Ohio Department of Transportation - Prebid Questions Project No. 140535 FAI-76938 - -US 33-05.60(Carroll Area) Question Submitted: Sale Date - 12/11/2014 12/1/2014 11:13:26 AM RE: 203 Roadway Misc – Sand Blanket. Most local natural sand has carbonate content much greater than 10%. We would expect to have to get natural sand from the northeast corner of Ohio to meet the <10% requirement. Will the department either just leave the specification to simply say “natural sand”, or specify a set Carbonate content and also the test method that we would need to follow for approval. Question Submitted: 12/1/2014 11:13:21 AM RE: Supplemental Spec 840 Date. Sheet 770/1003 references Supplemental Spec 840 dated 04/20/2012. Could this be updated to the 07/18/2014 spec?

Plan sheet 922 details pile furnish lengths for the piles at the Rear Abutment, Pier 1, Pier 2, and the Forward Abutment. The notes for the pile design loads on plan sheet 924 list pile order lengths for these piles at the same locations. The lengths detailed on sheet 922 do not correspond to the lengths listed on sheet 924. Please review. Question Submitted: 12/1/2014 11:12:54 AM RE: Bridge No. FAI-33-0656A - Pile Driving Constraints. The pile driving constraint notes, found on plan sheet 924, state that prior to driving piles, the contractor is to construct the spill through slopes and the bridge approach embankment up to the level of the subgrade elevation for a minimum distance of 200 ft. behind each abutment. The note then states that abutment excavation and the installation of the abutment and pier piles shall not occur until a minimum of 30 days to 60 days maximum after the required embankment has been constructed to allow proper settlement. To ensure that all contractors are preparing their pre-bid schedules with the same constraints, please specify a single duration to assume for the waiting periods at the abutments of the FAI-33-0656A bridge. *** DISCLAIMER - Prebid questions and answers provided are for informational purposes only and are not part of the Bid Documents.

Also please specify how the rebar in the pilings are to be connected to the concrete foundations. Is the intent to have rebar hooks protruding from the tops of the C.I.P. piles? Question Submitted: 12/1/2014 9:26:04 AM REF # 438 is called out as 1/2" x 8" x 60 FT bearing in the EBS and proposal for bridge FAI-33-0637A. The plans call this out as 1 1/2" thick. What thickness is correct, 1/2" or 1 1/2"? Question Submitted: 12/1/2014 9:24:11 AM Please clarify the bearings on Bridge FAI-33-0656. The EBS and proposal call out REF #465 & #466 to be 1/2" x 8" x 56 (57) FT. The plans call these bearings out as 1 1/2" thick. Are the bearings to be 1/2" thick or 1 1/2" thick? Question Submitted: 12/1/2014 9:18:04 AM Plan sheets 894 and 896 show footer details on the foundation sheet for bridge FAI-33-0656 with rebar in the 16" pile. They are detailed as 8-RA601 & 8-FA601. There is no detail for this and no listing in the bar schedule for these bars. We believe these bars are not needed as the 16" pile are in abutments with no exposed length. Can ODOT please clarify? If the bars are required can ODOT please provided more detail with dimensions as well as where these bars are to be paid? Question Submitted: 11/26/2014 8:38:10 AM Per SCD I-2.1, I-2.2, and I-2.3, an expansion joint is required at each end of the 20' inlet barrier section. Per RM-4.3 and RM-4.5, a reinforced end anchorage is required at interruptions in barrier caused by expansion joints. Will reinforced end anchorages be required adjacent to the inlet barrier expansion joints? They do not appear to be included in the plan quantity. Reinforced end anchorages will be required adjacent to the inlet barrier expansion joints. Please see forthcoming addendum with revised sheets and quantities. Question Submitted: 11/25/2014 10:06:19 AM RE: 203 Roadway Misc – Sand Blanket. The material requirements listed on sheet 766 of the plans state that the sand shall be natural, non-carbonate material, generally conforming to Item 203 granular material type B (703.16) with no more than 5 percent passing the #200 sieve. What is meant by the term “non-carbonate material”? All natural sands have some limestone in them that is calcium or magnesium carbonate based. Is the department asking for silica sand? We don’t necessarily need silica sand. Most natural sands in this area have small carbonate percentages. The intent is to prevent a crushed limestone product from being used. It is not necessary to specify silica sand as long as the carbonate fraction is minimal (say less than ~10%) Most locally quarried sands do not have a high carbonate fraction and would be considered acceptable for our purposes and will provide the Contractor some flexibility. Question Submitted: 11/25/2014 10:04:49 AM RE: Topsoil Quantity. Plan sheet 782 shows topsoil to be placed around MSE Wall E with a thickness of 2 feet. Plan Quantity is 1,118 cy. Is the thickness and quantity correct? Yes, both thickness and quantity are correct. Question Submitted: 11/24/2014 2:29:43 PM The plan note for Item 203 Roadway Misc.: Sand Blanket on sheet 766 calls for material conforming to item 203 granular material type B (703.16). Is this referring to 703.16 B Granular Embankment Materials or 703.16 C. Granular Material Type B? If I you are calling for material per 703.16 B Granular Embankment Materials please provide a gradation for this material. If you are calling for 703.16 C Granular Material Type B the material gradations that are specified per this item are not “sand” materials. It is assumed that the intent is for the placement of a 2’ blanket of natural sand. If this is the case please provide a gradation for the natural sand to meet. Sand blanket material should conform to 703.16 B. Granular Embankment Materials. Provide gradation as per 703.02 A. Fine Aggregate.

