description_raw: City Funded Emergency Demolition 
  1.EMERGENCY DEMOLITION. Remove all garbage and debris, vegetation, fencing, concrete slabs, and steps. 
  2.Contract term: 48 HRS. 
  3.Remaining void to be filled to engineer’s specs.
  4.ACHD asbestos application is required.
  5.Coordinate demolition with utility companies operating overhead utilities along Arlington Avenue at the base of the slope. The utilities may have to be temporarily relocated or de-energized/disconnected during the demolition due to their proximity to the structure.
  6.Incorporate provisions to protect the roadway and Light Rail tracks in the roadway from construction equipment traffic and debris and clean up/repair the roadway and tracks upon completion of the work. Requirements for protection of the track and roadway should be coordinated with the Port Authority and DOMI, respectively.
  7. Place a traffic barrier along the uphill side of the Arlington Avenue sidewalk and a 12-inch filter sock along the back side of the barrier as shown on the attached plan and cross-section after the structure has been removed. The intent of the barrier is to prevent any loose granular fill material from encroaching on the roadway or sidewalk. Also place inlet filter bags in nearby storm system drop inlets. Incorporate other sediment control measures based on Best Practices consistent with Allegheny County Conservation District (ACCD) and Pennsylvania Department of Environmental Protection (PADEP) guidelines/requirements as needed.
  8. A portion of the detour signage responsibility will be deferred to the demolition contractor.
  9.Disconnect and cap all utility service lines if they are not already disconnected
  10.Demolish and remove/dispose of the structure located at 322/324 Arlington Avenue, to the basement floor level and break up the floor from the Arlington Avenue sidewalk to a distance of 8 feet from the lower rear basement wall consistent with PLI requirements, being sure to plug any remaining floor drains with concrete. The floor within 8 feet of the rear basement wall should remain intact as this floor section may be proving support for the lower and upper level rear walls prior to basement backfilling. Demolish foundation walls to one (1) foot below finished grade, with the exception of the rear wall(s) which shall remain in place. Provide temporary support for the rear basement wall(s) during demolition by placing AASHTO No. 1 coarse aggregate prior to fully demolishing any supporting foundation walls or structures as shown on the typical section or by other methods approved by PLI throughout the demolition work and protect and support adjacent facilities/structures as required. If necessary, the shell of the should be demolished and AASHTO No. 1 coarse aggregate placed incrementally as the structure is removed around the placed material.
  11.	Place AASHTO No.1 aggregate backfill within the footprint of the demolished structure and against the adjacent hillsides as shown on the plan up to the existing grade behind the structure to create a finished slope having a final grade of 1.5 horizontal to 1 vertical or flatter that conforms to the adjacent natural ground surface topography.
  12.Demobilize and remove E&S controls as indicated on the plan.
  13.D’Appolonia will visit the site during and following structure demolition to recommend modification of the slope regrading, as warranted.
  14.Schedule and logistics to remain flexible until safety concerns are addressed.
