A key requirement in preserving historic structures is STRUCTURAL RETROFITTING, which presents with it some unique challenges. Specializing in historic preservation construction and working closely with structural engineering experts, Spectra Company has the experience to identify potential retrofit alternatives early on, with a focus on mitigating any possible impact the retrofit may have on the historic character of the structure. Seismic retrofit methods used by Spectra Company include steel moment and braced frames, concrete shear walls, shotcrete, underpinning, wood framing anchors, and shear panels.
