UNIVERSITY OF CALIFORNIA COLLEGE OF AGRICULTURE AGRICULTURAL EXPERIMENT STATION BERKELEY, CALIFORNIA A FARM-LABOR MESS HALL WITH KITCHEN L. W. NEUBAUER' 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 to provide a semipermanent farm housing structure. It is simple in design, provides adequate floor space, and is well lighted and ventilated. When proper- ly arranged in a camp group, it presents a neat appearance; moreover, it provides a structure which meets the requirements of f he 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 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 Arrangement The illustrations show a two-room 16 x 24 foot mess hall and kitchen. The mess hall will accom- modate two tables of 8- to 10-men capacity each. The kitchen provides adequate floor space for equipment for the preparation and serving of food. Framing The finished floor is about 12 inches above ground level, with the 4x4 inch stringers laid on concrete 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 detail 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 4 feet apart across the ceiling line (plan detail D) , with a 1x6 inch vertical stay from ridge to tie, should all be included to provide rigid framing. (For a concrete floor, see "Alternate Construc- tion.") 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 Assistant Professor of Agricultural Engineer- ing and Assistant Agricultural Engineer in the Experiment Station. 2 Associate in Agricultural Engineering. 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 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 surfacing the walls directly over the roll roofing. It is reasonable to assume that dry lumber of the pat- tern 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 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 as is done with the walls. If possible, however, a more per- manent 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 four-light, single-sash type, 2 feet 6 inches by 3 feet in size, except two over the kitchen sink which are 2x2 feet. 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 (supported by a chain) , or ordinary double-hung windows may also be used. Screens should be installed on all windows. The wall shutters as shown provide for addi- tional summer ventilation, and are constructed of material similar to the exterior walls. They are hinged to hang flat against the wall in the closed position and should lap the opening on all sides. Wood props hinged below each shutter swing upward to hold it in the open position. Standard full-panel or panel-and-glass doors may be installed for the exterior openings. Panel doors are recommended for the interior openings. The screen doors may be of the full-screen or the screen-and-panel type. Built-in Equipment The kitchen storeroom should have 8-foot walls and a tight ceiling. It is equipped with 1 x 12 inch shelves spaced about 12 inches apart. The shelves which extend over the drainboard are also 1 x 12 inch material built up to door height. Shelves beneath the drainboards may be as desired. UNl^ ) ,1 COLU- / iE O .(CULTURE DAVIS [1] Head ^^ Frame Construction with Drop-in Sash 2"x 6" Joist 2 4' o.c. ...

Interior Wall Surfaces No finish for the wall interiors is suggested at this time, other than for the partition wall separating the kitchen and mess hall. For this wall, the kitchen side may be sheathed to the raf- ters, using 1/8 inch shiplap laid horizontally. If a more finished structure is desired for post- war occupancy, the interiors may be sheathed with tongue-and-groove lumber, plain boards and bat- tens, or wood or composition panels. A ceiling should not be necessary with tight, smooth-sur- faced, roof sheathing. Chimney 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 the minimum requirements of the Electrical Safety Orders of the California Industrial Accident Com- mission. Two ceiling lights over each table in the mess hall and two in the kitchen as shown, are listed. A convenience outlet near the re- frigerator and a duplex outlet for electric equipment placed over the drainboard, are recom- mended. The mess hall and kitchen lighting should be controlled by wall switches. Plumbing All plumbing work is to be in full accordance with local ordinances or the standard code draft- ed and sponsored by the Pacific Coast Plumbing Inspectors Association. For the kitchen, a 32x20 inch double basin flat-rim sink is listed; a water boiler may be desired. Water supply and waste disposal lines outside the building are not listed. 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 rustic or other wood exterior finish is used, it may all be protected with paint. Bill of Materials Foundation Stringers Joists . . Bridging . Floor . . Plates . .

Alternate Construction '//here good drainage is obtainable a concrete floor may be desired. It provides a satisfactory floor for a mess hall; it is easy to clean and keep in good condition. 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 off the mess hall floor, and affords protection to the lower woodwork, is shown in plan detail C. If a concrete slab is desired, deduct the fol- lowing from the materials list: items 1 to 5, in- clusive; 8 pounds 8d common nails; and 3 pounds 20d common nail-s. Then add: 30 sacks Portland cement 4 cu. yds. sand kh cu. yds. gravel (fill not estimated) 24 only, 2" x 7" carriage bolts 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 2\ gal. paint g 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 criti- cal materials listed as additions to, or deduc- tions from, the original list should be corrected in the rough summary of materials.
