3 Plan sheets: Yes, Revised Sheets: 3, 11, 12, 41, 43, 52, 53, 54, 55, 56, 159, 160, 161, and 173 Answers to Prebid Questions: yes 03/14/ :56 AM Question: Can you provide more detail for the sewer trench detail shown on sheet 173, Is the 5 to the center line of pipe or side of the trench excavation? The reason I m asking is it appears to be a large quantity of the 54 pipe that the pipe trench would fall within the 5 of the edge of pavement. Answer: See sheet /15/ :40 AM Question: On Sheet 55 Water Work Subsummary of the plans under the reference to Sheet 181, Ref. No. WL2. It refers to 11 LF of 12 Water Main at Sta , LT. Could this size and length be confirmed? The 11 under WL2 on sheet 181 should be 1 service line instead of 12 waterline. 03/16/ :57 AM Question: Ref addendum 4 changed the quantity from 12 each to 13 each. Subsummary sheets 55 and 56 total up to only 10 each. Which is the correct quantity? Please review. The correct quantity is 13 Ea. See Sheets 55 & 56 03/14/ :10 PM Question: Ref. 148 and 149- plan quantities for both sanitary items appear to be incorrectly understated. Please review all locations and notes shown on plan sheets and revise the quantities accordingly. See revised sheet /16/ :39 PM Question: The proposed Sanitary Sewers will be connected to live sewers. If rigid pipe is utilized, will the required leakage test and video be performed before the sewers are connected. If flexible pipe is utilized will the contractor be held to the 30 day wait period for the deflection test.also, underitem 603 Conduit, As Per Plan A for Storm Sewers, allows the use of CMP Pipe, is that correct.cmp Pipe is classified as a flexible pipe, but will not pass the required deflection test. Will the deflection test be waived for CMP PIPE. There are going to be situations were testing cannot be completed due to physical restraints such as the case with some service laterals. In these cases, the testing may be waived as directed by the engineer. The deflection testing will not be waived. 03/16/ :56 PM Question: The sanitary sewers that are "live" taps (Ref. Nos ) cannot be deflection tested or leakage tested. There will not be an access point at both ends to perform the work. Ref. No. 145 cannot be pressure tested since the joint cannot be sealed. Will there be an addendum to correct the plan notes?

4 There are going to be situations were testing cannot be completed due to physical restraints such as the case with some service laterals. In these cases, the testing may be waived as directed by the engineer. 03/16/ :30 AM Question: Does as per plan A & B sanitary & storm conduit to be using trench detail on plan sheet 173? If so, does premium backfill go up to existing pavement or per ODOT requirements for 603 conduit. Premium backfill goes to existing pavement. 03/15/ :42 AM Question: Addendum 4 changed the phasing to install the 12 waterline along the west side of SR 25 prior to Phase One. The installation of the waterline will result in removal of the curb, pavement and catch basin(s) from Sta ~ along the west side of SR 25. Prior to moving traffic to Phase One will the curb, pavement, drainage etc need to be restored temporarily? Yes if the contractor elects to do all the waterline installation at once. If the contractor chooses, he can construct the proposed waterline up to approximately STA so that the existing 6 waterline along the east side can be abandoned. The remainder of the waterline can be constructed at a later stage. 03/16/ :37 AM Question: Please review the note and quantity for Item 409 longitudinal joint sealed on sheet 10. Due to the depth of the cold joints (7 302 depth on SR-25) and the staged construction the quantity seems low. Quantity is correct 03/16/ :31 AM Question: Where can the water in the existing 78 inch combination sewer (REF. NO. 145) be pumped to? Are there any restrictions on where this water can be pumped to while installing the 63 inch by 98 inch pipe? What are the flow rates in the existing 78 inch pipe? The contractor can pump around the work area back into the existing downstream 78 combined sewer. They can also pump the water into the the 42 or 48 sanitary sewer as long as they do not exceed the capacity of the sanitary sewer. Existing flow rates are unknown. BG Sewer Division believes there to be adequate capacity in the 42 or 48 sanitary sewer to allow the bypass pumping during dry weather conditions. Question: 2/16/11 4:59 pm From Poe Rd. to Sta on SR 25 the elevation of proposed widening on the east side will be higher than the adjacent existing pavement. How will traffic be maintained and how will drainage be maintained if this condition goes over the winter? Response: We do not believe this will be an issue, the contractor will need to stage their work so that drainage is maintained. There may be locations where we will need to address this but we believe it can be worked around and we won t know the exact problems to contend with until we know the contractors schedule. 03/17/ :14 AM

