17 May Opus 40 Phase 1 Week 4
Rebuilding continues
The Opus 40 restoration returned for week three, again with a crew of 7 wallers. Building on last weeks experiance, walling continued at a fast pace. As the wall heights increased staging setups were continually modified so the work could be done at a convenient height. This weeks crew was: Brian Post, Michael Weitzner, Bryce Hollingsworth, Ben Maron, TJ Mora, Victoria Merriman and Sean Kelly.
The Entrance Ramp Wall
The Entrance Ramp Wall
The northeast side of the entrance ramp wall has now transistioned to working on the drainage and top surface. About 12″ from the top surface an EPDM rubber membrane was laid in to catch all rain and melt water and direct it to a newly installed drain pipe. This will prevent a large volume of water from entering the understructure of the ramp and reduce further deterioration of the stone as well as outward pressure from freezing water. As the week progressed several capstones were laid. TJ Mora and Bryce Hollingsworth led the work with help from Sean, and Seth. Brian focused on the EPDM installation.
