Purpose and Scope
| The | purpose | of | this | study | was | to | investigate | subsurface | conditions | at | the | location | of | the | proposed |
| structures, | to | provide | geotechnical | engineering | recommendations | for | foundation | design, | subgrade | ||||||
| preparation | and | construction | considerations, | as | required | for | the | structures, | based | on | the | information | |||
| provided | for | the | development | of | the | scope | provided | in | our | proposal | dated | March | 20, | 2013. | |
| Specifically, | the | scope | of | work | included | the | following: |
| Review | existing | information | to | assist | in | developing | a | subsurface | exploration | program | for | the |
| proposed | structure. |
| Conduct | a | subsurface | exploration | program | consisting | of | one | (1) | test | boring | within | the | footprint | of |
| the | structure | to | evaluate | subsurface | conditions | and | obtain | soil | samples | for | laboratory | testing; |
| Conduct | laboratory | tests | on | select | soil | samples | to | assist | with | classification | of | soils | encountered | and |
| determine | engineering | properties; |
Perform engineering analysis and evaluations;
| Develop | foundation | engineering | recommendations | for | foundation | design | and | construction | of | the |
| Munitions | M | & | I | Facility; | and |
| Prepare | this | memorandum | presenting | CDM | Smiths' | recommendations, | including | data | collected | as |
| part | of | the | investigations. |
Subsurface Exploration Programs
| CDM | Smith | subcontracted | Geo‐Environmental | Drilling | Company, | Inc. | of | Pittsburgh, | Pennsylvania | to | |||
| complete | one | (1) | test | boring | (CDM‐1) | to | investigate | the | subsurface | conditions. | The | exploration | was |
| completed | on | July | 9, | 2013. |
01 01 00a - 2

| The | test | boring | was | drilled | using | a | CME‐55 | truck | mounted | drill | rig. | The | test | boring | was | drilled | to | a |
| depth | of | about | 8 | feet | below | ground | surface | (bgs) | using | 2‐1/4‐inch | inside | diameter | (I.D.) | hollow | stem | |||
| augers | (HSA). |
| Standard | Penetration | Test | (SPT) | were | performed | in | accordance | with | ASTM | D‐1586 | (using | a | 2‐inch | ||
| outside‐diameter | sampler | driven | 18 | inches | by | blows | from | a | 140‐pound | safety | hammer | falling | freely | ||
| for | 30‐inches). | The | number | of | blows | required | to | drive | the | sampler | each | 6‐inch | increment | was | |
| recorded | and | the | Standard | Penetration | Resistance | (SPT | N‐value) | was | determined | as | the | sum | of | the | |
| blows | over | the | last | 12 | inches | of | penetration. | When | a | refusal | condition | was | encountered, | the | number |
| of | blows | with | the | corresponding | depth | of | penetration | was | recorded. | Refusal | is | defined | as | more | than |
| 100 | blows | over | less | 6 | inches | of | penetration. | Split | spoon | sampling | was | typically | conducted |
continuously.
| A | CDM | Smith | representative | visually | classified | the | soil | samples | recovered | in | the | field | in | accordance |
| with | the | Burmister | classification | system. | Representative | soil | samples | from | each | split | spoon | were | ||
| collected | and | stored | in | jars | for | subsequent | review | and | geotechnical | laboratory | testing. | All | samples | |
| were | labeled | with | the | boring | number, | sample | number, | depths, | sample | interval, | recovery, | and | date | |
| using | indelible | ink. |
| The | groundwater | level | at | the | test | boring | was | measured | within | the | borehole | after | completion | of |
| drilling. | The | test | boring | was | backfilled | with | soil | cuttings | and | patched | after | completion. |
| The | test | boring | was | located | in | the | field | by | taping | and | line | of | sight | from | existing | site | features. | The |
| approximate | location | of | the | test | boring | is | shown | on | Figure | 1. | A | test | boring | log | is | included | in | |
| Attachment | A. |
Geotechnical Laboratory Testing
| Geotechnical | laboratory | testing | was | conducted | on | one | soil | sample | from | the | test | boring. | The | purpose |
| of | the | geotechnical | laboratory | testing | was | to | assist | with | soil | classification | and | characterization | of | |
| engineering | properties. | Geotechnical | laboratory | testing | was | performed | by | Geotechnics | of | Pittsburgh, | ||||
| Pennsylvania. | All | the | tests | were | performed | in | general | accordance | with | the | associated | ASTM | ||
| standards. | A | summary | of | the | geotechnical | laboratory | testing | results | are | presented | in | Table | 1. | |

Site Geology and Mine Subsidence Potential
| The | site | is | located | within | the | Pittsburgh | Low | Plateau | Section | of | the | Appalachian | Physiographic |
| Province. | The | Pittsburgh | Low | Plateau | is | generally | described | as | having | broad, | relatively | flat | anticlinal |
ridges.
