Item Steel Piling HP 12x63 will be separated from the lump sum bid and bid as a unit price item per linear foot. Based on soil boring log SB-1, the Bidder shall bid assuming that each of the four (4) piles will be driven twenty five (25) feet for a total of one hundred (100) feet of steel piling.

2 Seymour Road Replacement Bridge Addendum #1 April 27, 2015 conduct material testing work, as needed. All material testing results shall be provided directly to the project engineer and Town. All material testing costs shall be included under item 631-Material Testing. The Project Engineer, Mr. Stephen Diglio, P.E. and Town of Westford Road Foreman, Mr. Brent Meacham, will conduct periodic site inspections and shall be notified in advance of project milestones. Project milestones will be identified during a preconstruction meeting with the successful bidder. There will be no Bituminous Concrete Pavement included as part of this project. The bid form has been revised accordingly. No Replacement Bridge Alternative Designs will be considered, and Bidders shall submit bids only for the replacement bridge design presented in the Contract Drawings. The main funding source for this project, FEMA, has only provided specific approval for Replacement Bridge scope of work for a precast concrete beam bridge and concrete deck with a 42 span and 8 rise, as shown in the Contract Drawings. Based on recent correspondence with personnel from the Vermont Department of Public Safety, any deviation from the approved FEMA scope of work could jeopardize funding for the entire project. In addition, to obtain approval for an alternative replacement bridge will require a change of scope approval by FEMA, which would delay the project by a year. A delay of this magnitude is not acceptable to the Town. Alternatives for the Temporary Road Brook crossing structure will be considered since the road is temporary in nature, and FEMA has yet to provide approval for any specific scope of work for the temporary road. Bidders shall provide a temporary brook crossing structure that has a minimum hydraulic opening equivalent to three (3) six (6)-foot diameter culverts, and maintains the same road alignment as the temporary access road provided in the Contract Drawings. Sheet SP.1 of the Contract Drawings has been revised accordingly, and attached to this memo. If a Bidder chooses to utilize the existing boiler plate culverts that are currently onsite, he/she shall determine whether the existing culverts are adequate to handle his/her equipment. A turf dragging is an acceptable finish method for the replacement bridge deck. The Mud Mats are a required per the abutment structural design. The contributing water for the Beaver Brook drains an area of approximately 8.4 square miles of hilly to mountainous terrain. The land Page 2 of 3
