DIVISION 1 SHORT FORM GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: This project will replace a boardwalk that is structurally failing and creating safety hazards to visitors. Deck boards are rotting causing an unsafe surface for runners and bikers.

The support posts are rotting causing the entire boardwalk structure to shift and become uneven with dips and swales. The existing boardwalk is 10-feet wide and approximately 1670 linear feet in length with transitions to compacted aggregate trail at each end of the boardwalk. The boardwalk is constructed of 2x dimensional lumber and 10-inch diameter treated round wood piers direct buried to a depth of 14-feet. Height of boardwalk above grade varies but is predominantly 24-inches or less.

1.2 Work Covered by the Contract Documents:

A. Project Location: Ohio & Erie Canal Towpath Trail, approximately 1 mile south of Boston Mill Visitor Center and Parking Lot: 6947 Riverview Rd, Peninsula, OH 44264

B. Work consists of: Sequential removal and replacement of boardwalk elements including full decking and framing removal with partial foundation removal to 2-ft below grade. Project includes partial relocation of boardwalk away from the Cuyahoga River. Proposed work includes installing helical piles with timber decking and framing construction, including a bid alternate to use 3x treated S1S rough cut decking lumber in lieu of 2x treated lumber. Work is occurring in an area of cultural and natural resource significance including a Cultural Landscape, high quality wetland, and floodplain. Vehicles and equipment are prohibited on grade in the protected areas around the boardwalk. Trail rehabilitation and natural landscape restoration are required at both ends of the boardwalk. Allowable equipment and material staging areas are denoted in the construction drawings. Boardwalk is in an area of high visitation, and a limited closure of the boardwalk is expected.

C. All work will be performed under a single contract.

D. Period of performance: Work shall be completed within 180 calendar days of the start date provided on the Notice to Proceed.

a. Clarification: The Notice to Proceed will be issued with a period of performance that is all inclusive of supply lead times, material deliveries, decommissioning, installation, anticipated average weather days for location, final commissioning, and acceptance of completed work. The contractor will be expected to provide a project schedule with adequate critical path details to ensure all work is completed within the stated calendar days from issuance of the Notice to Proceed. If weather impacts project beyond typical average weather patterns, contractor shall provide documentation in request for additional days.
