Conditions and limitations
The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.
- The product, as with all SCL, is intended for dry service applications only.Footnote (1)
- The product is intended for use in construction as an alternative material to lumber. Proprietary design values presented for the product are to be used by professional engineers for design in accordance with CSA O86 for structural applications such as beams, headers, joists, rafters, and columns as intended by the product manufacturer. The specific application must be qualified through testing and validated by the manufacturer. Applications such as I-joist flanges, studs and metal-plated truss chords are beyond the scope of this evaluation.
- Structural applications:
- Pacific Woodtech Corporation’s pre-engineered tablesFootnote (2)Footnote (3)
The pre-engineered tables in the literature outlined below have been provided to CCMC by the manufacturer to demonstrate compliance with Part 9 buildings of Division B of the NBC 2010 for acceptance by the local authority having jurisdiction (AHJ):
When the product is used as beams, headers and rim boards to support uniform loads only, the installation must be in accordance with the tables and installation details published by Pacific Woodtech Corporation entitled:
- “Pacific Woodtech™ LVL Technical Guide 2.0E 2900Fb - Limit States Design,” dated December 2022;
-
The product must be installed in accordance with the manufacturer’s installation guidelines noted in the above-mentioned documents for those applications falling within the scope of these documents. Applications outside the scope of these installation guidelines require engineering on a case-by-case basis.
- Pacific Woodtech Corporation’s installation details
Pacific Woodtech Corporations’s pre-engineered details within the documents outlined in (i) above are limited in scope to building designs where the anticipated loads on the following structural details will not be exceeded:
- beams supporting floor loads (pages 5 and 10 of (1));
- beams supporting roof loads (pages 8, 9, and 17 of (1));
- beams supporting floor and roof loads (pages 6 and 7 of (1));
- Engineering required
For structural applications beyond the scope/limitations of the above-referenced publications or when required by the AHJ, the drawings or related documents must bear the authorized seal of a professional engineer skilled in wood design and licensed to practice under the appropriate provincial or territorial legislation. Installations beyond the scope/limitations of (i) and (ii) above imply, but are not limited to, the following:
- higher loads/longer spans than the manufacturer’s pre-engineered details;
- concentrated loads;
- areas of high wind or high seismicity;
- design of supporting members/columns when the total beam/header load exceeds the NBC 2010 pre-engineered beam/lintel tables; and
- design of supporting foundation footings when the total load exceeds the NBC 2010 pre-engineered floor/roof joist tables.
The engineer must design in accordance with CSA O86 and may use the “Engineering Guide for Wood Frame Construction” (published by the Canadian Wood Council) as a guide.
The specified strengths for the product must not exceed the values set forth in the Product specified strengths (MPa) table. See Figure 1 for details about veneer orientation.
Basic nail, bolt and lag screw capacities must be as shown in the Equivalent specific gravity for the product fastener design table. Nail spacing of the product must conform to the Product nail spacing requirements table.
The ends of all beams must be restrained to prevent rollover. This is normally achieved by attaching a diaphragm sheathing either to the top or compression edge, and an end wall or shear transfer panel capable of transferring a minimum unfactored load of 730 N/m or required shear forces due to wind or seismic conditions. Blocking or cross-bracing with equivalent strength may be used. The compression edges of all beams must be laterally supported at least every 610 mm, except where design is done in accordance with CSA O86.

Appendix A
The initial design values obtained from testing to ASTM D 5456-01, “Standard Specification for Evaluation of Structural Composite Lumber Products,” as specified in CAN/CSA-O86-01, “Engineering Design in Wood,” are summarized below. Confirmation from the third-party certification agency with respect to product compliance with ASTM D 5456-07 (as specified in CSA O86-09) was provided, namely in relation to the following aspects (i) durability, (ii) evaluating bond quality, (iii) duration of load and creep effects, and (iv) alternative horizontal shearstress test procedures.
Property | Test information |
---|---|
Bending | Specimens were tested in edgewise and flatwise bending to establish the characteristic value. Qualification test data were used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from CSA O86-09 was used to determine the specified strength. |
Shear | Specimens were tested in shear (using block shear and then using structural-size horizontal shear-stress test procedures) to establish the characteristic value. Qualification test data were used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from CSA O86-09 was used to determine the specified strength. |
Compression parallel to grain |
Specimens were tested in compression parallel to grain to establish the characteristic value. Qualification test data were used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from CSA O86-09 was used to determine the specified strength. |
Compression perpendicular to grain |
Specimens were tested in compression perpendicular to grain to establish the characteristic value. The characteristic value was multiplied by 1.09 to establish the specified strength in accordance with CSA O86-09. |
Tension parallel to grain |
Specimens were tested in tension to establish the characteristic value. Qualification test data were used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from CSA O86-09 was used to determine the specified strength. |
Nail withdrawal | Nail withdrawal values were established following ASTM D 1761, “Standard Test Methods for Mechanical Fasteners in Wood,” for a 6d common nail having a 31.75-mm (1¼ in.) penetration. Specimens were tested and equivalent species capacity was determined in accordance with Annex 2 of ASTM D 5456-07. |
Nail bearing | Dowel bearing strength was determined in accordance with ASTM D 5764-95, “Standard Test Method for Evaluating Dowel-Bearing Strength of Wood and Wood-Based Products,” with 10d common nails with a nominal diameter of 3.76 mm and a lead hole diameter of 2.77 mm. Specimens were tested and the mean bearing capacity was used to establish the equivalent species capacity as per Annex 2 of ASTM D 5456-07. |
Bolt bearing | Bolt bearing capacity was determined in accordance with ASTM D 5764-95, with 13-mm (½ in.) and 19-mm (¾ in.) bolts. Specimens were tested and the mean bolt bearing capacity was used to establish the equivalent species capacity in accordance with Annex 2 of ASTM D 5456-07. |
Creep | Twelve (12) specimens of the product were tested in accordance with the CCMC Creep and Recovery Test, resulting in acceptable performance. Long-term (90-day) creep testing was also conducted. It demonstrated equivalency to duration of load behaviour of sawn lumber. See Note 1(4) below for further information. |
Bond quality | Specimens were tested for shear strength in the L-X plane in accordance with ASTM D 143 and the percentage of wood failure was evaluated and reported in accordance with ASTM D 5456-07. |
Edgewise bending durability | Specimens were tested for edgewise bending durability in accordance with Annex A4.3 of ASTM D 5456-07. The average strength retention was greater than or equal to 75%. |
Adhesive | The adhesives used comply with CSA O112.6-M1977, “Phenol and Phenol-Resorcinol Resin Adhesives for Wood (High-Temperature Curing).” For the Golden plant, see CCMC 13192-L; for the Wilmington plant, see CCMC 13322- L; and for the Sutherlin plant, see CCMC 13019-L. |