5 Question: The proposed 12 waterline from Sta to Sta , RT and connection detail A (sheet 178) have several issues that need clarification: a. The 12 waterline goes under the existing 21 and 78 combination sewer. The proposed invert of the 12 waterline where it deflects under the existing 78 is about (sheet 178). The top of rock elevation at this location is (sheet 61). The invert elevation of the existing 78 is about from the manhole information given on sheet 61. This will require a minimum of 2.0 of rock excavation underneath the existing 21 and 78 combination sewers. Furthermore, the distance between the existing 78 combination sewer and the location of the 24 PCCP waterline tap (Connection Detail A, sheet 178) is not sufficient to make a live tap. Therefore, this will require removal of sections of the 21 and 78 combination sewers, bypass pumping of the combination sewers during rock excavation and 12 waterline installation and replacement of the 21 and 78 combination sewers. How will the removal and replacement of the 21 and 78 combination sewer and by-pass pumping be paid for? b. The MOT plans (Phase 1, sheet 23) make no provisions for closing traffic to install the 12 waterline and connection detail A (sheet 178). With the extensive work required as outlined above, the entire intersection will require closure. How will traffic be detoured and who is responsible for detour signing? What will the detour be? There is sufficient room to perform the live tap without removing the existing combined sewers and therefore the intersection will not need to closed. Worst case, we will tap from the back side of the pipe. 03/15/ :43 AM Question: Sheets 175 and 183A refer to Waterline Thrust Blocks. The note on Sheet 175 states: PROVIDE THRUST BLOCKS AS CALLED FOR IN THE PLANS AND AS DEFINED IN THE DETAIL SHEETS The note on Sheet 175 states that Mechanical Joint Restraints are to be used. Are Mechanical Joint Restraints to be used in lieu of Thrust Blocks? Mechanical restraints shall be used where possible. The thrust blocking details are provided because there may be situations when mechanical restraints cannot be used and thrust blocking will then be required. Question submitted 03/15/ :42:11 AM: Clarification of earlier answer from Addenda 5. Question Attached: Addendum 4 changed the phasing to install the 12 waterline along the west side of SR 25 prior to Phase One. The installation of the waterline will result in removal of the curb, pavement and catch basin(s) from Sta ~ along the west side of SR 25. Prior to moving traffic to Phase One will the curb, pavement, drainage etc need to be restored temporarily? Answer: Yes if the contractor elects to do all the waterline installation at once. The Temporary Curb, Catchbasins and any other additional pipes shall be included in the Item 615 Roads for Maintaining Traffic to maintaining positive drainiage. Additional Pavement have been added to Pavement for Maintaining Traffic, Class B. If the contractor chooses, he can construct the proposed waterline up to approximately STA so that the existing 6 waterline along the east side can be abandoned. The remainder of the waterline can be constructed at a later stage.

6 NESHAP ASBESTOS SURVEY REPORT (PRE-DEMOLITION) LOCATION: HOME & GARAGE 962 N. MAIN STREET BOWLING GREEN, OH CONDUCTED FOR: CITY OF BOWLING GREEN, OH CONDUCTED: MARCH 2, 2011 CONDUCTED BY: BRUMBAUGH-HERRICK, INC N. WOODBRIDGE RD. MONCLOVA, OH FAX BHI Brumbaugh-Herrick, Inc.

