The Government intends to procure, under only one responsible source, where no other suppliers or service will satisfy the agency requirements. The Naval Facilities Engineering Systems Command, Hawaii (NAVFAC Hawaii) is conducting market research to determine if other potential products/services can provide for a centrifugally cast fiberglass-reinforced polymer mortar (CCFRPM) pipe that has the equal performance and listing/approval requirements as the HOBAS pipe (CCFRPM pipe), manufactured by HOBAS Pipe USA, Inc., 1413 E. Richey Road, Houston, Texas 77073-3508. The alternate product/service must meet the following requirements and specifications:

1. Centrifugally cast fiberglass-reinforced polymer (CCFRPM) pipe, manufactured and tested in accordance with ASTM D3262.
2. Pipe sizes shall be 24-inch (DN 600, 25.8-inch OD) and 42-inch (DN 1050, 45.9-inch OD) nominal diameters.
3. Manufactured by the centrifugal casting process to result in a dense, uniform, non-porous, corrosion-resistant, consistent composite structure.

10. Glass Reinforcement: The reinforcing glass fibers used to manufacture the components must be of the highest quality commercial grade E-glass filaments with binder and sizing compatible with impregnating resins.
11. Silica Sand: Sand must be minimum 98% silica with a maximum moisture content of 0.2%.
12. Additives: Resin additives, such as curing agents, pigments, dyes, fillers, and thixotropic agents, etc., when used, must not detrimentally affect the performance of the product.
13. Elastomeric Gaskets: Gaskets must meet ASTM F477 and be suitable for the intended service.
