2 ADDENDUM NO. PROJECT NO PAGE ANSWERS TO QUESTIONS RECEIVED THROUGH :00 PM ON MAY 5, 08: Q# PBQs regarding Project 3-8-0: Reference 3 Concrete Walk is,870 SQ YD in the Bid Express file. The quantity in the plans is,870 SQ FT. Should the Unit of Measure be changed from SQ YD to SQ FT to reflect the correct quantity? A# The unit is correctly stated as SQ FT in the plans. The Commission revises the Bid Schedule of Items and the Estimated Quantities Worksheet accordingly through this Addendum No.. Q# Reference 73 Porous Backfill is 7 SQ YD in the Bid Express file. Typically this is bid by the CU YD. Could OTC please review and revise if necessary? A# The correct unit is CU YD. The Commission revises the Bid Schedule of Items, the Estimated Quantities Worksheet and Plan Sheet No. 3 of 7 accordingly through this Addendum No.. Q#3 For Ref. No. 5 Erosion Protection, please clarify what is work required for this item. Is there an allowance to be entered in the Lump Sum unit cost? Is a SWPPP required? A#3 This Project will not seek coverage under the Ohio EPA General Permit for storm water discharges from construction activities. As such a SWPPP is not required. However, Special Provision SP requires the Contractor to prevent and/or clean up the spillover of construction operations onto adjacent property, roadways, and waterways. Also under SP, the Contractor is required to submit a written proposal on specific environmental pollution control methods and measures to be employed which, would include the use of sediment and erosion controls and where those controls will be placed. Payment for the controls installed and properly maintained on the project is provided under Ref. No. 5 as Lump Sum to account for the various methods and measures available to control the construction site spill over. Compensation for this Item will depend on the Contractor fulfilling the approved plan and the proper installation and maintenance of the sediment and erosion controls used. Q# Do both existing bridges contain lead based paint? A# The Commission has insufficient information to form a belief as to whether either bridge is coated with lead-based paint. See Section.. of the Instructions to Bidders for the means available to schedule a site visit. Q#5 Would the OTIC consider Class QC concrete for the bridge superstructures and abutment slabs in lieu of Class HP concrete? Ready-mix concrete suppliers in this region are more confident producing Class QC. A#5 Class QC concrete is acceptable as a replacement for Class HP concrete at no additional cost to the Commission. The Commission will revise the Contract Documents accordingly in Addendum No.

3 ADDENDUM NO. PROJECT NO PAGE 3 Q#6 For Ref. No. 83 Falsework, Temp Bracing and Protective Structures, the approximate quantity in the worksheet is Lump Sum. Is it the intention to pay LS or should the quantity be changed to LS like all other LS items for this contract? A#6 The correct value is a single lump sum. The Commission revises the Bid Schedule of Items and the Estimated Quantities Worksheet accordingly through this Addendum No.. Q#7 Bid item 0- Conduit, Type F: The plans and bid item list calls this out as Item 6 but there is an SP6 specification in the proposal to connect to SP6 catch basins. Please verify if this is to be ODOT 6 or OTIC SP6 specification. A#7 SP 6 applies to this Work. The Commission revises the Plan Sheet 3 of 7, Bid Schedule of Items and the Estimated Quantities Worksheet accordingly through this Addendum No.. Q#8 Bid item - Aggregate Base: based on typical sections on plan sheet and 5, this quantity appears to be understated. Please review. A#8 The Commission revises the estimated quantity for Item SP 30 on Plan Sheet 3 of 7, Bid Schedule of Items and the Estimated Quantities Worksheet to 9 CU YD through this Addendum No.. Q#9 There is no subgrade compaction item for the Perrysburg-Holland approach roadways. Please add a bid item. A#9 The Commission adds Pay Item 0, Subgrade Compaction, to Plan Sheet Nos. 3 and 7 of 7, the Bid Schedule of Items and the Estimated Quantities Worksheet accordingly through this Addendum No.. Q#0 Bid item - Curb removed: most of this quantity is from Perrysburg-Holland Road, which actually has curb and gutter. Should there be two different bid items? A#0 The Commission divides, Item 0, Curb Removed, into Item 0, Curb Removed and Item 0, Curb and Gutter Removed. Plan Sheet Nos. 3 of 7, the Bid Schedule of Items and the Estimated Quantities Worksheet accordingly through this Addendum No.. Q# Plan sheet note under Seeding and Mulching lists eight work items related to Erosion Control. It appears they may be incidental to Seeding and Mulching. Considering these items may overrun/underrun, should these items have separate bid items?

