About this file
This is a technical specification document for public sanitary sewerage gravity piping prepared by Herbert, Rowland & Grubic, Inc. for the Weaverland Valley Authority's North Earl Street Low Pressure Sanitary Sewer Extension Project (Project No. 011361.0461). The specification details the installation requirements for approximately 270 linear feet of 2-inch low-pressure sanitary sewer main via directional drilling, approximately 100 linear feet of 1.5-inch LPSS lateral piping, one 5-foot diameter cleanout manhole, connection to existing manholes, and related restoration work. The project scope includes piping materials (PVC, ductile iron, and plastic pipe options), manhole specifications, flexible pipe boots, cleanout frames, bedding and cover materials, and comprehensive installation requirements including trench preparation, pipe laying procedures, bedding placement, backfilling, compaction, and quality control testing. Installation must follow industry standards including ASTM and AWWA specifications, with particular emphasis on watertight connections, proper sloping, and minimum separation distances between components. Field quality control includes inspection by the Engineer prior to and immediately after bedding placement, with provisions for removal and replacement of work that fails to meet specifications. Bid submission deadline is 10:00 AM local time on June 30, 2026, via the PennBid Program, with bid security required in the form of a certified check or bid bond of not less than 10 percent of the total bid price.
The specification document establishes detailed technical requirements for materials, products, and execution standards but does not address pricing terms, project budget, funding sources, or set-aside designations. The document includes comprehensive reference standards and submittal requirements for product data, test reports, manufacturer instructions, and quality-control documentation. No pre-bid meeting is scheduled; however, site visit opportunities will be coordinated through PennBid. Written questions regarding the bidding documents must be submitted through PennBid to Herbert, Rowland & Grubic, Inc. by 2:00 PM on April 27, 2026, with telephone inquiries prohibited. The specification applies to Contract #1 and requires coordination with PPL for existing utility pole and electric line removal, abandonment of existing sanitary sewer facilities, and installation of two Authority-supplied simplex grinder pumps.
