About this file
This Addendum No. 2, dated May 29, 2024, modifies the contract documents for the Tahquamenon Falls State Park Upper Falls Brink Overlook project managed by Michigan Department of Technology, Management and Budget (DTMB) and the project engineer OHM Advisors. The project scope requires material, equipment, labor, and services for installation of a universal access path and brink overlook viewing platform at the Upper Falls, including concrete and helical foundations, new boardwalk and viewing platforms, clearing activities, HMA removal, salvaging and installing furnishings, and removal of existing stairways and platform structures. The mandatory pre-bid conference was held on July 16, 2023, at the project site. Bids are due Wednesday, June 12, 2024, at 2:00 p.m., submitted electronically through the SIGMA website. The contract time runs from a Notice-to-Proceed approximately mid-September 2024 through substantial completion by July 31, 2025. The addendum approves Fibergrate Composite Structures as an additional manufacturer for fiberglass reinforced gratings and designates Helical Pier Distributions LLC as an approved manufacturer of steel helical piers alongside AB Chance Company and Aluma-Form/Dixie. Updated specifications detail steel helical shaft requirements including Type SS and N80 materials with minimum torsional strength ratings of 5,500 ft-lb and 70 ksi yield strength.
The project imposes liquidated damages of $1,000 per calendar day for work not substantially completed by the deadline. Prevailing wage rates apply to all work performed on the project, as detailed in the contract documents. Contractors must obtain all permits required by LARA and other agencies at their own cost and are solely responsible for scheduling inspections and maintaining jobsite security. A jobsite superintendent who is an employee of the contractor must be present 100 percent of the time whenever work occurs. Bid security in the amount of 5 percent of the base bid price is required. The base bid includes a $100,000 allowance, with separate schedules for alternatives (existing staircase removal) and change order prices (concrete foundations and helical piles). Contractors must submit a certification of Michigan-based business form for projects exceeding $100,000, and qualified disabled veteran business representation forms if applicable. Construction activity is strictly limited to designated work zones with penalties ranging from $500 for the first incident to $5,000 for subsequent incidents of unauthorized construction activity outside established limits.
