We are Building Engineers whose mission is to provide clients with cost effective, energy efficient, and sustainable building designs. Allied Engineering has been providing superior engineering design services based in Maine since 1958.

  • We are a leader in energy efficient building design. Since before the term was even defined, we’ve been practicing green building design for years.  We have LEED Accredited professionals in each engineering discipline.
  • Over the years we’ve forged relationships with a long list of repeat clients in education, government, healthcare, cultural arts, hospitality, institutions, manufacturing, commerce, industry and retail.  We also have strong working relationships with architects, contractors and specialty consultants.

“All projects have been handled with the utmost leadership, professionalism and engineering abilities. Allied’s leadership and technical abilities have also been exceptional for commissioning large heating ventilation and air conditioning systems and digital controls in complex laboratory and vivarium spaces.”
