PROJECT DESCRIPTION: Pompey’s Pillar Iron Filter, Media, and Tank Replacement Solicitation No. 140L3626Q0023

New Questions and Answers

Question 7. Existing iron filter tank details, including manufacturer, model, diameter, height, pressure rating, connection sizes, and any available photos or as-built drawings.

Answer 7. See attachment 3 and 4.

Question 8. Existing iron filter tank details, including manufacturer, model, diameter, height, pressure rating, connection sizes, and any available photos or as-built drawings.

Answer 8. See attachment 3 and 4.

Questions and Answers

Question 4. The current filter media type, required media quantity, bed depth, gravel support layers, and whether the Government requires the same media or will accept a contractor-recommended equivalent suitable for iron and manganese removal.

Answer 4. Contractors shall base their quote on the existing system configuration and assume replacement in kind, including the current filter media type, media quantity, bed depth, and gravel support layers, to the extent information is available in the contract documents or can be reasonably inferred from site conditions.

Where specific parameters are not defined, contractors shall assume industry-standard design criteria appropriate for iron and manganese removal in groundwater filtration systems. The intent is to establish a common basis for bidding; therefore, no deviations from the specified or assumed baseline design shall be included in the initial proposal.

Contractor-recommended alternatives (e.g., equivalent or enhanced filter media) may be submitted after contract award for Government consideration. Any such recommendations must:

• Include sufficient technical justification demonstrating equal or improved performance for iron and manganese removal

• Be compatible with the existing infrastructure (e.g., vessel configuration, hydraulic loading rates, backwash requirements)

• Not introduce increased operational complexity, maintenance burden, or lifecycle cost without clear benefit

Contractors are advised that any deviation from the existing system configuration may be subject to regulatory review and approval. As such, acceptance of proposed alternatives could result in additional review time and potential delays to implementation. The Contractor shall account for this risk, and no schedule or cost adjustments will be considered unless expressly authorized through a formal contract modification.

PROJECT DESCRIPTION: Pompey’s Pillar Iron Filter, Media, and Tank Replacement Solicitation No. 140L3626Q0023

All deviations are subject to Government evaluation and approval, and no changes shall be implemented without prior written authorization from the Contracting Officer.

Question 5. Whether the two hydropneumatic tanks are required to be fully replaced, or whether rehabilitation is acceptable if inspection determines they are serviceable.

Answer 5. Both hydropneumatic tanks shall be fully removed and replaced under this contract. Rehabilitation, reuse, or continued service of the existing tanks is not acceptable, regardless of inspection results or perceived condition.

Contractors shall base their proposals on complete replacement and shall include all labor, materials, and incidental work necessary to provide fully operational and integrated tanks within the existing system.

This requirement reflects the Government’s intent to ensure long-term reliability, regulatory compliance, and consistency of system performance. Accordingly, no deviations from this requirement shall be included in the contractor’s proposal.

Post-award requests to deviate from full replacement will not be routinely considered and would require compelling justification. Any such request, if submitted, remains subject to Government evaluation and approval at the sole discretion of the Contracting Officer through a formal contract modification.

Question 6. Analytical results further confirm treatment deficiencies, with manganese concentrations measured at 0.552 mg/L at the clearwell effluent - well above the recommended level of 0.05 mg/L - and 0.074 mg/L at the entry point to the system.

Can the effluent be discharged into the septic tank drain? Or will the high concentration of manganese discharged need to be sent into a separate holding tank and trucked off the site once full?

Answer 6. Use of the onsite septic system for disposal of liquid waste generated under this contract is not permitted.

All waste materials, including liquid waste, shall be managed, transported, and disposed of in accordance with all applicable federal, state, and local laws and regulations.

Disposal shall be the sole responsibility of the Contractor.

The Contractor shall assume that offsite disposal at an appropriately licensed facility is required and shall include all associated costs in their proposal, including handling, transportation, treatment, and disposal.

Questions and Answers

Question 1. What are the dimensions of the room where the tanks and treatment systems are located?

Answer 1. Approximately 20' X 20'

PROJECT DESCRIPTION: Pompey’s Pillar Iron Filter, Media, and Tank Replacement Solicitation No. 140L3626Q0023

Question 2. What are the water demands of the system? Is the system supplying campgrounds?, housing?

Answer 2. Average demand of 1300 gallon per day with max demand of 6000 gallon per day. System supplies the Pompey's Pillar Interpretive Center.

Question 3. What are the specs on the current well and pump in place?

Answer 3. The existing pump is a Goulds 33GS20 with an Aquavara AVII Variable speed pump controller. The pump supplies 35GPM to the filtration system. The well has a total depth of 33 ft with a static water level of 4.5 ft.
