GEOTECHNICAL/FOUNDATION ACTIVITIES

PROGRAM APPLICABILITY: 2630

88131-01 INSPECTION OBJECTIVES

01.01 To determine whether the technical requirements detailed or referenced in the

Construction Authorization Request (CAR), the U.S. Nuclear Regulatory Commission,

Safety Evaluation Report (SER), and the approved-Mixed-Oxide Project Quality Assurance

Plan (MPQAP), associated with the baseline design criteria and geotechnical/foundation

construction and quality control for Seismic Category I (SC-I) and SC-II structures, have

been adequately addressed in the licensee and/or contractor construction specifications,

drawings, and work procedures, and whether the established system of management

controls is adequate.

01.02 To determine whether QA plans, instructions, and procedures for

geotechnical/foundation activities have been established in the facility QA manual and QA

implementing procedures.

01.03 To determine by direct observation and independent evaluation, whether work and

inspection performance relative to geotechnical/foundation activities are being accomplished

in accordance with the design specifications, drawings, and procedures.

01.04 To determine whether the licensee system for preparing, reviewing, and maintaining

records relative to geotechnical/foundation activities is functioning properly, and to

determine whether the records reflect work accomplishment consistent with specifications

and procedures.

01.05 To determine, by direct observation of work activities and review of records, whether

inadequacies in work activities associated with geotechnical/foundation activities indicate

any potentially generic problems, management control inadequacies, or other weaknesses

that could have safety significance.

88131-02 INSPECTION REQUIREMENTS

02.01 For each onsite organization with QA and/or Quality Control (QC) responsibilities

relative to geotechnical/foundation activities, the inspector should refer to the appropriate

Mixed Oxide Fuel Fabrication Facility QA inspection procedures. If there are multiple

contractors with QA/QC responsibilities in this area, inspect a sample, using engineering

judgment, concerning the safety significance and the complexity of each work activity.

02.02 Review the construction specifications related to geotechnical activities and

ascertain whether the specified technical requirements conform to the commitments

contained in the CAR. Determine whether appropriate and adequate procedures in the
88131 - 2 - Issue Date: 10/25/06

following areas are compatible with the QA program and prescribe adequate methods to

meet the construction specifications, where applicable.

a. Excavation and subgrade preparation.

b. Foundation verification.

c. Placement of engineered fill and backfilling.

d. Dewatering.

e. QC inspection and testing.

f. Instrumentation and settlement monitoring.

g. Surveying.

h. Engineering direction.

I. Soil compaction and testing

02.03 If applicable to the project, perform a review of the results of the test-fill program,

before reviewing the implementing construction procedures, to verify that the fill procedures

have been qualified. The implementing procedures should reflect the methods, equipment,

materials, and conditions of the test-fill program.

02.04 Determine whether the licensee has an established audit program (including plans,

procedures, and audit schedule) for assessing the adequacy of SC-I and SC-II work control

functions, in the area of geotechnical/foundation activities, and for ensuring that

examination, inspection, and test personnel associated with performing tests and

inspections of geotechnical/foundation activities are qualified and/or certified to perform their

assigned work.

02.05 By direct observation of work in progress on the material supporting SC-I and SC-II

structures, ascertain whether the following applicable geotechnical/foundation activities are

being controlled and accomplished in accordance with the requirements of the documents

reviewed in 02.02, above:

a. Excavation and Subgrade Preparation. The following items should be verified when

inspecting the excavation, and preparation of the foundation subgrade.

1. The excavation methods and sequence of operations should not be

detrimental to the final foundation subgrade materials.

2. Unusual or changed conditions encountered during excavation of cavities,

faults, pockets of unsuitable material, springs, seeps, boils, and protrusions,

are noted, investigated, evaluated, and taken into consideration.

3. The foundation subgrade should be free of organic or soft unsuitable material.

Depressions or holes left by grubbing and stripping or excavation should be

backfilled with suitable materials compacted and tested to the specified

density and moisture content. Soil classification at the depth excavated for

foundations should be verified and compared with the soil profile determined

during subgrade explorations (bore holes, exploratory excavations, etc.). The

occurrence of extraneous detrimental or unexpected soil may necessitate

further investigation or evaluation/redesign. The finished grade should be

as specified, meet compaction and density requirements, be protected from

the elements, and be tested and inspected.

