stood in the corner of the little park for quite a while
before any visible activity took place. A lot was happening
though. There was design work and fundraising to do,
materials to purchase and numerous other activities in
preparation for construction.
Burnett and I spent many hours surveying the site. There were
many parameters that had to be established. Where was true
north? The exact position of all the sundial components had to
be established and marked as the project progressed. Surveying
was a huge undertaking and we we extremely fortunate to have
Barrie helping with the project.
first job was to remove all the organic material from the
sundial site to expose the clay beneath.
Batter boards were
set to position the four piles at the correct locations and
pile would be 16 in. in diameter and 16 ft. deep. Cages were
constructed that would support the gnomon. A cage consists of
4-1 in. threaded rods 10 ft. long welded to 20M rebar for a
minimum distance of 36 inches. The rebar extends down the
length of the pile. 10-10 in. diameter 10M rebar rings are
spaced along the length of each cage.
