About this file
This is a Bid Clarification document issued by Rockford Construction Company for the Northview High School Athletic Stadium Addition & Renovation project located in Grand Rapids, Michigan. The clarification, dated September 9, 2026, addresses five Requests for Information (RFIs) submitted by bidders and subcontractors during the bidding phase. The document provides scope clarifications regarding lighting fixtures beneath bleachers, concrete foundations and flatwork requirements, aluminum facade specifications, auxiliary angle frame bleacher finishes, and tread plank finishing standards. Contact information for local excavation contractors (John W. Potter and Dykema Excavators) and concrete contractors (Choice Concrete Construction, Schepers Concrete Construction, and Prime Construction Co.) is provided to assist bidders in obtaining local pricing for these services.
The RFI responses clarify several key scope elements for Bid Category 13: lighting fixtures for walkways beneath bleachers have been removed from the bleacher contractor's scope and will be included in the overall electrical scope provided by others; all concrete required for foundations and flatwork for bleachers, grandstand, and press box, including 21AA aggregate base materials, falls under Bid Category 13; black vinyl chainlink fence (per sheet LD5.02 details) applies to the elevated walkway and stair areas rather than colored aluminum facade; auxiliary angle frame bleacher risers shall be finished with clear anodized aluminum rather than color-coated aluminum; and tread planks shall remain mill finish despite industry concerns regarding oxidation and staining of uncoated aluminum surfaces. The project manager and assistant project manager from Rockford Construction coordinated these clarifications with design firm Integrated Design Solutions.

Question Question from Morgan Gross Rockford Construction on Wednesday, Sep 2, 2026 at 09:48 AM EDT Tread Planks are called out as Mill Finish. The inherent trait of mill finish aluminum is oxidation and staining. Mill finish indicates uncoated. Section 133510.3.1.C & 133525.3.3.B states that Bleacher Contractor shall be responsible to clean or replace foot planks that become stained or oxidized beyond an acceptable level based on industry standards. Industry standards state that is mill finish aluminum is provided, expect staining and oxidation, because the metal is uncoated. The specification for any mill finish material is recommended to be changed to a minimum clear anodized finish. Coating the mill finish aluminum is the only assurance for acceptable staining and oxidation.
