Holland Engineering was selected to provide engineering, design and procurement services for DTE’s Traverse City Area Natural Gas Reinforcement Project (TCARP) in Grand Traverse, Benzie, and Leelanau counties.
DTE’s objective is to increase the reliability of the natural gas system serving Grand Traverse, Benzie, and Leelanau counties and to strengthen their existing service to approximately 91,000 customers across Northern Michigan. Supported by the Michigan Public Service Commission, the 22-mile project entails looping two existing pipelines to add a second natural gas supply source to the area to help ensure minimal customer disruptions during routine maintenance or in the unlikely event of an emergency.
We provided engineering and design services for thirteen (13) new and existing facilities and connections needed to reinforce the Traverse City and Leelanau markets through looping portions of the existing 10” Lincoln-Traverse City and 8” Frankfort Pipelines. These pipelines will then be connected to natural gas transmission volumes from the company’s Kalkaska Compressor Station through an existing gathering line to be converted to dry service. The project is currently nearing the end of the AFC phase.
The contracted scope included:
- Pre-design as-builts survey of the facilities
- Survey facilities and pipeline
- Environmental services
- Mechanical engineering and design
- Civil and structural engineering and design
- Electrical and instrumentation engineering and design.