Question Submitted: 11/19/2014 10:47:16 AM Is the section of Ramp B from station 315+50 to 317+00 to receive the wick drains and preload or is the overexcavation and refill the only remediation to be performed in this section? **This answer superses the first answer to the same question submitted on 11/14/14 10:15am** The section of Ramp B from station 315+50 to 317+00 will not receive the wick drains but will require pre-loading. Please see forthcoming addendum for revised sheets and quantities. Question Submitted: 11/19/2014 8:50:56 AM Please consider allowing a maximum of 30 days for the closure and detour of the Winchester Road, Connector West, Carroll Southern Connector, Carroll Southern Road and Ramp D A+B segment. The amount of work and wait periods for stabilization and concrete pavement will make it difficult to complete these areas in the allotted time especially with the construction of the box culvert at Carroll Southern Road. The closures will remain 20 days. However, the closure of Winchester and Carroll Southern will be separated into two segments for A+B bidding purposes and to allow for the closure to be performed together or separate. This will be revised with a forthcoming addendum. Question Submitted: 11/19/2014 7:38:17 AM The quantity for item 840 Foundation Preparation appears to be overstated, please verify this quantity. Is the area under the soil embankment, paid under the MSE wall items, included is the foundation preparation quantity? Will the 1’ of granular material type C placed on the subgrade of the wall excavation area be paid under the pay item for 203 Granular Material Type C or is it incidental to the 840 Foundation Preparation? In sections where the soil embankment is islanded by MSE wall embankments, the items under the soil embankment are carried with MSE wall items. In sections where the soil embankment is bounded only on either the left or right side by MSE wall embankment, the items under the soil embankment are carried with roadway items. The 1 foot of granular material type C placed on the subgrade of the wall excavation areas, where shown, is carried for payment under the item for 203 - Granular Material, Type C. This material shall be installed/placed according to SS840, which references C.M.S. section 204. The placement requirements, as described by SS840, are incidental to Item 840 – Foundation Preparation. Please see forthcoming addendum for item 840 Foundation Preparation quantity modification and sheet revisions relating to this prebid question. Question Submitted: 11/18/2014 1:53:02 PM RE: Oil Spill Kit. What is to be included in the oil spill kit? Is the contractor responsible to perform oil spill cleanup if required?

No, SIP forms will NOT be allow for this project. Question Submitted: 11/18/2014 1:52:55 PM RE: Winchester Road, Connector East, Carroll Southern Connector and Ramp D Intersection Closure. In some places the Maintenance of Traffic notes on p. 54 state that Winchester Rd and Carroll Southern will be detoured for 30 days, but within the same note it also states that the detours will be for a period of 20 days. Should the note list the same number of days throughout with the intent to close/detour the Winchester Rd intersection and the Carroll Southern Intersection at the same time? Or, can the Winchester Road intersection and Carroll Southern Road intersection closures/detour occur independent of each other? If the Winchester Rd intersection and Carroll Southern Rd intersection are closed at separate times, should there be 2 separate A+B tables; one for Winchester Rd and one for Carroll Southern? Please Clarify. The notes on sheet 54 with respect to the A+B bidding for Winchester and Carroll Southern will be revised with a forthcoming addendum to be 20 days. Also, separate tables for each intersection will be provided on sheet 54 with the intent that these closures can occur together or separate. Question Submitted: 11/18/2014 1:52:50 PM RE: Final Completion Date Requirements. The final completion date requirement note on p. 55 states that extensions of time will be… in accordance with C&MS 108.06 except; No extensions will be granted for material delays, labor strikes, and inclement weather except in extreme situations. Does this mean that C&MS 108.06C including Table 108.06-1 does not apply? The note on sheet 55 regarding extensions of time will be removed with a forthcoming addendum. Question Submitted: 11/18/2014 1:52:41 PM RE: CPM Schedule and Earthwork Waiting Periods. The pile driving constraint notes, found on plan sheet 830, state that abutment piles may not be driven to the Ultimate Bearing Value until the required MSE walls and embankments have been constructed and a minimum of 30 days to 60 days maximum waiting period has elapsed. The notes go on to further state that the Engineer may adjust the length of the waiting periods based on settlement platform readings. To ensure that all contractors are preparing their bids with the same CPM schedule constraints, please specify a single duration to assume for the waiting periods at the abutments of the FAI-330637 bridge. See forth coming addendum for prebid meeting notes. Question Submitted: 11/18/2014 1:52:04 PM RE: Bridge No. FAI-33-0637 – Abutment Piles. The notes for the abutment piles on plan sheet 830 reference 12 each piles at the Rear Abutment and 14 each piles at the Forward Abutment. The piling layout, found on plan sheet 834, details 28 each piles at the Rear Abutment and 26 each piles at the Forward Abutment. Additionally, the quantities set up for Reference Items 395 and 396 support the number of piles shown in the piling layout on sheet 834. Please revise the notes on plan sheet 830 accordingly. See forth coming addendum for sheet 830 revision. Question Submitted: 11/14/2014 3:55:14 PM Can ODOT provide addtional geotechnical information for the preloading and special construction area at Ramp B/Connector West?

