1 REQUEST FOR CONSTRUCTION BIDS May 23, 2017 Cambridge Greenway Trail / Railroad Bridge Replacement Flood Mitigation Project 1.0 Project Background A former railroad bridge that currently carries the Cambridge Greenway Trail over the Brewster River will be replaced with a refurbished historic bridge and elevated boardwalk over a restored floodplain. The goal of the project is to reduce flooding in and a recent study has identified that the current undersized bridge is increasing flooding to Route 15 and nearby residential and commercial properties in the Village. Construction plans accompany this Request for Construction Bids (Attachment A). Project construction is anticipated between July 1 and December 15, Disturbance must be minimized and contained with sediment and erosion controls that will be applied and maintained throughout the duration of the project. Borings (see Attachment A) and a geotechnical study (Attachment B) have been completed as part of the design. The Town of Cambridge, Vermont, (the Town) in partnership with the Lamoille County Planning Commission (LCPC), is currently seeking competitive bids to replace the bridge and restore the floodplain. Companies that are women owned, minority owned, Section 3, and small businesses are encouraged to submit bids. A second separate but nearby flood mitigation project is also expected to be constructed during summer 2017 to replace two culverts that pass under Vermont Route 15 in Jeffersonville. The bid for the culvert replacement project is expected to be released in the next month by the Village of Jeffersonville and LCPC. Contractors are encouraged to bid on both projects for efficiency and economy. The lowest and responsible bidder may be awarded the contract for both the bridge and culvert project, or one of the projects. This is solely a disclosure statement due to the close proximity, similar timing, and flood mitigation objectives of the two projects. 2.0 General Scope of Work Work tasks will generally involve installation and maintenance of erosion and sediment controls; excavation of earth fill and hauling offsite; removing the existing railroad bridge; demolition of concrete; handling, transport, rehabilitation, and re erection of a historic bridge; installation of micropiles; installation of reinforced concrete piers and abutments; installation of an elevated wooden walkway on steel beams; installation of dry stacked rock walls; installation of riprap; installation of fencing; and site restoration (see Attachment A).

2 Allowable work hours will be Monday thru Friday from 6 am to 7 pm. With 48 hour notice to the Town and Project Engineer, additional work hours may be approved. All disturbed areas shall be returned to pre construction conditions, including repairs of the road surface, seeding and mulching all disturbed areas. Disturbance shall be minimized during construction. Live willow stakes will be furnished and planted by others. Live stakes are shown on the Site Plan and in the detail with the riprap (see Attachment A), but are not be included in this bid or contract. 3.0 Owner s Project Representation Engineering oversight of the project will be conducted by LCPC s appointed Project Engineer in combination with a VTrans Inspector. The Contractor will be obligated to comply with directives from the Project Engineer and VTrans Inspector to ensure that the Contractor meets all contract provisions and design specifications while complying with permit requirements. The VTrans Inspector will be approving all work related to the highway, in particular the toe of slope condition along Vermont Route Construction Access Construction access will be made primarily from the Vermont Route 15 Park and Ride owned by VTrans. A VTrans State Highway Access and Work Permit has been received for this project covering access to the construction site, staging of equipment and materials, and work within the ROW (Attachment C). Removal of vegetation at each access location shall be minimized. If the Contractor wishes to leave the Town or VTrans right of way or Town owned land, permission is required from landowners to cross their property. A secondary construction access has been proposed across private land at 5195 Vermont Route 15 on the western river bank. Use of this access will need to be arranged by the Contractor and will require prior approval with the landowner. Closure of Vermont Route 15 is not anticipated as part of this project, yet traffic flaggers will be needed for trucks entering and leaving the state highway. All abutters will have been notified about the project before construction by LCPC. 5.0 Sequence of Work A possible sequence of work is provided in the construction plans (see Attachment A). The final sequence of work will ultimately be determined by the Contractor and submitted to the Project Engineer for review and approval prior to construction. The Contractor shall present their project schedule and list of subcontractors at the preconstruction conference. The Project Engineer and Town will review and comment within 5 work days. 6.0 Specifications Technical specifications are included in the details and notes on the construction plans (Attachment A). The Contractor shall refer to the VTrans 2011 Standard Specifications for Construction. Project special provisions have been provided (Attachment D). A formal technical specification package does not exist for this project. The Contractor shall adhere to the Terms and Conditions in the Contract with the Town.

3 7.0 Sediment and Erosion Control A possible sediment and erosion control plan is provided in the construction plans (see Attachment A). The final sediment and erosion control plan will ultimately be determined by the Contractor and submitted to the Project Engineer for review and approval prior to construction. The Contractor shall present their sediment and erosion control plan at the preconstruction conference. The Project Engineer will review and comment within 5 work days. Limits of area of disturbed earth (2 acres) and length of time of unstabilized disturbance (7 days) have been established to minimize impact to the river. Silt fencing will be required around any stockpiled materials to contain sediment migration during construction. Runoff from the excavation area shall be contained with silt fence between the excavation and the river bank. Water control is needed during work on the banks and at the river edge to prevent siltation of the river. Separation of river flow from the active work area at the river banks is required, and recommended by using temporary isolation berms constructed from on site river cobble and gravel. 8.0 Construction Notes Construction notes are contained in the construction plans (see Attachment A). 9.0 Construction Schedule Construction is planned for between July 1 and December 15, All instream work in the river or on river banks (below the ordinary high water (OHW) line) must be completed between July 1 and October 1.

Site recovery progress will be inspected with the Contractor approximately one month following construction to ensure that the site remains stable and to determine if additional site recovery work is needed. VTrans and the Project Engineer will be required to sign off on the final site conditions Regulatory Requirements Federal, state, and local permitting is under way for this project and conditions of each permit must be followed during construction. The Contractor must review permits in full to understand all regulatory requirements prior to construction. All permits must be posted at the project site prior to the start of construction.
