Commercial General Contractors in Boston, MA & Southern NH

The commercial general contracting market in Greater Boston is crowded. What separates firms is not whether they can manage subcontractors and pull permits. Every licensed GC can do that. What separates them is whether senior leadership stays engaged throughout the project, whether cost commitments hold from pre-construction through closeout, and whether the firm has the specific sector experience your project requires. Avatar Design and Construction has operated as a primary commercial general contractor across Boston, Greater Boston, and Southern New Hampshire since 1999. We back every project with a Guaranteed Maximum Price and with direct senior involvement from the first planning conversation to the final certificate of occupancy.

Commercial General Contracting Services

Avatar’s general contracting scope covers the full lifecycle of a commercial construction project:

  • Pre-Construction Planning and Budgeting
  • Subcontractor Bidding, Selection, and Management
  • Cost Control and Value Engineering
  • Schedule Development and Management
  • Procurement and Material Management
  • Site Supervision and Safety Program Management
  • Construction Document Management
  • Change Order Management
  • Permitting and Regulatory Coordination
  • Quality Control and Inspections
  • Owner Reporting and Communication
  • Project Closeout and Warranty Management

General contracting at Avatar is not a standalone service. It runs alongside our design-build and construction management capabilities, which means if your project scope changes during delivery, we have the internal resources to adapt without bringing in outside firms.

Project Types and Sectors We Serve as GC

Avatar’s commercial general contracting experience spans multiple sectors. The project types we actively pursue and have deep delivery experience in include:

Multi-Family and Mixed-Use Developments

Ground-up apartment buildings, urban infill multi-unit construction, and mixed-use retail-residential developments across Greater Boston and Southern NH. Projects ranging from 6 units to 100+ units in both new construction and adaptive reuse.

Healthcare and Medical Facilities

Community health centers, behavioral health facilities, urgent care centers, medical office buildings, and day habilitation programs. Healthcare construction carries licensing, regulatory, and clinical workflow requirements that most general contractors are not equipped to manage. Avatar has delivered these projects through to DPH licensure.

Commercial and Institutional Buildings

Office buildings, laboratory and research facilities, warehouse and industrial builds, and institutional projects including municipal and educational facilities across Massachusetts and New Hampshire.

Renovation and Repositioning

Major commercial renovations, building repositioning projects, historical restorations, and occupied-facility upgrades where phased construction and operational continuity are non-negotiable.

What Separates Avatar as a Commercial General Contractor in Boston

There is no shortage of licensed general contractors in Greater Boston willing to bid your project. The differentiators that matter at the project level are specific.

Guaranteed Maximum Price

Most general contractors operate on either a lump sum bid or a cost-plus structure. Lump sum bids win projects and then recover margin through change orders. Cost-plus leaves budget exposure on the owner. Avatar’s GMP model establishes a firm cost ceiling before construction begins. Your maximum is locked. That structure changes the entire incentive dynamic of a construction contract.

Pre-Construction Depth

The cost decisions that determine whether a project succeeds financially are made before a shovel goes in the ground. Avatar’s pre-construction services include full budget development, value engineering, subcontractor pre-qualification, schedule development, and constructability analysis before construction documents are finalized. Projects that skip this step typically pay for it in change orders.

Senior Management Accessibility

On every Avatar project, the principals who set the project plan are directly involved throughout construction. Owners and developers working on projects in the $5 million to $25 million range should not have to escalate through a junior project manager to get a decision made or a problem resolved. At Avatar, that access is not a premium feature. It is how the firm operates.

Subcontractor Relationships Built Over 25 Years

The subcontractor network Avatar has developed across Greater Boston and Southern NH over 25 years of commercial work translates directly to schedule reliability, pricing leverage, and accountability on site. Subcontractors perform differently under a GC they have a track record with. That relationship dynamic affects your project whether you see it or not.

Single-Source Accountability

As both a design-builder and a general contractor, Avatar can carry projects that start with a program and a site all the way through construction without the owner managing a chain of separate design and construction contracts. When scope, schedule, or design issues arise, there is one firm accountable for resolution.

Frequently Asked Questions About Our General Contracting Services

A traditional general contractor is typically hired after design is finalized, managing construction against someone else’s drawings.

    I’ve partnered with Avatar Design and Construction for almost a decade on a range of commercial projects — multifamily housing, medical offices, daycare facilities, and warehouses. They excel in design-build delivery and consistently manage risk and cost through a well-run Guaranteed Maximum Price model. Throughout our relationship they’ve demonstrated outstanding project management, clear communication, and practical problem-solving on complex schedules and tight budgets. Their workmanship and attention to detail are top-notch, and I’ve watched the firm grow exponentially while maintaining high standards. If you need a trusted design-build partner who delivers on time and on budget, I strongly recommend Avatar Design and Construction

    After we had some plumbing issues occur just outside the 1 year warranty of our new construction home, Avatar helped us resolve the areas of concern. We were happy with the work completed and the assistance we received. The project manager we worked with, Liu, was very helpful, responsive, and pleasant to work with. We were very happy with Liu's communication and impressed with the seamlessness of the repair work completed.

    We purchased a home that had been built by Avatar Construction, and after discovering some issues post-purchase, we needed warranty work done. Liu was assigned as our project manager, and he was a pleasure to work with. Liu was consistently responsive, professional, and took pride in his work. He coordinated handymen who delivered high-quality repair finish work, and helped us coordinate with third parties. He made a point of personally showing up to supervise each job, which felt nice and reassuring. It's good to know Avatar Construction sent someone like Liu to make things right.