| The | local | bedrock | underlying | the | site | belongs | to | the | Casselman | Formation | of | the | lower | Pennsylvanian | |||
| aged | Conemaugh | Group. | This | formation | is | characterized | by | cyclic | sequences | of | claystone, | sandstone, | |||||
| limestone, | shale, | and | non‐commercial | coal | seams. | A | review | of | the | Pennsylvania | Department | of | |||||
| Environmental | Protection | (DEP) | Mine | Subsidence | Insurance | Fund | indicated | no | previous | records | of | ||||||
| underground | coal | and/or | clay | mining | having | taken | place | in | the | direct | vicinity | of | the | site. | The | risk | for |
| mine | subsidence | at | the | site | is | considered | to | be | low. |
Subsurface Conditions
| The | subsurface | conditions | encountered | at | the | site | typically | consisted | of | Fill | underlain | by | Residual | Soil. |
| A | summary | of | subsurface | conditions | encountered | at | the | recent | subsurface | exploration | location | is | ||

| Fill | was | encountered | at | test | boring | CDM‐1. | The | fill | layer | was | 3 | feet | in | thickness | at | the | test | boring |
| location. | A | 6 | inch | thick | layer | of | asphalt | paving | with | a | 12 | inch | thick | layer | of | aggregate | base | was |
| encountered | at | the | ground | surface. | The | Fill | material | below | the | base | material | consisted | of | moist, | ||||
| medium | dense, | brown, | fine | to | coarse | SAND, | little | fine | to | coarse | gravel, | trace | silt, | trace | asphalt | pieces. | ||
| The | SPT | N‐Value | was | 11 | blows | per | foot | (bl/ft) | at | the | test | boring | location. |
Residual Soil
| Residual | Soil | was | encountered | at | test | boring | CDM‐1 | below | the | Fill | layer. | The | Residual | Soil | layer | was | ||||||
| greater | than | 5.1 | feet | in | thickness | at | the | test | boring | location. | The | Residual | Soil | layer | was | not | fully | |||||
| penetrated. | The | Residual | Soil | layer | was | comprised | of | a | decomposed | claystone | and | typically | consisted | |||||||||
| of | moist | to | dry, | very | stiff | to | hard, | dark | to | light | brown | to | gray, | CLAY | & | SILT, | trace | to | some | fine | to | coarse |
| sand, | trace | fine | gravel. | The | SPT | N‐Values | ranged | from | 23 | bl/ft | to | 100 | blows | per | 1 | inch | with | an | ||||
| average | N‐Value | of | greater | than | 100 | bl/ft | at | the | test | boring | location. |

Groundwater Conditions
| Groundwater | was | encountered | in | test | boring | CDM‐1. | The | water | level | measured | at | CDM‐1 | was | about |
| 2.5 | feet | bgs | after | completion | of | drilling. |
Variation in Subsurface Conditions
| The | interpretation | of | general | soil | conditions | presented | herein | is | based | on | soil | and | groundwater |
| conditions | observed | at | the | exploration | location. | However, | subsurface | conditions | may | vary | at | locations | |
| other | than | the | subsurface | exploration | location. |
| It | should | be | noted | that | the | proposed | location | of | the | Munitions | M | & | I | Facility | was | revised | from | the |
| original | planned | location | after | completion | of | the | subsurface | exploration | program. | If | conditions | found | ||||||
| at | the | revised | structure | location | are | different | from | those | assumed | based | on | the | exploration | program, | ||||
| recommendations | contained | in | this | memorandum | should | be | reevaluated | and | confirmed | in | writing. |
| Groundwater | levels | are | expected | to | fluctuate | with | time, | season, | temperature, | and | construction | ||||
| activities | in | the | area, | as | well | as | other | factors. | Therefore, | groundwater | conditions | at | the | time | of |
| construction | may | be | different | from | those | found | during | the | time | of | the | explorations. |
Geotechnical Engineering Evaluations and Design Recommendations Geotechnical Engineering Evaluations
