STAFF REPORT
Subiect:
Authorization for the Director of Development Services to execute Contract Change Order No. Three
to contract with David T. Wasden, Inc. for 9th Street Storm Drain Improvements from Waterman
Avenue to East Twin Creek Channel, per Plan No. 10676 and authorization for the Director of Finance
to amend the FY 2005/06 Budget.
Backe:round:
On November 3, 2003, the Mayor and Common Council awarded a contract in the amount of $273,040
to David T. Wasden, Inc. for 9th Street Storm Drain Improvements from Waterman Avenue to East
Twin Creek Channel.
Change Order No.1 was approved on October 4, 2004, in the amount of $10,894.66. This work
consisted of potholing along the alignment of the storm drain to determine locations of the existing
utilities. The change order also included removal of extra thick asphalt pavement which varied in
thickness varied from 7" to 12" thick, and additional traffic control that was necessary for crews
performing video inspection and cleaning of the sewer lines.
Change Order No.2 was approved on November 5, 2004, in the amount of $165,948. This large
change order primarily resulted from conflicts with Bubalo Construction, a contractor installing a large
water line in 9th Street for the San Bernardino Valley Municipal Water District. San Bernardino Valley
Municipal Water District acknowledged that its contractor's work had delayed the work of our
contractor and agreed to contribute $82,974 of the cost of Change Order No.2. San Bernardino Valley
Municipal Water District has been invoiced for the above amount.
Change Order No.3, in the total amount of$12,806.01, consists of the following changes:
1. During construction, an unidentified utility was discovered. The contractor was forced to remove,
disassemble, and then reassemble his trench shield to move past the utility. This process resulted
in delays to the project.
2. At the intersection of Bobbett Street and 9th Street, a conflict with a water main and valve cluster
was encountered. It was necessary to remove an existing concrete pad from beneath the valve
cluster to provide for clearance between the water valves and the new storm drain.
3. It was also discovered that there was inadequate clearance between the new storm drain and three
utilities. To ensure protection of the utilities, it was necessary to install concrete collars at the
crossings with the utilities.
4. The contractor elected to use a pavement grinder to remove the asphalt within the trench. Conflicts
with the operations of Bubalo Construction prevented David T. Wasden, Inc. from completing the
pavement removal in one operation. David T. Wasden, Inc. was required to move its equipment in
for a second time after Bubalo Construction completed work in the area. This resulted in a claim
by our contractor for additional compensation.

STAFF REPORT (Continued)
5. The project required an existing catch basin in 9th Street near Waterman Avenue to be connected
into the new storm drain. The existing catch basin was incorrectly constructed with a reverse slope
in the bottom. It was necessary for our contractor to modify the bottom of the existing catch basin
in order to achieve positive drainage from the catch basin into the new storm drain.
6. During construction, a sewer line was uncovered and determined to be leaking. It was necessary
for the contractor to repair the sewer prior to backfilling of the trench.
7. It was necessary to pour a concrete collar around an existing sewer main to provide adequate
support for the new storm drain.
8. The plans and specifications call for our contractor to base pave the trench to serve as a temporary
driving surface until the storm drain work was completed. After completion of all work, the plans
called for final asphalt pavement to be installed to produce a smooth, finished riding surface. Due
to scheduling conflicts between the storm drain project and the water main being installed by
Bubalo Construction, our contractor was unable to place the final cap and he indicated that he
would pull off the job until Bubalo Construction cleared the work area. David T. Wasden, Inc. also
indicated that additional mobilization charges would apply when he returned to place the final cap.
Rather than incur these additional charges, staff chose to eliminate the final asphalt concrete cap
from the project. The final asphalt concrete cap will be installed by City forces or by a separate
contract.
Staff is recommending that $40,000 to cover the cost of this change order and shortfall of
approximately $24,286 in the account be transferred from Account No. 248-368-5504-7316 "SD04-
08 State Street Storm Drain". The City is currently paying SAN BAG for its share of the cost of
State Street Storm Drain, which is currently under construction. Sufficient funds are available for
this transfer from the FY 2005/06 carryover in Account No. 248-368-5504-7316 and sufficient
funding will remain to meet all obligations for construction of the State Street Storm Drain.
The work involved in this project has been completed. Upon approval of this change order, the
project will be closed out.
Financial Impact:
The cost of this change order is $12,806.01. In addition to that cost, there is a shortfall of
approximately $24,286 in the account, which resulted from increased staff costs and inspection
requirements. Further, it is anticipated that approximately $3,000 in staff charges remain to be
made to the account. Therefore, staff is recommending that a total of $40,000 be transferred from
Account No. 248-368-5504-7316 "SD04-08 State Street Storm Drain" to Account No. 248-368-
5504-7429 "9th Street Storm Drain from Waterman Avenue to East Twin Creek (SD04-12)" III
order to cover the cost of this change order and the shortfall in the account.

Remove Debris Around Water Values
Existing water main and gate values had an excessive amount of concrete poured around
them. It was necessary to remove and dispose of the concrete debris to provide ample
s ace to install ro osed storm drain under the waterline and ate value.

It was necessary to pour and concrete collars around existing utilities to protect these
utilities to protect these utilities from damage, as there wasn't ample clearance from the
existing utilit to the ro osed storm drain.

It was necessary to have the trench ground in 2 stages to facilitate Bubalo Construction's
work. This re uired a second move-in of the avement rinder.

The existing catch basin, which was tied into the new storm drain, had reverse fall. It
was necessar to our a false bottom to correct the now.
