INTRODUCTION
The enclosed resolution is in reference to the public hearing for the Historic Shot Tower
Rehabilitation Project -Phase I.
BACKGROUND
Constructed in 1856 to manufacture lead shot ammunition, the Shot Tower is one of
only a few remaining shot towers in the United States, and the only one west of the
Mississippi River. As a unique structure of national significance (National Register of
Historic Places), it has been recommended that the City stabilize and rehabilitate the
Shot Tower.
~ The City has committed $320,000 for the rehabilitation and interpretation of the Shot
Tower as part of the America's River project at the Port of Dubuque. The City
commitment has been used to leverage a $295,000 Save America's Treasures grant
from the National Park Service (NPS) and a $100,000 Historic Sites Preservation Grant
from the State Historical Society of Iowa (SHSI) for the stabilization and rehabilitation of
the Shot Tower.
Competitive Sealed bids were previously received on the Historic Shot Tower
Rehabilitation Project - Phase I on August 12, 2009. However, the bids submitted were
significantly over the current available funding which resulted in all competitive bid
proposals being rejected.
Since that time, staff has worked with the contractors that submitted bid proposals to
review the various Phase I scope of work elements to evaluate where costs were higher
than originally estimated. Through this constructability review, staff was able to identify
value engineering components so that the Phase I improvements can be modified or
adjusted to meet the current available funding while identifying proposed improvements
that will need to be deferred to a later date when additional funding can be secured.
Staff also worked closely with both the National Park Service and the State Historical
Society of Iowa to review and approve the proposed modifications or changes to the
Phase I scope of work to ensure that the City's grant requirements are in compliance.
Based on the revised scope of the project, the Historic Shot Tower Rehabilitation
Project will now be handled as a three-phase project: Phase I -stabilization and
rehabilitation; Phase II -full-height, spiral interior stair and handrails; and Phase III -
observation deck enclosure and interpretation of the tower.
Phase I is designed to meet all of the City's grant requirements and involves the: repair
and restoration of the interior and exterior limestone and brick masonry surfaces; the
removal and replacement of the existing concrete cap with a new concrete cap and roof
hatch; add interior lighting and electrical improvements; and the installation of new wood
window, louver, and door construction.
Both the Phase II and Phase III projects will be deferred until such future date when
additional funding can be secured to develop the interior stair and the roof top
observation deck enclosure.
The architectural firm of Hasbrouck Peterson Zimoch Sirirattumrong (Chicago, Illinois)
has developed the plans and specifications for this work and will provide assistance
during the bid-letting and construction phases of the project.
RECOMMENDATION
I recommend approval of the plans, specifications, form of contract and the estimated
cost for the Historic Shot Tower Rehabilitation Project -Phase I.
BUDGET IMPACT
The estimate of probable cost for the Historic Shot Tower Rehabilitation Project is as
follows:
Proiect Cost Estimate
Construction Contract $ 536,500
Contingency (10%) 53,650
Consultant -Archeological Survey 37,212
Consultant Fees (Architectural & Engineering) 57,400
Grant Administrative Fees 15,000
Total Project Cost 7 2
The funding for the Historic Shot Tower Rehabilitation Project will be as follows:
CIP No. Fund Description Fund Amount
7001854 Save America's Treasures Grant $ 295,000
1001854 Historic Sites Preservation Grant 100,000
1001854 HRDP Grant 15,500
1001854 Historic District Public Improvement Project ~ 100,000
7001854 General Fund 204,762
Total Project Funding ~
The City currently has a maximum budget of $786,355 for the Historic Shot Tower
Rehabilitation, which leaves approximately $87,000 in reserve to cover any additional
unforeseen costs that may develop during the rehabilitation work.
ACTION TO BE TAKEN
I respectfully request that the City Council adopt the attached resolution approving the
plans, specifications, form of contract and the estimated cost for the Historic Shot Tower
