Amendment 0002 to Solicitation Number 19MX5326Q0028

Preventive Maintenance Service for Water Treatment System Q&A

TECHNICAL QUESTIONS

ATTACHMENT A, Statement of Work Q1. Confirm the volume of potable water consumption (in cubic meters).

A1. It is around 110 cubic meters daily. (Based on the last four months consumption.

Could be different during the year the rest of the year)

Q2. Total number of drinking fountains.

A2. Plate type: 25. Bottle filler: 21. Refrigerators with water dispenser: 63.

Q3. Confirm that the potable water, after undergoing ultrafiltration, passes through the carbon filters and is not chlorinated again.

A3. Water is chlorinated after it passes through the carbon filters.

Ultrafiltration – Potable Water and Treated Wastewater -Page 28

Q4. Confirm the volume (m³) of treated wastewater consumed.

A4. We don’t have a waste water treatment plant, so it doesn’t apply. We have a City-water recycled and storm water treatment plant (for irrigation and toilets), and depending on the season of the year, we could be using around 40 cubic meters daily. (Based on the last four months consumption. Could be different during the year the rest of the year)

ADMINISTRATIVE QUESTIONS

Q5. Should the requested documents be uploaded as a single file, or does the platform allow uploading multiple files? Also, what is the maximum file size in megabytes?

A5. Quotes should be submitted to MexicoCityGSOSolicitations@groups.state.gov. You can send several emails, divided in price and technical section.

Q6. Section 1.7 (Pricing) of the RFQ specifies that services are to be performed on a monthly basis. However, we regularly provide water treatment maintenance services for numerous DOS missions worldwide, and these services are typically performed on a quarterly, semi-annual, or annual basis. Could you please confirm whether the monthly service requirement may be waived or revised?

A6. Continuous monitoring is required. At the very least, one service per month is required; even more if the system so requires.

Before we go through the solicitation, I would like to point out the following important notes:

Statements

The statements made here do NOT change the solicitation. All changes will be made by written amendment to the solicitation.

Amendment

It may be necessary to amend (change) the solicitation during the solicitation period for such reasons as:

• The need to change the closing date for receipt of offers;

• The need to correct ambiguities; or

• Changes in quantity, specifications, or delivery schedules.

Government implements the Fair Release of information, in other words, what you tell one, you must tell everyone.

Questions

The Questions & Answers document will be posted on the Contract Opportunities in the SAM.gov website.

Solicitation The solicitation is divided into the following 4 sections:

Afterward, we explained the required format for quote submissions, as outlined in the Attachment A statement of Work. We also reminded all participants of the importance of being registered in SAM.gov prior to submitting their proposals to ensure consideration.

Additionally, the evaluation factors detailed in Section 4 were reviewed.

Conclusion
