The purpose of this amendment is to:

1) Revise Section C to clarify that fire work is not included. Remove "fire" and any mention of fire service connections, Fire Protection

Devices, and fire-protection systems. A revised

SECTION C

-Description/Specification/Requirements is attached.

2) On page 57 of the solicitation, section L.2

REQUIRED SUBMISSION DOCUMENTS, Remove mention of "fire" under subfactor B. Replace section with:

Sub-Factor B - Licensing/Certifications -

Philadelphia Water Department (PWD) Regulation

403 requires approved backflow protection on domestic service connections, annual testing by

City certified personnel. All offers must include documentation and proof of city certifications for the backflow technician

(domestic) and plumber. MUST provide copy of license/certification or name, license number, status, issue/expiration dates, and company name.

3) Provide responses to all questions received as follows:

Question 1: Section L.2, Sub-Factor C requires three relevant prior projects performed by the offeror. If the offeror proposes a subcontractor or technician who will perform the certified backflow testing and holds the relevant project history, does that experience count toward the offeror's Sub-Factor C rating, or must the projects be performed directly by the offeror entity itself?

Answer 1: Yes. The Government will accept and evaluate the relevant past performance references of the proposed subcontractor, provided that the offeror clearly distinguishes which past performance examples belong to the

Prime Contractor and which belong to the subcontractor.

Question 2: I don't see FAR 52.219-14

(Limitations on Subcontracting) in the Section

I clause list. Can you confirm whether it applies to this acquisition, and if so, what percentage of the work must be self-performed by the prime?

Answer 2: The clause is not applicable.

Question 3: Base-year M&R has no NTE and a different unit of measure (10 Each) than all four option years (1 Lump Sum NTE $10,000).

Should the base year also be NTE $10,000 -i.e., Do you want $1,000/device - or should we price the actual expected per-device cost?

Answer 3: It is estimated that up to 10 units may need to be replaced during the base year.

Price the actual expected per-device cost.

Question 4:Can the Government provide the approximate number of backflow assemblies at each of the 17 locations, and their sizes and types?

Answer 4: Please see the attached inventory list.

Question 5: If that detail is not available, should quoters price the annual testing and certification line on an assumed device count?

If so, we would appreciate the count the

Government would like all quoters to use, so that quotes are directly comparable.

Answer 5: Please see the attached inventory list.

Question 6: Please provide the total number, sizes, types, and domestic/fire designation of the backflow devices at each listed property.

The Device Inventory Table currently shows these device-level fields as TBD.

Answer 6: Please see the attached inventory list.

Question 7: Whether the scope includes testing the sprinkler systems themselves or only testing and certification of backflow devices serving fire-protection systems.

Answer 7: Please see the attached revised
