Statement of Work
Ref: 2026-001 • Standard Business Template
Overview
This agreement dictates that all medical gas installation services shall be performed in strict adherence to the NFPA 99 Health Care Facilities Code and all applicable local Authority Having Jurisdiction (AHJ) requirements. The Installer assumes responsibility for the integrity of the brazed joints and system components installed under this scope, provided that the Client ensures a clean, controlled environment free from contaminants that could compromise the medical-grade piping during the construction process. Any deviations from the approved engineering blueprints requested by the Client must be documented via a formal Change Order to ensure continued compliance with life-safety protocols.
Upon completion of the installation, the system must undergo a formal verification process by an independent third party; the Installer’s liability for the functional performance of the system terminates once the third-party verifier issues a passing certification. The Client acknowledges that any modifications to the system after certification, or failure to perform routine maintenance according to manufacturer standards, effectively releases the Installer from any liability regarding patient safety or system failure. This contract serves as a shield against claims arising from secondary equipment failure or facility-managed gas supply issues.
Third-Party Verification Failure
If a system fails the final particulate or cross-connection test due to site conditions outside your control, you could be forced to pay for expensive repeat testing fees.
Copper Material Volatility
The price of Type L and K ACR copper can fluctuate daily. Without a price adjustment clause, a long-term clinic build can become a net loss before you even break ground.
Purge Gas Continuity
If the general contractor fails to provide a secure area for nitrogen cylinders or interrupts your purge during brazing, the resulting oxidation requires a total system flush at your expense.
What is a Medical Gas Installer Contract?
A Medical Gas Installer Contract template is a specialized agreement that defines the scope of NFPA 99 compliant system installation. It outlines responsibilities for brazing, nitrogen purging, and third-party verification. The document protects installers from liability regarding system contamination and ensures they are compensated for specialized materials and testing requirements.

Why Medical Gas Installers need a clear contract
Medical gas installation is a high-stakes specialty governed by NFPA 99 life-safety codes. Unlike standard plumbing, a single contaminated joint can lead to system-wide failure or patient risk. A written contract is essential because it defines the boundary between your installation and the facility's existing infrastructure. It ensures you are not held responsible for source equipment failures you did not manufacture or for particulate contamination caused by other trades. Because the materials, such as cleaned-for-oxygen ACR copper, are significantly more expensive than standard pipe, the contract must protect you from price volatility and unapproved scope changes. It establishes your role as an ASSE 6010 professional rather than a general laborer, protecting both your certification and your bottom line.
Real-world scenario
A medical gas installer is hired for a four-room dental surgery expansion. They perform the rough-in and start the nitrogen purge for brazing. The general contractor, rushing to stay on schedule, allows the drywall team to close the walls before the third-party verifier arrives. When the verifier finally performs the standing pressure test, a small leak is identified at a joint that was likely bumped by the drywallers. Because the installer did not have a contract clause requiring a signed site-readiness form before wall closure, the GC demands the installer pay for all drywall demolition and repair to find the leak. The installer spends three days of unbilled labor and five hundred dollars in materials to fix a problem they did not cause, losing the entire profit from the contract.
🛡️ What this contract covers:
- ✓Phase 1: Comprehensive site assessment and detailed piping layout design compliant with NFPA 99 standards and facility engineering specifications.
- ✓Phase 2: Installation of medical-grade copper piping, silver-brazed joints, zone valves, and terminal outlets with continuous nitrogen purging to prevent oxidation.
- ✓Phase 3: Rigorous system testing including standing pressure tests, cross-connection checks, and coordination with an independent third-party verifier for final certification.
Best practices for Medical Gas Installers
Define the Testing Boundary
State clearly that your price includes one initial third-party verification and that all subsequent tests due to external damage are billable.
Specify Material Standards
Explicitly list that all piping must meet ASTM B819 standards and stay capped until the moment of installation to prevent hydrocarbon contamination.
Establish Tie-in Limits
Document that you are not responsible for the integrity or cleanliness of the existing facility piping beyond the new point of connection.

Frequently Asked Questions
Who is responsible for the final third-party verification and associated certification costs?
The installer ensures all work meets code requirements and passes initial pressure tests, but the client is responsible for hiring and paying an independent ASSE 6030 verifier to perform the final legal certification required before patient use.
