SECTION 06196

PLYWOOD WEB JOISTS

[PART 1: GENERAL]{.underline}

1.1 SUMMARY:

A. Section Includes: Furnishing and installing plywood web wood joists.

1.2 SUBMITTALS:

A. General: Submittals shall be according to \[Section 01009 - General
Information and Requirements.\] \[and\] \[Section 01300 - Submittals.\]
\[and\] \[Section 01365 - Certificates of Conformance.\]

B. Manufacturer\'s Literature: Submit 1 copy of the manufacturer\'s
descriptive data appropriately marked to indicate proposed joists to be
used on this project.

C. Shop Drawings: Submit \[\_\_\] copies of shop \[and erection\]
drawings indicating positions of all joists complete with large scale
details of support, bracing, live and dead load design criteria to be
used on this project.

D. Design Computations: Submit 1 copy of design calculations for
verification of joist design. The joists shall be sized and detailed to
fit the dimensions and loads indicated on the drawings. All designs
shall be in accordance with allowable values and section properties
assigned and approved by the Uniform Building Code.

1.3 QUALITY ASSURANCE:

A. Failure Criteria: Not limited to the following:

1\. Evidence of wood fracture or cracking.

2\. Deflection under allowable loading which causes cracking of gypsum
board ceiling.

3\. Deflection under allowable loading sufficient to cause noticeable
sagging or springiness of flooring above.

1.4 DELIVERY, STORAGE, AND HANDLING:

A. Delivery: Remove from conveyance by individual man‑handling or with
crane and slings in a manner to minimize possible damage.

B. Storage: Prior to erection, store in vertical position and protected
from the weather.

[PART 2: PRODUCTS]{.underline}

2.1 MATERIALS:

A. Plywood Web Wood Joists: Shall be factory manufactured with
structural grade plywood webs and laminated or machine stress rated
lumber flanges. Waterproof type glues shall be used.

B. Plywood Webs: APA Structural I CD exterior grade or approved equal
with face veneers installed with grain running in the vertical direction
of the joist and butt jointed to form a continuous web member. The web
shall be pressure formed and fit into a groove in the center of the wide
face of the flange members so as to form a pressured glue joint at the
junction.

2.2 ACCESSORIES:

A. Requirements: Manufacturer shall provide the required blocking to
transfer all loads and the required bridging system, including
appropriate connectors, to laterally stabilize the joists at the points
of required lateral support as required by the shop drawings. As a
minimum, the following shall be furnished and installed:

1\. Two web stiffeners at each bearing with a minimum bearing length of
1-3/4 inch.

2\. Blocking panels if joists not installed in framing hangers.

[PART 3: EXECUTION]{.underline}

3.1 PREPARATION:

A. Requirements:

1\. Support members shall be completely and rigidly installed and to
proper bearing elevations.

2\. Sufficient man‑power or crane shall be available to expedite the
placement of joists.

3.2 ERECTION:

A. Joists: The joists shall be erected in accordance with the project
drawings, the approved shop drawings and installation details. Web
penetrations shall be approved with shop drawings.

B. Loading: Temporary construction loads which cause member stresses
beyond design limits shall not be permitted.

C. Bracing: Erection bracing in addition to specified bridging shall be
provided to keep the joists straight and plumb as required to assure
adequate lateral support for the individual joists and the entire system
until the sheathing material has been applied.

3.3 FIELD QUALITY CONTROL:

A. Inspection: The Contractor shall give notification prior to enclosing
the joists, for inspection of the installation.

[PART 4: MEASUREMENT AND PAYMENT]{.underline}

4.1 METHOD OF MEASUREMENT:

A. Units: The work described in this section will not be measured for
payment.

4.2 BASIS OF PAYMENT:

A. Payment: No direct payment for the work described under this section
will be made. Contractor shall include consideration for this item in
the bid price for other items of the Contract.
