There is no way for the contractor to realistically estimate the cost of this work and carry it as incidental to the pertinent items. A1: See revised note on sheet 44 Q2: October 31, 2014 at 11:52:11 AM: Concerning cast stone requirements for Part 3. The plan note on sheet 215 states that Cast Stone units shall be manufactured within 500 miles of the Project Site. Both specified manufactures, ARRIS.cast (production facility: Forty Valley, GA 750 miles) and Haddonstone (production facility: Pueblo, CO 1,300 miles) do not meet this Specification. Is the contractor to use only these two manufacturers, (even though they are both outside of the 500 mile range) or will other manufacturers be allowed? A2: The distance requirement has been removed. See revised sheet 215 Q3: October 30, 2014 at 5:35:21 PM: Where can we access a copy of the Geotechnical Subsurface Investigation Retaining Structures Report referenced on page 757..? A3: The geotechnical report referenced does not exist. This note will be deleted from the plans. See revised sheet 757 Q4: Tuesday, October 14, :00 AM: Plan sheet 61/1771 shows temporary shoring. The note on the same page states that the temporary shoring is to be paid for under 503 Cofferdams and Excavation Bracing. There is no bid item for this work. Please add a bid item in the next addendum. A4: See additional pay item above Q5: October 31, 2014 at 8:31:22 AM: 1. Please provide more detail for Section A shown on sheet 748/1771. Section A indicates that the upper third of the retaining wall for Ramp NC-2 should be backfilled with low permeability embankment fill. Section A also indicates that the quantity of L.P.E.F. is included with the roadway quantities. Currently this volume of material is included with the roadway quantiies as embankment as there are no bid items setup to place low permeability embankment fill in the Roadway quantities. Please clarify whether or not the detail for the retaining wall is correct or the cross sections and bid items in the roadway items are correct. A5: The backfill detail for Wall 102 is correct. The roadway earthwork quantities adjacent to Wall 102 will be revised in the next addendum to reflect the geofoam shown in the wall plans, and the estimated volume of low permeability embankment fill will be provided. See revised sheets 0019, 0027, 0398, 0399, 0432, 0549, 0550, 0623

7 Q6: Mon 10/27/2014 6:25 PM: Addendum #6 revised several concrete sealing items to be As Per Plan (Ref. 423, 480, 510, 528, 558, 593, 628, 655, 800, and 842) and added a note stating that permanent graffiti protection was to be included in each item. This is also the case for Ref. 447 mentioned in the previous question. This adds significant cost to these bid items. ODOT normally bids graffiti protection as a separate bid item. In order to avoid confusion and bidding mistakes, please add bid items for permanent graffiti protection instead of making it incidental to Epoxy-Urethane sealing. A6: This will be modified in the next addenda to an additional item 512E75500 Sealing Misc.: Permanent Graffit Protection. The total for the 12 structures is approximately SQ YDs. Q7: 10/22/2014 8:43:40 AM Please confirm the use of polymeric sand for Bid Item 1162: Misc. Recycled Brick Pavers. The details shown on sheet 188 of 234 appear inconsistent. Detail 1 shows using polymeric sand while details 2 and 3 shows using screenings. What material is required? A7: Detail #1 is correct. Q8: Wed 10/15/2014 4:10 PM: After numerous unanswered and unreturned calls to Toledo Edison in regards to the cost to de-energize the 69 kv lines we request ODOT set up an allowance item for de-energizing the lines. There is no way for the contractor to realistically estimate the cost of this work and carry it as incidental to the pertinent items. A8: See revised note on sheet 44 Q9: Tue 10/14/2014 2:29 PM: Part 1, reference mm surface course, calls for 3 cy of material on Detroit Ave. The Part 1 office calcs show 3 cy of 19mm PG70-22 intermediate course on Detroit Ave. Sheet 261/1771 says to see Part 3 for Detroit Ave work. Part 3, sheet 55/234 says to see Luc-Detroit Ave for the adjoining project. What are the 6 cy of material on Detroit Ave for? A9: Part 1 plan sheets 35 and 261 show the removal and replacement of a 3-foot width of existing pavement, curb & gutter and 5-foot wide sidewalk along the westerly side of Detroit Avenue to remove the existing bridge pier and construct the foundation of pier #20 for the proposed LUC L/R bridge. The total 6 CY of asphalt surface and intermediate course is for that pavement replacement.revised sheet 261 is attached Q10: Tue 10/14/2014 1:59 PM: Phillips Ave, Part 1 calls for a 448 Type 1 surface course.