Question Submitted: 11/18/2014 4:00:12 PM WZ Sheet Piling: The majority sheet piling shown on sheets 83-121 is detailed in other sections of the plan set and have bid items associated with them. There is sheet piling shown in the MOT plan which does not have a bid item (i.e. WZ sheeting along NB 75 STA 422+25 LT to STA 429+80 LT). Since this sheeting is for MOT purposes, is it to be paid in the LS MOT item or should a new bid item be added? Question Submitted: 11/18/2014 8:13:59 AM The plan notes for Bridges LUC-75-0724, LUC-75-0807L/R, and LUC-75-0817L/R indicate that the pipe piling is to be ASTM A572. This is not a grade of steel for pipe. Normally A252 material is used. Please clarify. ASTM A 252, type 2 should be furnished for steel pipe piles (per CMS 711.03). will be addressed in a future addenda Question Submitted: 11/17/2014 11:04:53 AM Plan sheet 28/883 has a note stating that "The decision to remove or leave in place the WZ sheet piling shall be approved by the engineer, in writing." This note appears in 4 locations on this plan sheet. The contractor has to either include the cost of leaving the sheet piling in place or remove the sheet piling. What is the intent of this note? If the intent is to leave the sheet piling in place a bid item should be added by addendum. The notes should also be revised. *** DISCLAIMER - Prebid questions and answers provided are for informational purposes only and are not part of the Bid Documents.

Please clarify that rock excavation will also be paid if encountered during 204 Excavation, 605 Underdrain and 611 items as well. It is not expected to get into rock, but if rock is encountered during the excavation operations of these items, the additional cost of excavating the rock will be done by change order. Question Submitted: 10/13/2014 4:58:43 PM Looking at the schedule for the waterline phasing and the interim completion dates. Would ODOT consider the trench repair to be completed with 255 concrete repair rather than asphalt given the time this work could be performed and decrease the impact on the traveling public? Same question applies to the Pavement for Maintaining Traffic APP. Page 12/145 shows the course make-up but this could delay the possible start time of the project if asphalt must be used. The contractor will be allowed to use concrete in leiu of asphalt, however, the subsequent additional costs of milling of this concrete will be at the contractor's expense. An addendum will be processed to allow this varience in the specification item. See Addendum No. 1. Question Submitted: 10/13/2014 4:48:58 PM Page 9/145 discusses proof rolling the stabilized areas per 204.06. Given the width and length of the apparatus conforming to 204.06, it will not be possible in many of the widening areas to be used. Add in the drive access to be maintained constantly and the phasing of each area that must be brought up to 5” drop off each day. Not to mention the shallow utilities that will be exposed at this excavation depth with the weight of this unit, would ODOT consider waving the 204.06 spec on the project? The Engineer will review the areas in question and non-perform areas that are not feasible to proof roll.

