Rubicon Builders

What Rubicon Builders does

Rubicon Builders, LLC is a private New England construction services firm headquartered in Mansfield, Massachusetts, founded in 2013 by President Jim DiGiorno. The firm operates with 11–50 employees across Massachusetts, Rhode Island, and Connecticut, and is led by a founder with a near 40-year construction career that includes ~15 years as a Project Executive at Consigli Construction. Rubicon delivers projects through four integrated service lines: Construction Management (fee-based CM often beginning at feasibility or schematic design), Preconstruction (estimating, value engineering, scheduling, constructability, site logistics, safety planning), Design-Build (single-point-of-accountability integrated delivery claimed to be ~30% faster than design-bid-build), and General Contracting (lump-sum competitive-bid delivery via prequalified subcontractors).

The firm's delivery model is supported by Project-Specific Safety Plans developed for each project by OSHA 10/30-hour and first-aid/CPR certified team members, and by an integrated preconstruction-to-occupancy workflow. Customer acquisition is founder-led and relationship-driven, generating a referral-heavy pipeline; the firm states that the majority of its clients are nonprofit organizations (community health centers, YMCAs, food banks, veteran services, faith-based and educational nonprofits), with additional segments in healthcare and senior living (Beth Israel Deaconess Hospital-Plymouth, SALMON Health & Retirement, Harbor Health Services), academic and private institutional (Fay School, Summit Montessori, Anna Maria College, Our Lady of the Valley), multi-family and mixed-use developers (Chestnut Commons, SORA Revere, Abbey Road), corporate industrial (O'Brien & Sons, Plansee USA, Hydroid / HII Unmanned Systems), and public sector (Town of Plymouth, Town of Mattapoisett, Xfinity Center / Live Nation). Project scale ranges from small interior renovations up to ~290,000 sq. ft. senior living campuses, with multi-phase engagements (e.g., MetroWest YMCA, BID-Plymouth, Kingsbury Club) creating repeat-customer relationships.

Revenue is generated through project-based contracts (one-time lump-sum GC and Design-Build, and fee-based CM and Preconstruction engagements), typically spanning multi-year billing cadences. Pricing is quote-based and not publicly disclosed. The firm is privately held with no disclosed funding rounds, ownership stakes beyond the founder, parent company, or M&A activity.

Revenue model

1. General Contracting (GC) Projects: Competitive bid-based contracts based on completed project design; traditional lump-sum or stipulated-sum delivery for commercial, institutional, healthcare, and public-sector projects.
2. Construction Management (CM) Fees: Fee-based construction management services often beginning at feasibility or schematic design stage, continuing through occupancy, with alignment of interests between CM firm, client, and design team.
3. Design-Build Contracts: Single-point-of-accountability integrated design-and-construction contracts with established construction costs prior to detailed design; ~30% faster than traditional design-bid-build per Rubicon.
4. Preconstruction Services: Standalone or pre-engagement services including cost estimating, value engineering, scheduling, constructability analysis, site logistics, safety planning, and exploratory work.

Core offering

Rubicon Builders is a New England construction firm providing Construction Management, Preconstruction, Design-Build, and General Contracting services to nonprofit, healthcare, academic, senior living, multi-family/mixed-use, corporate industrial, and public-sector clients. The firm is engaged early in project development — from feasibility and schematic design through construction, occupancy, and post-occupancy — with hands-on collaborative leadership from its founder and a focus on occupied-environment construction.

Product overview

Rubicon Builders is a New England construction firm offering a unified suite of four core construction delivery services rather than a software platform with add-on modules: Construction Management, Preconstruction, Design-Build, and General Contracting. Together, these service lines cover the full project lifecycle from feasibility and early design involvement through construction, occupancy, and post-occupancy support, and are supported by Rubicon's hands-on collaborative leadership approach and Project Specific Safety Planning.

Functional benefit

Products and services

• Construction Management Construction Management (CM) service in which Rubicon is engaged early in project development to assist with feasibility studies, schematic/conceptual design, and design/preconstruction shaping of budget, schedule, and design, followed by comprehensive management of all construction aspects through occupancy. Targeted at clients undertaking their first complex capital project or those seeking fee-based alignment with their design team.
• Preconstruction Preconstruction services providing cost estimating, value engineering, scheduling, constructability analysis, site logistics, safety planning, and exploratory work to increase predictability and set the project up for success during Construction. Delivered collaboratively with owners and design teams, often as a standalone engagement or as part of an early-involvement CM or Design-Build engagement.
• Design-Build Integrated Design-Build (DB) delivery in which Rubicon provides a single point of accountability, an experienced design-build team, established construction costs prior to detailed design, open communication, and an efficient design and construction schedule that the firm claims averages 30% less time than the traditional design-bid-build process. Targeted at clients seeking fast-track schedules and aligned cost/schedule targets.
• General Contracting Traditional General Contracting (GC) delivery in which Rubicon prepares a competitive bid based on completed design and manages the complete construction process using an established team of prequalified subcontractor, labor, material, and equipment partners carefully matched to specific project needs, with day-to-day site oversight from construction documents through project completion. Targeted at commercial, institutional, healthcare, and public-sector projects where the design is complete and competitive bid pricing is appropriate.

• Columbia Construction Company: Northborough, MA-based full-service construction manager and general contractor of similar size serving academic, healthcare, senior living, corporate, and institutional clients across New England. Highly comparable in delivery models (CM, Design-Build, GC), regional footprint, and project scale.
• Lee Kennedy Company: Boston-based construction manager and general contractor serving commercial, institutional, healthcare, and academic clients throughout New England. Comparable in size, regional concentration, and service mix; competes for similar institutional and occupied-environment projects.

• Consigli Construction Co., Inc. Massachusetts-based construction manager and general contractor founded in 1905, serving institutional, academic, healthcare, and residential clients across New England.

Competes with Rubicon for institutional, healthcare, and academic work across New England but at much larger project sizes, with technology and self-perform capabilities beyond Rubicon's current scale.

Emerging players