| Geotechnical | engineering | evaluations | have | been | made | as | they | relate | to | the | proposed | Munitions | M | & | I |
| Facility | in | Moon | Township, | Pennsylvania. | In | general, | these | evaluations | have | been | based | on | the | results | |
| a | of | subsurface | investigation, | laboratory | test | results, | published | correlations | with | soil | properties | and | |||
| the | minimum | requirements | of | the | Pennsylvania | State | Building | Code | (Code) | and | subsequent | ||||
| amendments. | In | addition, | recommended | design | criteria | are | based | on | performance | tolerances, | such | as | |||
| allowable | settlement, | as | understood | to | relate | to | similar | structures. |
Design Recommendations Foundation Design
| The | proposed | Munitions | M | & | I | Facility | and | Glycol | Storage | Tank | Pad | should | be | supported | on | spread |
| footings | or | mat | foundations | bearing | on | a | minimum | 12‐inch | thick | layer | of | compacted | structural | fill. | ||
| The | structural | fill | layer | should | be | placed | directly | over | Residual | Soil | present | at | subgrade | level | or | |
| compacted | structural | fill | placed | after | the | removal | of | existing | unsuitable | soils. | Unsuitable | soils | present | |||
| at | the | subgrade | level | should | be | over | excavated | down | to | Residual | Soil | and | replaced | with | compacted | |
| structural | fill. | Unsuitable | soils | include | topsoil, | organic | soils, | existing | fill | or | any | other | soft, | loose | or | |
| disturbed | soil | present | at | the | foundation | subgrade | level. | The | subgrade | should | be | protected | and | |||
| prepared | in | accordance | with | the | recommendations | provided | below. |
| The | foundation | for | the | proposed | structures | may | be | designed | for | a | maximum | allowable | net | bearing | |||||
| pressure | of | 4,000 | pounds | per | square | foot | (psf). | The | least | lateral | dimension | (width) | of | foundation | |||||
| should | be | at | least | 3.0 | feet. | Where | the | structure | is | founded | on | structural | fill, | the | fill | should | extend | at |
01 01 00a - 5
| Keith | A. | Williams, | AIA, | PMP |
| October | 22, | 2013 | ||
| Page | 6 |
| least | 2.0 | feet | beyond | the | outer | edge | of | the | foundation, | then | outward | and | downward | at | as | slope | of | 1 |
| horizontal | to | 1 | vertical. | Structural | fill | should | be | compacted | to | at | least | 95 | percent | of | its | maximum | dry | |
| density | as | determined | by | ASTM | D1557. |
Foundation Depth
| In | accordance | with | the | Code, | all | foundations | supported | on | soil | should | bear | at | least | 3.5 | feet | below | any |
| adjacent | ground | surface | exposed | to | freezing. | Interior | footings | within | heated | portions | of | the | structures | ||||
| should | bear | at | least | 12 | inches | below | any | adjacent | ground | surface. |
Lowest Level Floor Slab
| The | lowest | level | slab | may | be | designed | as | a | mat | bearing | on | a | minimum | of | 12‐inch | thick | layer | of |
| compacted | structural | fill. | The | structural | fill | layer | should | be | placed | after | the | removal | of | unsuitable | ||||
| soils. | Unsuitable | soils | include | topsoil, | organic | soils, | existing | fill, | or | any | other | soft, | loose | or | disturbed | |||
| soil | present | at | the | foundation | subgrade | level. |
Estimated Foundation Settlement
| Settlement | of | the | proposed | structure | designed | as | recommended | herein, | is | expected | to | be | less | than | 1 |
| inch | with | 0.5 | inches | of | differential | settlement. |
Earthquake Considerations
| For | the | purpose | of | determining | design | earthquake | forces, | Site | Class | “C” | should | be | used. | Therefore, | the |
| spectral | accelerations | should | be | modified | for | the | respective | site | class | when | determining | the | design | ||
