Comment:

Volume 1 (Mandatory Documentation Required With the Proposal) of Solicitation W912PF25QA092 provides as follows:

“e. The Offeror shall provide proof that the contractor/company holds a valid Società Organismo di Attestazione (SOA) Attestation demonstrating qualification in a category and classification appropriate for the scope of this project. The relevant category SOA Certification is Classifica IV-BIS in category OG10.”

It is our understanding that:

1. SOA certification is a requirement under Italian public procurement law (previously Legislative Decree No. 50/2016, the Codice degli Appalti, and more recently Legislative Decree No. 36/2023, the Codice dei Contratti Pubblici), for contractors participating in Italian public works procurements exceeding €150,000;

those procured by the United States Government under the U.S. Federal Acquisition Regulation (FAR).

We note that Solicitation W912PF25QA092 relates to a U.S. Army Corps of Engineers (USACE) procurement conducted pursuant to the FAR in connection with a U.S. Government facility located in Italy.

Questions:

We respectfully request confirmation on the following points:

1. Whether SOA certification is in fact required from all Offerors (including U.S.-based entities); and

2. If so, whether the SOA certification must be held directly by the Offeror itself, or whether it may alternatively be satisfied through a related third party, such as: (i) an Italian affiliate within the Offeror’s corporate group; or (ii) an Italian subcontractor or joint venture partner of the Offeror.

We appreciate your prompt clarification to ensure compliance with the solicitation requirements.

1. Yes, the requirement for a valid SOA Attestation in the specified category and classification applies to the entity performing the construction work. For a U.S.-based prime contractor, this requirement must be met by the entity that will be performing the on-site construction and installation work (e.g., a qualified Italian subcontractor).

2. The SOA certification must be held by the legal entity performing the work that requires such certification under Italian law. The solicitation is hereby clarified: A prime contractor may meet this requirement through a key subcontractor who holds the required SOA. If this approach is used, a letter of commitment from the subcontractor must be included in Volume I.

2 27-Aug-25 Solicitation 30/48 VOL 1

SOA Requirement (Cat OG-10 Cl IV-BIS). Performed similar/equal project but we do not have the appropriate Category/Classification required in the Solicitation. Will our proposal be taken into consideration if we submit/provide a Partnering/Teaming Pre-Agreement with a suitable subktr?

Yes. See response to Q1. If an Offeror as a prime contractor does not hold the required SOA certification, its proposal will be considered compliant if it includes a firm letter of commitment from a key subcontractor that holds the required SOA certification (Classifica IV-BIS in categories OG9 or OG10). The letter of commitment must be included in Volume I and will not count against any page limits.

QA092

31 of 48 vol,4 past performance

We respectfully request clarification on whether past performance involving the installation of Uninterruptible Power Supply (UPS) systems (with same size and complexity of project requirement) may be deemed acceptable as relevant experience in lieu of Battery Energy Storage Systems (BESS) installations.

As stated in Volume IV, Relevancy Definition, the Government will consider projects "more relevant if they demonstrate experience with...

Installing and integrating Battery Energy Storage Systems (BESS)..."

While UPS and BESS systems share some technological principles, BESS integration into a microgrid is considered a distinct and more complex capability. Offerors may submit UPS projects for consideration, but the burden is on the Offeror to demonstrate the relevance to the SOW.

Projects involving BESS will be considered more relevant.

Scope of work specifies the use of lithium-ion batteries. We would like to inquire whether the Government would consider the use of sodium-nickel battery systems as an acceptable alternative, provided they meet or exceed the required performance, safety, and certification standards outlined in the solicitation.

Sodium-nickel batteries offer several advantages over lithium-ion technology, including:

Higher safety (no risk of thermal runaway or fire) Longer cycle life (up to 6,000 cycles) Wider operating temperature range (0°C to +300°C) Reduced environmental impact (no rare earth elements) Compliance with key standards, including UL 9540A, UL 1973, IEC 62984, and EN IEC 61000-6-2/6-4 We have attached a technical report comparing sodium-nickel and lithium-ion systems, including performance data, certifications, and operational considerations

Sodium-nickel battery systems is feasible if it meets the requirements of the SOW. See SOW Rev 1 Section D509090. Section has been revised to remove the lithium ion battery requirement.

