Public Works requests amendment to Del Mar Avenue sewer rehabilitation project

Back in February 2017, the City Council approved an agreement with Civiltec Engineering Inc. to provide engineering design services for the Del Mar Avenue sewer rehabilitation project with a purchase order of $245,836.30 that would replace the sewer main and reconstruct pavement along Del Mar Avenue between Chestnut Avenue and Dewey Avenue.

In April 2018, the City Council approved the amendment with Civiltec to include curb ramp designs with an increase of $266,226.30. This amendment is needed to help fund work with Southern California Edison for the SCE Transmission Overhead Line Undergrounding Project.

Funding is available in the City’s budget, with $12,609.50 paid by the developer of the 101 West Valley Boulevard Project, who requested the SCE Overhead Transmission Line Undergrounding Project.

Public Works staff recommends that the City Council approve the second amendment to the agreement with Civiltec and to approve an increase to purchase order by $25,519.00 for a total agreement amount of $291,745.30. Half of the additional amount ($12,609.50) will be reimbursed by the developer at 101 West Valley Boulevard.

Public Works requests additional engineering from RKA Consulting for San Gabriel Boulevard at Mission Road intersection improvement project

Back in 2006, the City entered into an agreement with RKA Consulting Group for on-call engineering services, including the design of the San Gabriel Boulevard at Mission Road intersection project. The initial design work totaled $203,400.00, with funding from the Gas Tax, Proposition C, Development Impact Fund, Measure R and Waste Management funds. The initial scope of work include a new traffic signal system, with the final design including intersection widening, additional lanes and new ADA-compliant curb ramps.

During construction, three contract amendments were approved by the City Council, increasing the total engineering cost to $496,780.00. Additional costs for the project were incurred as a result of right-of-way acquisition costs and design changes to coordinate with the San Gabriel Boulevard Streetscape Master Plan. Additional engineering services were also required because the project schedule was extended six months to accommodate utility conflicts and unforeseen underground structures.

Public Works staff is recommending that the City Council approve an amendment with RKA Consulting Group for additional engineering services for the San Gabriel Boulevard at Mission Road intersection project in the amount of $29,541.50 for a total agreement cost of $526,321.50 and to authorize a purchase order change in the amount of $29,541.50.

Finally, the City Council will be reviewing the following items:
