EOS 90395-A-PHY-0002-Column feet assembly & setting

h. On the the primary side,
proceed to drill each of the

identified holes using an 18mm
drill bit to a pre-determined
depth.

IMPORTANT - Keep in mind that some old versions Nivell plates may require a
2-step drilling process due to hole diameter limitations. In such case, you may
have to drill a smaller diameter hole before ending with the required 18mm.
IMPORTANT - the drilling depth may change from site to site based on the

existing characteristics of the concrete slab. EOS requires a minimum depth of
100mm.

i. Drill holes using the proper equipment and use a spotter to assist you. You want to make sure
your drilling is as straight as possible. Mark the drill bit to indicate the proper depth while
taking into consideration the height of the Nivell and the height of any extra shim added.
Anchor blots of 140 - 150mm in length would probably suffice.

j. Take your time with each hole and try not to push down too hard on the hammer drill. Use a
good drill and new drill bits and let the drill do the work for you.

k. Use a vacuum cleaner to collect the dust produced during the drilling process.

l. Once all holes are drilled, re-check crossbar levelness and position on both sides to make
sure nothing changed drastically during the drilling process.
