Platinum Structural Steel — structural steel and steel beam installation

Service area

Structural steel in Somerville, Massachusetts

Triple-deckers, condo conversions and Union/Assembly Square development.

Somerville is the densest city in New England and it is built almost entirely out of triple-deckers, most of which are being converted to condos one at a time.

That produces a very specific steel market: basement girders, lally columns, first-floor beams for open plans, and new stair and deck framing, all on lots with three feet between buildings.

Permitting and access

Somerville Inspectional Services requires a permit and stamped structural drawings for load path changes. The practical constraint in Somerville is not the permit, it is the street: crane setups, material delivery and even a boom truck usually require a street occupancy permit and neighbor coordination, and many blocks simply cannot host a crane. We plan most Somerville residential work as hand-rigged or sectioned steel for that reason.

Typical local scopes

  • Basement girder replacement with new columns and footings
  • First-floor beams for open kitchen and living renovations
  • Load-bearing wall removal in unit-by-unit condo conversions
  • Deck, stair and porch structural steel
  • Podium and stair steel on Union and Assembly Square projects

Local conditions

Building stock we encounter

Triple-decker conversions

Full-gut condo conversions where each unit gets an open kitchen, which means a beam per floor and a column line carried down to a new footing in the basement.

Basement girders and columns

Original girders that have taken a permanent set, on lally columns sitting on the slab with no footing. Replacing both together is the standard scope here.

Union Square and Assembly Row development

New mixed-use and multifamily construction with podium steel, transfer framing and egress stair packages.
