As part of the plan review process, staff identified
the need to add several design features such as additional connections of distribution water mains and
corrosion protection measures. In addition, the replacement of several failed sewer mains within the limits
of this project has been added. Design services of these additional items were not included with the
original PSA or the two previously approved amendments. Staff recommends approving Amendment No.
3 at a not -to- exceed fee of $50,500 to complete these additional design services.
ENVIRONMENTAL REVIEW:
Staff recommends the City Council find this action is not subject to the California Environmental Quality
Act ( "CEQA ") pursuant to Sections 15060(c)(2) (the activity will not result in a direct or reasonably
foreseeable indirect physical change in the environment) and 15060(c)(3) (the activity is not a project as
defined in Section 15378) of the CEQA Guidelines, California Code of Regulations, Title 14, Chapter 3,
because it has no potential for resulting in physical change to the environment, directly or indirectly.
NOTICING:
This agenda item has also been publicly noticed according to the Brown Act (72 hours in advance of the
meeting at which the City Council considers the item).

Newport Beach, CA 92660
Reference: Newport Boulevard Water Main Replacement
Via Oporto to 28 "' Street and 26'^ Street to 19 " Street, Contract No. 5481
Amendment No. 3: Additional Work Request
Dear Mr. Tran:
Tetra Tech has been working with the City of Newport Beach on the Newport Boulevard Water Main
Replacement Project since July 2013. Our original proposal was for the preparation of the preliminary
design (approved budget of $36,600). Amendment No. I was for the preparation of final design and
construction support services for the portion of the water main replacement from Via Oporto to 28 "' Street
(approved additional budget of $152,400). Amendment No. 2 was for the preparation of final design and
construction support services for the portion of the water main replacement from 26 "' Street to 19"' Street
(approved additional budget of $47,000). In summary, our approved budget including Amendment Nos. I
and 2 is $236,000.
During the preparation of the final plans, Tetra Tech has been requested to perform additional items of
work that are above and beyond what we could have reasonably contemplated at the proposal time. By this
correspondence, Tetra Tech is requesting the City to increase our approved budget to compensate Tetra
Tech for these additional items of work.
ADDITIONAL ITEMS OF WORK
lien) No. l: Corrosion Control Plans
In both the proposal for Amendment Nos. I and 2, Corrosivity Evaluation as well as the corrosion control
plans were not included in the proposal (Phase 2, Item 1 in both proposals). Once steel pipe was selected by
the City for the portion of the replacement from Via Oporto to 281' Street, corrosion control site plan and
details were added to the construction drawings (Sheet D -1 I I and D -1 12). These plans were not included in
either Amendment No. I or Amendment No. 2.
Item No. 1: Additional Connection Details
Tetra Tech envisioned eight (8) connection details in Amendment No. I and another eight (8) connection
details in Amendment No. 2. At the 90 %n submittal, Tetra Tech has prepared a total of twenty -three (23)
connection details. In addition, due to utility congestion within Newport Boulevard, Tetra Tech was
required to prepare specific profiles for ten (10) of these connections. This was not anticipated in our
original proposals for Amendment Nos. I and 2. We are requesting additional monies for the preparation of
the additional seven (7) connections and for the preparation of the ten (10) connection lateral profiles.

Item No. 3: Sewer Reconstruction and Repair
During the design process, the City asked Tetra Tech to include the design of the sewer reconstruction and
sewer repair work included in the City's CIP that were located in the same streets as the water main
replacement work. This included the reconstruction of about loo feet of sewer in Finley (west) as well as
five (5) other locations of sewer repair work (within the alley adjacent to Finley, within the alley between
2911 and 291h, and within 2801 Street). This additional work included the plan callouts, preparation of a
profile for the reconstruction in Finley (west) and corresponding bid item descriptions within the
specifications.
Item No. 4: Sewer Replacement between 26'h Street and 22nd Street
Amendment No. 2 included the preparation of a plan and profile sheet for the sewer replacement work
between 261^ Street and 22 "d Street. Tetra Tech included this work in our 75% plan submittal. In the City's
75% plan check comments, the City deleted a portion of the sewer replacement work and revised the
alignment of the replacement to the OCSD manhole to be parallel in lieu of the Amendment No. 2 remove
and replace in the same alignment. Tetra Tech revised the plan and profile as requested by the City
comments. In the City's 90% plan check comments, the City has decided to return to the replacement in the
same alignment with the intent of building a new OCSD manhole. Tetra Tech feels these revisions are extra
work and is requesting a budget increase to compensate for these changes.
Item No. 5: Revise Plans from 16'h Street to 22 411 Street
Amendment No. 2 included the finalization of the plan and pmfile sheet between 261^ Street to 22"d Street
prepared for the developer by Tetra Tech. The plans were prepared based on replacement of the existing
services and fire hydrants to the developer's requested location of new meters/services. In the City's 75`70
plan check comments, Tetra Tech was directed to revise the plans to assume the developer has already
completed the construction of the new services and fire hydrants. Therefore, Tetra Tech had to revise the
plan and profile to delete the existing services and show the new services and fire hydrants as existing (at
the time of the proposed water main replacement construction).
Item No. 6: Changes to lire Design based on 90016 Plan Check Comments
The following is a summary of changes to the construction drawings based on the City's 90% plan check
comments. These comments were not included in the City's 75% plan check comments and due to the
timing will require additional effort by Tetra Tech to incorporate into the final design package.
• 20 -inch CIP connection at Via Oporto (replace the existing 20 -inch valve);
• Change the pipe size from 10 -inch to 12 -inch within the alley adjacent to Finley Ave.;
• Modify the fire hydrant connection within 32"d Street (extend piping in the street);
• Change the pipe size from 6 -inch to 8 -inch within 301^ Street;
• Add lateral to connect to existing dead -end hydrant on 291" Street;
• Revise profile within 281h1291h Street Alley;
• Revise sewer pipe from SDR -35 PVC to VCP (including specifications);
• Modify water service connections to existing meters (Detail 6 on D -106);
• Revised pipe material from DIP to PVC when less than 30- inches of cover:

• Evaluate need for additional air - vacuum assemblies based on comments; and
• Add alley replacement details for the 2P/29i1 Street alley.
It should be noted that Tetra Tech did add additional details between the 75% plan submittal and the 90%
plan submittal to include a cut -in -valve detail to minimize the loss of service during connections. This was
not initially anticipated in our original proposal.
