SECTION 033000 - CAST-IN-PLACE CONCRETE

Sludge Treatment Project Engineered Container Retrieval and Transfer System January 2012
3.3 FIELD CONNECTIONS
A. High-Strength Bolts: Install high-strength bolts according to RCSC’s “Specification for
Structural Joints Using ASTM A 325 or A 490 Bolts” for type of bolt and type of joint
specified.
1. Joint Type: Snug tightened.
B. Weld Connections: Comply with AWS D1.1/D1.1M for tolerances, appearances, welding
procedure specifications, weld quality and methods used in correcting welding work.
1. Comply with AISC 303 and AISC 360 for bearing, alignment, adequacy of temporary
connections, and removal of paint on surfaces adjacent to field welds.
3.4 FIELD QUALITY CONTROL
A. Testing Agency: Engage a qualified independent testing and inspecting agency to inspect field
welds, high-strength bolted connections, and grout.
B. Bolted Connections: Bolted connections will be inspected according to RCSC’s “Specification
for Structural Joints Using ASTM A 325 or A 490 Bolts”.
C. Welded Connections: Field welds will be visually inspected according to AWS D1.1/D1.1M.
1. In addition to visual inspection, field welds will be tested and inspected according to
AWS D1.1/D1.1M and the following inspection procedures, at testing agency's option:
a. Liquid Penetrant Inspection: ASTM E 165.
b. Magnetic Particle Inspection: ASTM E 709; performed on root pass and on
finished weld. Cracks or zones of incomplete fusion or penetration will not be
accepted.
c. Ultrasonic Inspection: ASTM E 164.
d. Radiographic Inspection: ASTM E 94.
D. Grout Tests: Testing of grout obtained according to ASTM C 109 shall be performed according
to the following requirements:
1. Testing Frequency: Obtain at least one sample per location, but not less than one sample
for each bag of mix.
a. When frequency of testing will provide fewer than five compressive-strength tests
for each grout mixture, testing shall be conducted from at least five randomly
selected batches or from each batch if fewer than five are used.
2. Strength of each grout mixture will be satisfactory if every average of any three
consecutive compressive-strength tests equals or exceeds specified compressive strength
and no compressive-strength test value falls below specified compressive strength by
more than 500 psi.
3. Test results shall be reported in writing to Buyer’s Technical Representative, grout
manufacturer, and Contractor within 48 hours of testing. Reports of compressive-
