J-2a ENA Appendices 012626.pdf

This document is an Appendix containing existing condition photographs, project location information, and an asbestos survey report for the refurbishment of the ENA (Enid Anna) Facility located at 505 N Willow Street, Kenai, Alaska 99611.

The existing condition photos document five envelopes of work required at the facility. Envelope 01 addresses the roof system, which requires replacement of patched roof materials, flashing, and roof drains, along with testing and replacement of a leaking roof hatch. Envelope 02 identifies rusted guard rails requiring rust treatment and repainting with marine-grade paint, as well as catwalk structure rust treatment and repainting of base and railing with marine-grade paint. Envelope 03 documents peeling paint and rusted panels on exterior surfaces requiring treatment and marine-grade paint application, and rusted panels at the building entrance requiring removal and replacement with design-match siding and insulation. Envelope 04 includes an emergency ladder requiring repainting or replacement if needed, and the ENA Air Traffic Control Tower (ATCT) requiring marine-grade sealant and paint application with color matching to existing materials where possible. Envelope 05 addresses tower cap joints and roof leaks penetrating building interiors.

The asbestos bulk sample analysis report, dated August 24, 2016, was conducted by WEC White Environmental Consultants on samples collected August 23, 2016 from the ENA Tower roof. Testing identified asbestos-containing materials in two of four samples analyzed: Sample ENA-0816-A02 from the southeast edge of the ATCT roof contained 10% chrysotile asbestos in tar mastic material (layer 1 of 2), and Sample ENA-0816-A02B from the same location contained 5% chrysotile asbestos in silver seal material (layer 2 of 2).