Monday, December 01, 2014 3:11:48 PM Page 14 Ohio Department of Transportation - Prebid Questions Question Submitted: 11/19/2014 2:42:29 PM Regarding the Item Special – Structure. Misc.: Moisture Release Deck Coating and Slip Resistant Deck Coating page 168/201 - the material suppliers for the 2x8 IPE Wood decking do not recommend a moisture release coating to be applied to this type of wood material. Due to the nature of the hard dense material properties of the IPE wood the moisture release coatings do not adhere to the decking well and will have a tendency to peel off. The plans also call out for a slip resistant coating to be applied to the decking surface once the moisture release coating is applied. If you put moisture release coating on the deck the concern is the slip resistant coating will not adhere to the sealer making the slip resistant coating an ongoing maintenance issue. Will you eliminate the moisture release coating portion of the note in consideration of these concerns? A forthcoming addenda will address this prebid. Item 530E00800 - STRUCTURE, MISC.: MOISTURE RELEASE DECK COATING will be eliminated. Question Submitted: 11/14/2014 8:46:28 AM On P-168/201, Item 513 Structural Steel paragraph 1.6 indicates an AISC certified steel erector (CSE) to be used for the erection of the structure. According to our information, there are only 3 ODOT qualified Ohio contractors qualified as a CSE. Is Level 2 bridge construction qualification enough to meet this requirement? If not, could this requirement be waived and Level 2 approved for steel structure erection? A Level 2 bridge qualification is adequate for the erection of the prefabricated truss.

Given the original scope and information released by addendum #1, there does not appear to be sufficient time to complete the contract work. See forthcoming addendum.The completion date will be revised to 9/30/15. Question Submitted: 11/21/2014 7:47:46 AM With the replacement of the pavement removal and asphalt concrete base items with 253 pavement repair, should the pavement repair item include the 16.5" full depth repair with replacement by 13.25" of 301, 1.75" 19mm, 1.5" 12.5mm? Would the department consider 16.5" of 301 base to be placed in 3 lifts? Removal of concrete and asphalt and replacement with 5 compacted lifts severely limits production given the permitted lane closure times. The pavement repair is to include 16.5" of item 301 per the Addendum 1 revised pavement repair detail on sheet 5. Tag 24 states to install 16.5" of item 301 in 3 lifts. Question Submitted: 11/20/2014 3:47:25 PM Our question for the jacking item was in error. Please add a jacking item for Bridge 275-1819 Pippin Road for the abutment bearing replacement.

Monday, December 01, 2014 3:11:48 PM Page 15 Ohio Department of Transportation - Prebid Questions Question Submitted: 11/18/2014 4:22:15 PM Please add a jacking item for the HAM-275-1684 bridge Struble Road for the bearing removal/replacement. A jacking pay item is already included in the plans and proposal. See proposal reference number 0107. Question Submitted: 11/17/2014 4:08:14 PM For structure HAM-275-2016 Mill Road, there is an item for Patching Concrete Bridge Deck Overlay with Micro-silica Modified Concrete. Typically curing times for a micro-overlay is 72 hours. This bridge is supposed to have one lane of traffic maintained at all times using flaggers. Will ODOT allow a 1 week closure of this bridge to facilitate this work, or will another material such as Type B bridge deck patching be specified with a rapid set bag mix material? See forthcoming addendum.The Item 519 Special - Patching Concrete Bridge Deck Overlay with Micro Silica Modified Concrete pay items for structures HAM-275-2016 and HAM-275-2027 will be replaced with Item 519 Special - Patching Concrete Bridge Deck Type B. Question Submitted: 11/17/2014 3:53:09 PM For the HAM-275-1684 structure the removal will consist of all end cross-frames which we agree with as stated on the note on sheet 65. Additionally we think that a few intermediate cross-frames may need removed due to the large skew angle and these cross-frames attach to the beam on one end inside of the area that would be encapsulated the new diaphragm concrete. Is ODOT ok with this removal as it will be necessary for concrete formwork and placement. We don't think this will happen in every bay, but will occur in at one or two locations. See forthcoming addendum.The note with heading "Item 202 - Portions of Structure Removed, Over 20 Foot Span, As Per Plan" will be revised by adding the text "intermediate crossframes that conflict with abutment diaphragms" to the first sentence of the first paragraph. See addendum for details. Question Submitted: 11/17/2014 2:52:57 PM Will ODOT please consider a 90 day closure for the re-deck bridge. This bridge is long with a large skew over top of 275. This will require night time demolition work that cannot be double shifted or pick up any time to meet such a tight schedule. Additionally the skew will create extra days of work with demolition. Furthermore, the bridge requires a deck pour with the diaphragms at the same time. Curing must take place before backfilling the abutments can take place. This means the approach slabs cannot be poured for at least 5 to 10 days after the deck. After the approach slabs are poured you must have cure on them, sidewalk pours, then railing pours, then install metal railing and vandal fence. You have 28 days of cure in the job with working time in between. To build and open this bridge with the extra sidewalk/railing pours, railing and vandal fence and still meet curing strengths and requirements is not feasible. Please consider a 90 day closure.Additionally please consider extending the completion date to sometime in October of 2015. This job will require lots of lane closures/traffic zones for asphalt as well as bridge work. The asphalt resurfacing will be going on at the same time as the bridge work; however, when bridge striping and painting are happening zones will have to be coordinated and could take additional days as both bridge painting and asphalt paving cannot happen at the same location during the same time frames. For this scheduling issue will ODOT allow more time for this contract. See forthcoming addendum.The project completion date will be revised to 8/15/15.The 60 day closure will not be revised. Question Submitted: 11/14/2014 3:54:16 PM Will the existing bridge drawings be made available? ftp://ftp.dot.state.oh.us/pub/Contracts/Attach/HAM-82972/Reference%20Files/ Question Submitted: 11/14/2014 2:15:57 PM The department's response to the question submitted 11/11/14 9:53:48AM indicates that the 3.25" of item 448 are calculated on sheet 39 of the plans. This sheet only includes item 442 mixes. If 442 mixes are to be used, does the calculated total account for double the quantity for the repair area of 18,860? The 3.25" as installed during pavement repairs will be removed as part of the pavement planning operation and replaced permanently a second time as part of the intermediate and surface course installations. The Item 442 Intermediate and Surface courses were calculated once. The previous prebid question (11/11/14 @ 9:53:48 AM) response incorrectly stated Item 448 instead of Item 442. *** DISCLAIMER - Prebid questions and answers provided are for informational purposes only and are not part of the Bid Documents.

