Natural Gas Piping Infrastructure — From Assessment to Commissioning


[01]

Determining the Solution

We will meet with you on site to review the plans for your project and determine what is required to install the propane or natural gas infrastructure. Our team will review the capacity of the existing infrastructure and plans for appliances and uses, recommending solutions that will realize your vision.

This includes recommendations for appliances, as well as piping infrastructure sizing. We will highlight any modifications that may be required to remain within code, and ensure the safe operation of your appliances. The findings will be detailed in a written report that includes our recommendations.

Utility Coordination

Determining the status of existing natural gas utility infrastructure that connects the building to the mains can be time consuming. This is especially true of projects that require relocation of your gas service or meter, or for locations that have gone unoccupied for a period of time.

D&S can engage the utility with the information about the project to ensure the appropriate capacity from the utility, coordinate installation of the infrastructure, location of the meter, and ultimately tie in to the gas piping at the building. Realizing the timeline on these efforts is key to project success. D&S will be the liaison with the utility for your project to keep on track.

Permitting & Inspection

D&S has licensed Gas Fitters as key members of its staff. Reviewing installations to provide guidance on the need for permits, and the installation compliance with permits is a key strength of our team. We are able to obtain permits and provide staff on site for all stages of propane and natural gas inspections to help the process move smoothly and in compliance.

Whether you are renovating your home or business, converting appliances to propane or natural gas, or adding a gas fired generator or supplemental gas heat, it is crucial to understand the local code requirements that govern your project. Our team is licensed by the local code authority in all of the jurisdictions in which we operate.

Installation

Our staff of licensed Journeyman and Master gas fitters are available to install the gas house-line piping for all your appliance needs. The staff is also qualified by the manufacturer to install specialty piping such as corrugated stainless steel (CSST), which is excellent for complicated installations or high capacity appliances such as instant water heaters or fireplaces.

The result will be appropriate piping stubs with regulators, pressure tested and commissioned to code. From natural gas piping and propane systems to appliance hookup, we handle the full installation scope.
