What DeIulis Brothers Construction Company does

DeIulis (VP/CFO/General Counsel), and William J. DeIulis (VP/Senior Project Manager). The company provides pre-construction consulting, construction management, and general contracting services, with a distinctive capability of self-performing key trades including selective demolition, site work, concrete, masonry, and rough and finish carpentry through its own permanent skilled workforce.

The business serves six market segments across Massachusetts and broader New England: Healthcare (with Partners Preferred Contractor status at Mass General Brigham for projects up to $10M since 2008), Education, Municipal/Government, Commercial, Religious, and Housing (multi-family, assisted living, and premium single-family). Documented project values range from approximately $2.8M to $16MM+, including Salem Hospital's new main entrance lobby ($14MM, completed 2023), St. Mary's High School Gateway and STEM Building ($15.3MM), LEO Preschool ($16MM+, completed 2025), Alden Mills Fire Station ($13MM+, completed 2025), and the LEED Gold-certified East Boston Branch Library ($9.8M, completed 2013, recognized by the Boston Society of Architects).

Revenue is generated through lump sum, guaranteed maximum price (GMP), and negotiated construction contracts awarded via competitive public bidding or private negotiation. The firm holds three affiliated real estate companies (Pasquanna Developers formed 1976, Central Plaza Associates formed 1981, DeIulis Properties formed 1997) that create internal development pipelines. Revenue is not publicly disclosed; the firm has no external investors, parent company, or funding events on record and operates as a privately held Massachusetts corporation.
