Current bid date of 4/30 overlaps with bid date for NAVFAC MACC

B60 project also at PNSY. Due to this and as PPI responses are still forthcoming, kindly request extension to 5/14/26 for final bid date for this project to ensure proper vendor coverage and ability to distribute PPI responses and accommodate associated updates once received.

See proposal due date extension.

As PPI responses have not yet been issued and the responses will need to be evaluated and acted upon by all vendors and contractors pricing this project, we request that the proposal submission date be extended to May 21, 2026, to allow for that effort to be effectively completed. It is also noted that some PPI responses may derive follow-up questions that will need to be resolved prior to proposal submission.

See proposal due date extension.

MD-103 Demolition

Key Notes

MD-103 states that there will be no demo in Room M under the base scope. However, per memorandum issued 12NOV2025, the base scope

(option 8) as identified on the correction table, line 0001O is considered option 8. Please confirm if the mechanical demo on

MD-103 is base scope or not, as the interchanged CLINs and options utilization is not clear.

Memorandum issued 12 Nov 2025 is clear as it changes Option 8 (formally

CLIN 009) to a CLIN 0001O which is now an item under the base bid.

BWRO from

SWRO

Cartridge

Filters

Please confirm that the cartridge filters prior to the BWRO are needed. Since the feed from the

BWRO is directly from the SWRO these cartridge filters will likely cause more harm that good. There will be increase hydrological issues, wear and tear of cartridges, and potential risk of adding contaminants via use. Ideally, these could eliminated from the scope/design.

The cartridge filters shall remain in the scope and design
