Earlier versions of the newsletters will be made available upon request. In addition to the newsletters, there will be weekly tenant updates via a 15-minute GoTo meeting hosted by SEH. The next one will be held Tuesday, June 4th, at 12:30PM. The log in and call information can be obtained at the end of this newsletter.
Runway 9/27 Construction Progress
With the beautiful weather this week, the contractor was able to make good progress on Phase 3A work items. The week started with final grading and compaction on the existing subgrade, as well as the installation of the Taxiway A in-pavement centerline light electrical conduit. Items installed later in the week included geotextile fabric, aggregate base, as well as drainage structures and pipe near the new Taxiway A5 location. Aggregate base will continue to be installed, compacted, and tested heading into the weekend.
