Vendor Q and A 260417.docx

Vendor Q and A Photos & Site Documentation Q The Hoosier National Forest section mentions "photos are attached in the contract package" — where can we find these? Are they available for all sites or just Hoosier?

A This is an error. Photos are not available currently.

Q Are as-built drawings or equipment diagrams available for the existing EWS stations (especially those being repaired or upgraded)?

A No, as-built drawing and equipment diagrams are not available.

Q What are the brands, make, model, etc. (and cable lengths if appropriate) of the currently installed EWS components?

A All currently installed EWS were assembled by American Millenium Corporation, Inc (AMCI).

Sensors & Equipment Q For the "repaired EWS" at Tipsaw (Hoosier) — who is responsible for making the repair, and will the repaired unit be shipped to Contractor or is it already on-site?

A The contractor will work with the EWS manufacturer for repair. Repaired unit can be shipped to the Forest.

Q For Indian, Celina, and Saddle (Hoosier) — the water level sensors are listed as "government-furnished." Will GFE be on-site at time of work, or does Contractor need to coordinate receipt/delivery logistics?

A Yes, the water sensor levels will be on-site at time of work.

Q What is the make/model of the existing EWS at all upgrade/repair sites (Deer Creek, Springs Valley, Timber Ridge, Vesuvius, Lake Sherwood)?

A The current EWS units were assembled by AMCI.

Q What type of water level sensor is expected at new installs (Wakeley, Dutchman, Campton)?

A Contractor should work with the EWS assembler/manufacturer to determine the appropriate sensor for the application.

Q For specific sites, the solicitation states the Contractor is responsible for repairing EWS equipment. If the equipment is not repairable, will there be a change order allowed to cover the cost of replacement equipment or are those costs expected to be included in our pricing?

A Costs should be included in pricing submitted.

Q What infrastructure (e.g. conduit runs from gauging station to water) is in place for sensor installations and is any such in need of repairs/replacing?

A Varies. Conduit for existing EWS may be present. New EWS will require installation.

Q What requirements are there if trenching on the dam is required to install conduit runs?

A More clarification is requested.

Q What data logger/RTU is expected?

A Contractor should work with the EWS assembler to determine the appropriate data logger for the application.

Data Transmission Q For sites specifying "satellite communications" — what satellite platform is in use? GOES DCP, Iridium, or other?

A The existing EWS communicate with the AMCI SatAlarm service.

Q Many of the sites require “Verification of satellite communications” and “Calibration with the service provider while on-site”. Who is the service provider and where is this data being reported to and collected?

A The current service provider is AMCI. Monitoring data can be viewed on the AMCI SatAlarm web portal.

Q For sites that allow "satellite or cellular" (Wakeley, Campton) — is there a preferred vendor or existing account the USFS wants to use?

A AMCI remote monitoring equipment is the basis of design for EWS.

Q For the Dutchman site the Solicitation states “collect and transmit water level data and rainfall data via satellite or cellular communications” and then “shall be available for remote monitoring at any time and provide real time data to the Forest Service”. First, where does the data need to be transmitted to, and secondly, does a remote connection to the station, being able to view real time data, count as adequate or must the data be delivered to some receiving platform (e.g. computer/webpage system) for processing and display in real time?

A The data must be viewable in the AMCI SatAlarm web system.

Q For Mark Twain sites — the Adcon RG1 gauges use their own telemetry network. Who manages the Adcon base station, and will Contractor need to log into the Adcon system for calibration?

A Contractor will need to work with the onsite Forest Service staff for calibration.

Alarm System Q What constitutes "confirmation that the alarm system is working correctly"? Is Contractor expected to trigger a test alarm through the service provider, or simply verify threshold configuration?

A The alarm system shall measure and transit accurate and precise reservoir level elevations.

Q Who sets the alarm parameters — will USFS provide these before Contractor arrives on-site, or is Contractor just confirming the capability exists?

A The alarm levels will be provided by the USFS. Contractor should work with the remote sensing service provider to very the alarm levels are recorded.

Site Access & Coordination Q For Wayne National Forest (Tecumseh relocation to Sand Run) — is Sand Run Dam in any permitting or environmental review status that could affect installation timing?

A No Scope Clarity Q For "site restoration" at Tecumseh — is there a standard USFS spec for backfill/grading, or is contractor judgment acceptable?

A The site will be restored to match neighboring, undisturbed areas.

Q The SOW mentions 18 dams, but the table only lists work for 18 sites including 5 Mark Twain rain gauge services. Are the Mark Twain sites counted among the 18, or is this 18 dams + 5 service sites?

A Yes, the 5 Mark Twain sites are counted among the 18.
