Interested vendors may submit pricing in addition to any pamphlets or specifications sheets; however, as stated before, this is only for research purposes and is not a formal solicitation for quote or proposal. Interested vendors may contact the POC listed in this notice to submit interest or ask questions.

It is recommended that interested vendors possess significant experience with mobilizing similar products in hard to access locations due to the geography of Guam/Marianas region. If a solicitation related to this notice is issued at a future date, interested vendors can expect delivery and mobilization to be a significant factor in selection/performance of the contract.
