65001.01‑02 INSPECTION REQUIREMENTS AND GUIDANCE

02.01 [Procedures]{.underline}. This inspection procedure is intended to
verify that approved and effective oversight ensures that the
construction and quality control of foundations and buildings is in
accordance with design specifications and program requirements.

a.  Verify that contractors performing safety-related work have approved
    implementing procedures that describe administrative and procedural
    controls, approved work processes, and inspection requirements.

b.  Verify that procedures clearly prescribe acceptable methods of
    quality control inspection to ensure that the as-built condition
    meets specified design requirements, drawings and material
    specifications.

c.  Verify that procedures include appropriate quantitative and/or
    qualitative acceptance criteria for determining that the prescribed
    activities have been accomplished satisfactorily.

d.  Verify that equipment used for process monitoring, tests, and/or
    data collection is calibrated and maintained in accordance with
    approved calibration procedures and vendor requirements.

e.  Verify that procedures ensure that craft and quality control
    inspection personnel performing installation and testing activities
    are qualified to perform their work.

> [Guidance]{.underline}. The construction procedures should be
> reviewed, along with specifications, drawings and other design
> documents, to ensure that the work activities discussed in sections
> 02.02 through 02.06 below are being performed in compliance with the
> procedural controls and design details. The inspector should also
> review the quality control procedures, as well as applicable codes,
> standards and Regulatory Guides, to confirm that the licensee=s
> quality assurance is effective and complies with commitments.

02.02 [Foundation Work]{.underline}. Selection of an appropriate
foundation depends on the geotechnical characteristics of the underlying
soil or rock, groundwater conditions, and the foundation preparations.
The bearing capacity and settlement estimates will dictate the type of
foundation based on foundation loads and subsurface conditions.
Alternatives include foundations directly on soil or rock, and on
friction piles or bearing piles. For most nuclear power plant sites, an
excavation of existing soil or rock to competent material is typical.
This results in using compacted fills to ensure that the correct
elevation for the structure base is achieved. Although rock or pile
foundations may be used, the focus of this inspection is on engineered
backfill construction including the refilling of previously excavated
space with approved compacted material. Guidance for the inspection of
basemat related work activities is included in inspection procedure
65001.02 AInspections of ITAAC-Related Structural Concrete.@

a.  Backfill operations.

    1.  Verify that the specifications and design drawings define the
        type, characteristics, and compaction efforts of material to be
        used for backfill and that the licensee has controls in place
        for periodically verifying that the material meets the
        specifications.

    2.  Verify that the characteristics and type of compaction equipment
        used is as specified.

    3.  Verify that procedures define the maximum loose-lift
        thickness(typically six to twelve inches) for placement of
        backfill material and that ongoing quality control inspections
        verify conformance with this requirement.

    4.  Verify that the field density testing is performed by qualified
        testing personnel using the correct methodology and calibrated
        test equipment since backfill material characteristics can
        change during delivery and storage. Also verify that current
        proctor test results accurately reflect the material being
        placed. Changes in backfill material may require new proctor
        laboratory testing even though the material still meets design
        specifications.

    5.  Verify that the frequency and location of the quality acceptance
        in-place density tests is specified and adhered to.

b.  Rock foundations.

```{=html}
<!-- -->
```
1.  Verify that the soundness of the exposed rock is checked and
    determined to be solid and in an unfractured condition by qualified
    personnel.

2.  Ensure that if the removal of rock below foundation level is
    required, the resulting excavation is backfilled in a controlled
    manner with approved materials.

```{=html}
<!-- -->
```
c.  Pile foundations.

> Verify that the installation of piles is supervised by qualified
> personnel and that the driving resistance of the piles and a specified
> pile load test are used to verify the design capacity.
>
> [Guidance]{.underline}. Experience has shown that the most severe
> deficiencies in foundation work occur because of improper backfilling
> procedures and inadequate construction control. These include:
> allowing lift thicknesses that are inconsistent with equipment
> capabilities and thicker than allowed by the specifications; failing
> to require that the fill be built up uniformly in a well-defined
> pattern; placing backfill in adverse weather; and failing to perform
> sufficient field density testing in all areas. It is therefore
> important to observe backfill placement activities to ensure that work
> is being accomplished in accordance with design requirements.
> In-process testing, including in-situ testing, should also be observed
> to ensure that acceptable compaction prior to placement of subsequent
> lifts is being controlled by qualified personnel and that appropriate
> records are being reviewed and approved by cognizant engineers.