4 ADDENDUM NO. PROJECT NO PAGE A# Seeded areas and associated erosion control measures shall be paid under Item 659 Seeding and Mulching, and all labor, material, equipment and incidentals are considered incidental to Item 659 per the note on Plan Sheet No. of 7. Q# Regarding topsoil, will the contractor be allowed to use topsoil from existing slopes or will the contractor be required to import/supply offsite topsoil? A# Any disturbed topsoil may be stockpiled for reuse. Q#3 Reference 70 qty Sealing of Construction Joints has a quantity of,676 LF. Plan sheets and 38 shows,03 LF for MP 59 and 57 LF for MP 8.. This totals,777 LF. Please review and clarify or revise the bid quantity. A#3 The 03 LF appearing for the structure at MP 59 is incorrect. The correct quantity is,0 LF. Therefore, the,676 LF provided at Ref. No. 70 is correct. The Commission revises Plan Sheet accordingly through this Addendum No.. Q# The estimated quantities for Item 7 Asphalt Concrete Intermediate Course, Type and Item 8 Asphalt Concrete Surface Course, Type appear to be switched on the bid form. The quantities on the general summary appear to be correct. Can OTIC please provide clarification? A# The quantities for Ref. Nos. 7 and 8 are transposed. The Commission revises the Bid Schedule of Items and the Estimated Quantities Worksheet accordingly through this Addendum No.. Q#5 Could the existing bridge plans be made available online? A#5 The Commission provides the as-built drawings with this Addendum No. in accordance with Section.. of the Instructions to Bidders. A#6 Could the soil borings at bridge MP 59.9 Perrysburg Hollow bridge in order to price the pile driving and prebored holes adequately? A#6 The Commission provides the geotechnical report with this Addendum No. in accordance with Section.. of the Instructions to Bidders. Q#7 The Prebored Holes note on sheet 0/7 discusses preboring the abutment battered pile to avoid the existing piling in place. Based on the layout of the new/existing piling in the General Profile (Sheet /7) it appears that the pier piling have a higher probability of a conflict than the abutment battered piles. Also the quantities provided do not match up

5 ADDENDUM NO. PROJECT NO PAGE 5 with the # piles and length of piles. Could the bottom of the prebored hole elevations be provided? A#7 The Commission provides the geotechnical report with this Addendum No. in accordance with Section.. of the Instructions to Bidders. Q#8 There is no PCB setup for EB/WB to protect the traveling public from pier footer excavation, crane pile driving, and other pier work at MP59.0 Bridge. Could the OTIC add a bid item for Portable Concrete Barrier? A#8 The Commission will respond to this question in Addendum No.. Q#9 What costs are to be included under Bid item 5 Erosion Protection? The note on sheet /7 pertaining to Erosion Control discusses all cost being paid under Item 659 which is Seeding and Mulching. This item is setup as Item 670. Please clarify. A#9 The Post Construction BMP Vegetated Biofilters for Item 670 is paid under Ref. No. 5, Erosion Protection. Q#0 Sheet 9/7 Item 630 Signing Misc.: Additional Signs Ground Mounted, As Directed by the Engineer shows a quantity of 6 SF. The bid item and sheet 3/7 show 6 EA. Which is the correct unit of measure to bid this item? A#0 The Commission will respond to this question in Addendum No.. Q# Are pile points/shoes required due to the piling being driven to refusal on bedrock? If so, please add a bid item for this. A# The Commission will respond to this question in Addendum No.. Q# Ref No. 73 Porous Backfill w Geo Fabric has a unit of measure SQ.YD. Should this be a unit of measure CU. YD? Please clarify. A# The CU. YD. unit is correct. The Commission revises Plan Sheet 3, the Bid Schedule of Items and the Estimated Quantities Worksheet accordingly through this Addendum No.. Q#3 Plan sheet 9/7 describes shop painting the structural steel at Perrysburg Holland Rd and says the cost is included in Item 53 Structural Steel, Type. One major cost component is the field touch up at the crossframes, splices, nicks from construction and other areas. We are assuming field touch up is included in the structural steel item as well. The field touch up will require nearly as much MOT as field painting. Shop prime/field paint will give the

6 ADDENDUM NO. PROJECT NO PAGE 6 OTC a more superior product with similar cost as shop applied/field touch up paint. Would the OTC consider removing the shop painting/field touch up requirement and shop prime/field painting the structural steel? A#3 No. The Commission requires the application of paint as stated in the Plans. Receipt of Addendum No. Project No is hereby acknowledged: (Firm Name) (Signature) (Printed Name) (Date) BIDDERS MUST RETURN THE ABOVE ACKNOWLEDGEMENT OF RECEIPT OF ADDENDUM NO. WITH THEIR BID.
