About this file
This is a civil engineering bid set document for the Forest Hills Nature Center New Building project located at 1297 N Rich Road, Alma, Michigan 48801, in Seville Township, Gratiot County. The document contains detailed technical drawings and specifications for wastewater and drainage infrastructure systems required for the new nature center facility. Key components specified include a duplex sump pump station with dual pumps featuring redundant high water and low water alarms, a lift station with specific operational sequencing, a septic tank system designed for H-25 loading with 0.0 to 3.0 feet of earth cover per AASHTO 17th edition and ASTM specifications, and a drain field system measuring 40 feet in width. The document details all piping specifications including Schedule 80 PVC pipe with tracer wire and warning tape for force mains, perforated HDPE N12 pipe for cooling tower drains, and Schedule 40 PVC piping for various lateral connections. Concrete specifications require 5000 PSI at 28 days with reinforcement per ASTM A-615 and A-496 standards.
The bid set provides comprehensive technical specifications and design criteria based on Mid-Michigan Health Department guidelines for septic and drainage systems. All drawings are presented at various scales with detailed elevation references, dimensions, and materials callouts necessary for contractor bidding and construction. The contractor is responsible for providing and installing all controls on the building to meet the specified sequence of operations for the pump station. No pricing information, bid deadlines, award dates, or contract terms are included in this civil engineering document.
