RE: ADDENDUM #2, RFP NO. 20260423, WATER ELEVATION MONITORING SERVICES – ANNUAL
CONTRACT
Firms are hereby notified that this addendum shall be made a part of the above-named proposal and contract
documents. The following are issued to revise/clarify the proposal and contract documents, and these items shall
have the same force and effect as the original proposal and contract documents. Proposals to be submitted on
the above-specified date at Purchasing shall conform to the revisions and clarifications as listed herein.
ITEM # 1- QUESTIONS/ANSWERS
Q1: The RFP specifies that some stations will need cellular communications, and some will need
satellite because they are remote. The cost difference between cellular and satellite can be
significant across many stations. Is there an estimated number of stations that are remote enough
to require satellite communications?
A1: To our knowledge, none of the proposed stations will require satellite communications for day-to-day
monitoring. That said, certain locations may be considered high priority for storm event monitoring and
thus would benefit from satellite communications capabilities in the event regional cellular
communications are interrupted. It is anticipated that the vast majority of the stations will rely exclusively
on cellular communications, with a select few coastal monitoring sites utilizing satellite if such option is
available.
Q2: Is there a future plan to add additional sensors to these stations? Sensors could include
meteorological parameters (air temperature, pressure, relative humidity, precipitation, wind
velocity), flow sensors, and/or water quality sensors (temperature, pH, dissolved oxygen,
turbidity, chlorophyll, blue-green algae, etc.)
A2: There are no immediate plans to add more sensors to these stations, although the desire to do so
may arise in the future, as need is determined and financial resources allow. That said, the ability to
support multiple other types of sensors is not a baseline requirement for this RFP.
This addendum is binding and is to be considered as if contained within the original proposal documents of RFP
No. 20260423. Firms are required to acknowledge receipt of this addendum on their proposal forms.
