AIS_SUBMITTAL_MATERIAL_CHECKLIST.pdf

This is an American Iron and Steel (AIS) Material Checklist for Road Sewer Projects prepared by the Pipeline Design Division in May 2023, applicable to work by the Washington Suburban Sanitary Commission (WSSC) in Maryland. The checklist outlines required materials and products for the Laurie Drive Sewer Rehabilitation project, which involves the repair, rehabilitation, or replacement of 1,171 linear feet (0.22 miles) of defective sewer mains, 1,006 linear feet (0.19 miles) of defective sewer laterals, and three manholes located in the Paint Branch Basin. Sealed responses must be submitted via WSSC's eProcurement Portal at https://procurement.opengov.com/portal/wsscwater prior to 2:00 pm on Tuesday, December 23, 2025, with late responses not accepted.

The checklist identifies specific AIS-compliant materials required for the project, including manhole frames, covers, and bolts; reinforced concrete pipe (RCP); reinforced concrete; ductile iron pipe (DIP); saddles; and couplings/adapters, with certificate numbers to be provided for verification. Precast manholes are noted as not required. All materials must comply with American Iron and Steel requirements, ensuring domestic manufacturing standards are met for this publicly funded sewer infrastructure project in Maryland.
