MATERIAL SPECIFICATIONS

HEAVY TIMBER CONSTRUCTION

1. DESIGN AND CONSTRUCT THE HEAVY TIMBER FRAME AND ALL FRAME TO FRAME

CONNECTIONS IN ACCORDANCE WITH THE LATEST EDITION OF AF&PA NATIONAL

DESIGN SPECIFICATION (NDS) AND TIMBER FRAME ENGINEERING COUNCIL (TFEC)

STANDARD FOR DESIGN OF TIMBER FRAME STRUCTURES 1-2019.

2. THE TIMBER FRAME, AS DETAILED IN THESE DOCUMENTS, IS DESIGNED TO PROVIDE

RESISTANCE TO LATERAL LOADS AFTER COMPLETION OF THE STRUCTURE. IT IS THE

RESPONSIBILITY OF THE ERECTOR OF THE TIMBER SYSTEM TO PROVIDE AND

MAINTAIN ANY REQUIRED TEMPORARY SUPPORT OF THE HEAVY TIMBER SYSTEM

UNTIL ERECTION IS COMPLETE.

3. UNLESS NOTED OTHERWISE, HEAVY TIMBER MATERIAL SHALL BE DOUGLAS

FIR-LARCH, NO. 1 AND BETTER, 19% MAX. MOISTURE CONTENT, FREE OF HEART

CENTER.

4. TIMBER MEMBER SIZES NOTED IN THE DRAWINGS ARE CALLED OUT AS ACTUAL SIZES.

SIZES NOTED ARE MINIMUM, AND TIMBER FRAME FABRICATOR MAY SUBSTITUTE

LARGER TIMBERS AS REQUIRED.

5. THE TIMBER FRAME MANUFACTURER/SUPPLIER SHALL BE SOLELY RESPONSIBLE FOR

THE DESIGN OF ALL TIMBER FRAME JOINTS AND CONNECTIONS AS REQUIRED TO

TRANSFER APPLICABLE DEAD AND LIVE LOADS. THE FOLLOWING REQUIREMENTS

SHALL APPLY TO DESIGN OF THE TIMBER FRAME CONNECTIONS:

A. A. SCREWS, WHERE REQUIRED SHALL BE TIMBERLOK BY FASTENMASTER, OR

RSS BY GRK. SCREWS SHALL PENETRATE A MINIMUM OF 3" INTO RECEIVING

TIMBER. WHERE HEADS WOULD BE EXPOSED FROM THE INTERIOR OF THE

COMPLETED STRUCTURE, INSTALL IN COUNTER-BORED HOLES AND PLUG

B. PEGS SHALL BE MINIMUM 1" THICK DIAMETER, STRAIGHT-GRAINED OAK,

TREATED WITH PARAFFIN, LINSEED OIL OR SIMILAR SEALING SUBSTANCE.

C. FULL TENONS: 2" THICK BY 4" LONG WITH 1" HOUSING (UNLESS OTHERWISE

NOTED OR SHORTENED TO ACCOMMODATE TIMBER SIZE)

D. THREADED ROD SHALL BE HOT-DIPPED GALVANIZED ASTM A307 GRADE B

E. POST BASES AND ANCHORS: SIMPSON CPS10 STANDOFF BASE WITH 5 8"Ø x 16"

THREADED ROD ANCHOR. EPOXY ANCHOR INTO CONCRETE WITH 6"

EMBEDMENT (MIN) AND INTO POST WITH 10" EMBEDMENT USING SIMPSON

SET-3G OR EQUAL.

TONGUE AND GROOVE (T&G) HEAVY TIMBER ROOF DECKING

1. ROOF DECKING SHALL BE VISUALLY GRADED AND STAMPED PER WCLIB OR WWPA

GRADING RULES. MOISTURE CONTENT OF SHALL BE 15% MAXIMUM.

2. ROOF DECKING SHALL 2x6 NOMINAL DOUGLAS FIR-LARCH, "SELECT DEX" OR "SELECT

DECKING" GRADE, U.N.O

3. INSTALL ROOF DECKING IN SPAN CONDITIONS SHOWN IN DRAWINGS. EACH PIECE

SHALL BE SQUARE-END TRIM.

4. INSTALL DECKING WITH TONGUE UP ON SLOPED OR PITCHED ROOFS, AND WITH

PATTERN FACE DOWN AND EXPOSED ON THE UNDERSIDE.

5. EACH PIECE SHALL BE TOENAILED THROUGH THE TONGUE AND FACE NAILED WITH

ONE NAIL PER SUPPORT, USING 16d COMMON NAILS.

WOOD STRUCTURAL PANELS

1. STRUCTURAL PANELS SHALL CONFORM TO PRODUCT STANDARD PS-1 AND BEAR THE

TRADEMARK OF AN APPROVED TESTING AND GRADING AGENCY.

2. PROVIDE WOOD STRUCTURAL PANELS COMPLYING WITH THE FOLLOWING:

-19

32" RATED SHEATHING

-EXPOSURE 1

-NAIL WITH 6d COMMON NAILS @ 6" O.C. AT PANEL EDGES AND @ 12" O.C. IN THE

FIELD OF THE PANEL, U.N.O.
