Authorization for the Director of Development Services to execute Contract Change Order No. One to contract
with David T. Wasden, Inc. for the "Replacement of Sewer Manholes at Various Locations in the City of San
Bernardino" (SW05-08) per project Plan No. 11341, and authorization for the Director of Finance to amend the
FY 05/06 Budget.
Backl!:round:
On September 7, 2004, the Mayor and Common Council allocated, as part of the FY 2004/5 Capital Improvement
Program (Crp), $80,000.00 in the sewer line construction fund for "Upgrade Clean-out Manholes" to City
Standard 48" Manholes. $78,300 was carried over and an additional amount of $50,000 was allocated in the FY
05/06 CIP for a total funding amount of approximately $128,300.
On August 15, 2005, a contract was executed with David T. Wasden, Inc. in the amount of $94,300 for
"Replacement of Sewer Manholes at Various Locations in the City of San Bernardino" (SW05-08) per project
Drawing No. 11341.
Contract Change Order No. One, in the amount of$120,272.77 consists of the following changes:
ITEM NO.
The removal of existing railroad tracks and ties at the intersection of 4tll St and
"D" St, 5th St and "D" St, & 6th St and "D" St needed to be executed prior to
1-1; 1-5; 1-6 any work being continued in the replacement of these manholes. The need to
remove these tracks was unforeseen; the tracks and ties are no longer the
responsibilitv of the railroad.
Additional excavation at 5th St and "D" St, 4th St and "D" St, & 4tn St and "F"
1-2; 1-7; 1-8 St was necessary due to existing conditions of the existing sewer clean-outs
being longer than anticipated, and not indicated on the Specifications originally
written for this proiect.
Installation of sewer casing was needed for support and for safety requirements
1-3 when crossing utilities. Some of the utilities were shown on the original
Specifications, and some were not noted. Hand excavation was necessary for
this Item.
Additional excavation with a chipping hammer was necessary due to the extra
1-4 thick concrete poured to support the existing c1eanouts. This needed to be
removed before continuation of the renlacement of this manhole.
Additional excavation for correction of the existing main line invert was
1-9 needed to continue beyond the original scope of work to straighten the main
line under the existing clean-outs and create a better flowing system.
Relocation of a 12" water line was necessary to continue with the project. The
1-9 Water Department has agreed to reimburse the City for any costs above $7,500
in relation to the relocation of a 12" waterline.
Removal of debris that was not reflected in the original Specifications was
1-10 . needed to continue this project. The excess debris was classified as brick and
concrete from a construction site.
Removal and installation of brick pavers was necessary due to the additional
excavation needed to remove the existing clean-outs. The clean-outs indicated
1-11 from research and field observations did not reflect the true conditions and
extra excavation that was needed to remove them. The above brick pavers that
were involved came out to 45.52 S.F.at a cost of $50.00 ner S.F.