02.03 [Key Site Parameters]{.underline}. Review the key site parameters
that are specified for the design of safety-related aspects of
structures, systems, and components in the applicable Design Control
Document (DCD). Verify that the existing site foundation characteristics
fall within the design parameters.

Verify that the required values for average allowable static bearing
capacity and maximum allowable dynamic bearing capacity for normal plus
safe shutdown earthquake, typically expressed in pounds per square foot,
have been met at the excavation depth.

[Guidance]{.underline}. Due to the difficulties in performing work on
completed foundations and in conducting effective post‑­installation
foundation inspections, measuring existing site soil parameters
accurately is critical. Consideration should be given to performing
these first inspection activities with a Civil Engineer as the lead
inspector. As part of this inspection, the engineering design features
and programmatic controls for foundation work should be reviewed.
Consideration should be given to the possible effects from groundwater
intrusion and weather on the foundation preparation. Adequate drainage
control measures should be established to ensure that the exposed
surface will not be degraded by water accumulation.

02.04 [Key Dimensions and Volumes]{.underline}. Review the appropriate
dimensions and volumes listed in the Design Control Document that are
associated with the ITAAC selected for inspection. Once the key
dimensions have been identified, assess the method and controls the
licensee used to verify that the as-built dimensions conformed to the
DCD, specifications, drawings, and requirements. Verify that appropriate
records document that the completed work meets the design specifications
and acceptance criteria.

a.  Verify that measuring and surveying activities and associated
    calculations are conducted in accordance with the licensee=s quality
    assurance program requirements.

b.  Verify that surveying and measuring equipment is properly
    maintained, calibrated, or certified by a qualified M&TE program.
    Refer to Inspection Procedure 65001.C Construction Testing for
    additional guidance.

c.  Verify that personnel performing surveys or measurements are
    qualified and knowledgeable.

> [Guidance]{.underline}: Independent measurements by the inspector are
> not required by this procedure. Therefore, this inspection must ensure
> that the licensee has adequate controls in place to ensure that
> dimensional requirements have been met. If possible, observation of
> field measurements should be conducted to verify that work is being
> performed in accordance with appropriate procedures. The observation
> of field crews recording data should ensure that they are verifying
> daily logs for accuracy and systematically assuring that the
> construction layout conforms to plans. A review of field data should
> also be conducted to ensure that it is being correctly translated into
> permanent records. Ensure that any identified deviations are
> documented in accordance with the licensee\'s quality assurance
> program.

02.05 [Steel Structures]{.underline}. Fabrication and erection of steel
structures activities should be inspected to provide verification and
general construction quality and performance. This inspection will
assess the adequacy and effectiveness of procurement, implementing
procedures, qualification of personnel, ongoing construction activities,
and records.

a.  Select a sample of procurement documents for structural steel and
    verify the following:

    1.  The shape, size, dimensions, type, and grade of material conform
        to the approved specifications and design drawings.

    2.  Certified mill test reports or a certified report of tests made
        by the fabricator or qualified testing laboratory are available.

    3.  Verify by direct inspection that the items on-site are what was
        ordered by

procurement.

b.  Verify that process controls ensure the following:

    1.  An adequate marking system is used to maintain the identity of
        material from storage to installation.

    2.  Structural steel is protected from corrosion caused by exposure
        to weather, and that corrosion limits match design criteria.
        Refer to design drawing or specifications for governing codes
        for the site in question.

    3.  Nonconforming material is adequately identified and segregated.

c.  Verify the following construction attributes as they relate to the
    accepted design:

    1.  Fit-up tolerances for length, depth, and straightness of
        structural members and bolt holes are as specified.

    2.  Base plate elevations and degree of levelness as well as limits
        for contact bearing for column compression joints are as
        specified.

    3.  Finish for column bases and for thermally cut edges are as
        specified.

d.  Verify that the following attributes are as specified for anchor
    bolts, embedded weldments, and anchor plates:

    1.  Minimum concrete edge distance for bolts, studs, or bars with
        shear loading is as specified.

    2.  Concrete expansion anchor testing is as required.

    3.  Maximum and minimum edge distance for slotted, oversize, and
        standard bolt holes is as specified.

    4.  Maximum and minimum hole size for standard, oversize, short
        slotted, and long slotted holes for bolted connections is as
        specified.

