York City Sewer Authority – Digester No. 2 Roof Demolition & Assessment

Key Accomplishments

• The work was completed within an operating wastewater-treatment facility and required careful coordination with the York City Sewer Authority.
• JCC established the necessary work-area controls, access provisions, safety measures, and protective systems before beginning demolition.
• Demolition materials and construction debris were removed from the structure, handled safely, and disposed of in accordance with the project requirements.
• JCC coordinated the work with Buchart Horn, Inc. so the Engineer could observe and document the exposed structural conditions.
• Existing facility components designated to remain were protected throughout demolition and assessment activities.
• The work area was cleaned and secured following completion of the roof-removal and assessment operations.
• Johnston Construction Company served as the prime contractor for the Digester No. 2 Roof Demolition & Assessment project at the York City Sewer Authority facility in York, Pennsylvania.
• The project was performed at 1701 Blackridge Road and involved the controlled demolition of the existing roof associated with Digester No. 2, followed by exposure and assessment of the remaining structure.
• The York City Sewer Authority served as the Owner, Buchart Horn, Inc. served as the Engineer, and Johnston Construction Company served as the Contractor.
• Before demolition began, JCC coordinated its activities with the Owner and Engineer and reviewed the limits of work shown in the project documents.
• The company evaluated the required access to Digester No. 2, the surrounding operating facility, potential conflicts with existing structures and equipment, and the procedures necessary to safely perform the roof-removal work.
• Because the work occurred at an active wastewater-treatment facility, JCC had to complete the assigned demolition without unnecessarily interfering with the Owner’s continuing plant operations.
