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.