4. Determine whether the stockpiling and segregation of excavated materials

which are to be used as SC-I fill material are in accordance with

specifications.
Issue Date: 10/25/06 - 3 - 88131

5. The foundation subgrade treatment such as compaction, installation of

foundation drains, or other methods should be properly controlled.

6. Determine whether QC inspections are adequate with regard to scope,

frequency, and inspector qualifications.

7. The record-keeping activities should reflect the actual conditions encountered

in the field and provide adequate documentation of work and inspections.

Determine whether records are being maintained, reviewed, and approved

as specified.

b. Foundation Verification.

Verify that geotechnical engineering direction is available. Foundation subgrades

should be approved by an experienced geotechnical engineer before placement

of engineered fill, mudmats, or structural concrete. Determine whether records are

maintained to document approval of the final foundation subgrade. Records should

include elevation, actual conditions, methods to achieve acceptable conditions, and

inspection and test acceptance criteria and final acceptance results. 

c. Backfilling (Fill Materials and Compaction Control). At least quarterly while backfill,

engineered fill, or compaction activities are in progress, ascertain that:

1. Specified lift thicknesses are adhered to and specified equipment is being

used with the correct number of roller passes.

2. Source material being used is identified and is traceable to an approved

borrow source. The approved source material should meet design and

earthwork specification requirements and have been properly qualified by an

approved soils laboratory.

3. Ensure that engineered fill or backfill is placed at the proper location and on

approved foundation materials.

4. Verify that in-place density tests are being performed at the required

frequency with properly calibrated instruments (including moisture content

tests). If a nuclear density test is performed using a nuclear density gauge

or Troxler, verify that the instrument has been calibrated and radioactive

source leak checks have been performed.

5. Samples for laboratory tests are being taken at the required frequency, chainof-custody established, and the samples are adequately identified. Review

the results of the required tests and compare results to design specification

requirements and applicable standards.

6. Inspection activities (QA and QC) are being performed as required by

qualified and/or certified personnel. Review inspection documentation and

verify that the records quantitatively define actual construction conditions and

QC qualitative test results.

d. Dewatering Systems. The following items should be reviewed (permanent,

important-to-safety dewatering systems will necessitate a more extensive review).

Note that 1 and 2, below, represent good practice, but are not requirements unless

specified in the site specifications.
88131 - 4 - Issue Date: 10/25/06

1. Emergency power supply to ensure continuous dewatering system operation

is being maintained and tested.

2. Open excavations are protected from flooding by an adequate sump pump

system.

3. Piezometric surfaces are being defined by monitoring performed at the

required frequency.

4. Inspection and testing of system discharge should assure that sediment

material is not being removed from the foundation.

e. QCl Inspection and Onsite Testing Laboratory. The onsite laboratory should be

inspected while tests are being performed on SC I material. The following items

should be verified during the inspection:

1. The onsite laboratory has performed verification of laboratory personnel

qualifications (education and experience) of testing and inspection personnel.

Personnel qualification verifications must be supported by objective evidence

documenting education and experience.

2. Test results are being evaluated at an appropriate level and evaluation

includes trend analysis.

3. Observed testing standards conforms to the procedures specified in the

American Society for Testing and Materials.

4. Testing apparatuses are calibrated at the required frequency and calibration

traceable to a nationally recognized standard and calibration is in accordance

with approved procedures.

5. Records reflect the results of inspections, the actual field conditions, testing

frequency requirements, acceptance criteria, and data calculations are

checked.

f. Instrumentation and Settlement-Monitoring Program. Review specific

instrumentation or settlement-monitoring programs. The following items should be

verified during the inspection:

1. Number, location, and type.

2. Instrumentation and settlement-monitoring systems installed before start of

activity being monitored.

3. Instrumentation and settlement-monitoring systems are installed as specified,

functioning properly, and protected against construction hazards.

4. Operation and monitoring: operations are monitored at specified frequency

to assure that construction activities have not made installed instrumentation

inoperable.

5. Calibration of measuring and testing equipment is maintained, logged and

functionally checked.

6. Recordkeeping activities: records reflect specified frequency of monitoring,

data checks (e.g., supervisory review, engineering review), data evaluated
Issue Date: 10/25/06 - 5 - 88131

and accepted. This is important in activities such as settlement monitoring.

