or modular component, or for REF builders, the location of the decal
on the building;
(19) compliance control manual (reference subsection
(c)); and
(20) on-site construction documentation (reference
subsection (d)).
(c) Compliance control program for manufacturers. The
utilization of mass production techniques and assembly line methods
in the construction of industrialized housing, buildings, modules,
and modular components along with the fact that a large part of such
construction cannot be inspected at the ultimate building site, requires
manufacturers to develop an adequate compliance control program to
assure that these structures meet or exceed mandatory code requirements
and are in compliance with the rules and regulations of this chapter.
The compliance control program shall be documented in the form of
a manual that must be approved by the design review agency. A 100%
inspection of the construction of industrialized housing or buildings
may be authorized in lieu of a compliance control program and certification
of the manufacturer in accordance with §70.60. The manufacturer
shall provide the design review agency a compliance control manual
that must, at the minimum, contain the following:
(1) a table of contents;
(2) a chart indicating the manufacturer's organizational
structure to assure compliance and to assure that the compliance control
staff shall maintain independence from the production personnel;
(3) a statement that defines the obligation, responsibility,
and authority for the manufacturer's compliance control program;
(4) identification of compliance control personnel,
their accountability by position, responsibility for inspections,
method of marking nonconformances observed, and system for assuring
corrections are made;
(5) materials handling methods, including inspection
checklists, for receiving materials and methods for marking and removing
rejected materials both upon receipt and from the production line.
The area for rejected materials must be clearly indicated to assure
that such material is not used;
(6) a description of an identification system to mark
each individual module, or modular component, at the first stage of
production to assure appropriate inspection and rechecking of any
deviation corrections;
(7) a diagram of the manufacturing sequence with the
plant layout, including a description of the activities to be performed
along with a listing of those that may be performed at one or more
stations;
(8) an inspection checklist including:
(A) a list of inspections to be made at each production
station; and
(B) accept/reject criteria (each significant dimension
and component should be given tolerances);
(C) an energy compliance checklist that enumerates
the energy code-compliance features of the module or modules and includes
a signature space for the compliance control inspector or manager.
A copy of this checklist shall be shipped with the module or modules.
(9) step-by-step test procedures, a description of
the station at which each production test is performed, a description
of required testing equipment, and procedures for periodic checking,
recalibration, and readjustment of test equipment. Procedures shall
be included for, but not limited to, electrical tests as specified
in the National Electrical Code, Article 545.14 (as added by §70.101(j)(2)),
gas supply pressure tests, water supply pressure tests, drain-waste-vent
system tests, concrete slump tests, and concrete strength tests;
(10) storage procedures for completed structures at
the plant and for any other locations prior to installation;
(11) a statement indicating the person who is responsible
for compliance control at each manufacturing facility and who will
assume responsibility for decals and insignia, application of the
decals and insignia, and the reporting procedure;
(12) a procedure for maintaining reliable, retrievable
records of the inspections performed, decal and insignia numbers assigned,
the deficiencies and how they were corrected, and the site to which
the modules or modular components were transported;
(13) procedures and information to demonstrate how
the modules and modular components are to be transported to the building
site so that damage will not occur or that compliance deviations will
not result (actual transportation without damage or deviation is evidence
sufficient to justify the method); and
(14) procedures that assure that the compliance control
procedures are complied with on all regulated structures. As a minimum,
regulated structures must be identified prior to commencing construction.
(d) On-site construction specifications or documentation
for manufacturers. All work to be performed on the building site shall
be specifically identified and distinguished from construction to
be performed in the manufacturing facility, e.g., assembly and connection
of all modules, modular components, systems, equipment, and appliances
and attachment to the foundation system. The work to be performed
on-site shall be described in detail in documents (architectural sheets,
specifications, instructions, etc.) which shall be made available
to the builder for use at the site and provided as required for review
and inspection to the agency having local authority. The manufacturer
shall provide the design review agency on-site construction documentation
which must, at the minimum, contain the following:
(1) critical load points for attachment of the house
or building or component to the foundation;
(2) details for module to module or modular component
assembly and connection;
(3) minimum requirements for connection and attachment
of all modules and modular components to the foundation system;
(4) firestopping and draftstopping details;
(5) details for fire exits, balconies, walkways, and
other site-built attachments;
(6) exterior weatherproofing details;
(7) details for thermal, condensation, decay, corrosion,
and insect protection;
(8) electrical, mechanical, heating, cooling, and plumbing
system completion details;
(9) electrical, mechanical, heating, cooling, and plumbing
system test procedures;
(10) fire safety provisions; and
(11) specifications and instructions for cooling equipment,
and complete information necessary to calculate sensible heat gain
along with information on the sizing of the air distribution system,
if applicable, and the R values of insulation in the ceiling, walls,
and floors.
(e) Other construction documentation for REF builders.
Construction documentation for the foundation and site specific elements,
such as ramps and stairs, of the site-built REFs shall be reviewed
and approved by the DRA, the local building official, or, in areas
where the building site is outside a municipality or within a municipality
with no building department or agency, by the school district. At
a minimum the documentation shall include all construction documentation
necessary to complete the building at the first commercial site including
a foundation system design meeting the requirements of §70.73(h).
The use of ground anchors shall comply with §70.73(i).
(f) Non-site specific buildings. Whenever the manufacturer
does not know, at the time of construction, where the building is
to be placed, in lieu of providing the site specific construction
details or typical site construction details as required in subsection
(d), the manufacturer may provide special conditions and/or limitations
on the placement of the building. These special conditions and/or
limitations will serve to alert the local building official of items,
such as handicapped accessibility and placement of the building on
the property, which the local building official may need to verify
for conformance to the mandatory building codes. Certain site-related
details, such as module to module connections, must still be provided
by the manufacturer. It is the responsibility of the DRA to verify
that such site-related details are included in the manufacturer's
approved design package.