Monday, December 01, 2014 3:11:48 PM Page 16 Ohio Department of Transportation - Prebid Questions Question Submitted: 11/14/2014 2:06:46 PM Would the department review the possibility of 302 asphalt base to be used in lieu of 301 base for the pavement repair? At 16.5" depth to be put back under running traffic each day, the use of 302 may help alleviate some of the anticipated occurrences of this issue. The Department has considered the use of Item 302 in lieu of Item 301 and determined there will be no change from the plan requirement to use Item 301. No addendum necessary. Question Submitted: 11/14/2014 1:25:09 PM The 80 hours for Law Enforcement Officer seems very low for this project. Could the department review this quantity? See forthcoming addendum.The quantity for Law Enforcement Officer will be increased to 600 hours. Question Submitted: 11/14/2014 1:23:33 PM Can traffic run on the milled surface? See forthcoming addendum.A note will be added by addendum stating traffic will not be allowed to run on the milled surface. Also all pavement markings will be placed prior to opening to traffic. Question Submitted: 11/11/2014 10:24:51 AM There are not any pay items for work zone pavement markings. How will work zone pavement markings be paid for? See forthcoming addendum. Work zone pavement marking quantities will be provided. Question Submitted: 11/11/2014 9:56:52 AM How will the tack of the vertical surfaces be paid for in the areas of pavement repair? Tack is not incidental to either pavement removal or 301 base. See forthcoming addendum.The 202 Pavement Removed and 301 Base Course pay items for I-275 full depth pavement repair work will be deleted and replaced with a 253 Pavement Repair pay item. The application of tack to the vertical surfaces is covered in the 253 pay item. Question Submitted: 11/11/2014 9:53:48 AM The plan note for full depth pavement repair states to remove 16.5” of existing pavement and replace it with full depth flexible pavement. The calculations on sheets 23-38 show placing 13.25” of asphalt. The plan note states full depth four times, but the calculations only have the contractor replacing partial depth (13.25” of 16.5” of depth). Is the contractor to place full depth flexible pavement as stated in the plan note? Yes. The contractor is required to place full depth pavement of 16.5”. The I-275 pavement repair includes 1.50” of Item 448 surface course and 1.75” of Item 448 Intermediate course over the length of the I-275 project. This quantity is quantified in the pavement calculations sheet 39 in the MAINLINE I.R. 275 row. The calculations on sheet 23-38 tabulate the quantities (pavement removal and 13.25” of Item 301) in the full depth pavement repair locations beyond the standard 3.25” of Item 448. The I.R 275 Full Depth Pavement Repair Detail on sheet 5 shows the required buildup in the full depth sections and is consistent with the General Note on sheet 9 and the pavement calculations. Question Submitted: 10/30/2014 10:45:00 AM Regarding the asbestos bid item, how is the contractor to reasonably bid an item that was inaccessible and unforeseen? There may be no asbestos present or every inch of the bridge may contain asbestos. If there is no asbestos and the contractor bids $10,000 the contractor is entitled to that money as they handled anything that may have been present and ODOT is paying for a service never received. If the bridge is covered with asbestos then the contractor will loose lots of money. Being that this is completely an unforeseen item that has no reasonable ground for bidding would ODOT please consider this work as extra work to create an even bidding playing field as well as a fair way of being compensated for the work. I.E. no one's bids are distorted and ODOT only compensates the contractor for actual amounts of work done. See forthcoming addendum.The Asbestos Abatement Lump Sum pay item will be deleted. The note will be modified similar to the following (see addendum for exact wording): Per an asbestos survey, the District has no indication that asbestos contaminated material (ACM) is present. Should the Contractor encounter ACM that was not found due to limitations in survey conditions, the handling and disposal of said ACM will be covered under CMS 202.04, even if it is not Asbestos Waterline, with payment in accordance with CMS 109.05. *** DISCLAIMER - Prebid questions and answers provided are for informational purposes only and are not part of the Bid Documents.

