				or by employees of the manufacturer
Applies to the set up of factory built housing units such as
				mobile/manufactured homes, modular homes, or prefab cedar homes by contractors
				who work independently from a sales dealership or by employees of the
				manufacturer. This classification includes, but is not limited to, delivery of
				the factory built unit when performed by the set up contractor. The set up
				process includes placement of the unit or unit sections on blocks or
				foundations; joining the interior and exterior sections which may involve
				incidental placement of ridge cap, siding, trim boards, moldings, and interior
				seams; plumbing and electrical connections; and the installation of skirting,
				awnings or decks.
This classification excludes mobile home or factory built
				housing sales dealerships who set up and/or deliver the unit to a sales
				location or customer's site which are to be reported separately in
				classification 3415; the delivery of a mobile home or other factory built
				housing unit by a trucking service which is to be reported separately in
				classification 1102; the pouring of foundations; and/or the construction of
				nonstructural sheet metal patio covers/carports, garages or storage sheds
				regardless if performed by employees of the set up contractor or by another
				contractor which is to be reported separately in the applicable
				classification.
0517-01 Building raising, moving and
				underpinning
Applies to contractors engaged in raising, moving and
				underpinning buildings. Work contemplated by this classification includes a
				variety of services involving the change of a building's elevation, location or
				support structure including incidental shoring and removal or rebuilding of
				walls, foundations, columns or piers. Employees of the contractor responsible
				for the overall completion of the project are to be reported in this
				classification.
Underpinning
is a process to correct wall
				cracks, foundation settling or collapse of a building or structure. Generally,
				underpinning involves one of two methods. In the first method, earth around a
				foundation is removed to permit construction of a new foundation to replace the
				old one or to allow for the installation of subfoundations to support the
				existing earth. This would include masonry or concrete work, blasting (when
				required) and shoring of surrounding ground and building or structure to
				prevent cave-ins while foundation work is being performed. The second method
				deals with steel or wooden beams being inserted through a lower point of the
				building or structure. The beams are raised and supported by jacks until the
				foundation is relieved of some or all of its ground pressure.
Building
				raising or moving
is a process to change a building's position, either
				raised to a new elevation in place or moved to a new site, or both. Workers,
				subcontractors or utility companies will first disconnect all utilities from
				the building or structure to be moved. Workers will remove all detachable items
				and open foundation walls to allow metal or wood beams to be placed under the
				floor structure. Once beams are placed, hydraulic jacks are used to lift the
				building or structure clear of the old foundation high enough for a new
				foundation to be constructed, or high enough to allow the carrying vehicle
				(trailer) to be placed under the beams if it is to be moved. The trailer is
				moved along a previously graded and cleared path to the new location. The
				building or structure is then set down on a new foundation which is usually
				constructed by a separate contractor. Miscellaneous repair work is performed
				and utilities are reconnected.
This classification excludes contractors engaged in clearing
				paths, grading and excavation work who are to be reported separately in
				classification 0101; contractors who disconnect or hook-up underground gas,
				water or power lines who are to be reported separately in classification 0107;
				contractors who construct concrete foundations for wood frame or nonwood frame
				buildings who are to be reported separately in classification 0217, or in
				classification 0518 as applicable; and contractors engaged in the delivery and
				set up of factory built housing units who are to be reported separately in
				classification 0517.
