Exterior Stairway Repair

Exterior Stairway Repair

Repair and replace deteriorated exterior elements of the 1881 Heilbron Mansion at the corner of 7th and O Streets in Sacramento, which is listed on the National Register of Historic Places. Project includes removing and replacing the front stairs/railing/balcony of the north entry, replacing the east stairway, and replacing the west side balcony. As identified in the 2003 Heilbron Historic Structure Report section on "Porticos," these defined areas have rotted and deteriorated to the point of being an extreme safety concern and must be dealth with as soon as possible. Project mainly entails the removal of only non-historic fabric. Original fabric will be replaced only if it is rotted beyond repair. In cases where the original fabric is salvageable, the project manager agrees to use epoxies and/or "Dutchmen" and scarf joints in order to repair and re-use original decorative and structural elements. Project is approved upon the conditions that all balusters and original handrails will be repaired and re-used in their original locations. Non-original handrails will be replaced with examples that match historic photographs or surviving originals. Decorative trim will be re-used unless it is rotted beyond repair. Structural members will be repaired and re-used unless rotted beyond repair. Project manager shall ensure use of scarf joints, stitch plates, and sister joists in order to save as much original fabric as possible. State Historian must be notified if DCU encounters major structural elements that are rotten and in need of replacement. DPR-qualified historian must be present for start-up meeting and at the beginning of work on the project. The north and east exterior stairs shall incorporate accessibility requirements for handrails, rail configuration, rail extensions, tread design and nosing design per sections 1133B.4 through 1133B.4.3.5 of the California Building Code. Project manager shall make arrangements with the DPR Accessibility Section to document, verify and inspect the work in progress with the use of Construction Verified Reports Forms. This method of construction verification will be sufficient to certify the project for ADA compliance in lieu of providing certified construction drawings prepared by a state-licensed designer.