A comparison of the actual settlement data with those predicted can reveal

problems at an early stage, enable the cause to be determined relatively early

in the construction phase, or can cause design changes to be incorporated

before the completion of extensive construction work.

g. Surveying. Surveying activities should be reviewed annually to assure that the

instruments are properly calibrated, and calculations are checked to assure

accurate results.

h. Engineering Direction. Verify that engineering direction is available onsite to

monitor geotechnical/foundation construction activities. The onsite engineering

staff should be supplemented by an experienced geotechnical engineer to approve

final foundation subgrade materials, monitor and review QC inspection and test

results, and identify changed field conditions. The onsite engineering staff should

be involved in disposition of nonconformance reports, and prepare engineering field

change requests for approval by the engineering design agent or organization. 

i. Personnel Interviews. Informal interviews with field-craft and inspection personnel

should be randomly conducted, to determine how well employees know the

requirements of their work activity. Also, obtain a sense of the degree of

adversarial or intimidating relationships that may exist with the construction forces.

Perceived management support should be identified. Any adverse trend should

be identified to regional management. Ascertain whether a sufficient number of

adequately qualified QA and inspection (QC) personnel are at the construction site,

commensurate with the work in progress, and adequately performing their assigned

duties through the established organizational structure.

02.06 Review the documentation generated for the geotechnical/foundation activities.

Determine whether the licensee/contractor system for documenting safety-related work is

functioning properly. Records should be legible, complete, reviewed by QC and/or

engineering personnel, and readily retrievable. Review a sample of the following records:

a. Receipt Inspection and Material Certification (if applicable). Applicable for materials

purchased from offsite suppliers such as drainage materials, geosynthetic fabrics,

select fill materials, sand and gravel, instrumentation, and dewatering system

components. Records confirm that required material characteristics, performance

tests, civil soil tests, nondestructive tests, and other earthwork specification

requirements were met.

b. Installation Inspection. Records confirm that specified materials and components

were installed as specified and that the required inspections were performed and

acceptance criteria are defined.

c. Nonconformance/Deviation Record. Records include current status of these items.

Nonconformance reports include the status of corrective action or resolution,( e.g.,

determine whether adequate corrective action is being taken when moisture density

test results are not within tolerance or acceptance criteria.

d. Training/Qualification Records of Craft, QA, and Inspection (QC) Personnel.

Records establish that QA/QC personnel are adequately qualified for their assigned

duties and responsibilities and that craft personnel have been trained in their

assigned tasks.
88131 - 6 - Issue Date: 10/25/06

e. QA Audits. Records establish that the required audits were performed and that

deficiencies identified during audits were corrected, and that corrective action was

such that repetition of the deficiency, or similar deficiencies, would be precluded.

88131-03 INSPECTION GUIDANCE

General Guidance. Applicable portions of the CAR, the SER, and approved QA plan should

be reviewed to determine licensee commitments relative to construction and inspection

requirements, before performing this inspection. The inspector should then use these

documents during the review of the construction specifications, drawings, work procedures,

and QA implementing procedures. Geotechnical/foundation activities should also be

reviewed in the light of being consistent with standard industry practice for the successful

completion of that activity.

Because earth structures involve unique construction processes for each project, the

number of geotechnical/foundation activities listed above, which should be reviewed,

depends on the significance and applicability of that activity with respect to site conditions

and the need for establishing a close relationship between the geotechnical design and the

construction techniques and related monitoring. It is for this reason that this inspection

module should be performed by someone who is able to discriminate between, and weigh

those activities that will require the most attention, and which will have the most impact on

safety. The inspector should use judgment in determining sample selection during

inspection activities. Sample selection should reflect the importance of the activity to safety.

Observations of work and independent verification of critical dimensions, locations, etc.

should be performed at various stages of completion, especially for engineered fill and

structural foundations. The inspector should be aware of the compaction and backfill

materials problems identified at several sites and described in IE Circular 81-08.

The licensee is responsible to implement or have implemented the approved QA program

and the commitments described in the CAR . The inspector must determine if this program

is implemented in an adequate and timely manner for the important-to-safety work in

progress. 

QA/QC procedures must provide for effective inspections that will ensure that work is

performed in accordance with specification requirements. QA audits should identify

procedural inadequacies and the root cause of repetitive nonconforming conditions.

