1. Question: Because of the unknown (grit/sludge/debris/etc…) and quantity of materials in the existing Aeration and Anoxic Tanks to be cleaned out, we hereby request one of the following payment items be implemented for a fair bid process:

- Provide a quantity of material to be handled, removed and disposed of properly for hazardous and non-hazardous materials to be included in the lump sum price.

- Add an Allowance Item for Unforeseen Work to be billed against on a Time/Material

Basis.

- Provide Quantity and Description under a Unit Price Basis.

Response: See the revised Statement of Bid Items which provides for a unit price line item for grit removal.

2. Question: Reference is made to Drawing 210-GI-2 note: Exterior Wall Patching.

Because of this work being unknown, please quantify this work with quantities to be included in the lump sum price (please be specific for spall repairs and depth of different crack repairs), or to be performed under an Unforeseen Allowance Item, or to be performed under Unit Pricing.

Response: See the revised Statement of Bid Items which provides an allowance for concrete wall repairs.

3. Question: Reference is made to the existing aeration supports at the bottom of the tanks. Please clarify that once cut; can the remaining anchors/rods stay as is or will they be required to be patched over?

Response: The anchors/rods are stainless steel. After cutting flush with the floor of the aeration tank, the anchors/rods can remain in place.

4. Question: Reference is made to Section 13 50 06 2.1 Pipes, Tubes and Fittings (A.). The specified

Schedule 80 SS 316 Pipe is an extremely heavy wall for this application. A typical installation through-out the Sewage Plants in NYCDEP, Nassau & Suffolk Counties require a much lighter wall (e.g. sch 10). Please reconsider the wall thickness here. The lighter it is, the easier it’ll be to handle and install – making the installation cost less money. Also, please clarify the joints. We are requesting to have the option to weld them or install SS Victualic couplings with the proper heat rated gasket.

Response: Schedule 40 316 Stainless Steel will be accepted instead of Schedule 80. Schedule 10 will not be accepted. Victaulic couplings with the proper heat rated gasket will be accepted. The Contractor has the option to weld joints or use Victaulic couplings.