Monday, December 01, 2014 3:11:48 PM Page 17 Ohio Department of Transportation - Prebid Questions Question Submitted: 10/29/2014 2:35:58 PM Please review REF# 172, EBS and the Proposal call this Patching Concrete Bridge Deck 125 SY, while the plans call out Patching Concrete Structure, As Per Plan 125 SF? Which one is correct, we believe it to be the Patching concrete Structure 125 SF. Can ODOT verify and correct this? See forthcoming addendum.The plans are correct and the item will be revised to a SF unit. Question Submitted: 10/29/2014 2:11:47 PM Please check the quantity on reference #150 Full Depth Repair. 78 CY seems like an extremely high quantity for this type of work. See forthcoming addendum.The quantity will be revised to 10 Cubic Yards. Question Submitted: 10/27/2014 4:54:23 PM For REF #101 Field Painting of Damaged Structural Steel as Per Plan, what areas does ODOT anticipate this item to cover? Does this cover scupper removal areas and new/old bearing areas outside of the new abutment diaphragms? Any guidance as to the intended areas would be greatly appreciated. See forthcoming addendum.The item is to repair paint damaged by project work and contractor damage including nicks, scrapes, concrete slurry, welding, etc. Question Submitted: 10/27/2014 2:44:36 PM Plan notes on sheet 9 indicate that asbestos testing has already been complete and no asbestos has been found. If this is true there is no need for the asbestos abatement note on sheet 9 as well as the bid item #22. If ODOT's concern is any unforeseen asbestos there is no way for a contractor to legitimately determine how to price this item knowing no asbestos was found in the original survey. Will ODOT eliminate this bid item and handle any unforeseen asbestos encountered as extra work? This would be fair to all bidders as well as ODOT since this item is to handle an unforeseen situation. The Lump Sum pay item is to account for items which could contain asbestos, but were not surveyed. These items, per the note on sheet 9, include inaccessible areas, concrete, paint, asphalt, debris, and piping. The bid item will not be deleted from the project.

The quantity seems to be in error. But regardless, would the department consider releasing the material to be incorporated into the project? In the Item 254-Pavement Planing, Asphalt Concrete, as Per Plan note on sheet 3, the quantity of grindings to be delivered is incorrect. It should be 4936 Tons (2468 c.y.). The square yard quantity on the general summary is correct. All of the above quantity is still to be delivered to Wintersville Street Department. Question Submitted: 11/19/2014 3:27:44 PM Request to waive PN 420 note from the Project for the following reasons:1.)There are multiple sections of this project that does not meet the designer recommendations for minimum speed limit of 50 MPH and minimum thickness of 3 inches of new pavement. 2.)This Project has multiple intersections which disrupts the normal paving process in order to transition in and out of these areas.3.)Varying number of lanes and lane widths with and without curbs.Historically, other projects similar to this in District 11 have had PN 420 waived for the same above reasons, i.e. Project 06-12, state route 213. The PN 420 will not be removed on this project. *** DISCLAIMER - Prebid questions and answers provided are for informational purposes only and are not part of the Bid Documents.

Question Submitted: 11/21/2014 10:59:50 AM The Construction Noise Restriction noted on Sheet 8/183 conflicts with the requirements to perform many activities during periods or permissible lane closures per the notes on Sheet 11/183. Will there be a variance to the permissible lane closures restrictions or to the City of Cleveland noise ordinance? A noise ordinance waiver may be obtained from the City after project award once details are made known regarding the length of waiver and equipment used, etc. Question Submitted: 11/20/2014 4:48:37 PM On plan sheet 143/183, there are cross-hatched areas at the new abutments that indicate "Area to be excavated prior to Phase 1 Substructure removal". How is this excavation to be paid? It does not appear to be included on the I-77 cross sections on sheet 64/183. Please clarify. The excavation in front of the proposed abutment is included with the roadway plans (sheets 64 and 65), under Item 203, Excavation. The remaining portion is included under the bridge plans as a lump sum bid Item for Unclassified Excavation, As Per Plan. Question Submitted: 11/20/2014 4:35:47 PM The bridge drawings require the use of two "Workzone MSE Walls". The question is this: do the fill quantities as shown on the crosssections from stations 9+02 to 11+14 (plan sheets 68-70) take into account the volume of select granular backfill required for the MSE walls? Should this quantity be deducted from the fill quantities? See plan note on sheet 143 of 183, which specifies the design of the workzone MSE wall. The wall is not designed as this is the Contractor’s responsibility; therefore, the plans do not indicate the amount of select granular backfill since this is dependent on the workzone MSE wall design. The amount of select granular backfill will need to be subtracted out of the fill quantities.

