Any logical system used in the preparation of an estimate for land and sea !
pipelines and offshore facilities must Ье based оп, and confined to, certain pre- ;
determined parameters. Тherefore,your particular аttеп~jQ;ц.isdirected to the
following:
No consideration has been given to the dollar value of labor, materials
or construction equipment. Тhe dollar cost oflabor and material
will vary, depending оп location and tiше or schedule of the particular
project. Outside or third party rental/purchase of construction
.equipment will vary, depending оп location, availability and the
market value at the time the equipment is needed. Ifthe equipment is
contractor-owned, its costs will vary depending оп its depreciated
value, cost of repairs and maintenance, insurance, desired return оп
investment, etc.
It is ofthe utmost importance that the correct labor crews and equipment
spreads Ье established and used. No piece ofequipment can
function properly without its complement of skilled labor to operate
and maintain it, and labor cannot produce efficiently without the
proper tools and equipment to accomplish the job intended.
Where size or capacity is listed with а piece of equipment in the
equipment spreads, it is intended solely as а guide and should not ье
construed as the only size or capacity that can Ье used. In actual
practice, the project scope and conditions will dictate the size, type
and capacity of the equipment to Ье used. The time frame tables in
this manual аге based оп employing the number and type of units
listed in the spread tables.
In keeping with the many time fгаше tables wblch appear throughout
this manual, the labor crew and equipment spread tables are
intended to provide ample labor and equipmentfor the installation of
аll items listed. In addition to the General Notes and the notes that
appear with the individual tables, consideration should ье given to
the following when forming and applying these crews and spreads.
