11. The existing bridge with the historical wall appears to have some structural issues. The video shows a crack in the wall over the culvert pipe on one side of the road. The condition of the wall on the opposite side of the road is unclear. The requirement to remove the existing asphalt and base will not be an issue. The effort to lime stabilize the subbase and place new base could be an issue. The vibration from the compaction effort could cause a failure of the wall. Temporary shoring of the wall may prevent overturning but will not stop damage to the wall caused by the compaction effort. Will the contractor be responsible for damage to the wall caused by the required compaction specified in the contract?

Answer: The pavement on the bridge including 20-feet pavement from the end of the bridge on each side shall be milled and over laid only.