| earthquake | response | accelerations | and | seismic | design | category | for | the | seismic | analysis | at | the | site. |
| Based | on | the | subsurface | investigation, | the | soils | encountered | at | the | site | are | not | considered | susceptible |
| to | liquefaction. |
Design Groundwater Elevation
| We | understand | that | the | proposed | structures | will | be | outside | the | 100‐year | base | flood | zone. | The | ||||
| groundwater | level | observed | in | the | test | boring | was | 2.5 | feet | bgs | at | the | time | of | drilling | (July | 2013). | For |
| the | purpose | of | design, | based | on | the | water | levels | observed | in | the | test | boring, | we | recommend | that | ||
| finished | grade | be | used | as | the | used | as | the | design | groundwater | level. |
Resistance to Buoyancy
| Any | portion | of | the | proposed | structure | that | extends | below | the | design | ground | water | level | should | be | |
| designed | to | resist | hydrostatic | pressures | from | the | design | groundwater | level | referenced | above | using | ||||
| the | dead | weight | of | the | structure | plus | weight | for | fill | placed | directly | over | extension | to | the | structure |
| foundations. | For | purposes | of | design | against | uplift, | the | material | used | as | backfill | should | be | assumed | to | |
| have | a | total | unit | weight, | in | place, | of | 120 | pcf. |

Lateral Pressure on Below‐Grade Walls
Resistance to Unbalanced Lateral Loads
| Unbalanced | lateral | loads | should | be | designed | to | be | resisted | by | friction | on | the | bottom | of | the | foundation. | ||
| For | purposes | of | design, | a | coefficient | of | friction | of | 0.35 | should | be | used. | It | is | expected | that | the | available |
| friction | will | be | sufficient | to | resist | all | unbalanced | lateral | loads. | However, | should | lateral | loads | exceed | ||||
| the | friction | available, | the | surplus | loads | may | be | resisted | by | passive | pressures | on | the | foundations, | ||||
| provided | the | walls/beams | are | appropriately | designed | for | the | pressures. | A | passive | pressure | resistance | ||||||
| of | up | to | a | maximum | equivalent | fluid | pressure | of | 150 | pcf | may | be | assumed | provided | the | foundations | ||
| walls | are | backfilled | with | structural | fill | compacted | to | a | density | of | at | least | 95 | percent | of | the | maximum | |
| dry | density | as | determined | by | laboratory | test | ASTM | D1557. | The | resistance | from | the | upper | 2 | feet | of | ||
| soil | should | be | neglected, | due | to | surface | effects | and | potential | for | disturbance | due | to | frost | action | and | ||
| other | factors. | Frictional | resistance | should | be | assumed | to | be | mobilized | first | and | to | its | full | capacity | |||
| before | any | passive | pressure | is | developed. |
Construction Considerations General
| The | purpose | of | this | section | is | to | discuss | issues | related | to | geotechnical | aspects | of | construction, | as |
| required | for | development | of | the | project | specifications. | Included | are | anticipated | methods | of | ||||
| construction | and | identification | of | potential | construction | related | problems. |
Excavation
| We | anticipate | that | the | majority | of | the | excavations | can | be | made | using | conventional | earthmoving |
| equipment. | Although | bedrock | was | not | encountered | at | planned | excavation | depths | where | the | test | |
| boring | was | drilled, | excavations | at | the | revised | structure | locations | may | require | rock | removal | |
| techniques. | Rock | removal | by | means | of | blasting | should | not | be | allowed. |
| Due | to | the | excavation | depths, | excavation | support | systems | may | be | necessary | to | protect | existing |
| facilities | and | limit | excavation | quantities. | Excavation | support | systems | should | be | selected, | designed | and | |
