Questions & Answers

RFQ 19MX5326Q0016 for Security Upgrades

TECHNICAL QUESTIONS

Q1 In the price list, item 019-119-219-319 indicates stainless steel fencing. This material is not a standard product; that is, it must be custom-made according to the models requested in the SOW. Since this type of material can be 3 to 4 times more expensive than conventional commercial steel fencing, it is important to clarify whether the fencing should be stainless steel or mild steel. Mild steel is the conventional, commercial steel that we have used in some of your projects:

Should the fencing be stainless steel or conventional commercial steel?

A1 Fencing should be conventional commercial steel

Q2 Also, please consider that stainless steel and mild steel, being different, can cause some aesthetic problems when welded together. Stainless steel stains black, and to remove this stain, an acid is used that dulls the stainless steel's shine. On the other hand, stainless steel requires a manufacturing period of at least two or three weeks. Manufacturing is done using laser cutting and waterjet cutting:

Should the perimeter structure of windows, some doors, sliding gates, etc., be made of rectangular tubing (PTR) or profiled tubing?

A2 Yes, perimeter structure should be rectangular or profiled tubing as we need it to be reinforced.

Minutes from Site Visit to 19MX5326Q0016 Security Upgrades on March 19, 2026.

Attendees:

10 people from 5 prospective offerors attended the Site Visit.

The following staff from the Requesting Office and the Procurement

Section attended the visit.

o Miguel Rojas / Contracting Officer Representative (COR) o Veronica Tecuatl, Contracts & Procurement Supervisor o Jesús González, Contracts Assistant

Introduction

The Contracts team welcomed the participants, introduced the Contracting Officer Representatives and explained the itinerary and the places that will be visited.

Purpose:

The purpose of the site visit was to brief all prospective offerors about the solicitation and to see the locations where the different residential properties where security upgrades have been installed. It was also important to highlight that doing business with the U.S. Government differs from commercial practice because the solicitation and award processes are regulated under Federal Acquisition Regulations (FAR).

Minutes disclosure:

Attendees were notified the Site Visit minutes would be posted on Sam.gov under Contracts Opportunities to ensure other vendors who could not attend the walkthrough are not disadvantaged.

General directions for this site visit:

• This Site Visit was conducted in Spanish and English to ensure all the attendees had a thorough understanding.

• Attendees received instructions not to ask questions individually to any of the Site Visit leads. Instead, all questions were asked aloud so everyone could hear both the question and the answer.

• After the introductions, the site visit was led by the COR.

• Attendees visited 3 residential properties that are considered a general sample of the services that are required, which are described in section 1 of the RFQ.

• The Contracting team explained that questions asked during the Site Visit will be compiled and included in the Question and Answer (Q&A) document, along with questions received via e-mail in accordance with the RFQ instructions which will be also posted on Sam.gov. It was explained that a multiple award IDIQ contract will be awarded.

Attendants’ attention was called to the following:

Statements:

The statements made during the site visit do NOT change the solicitation. All changes would be made by written amendment to the solicitation.

Amendments:

Amendments are intended to clarify or modify the solicitation. They may originate from:

• Issues raised by suppliers during the pre-proposal stage, at the conference, site visit, or at any time;

• To modify the dates on which proposals are received from suppliers;

• To clarify ambiguities, or;

• To change dates, dates of delivery, or specifications.

All amendments will be posted on Contracts Opportunities on sam.gov. The U.S. Government implements the Fair Release of information, in other words, what you tell one, you must tell all.

Questions

Prospective Offerors were requested to submit their questions via email to be compiled and included in the Q&A file.

The Q&A will be posted on Contracts Opportunities in Sam.gov.

Site Visit

Prospective Offerors toured 3 residential properties according to the date and schedule below:

o Thursday, March 19, 2026, 10:00 am

Locations:

1. Bosque de Reforma 295, CDMX, Mexico.

2. Fray Payo de Rivera 130, CDMX, Mexico.

3. Seneca 142, Polanco II Secc, Miguel Hidalgo

Prospective Offerors were reminded about the following:

o Offerors must not contact the Requesting Office for any issue or question related to this process.

o An active SAM registration is required to submit a proposal.

o This is a lowest priced technically acceptable solicitation process that will be based on Section 4, Evaluation Factor, which was reviewed during the Site visit.

o To be acceptable and eligible for evaluation, proposals must be prepared in accordance with Sections 3 and 4 and shall meet all the requirements set forth in the other sections of this solicitation.

o The U.S. Government intends to evaluate offers and award a contract without discussions with offerors. Therefore, the offeror’s initial offer should contain the offeror’s best terms from a price and technical standpoint. However, the U.S.
