It appears the hardware sets section of the spec is cut short.

They specify a lot of hardware but there is nothing showing which hardware goes with which door. Please issue a completed door hardware schedule.

Drawing A-601, and related drawings, provide the relevant door schedules for this project. Also, see the revised specification attached (Attachment N- 08 71 00 R1)

Drawing M-

467680

Contract drawing M-505 depicts a floating decanter guided by vertical decanter guide posts anchored at the tank bottom and supported at the top. However, spec section 467680 specifies a floating decanter restrained by three stainless steel cables.

Please confirm the intended decanter guidance system (guide posts vs. mooring cables) and provide the required operating water range.

Drawing M-505 depicting guiding posts is correct. Please see the revised Attachment Q- 50 03 01 R1. The operating range will be approximately 21 feet and will be field adjusted.

Spec Section 43 21 15

2.1.A.8

Specification states that pumps shall fit inside the 6" nominal well casing diameter, however, the Grundfos model 625S pumps specified are 8.31" in diameter and will fit a minimum well diameter of 9".

Please advise.

The well casings are a nominal 12 inches, not 6 inches as stated in the specifications. See revised specification 43 21 13 (Attachment O- 43 21 13_R1).

I noticed that a coconut carbon is specified, and it is required for the product to be produced in the United States.

Coconut carbons are not produced in the US, but rather imported. I would need to know whether we should provide an imported coconut GAC product or a coal-based product manufactured in the US. For this application, we would typically recommend a coal-based catalytic carbon for optimal performance

While coconut shell-based carbon is preferred for this application, acid-rinsed coal-based carbon can also be used. Attached is the revised specification (Attachment L- 43 3113.13 10)

"Drawing A-102 as notes call outs for Steel Guardrail, while Structural detailed drawings S- 402 & S-503 Call for FRP.

Please clarify the desired material.

Specifications call for Molded Mesh grating while Notes on Drawing S-003 call for 2” Pultruded Grating T-3300 or T- 5000 .Please clarify the desired material.

Contract drawing M-101 shows an 8” BWS pump discharge while schematics on drawing MI605 shows 10” BWS pump discharge. Please confirm the size."

Drawing MI605 is correct. The pump suction is 10 inch. Drawing M-101 is being revised to show the 10" BWS pipe size. (Attachment P- M101-R1)
