SITUATION:
Enbridge Inc. (formerly Spectra) chose BOND to install a five-mile natural gas pipeline extending from Dedham to West Roxbury along with accompanying meter station. BOND self-performed the pipeline installation and meter station to complete the project on time and on budget. The scope of work included the installation of a 24-inch crossing under MBTA tracks, 48-inch crossing under the I-95 highway and installation of five miles of pipe as well as a new meter station through three highly congested residential communities.
CHALLENGES:
- Pipe installation located within several densely settled residential neighborhoods
- Maintaining traffic flow
- Dewatering
- Stringent permit restrictions
- Protester opposition for pipeline construction
SOLUTIONS:
- Established communication protocols with area residents to keep them informed of construction activities
- Performed installation at off-peak hours to minimize traffic delays
- Developed dewatering system to control groundwater levels and eliminate threat of contamination
- Developed protocol for protester coordination which was then adopted by Enbridge
RESULTS:
- Minimal impact to neighborhood residents
- Newly installed pipe provides National Grid with the additional capacity needed to add to their existing system
- Zero safety incidents and zero downtime related to protester disruptions
