Cranbrook Alumni Court: Phase 1 Ends, Phase 2 Begins!

In my previous post related to the Alumni Court restoration project, we had recently finished the masonry restoration of the vertical walls and were preparing the upper level walkway for concrete installation.  Now, it is safe to say Phase 1 has been completed and is looking just as beautiful as when the courtyard was originally constructed in 1927.

Over the past 6 months, we have been busy finishing up Phase 1 and completing activities such as: pouring the upper level concrete walkway; installing all flat paving (including brick, fieldstone, and red slate); and replacing limestone columns and bases. We also restored three windows and the interior plaster work damaged by water infiltrating the building over the years.

It was very exciting to see how the contractor replaced the columns and their bases. Before any demolition could begin, the brick arches were supported by heavy duty scaffolding with an I-beam and custom-made wooden forms fitted directly into each arch. With this configuration, the contractor was able to ever-so-slightly raise each arch so that there was enough room to remove the column capitals, the columns, and finally the column bases.  At that point, the new bases could be installed, followed by new columns, and the existing column capitals.

Throughout the Spring, we will be continuing with Phase 2 which includes restoring the upper level walkway running north/south, columns/arches running north/south, paving work directly below the walkway, and the remaining paving within the courtyard.

Stay tuned for a progress report on Phase 2. As always, many thanks to the contractors and architects who work so hard on these projects.

Editor’s Note: The four new columns have the alumni names carved into them, and the originals (which had severely degraded and were illegible) will be stored safely elsewhere on campus.

Alumni Court: Restoration Update

The first phase of restoration of the Cranbrook Alumni Court commenced on Wednesday, April 26, 2017. This area, on the far western edge of the original Cranbrook School for Boys campus, contains many beautiful carvings commemorating graduating classes of Cranbrook seniors arranged around a lawn. Phase 1 of the restoration includes rebuilding the upper level walkway running east to west, relaying the paving on the courtyard interior, and restoring the columns, arches, and wall running east to west.  (Future phases include the upper level walkway, columns, and arches running north to south, the masonry stairs aside the courtyard, and all flat paving to the football oval.)

Over the years, salt and water infiltration caused major deterioration of the Alumni Court’s paving, walls, and walkways. One of the most important improvements we added to this project is heating the walkways.  Heating minimizes the resources needed to constantly shovel and spread ice melt, preserving the materials.

The project’s contractor began with demolition of all material that was beyond repair–mostly the flat areas and the setting beds below.IMG_2343Once the demolition was complete, the contractor replaced the underground storm drain, which was originally clay piping, with new PVC piping. Clay piping is brittle and therefore susceptible to intruding tree roots which lead to leaks and clogs.  The PVC piping will last much longer and minimize maintenance work. Once the PVC piping was installed, soil was filled in and compacted and the trenches were capped with concrete. IMG_2378The next activity was demolishing the concrete bridge. All the existing limestone newel posts and railings were in good condition, so they were set aside to be reinstalled. The masonry wall, below the bridge, was also disassembled because many of the bricks were extremely fragile and showed efflorescence.IMG_2599After a summer of careful work, the masonry wall and arches have been rebuilt to their original beauty.  IMG_0159The concrete bridge has been layered with waterproofing, reinforcing, and heating pipes, and is ready to be poured back with concrete.  The flat paving areas are being prepared for their final layer of brick and stone. IMG_0188Look forward to a final update here on the Blog once the project is complete! As always, many thanks to the contractors who are working hard on this beautiful restoration.
