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 in Alma, Michigan 48801, within Seville Township, Gratiot County. The document contains detailed technical specifications and construction drawings for the facility's mechanical and civil infrastructure systems. Key project components include a duplex sump pump station with redundant high water alarms and alternating pump operation controls, a septic tank system designed per AASHTO 17th Edition and ASTM specifications with H-25 loading capacity, a drain field with 40-foot width, sanitary cleanout details, and a rock riprap dissipator. The specifications require Schedule 80 PVC pipe with tracer wire and warning tape for force mains, perforated HDPE N12 pipe for cooling tower drainage, 5000 PSI concrete reinforcement per ASTM standards, and KOR-N-SEAL sealant. All technical drawings are provided at various scales with detailed elevation and dimension specifications for proper installation and operation.
The document specifies that contractors are responsible for providing and installing all control systems necessary to meet the sequence of operations for the pump station, which includes five operational levels triggered by water level alarms. Pipe and fittings for inlets and outlets are noted as not included in the septic tank specifications. The septic tank and drain field design criteria are based on Mid-Michigan Health Department standards. Material specifications reference MDOT 6A standards and require adherence to manufacturer specifications for tie-downs and equipment installation. The project drawings are dated 24-0569 and prepared by Matrix, indicating this is a professional engineering design package for competitive bidding purposes.
