> 1\. General:

This Bulletin sets forth specific requirements under the Technical
Suitability of Products Program for determining the eligibility of
housing to be constructed under HUD mortgage insurance, or other HUD
housing programs.

> 2\. Scope:
>
> This Bulletin applies only to the structural features of this method
> of construction. Final determination of eligibility is made by the
> appropriate HUD Field Office. Other factors considered by the Field
> Office will be valuation, location, architectural planning and appeal,
> mechanical equipment, thermal characteristics, and market acceptance.
> Consideration is also necessary to determine whether a specific
> property will qualify under the specific HUD program, when constructed
> according to the method outlined in this Bulletin, and where the
> structure is to be located.

> In geographical areas subject to hurricanes, earthquakes, or other
> severe conditions affecting dwelling structures, the HUD Office shall
> require additional safeguards in proposed designs, when necessary.
>
> 3\. Minimum Property Standards (MPS):
>
> Compliance with HUD MPS will be determined by the HUD Office on the
> same basis as submissions involving conventional construction, except
> for the special features described in this Bulletin.
>
> 4\. Inspection:
>
> Field compliance inspections covering conventional items of
> construction and any special features covered in this Bulletin shall
> be made in accordance with prescribed procedures.
>
> The appropriate HUD Office shall furnish a copy of a HUD field
> inspection report to Headquarters, FHA Standards, Office of
> Manufactured Housing Programs, when there is:
>
> a\. Evidence of noncompliance with any portion of the system of
> construction described in this Bulletin.
>
> b\. Faulty shop fabrication, including significant surface defects.
>
> c\. Damage to shop fabricated items or materials due to improper
> transportation, storage, handling, or assembly.
>
> d\. Unsatisfactory field workmanship or performance of the product or
> system.
>
> e\. Any significant degradation or deterioration of the product or
> evidence of lack of durability or performance.
>
> Periodic plant inspections will be made by HUD designated
> representatives or State Agency personnel in accordance with their
> prescribed procedures. Factory inspection reports shall be submitted
> to HUD Headquarters, upon request.
>
> 5\. Certification:
>
> The manufacturer named in this Bulletin shall furnish the builder with
> a written certification stating that the product has been manufactured
> in compliance with the HUD Minimum Property Standards (MPS), except as
> modified by this Bulletin. The builder shall endorse the certification
> with a statement that the product has been erected in compliance with
> HUD MPS except as modified by this Bulletin, and that the
> manufacturer\'s certification does not relieve the builder, in any
> way, of responsibility under the terms of the Builder\'s Warranty
> required by the National Housing Act, or under any provisions
> applicable to any other housing program. This certification shall be
> furnished to the HUD Office upon completion of the property.

> [OUTLINE DESCRIPTION, CATEGORY II CONSTRUCTION]{.underline}
>
> [GENERAL]{.underline}:
>
> Completely shop fabricated field erected, building components for
> walls, floors and roofs of one- and two-story dwelling units are
> furnished in this method of construction. The components are
> transported to the site, where they are erected and assembled on
> conventional foundations.
>
> All materials and methods of installation shall be in accordance with
> HUD Minimum Property Standards (MPS), Use of Materials Bulletins (UM),
> and Materials Releases (MR), except as may be specifically noted
> herein. Plumbing, heating and electrical systems are field installed
> and connected.
>
> This Bulletin is based upon a structural review of the shop fabricated
> components of the one- and two-story model of 1001, Inc., but may be
> considered applicable to all structurally similar units of this
> company. Foundation design and nonstructural items (such as
> architectural, plumbing, heating and electrical features) are not
> covered by this Bulletin.

> [SPECIFICATIONS]{.underline}:
>
> Form HUD-92005, \"Description of Materials\" specifying only the
> structurally related items (Nos. 1 to 12, 14, 26 and 27), as

> same or similar structural features as shown on the drawings listed
> above. Copies of these listed drawings shall also be furnished to the
> HUD Office by the Builder upon request.

> [SPECIAL CONSTRUCTION FEATURES:]{.underline}
>
> Composite building panels of 4 feet x 8 to 12 feet in a three
> dimensional frame formed by a 2-inch-thick expanded polystyrene foam
> (EPS) embedded with a series of No. 10 gauge zig-zag wire bent in 60
> degree angles so that it is 3 inches in height and 4 inches from one
> zig-zag to the other, covered on each side by a layer of No. 10 gauge
> welded wire mesh 4 inches square (spacing of longitudinal and
> transverse wires) and 1-1/2-inch thick Portland cement plaster
> resulting in a finished wall thickness of at least 5 inches.
>
> 1\. Wire frame: Welded in accordance with AWS D1.1, ASTM A 82, and
> ASTM A 185 using No. 10 gauge wire minimum, with minimum fy=65000 psi.
>
> 2\. Expanded polystyrene foam: Foam shall be 2 inches thick with an
> approximate density of 1.0 to 1.5 pcf.
>
> 3\. Portland cement plaster: Mixture of Portland cement Type II and
> aggregate shall be in accordance with the HUD Minimum Property
> Standards. Plaster shall have a minimum 28 day compressive strength of
> 3000 psi. Portland cement aggregate and natural sand shall comply with
> ASTM C 150, ASTM C 144, and ASTM C 35 respectively.
>
> [Fire Resistance Requirements]{.underline}:
>
> The thickness of Portland cement sprayed concrete facing on each side
> of the panel shall be 1-1/2 inches.
>
> Foam plastics shall have a maximum flame spread rating of 25 and a
> maximum smoke-developed rating of 450 when tested in accordance with
> ASTM E 84. The interior of the building shall be separated from the
> foam plastic by an approved thermal barrier of fire resistive material
> having a finish rating of 15 minutes when tested in accordance with
> ASTM E 119.
>
> Caution shall be exercised in the use of foam plastics. Foam plastics
> when exposed or unprotected may, under some circumstances, produce
> rapid flame spread, quick flashover, toxic or flammable gasses, dense
> smoke, intense and immediate heat, and may present a serious fire
> hazard. The material shall not be used where directly exposed. The
> manufacturer of foam plastic or the Society of the Plastics Industry,
> Inc., shall be consulted for instructions to minimize the risk in the
> use of these products in manufacture and in construction.
>
> [DESIGN AND CONSTRUCTION REQUIREMENTS]{.underline}:
>
> [Design Loads]{.underline}: The method described in this Bulletin is
> based on maximum design loads of 20 psf for snow, Seismic Zone 3 and a
> Basic Wind Speed of 105 mph and Exposure C (ASCE 7-88). The Builder
> shall submit structural calculations to the local HUD Office if
> housing units are to be located in geographical areas where these
> conditions are exceeded.
