The Department of Housing and Urban Development has issued a new manual for builders on how to continue building homes in foul weather, particularly during cold months.

The "All Weather Home Building Manual" was written by the Research Foundation of the National Association of Home Builders, under contract with HUD and the Department of Labor.

The manual suggests that builders in cold weather areas "plan for winter construction by preparing access roads and installing utilities by late fall." Builders in these areas should also dig and pour foundations before the heavy frost sets in, the booklet says.

Also explained is scheduling for important construction stages, such as excavation, foundations and concrete-pouring , without prolonged work interruptions during bitter cold.

Covering lots with hay, for instance, will cut 12 to 16 hours of excavation time to four to six hours on lots with three feet of ground frost, the booklet suggests.

Temporary or permanent heat for workers can be hooked up as soon as the house is enclosed, it was noted. If the hookup is permanent, the furnance is often hung by metal straps from first-floor joists until the basement floor poured; temporary heat is usually provided by propane or oil-fired portable stoves.

Copies of the manual cost $2.70 and are available from the Government Printing Office of from room 8126 at the HUD building, 451 7th St. SW, Washington, D. C. 20410.
