UNIVERSITY OF CALIFORNIA COLLEGE OF AGRICULTURE AGRICULTURAL EXPERIMENT STATION BERKELEY, CALIFORNIA A SIX-MAN BUNKHOUSE L. W. NEUBAUER 1 and H. L. BELTON 2 This plan is one of a series of labor-camp structures prepared to aid farmers in the selec- tion of suitable farm-labor housing during the war emergency, and, at the same time, provide a semipermanent farm housing structure. The bunk- house is simple in design, provides adequate floor space, and is well lighted and ventilated. When properly arranged in a camp group, it pre- sents a neat appearance; moreover, it provides a structure which meets the requirements of the State Labor Housing and Sanitation Act. Restrictions on Materials Farmers contemplating construction should familiarize themselves with available local ma- terials and should consult with county war boards and other Federal agencies to make certain that they are conforming with regulations regarding the use of any critical materials involved. In some cases, the use of substitute materials may be necessary. Size and Framing The illustrations show a six-man bunkhouse, 16 x 24 feet in size, to accommodate 6 cots. The finished floor is about 12 inches aboveground, level with the 4x4 inch stringers laid on con- crete or rot-resistant wood blocks. A tight tongue-and-groove floor laid on 2 x 6 inch joists placed on 2-foot centers is recommended (see plan A) . The framing for walls and roof is 2 x 4 inch stock, with the studding and rafters placed on 2- foot centers. Bracing and bridging in the walls, and ties 6 feet apart across the ceiling line (plan detail D) , with a 1 x 6 inch vertical stay from ridge to tie, should all be included to pro- vide rigid framing. Wall Exteriors The wall exteriors may be sheathed with one of the several styles of stock siding laid horizon- tally, or 1 x 12 inch boards and battens placed vertically. Only dry material should be used for the exterior siding. Under war conditions very little dry lumber, suitable for siding, is avail- able. Green lumber shrinks to such an extent that it may be necessary to remove and re-lay it after one season of exposure. In order to avoid this situation, it is suggested that the exterior wall surfaces be sheathed horizontally with com- mon 1x8 inch stock boards, or a common grade of shiplap. These surfaces may then be covered with a good grade of single-ply roll roofing laid ver- tically, with the joints and corners stripped Assistant Professor of Agricultural Engineer- ing and Assistant Agricultural Engineer in the Experiment Station. 2; "Associate in Agricultural Engineering. with battens or lath. The lower grades of lumber are acceptable for this type of sheathing and such shrinkage as occurs may be corrected as far as tightness is concerned by subsequently sur- facing the walls directly over the roll roofing. It is reasonable to assume that dry lumber of the pattern desired will be more readily available at a later date. The thinner, less expensive types of siding not generally placed directly on the studded walls are also suitable when applied over a tight-sheathed wall of this type. Roofing The roof surface should be tight-sheathed, and then may be covered with roofing paper similar to that used on the walls. If possible, however, a more permanent type of roofing material such as wood or composition shingles, galvanized iron sheets, or a heavy grade of roll roofing, should be applied. Windows, Doors, and Screens The windows are of the single-sash type, four lights, 2 feet and 6 inches by 3 feet in size. A drop-in sash supported by wood shields, and a sliding type, are shown in plan details A and B. Sash hinged at the bottom to open inward (sup- ported by a chain), or the ordinary double-hung type of window may also be used. Screens should be installed on all windows. A standard full-panel or panel-and-glass door' may be installed. A home- built door would also serve. The screen door may be either the full-screen or panel-and-screen type. Closets The clothes closets are constructed of panels or 1-inch lumber. They should have a tight top and be equipped with a hanger pole and shelf. A door is not necessary. A 12-inch shelf, supported by wood brack- ets, and placed on the closet wall above the cot, will prove convenient to the occupants. Interior Wall Surfaces No finish for the interior walls is suggested at this time. If a more finished structure is desired for post-war occupancy, the interior walls may be sheathed with tongue-and-groove lumber, plain boards and battens, or wood or composition panels. A ceiling should not be necessary with tight, smooth-surfaced, roof sheathing. Chimney (Optional) A galvanized iron chimney of stock design, lined with a 6-inch terra cotta flue and equipped with metal brackets, cleanout plate, and roof cap, is recommended. Electric Wiring Electric wiring shall be exposed wire with knob and tube installation of a type which meets [1] tvERsn • .

Two ceiling lights controlled from one wall switch near the entrance door, and a double convenience outlet located near the stove are listed. This will provide minimum lighting re- quirements. Painting Two coats of a good grade of lead-and-oil paint are recommended for all exterior woodwork. When walls are finished with roofing paper and battens, only the trim requires paint. If rus- tic or other wood exterior finish is used, it may all be protected with paint. Bill of Materials Foundation . . or Stringers . . Joists .... Bridging . . . Floor . . . Plates . . .

Alternate Construction Where good drainage is obtainable a concrete floor may be desired. It is easy to clean and keep in good condition, so provides a satisfactory floor for a bunkhouse. A 4-inch slab of 1— 2|--4 mix, with additional thickness at the outside edges for a footing, and a gravel fill beneath the slab to secure the proper elevation of the floor above grade, is recommended (plan detail B) . The concrete should be well tamped into place, and the surface edged true and given a smooth finish. Curing for several days with a bed of wet sand or straw is advisable. A curbed concrete slab which permits hosing out of the bunkhouse and affords protection to the lower woodwork is shown in plan detail C. If a concrete slab is desired, deduct items 1 to 5 inclusive from the materials list, and add: 30 sacks Portland cement 4 cu. yds. sand 4g cu. yds. gravel (fill not estimated) 16 only 5" x 7" carriage bolts 8 lbs. 8d. common nails 3 lbs. 20d. common nails If rustic siding is desired, deduct items 6, 7, 8, and 12 from the materials list, and add: 900 bd. ft. 1" stock rustic, pattern as desired 2g gal. paint 5 gal. linseed oil 1 qt . turpentine If roll roofing is desired, deduct items 9, 10, and 11 from the materials list, and add: 5 rolls 3-ply roofing paper Summary If alternate construction is used, the critical materials listed as additions to or deductions from the original list should be corrected in the rough summary of materials. 10m-6, '43 (6558c) [4]
