CITY OF SAN BERNARDINO - REQUEST FOR COUNCIL ACTION
Staff Report
Subject.
Authorization to execute Contract Change Order No. Three with Holland-Lowe Construction,
Inc.—Street and Signal Improvements on 6' Street from "H" Street to Arrowhead Avenue and
authorization for the Director of Finance to amend the FY 2000/2001 budget and transfer
funds.
Background:
On April 3, 2000, the City entered into a contract with Holland-Lowe Construction, Inc. for
Street and Signal Improvements on 6' Street from "H" Street to Arrowhead Avenue per Plan
No. 9995. Change Order No. One in the amount of $2,461.00 was approved by the Director
of Development Services on May 8, 2000. This change order authorized the rewiring of the
existing signals at "D" Street and "G" Street, rework of a signal pole to clear an existing
storm drain lateral, and relocation of an illuminated street name sign to 5th Street and "E"
Street. Change Order No. Two in the amount of $7,430.00 was approved by the Mayor and
Common Council on July 10, 2000 and consisted of additional sidewalk on 6`h Street and repair
of a storm drain lateral.
Subsequently, certain conditions at the site were encountered which necessitated changes to the
design in order to provide a safe surface for traffic and to assure an adequate finished product.
Those changes are as follows:
Contract Change Order No. Three consists of the following items:
Description of Change Cost
1. Additional Cost to Add 3/8" Dense Fine Mix For Leveling
Course $82.34 tons. Cost is Based on Time and Materials $16,542.78
Costs.
** Reduction in rubberized Asphalt Concrete Pavement $ (4,293.33)
Net Change Order Amount I $11,619.45
Justification:
Upon completion of grinding of the existing pavement on 6`h Street between "H" Street and
"E" Street, it was discovered that the grinder had cut into a layer of "open graded" asphalt
which had been placed many years ago. This "open graded" asphalt raveled badly under
traffic, creating a significant amount of dust and an unsuitable driving surface even for the one
week period between grinding and the scheduled paving with rubberized asphalt pavement.
- 2 -
The contractor agreed to place a 3/8" thick leveling course of dense fine graded regular asphalt
concrete pavement to provide a suitable driving surface. The contractor agreed to perform this
work on a time and material basis, as provided under Section 3-3 "Extra Work" of the
Standard Specifications, so the price indicated is the actual cost of installing the leveling course
plus allowable mark-ups for overhead and profit.
** The cost of placing the leveling course is partially offset by a reduction in the quantity of
Rubberized Asphalt concrete Pavement placed by 63.65 tons, resulting in a reduction in cost to
the City of 63.63 tons x $77.35 per ton=$4,923.33.
A copy of Change Order No. Three is attached which will increase the contract total from
$270,412.35 to $282,031.80.
Financial Impact:
The total cost of change orders to date for this project, including Change Order No. Three, is
$21,510.45. The total amount of Change Orders Nos 1, 2, and 3 is within the $26,051.65
(10%) in contingencies approved as part of the award of the contract on April 3, 2000, from
Account No. 129-367-5504-7151 & 129-367-5504-7152 "Installation of Pedestrian Signals,
traffic signal loops and rehabilitation of 6"' Street."
However, during the budget review process, the account balance was reduced based on the
estimated cost of completing the project at the time. Subsequently, the need to place the base
course of paving was discovered which resulted in unanticipated costs. Therefore, Staff
recommends the transfer of $10,000 from Account No. 129-367-5504-7156 "Street
Improvements/Safety Improvements - Citywide" which has an FY00/01 balance of $200,000.
This transfer will reduce the FY 00/01 allocation for 129-367-5504-7156 "Street
Improvements/Safety Improvements - Citywide" to $190,000. The $10,000 transferred to 6`h
Street should be adequate to pay the cost of this Change Order and all other ancillary costs
necessary to complete the project, such as Staff time and laboratory testing costs.
Recommendation:
1. That the Mayor and Common Council authorize the Director of Finance to amend the
2000/2001 budget and transfer $10,000 from 129-367-5504-7156 "Street Improvements/Safety
Improvements - Citywide" to 129-367-5504-7152 "Installation of Pedestrian Signals, traffic
signal loops and rehabilitation of 6' Street".
2. That Contract Change Order No. Three to the contract with Holland-Lowe Construction, Inc.
be approved for Street and Signal Improvements on 6th Street from "H" Street to Arrowhead
Avenue for a net Change Order amount of $11,619.45, increasing the contract total from
$270,412.35 to $282,031.80.
