Freestanding Concrete Mockups

This contract awards the fabrication of two freestanding concrete mock‑ups that replicate the natural stone spandrel walls of the North Main Street Bridge over the Chagrin River in Chagrin Falls, Ohio. The mock‑ups are each approximately 8 ft long, 4 ft tall, and 12 in thick, and they must be constructed using vertical form‑liner systems, stained to match stone, and sealed per the specification. The county’s Purchase Analyst, Wendy Houston‑Johnson, acted as the primary contact for the award. • Scope: design, form‑liner installation, concrete pour, curing, color‑stain application, and clear‑sealer finish for two architectural mock‑ups. • Technical requirements: 28‑day cure before staining, 10 ft/hr pour rate, ≤¼ in liner compression, dry weather 50‑90 °F for stain/sealer, and performance‑tested stain durability. • Deliverables: completed mock‑ups, shop drawings, product data sheets, and any required samples for engineer approval.
