“ERRG did an outstanding job on this project.  The project manager was very responsive, creative and worked tirelessly to complete all aspects of the project with professionalism and a positive attitude.  [ERRG] had a very can-do attitude towards solving problems and overcoming issues over the duration of the project.  ERRG worked very well with other contractors on the shipyard and proactively coordinated all aspects of the field effort.  ERRG personnel were very qualified and familiar with all requirements of construction projects, including EM-385, storm water, and dust control requirements.  I would highly recommend ERRG.  ERRG’s outstanding performance on this project was the basis of the Navy’s recommendation for recognition and selection as SBA Region 9’s 2011 Prime Contractor of the Year.
