“DCA believes that safety is paramount in any construction project, but this is especially true with underground projects,” said Rob Darden, Executive Vice President at DCA. “Gas distribution contractors know the hazards that come with the job, and we appreciate the opportunity to show OSHA the latest and greatest equipment, technologies, and practices related to underground construction projects. We thank AEM for hosting this important event.”
