2 PAGE 2 DATE February 1, 2018 ITB - 18B012 Prince William Street Widening Improvement Addendum No. 3 Invitation to Bid No. 18B012 Prince William Street Widening Improvement Question and Answer (Q&A) Bulletin Board for Addendum No. 3 (This document will be updated periodically to share all relevant questions and answers. Any Q&A resulting in an Addendum will be posted on the City s purchasing web site and in eva) Question 31: There is no bid item for 18 Waterline Bends. They do not make 33 RCP any more, what size do you what us to bid? Answer 31: Add a line item for 18 Waterline Bends. Bid 36 RCP instead. Question 32: On Water Line K the contractor is required to install an 8 Cut in Valve. Based on the Proximity to the replacement work I believ-e the City has missed the Temporary Line Anchor 8 requirement and associated line item so the cut in valve can be restrained. Answer 32: Line item for the Temporary Line Anchor (8 ) needs to be added on the Schedule of Values. In addition, one Temporary Line Anchor (12 ) and one 12 Cut-in Valve need to be added as well. Question 33: Line It No 52 Requires three 6 Cut in Valves. The Line item 72 Temporary Line Anchor 6 only requires 2. It appears the quantity is deficient for Line Item No 72 as all the Cut in Valves will need to be restrained. Answer 33: The quantities shown are correct. Question 34: For Line Item No Temporary Line Anchors, After Water Main work is completed is the City expecting the Contractor to remove these Line Anchors or will they be left in Place. Answer 34: Temporary line anchors need to be removed as new water mains are installed. Question 35: For Line Item No Cut in Valve Long Solid Sleeve, Please Verify whether the Valve being installed is required to be a Butterfly Valve or Gate Valve. Answer 35: The valve is a butterfly valve. Question 36: For the items of work that fall outside the replacement profile of the road (Ex. Cut in Tees, Line Anchors ect.) is the patching work going to be paid at unit prices per the contract line items? Answer 36: Yes, unit prices per the contract line items will be used.

3 PAGE 3 DATE February 1, 2018 ITB - 18B012 Prince William Street Widening Improvement Addendum No. 3 Question 37: Line Item No 134 NS Modify Existing Drop Inlet has a pay quantity of 2. Per Plan Sheet 2K(1) there are three inlets to be modified (Ex. D6, Ex. 2940, Ex. 2433). Please adjust the pay item in the next addendum. Answer 37: Pay item 134 NS Modify Existing Drop Inlet shall have a quantity of 3. Question 38: The Contractor is to extend the Pipe from 4-19 to If the existing field conditions are found to require a Concrete Collar to join the pipes, how is the contractor to be compensated for that work? Answer 38: The cost should be included in the line item for the pipes. Question 39: RE: Plan Sheet 4 (0) and 5 (0), Can you provide a Bid Item, details and description for the Decorative Fence referred to on these plan sheets. Answer 39: Part Physical Features in Section Existing Site Conditions of the specifications states When it is necessary to remove mail boxes, fences, stone walls, retaining walls, shrubs, or any other physical features of the project site including property pins, the Contractor shall carefully remove, store, maintain, and reset prior to the completion of the Contract. Property pins shall be replaced by a Registered Surveyor hired by Contractor. The cost of such removal, storage, maintenance, and restoration shall be considered incidental to the project and no distinct payment shall be made. Any existing decorative fences shall be replaced in kind. Question 40: What is the City s intent with regards to installing new sanitary sewer laterals on an existing main? Does the existing lateral have to be removed? Is the new lateral to be installed at the same elevation as the existing one? Answer 40: The new laterals are intended to be installed at the same elevation. However, they can be adjusted, if needed, as long as they meet the minimum slope requirements. Question 41: Answer #13 from Addendum #1 remains unclear. If all excavation is unclassified and the rock clause is being removed, then what are rock excavation units as referred to in the Answer? If rock is to be included in our lump sum Earthwork, then why would the City have to authorize rock excavation? Answer 41: The city has to authorize rock excavation in order to approve the method of removal, schedule the work, and to notify residents if necessary. Question 42: Addendum #2 states that all existing waterline shall be removed within the limits of the work. Then what is the purpose of Item 69 on the Bid Form flowable backfill (abandon existing waterline)?

4 PAGE 4 DATE February 1, 2018 ITB - 18B012 Prince William Street Widening Improvement Addendum No. 3 Answer 42: Item 29 on the Bid Form, Flowable backfill shall be deleted. Question 43: Addendum #2 states that underground utility work on Prince William Street shall begin at the Wellington end first. This directly contradicts all phasing depicted in the waterline section of the plans. The drawings clearly show the waterline work to begin at the Grant Avenue end. Please clarify. Answer 43: The waterline construction sequence on Sheet 12 of the plans and any references to construction phasing on sheets 12(1)-12(8) shall be considered for information only. The phasing shall follow that described in Addendum 2. Question 44: What is the Contractor s responsibility concerning existing driveways all along Prince William Street? The pre-bid presentation has a sheet for driveways with alternative designs. Answer 44: The contractor shall bid the project as designed, some of the driveway designs show work outside of temporary construction easements. The contractor shall follow section 1.13 Work Outside Temporary Construction Easements in the General Requirements section of the specifications for these driveways. Question 45: Is a temporary asphalt patch required for utility installations in areas of the road that are going to be fully reconstructed with new pavement? In other words, if a utility is installed in the roadway, is a 21-B gravel patch acceptable or is an asphalt patch required for all utilities installed beneath existing pavement? Answer 45: An asphalt patch is required when that section of utility work is completed. Question 46: Are there any Specifications for the 300 LF of chain link fence called out on the Bid Form? Answer 46: The line item for chain link fence is to replace existing chain link fence. The replacement item should match existing conditions. Question 47: The attached page from the pre-bid presentation has a list of driveways with alternative designs. Please clarify what the alternative designs are for these addresses. Answer 47: See answer 44. Question 48: Sheet 2(0) has a note saying that All concrete pipe to be placed to be placed within the dedicated right-of-way shall conform to ASTM Specification C76-65T class IV. Please confirm that this is not the case and that storm sewer profiles and drainage descriptions will govern with regards to class of RCP pipe. Answer 48: All storm sewer pipes shall be Class IV.
