GENERAL NOTES NOTES ON USAGE

1. Use tower details, truss details, truss to tower connection, and foundation 1. This sheet shall only be included in the PS&E package when the OVERHEAD SIGN details, shown on standard drawings OSBT, OSBC, COSSD, and COSSF. COSS and/or OSB standards are not sufficient to define the COSS or OSB design and details. BRIDGE DETAILS 2. Dimensions and connections, should be determined, using member size or combination of members shown on this sheet. 2. These sheets should not be included in the PS&E package if no design data is included hereon. 3. Number of high strength bolts required in truss connection or splice are indicated in brackets, e.g. [3], after the member size. 3. If included in the contract plans this sheet must contain "(MOD)" COSS & OSB-SZ-21 after the designation and must be sealed by a Texas P.E. FILE: coss-osb-sz-21.dgn DN: CK: DW: CK: 4.
