CITY COMMISSION
STAFF REPORT
AGENDA ITEM: Authorization for Staffto Develop Design/Build Specifications for
Dutton Road Culvert
DATE: March 17, 1999
SUBMITTED BY: David E. Thompson, City Manager
BACKGROUND: One of the first steps in the development of Pine Island Park
(Dutton Island) is to assure that vehicular traffic can safely drive to
and from the island. At the present time, the culvert on the
causeway is very deteriorated, and it is unsafe for vehicular traffic.
Staffwould like to develop aDesign/Build RFP to replace the
culvert.
There are a variety ofpre-constructed bridges that can be
purchased and installed at this location, and there needs to be some
decision making relative to the appearance and the functionality of
such a bridge. For this reason, staff would like to collect research
in this azea and present some of the options and findings to the
Pazks and Recreation Board for their input. After obtaining their
input, staffwill bring the RFP back to the City Commission for
their approval before seeking sealed bids.
At this time, we anticipate the cost of this project to be about
$70,000. Preliminary research has shown that the installation is
more expensive than the prefabricated bridges or culverts, and we
will seek vazious alternatives relative to the entire project for the
City Commission's review.
RECOMMENDATION: We recommend the approval for staff to develop aDesign/Build
RFP for the replacement of the culvert on the causeway to Pine
Island Pazk.

MEMORANDUM
March 5, 1999
TO: Timmy Johnson, Director of Recreation
George Worley, Community Development Dir.
FROM: Bob Kosoy, Director of Public Works ~~~
SUBJECT: Dutton Island Culvert
The existing culvert at Dutton Island has an opening which measures 6' x 9'4", and is
n corrugated metal pipe which is in very bad shape and the road has been closed due to
its structurally unsafe condition.
On March 5, 1999 we received the attached quotation from ConSpan for a precast
culvert/bridge at Dutton Road. The smallest section made by ConSpan is 12' wide,
and they are quoting on an arch shaped culvert 12' x 9' which would accommodate a
24' roadway. The total cost is $19,715, delivered to the job site. This price does not
include foundation work or installation, which the vendor estimates at $40,000-$50,000
additional. Therefore, a more appropriate budget price at this time would be
approximately $70,000.