| installed | by | the | Contractor. | Where | open | excavations | are | constructed, | the | side | slopes | should | be |
| designed | and | sloped | in | accordance | with | OSHA | regulations. |
| Undermining | of | existing | facilities | (structures | and | pipelines) | must | not | occur. | Excavations | within | the | ||||
| zone | of | influence | of | existing | structures | or | utilities | should | not | be | permitted | unless | the | design | of | the |
| excavation | support | includes | an | analysis | of | the | stability | of | the | structure | foundation | or | utility | and | as | |
| necessary, | incorporates | required | bracing/underpinning. | The | zone | of | influence | is | defined | as | a | line | ||||
| extending | 2.0 | feet | beyond | the | bottom | exterior | edge | of | the | foundation | or | springline | of | the | utility | then |
| down | and | away | at | a | one | horizontal | to | one | vertical | (1H:1V) | slope. |
Dewatering
| Groundwater | is | anticipated | to | be | encountered | during | the | excavations. | Contractor | will | be | responsible | ||||
| to | design | and | implement | a | dewatering | system | that | maintains | a | dry, | undisturbed, | and | stable | subgrade. | ||
| To | avoid | disturbance | to | the | subgrade, | the | water | elevation | should | be | maintained | at | least | 2 | feet | below |
01 01 00a - 7
| Keith | A. | Williams, | AIA, | PMP |
| October | 22, | 2013 | ||
| Page | 8 |
| the | subgrade | level | during | the | entire | period | of | excavation. | Where | required, | the | dewatering | system | is | ||
| expected | to | consist | of | pumping | from | open | sumps | within | the | excavation. | The | site | should | be | graded | to |
| direct | surface | runoff | away | from | the | excavations. |
| If | wet | weather | is | encountered | during | construction, | the | Contractor | should | take | care | to | schedule | ||||
| excavations | to | limit | the | duration | of | open | cuts, | slope | the | bottoms | of | the | excavations | to | facilitate | ||
| drainage | and | provide | berms | to | limit | runoff | into | the | excavations. | In | addition, | excavated | material | to | be | ||
| reused | as | fill | should | be | stockpiled | in | such | a | manner | that | promotes | runoff | and | limits | saturation | of | the |
materials.
| If | required, | the | Contractor | must | design | the | dewatering | system | to | not | adversely | impact | adjacent | |
| structures | or | site | features. | All | dewatering, | handling | and | disposal | of | pumped | water | and | any | special |
| testing | should | be | conducted | in | accordance | with | local | regulations, | permits | and | specified | requirements. |
Preparation and Protection of Foundations Subgrade
| Care | should | be | taken | to | avoid | excess | traffic | on | the | excavated | subgrades | prior | to | placement | of |
| structural | fill | or | concrete. | Final | excavation | should | be | made | using | a | smooth | edged | bucket | where | |
| possible. | Any | unsuitable | material | present | at | the | subgrade | level | should | be | removed | and | replaced | with | |
| compacted | structural | fill. | The | exposed | subgrade | should | be | protected | against | precipitation | and | the | |||
| subgrade | should | not | be | allowed | to | freeze. |
| Granular | soil | subgrades | should | be | proof | rolled | with | at | least | four | coverages | of | an | approved | vibratory | |||
| compactor | prior | to | placement | of | structural | fill. | Proof | rolling | should | not | be | conducted | where | the | ||||
| subgrade | consists | of | fine | sand | or | silt | or | clay, | however, | a | smooth | edge | bucket | should | be | used | for | final |
| excavation | in | such | soil. | Any | unsuitable | material, | such | as | topsoil, | organic | soils, | existing | loose | |||||
| miscellaneous | fill, | deleterious | materials | such | as | construction | and | demolition | debris, | or | any | other | soft, | |||||
