SUMMARY
On May 15, 2018, the City Council awarded a contract to Golden State Constructors

Antonio Road and the Gold Line Bridge. There was one (1) change order for extra work

The terms and conditions of this project have been complied with, and the work required
has been completed to the satisfaction of the Development Services Department for a
final cost of $198,358. It is recommended that the City Council accept the project as
complete and authorize the final payment in accordance with the approved contract
documents.
BACKGROUND
Over the years, local residents have advocated for the installation of sidewalk on
Colorado Boulevard between San Antonio Road and Santa Anita Avenue to connect the
neighborhoods bisected by the railroad crossing of Colorado Boulevard. As part of the
construction of the Gold Line, the City funded a betterment to lengthen the new bridge
over Colorado Boulevard to add a five-foot-wide sidewalk under the bridge on the north
and south side of Colorado Boulevard. In addition, on April 12, 2016, the Arcadia
Planning Commission approved MFADR 14-09 for the development of 20-unit
residential condominium project at 501 North Santa Anita Avenue. The developer was
conditioned to install a five-foot sidewalk on Colorado Boulevard east of the Gold Line
Bridge. This work was completed in 2017.

The Colorado sidewalk gap closure project was proposed to close the gap of missing
sidewalk between San Antonio Road and the Gold Line Bridge. In order to widen the
existing two-foot strip of concrete to a full five-foot wide sidewalk, a variable height
retaining wall was required to cut-back and support the existing slope. The new wall
was built to intersect the existing slope, and is not as high as the retaining wall adjacent
to the new development. The wall has a concrete finish to match the wall on the
adjacent property.
The project was advertised for bids in April 2018 and bids were opened May 1, 2018.
The low bid was from Golden State Constructors Inc. at $183,833. A contract in the
amount of $183,833 was awarded to Golden State Constructors Inc. on May 15, 2018 ,
along with a 10% contingency.
DISCUSSION
The construction began in July 2018 and was completed in October 2018. The
contractor initially encountered problems with the sandy soil under the concrete cap
over the slope. These issues included soil sloughing off underneath the cap, and a
portion of the unsupported concrete cap breaking off. However, the contractor and city
staff worked to resolve the problems, and the contractor did a good job of protecting the
existing slope and carefully completing the project, a small portion at a time, to minimize
problems.
There was one change order for extra work in the amount of $14,525 . The extra work
was to mitigate unforeseen conditions and make additional repairs as follows:
Remove the footing from the existing slope pavement wall that was in conflict
with the proposed sidewalk
Repair the damaged concrete slope
Repair an existing storm drain pipe that was unknown and damaged during the
slope removal
Repair previously damaged curb
The change order amount of $14,525 is 7.9% of the initial contract. The final contract
amount is $198,358.
FISCAL IMPACT
The project was budgeted in the Fiscal Year 2017-18 Capital Improvement Program,
with $150,000 from the Road Maintenance and Rehabilita tion fund (SB 1), and $50,000
from TDA Article 3 funds. The low bid was in the amount of $183,833. Since the
construction of the sidewalk for this project meets the eligibility requirements of the
City’s Miscellaneous Ramps and Sidewalk project, also budgeted in the Fiscal Year
2017-18 Capital Improvement Program, it is eligible for the use of TDA Article 3 funds.

No General Fund monies were used for this project and the budgeted amount is enough
to cover the final cost.
RECOMMENDATION

Constructors, Inc. for the Colorado Boulevard Sidewalk Gap Closure at Newcastle Park
as complete, and authorize the final payment be made in accordance with the contract
documents.
