b. For nominal sizes up to 2” thick and wider than 4”: #2 and better.

PART 3 - EXECUTION

3.1 PREPARATION

Herbert, Rowland & Grubic, Inc. 06 10 00 - 3 000483.0450

A. Verify measurements, dimensions, and shop drawing details before proceeding.

B. Coordinate location of furring, nailers, blocking, grounds and similar supports for attached work.

C. Eliminate sharp projections which would puncture roofing, flashing or underlayment material.

3.2 ERECTION AND INSTALLATION

A. General:

1. Provide treated material in accordance with appropriate AWPA standard for intended end use.

2. Provide preservative treated material for all wood used:

a. Outside building.

b. Below grade.

3. Field treat cuts and holes in preservative and fire-retardant treated material in accordance with AWPA M4.

B. Attach work securely by anchoring and fastening as indicated or required to support applied loading.

1. Provide washers under bolt heads and nuts.

2. Fasten plywood in accordance with APA recommendations.

3. Use hot-dipped galvanized steel for high humidity and treated wood locations, unfinished steel elsewhere.

4. Use common wire nails or screws for general work.

5. Use fasteners of size that will not penetrate members where opposite side will be exposed to view or receive finish materials.

6. Install fasteners without splitting of wood; predrill as required.

7. Do not drive threaded friction type fasteners.

8. Tighten bolts and lag screws at installation and retighten as required.

C. Set work to required levels and Iines, plumb, true.

1. Shim as required.

2. Cut and fit accurately.

D. Provide wood grounds, nailers, or blocking where required for attachment of other work and surface applied items. Form to shapes indicated or required

1. Grounds:

a. Dressed, key beveled lumber minimum 1-1/2” wide of thickness required to bring face of ground even with finish material.

b. Remove temporary grounds when no longer required.

2. Install roofing nailers as indicated:

a. Install per roofing manufacturer's recommendations.

b. Match height of nailers to insulation.

c. Anchor nailers to resist force of 75 PLF.

d. Use minimum of three anchors for each nailer with ½” vent spaces

Herbert, Rowland & Grubic, Inc. 06 10 00 - 4 000483.0450 between Iengths of nailers.

e. Install nailers over vapor retarder where indicated.

E. Install wood furring plumb and level with closure strips at all edges and openings.

F. When wood has been exposed to moisture allow to completely dry out prior to covering with additional wood or another material.

G. Correct or replace wood which shows bowing, warping or twisting to provide a straight, plumb and level substrate for applications of other materials.
