General Electric

  • Location: Auburn, Maine
  • Project Description: Construction of HVAC and plumbing systems for a 40,000 sq ft electroplating addition to the existing manufacturing facility.
  • Challenge: In addition to a tight construction schedule, tie-ins to existing systems could not impact production

St Mary’s Regional Medical Center Emergency Department

  • Location: Lewiston, Maine
  • Project Description: Construct new, fully designed 20,000 sq ft emergency department comprised of renovated existing hospital space and an adjacent new addition.
  • Challenge: Project required renovation in areas surrounded by occupied, sensitive space.

Castle at Brickhill

  • Location: Portland, Maine
  • Project Description: A spectacular 65,000 sq ft brick building constructed in 1860 as housing for Maine youth offenders, Brickhill is in the process of redevelopment for medical offices and related activities. The building along with the surrounding campus has commanding views of Portland and the ocean.
  • Challenge: In addition to its heavy construction, this Design/Build mechanical project is a challenge because the developer has required, for cash flow considerations, that a minimum of infrastructure be installed until the remainder of the facility is developed and leased. This has had significant impact on system and equipment selections; modular and add-on components have been incorporated.

Central Maine Health Care

  • Location: Lewiston, Maine
  • Project Description: Formerly a shoe manufacturing factory, this late 19th century heavily constructed industrial building was converted to medical offices, back offices and a nursing school to support nearby Central Maine Medical Center.
  • Challenge: Another Design/Build mechanical project, the challenges centered around the extensive fenestration and exposed brick walls of the original building and how it frustrated efficient heating and cooling.

Maine General Hospital

  • Location: Augusta, Maine
  • Project Description: Construction (with Design/Build mechanical) of a 51,000 sq ft medical office building.
  • Numerous redesigns of the interior space delayed the start of this project without corresponding extensions of the occupancy date leaving a construction window of less than 180 days from commencement of sitework to occupancy.

Central Maine Commerce Center

  • Location: Augusta, Maine
  • Project Description: Central Maine Commerce Center was a 3-year project to convert a 350,000 sq ft light manufacturing facility to an office facility housing State and State related tenants and offering consolidation of departments in a single location for operational efficiency along with much improved energy efficiency.
  • Challenge: A Design/Build mechanical project, this demonstrates the capacity of our Company to handle a large project from start to finish. More significantly, each tenant brought its own highly compressed construction schedule. Throughout, no deadlines were missed.

Rumford Hospital Consolidated Inpatient Unit

  • Location: Rumford, Maine
  • Project Description: This work involved the construction of a new 18,000 sq ft wing and an 8,000 sq ft renovation to the existing hospital. The project included expansion of the operating room and construction of new patient rooms. New mechanical systems accompanied the new addition and substantial integration with the older facility was required.
  • Challenge: Integration of the old and new facilities was challenging as expected but our knowledge and experience in health care work proved valuable to the client. Although the project came with a mechanical design, it was, for us, substantially a Design/Build mechanical project.