| loose | or | disturbed | soil, | present | at | the | subgrade | level | should | be | removed | and | replaced | with | compacted | |||
| structural | fill. | Subgrade | excavation | and | foundation | preparation | should | be | performed | in | the | dry. |
Protection of Adjacent Structures and Utilities
| Excavation | activities | for | the | proposed | construction | will | be | made | near | to | the | existing | structures, | |
| parking | lot | and | utilities. | Protection | of | existing | facilities | is | the | responsibility | of | the | Contractor. | The |
| Contractor | will | need | to | take | adequate | measures | to | protect | existing | structures, | the | parking | lot | and |
| utilities | from | movement | and/or | damage. |
Pre‐construction Survey
| Prior | to | start | of | work, | a | pre‐construction | survey | should | be | conducted | for | structure | located | within | 50 | |
| feet | of | the | work. | The | survey | should | consist | of | a | description | of | exterior | and | interior | (as | appropriate) |
| conditions. | Descriptions | should | locate | cracks, | damage | or | other | defects | existing | and | should | include | ||||
| information | to | make | it | possible | to | determine | the | effect, | if | any, | of | the | construction | operations | on | the |
| defect. | Where | significant | cracks | or | damage | exists, | or | for | defects | too | complicated | to | describe | in | words, | |
| photographs | should | be | taken | and | made | part | of | the | record. | Contractor’s | record | of | the | pre‐construction | ||
| survey | should | consist | of | written | documentation, | video | and | photographs | of | the | conditions | identified. | ||||
| At | the | completion | of | the | survey, | submit | copies | of | the | documentation | to | the | Owner. |
01 01 00a - 8
| Keith | A. | Williams, | AIA, | PMP |
| October | 22, | 2013 | ||
| Page | 9 |
| The | Contractor | should | give | notice | in | writing | to | the | property | owner | and | any | representative | required | ||
| to | be | present | at | such | surveys | on | which | dates | the | surveys | are | planned | so | that | representatives | are |
| present | during | the | examination. | The | records | of | each | property | examined | should | be | signed | by | the | ||
| representatives | present | and, | if | practicable, | by | the | property | owner, | whether | or | not | they | are | present | at | |
| the | examinations. |
Settlement and Deformation Monitoring
| We | recommend | that | deformation | monitoring | points | (DMPs) | be | established | on | existing | structures | |||||||
| located | within | a | horizontal | distance | of | twice | the | maximum | depth | of | excavation | or | 50 | feet | from | the | ||
| excavation, | whichever | is | greater. | As | a | minimum, | DMPs | should | be | installed | on | the | exterior | wall | corners | |||
| of | buildings | or | structures | and | at | a | spacing | of | not | more | than | 25 | feet. | Where | excavation | support | is | used, |
| the | lateral | movement | of | the | system | should | also | be | monitored | using | DMPs | set | at | the | top | of | the | support |
| system | at | not | more | than | 25 | feet | on | center | along | both | sides | of | the | length | of | the | system. |
| Surface | monitoring | points | (SMPs) | should | be | installed | on | the | rim | of | existing | manhole | covers | of | utilities | ||||
| and | in | the | pavement | or | ground | surface | overlying | sensitive | utilities | located | within | a | horizontal | ||||||
| distance | of | twice | the | maximum | depth | of | excavation | or | 50 | feet | from | the | excavation, | whichever | is | ||||
| greater. | As | a | minimum | DMPs | should | be | installed | on | the | rims | of | manhole | covers | and | at | a | spacing | of | not |
| more | than | 50 | feet | on | center | along | utilities. |
| Monitoring | points | on | existing | structures, | pavement | and | utilities | should | be | installed | and | baseline | |||
