3 GENERAL 1. ALL BIDDERS SHALL USE THE ATTACHED REVISED ITEMIZED UNIT PRICE BID FORMS (2 PP.; pages 4 of 8 and 5 of 8). If these attached bid forms are not used, the bid will be considered non-responsive. 2. Bid Item 11, Trench Sheeting Left In Place. The Bid Quantity shall be revised from 1000 SF to 200 SF. 3. Bid Item 19, Additional Allowance. The Unit Price Bid shall be revised from $50, to $35, PRE-BID QUESTIONS 1. Question: What is the flow rate in existing sanitary sewer? Please provide us sanitary sewer flow rate in MGD in order to figure out sanitary sewer By Pass system. Answer: The existing pump station does not have a flow meter. The only existing flow information we have available is that the existing submersible pumps are designed for 350 gpm at 72 TDH. Also, it is known that rainfall contributes significantly to the flow rate. 2. Question: For connection with existing 8 DIP force main and in order to perform sanitary sewer by pass, we are considering to excavate and install wye and plug valve 10 west of proposed 45 degree elbows on existing force main. Is this method acceptable? Answer: The Means and Methods of accomplishing this bypass are entirely the responsibility of the Contractor. 3. Question: We understand existing pump station is 25 deep below grade. Is there any existing shoring system left in ground around existing pump station? Answer: It is unknown if there is any existing shoring system left in the ground. However, previous maintenance-type excavation on the site has not encountered any existing shoring. 4. Question: There are total 32 new trees to be planted per bid items 18A and 18B (Pine and Deciduous trees); considering the small site area and not knowing planting layout, number of new trees seem to be excessive. Answer: The number of trees was requested by the City Arborist and shall remain at 32. ADDENDUM NUMBER 1, April 25, 2018, Page 2 of 7

4 5. Question: Bid item 10: Additional excavation including premium backfill shows 500 CY. Is this quantity right? Or is it a misprint? Could it be 50 CY instead of 500 CY? What area of site would need undercutting for this much quantity? In our opinion, existing concrete road replacement would not take more than 50 CY of undercutting. Answer: The Bid Quantity shall be revised from 500 CY to 50 CY. 6. Question: It is our opinion that if some of quantities of bid items are not lowered, published engineers estimate would not be enough even considering 10% above engineer s estimate. Answer: No comment. 7. Question: The two soil borings from Geotechnical report does not show rock, project specification for excavation item calls out to include rock excavation; in case if we encounter rock during excavation, will rock excavation work be considered as an extra work? Answer: Yes, rock excavation, if encountered, would be considered extra work. 8. Question: Does shoring system design for new construction require P.E. stamp? Answer: All design calculations shall be signed and stamped by an Ohio Registered Professional Engineer. 9. Question: Any permit required from Cuyahoga County? Answer: No permits are required from Cuyahoga County. 10. Question: Is CCDPW supplying antenna for this project? Answer: The Contractor shall supply and install the new mast and the CCDPW will supply the antenna. The Contractor shall properly install the antenna onto the mast, including, but not limited to, all mounting, wiring, etc. ADDENDUM NUMBER 1, April 25, 2018, Page 3 of 7

5 11. Question: Drawing S-3 calls for the generator fence to be removable. The vinyl fence specified in section DS-46 is not a removable system. Also, we do not know of any removable vinyl fence systems. Please advise. Answer: The intent of the removable portion of the fence is to provide access for a fork lift to remove the generator in the event it needs to be removed for repair. We have successfully provided for such a removable fence on other projects with the following method. On the long (18 ) side of the enclosure, the intermediate fence posts (not including the corner posts) would be made removable by providing a minimum three (3) foot depth of concrete encasement, with a minimum of one (1) foot thickness all around the base of the fence post. The hole for the base of the post in the concrete encasement shall be a formed hole such that the post can slide into the concrete encasement and be removed if necessary. 12. Question: Bid Item No. 17 Erosion Control: Per ODOT, erosion control item carries fixed dollar amount in the bid form. The bid form of this project shows Erosion Control as Lump Sum. If this item is paid Lump Sum, please provide description of what works to be included under Erosion. Answer: In addition to the requirements of DS-54, Erosion Control and Site Maintenance, the following items and quantities are assumed for the Contractor s Bidding purposes: ODOT Item 832 Construction Seeding and Mulching ODOT Item 832 Inlet Protection ODOT Item 832 Perimeter Filter Fabric Fence ODOT Item 832 Sediment Removal ODOT Item 832 Construction Entrance 200 SY 50 LF 700 LF 15 CY 20 CY 13.

6 14. Question: DS-4 Scope of Work Item H indicates placing full depth LSM around the proposed manhole and wet well and indicates the remaining of the project to be backfilled with premium granular backfill. Does DS-4 supersede DS-25? Answer: DS-25 contains the general backfilling specification; applicable as directed by the Engineer. DS-4, H, specifically addresses the requirements for the proposed Wet Well and the proposed Manhole, and also discusses backfill for the remainder of the Project. DS-4 and DS-25 are intended to be complementary; any questions shall be decided by the Engineer. The decision by the Engineer shall be final. 15.