7 NESHAP ASBESTOS INSPECTION REPORT HOME & GARAGE AT 962 N. MAIN STREET, BOWLING GREEN, OH CITY OF BOWLING GREEN Date Performed: March 2, 2011 By: Brett L. Brumbaugh Ohio Department of Health Asbestos Hazard Evaluation Specialist License #ES3488 Asbestos Hazard Abatement Project Designer #PD60095 INSPECTION SUMMARY On March 2, 2011, Mr. Brett Brumbaugh performed an inspection and sampling to comply with the US Environmental Protection Agency (EPA) regulation National Emission Standards for Hazardous Air Pollutants (NESHAP). The purpose of this inspection was identify and quantify the potential asbestos containing materials located in the home and garage located at 962 N. Main Street in Bowling Green, OH prior to the planned demolition of the structures. Bulk sampling of suspected ACM was based upon the appearance, texture, and location of the material. All bulk samples were analyzed utilizing current EPA methods for PLM (Polarized Light Microscopy) by EMSL laboratory in Ann Arbor, MI. The laboratory is accredited by the NIST, NVLAP program (National Institute of Standards and Technology, National Voluntary Laboratory Accreditation Program) and also an American Industrial Hygiene Association (AIHA) accredited laboratory. ASBESTOS CONTAINING MATERIALS SUMMARY: There were no asbestos containing materials found as a result of the inspection in either the home or garage. CONCLUSIONS/RECOMMENDATIONS There were no asbestos containing materials found as a result of the inspection in either the home or garage, therefore the structures can be demolished as planned. Please note that a Notification of Intent to Renovate/Demolish is required to be submitted to the Ohio EPA by the demolition contractor in accordance with the NESHAP regulation at least 10 working days prior to the beginning of any demolition project.

8 NESHAP ASBESTOS INSPECTION REPORT HOME & GARAGE AT 962 N. MAIN STREET, BOWLING GREEN, OH CITY OF BOWLING GREEN ASBESTOS INSPECTION SAMPLING PROTOCOL & GLOSSARY SAMPLING PROTOCOL The bulk samples were collected from locations that were selected to be representative of the building materials. Sampling was accomplished using the simplified sampling scheme referenced in the AHERA regulations and found in the Pink Book. Locations of individual samples are referenced on this report. The samples were either collected with a coring tool designed for asbestos sampling or placed into a plastic bag for laboratory analysis. The samples were analyzed via polarized light microscopy with dispersion staining, using the Interim method for the Determination of Asbestos in Bulk Insulation Samples found in Appendix A to Subpart F in 40 CFR Part 763. The regulations require specific numbers of samples be obtained per homogeneous area. For example when sampling for joint compound or asbestos in hard plaster (sprayed-on or troweled-on surfacing materials) samples are to be taken based on the following increments: 0 to 1000 square feet of material, 3 samples are necessary. From 1001 to 5000 square feet, 5 samples are necessary, over 5000 square feet 7 samples are required. If during analysis any samples are found to contain asbestos, the entire homogeneous area is delineated as asbestos containing material. In the case of pipe insulation or other types of manufactured materials, the regulations require only enough samples to ascertain whether asbestos is present. In this case, the minimum amount of samples to collect and analyze is usually three. The sampling performed in this inspection followed these sampling guidelines. ASBESTOS GLOSSARY OF TERMS Friable asbestos material: means any material containing more than 1 percent asbestos as determined using the method specified in appendix E, subpart E, 40 CFR part 763 section 1, Polarized Light Microscopy, that, when dry, can be crumbled, pulverized, or reduced to powder by hand pressure. Category I Non-friable Asbestos Containing Material (ACM) means asbestos containing packings, gaskets, resilient floor coverings, and asphalt roofing products containing more that 1 percent asbestos as determined using the method specified in appendix E, subpart E, 40 CFR part 763, Section 1, Polarized Light Microscopy. Category II Non-friable ACM means any material, excluding Category I non-friable ACM, containing more than 1 percent asbestos as determined using the method specified in appendix E, subpart E, 40 CFR part 763, section 1, Polarized Light Microscopy that when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure. Regulated Asbestos Containing Material (RACM): means (a) Friable asbestos material, (b) Category I non-friable ACM that has become friable, (c) category I non-friable ACM that will be or has been subjected to sanding, grinding, cutting, or abrading, or (d) Category II non-friable ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder by the forces expected to act on the material expected in the course of demolition or renovation operations regulated by this subpart.
