About this file
The document is a detailed Questions and Answers (Q&A) spreadsheet for a federal solicitation to purchase and install new water flow meters and sensors for the International Boundary and Water Commission (IBWC) Falcon Field Office in Texas. The Q&A file addresses technical specifications for a project involving five new water flow meters and thirteen sets of ultrasonic water flow sensors to be installed on penstock generators and hollow jet valves. Key technical clarifications include acceptable sensor configurations, training requirements, electrical and wiring specifications, display requirements (a 15-16 inch electronic display in the control room), and installation details.
The related federal contract opportunity is a 100% small business set-aside Request for Quote (RFQ) with solicitation number FY255701046, targeting instrument manufacturing businesses. The procurement seeks to purchase and install new flow meters and sensors at the Falcon Field Office in Falcon Heights, TX. Critical procurement details include: site visits are recommended (closed July 8, 2025), quotes are due August 5, 2025, at 3:00 pm MST, and the award will be made to the lowest-priced technically acceptable offeror. Vendors must be SAM.gov registered small businesses, and the evaluation will consider technical acceptability, technical approach, and past performance. The contract will require performance and payment bonds equal to 100% of the contract price.

| ID | DATE | DOCUMENT | PAGE | SECTION | SUBJECT | QUESTION | ANSWER |
| 5 | 3/4/24 | 1- PWS.pdf | 3 | 2.1 D | The Contractor shall supply/install/calibrate five (5) New Water Flow Meters with Thirteen (13) Set |
of Ultrasonic Water Flow Sensors Mounted Type or Dilled Type, Three for each Penstock Generator
| and Two for each Hollow Jet Valve | The specification states that there will be 13 sets of transducers. This would mean 3 sets of transducers on the 3 Penstock pipes and 2 sets on the 2 Holow Jet pipes. With our preferred solution we will achieve less than 1% inaccuracy with 2 sets of transducers on each line for a total of 10 sets instead of 13, and it will be lower cost. Is this acceptable? | Please provide in your submittal wherever you think would provide the accuracy required on this project 1% sounds great. If you think 10 set of transducers provide this tyope of accuracy would be reviewed. | ||||
| 8 | 3/4/24 | 1- PWS.pdf | 1 | 1.4 A.4 | The Contractor Shall Install/Update/Compile Data of New Water Flow Sensors with New | |

| 14 | 6/20/25 | 1- PWS.pdf | 4 | 2.1 G | "The Contractor shall provide/install at least 16 inches (Or Bigger) Electronic Display to monitor the |
new meters data, and this display would be installed at Power Controllers Main Control Room., This purchased by the Contractor. The main function of this Display is to provide information/data about monitor display quality and specifications will be evaluated by IBWC Team prior to be approved and
| water flow rate on every Penstock or Hollow Jet Valves" | Will a monitor this large fit in the space available in the control panel, or is this a desktop display in the control room? | There is enough space to install the 16" digital display mounted on the control panel. | ||||
| 15 | 7/8/25 | 1- PWS.pdf | 4 | 2.1 G | "The Contractor shall provide/install at least 16 inches (Or Bigger) Electronic Display to monitor the |
new meters data, and this display would be installed at Power Controllers Main Control Room., This purchased by the Contractor. The main function of this Display is to provide information/data about monitor display quality and specifications will be evaluated by IBWC Team prior to be approved and
| water flow rate on every Penstock or Hollow Jet Valves" | Is this 16 inch diagonal or 16 inch width? | 16 inch width rectangular. | ||||
| 15 | 7/16/25 | 1- PWS.pdf | 4 | 2.1 G | "The Contractor shall provide/install at least 16 inches (Or Bigger) Electronic Display to monitor the |

| water flow rate on every Penstock or Hollow Jet Valves" | In the site walkthrough the site personnel indicated that 16 inch sized monitor is not required. For them it is acceptable to have amonitor that fits in the panel and shows the 5 flows with accumulator reset capability. They said it could be smaller than 16 inches. Is the 16 inch size required? | The size can be close to 16 inches not smaller than 15 inches because is too small to display the information/data. | ||||
