CITY OF HALLANDALE BEACH
MEMORANDUM
DATE: September 23, 2009
TO: D. Mike Good, City Manager
FROM: William M. Brant, P.E., Director, Utilities and Engineering
SUBJECT: Consideration to Increase Re-bid #
FY 2007-2008-006 – Golden Isles and SW 7th Bridge Improvements in the amount of
$113,168.54 to Anzac Contractors. – (BP 02/54)
PURPOSE:
Request the City Commission authorize an increase of the contractual sum for the Re-bid # FY 2007-2008-006 from $663,856.22 to $777,024.76.
BACKGROUND:
On December 3, 2008, the City Commission authorized the award of Re-bid # FY 2007-2008-006 to Anzac Contractors in the amount not to exceed $663,856.22. Construction of the bridges began early this year in February. The project is approximately 65 percent completed. The barrier walls for six of the locations are complete. The remaining work includes three additional barrier walls, lighting, painting and street resurfacing.
DISCUSSION:
An increase in the construction amount is requested due to safety issues identified by staff, the varying field conditions identified during construction and FPL requirements. The increase is in the amount of $113,168.54, which will bring the total contractual sum to $777,024.76, which is under the budgeted amount of $829,260. The project is scheduled to be completed by the end of November.
This increase is needed for the following reasons:
- The
old bridge on SW 7th Street did not have concrete approach
slabs before and after the bridge deck. These concrete segments allow
for a smoother transition from the roadway to the bridge and provide
reinforcement between the asphalt road section and the bridges. Due
to the increase in safety and increased long term stability, staff
recommended the installation of these additional segments of
concrete. The cost of this improvement included concrete and steel,
which totaled $15,033.20.
- Actual
construction quantities for the steel and concrete for the foundation and
barrier wall base have increased from the original bid quantities due to
the difference in elevations of the existing grades and the adjacent
bridges. Because this variance differed at each bridge, the concrete
and steel needed to be installed deeper in some locations more than
others. These exact elevations could not have been calculated until
the excavation occurred. The cost of the additional concrete and steel for
these changes is $77,540.74.
- Once
a project is ready for lighting service connection, FPL chooses the
location that they consider is most convenient for their services.
Some of the locations that were chosen are different from the locations
that were shown on the plans. In addition, the contractor needed an
additional plan detail for a riser diagram (a plan showing the wiring
needed to connect the light poles), that was not shown on the
drawings. The cost for the changes in location of the service
connection, and the additional plan detail totaled $20,594.60.
Even with the proposed increase, this amount is still lower than the next two lowest responsive bidders: M. Vila bid $1,000,397.80 and Weekley Asphalt bid $1,014,932.40. This change order has been reviewed by the City Engineer and the Director of Utilities and Engineering and they are in agreement with this proposed change order.
RECOMMENDATION:
Commission to authorize an increase of the contractual sum for the Re-bid # FY 2007-2008-006 from $663,856.22 to $777,024.76. If approved, funding is located in Account No. 440-3660-538.66-29.
Further, authorize the City Manager to establish accounts, make expenditures and execute all documents as required.
