SAFETY WARNING
DO NOT ALLOW WORKERS ON BCI® JOISTS UNTIL ALL
HANGERS, BCI® RIM JOISTS, RIM BOARDS, BCI® BLOCKING
PANELS, X-BRACING AND TEMPORARY 1x4 STRUT LINES ARE
INSTALLED AS SPECIFIED BELOW. SERIOUS ACCIDENTS
CAN RESULT FROM INSUFFICIENT ATTENTION TO PROPER
BRACING DURING CONSTRUCTION. ACCIDENTS CAN BE
AVOIDED UNDER NORMAL CONDITIONS BY FOLLOWING
THESE GUIDELINES:
• Build a braced end wall at the end of the bay, or permanently
install the first eight feet of BCI® Joists and the first course of
sheathing. As an alternate, temporary sheathing may be nailed to
the first four feet of BCI® Joists at the end of the bay.
• All hangers, BCI® rim joists, rim boards, BCI® blocking panels, and
x-bracing must be completely installed and properly nailed as each
BCI® Joist is set.
• Install temporary 1x4 strut lines at no more than eight feet on
center as additional BCI® Joists are set. Nail the strut lines to the
sheathed area, or braced end wall, and to each BCI® Joist with two
8d nails.
• The ends of cantilevers must be temporarily secured by strut lines
on both the top and bottom flanges.
• Straighten the BCI® Joists to within 1/2 inch of true alignment
before attaching strut lines and sheathing.
• Remove the temporary strut lines only as required to install the
permanent sheathing.
• Failure to install temporary bracing may result in sideways buckling
or roll-over under light construction loads.
• Do not stack construction materials (sheathing, drywall, etc)
in the middle of BCI Joist spans, contact Boise Cascade EWP
Engineering for proper storage and shoring information.

VERSA-LAM® Products

An Introduction to VERSA-LAM® Products

When you specify VERSA-LAM® laminated veneer
headers/beams, you are building quality into your
design. They are excel­lent as floor and roof framing
supports or as headers for doors, windows and garage
doors and columns.

Because they have no camber, VERSA-LAM®

LVL products provide flatter, quieter floors, and
consequently, the builder can expect happier
customers with significantly fewer call backs.
