When Stone & Glazing Consulting (SGC) of Dallas, TX, called on Bob Zeolla of American Anchor (AA) in Boston with a unique access problem, Bob jumped on a plane to investigate the situation. What he found was a rotunda building with a capitol-style dome that was leaking in 100 locations.
Every joint of the dome needed to be cleaned out and replaced – that was the easy
part. The hard part – providing access so the work could be done. Recalls SGC’s
Mark Mathson, “How would we safely get a team up on the top and sides of the
dome?” Mark knew that easy and quick access for a crew meant a better project
in terms of costs and results for his client, the building owner.
Bob went back to Boston with an armful of drawings and a sketch on a napkin to
show his team. After multiple meetings and some awesome work by AA’s design and
engineering group, they had a plan. Now the manufacturing team at AA’s facility in
Pennsylvania had to build a custom ladder to match the engineers’ design specs.
They came through with a ladder and anchor system that matched the building’s
arch exactly. One of the unique details of the ladder is that it has flat rungs along the

entire arch, creating solid footing all the way to the top. When the crane started to
drop the pieces into place, they fit like a glove. Special anchor bolts purchased in the
Netherlands secured the ladder and AA’s installation team made it all look easy. Team
members made the initial attachments while hanging in harnesses from a crane.
With a color-matched ladder to the peak of the dome, workers can now climb up the
dome, secure working lines to one of the fall arrest anchors installed at the top, and
rappel down to any area that needs service. It will make the waterproofing project
efficient and safe as well as any future maintenance that the dome requires.
The team at American Anchors enjoyed the challenge of creating a solution that
solved a dilemma for the client.