Offeror request to know the brand of the System present on the site, receiving the topological and wiring diagrams and the narrative/sequence of operations as well

Longare MGC is not yet operational. The MGC has the preliminary configuration in non-redundant platform and it is based on an ABB Optimax temporary license, containing optimization capabilities, but it shall be specialized and configured in redundant platform for Longare Microgrid. Wiring and topological diagrams will be sent in a new Zip folder named Attachement 01.The narrative of the description/sequence of operations is already described in SOW D503006 (page 24); it needs to be developed to adapt it to the configuration of the new Micro Grid with the requied permanent license.

51 4-Sep-25 General, Time extension

Contractor request for a 2- week time extension to allow adequate time to review solicitation package and obtain offers from subcontractors due to delayed receipt of drawings and other missing information in the documents. We require all technical question to be answered by the Government in order to engage with our engineering team and develop the technical narrative.

RFQ has been extended to 22 SEPT 2025

52 4-Sep-25 Design 24, 38, 42, and

Looking the conceptual design drawings received with the Amendment1 we note that in the event of a power failure of the commercial line, the BESS will have to directly power the critical loads without load interruption and will have to counter-power the microgrid. In this regard, we need to know what is the acceptable power failure time frame of the no-critical loads in counter-powering the microgrid.

In the event of a power interuption from the utility's network, the BESS will have to instantaneuosly support all loads connected to the substations. Moreover, after approximately 30 seconds, both (400kVA each) generators located in Bldg 40 will start automatcally and the BESS/generators will share the installtions load. Upon the generators picking up the entire installation load, the BESS will transiotion to idle mode.

53 4-Sep-25 Solicitation 23 of 48 52.211-10

The solicitation provides a 332 calendar date while Attachment 1, SOW para. 2.3 identifies a total design time of 242 calendar days. While we understand the design schedule may be accelerated if approved by the COR, this would leave an Offeror 90 days to perform construction, install, and connect the BESS systems. Based on our exerience, procurement/delivery of the BESS system alone takes upwards of 8 months. A realistic period of performance for a project of this size and scope should reflect 664 calendar days to ensure design, procurement, delivery, installation, connection, and testing are performed efficiently.

Request the Government change the 332 calendar date to 664 calendar days

The Government finds acceptable a a 6-month extension for the construction period (not design). Therefore the total of days for this project will be 242 calendar days for design (no change) and 270 (vs 90 days) days for construction (construction time is not referenced in the SOW), for a total of 512 calendar days.

Two out of four intervention areas fall within the Vincolo Paesaggistico D.Lgs 42/2004, Vincolo Idrogeologico forestale R.D. 3267/1923 and the Vincolo di Destinazione Forestale (art.15 L.R.52/78).

The project also includes the installation of four lithium-ion battery energy storage systems (BESS).

Is ISO 14001:2015 environmental certification required for the company to participate in the tender given the presence of these constraints and hazardous elements?

If not, will the presence of an ISO 14001:2015-certified company have a greater

No, ISO 14001:2015 is not required for the company. Constraints will be properly managed by the DOR. Hazardous element surveys will be performed/managed by specialized laboratory firms as subcontractor of the main contractor.

No, the presence of an ISO 14001:2015 certified company will not have a greater impact on the assessment.

57 04 Sep 2025 How many milliseconds of network failure are accepted for the BESS to take charge of privileged loads?

Per SOW Section D509090 ensure continuity of service without gaps or interruptions.

58 04 Sep 2025 What are the minimum warranty requirements for BESS?

The minimum warranty must be atleast 3-years for the defects in the appliances. The manufacturer may also extend the warranty. This factor will be considered in the technical evaluation.

59 04 Sep 2025 Should the 4 BESS units supply only the LV loads of their MV/LV substation, or should they also supply, in emergency situations, all the loads of the rest of the MV network in islanded operation (i.e., the part of MV grid downstream PI)?

Per SOW Rev. #1 Section D503006 In the event of a power failure from the utility's network, the BESS must be able to power the network in Island mode MV operation.