CEI - The Utility Note is correct. The ODOT Contractor will corrdinate the respective work with Dominion, TWC, and CPP. Question Submitted: 11/6/2014 11:03:56 AM Can ODOT please provide existing bridge drawings for bidder's use? information is available on the website ftp://ftp.dot.state.oh.us/pub/Contracts/Attach/CUY-22891/ Project No. 140576 ROS-87326 - -BH-FY 2015 Sale Date - 12/11/2014 Question Submitted: 11/26/2014 9:55:31 AM Can the completion date be extended to 9/30/15, so we can utilize the typically dry and low water conditions of August and September? The completion date is being revised to 10/31/15 in forthcoming Addendum No. 1. Question Submitted: 11/21/2014 12:28:15 PM Can you provide more detailed maps for the locations of the culverts on this project? The small location map on plan sheet 1 is hard to read. Please see the existing plans posted at teh ftp site for more information: ftp://ftp.dot.state.oh.us/pub/Contracts/Attach/D0987326/Reference%20Files/ Project No. 140578 HOC-82832 - SR 56-13.60 Sale Date - 12/11/2014 Question Submitted: 11/6/2014 8:47:00 AM Item 61840101 rumble strips. Is this pattern to be sawed in different locations? Will the dept measure all saw cuts & pay by the Lin Foot ? I have added all cuts in the pattern x 10.5 feet. X 2 & still only get 3000 feet. Please clarify. The location is as stated on sheet 5. Your method of estimating is correct except the Department estimated the lane width to be 12'; the roadway widens near the intersection of SR93. (144 x 12' = 1728' per direction) Project No. 140580 MAD-92877 - -Toland Street Bridge Sale Date - 12/11/2014 Question Submitted: 12/1/2014 9:35:53 AM Can the project completion date be changed to 11-29-15 to match the detour date listed on plan sheet 4?

Monday, December 01, 2014 3:11:48 PM Page 23 Ohio Department of Transportation - Prebid Questions Question Submitted: 11/26/2014 10:02:07 AM Regarding he waterline bore & jack. We understand the city would like the line to not have a casing. If this is the case ductile iron pipe should not be used as this is rarely bored if ever without a casing pipe. Will ODOT and the city allow a directional bore, or will ODOT amend the permit for the job and allow the contractor to open cut the waterline as that is very possible in this area and in fact was just done a few years ago on this same waterline. In summation we ask to either allow a directional bore using different materials, or an open cut using dip cl 52 if a casing pipe is not allowed for the jack and bore as shown on the plans. The City will allow the use of a liner pipe to install the waterline. The contractor is to try minimize the number of joint in the cast iron waterline. No open cut will be allowed. Question Submitted: 11/21/2014 1:15:59 PM On our site review we noticed a drainage pipe on the rear right corner which is shown on sheet 22 on the right of way plans. This pipe is called out as a 15" RCP. It will run right through the new wing wall on the bridge. Should a manhole and new pipe be laid to avoid the bridge? Where would any of this work be paid for? Please address this pipe issue. This will be addressed in a forthcoming addendum. Question Submitted: 11/19/2014 9:49:20 AM Plan sheet 8 shows the detour plan and has notes 1 and 2 including temporary crosswalks as well as temporary sidewalk curb ramps. Can ODOT please clarify that these are incidental to the 614 item as shown in note 4 and correct the bid item to be Maintenance of Traffic As Per Plan? Also will ODOT allow the sidewalk extensions/curb ramps to be left in at the end of the job? All work was accepted to be paid for under Item 614 – Maintaining Traffic and is stated as such in the General Notes and on the Detour Plan. Large portions of the detour signing note are not applicable. The plans have been updated to change Item 614 – Maintaining Traffic to be as per plan, include the applicable portions of the detour signing note under the general note for Item 614 – Maintaining Traffic, As Per Plan, and clarify in the notes that temporary walks and curb ramps need to be removed unless they are installed to the BP-7.1 (7/18/2004) standards. The temporary curb ramps are being installed in tree lawn areas to connect existing sidewalks to the curb, areas which are assumed to be within the R/W at their respective locations. No above ground utilities are known to exist at these locations. OUPS must be called prior to digging. These changes will be included in Addendum 1. Question Submitted: 11/19/2014 9:41:16 AM For the waterline relocation as shown on plan sheet 2 for the bore and jack, will a casing pipe be required? If so what are the specifications for the casing pipe and fill of the casing pipe? Marty Colwell from City of London Public Utilities, responded that casing is not required and would prefer that it is not provided stating his reasoning as it would make future maintenance difficult. Question Submitted: 11/18/2014 9:13:07 PM Are any cross sections available for the excavation/embankment work on the job to check quantities? Cross sections were not developed for this project as they follow a simplified plans format as the approach work is minimal. Question Submitted: 11/18/2014 9:12:24 PM Please add a bid item for 1 dynamic load test, as it is required in the notes for the pile driving. A bid item will be added in Addendum 1. Question Submitted: 11/18/2014 4:44:02 PM For the waterline relocation can any additional information be given? Will the contractor be required to bore and jack the line as shown on sheet 2/22 but not called out in any other notes? Will a directional bore be considered with polyethylene pipe? Contractor must bore and jack the pipe under Oak Run and a minimum class 52 ductile iron pipe is required as the plan note indicates. Question Submitted: 11/18/2014 4:25:23 PM Please add a bid item for seeding and mulching, fertilizer, etc as there will be earth disturbance inside the construction limits for structure excavations and access ramps. Bid items will be added in Addendum 1. *** DISCLAIMER - Prebid questions and answers provided are for informational purposes only and are not part of the Bid Documents.

