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 provides detailed technical specifications and construction drawings for critical infrastructure components including a duplex sump pump lift station with dual pump redundancy, a sanitary sewer system with cleanout details, a septic tank system designed for H-25 loading with 0.0' to 3.0' earth cover, and a drain field measuring 40' in width. The sump pump station includes five operational levels with low water alarms, pump sequencing controls, and high water alarms, with both pumps capable of running simultaneously. All piping specifications call for Schedule 80 PVC with tracer wire and warning tape for force mains, and perforated HDPE N12 pipe for cooling tower drains. The septic tank and drain field design comply with Mid-Michigan Health Department criteria and are manufactured per AASHTO 17th Edition and ASTM specifications.
The specifications detail concrete pad requirements of 6'x6' with #4 rebar at 8" on-center spacing in each direction, 5000 PSI concrete at 28 days, and pipe and fitting materials meeting ASTM A-615 and A-496 standards. Tank covers must be sealed with 1-1/2" EZ-STIK or equivalent material. The document notes that pipe and fittings for inlets and outlets are not included in the specified scope, casting and adjustment to finish grade are not included, and the contractor is responsible for providing and installing all building controls necessary to meet the specified sequence of operations. The project reflects municipal infrastructure requirements for a nature center facility in Michigan.
