Oakland Cemetery’s Beaumont Allen Greenhouse is located between the historic boiler room and carriage house structure near the cemetery’s northern boundary. These buildings were constructed around the turn of the 20th century and aided facility and lot management at Oakland as the cemetery continued to grow. The original greenhouse has since been removed, but the structure’s supporting walls remain. These walls may not support a greenhouse anymore, but they do support the cemetery’s historic integrity and serve as a symbol of our earliest efforts to make Oakland beautiful.
Since the past repairs, the Beaumont Allen Greenhouse wall was retaining excessive amounts of water and allowed for many weak spots in the structure to develop and worsen to critical condition in recent months. The top of the wall had cracked, separated, and created a hazard for those walking near it.
This May a structural engineer with architectural firm Wiley|Wilson discussed with the PRO Team the Beaumont Allen Greenhouse’s east wall. The engineer addressed possible solutions to save the wall from collapsing. A feasible solution included: removing the cement cap atop the structure, repointing with an appropriate mortar, and inserting steel stitch rods into the wall to re-tie it.
Following the advice of the structural engineer, appropriate repairs have been made to the wall over the past two months, and the work is nearing completion.
Steel stitch rods were embedded every forth course of bricks to add stability to the structure.
The remains of the crumbling cement cap were chiseled off and are being recreated with a buff-colored lime mortar cap using the same mortar mixture the wall has been appropriately repointed with. With the wall’s repairs coming to an end, a final brace will be added in coming weeks to adjoin the wall to the carriage structure to ensure the wall’s longevity.
