Platinum Structural Steel — structural steel and steel beam installation

Market

Historic & Brownstone Retrofit

Structural steel inside Back Bay, South End and mill buildings, to approved historic details.

Back Bay, Beacon Hill, the South End and Charlestown are full of buildings whose structure is 120 years old, whose lintels are corroding, and whose facades are under commission review.

Steel work in these buildings is slow, careful and mostly done by hand. We plan it that way instead of pretending it is new construction.

Typical scopes

  • Corroded lintel replacement over brownstone and brick openings
  • Basement and parlor-level beam replacement in row houses
  • Structural reinforcement for new stairs, elevators and roof decks
  • Mill building adaptive reuse framing
  • Facade and bay window support steel

Project planning

Conditions we plan around

No crane, no laydown, no room

Steel typically arrives in sections that fit through a doorway or a window and gets welded together in place. That is a rigging and field-welding problem before it is an erection problem.

Commission and landmark review

Boston Landmarks Commission and neighborhood architectural commissions govern anything visible. Details get approved before fabrication, and we install to what was approved.

Unknown existing conditions

Every one of these buildings has been modified several times. We investigate before we price wherever the owner will allow it, because the difference between assumed and actual conditions in a 1890s row house is large.