Inspections should require verification of specified controls and should not be accomplished

merely by surveillance. Laboratory and field testing procedures must provide for verification

of correct material usage, correct selection of reference standards, and should prohibit

discretionary selection of inspection and testing parameters by the contractor or QC

personnel. Results of testing should be reviewed by qualified personnel and a

determination of acceptability of the results made. Construction procedures must reference

the required inspection hold points and must also address the QA/QC department stop-work

authority.

Findings from this inspection activity should address each element as being satisfactory,

being unresolved and requiring resolution, or being in violation and requiring correction.

When significant inadequacies are identified, in the specifications or procedures, indicating

weakness within the preparing organization, the inspector should inform cognizant regional

management. The issue should be addressed at the appropriate level of licensee

management.

03.01 Specific Guidance

Note: The numbering of the guidance below refers to specific subsections of 02, above.
Issue Date: 10/25/06 - 7 - 88131

02.01 The inspector should also review appropriate sections of American Society

of Mechanical Engineers (ASME) NQA-1-1994 Edition with NQA-1a-1995

Addenda, as they relate to Structural Concrete, Structural Steel, Soils and

Foundations for Nuclear Power Plants. Specific attention should also be

given to the QA program needs that may result from the distribution of design

and construction responsibilities. Examples of these needs may be:

provisions for adequate onsite engineering direction, appropriate and

adequate procedures related to procurement and use of materials, and

adequate control of hold points.

02.02 The construction specifications must translate design requirements with

sufficient detail to define the acceptance testing requirements and should

specify the personnel and interface responsibilities required to define, control

and resolve field or design geotechnical/foundation problems that are

evidenced during construction. The specifications must also provide for

qualifications of the equipment and techniques to be used to meet the

specification requirements for compaction of soils. The specifications should

provide for control of design changes and the issuance of design change

notices.

02.02a Generally, procedures for the removal of material (excavation) are not

required, but the condition of the underlying soil must be prepared/retained

as specified. 

02.02b Procedures should provide for approval of foundation elevation (soil subgrade

material), by an experienced geotechnical engineer, before placement of

engineered fill, mudmats, or structural concrete. The procedures should

specify appropriate sampling and testing procedures to verify the foundation

material in place is as specified in the design documents.

02.02c Selection and compaction of fill material is not always considered an

important activity by some construction contractors. Attention should be

given to the adequacy of compaction procedures and inspection (QC)

procedures to ascertain whether fill placement meets applicable

requirements. Continuous inspection by QC inspectors will be required during

fill placement operations.

02.02e Procedures for settlement monitoring should provide for settlement survey

accuracy, review of data, establishment of settlement points/monuments, and

establishment of bench marks for vertical control, such that they are

unaffected by groundwater levels and construction activities.

02.02f Site-surveying activities are one of the fundamental jobs done during

construction, but do not receive much attention. Surveying activities include

layout, settlement monitoring, and dimensional verification of structures,

components, or equipment.

02.05b Determine whether a geotechnical engineer is available to inspect and

monitor excavation and fill-placement activities. Final approval of

foundation/soil subgrades, by a qualified geotechnical engineer, is required,

before placement of engineered fill, mudmats, or structural concrete.

Approval needs to be based on appropriate sampling and testing procedures

to verify the foundation material in place is as specified in the design

documents.
88131 - 8 - Issue Date: 10/25/06

02.05c2 If select fill is used, the inspector should determine, before use, whether the

materials satisfy the prescribed gradation specifications and tests.

02.05c4 By a selective review of test results, the inspector should determine whether

adequate corrective action is being taken, when density, or moisture test

results, are not within acceptance criteria.

02.05d The inspector should be aware that the design of the dewatering system may

have to be modified when excavation or testing identify such a need, more

pumping capacity may be required after evaluation of existing conditions.

02.05e.1 In determining the adequacy of QA/QC staffing, the effectiveness of their

activities must be considered. Insufficient or unqualified personnel, or

inadequate QA management, indicate inadequate staffing. Capabilities and

effectiveness, rather than only the number of personnel, are the principal

criteria to be used.

02.05e.5 A sample of data calculations should be reviewed for accuracy and

conformance to design requirements.

02.05f Examples of typical instrumentation are monuments, for settlement

monitoring, and piezometers or well points, for monitoring groundwater

surface and pore pressure.

