1 - FOR INSTALLATION STABILITY, Temporary strut lines - (1x4 min.) 8" on center max. Fasten at each joist with two 8d nails min.
2 - VERSA-LAM LVL support beam
3 - BCI joist blocking or metal or wood X-bracing for lateral support.
4 - BCI joist header.
5 - Multiple BCI joists may be required.

Roof Notes

NAILING OF SHEATHING TO TOP FLANGE

• See closest allowable nail spacing information.
• Maximum spacing of nails is 18" o.c. for BCI 40s Series and BCI 45s Series joists, and 24" o.c. for BCI 60s Series joists. If more than one row of nails is used, the rows must be offset at least 1/2". 14-gauge staples may be substituted for 8d nails if the staples penetrate the BCI joist at least 1".

SAFETY WARNINGS
SERIOUS ACCIDENTS CAN RESULT FROM INSUFFICIENT ATTENTION TO PROPER BRACING DURING CONSTRUCTION. ACCIDENTS CAN BE AVOIDED UNDER NORMAL CONDITIONS BY FOLLOWING THESE GUIDELINES:

DO NOT ALLOW WORKERS ON BCI JOISTS UNTIL ALL BLOCKING, HANGERS, RIM JOISTS AND TEMPORARY BRACING ARE COMPLETED AS SPECIFIED IN ITEMS A THROUGH C.

1. A lateral support, such as an existing deck or a braced end wall must be established at the ends of the bay. Alternatively, a temporary or permanent deck (sheathing) may be nailed to the first 4' of joists at the end of the bay.
2. All hangers, blocking, X-Bracing and rim joists at the end supports of the BCI joists must be completely installed and properly nailed.
3. Temporary strut lines of at least 1x4 must be nailed to the sheathed area or braced end wall as in item A above and to each joist at no more than 8' o.c. Otherwise, buckling sideways or roll over is likely under light construction loads.
4. Sheathing must be completely attached to BCI joist before removing temporary strut lines.
5. The ends of cantilevers must be temporarily secured by strut lines on both the bottom and top flanges.
6. The top flanges must be kept straight within 1/2" of true alignment.
