About this file
This is a Questions and Answers document from a site visit addressing a natural gas leak detection survey contract. The document clarifies scope, deliverables, equipment, qualifications, and submission requirements for prospective contractors.
The survey covers approximately 167,000 linear feet of combined distribution and service lines within a military installation, excluding base housing. Leak detection work is limited to exterior systems and ends at building tie-ins (meters); no interior building work is required. The government will provide shapefile/map data of lines and meter locations; contractors are not required to perform independent GPS tracing. Contractors must supply their own specialized equipment and mobile devices, though the government provides baseline mapping. Personnel must meet PHMSA and 49 CFR Part 192 Subpart N Operator Qualification (OQ) requirements, with any nationally recognized OQ training service acceptable (EWN, ITS, MEA). Approved detection equipment includes Remote Methane Leak Detectors, Combustible Gas Indicators/Detectors, Optical Gas Imaging Cameras, or Air Sampling Wands; the government will not dictate specific equipment brands. Deliverables include an electronic report submitted to the Contracting Officer's Representative within 30 calendar days of survey completion, followed by two paper PDF copies within 45 calendar days. On-site access requires security clearance documentation; a multi-day pass will be issued on day one, with gate access estimated at 15 minutes to 1 hour. No specific proposal format beyond pricing per linear foot is required.

1. Will leak detection be required inside any of the buildings, or does our scope stop at the building tie-ins?
Leak detection ends at building tie-ins (meter).
2. Do we have an estimate of the total linear footage for the service lines outside?
I’m assuming those are in addition to the 167,000 LF of distribution line mentioned, but wanted to confirm.
167,000 LF of lines are from where it enters the installation and feeds to all facilities, excluding base housing.
3. Will we have to trace and locate each system on a GPS map?
We will provide shapefile/map of lines to include meter locations.
4. What GPS software would be required or preferred for this project?
We will provide shapefile/map of lines to include meter locations. No GPS software preference.
5. Please outline the data submission procedure (e.g., analog vs. digital, contractor-provided system vs. client-supplied devices).
Electronic/emailed report to COR within 30 calendar days of survey completion followed by two paper (PDF) copies of the report with 45 calendar days.
6. Will the successful bidder be responsible for supplying specialized tablets or mobile devices?
The government will not provide contractor with tablets or devices to complete leak detection. Exception is shapefile/map of lines and meters.
7. Is there a preferred third-party Operator Qualification system or service, or will any of the nationwide Operator Qualification services be acceptable (EWN, ITS, MEA, etc.)?
PHMSA and 49 CFR Part 192 Subpart N mandates ensures individuals can correctly perform tasks. All listed training and qualifications will suffice.
8. Please provide the required list of OQ tasks for the survey.
OQ tasks for natural gas leak detection surveys ensure technicians can safely identify, classify, and report gas leaks, complying with PHMSA and 49 CFR 192 regulations. Key tasks include conducting leakage surveys, operating detection equipment, classifying leaks, and identifying Abnormal Operating Conditions.
9. Truck Access: Assuming all required documents are in hand, how long is it estimated to take the technician to get through the gate on Day 1 of the survey?
It varies each day depending on visitor center/commercial gate traffic. It could be as little as 15 to 1 hour.
10. Will a multi-day pass be allowed to be issued on Day 1 for ease of access for the duration of the survey?
A multi-day pass will be given on day one of survey.
11. Are the INFICON Irwin and Heath Odorator recognized as approved, compliant devices for the 2026 survey scope?
Industry approved standard equipment such as Remote Methane Leak Detector, Combustible Gas Indicators/Gas Detectors, Optical Gas Imaging Cameras, or Air Sampling Wands may be used. We as the customer can’t dictate specific pieces of equipment to use to conduct the survey.
12. Will the maps be supplied as hard copies, digital formats, or something else?
We will provide shapefile/map of lines to include meter locations.
13. Scope – Interior vs. Exterior Work Does the required leak detection survey include work inside buildings, or is the scope limited to exterior systems and up to building tie-in points?
Survey ends at building tie-ins. Entry into facilities should not be required.
14. Pipeline Quantities The solicitation references approximately 167,000 linear feet of distribution and service lines. Can you confirm whether this figure represents the total combined length, or if a breakdown between distribution lines and service lines is available?
167,000 linear feet includes distribution and service line.
15. Mapping Requirements Is the contractor expected to perform full GPS tracing/locating of all gas systems, or is the requirement limited to utilizing existing base maps and providing annotated reports indicating leak locations?
We will provide shapefile/map of lines to include meter locations.
16. Proposal Format / Submission Expectations Aside from pricing per linear foot, is there a preferred format or specific structure the Government would like vendors to follow when submitting their quotations (e.g., technical approach, assumptions, staffing, etc.)?
No