03.02 Prevalent Errors and Concerns. Prevalent errors and recent concerns are areas

in which the inspector should be alert to potential generic issues. These areas include:

a. Insufficient compaction of foundation and backfill materials was identified at several

sites, as described in IE Circular 81-08.

b. Placement of fill for control of compaction requires control of ground-water levels.

c. QC test results need to be reviewed and trended to assure that tests are performed

in accordance with specification requirements, that the results are reasonable, that

the results meet requirements, and that locations where samples/tests were

obtained (location and elevation) can be accurately identified. Test deficiencies

need to be entered into the corrective action program and evaluated by engineering

personnel.

d. QA audits should identify procedural inadequacies or the cause of repetitive

nonconforming conditions.

03.03 Background Information. This information is to be used as reference material;

however, the site specifications govern. The information may be valuable in discussions

about the adequacy of the specifications.

a. Foundation Subgrade

1. Excavation. Unexpected conditions are frequently encountered, ranging from

unfavorable deposits of materials not found in the exploratory program, to

problems not identified in previous site studies.

Where unfavorable conditions are encountered, further exploration by test

pits, borings, or other means are necessary to define the extent and nature

of conditions. The effect of the unexpected conditions must be evaluated in
Issue Date: 10/25/06 - 9 - 88131

relation to the original design. Examples of common unfavorable conditions

frequently encountered are:

- Highly compressible and low-strength soils;

- Collapsible soils - low-density soils that collapse when saturated;

- Old river channels;

- Cavities and solution features;

- Overhangs and surface depressions;

- Springs or artesian conditions; and

- Unstable excavation slopes because of unanticipated conditions.

Excavation materials are frequently used as engineered fill or backfill around

and under SC-I and SC-II structures. The inspector should determine

whether these materials have been qualified through explorations and testing

by a soils testing laboratory and whether they are stockpiled in designated

areas. Excavated materials to be used as SC-I and SC-II structural fill,

should be excavated in layers, so that widely varying soil classes are not

mixed. Some of the more common tests used for qualifying soils materials,

and their associated standards, are:

- Moisture/density relationships, ASTM D-698 or D-1557;

- Soil-classification tests, ASTM D-2487;

- Particle-size analysis, ASTM D-422;

- Test for plastic limit and plasticity index, ASTM D-424; and

S Other Codes and Standards, as listed in ASME NQA-1.

A geotechnical engineer should control acceptance and qualification of

excavated materials.

b. Foundation Verification - Undisturbed Soil. A geotechnical engineer should

approve soil subgrades before placement of engineered fill, mudmats, or structural

concrete. Compaction is the usual method to treat or stabilize loose, disturbed, or

unsuitable areas in soil subgrades. The inspector should determine whether

appropriate sampling and testing procedures are included to verify the material in

place is as specified. Common tests used to verify that foundation subgrades meet

design specifications are listed in Appendix B, “Methods of Subsurface Exploration”,

of Regulatory Guide 1.132, “Site Investigations for Foundations of Nuclear Power

Plants.”

b. Backfilling. In some instances, preparation for foundations may consist merely of

excavation and grading to appropriate dimensions. However, in many locations,

the top layer of native site material may be too soft, or otherwise unsuitable, to

properly support the structures. In this case, some special compactive effort may

be required. Occasionally, adequate compaction may be achieved on the native

material in place in conjunction with careful control of groundwater level. More

typically, it will be necessary to remove the native material and fill the resultant
88131 - 10 - Issue Date: 10/25/06

excavation under carefully controlled procedures, in relatively thin layers,

sequentially compacted.

Before placing engineered fills, materials and compaction requirements should be

qualified by laboratory tests and test fills. Required moisture/density relationships

for each material should be determined in accordance with either ASTM D-698 or

ASTM D-1557. The inspector should be assured that the specified method is being

used. Where impervious materials are used, qualification tests should include

determination of the Atterberg Limits (“Liquid Limit, Plastic Limit and Plasticity

Index”, ASTM D-4318). Particle-size analysis should also be made, as specified

by test methods in ASTM D-422 and ASTM D-1140.

Test fills for each material type should be made to determine lift thickness, type of

compaction equipment, and number of passes to be used in compacting fills to

specified densities.

