3.2.6.2
Rigid Frogs
Install crane track rigid frogs atop steel base plates and align vertically
be means of leveling nuts as indicated. Connect to adjacent crane rails
[and railroad rails] by means of [bolted] [welded] joints.
3.2.6.3
Turntable Frogs
Install frog [and throw mechanism] atop steel base plates and align
vertically by means of leveling nuts as indicated. Connect fittings to
adjacent rails by means of [bolted] [welded] joints. Install throw arm
complete in housings as indicated. Mechanism shall operate smoothly and
reliably, and hold the turntable in position securely, against motion of
crane wheels.
3.2.7
Standard Gage Railroad Tracks
Install in accordance with Section 05650 RAILROAD TRACK AND ACCESSORIES.
3.2.8
Oiling Track Fixtures
Swab [track bolts,] [switch points,] [throw mechanisms,] and [joint bars]
with oil specified.
3.2.9
Concrete
Install concrete for flangeways [, grade beams] and [encasements] in
accordance with basic or short form Section 03300N CAST-IN-PLACE CONCRETE.
3.3
CLEANUP
Upon completion of the work, clear job site of equipment, surplus material,
and debris. [Dispose of such material [off Government property] [at the
site indicated].] [Disposal shall be as required in Section 01575N

FIELD QUALITY CONTROL
3.4.1
Test for Grout
Verify nonmetallic, nonshrink grout strength during placement of grout at
daily intervals by molding and testing standard cubes of samples taken at
the job site. Take three test cubes each day for grout placed that day.
Mold and cure test specimens in accordance with ASTM C 109/C 109M. Furnish
necessary labor, materials, and facilities for molding the samples and for
handling and storing the cubes at the site of the work. Transport cubes to
the laboratory not sooner than 24 hours after molding. Test specimens for
compressive strength in accordance with ASTM C 109/C 109M. For evaluation
of grout strength, each strength test result shall be the average of the
strengths of specimens tested at 3 days.
3.4.2
Visual Inspection
Inspect rail fittings thoroughly. Inspect for defects that might hinder
satisfactory operation. [Inspect bolted joints for loose bolts and smooth
transitions between rails of different sections.] Inspect each welded
joint thoroughly after removal of the mold and grinding of excess metal.
Correct or replace welds containing surface cracking, slag inclusion, gas
pockets, and lack of fusion. Method of correction shall be as approved by
SECTION 14606N
