225 Bush Street

Scope/Solutions

Constructed in 1922 with a major addition in 1950, the twenty-two-story building at 225 Bush Street is located in the central downtown business district. The building formerly housed the Standard Oil Corporation headquarters and is listed as a local historic landmark. Jones Lang LaSalle retained SGH to develop a rehabilitation program for the exterior walls and roofs.

SGH performed a condition assessment of the terra cotta and brick walls and clay tile roofs using rope access and also conducted an archival search that produced original terra cotta shop drawings.

We developed repair options and prepared construction documents for the rehabilitation. The historic nature of the building required a familiarity with local regulatory requirements for historic buildings and our proposed repairs were carefully evaluated by local preservation planning officials for project approval.

SGH collaborated with the owner to phase the project to accommodate their budget and funding cycles, and to minimize the potential disruption to tenants. Our rehabilitation design included facade repairs (replacing the terra cotta cornices, soffits, lintels, and ashlar blocks) and repairs to the hipped clay tile roof (new underlayment, copper flashing, and gutters).
