This is a product specification document for survey monuments, caps, and markers used in wetlands and surveying applications. The document details six distinct product types: drivable aluminum monuments designed for wetlands with 3" diameter aluminum survey caps and 2" diameter aluminum pipes (30" long) featuring cast aluminum base points and permanent ceramic magnets; drivable steel monuments with stainless steel rods (9/16" diameter, 30" long) and forged bronze caps with powerful magnets and stainless steel flanges; aluminum drive-in survey monuments with 3" diameter series 6000 aluminum caps and 1" diameter aluminum pipes (30" long) with ceramic magnets and optional stamped center points; 2" diameter aluminum caps for 5/8" rebar featuring series 6000 aluminum construction with SureGrip plastic insulators and deep hex sockets; 2" diameter aluminum caps for 3/4" rebar with identical features to the 5/8" variant; and steel nail markers (3" length with 1" convex tops) imprinted with "SURVEY MARK" for use in blacktop. All products emphasize durability, corrosion resistance, and precision marking capabilities with optional stamping specifications.

This specification document supports a pre-solicitation sources sought announcement (Solicitation Number 140F0S26Q0021) issued by the Department of the Interior Fish and Wildlife Service for survey monuments, caps, and markers. Interested vendors must respond to Robert_Sung@fws.gov with their CAGE Code, Unique Entity ID, and evidence of manufacturing capability or authorized reseller status for equipment comparable in price and quality to Berntsen products, with successful U.S. survey work experience required for resellers.
