Appeal Information Sheet

Appeal item 1

Code Section

Portland City Charter, Section 24.55.100; Demolition- Debris- Barricades- Nuisances; Paragraph IV

Requires

RECONSIDERATION TEXT (NO CHANGES FROM ORIGINAL APPEAL):
APPEAL #1: EXISTING BASEMENT AS TEMP SHORING
After removal of any structure, all foundations that are not to be used for new construction shall be removed and all excavations filled in compliance with Chapter 24.70 of this Title, to a level of the adjoining grade.

Code Modification or Alternate Requested

RECONSIDERATION TEXT (NO CHANGES FROM ORIGINAL APPEAL):
Leave a portion of the existing basement floor and walls in place for use as temporary shoring.

Proposed Design

See attached Exhibit TS1 – Shoring Plan and Basement Section for more information:
The proposed design indicates the extent of the existing basement walls and slab that will remain in place as temporary shoring during subgrade activities including demolition, excavation, and installation of structural piles.
Contractor (R&H Construction) will survey and document the location of existing basement walls when demolition begins, during subgrade activities, and then again when the area is backfilled. The GC will also confirm the thickness of the concrete wall and basement floor in addition to the reinforcing size and spacing. The Structural Engineer of Record (KPFF) to verify design assumptions. As-built record drawings will be maintained for the project file and can be submitted to the City if required.

RECONSIDERATION TEXT:
Drawing TS1 has been revised so it only includes Appeal #1

Reason for alternative

The existing building basement walls support the sidewalk and road along SW Alder and SW 17th. We are proposing to keep a portion of the basement walls, footings, and slab in place during construction to maintain the existing improvements in the public way. All of the existing elements that are proposed to remain in place are wholly contained on our property and do not project into the public right-of-way (ROW). These portions of the existing building will be abandoned in place when the new building is constructed.

KPFF has generated the proposed conceptual scheme based on as-built drawings from the existing building to support the existing walls and the sidewalk/road during construction. Prior to construction, the GC will verify the concrete wall thickness and reinforcing, and the conceptual design will be adjusted as needed.

Upon approval of this appeal, the Structural Engineer of Record will submit a revision to the building and demolition permits with final engineering drawings and calculations.
When construction begins the actual (conc thickness, rebar, etc) will be verified and design will be adjusted if needed- along with permit revision updates.

RECONSIDERATION TEXT:
We acknowledge that the following information will be submitted as a revision to the main permit 20-135027-CO if this appeal is approved:
• The demolition sheet will be amended in accordance with this appeal.
• The shoring sheet(s) will be added / amended in accordance with this appeal.
• Revised design calculations and geotechnical information will be included with permit revisions

Appeal Decision

Demolition of existing building with existing basement floor and walls to remain in place for use as temporary shoring: Granted as proposed.

The Administrative Appeal Board finds that the information submitted by the appellant demonstrates that the approved modifications or alternate methods are consistent with the intent of the code; do not lessen health, safety, accessibility, life, fire safety or structural requirements; and that special conditions unique to this project make strict application of those code sections impractical.
