The Pacific Lumber Company Completes New Glulam Shipping Structure to Handle Mixed-Car Shipments

To meet demand for its special mixed-car service on redwood, fir and fir plywood, The Pacific Lumber Company has completed a modern 65,100 sq. ft. all-wood shipping structure, at its Scotia, California mill. The building assures completely covered storage and loading area required for the complex job o{ assembly and handling, prior to mixed'car loading.

Among ihe features of the building are the extensive use of wood construction, the giant glue laminated columns, and a high' speed 100-foot overhead crane. The main building is 105' wide by 62A long and 47' high to the lower chord of the I05' clear span trusses. Along the side of this main building is a 32' wide lean-to, 500'long and24'in clear height.

items. Nearly 90,000 sq. it. of half-inch CD Exterior Plyscord was used for the roof deck. The wall sheathing consisted of 43,000 sq. ft. of half-inch medium tensity overlaid plywood, installed horizontally with a horizontal lap joint and with all vertical jointsfilled with Hypalon mastic. Approximately 2z[5,000 board feet of glulam was required to fabricate the over 200 members comprising beams. columns. and truss lower chords used in the structure'

The Pacific Lumber Company's basic specification was that the building should be of wood. After the overall dimensions and and requirements were laid down by the owners, the specific design was worked out by Tim'Con, Inc' in consultation with Mr. Willi"tn Van Beckum, Vice-President in charge of Research and Development, and Mr' John Martin, Development Ensineer of The Pacific Lumber Company. Glulam was used for beirns, columns and other heavily stressed members because long experience with this material proved its greater strength, utility und ""ono-y in structural design. The glulam crane rail beams proved to be lower in cost than any other comparable structural material. For all their economy, these beams and columns provide greater strength to weight ratio, dimensional stability qd fire salety than other materials. The glulam members were fabricated to exact detail in the plant of Fluor Products Company of Santa Rosa, while the solid sawn heavy timber material for the trusses was {abricated at the Tim-Com plant at Richmond, California.

With the major elements pre{abricated at plants especially equipped for such work and with field fabrication of modular pu.r"l. io. installation on walls and roof decks, the result was u.,usual speed o{ erection and excellent economy. The entire job, including foundations was completed in approximately five months'

Beside the normal live and dead loads including earthquake loadings, the structure was designed to resist both the lateral and longitudinal forces resulting from the operation of a 100' span brilge crane which imposed a total load of 50,000 pounds' The glue-laminated columns and the lean-to bents of the same rnaterial were designed to resist these {orces.

Approximately 220,000 board feet of solid sawn lumber was t."d itt the walis, roof framing, trusses and other miscellaneous

BRI Announces Spring Conferences

The Building Research Institute will hold its 1963 Spring Conferences at the Shoreham Hotel, Washington, D. C., April 23 to 25. Eight separate programs, covering as many different areas of building science, have been tentatively scheduled.

Individual programs will range in length from half'day sessions to others lasting two full days. Topics to be included will be:

Structural adhesives

Plastics panels

Preassembled panels

Coating concepts for the maintenance of commercial and industrial structures

Noise control in electrical and mechanical systems

Construction of thin shell concrete structures

Innovations of the new IBM Building in New Orleans

Finishes for and new structural applications of metals

Open to the interested 'public as well as to BRI members and guests, the BRI Spring Conferences will be attended by architects, engineers, building owners and operators, manufacturers, contractors, builders, and technical representatives of industry, educational institutions, and government agencies.

Information about registration and further details about the conferences may be obtained from Milton C. Coon, Jr., Executive Vice President, Building Research Institute, L725 De Sales St., N.W., Washington 6, D.C.
