FROM: DOUGLAS S. STACK, DIRECTOR OF PUBLIC WORKS/CITY ENGINEER
SUBJECT: APPROVE PLANS AND SPECIFICATIONS AND AUTHORIZE A CONTRACT
CHANGE ORDER WITH R. J. NOBLE COMPANY AND PARSONS
TRANSPORTATION GROUP FOR SEWER WORK IN TUSTIN RANCH ROAD
AND BARRANCA PARKWAY AND FOR BARRANCA CHANNEL AND STREET
IMPROVEMENT WORK (CIP 70205)
SUMMARY
The plans and specifications for the new 20" permanent sewer in Tustin Ranch Road and Barranca
Parkway as well as the Barranca Channel and street improvement work are being prepared for
immediate construction subject to final approval by the City Engineer.
RECOMMENDATION
It is recommended that the City Council:
1. Adopt Resolution No. 13-52 approving the plans and specifications subject to final
engineering approval by the City Engineer;
2. Authorize a contract change order in the amount of $15,127,429 with the R.J. Noble
Company for construction and in the amount of $996,071 with the Parsons Transportation
Group for construction management for the sewer, channel, and roadway improvements
based upon bid pricing for similar work under contract and mobilized for the Tustin Ranch
Road Phase 2 Roadway Improvements; and
3. Appropriate $15,518,124 from unencumbered Tustin Legacy Backbone Infrastructure
Obligation Program proceeds in Fund 187 and remainder from Land Proceeds Fund 189
and appropriate $605,376 from Irvine Ranch Water District (IRWD) Reimbursement Fund
200 and authorize the City Manager to expend said funds in an amount not-to-exceed
$16,123,500 for construction installation, construction engineering, management and
inspection.
FISCAL IMPACT
The estimate for the construction installation, construction engineering, management and
inspection is $16,123,500 less $605,376 as a refundable obligation from IRWD for installation of
their capital domestic and reclaimed water facilities during this construction effort. Funding is
available from Tustin Legacy Backbone Infrastructure Obligation Program proceeds in Fund 187
and Land Proceeds Fund 189 in addition to the IRWD Reimbursement Fund 200.
DISCUSSION AND BACKGROUND
In March of this year during negotiations for the sale of Disposition Areas 2C & 8, it became
apparent that the installation of the permanent sewer within Tustin Ranch Road and Barranca
Sewer Work in TRR/Barranca and Barranca Channel and Barranca Parkway Project
June 18, 2013
Page 2
Parkway was necessary to remove the existing temporary sewer line within Disposition Area 2C to
complete the grading of these areas. Because of the depth and location of the future permanent
sewer running adjacent to the existing Barranca Channel, it is more cost efficient to construct the
Barranca Channel improvements at the same time as this permanent sewer. The requirement to
construct the Barranca Channel improvements as well as the Barranca Parkway widening
improvements were originally associated with the Disposition Area 2A transaction but were deleted
at the June 4 City Council meeting as a requirement in return for upfront payment of the Backbone
Infrastructure Obligation by The Irvine Company for that area which in turn can now be used to
fund the majority of these improvements. Attached is a plan and cross-section showing the
permanent sewer line in relationship to Tustin Ranch Road and the existing Barranca Channel.
R.J. Noble is currently completing the Tustin Ranch Road Phase 2 Roadway Improvements,
including sewer installations as well as storm drain box, laterals, and catch basin connections. The
estimates for this work are competitive with current contract prices. Two estimates for the
Barranca channel improvements were obtained from subcontractors currently working for R.J.
Noble and these were compared to the costs of the just-completed channel improvements by the
City of Irvine between Red Hill Avenue and just east of Aston Street. In addition, R.J. Noble's
estimate for the sewer work is $500,000 below the estimated cost for this work as provided by The
Irvine Company when they were approached to build this facility as part of the Disposition Area 2A
transaction requirements. It is estimated also that constructing the sewer with the Barranca
Channel improvements would save approximately $685,000 compared to constructing each facility
separately. The construction of the sewer can also best be accomplished prior to the opening of
the Tustin Ranch Road Extension at the end of this year to minimize disruption to the increased
traffic anticipated. Additionally, construction of the Barranca Channel improvements can best be
accomplished by starting now during the summer dry season months. Proceeding in this fashion
will also advance the entire construction operation by approximately 4.5 months and avoid
simultaneous disruptions along Barranca Parkway when Vestar begins their portion of the
Barranca Channel improvement project.
