MEMORANDUM
December 27, 2004
TO:
Michael C. Van Milligen, City Manager
AD
FROM:
Gus Psihoyos, Acting Public Works Director
SUBJECT: Fengler Street Bridge Reconstruction Project
INTRODUCTION
The enclosed resolutions provide for the acceptance of the construction contract for the
Fengler Street Bridge Reconstruction Project.
BACKGROUND
The Fengler Street Bridge was closed in August of 2001 after an inspection by City staff
and IIW Engineers & Surveyors, P.C., observed an accelerated deterioration of the
bridge deck and support columns. Large sections of the underside of the concrete deck
had fallen from the bridge onto the railroad tracks below. With sections of the bridge
deck in extremely poor condition, it was possible that a heavy load could cause
additional damage to the deck, making it unsafe for traffic. For these reasons and in the
interest of public safety, the bridge was immediately closed.
The Fengler Street Bridge Reconstruction Project included the complete demolition and
removal of the existing bridge structure and the construction of a new pretensioned-
prestressed concrete beam bridge in the same location. The existing bridge columns
were removed while the existing deep pile foundation were salvaged and incorporated
into the new structure.
The new concrete structure was constructed to current roadway and bridge geometry
design standards, including a wider 34-foot bridge roadway with an 8-inch thick
concrete deck. The bridge piers and abutment supports were reconstructed in the
approximate same locations. The new bridge has 5-foot wide sidewalks on each side of
the bridge with pedestrian sidewalks installed on both sides of the approach roadway,
which match into both bridge sidewalks. Due to the steep side slopes at each roadway
approach section to the bridge, the outside edge of the sidewalks on grade required the
installation of a pedestrian ornamental hoop railing along these sections.
Additionally, due to the steep side slopes at each roadway approach section to the
bridge, concrete vehicular barrier rail was installed, which extended towards both
Kerper and Garfield. The original asphalt roadway approach pavement was removed
and reconstructed with a concrete pavement, which match into Garfield and the Kerper-
Fengler intersection.
The substructure of the bridge was constructed to comply with both the horizontal and
vertical clearance requirements of the railroad. Railroad standards required that the
bridge piers be constructed with crash walls, which have been incorporated into the new
structure while utilizing as much of the salvaged deep pile foundation as possible.
MITIGATION MEASURES
Due to the excessive and unusual deterioration of the original concrete bridge deck
directly above the railroad mainline, staff had a full-depth section of the concrete deck
removed and sent to Construction Technology Laboratories, Inc., which performed a
petrographic examination and chemical analysis of the deck sample.
Based upon the results of the examination and analysis of the deck sample, the
findings were incorporated in the new concrete bridge design to prevent similar future
deterioration conditions. The new bridge was constructed with improved methods and
materials including; epoxy coated reinforcing steel in the bridge deck and support
columns; the inclusion of a slag admixture in the concrete mix design which will make
the bridge deck more impermeable to chloride penetration; and the construction of air
vents between the bridge deck and support beams which will aide in ventilating the
underside of the bridge and dissipate the heat of the locomotive engine exhaust.
ARCHITECTURAL ESTHETIC FEATURES
Other design components built-in into the Fengler Street Bridge project included adding
several architectural esthetic features to the new structure which include; incorporating
buff colored concrete to the vehicular barrier rail; installing buff colored decorative
concrete balustrade railings on the outside of both bridge sidewalks; and installing six
ornamental lighting fixtures to the bridge.
PROJECT SCHEDULE - COMPLETION INCENTIVE
Since the Fengler Bridge is such an essential link to the Kerper Peninsula, the
construction contract included an early completion incentive. If the project would have
been completed prior to the specified early completion date of June 15, 2002, the
contract included a $3,000 bonus per calendar day, to a maximum of $50,000.
The bridge was permanently open to vehicular traffic on June 28, 2002, which did not
qualify Taylor Construction for the early completion incentive. Conversely, the project
was fully complete prior to the specified late completion date of June 30, 2002, which
negated the imposing of liquidated damages.
All non-critical items such as the aesthetic components, bridge lighting, pedestrian
handrailing, sidewalks and landscaping were substantially completed by the specified
date of August 30, 2002.
RAILROAD COORDINATION
The project required extensive communication and coordination with the railroad, I&M
Rail Link, which allowed construction operations to take place within the railroad right-
of-way. The railroad also required that a railroad employee (flag person) be on-site
during construction to coordinate train schedules and site safety with the bridge
contractor, which the City hired directly. The final cost of the railroad personnel on-site
during construction was $3,970 which is less than the $15,000 initially estimated.
DISCUSSION
The Fengler Street Bridge Reconstruction Project has been completed by Taylor
Construction, Inc. of New Vienna, Iowa, in the final contract amount of $1,147,078.75,
which is a 0.8% decrease from the original contract in the amount of $1,156,824.81.
Acceptance of the construction contract was delayed while staff worked with the
contractor to resolve concerns regarding the aesthetic appearance of the concrete
approach barrier rail incorporated on the project. Taylor Construction agreed and has
performed the necessary repairs to improve the non-uniform appearance of the railing
profile. Staff has reviewed the aesthetic repairs and feels the work is in conformity with
the lines, grades, cross sections and dimensions, including tolerances as shown in the
contract documents.
RECOMMENDATION
I recommend that the City Council accept the improvements and the final contract be
established at $1,147,078.75.
