The sanitary Drain pipe sizes, drain types and drain sizes between drawings P-132, P-431 and P-933 have a few discrepancies.

As an example there are two floor drains identified as 3” FD-2P on drawings P-132 and P-933 and the same drains on drawing P- 431 are identified as 3” FD-1P. Please review the three drawings and provide consistent drain pipe sizes, drain sizes and drain types.

Subject plumbing drawings have been reviewed and revised for consistency.

80 Volume 13b – Page 17 M-134 Drawing M-134 identifies section details M-231 A2 and C3. From review of the drawings M-231 is not part of the drawing the set.

1/2" copper trap primer piping may be encased in structural slabs. If run below slab, encase per Detail A4/S-803.

96 NA NA NA Does this project contain a reverse osmosis requirement?

Membrane system is specified as nanofiltration.

Membrane system requirements are defined in Bid Specification Section 43 32 56 and in the Bid Drawings.

97 Specification 43 32 69 Membrane Systems

Paragraph 2.2

The specifications require the Membrane System Supplier shall have at least 10 years of experience designing, constructing, and supplying nanofiltration or reverse osmosis systems for municipal water treatment within the United States. Many Nano Filtration Membranes are used for commercial purposes and the requirement for municipal WTP experience use eliminates a large number of membrane suppliers.

Would the Government consider eliminating the requirement for experience in municipal Water Treatment and replace with “10 years of experience designing, constructing and supplying nano filtration or reverse osmosis systems within the United States”?

Sufficient competition exists, the municipal experience requirement remains. The membrane system supplier shall have the experience per the specifications and the membrane system supplier shall supply membrane elements that can treat water with the water quality listed in Table 2 (Supplement 1 of specifications) and produce permeate with water quality meeting requirements of Table 4 (Supplement 3 of the specifications).

The supplier shall supply membrane elements from a membrane element manufacturer with at least 3 municipal nanofiltration water treatment plants using the proposed membrane elements that have been operating for at least 5 years and with capacities of at least 5 mgd within the United States.

Paragraph 2.4 has been revised to clarify the requirements.

Please clarify.

PENDING

RESPONSE

103 Drawing Volume

DP104 the buried 8” FBS (filter backwash supply line) is depicted as HDPE, but Supplement 1 to specification 40 05 13 indicates that buried FBS should be epoxy lined ductile iron pipe/fittings.

Please confirm that the buried filter backwash supply (FBS) piping should be epoxy lined ductile iron pipe/fittings.

Exposed and concrete encased FBS shall be epoxy lined ductile iron.

Drawing DP106 includes a note that reads, “Two 2” LL containment pipe with 1” LL carrier tube to injection point. This note appears to be in agreement with para. 2.9 of specification 40 05 13;

however, both appear to be in conflict with the information provided in Supplement for the buried liquid lime piping.

Please confirm the proper materials to be used for this piping.

Buried liquid lime piping shall be tubing inside PVC carrier piping.
