Z--GWMP MEMORIAL AVE IRRIGATION EXTENSION

Amendment / Modification

Amendment 05 to solicitation 140P212600060 has been issued.

This amendment addresses an additional question received regarding documentation of experience.

• The government has clarified that there is no required form for documenting experience. Offerors should use their own form to document their experience.

Amendment / Modification

This amendment (0004) addresses additional questions received regarding the solicitation:

• Water Access: There is no water source along the NPS-stretch of Memorial Avenue. The irrigation extension must tie into Arlington National Cemetery's existing irrigation system to function as one continuous system.
• Existing Connection: There is no existing spigot or stub-out to tie into; the extension must connect to ANC's existing system.
• Irrigation Controller: The existing (ANC) system uses Hunter-brand controllers. It is currently unknown if the irrigation extension can function off the existing controllers.

This amendment provides clarifications to questions, impacting bidder understanding of system connections and water sources.

Bidders should consider these clarifications when developing their proposals, particularly regarding the integration with the existing Arlington National Cemetery irrigation system and the unknown compatibility with existing controllers.
