CITY OF SAN BERNARDINO - REQUEST FOR COUNCIL ACTION
8T AFF REPORT
Subiect:
Authorization for the Director of Development Services to Execute Change Order No. One to
Contract with Hillcrest Contracting, Inc. for Street Improvements and Beautification Project on
Victoria Avenue from 28th Street to Lynwood Drive (Phase I) (8S05-25), per Project Plan No.
11619.
Backl!round:
On August 7, 2005, the Mayor and Common Council allocated funds, as part of the FY 2006/07
Capital Improvement Program (CIP), for street and beautification improvements on Victoria
A venue from 28th Street to Lynwood Drive as Project No. SS05-25.
The San Manuel Tribe has contributed $5,500,000 to the City of San Bernardino to address
traffic impacts from its new casino on Victoria Avenue between Highland Avenue and Lynwood
Drive.
On October 2, 2006, Mayor and Common Council awarded a contract to Hillcrest Contracting,
Inc. for Street Improvements and Beautification Project on Victoria A venue from 28th Street to
Lynwood Drive (Phase I) (SS05-25), per Project Plan No. 11619.
At the pre-construction meeting, it was determined that the proposed sound wall design using a
70 mph wind load would be insufficient in the area of construction. City staff directed the
contractor to redesign the wall using an 80 mph wind load. The design difference made the
footings closer together, which increased the footing size. During design, it was decided to grind
the lip of the existing curb ramps to meet ADA requirements. If this was done, the ramps would
not meet the minimum slope. The City required the contractor to remove the ramps and install
new ramps that conform to the latest ADA regulations.
When installing the proposed sound wall, it was found that the footings for the existing walls
were extended out 2 feet, which caused the new sound wall to be located 2 feet closer to the
curb. The meandering sidewalk, which had 2 feet of landscaping between it and the edge of the
sidewalk had to be eliminated, also causing the irrigation lines to be sleeved. An unmapped 42-
inch diameter storm drain line was discovered while excavating for the sound wall footings and
was in conflict with the new sound wall and had to be relocated. Potholing of existing utilities
was necessary to design the relocation of the storm drain. While potholing, it was discovered
that hazardous material was under the existing street. The City requested that the material be
removed. Our contractor provided traffic control and excavation for Brickley Environmental,
who was certified to remove hazardous material, then closed, compacted and paved the above-
mentioned site. Power for the new traffic signal had to be relocated, due to SCE location of an
existing source of power approximately 530 feet further than anticipated. In order for the signal
to operate, the City chose to have the contractor install the needed conduit.
Change Order No. One, in the amount of $480,240 consists of the following changes:
Item No. 1-1
Item No. 1-2
Decrease post spacing from 24 feet on center to 8 feet on center.
Construction of additional sidewalk, curb and gutters and convert spandrel.

Originally, the project budget was $5,500,000. After deducting engineering and construction
costs of the Phase I, the remaining budget was $2,684,400. After this change order, the
remaining budget will be $2,204,160. This amount, plus the interest accrued from the original
deposit in October, 2004 (estimated at $600,000), should be sufficient to complete Phase 2 of the
project.

Justification
1-1
, Decrease Post Spacinl! from 24 ft. on Center to 8 ft. on Center
The original design for the sound wall was based on a 70-mph wind load. The wind load
criteria on Victoria Ave. is 80 mph. Using the 80 mph wind load, the spacing of the
. vertical post was decreased from 24 ft. on center to 8 ft. on center; therefore, requiring
I additional posts and footings. I

Change Order No. One
Hillcrest Contracting, Inc. - Street Improvement & Beautification Project on Victoria Avenue, Phase!, 28th Street to
Lynwood Drive (SS05-25), per Project Plan No 11619.
Construct Additional Sidewalks. Curb and Gutter & Concrete Soandrels
During construction, it was detennined that there were numerous existing wheelchair
ramps, which did not confonn to A.D.A. standards. The approved plans and
1-2 specifications required these ramps to be field ground for repairs. The field grinding
would not bring the ramps into A.D.A. compliance; therefore, the contractor was directed
to remove and replace the ramps. Additional 1,023 feet of sidewalk was removed to
accommodate the construction of the sound wall. This additional 1,023 feet of sidewalk
was not shown for removal and replacement on the aooroved olans.
Install Additional Irril!ation Sleeves
Originally, the new sidewalk was designed to meander between the back-of-curb and face
1-3 of new sound wall. It was necessary to modifY the sidewalk design, as the area between
the curb and wall was not as wide as shown on the plans. This modification required
additional sleevinl! under the sidewalk for the proposed irril!ation lines.
Additional Survevinl!
1-4 The new design of the sound walls required the post to be on 8-feet center rather than 12
ft. on center. This reauired additional surveying to detennine too of wall elevations.
Install3-incb Conduit
A new traffic signal is to be constructed at Lynwood St. and Victoria Ave. The approved
1-5 plans did not indicate electrical feed from S.C.E. The contractor was directed to install
530 ft. of 3-inch conduit to provide electrical power from the S.C.E. hand hole to the
Meyers cabinet.
Aided in tbe Hazardous Material Removal
1-6 Hillcrest Contracting, Inc. was potholing for utility location and discovered a buried
hazardous waste (asbestos). The contractor was directed to aid in the removal of the
hazardous waste.
Potbole Utilities for Prooosed Storm Drain
During construction, it was discovered that the existing stonn drain was located next to
1-7 existing block wall. This is the same location as the new footing for the new sound wall.
The contractor was directed to pothole the existing utilities to provide vertical and
horizontal control for the desiJm of a new stonn drain.
Construct New 42-incb Storm Drain
1-8 The existing stonn drain was located in the parkway on the west side of the street. The
location is the same alignment as the proposed sound wall. A new stonn drain was
designed and to be installed in the northbound lane of Victoria Ave.