    5.  Minimum spacing requirements for bolt holes are as specified.

    6.  Calibration of torque wrenches is as specified.

    7.  Tightening and tensioning of normal or high-strength bolts is as
        specified and the minimum thread engagement is also as
        specified. Bolt tension may be accomplished by using load
        indicating washers, torque wrenches or turn-of-the -nut method.

    8.  For cast-in-place anchors, the critical items shall be as
        specified. These include anchor size, material, length,
        embedment detail, length of embedment, projection above
        concrete, thread lengths, sleeve types, sleeve, sizes, sleeve
        lengths, and grouting requirements.

e.  For structural steel welding, refer to IP 65001.B for inspection
    attributes, and verify that procedures adequately address the
    following:

    1.  The identification of welds and welders is maintained for each
        weld.

    2.  Welding procedures and welders are qualified in accordance with
        the American Welding Society requirements for structural steel
        welding, and other codes or standards referenced by the product
        specifications.

    3.  Welding material and processes are adequately controlled as
        specified and referenced in Inspection Procedure 65001.B.

    4.  Nondestructive examination methods and acceptance criteria are
        as specified. Procedures specify the minimum visual examination
        of weld length requirements and the required inspection sampling
        for full-penetration and partial-penetration welds.

f.  Verify that foreign material exclusion (FME) controls are
    appropriately utilized as specified.

> [Guidance]{.underline}. Before work observation is performed, review
> the procedures and standards that apply to ensure familiarity with the
> requirements and acceptance criteria. Receipt inspection reports
> should be reviewed to verify material conformance. Steel should be
> inspected for damage and quality of fabrication prior to erection. The
> nature and extent of any damage that may have occurred because of
> loading, transit or unloading should be noted along with the
> identifying piece mark and entered into the corrective action program
> for proper assessment and disposition. Structural steel stored on the
> site should be supported off the ground on blocking. After receipt,
> markings should be used to indicate that the steel is accepted
> material and that fabrication has been properly performed.
>
> Erection methods should not impart damage to any member. Members must
> have their ends brought together at the correct relative elevation and
> held in correct alignment so that heavy drifting is not necessary to
> align the bolt holes. Sufficient drift pins must be installed to
> obtain accurate alignment of parts and a sufficient number of bolts
> must be used to compact the joint before members are released and
> allowed to deflect. As a rule of thumb, at least 50 percent of the
> holes must be filled with pins and snug-tight bolts. Due to the
> possibility of damaging the threads on bolts, any bolts installed
> prior to installing the drift pins shall be replaced. Drift pins
> should be cylindrical and not more than 1/32 inch smaller than the
> diameter of the hole.
>
> Tightening of bolts by the turn-of-the-nut method requires three
> separate steps: tightening to a snug-tight condition, match marking
> the protruding end of the bolt and adjacent surface of the nut and
> tightening the nut the additional specified rotation. Ensure that the
> match marks are correctly placed so that the relative rotation of the
> nut to the bolt is measured and not relative to the steel member or
> splice plate. The subsequent inspection of bolted joints should
> involve a torque wrench and a recently calibrated tension testing
> device. Torque wrenches should be calibrated at the beginning of each
> day of use and for each diameter or length of bolt being tested.
>
> During the welding of structural steel, care must be taken to prevent
> moisture in the atmosphere from being absorbed by the electrodes which
> can potentially cause cracking of the weld. Care must therefore be
> taken to abide by time and temperature restrictions for electrode
> usage. When ambient weather conditions result in temperatures lower
> than 50F, the base metal must be preheated prior to welding for
> materials up to 3/4 inches thick. Thicker materials will require even
> higher ambient temperatures. Further guidance to ensure welding
> material and processes are adequately controlled can be found in
> Inspection Procedure 65001.B.

02.06 [Records]{.underline}. Verify that records related to inspected
activities are reviewed for accuracy and that the recorded information
meets project requirements, DCD specifications, and ITAAC. Verify that
they are approved, and are correctly stored and maintained in such a
manner as to demonstrate conformance with design and procedure
requirements.

[Guidance]{.underline}: Select a sample of records for review. Verify
that the records were properly reviewed and approved in the responsible
organization. Records of the qualification of craft and quality control
personnel associated with the activity should also be reviewed.

02.07 [Identification and Resolution of Problems]{.underline}.

Verify that the licensee is identifying problems at an appropriate
threshold and entering them into the corrective action program.
