District Regulation Rebuild Program Overview

California, Statewide 

The District Regulation (DREG) Rebuild Program is a multi-year, on-going assessment of existing natural gas utility transmission and distribution regulator station assets across California. Kleinfelder has been contracted to provide detailed engineering, design, and estimating services in support of the effort to increase safety, mitigate operational issues, or bring aging infrastructure up to current codes and standards. These design projects can range in size from single customer services off high pressure pipelines, up to multi-district regulation stations that feed natural gas to hundreds of downstream customers. The scopes also range from retrofit of existing assets to full rebuild of station.

To date, Kleinfelder has completed over 500 DREG rebuild design projects under this program, with another 59 estimated projects for 2023. The typical timeframe for the design of the project is 90-120 days, however, Kleinfelder has successfully expedited projects in as little as 30 days for expedited construction.

Kleinfelder’s Solution

Kleinfelder brings a comprehensive team approach to design projects. Project planning begins with records research on existing facilities and the preparation of design alternates to uncover potential obstacles, and to strategize on addressing them early before designs are too mature to modify easily. Kleinfelder’s design team also perform field visits  early in the design process so that drawings and documentation are developed and vetted against actual conditions. This leads to a well-defined scope of work, and results in fewer changes during construction.
