Question No. Sheet or Reference Question Response Amendment

1 Can the use of Siemens hardware and WinCC be utilized in lieu of the use of Allen Bradley as specified in the construction specifications?

The construction specification does not require Allen- Bradley exclusively. Division 40 accommodates multiple SCADA hardware and software manufacturers, including, but not limited to Allen-Bradley, Siemens, GE and Schneider Electric, provided the proposed system meets the specified performance and compatibility requirements. The Division 40 specifications are performance based and accommodate alternate SCADA hardware and software platforms provided the proposed equipment meets the specified functional, performance, compatibility, communication and integration requirements. Bidders are not precluded from proposing an equivalent solution under the current specification. Any equivalent solution would need to demonstrate compliance with the specified salient characteristics and be evaluated through the submittal process.

2 Can key personnel serve in dual positions? I.e. Superintendent - also service as Quality Control? Yes 4

3 What is the gallon limitation for use of water - especially when utilizing water for flushing and chlorination purposes?

Park Water use: flushing, disinfection and other potable uses only.

Non-potable water availability contingent on drought conditions and availability; potential to utilize surface water of the lake if coordinated with CODEQ and BOR;

contractor to coordinate.

5 Are offerors required to submit General References with their proposal? If so, is there a template? Yes - Template was uploaded to SAM.gov 4

6 Are offerors required to submit Section K with their proposal? Yes 4

7 What is the period of performance? 550 Calendar days 4

8 Could we please get a copy of the radio path survey that was completed prior to the project going out for bid?

This information will be shared with the awardee after award. 4

Question No. Sheet or Reference Question Response Amendment

9 Did the engineers confirm that the Aviat Aprisa SR+ radios will handle the required Allen Bradley data transfer rates?

Neither Allen Bradley nor Aviat Aprisa SR+ are specific requirements of the project – they were used as basis of design. The design does not seek to prescribe any particular make or model (PLC or radio) – the contractor may submit any equipment they feel best suits the needs of the system.

DOR is not aware of a published “data transfer rate” for Allen Bradey PLCs inherent to the model or ethernet IP protocol – data transfer rate is primarily dependent on the amount of data and frequency of data being sent, which more is dependent on specific configuration and timing of messaging than a protocol or brand. The minimum data update rates specified (every 15-30 sec depending on the application) are not demanding of a high speed connection; payloads are expected to be on the order of kilobytes, not megabytes for daily SCADA functions. The SR+ is the basis of design used for the radio interference analysis report requested by NPS during design; this model exemplifies a modern digital radio with advanced modulation schemes that are expected to outperform the existing analog radios.

Lake Fork Lift Station – Drawing I04.231 – Lake Fork List Station RTU (LFLS) Panel Layout & BOM lists a 24VDC Solar Charger and 12VDC Batteries, 105 AH on the Bill of Material however, there is not any solar panels listed on the BOM nor does drawing I04.230 show the existing lift station as a solar site. Is the Lake Fork Lift Station to be a solar site with the installation of the new packaged lift station? If so, a Rohn antenna tower would be more stable than a typical antenna mast. Please advise.

Lake Fork Lift Station does not need any solar, charger or batteries, utility power will be available. The only solar site in this project is Iola tank.

Specification section 40 67 00.2.02.A. states “Enclosure Manufacturer: Hoffman Engineering Company” however, all of the drawings for the Panel Layout and BOM list Saginaw. Should enclosures be Saginaw or Hoffman? Also, Saginaw part numbers are for Stainless Steel enclosures however, no NEMA rating is listed in the specification. Should all enclosures be stainless steel with a NEMA rating of NEMA 4X?

Neither Hoffman Engineering Company nor Saginaw are specific requirements of the project – they were used as basis of design. The design does not seek to prescribe any particular make or model – the contractor is responsible to submit a product that meets the requirements

Regarding the Aviat Aprisa SR+ VHF radios – we had a Teams conference call with Aviat, the Aprisa radio manufacturer, and they were not confident that their VHF radios would be able to handle the terrain at the park or the bandwidth required for Allen Bradley PLC’s, including the Micro870 PLC’s specified for this project. Would you like us to propose an alternative communication media that will handle the bandwidth and topography requirements?

See response provided in question 9 4
