2006 New York Code - Inspections.

 
    § 27-607 Inspections. Inspection of concrete and concrete construction
  shall  conform  to  the  requirements  of  tables  10-1 and 10-2 and the
  provisions of this subchapter.
    (a)  Controlled  inspection.   Controlled   inspection   of   concrete
  construction shall include:
    (1)   STRENGTH  TESTS.  Strength  tests  shall  be  performed  on  all
  structural concrete. The provisions of reference standard RS 10-3  shall
  apply.  A licensed concrete testing laboratory shall, in compliance with
  reference standards  RS  10-17,  RS  10-51  and  RS  10-52,  sample  the
  concrete,  make  and  cure the test specimens at the job site, transport
  the specimens to the laboratory and test the specimens  for  compressive
  strength.  Written  reports  of  the  results  shall be furnished to the
  architect or engineer designated for controlled inspection  and  to  the
  concrete producer immediately, but not more than five days following the
  conclusion  of  the  compression strength tests. Test specimens shall be
  stored on the job site in an insulated curing box of sufficient size and
  strength to contain all the  specimens  made  in  any  four  consecutive
  working  days  and  to  protect  the  specimens from falling over, being
  jarred or otherwise disturbed during the period of initial  curing.  The
  box   shall  be  erected,  furnished  and  maintained  by  the  concrete
  contractor. Such box shall be equipped to provide the  moisture  and  to
  regulate  the  temperature  necessary  to  maintain  the  proper  curing
  conditions required by reference standard RS 10-52. Such  box  shall  be
  located  in an area free from vibration such as pile driving and traffic
  of all kinds. No concrete requiring inspection shall be delivered to the
  site until such storage curing box has been  provided.  Specimens  shall
  remain  undisturbed  in  the  curing box until ready for delivery to the
  testing laboratory but not less than sixteen hours. Specimens  delivered
  to  the  laboratory  prior  to  an age of forty-eight hours shall not be
  demolded prior to delivery. All specimens  shall  be  carefully  removed
  from  the box and transported to the laboratory by the licensed concrete
  testing laboratory  in  accordance  with  the  provisions  of  reference
  standard  RS  10-52.  All specimens shall be delivered to the laboratory
  before the laboratory closes at  the  end  of  the  second  working  day
  following the day the specimens were molded.  The date of arrival at the
  laboratory  shall be recorded on the specimen test reports. All concrete
  failing to meet the specified minimum  strength  requirements  shall  be
  rejected   by  the  architect  or  engineer  designated  for  controlled
  inspection pending verification of the adequacy of the  construction  as
  described in section 27-598 of article three of this subchapter.
    (2) ADDITIONAL TESTS. Each sample of fresh concrete made in accordance
  with  reference  standard  RS  10-51 for the purpose of molding strength
  test specimens shall be made under the supervision of the  architect  or
  engineer  designated  for  controlled  inspection.  Each sample shall be
  tested by the licensed concrete  testing  laboratory  to  determine  its
  slump  in accordance with reference standard RS 10-49, its entrained air
  content in accordance with reference standards RS 10-61  and  RS  10-62,
  its  unit  weight in accordance with reference standards RS 10-63 and RS
  10-64 and its temperature.  If  any  of  the  tests  fail  to  meet  the
  specified  requirements,  the  concrete  shall  be sampled again and the
  particular test that failed shall be repeated. If the second test  fails
  to  meet  the  specified  requirements,  then,  with the approval of the
  architect or engineer designated for controlled inspection,  adjustments
  shall  be  made  to the concrete in the mixer to correct the deficiency.
  Test specimens shall not be molded from any sample that did not meet the
  specified requirements nor shall the concrete from which the sample  was
  taken  be placed in the structure, provided, however, that such concrete
  may be used elsewhere  in  the  work  where  it  meets  or  exceeds  the


  specified  requirements,  but only with the approval of the architect or
  engineer designated  for  controlled  inspection.  In  such  case,  test
  specimens  shall  be  molded by the licensed concrete testing laboratory
  which  shall  also  record  the  precise location where the concrete was
  placed in the structure.
    (3) CONTROLLED INSPECTION LOG BOOK. A controlled inspection log  book,
  limited  solely  to the concrete construction work, readily available to
  inspectors and representatives of the department, concrete suppliers and
  the architect and/or engineer of record, shall be maintained at the  job
  site  by the architect or engineer designated for controlled inspection,
  who shall make therein daily entries pertaining to the progress  of  the
  work.  The  entries shall describe, but not be limited to, the location,
  size and dimensions  of  the  concrete  members  for  which  forms  were
  constructed  that  day; the reinforcement installed in, and the specific
  locations  and  time  spans  of,  every  concrete  placement;  the   air
  temperature,  wind  velocity  and direction and other weather conditions
  during the twenty-four hours after  concrete  has  been  placed,  speci-
  fically at eight a.m., noon and four p.m., the protections taken against
  excessive  temperatures and adverse weather conditions at each placement
  made that day; the methods used, to cure the  concrete  and  the  period
  during  which  such  methods were maintained; the actual hour when forms
  were stripped and shores were reinstalled and tensioning was applied  to
  all   prestressed   members.   The  log  shall  become  a  part  of  the
  documentation to be filed with the commissioner as provided  in  section
  27-606  and  shall  include the attestation of the architect or engineer
  designated for controlled inspection that the concrete construction work
  complies with the approved plans and the provisions of this code.
    (b) Other required inspection. Quality control or inspection shall  be
  provided  with  respect to all operations of mixing and placing concrete
  and reinforcement that are not designated for controlled inspection.  In
  the  case  of  sidewalks,  curbs,  paving,  slabs-on-grade  and any work
  designated in table 10-1  under  the  caption  "Elements  That  Are  Not
  Subject  to  Controlled  Inspection"  or in table 10-2 under the caption
  "Operations on Structural Elements That Are Not  Subject  to  Controlled
  Inspection,"  all inspections shall be subject to and in accordance with
  the requirements of subdivision (b) of section 27-132. If  any  test  to
  determine  the  quality  or  compressive  strength  of  the  concrete is
  required, the fresh concrete shall be  sampled  and  tested  for  slump,
  entrained air content, unit weight and temperature. Compression strength
  test  specimens  shall  be  molded  only  by a licensed concrete testing
  laboratory or by a person certified by the American  Concrete  Institute
  as  qualified to perform such function. Attestation shall be executed by
  the person superintending the use of the material in accordance with the
  requirements of subdivision (b) of section 27-132 of  article  seven  of
  subchapter one of this chapter.