In-process testing used to control fill placement, for the most part, will be density

tests and moisture tests. Acceptance will be in terms of some percentage of the

maximum dry density (usually 95 percent) and a moisture content within some

percentage of optimum (usually ±2 percent) as determined by ASTM D-698 or

ASTM D-1557. Density tests may be made by test methods ASTM D-1556 (most

common method used); ASTM D-2167; ASTM D-2922, or ASTM D-2937. Testmethod ASTM D-2922, the nuclear method, must be calibrated against a reliable

direct method. 

Control of moisture content at time of compaction is extremely important, especially

with materials having more than 12 percent passing a No. 200 sieve. Testing and

research has demonstrated that variation of the moisture content of a material, at

time of compaction, even though it has been compacted to the same dry density,

has a wide-ranging effect on the shear strength, permeability, and consolidation

characteristics of the material. Ultimate control of moisture should be by testmethod ASTM D-2216, “Laboratory Determination of Moisture Content of Soil”.

Rapid methods, such as the "Speedie" and field stoves, are sometimes used to

expedite operations, because of the time required for test-method ASTM D-2216.

Where rapid methods are used, they should be calibrated against ASTM D-2216,

and their variation taken into consideration in controlling moisture content of the

fill. For example, if the specified moisture control is ±2 percent of optimum and

calibration checks show that the rapid method varies by ±1 percent from ASTM

D-2216, then field control using the rapid method should be held to ±1 percent of

optimum. Field-stove methods should be limited to granular materials, with little

or no fines, since experience shows results with impervious materials are erratic

(probably because of driving off the water of hydration).

Minimum acceptable test frequencies and other recommended in-process testing

controls are listed in Table 5.6 of ASME NQA-1 Subpart 2.5.

d. Dewatering Systems. Some degree of groundwater control will be required, at least

during site preparation and foundation placement. Groundwater removal may be

required to properly compact the soil-bearing area. The design may require that

groundwater be permanently maintained below some specified elevation.

Excavations and placement of fill and foundations must be in the dry state.

Discharge outlets of dewatering systems should be monitored for sediment content,

to assure that subgrades are not being undermined. Dewatering systems, if not

properly designed, installed, and operated, can have an adverse effect on

foundations. Improper design and operation can and have resulted in undermining
Issue Date: 10/25/06 - 11 - 88131

of foundations through removal of sediment with the discharge water. The

inspector should assure himself that careful consideration has been given to the

impact that the installation, operation, shutting down, and decommissioning of the

system will have on foundation design. Through observations, the inspector should

satisfy himself that the system has been installed and is being monitored as

specified. Piezometers or observation wells should be used in conjunction with the

dewatering system, to monitor the groundwater surface and pore pressure beneath

the subgrade and adjacent ground.

Acceptable methods for installation and maintenance of piezometers and

observation wells are presented in the U.S. Army Corps of Engineers Manual, EM

1110-2-1908, 1972.

e. Testing Laboratory. Acceptance of all earthwork onsite, including verification of

soil foundations, engineered fill and backfill, for the most part, will be based on

testing done by the site-soil laboratory. The inspector should routinely check the

soils laboratory during inspections. The inspector should ensure that work is being

done in accordance with specified methods and with specified equipment that is

periodically calibrated for accuracy. Testing personnel should check data

calculations for accuracy and the inspector should spot check them.

Qualifications of testing personnel should be checked by personal interviews,

examination of certification records, and licensee's procedures and records, to

verify contractor's qualification records.

f. Instrumentation- and Settlement-Monitoring Programs. Instrumentation will, for the

most part, consist of settlement monuments for monitoring settlement and

piezometers, or well points for monitoring the groundwater surface and pore

pressure. Specific guidance regarding their use, installation, and maintenance is

presented in the U.S. Army Corps of Engineers Manual EM 1110-2-1908. The

inspector should ensure that the instrumentation is installed as specified, is

adequate for the intended use, and that accuracy of the data recorded is sufficient

to provide needed information. The instruments should be monitored periodically,

throughout construction, and, if needed, post-construction.

88131-04 RESOURCE ESTIMATE

This inspection procedure is expected to take, on the average, 24 to 32 hours for each

review of licensee/contractor activities. The procedure should be run once during the early

excavation and preparation for SC-1 structures, and additional inspections should be

conducted during any back-fill operations that could significantly affect SC-I or SC-II

structures. Regional Management should use inspector observations, concerning the

relative complexity of required SC-I foundation work, and observed competency of licensee

and contractor personnel, to schedule additional inspections as required.
