How to install Berntsen Survey Markers

Tools: Berntsen suggests these tools to help with your installation.

• Dead-Blow Hammer (Lixie Hammer)
• Rebar Driver 
• Vice-Grip Pliers
• Felt-tip Permanent Marker

Pre-Installation: Save time in the field with a little preparation in your shop.

• Cut your rebar to your desired length using a hacksaw or power press.
• Remove any burrs and/or mushrooming on the end that will be receiving the survey marker
• For maximum grip, bevel the end of the rebar that will be receiving the survey marker

Installing the Rebar:
With a felt-tip permanent marker, place a mark about 1½" from the end of the rebar.  This mark will be your guide to assure the cap is tightly and completely seated on the rebar.

Drive your rebar to the desired depth.  Remember to leave enough rebar to install the survey marker.

Installing the Survey Marker:
To restrict any "sinking" of the rebar into the ground when applying the survey marker, clamp a vice-grip pliers to the rebar at ground level.  The handle of the pliers will prevent the rebar from sinking into the soil as you drive on the survey cap.

Some surveyors pre-install the survey marker onto the rebar prior to entering the field and then drive the rebar and marker assembly with a dead-blow hammer.

Once you have your rebar and cap to the desired depth your installation is complete.