Monday, December 01, 2014 3:11:48 PM Page 24 Ohio Department of Transportation - Prebid Questions Question Submitted: 11/18/2014 3:59:32 PM There are no utility notes listed in the proposal. the plan and profile show an electric line approximately 7 FT off the off the left edge of bridge deck label to remain. Will this line be able to be relocated, or temporarily shut down for pile driving operations and bridge beam setting? The 7 FT distance will create OSHA violations and the piling is actually closer than that. Agree that aerial electric lines and telephone lines will be in conflict with pile driving and beam setting. The overhead electric lines are the City of London’s power feed for the street lighting. Steve Hume from the City of London has been contacted and stated that the lines can be de-energized for pile driving and beam erection operations. The plans will be updated to reflect this in Addendum 1. AT&T has lines on the same poles, but telephone lines are not subject to OSHA clearances for energized power lines.

Field verify and match control type of existing VAV boxes." What is the make of the existing building automation system that we need to tie in to? The company is Trane. As the District is moving forward on upgrading the HVAC system, it is recommended that Delta Controls are used for the new installation. Question Submitted: 11/19/2014 1:37:46 PM What is the existing fire alarm system and security system for the building? The District has a security and fire alarm system through Northwestern Ohio Security. There are fire sprinklers in the ceiling throughout this area. The new outer man doors must have door contacts for the security alarm, and an electronic latch that is activated by the card reader that is to be on the outside of this door as well, for access control.A motion detector will be needed in the lab area, and video camera on the door to the outside, that is hooked up to our monitoring software.

Question Submitted: 11/24/2014 1:16:39 PM Could the Department provide clarification regarding plan note #4 under Maintenance of Traffic Systems on plan sheet 3 of 9. This plan note states at least two flaggers are required for each closure and the contractor shall furnish additional flaggers as directed by the Engineer. Since the closures required to perform the project work are interstate lane closures why would flaggers be required? Flaggers shall be used for potential closures on Chardon Rd. Question Submitted: 11/21/2014 9:10:11 AM Per plan notes the Engineer can deem no lane closures based on special events that increase traffic volumes or conditions too hazardous which we assume would be weather based on the time of year for this project. Will the Contractor have a workday added for each day that the Engineer does not allow lane closures? The Department will consider and process any time extensions per C&MS 108.06. Question Submitted: 11/21/2014 9:09:17 AM Would the Department consider extending the completion date since there is two holidays with holiday weekends that do not allow lane closures to be implemented per plan notes? Since these holidays are on Thursday is the no lane closure period from noon Wednesday through noon Monday? The completion date will be revised in a forthcoming addendum. Question Submitted: 11/21/2014 9:08:10 AM Could the Department provide the date when the contract will be executed since there is only a little over six weeks from bid date to the completion date of 1/13/15 with major holidays during this period. Typical time period for obtaining a signed contract is between 3 and 5 weeks.

Pay limits shall be per square footage in place and accepted of the footprint area of the timber subdecking, including plywood and timber beams. Overlapping plywood areas, as shown on Section A-A on Sheet 9, shall only be paid as one area and not duplicated. Question Submitted: 11/21/2014 8:05:12 AM Will the district allow a total closure of the express lanes to perform the sub decking work? This would allow the work over express lanes to be completed in one long shift rather than multiple lane closures. Total closure of the express lanes to perform the sub decking work will be allowed per forthcoming addendum.
