May not be as it appears, once again…
Just a few months ago, Citizens for Our Bridge couldn’t get the WisDOT to paint any more than 5′ above the road bed in the bridge rehab plan. They claimed that even the over-coating option was not needed and the existing paint was in good shape. Now, just a month from letting out bids, they want to take painting to an extreme, spending much more money and extending the downtime significantly into another summer season, while possibly pushing the project over budget. These proposed changes will intentionally add millions - with no plan to apply for stimulus money, leaving the painting unfunded. The explanation provided is a plan to pay for it out of the general fund. Really?
How can the state now afford to spend millions more than what has already been budgeted for this project? Can we afford to let them try? What will happen if they can’t? Is the plan to restore the main bridge connecting the heart artery of our major commercial and industrial zone being intentionally set up to go over budget… just as Senator Alan Lasee and Leo Zipperer predicted might happen in their oppositional letters? And are these NEW million dollar changes and expenses being included without adding them to the new rehab budget cap? Who’s delaying progress here? Who’s ignoring safety concerns? Who’s negatively impacting our economic base? Who are “they” and what do they want?
Read on…Last week the WisDOT strategically introduced “new plans” to extend out the rehab for much longer than necessary. YES, for another whole season as it appears, and for no GOOD reason and in conflict with their own report. Tony Depies, Sturgeon Bay city engineer again agrees that this new plan is a good idea, with no concern for the economic impact on our community. Out of the blue and contrary to the state’s own report, they are now adding encapsulating, sandblasting and painting the entire bridge structure, to be undertaken AFTER all construction is complete, not during. They are also adding the removal, instead of the recommended rehabilitation, of the entire segmental girders, when only spot-replacement of smaller parts is recommended in their report.
Why is the WisDOT ignoring their own BRW Rehab Inspection Report now and adding new out-of-budget additions, just 1 month before going out to bid?
Tony (City Engineer) says; “I have cruised through the (BRW) document very quickly and actually want to thank you because it seems very comprehensive and well done.”
Abba Lichtenstein (world renown bridge expert) says; ” If the segmental (rolling girders) are sound why are they being replaced? No need for an engineering genius to explain.”
BRW, Inc. (bridge inspection experts) say in their report, created after testing the Bridge, “The existing lead-based paint system is a long lasting one that is generally in good condition, especially above the roadway splash zone. It is capable of continuing to provide protection to the underlying steel for many additional years and the sand-blast removal alternative is therefore not recommended.”
Please WisDOT, with all due respect, we need proof that these changes and subsequent further delays are “needed” before rubber stamping it and moving forward. We need to ask why the most recent “replace, instead of repair” changes to the plan have been included and why an “over-kill paint job” is being added at great expense ($3 - $4 million) to this project. If we have an ounce of concern left for the merchants downtown or our own citizens’ safety, why not follow through with accomplishing the spot-painting, out of season and during the construction phase? Yes, the community would gain a whole summer season and the state would save millions. Why is that no longer a major concern? Spending more time and money than necessary on this project, in this particularly tight economic climate is suspect for concern.
Our historic downtown is dying after a two year street project (that could have been done in just a few weeks) and local merchants need this bridge rehabbed and reopened as soon as possible. The accidents in the downtown area have risen to an all time high and, at the same time we have the funding for the REHAB if we simply follow the original plan. We need to support what’s best for the city by wrapping this up in 10 months as planned instead of adding on 6 months to a year and spending $2 - $3 million dollars more.
BRW In-Depth Inspection REPORT states:
Paint SystemThe previous paint system on the approach span trusses was removed by sandblasting in 1984. The bridge was then re-painted with a coating system that included a lead-based primer. That paint system has performed well and is still on the bridge. The condition of the paint on those members above the roadway splash zone is generally good. There are some localized areas of paint loss on the upper chords (See Photo S34). Within the roadway splash zone, there are some localized areas of corrosion, especially at connections. As was previously described above in the sections on Truss Lower Chords and Floorbeam End Connections, there are areas of corrosion and significant pack rust in the truss lower chords and floorbeam connections to them. The floorbeams themselves and most of the stringers on each of the trusses are in good condition (See Photo S35). This is because of the protection that the deck above has provided.
Localized areas of coating failure throughout the trusses, which is most predominant in the splash zone, should be machine-tool cleaned and locally re-painted as part of a ten-year or twenty-five year rehabilitation of the bridge. This repair of local paint deterioration does have a limited lifespan and would need to be performed several times over an additional period of twenty-five years of bridge service.
Alternatives to machine tool cleaning and re-painting local areas of paint deterioration for a twenty-five year bridge rehabilitation include the following:Providing an encapsulating paint system over the existing paint for the entire bridge. Providing an encapsulating paint system would be substantially more expensive than local machine-tool cleaning and painting but it would be less costly than blast blast-cleaning and then re-painting the entire bridge. However, for an encapsulating overcoat paint system to be effective, the existing paint system that will underlie it must be tightly adhering to the base-metal. Adhesion tests were performed on the existing paint system of the trusses at random locations. Results from these tests varied from nearly no loss of adhesion (See Photo S36) to nearly complete loss (See Photo S37). Additional testing of the existing paint and consultation with several coatings manufacturers would Michigan Street Bridge over Sturgeon Bay BRW, Inc. be warranted before deciding to overcoat-paint the bridge steel instead of locally machine toolcleaning and painting areas of deterioration.
Sand-blast cleaning and re-painting the entire bridge. Complete removal of the existing lead based paint system by sand blasting would require confinement of residues and related abatement measures both above and below the deck. It would have to be done with the bridge closed to traffic. Based upon information obtained during a subsequent site visit in February of 2001 with the contractor who previously sand-blasted and painted the bridge in 1984, the existing lead based paint system is a long lasting one that is generally in good condition, especially above the roadway splash zone. It is capable to continuing to provide protection to the underlying steel for many additionalyears and the sand-blast removal alternative it is therefore not recommended.
Please ask the WisDOT to quit playing games with the public, using huge budgets and extended delays on this important infrastructure project. They know this will open debate again and risk the preservation and reopening of this vital link.
