dowels, or tie bars, shall be installed to meet the specified tolerances.
Care shall be taken during placing adjacent to and around dowels and tie
bars to ensure there is no displacement of the dowel or tie bar and that
the concrete completely embeds the dowel or tie bar and is thoroughly
consolidated.

FINISHING FORMED SURFACES
**************************************************************************
NOTE: Formwork, form materials and form
construction are specified in Section 03100A
STRUCTURAL CONCRETE FORMWORK. Classes of finish to
be used for various formed surfaces of the structure
must be indicated on the drawings or clearly
specified herein. Criteria to use in choosing class
of finish are as follows:
Class A Finish. This finish is for surfaces
permanently exposed to public view that require
excellent appearance at close range. Examples:
Exterior walls of office and residential buildings,
of warehouse/industrial type buildings where
frequent public access occurs, and of other similar
exposed structures; and interior walls, columns or
beams of these same structures where no other finish
treatment is to be added.
Class B Finish. This finish is for surfaces exposed
to public view that do not require the excellent
appearance of Class A. Exterior walls of warehouse/
industrial buildings where public access is
infrequent, structures on combat training ranges,
and other similar exposed structures; interior
exposed surfaces of such structures, and interior
surfaces of liquid containers.
Class C Finish. This finish is for concealed
surfaces not exposed to view and for all surfaces
not covered by Class A, B, or D finish. Examples:
Interior surfaces that will be covered by dry wall
or other applied surfaces, surfaces of mechanical
rooms and elevator shafts.
Class D Finish. This finish is for surfaces where
roughness and irregularities are not objectionable.
Examples: Walls and foundation surfaces against
which backfill will be placed, exterior surfaces
permanently submerged in water where no coating is
to be applied.
When a Class A or B Finish is specified, add to
paragraph FIELD TEST PANELS in PART 1 requirements
for the Contractor to construct a sample panel for
approval before start of construction. Finishes for
surfaces to be exposed to high velocity flow of
water (above 40 ft per sec) will be designed and
constructed in accordance with Civil Works criteria.