| readings | taken | prior | to | the | start | of | installation | of | the | excavation | support | system. | Monitoring | points | on |
| the | excavation | support | should | be | installed | and | baseline | surveys | taken | prior | to | the | start | of | excavation. |
| The | monitoring | point | surveys | should | be | taken | daily | during | excavation | or | vibratory | construction | |||
| activities, | and | then | at | least | weekly | thereafter | until | all | backfilling | is | complete. |
Vibration Monitoring
| Ground | vibrations | due | to | construction | activities | such | as | the | installation | of | excavation | support | systems | |
| or | other | impact | or | vibratory | construction | activities | such | as | demolition | or | rock | removal | can | cause |
| damage | to | adjacent | structures, | utilities | and | other | facilities. | To | avoid | or | mitigate | this | potential | damage, |
| limits | on | ground | vibrations | in | the | form | of | ground | displacement, | velocity | or | acceleration | at | given |
| frequencies | are | typically | established. | The | Bureau | of | Mines | has | established | criteria | to | limit | ground | |
| vibrations | using | the | peak | particle | velocity | (PPV) | and | frequency | parameters. | These | limits | have | been | |
| established | using | the | cracking | of | plaster | walls | in | a | residential | house | as | a | model. |
| The | maximum | peak | particle | velocities | associated | with | impact | or | vibratory | methods | at | the | ground |
| surface | at | existing | adjacent | structures | and | utilities | should | be | as | follows: |
| Frequency | (Hz) | Max. | Peak | Particle | Velocity | (in. | per | sec.) |
| Over | 40 | 2.0 | ||||||
| 30 | to | 40 | 1.5 | |||||
| 20 | to | 30 | 1.0 |
Less than 20 0.5
01 01 00a - 9
| Keith | A. | Williams, | AIA, | PMP |
| October | 22, | 2013 | ||
| Page | 10 |
| In | no | case | should | the | maximum | peak | particle | velocities | exceed | 2.0 | inches | per | second | at | the | closest |
| facility | (structure | or | utility) | to | the | work. |
| A | minimum | of | two | seismographs | should | be | located | at | adjacent/nearby | structures | and | utilities | during | ||
| impact | or | vibratory | construction | activities | to | confirm | compliance | with | the | recommendations | herein | ||||
| and | record | actual | impact | vibrations. | The | Contractor | should | be | responsible | for | evaluating | and | |||
| selecting | equipment | the | can | meet | the | above | criteria | and | not | cause | damage | to | adjacent | structures, | |
| utilities | and | other | facilities. | If | the | induced | vibration | criteria | cannot | be | met | at | any | existing | structure, |
| other | means | of | construction | will | be | required. |
Backfill Materials Structural Fill
| Granular | fill | used | as | structural | fill | below | foundations | and | slab‐on‐grade | should | consist | of | a | mineral | |
| soil | free | of | organic | material, | loam, | debris, | frozen | soil | or | other | deleterious | material | which | may | be |
| compressible | or | which | cannot | be | properly | compacted. | Structural | fill | should | conform | to | the | following | ||
| gradation | requirements: |
| U.S. | Standard | Sieve | Size Percent | Passing | by | Weight |
| 3 | inches 100 | |||||
| No. | 4 | 20‐70 | ||||
| No. | 40 | 5‐35 | ||||
| No. | 200 0‐10 |
| In | addition, | material | meeting | the | gradation | requirements | of | PennDOT, | #2A | aggregate | is | acceptable | for |
| use | as | structural | fill. |
| Structural | fill | should | be | placed | in | layers | no | thicker | than | 8 | inches, | loose | as | placed, | and | compacted | with |
| suitable | compaction | equipment | to | at | least | 95 | percent | of | maximum | dry | density | as | determined | by | |||
| ASTM | D | 1557. | Lift | thickness | should | be | reduced | to | 4 | inches | in | confined | areas | accessible | only | to | hand |
| guided | compaction | equipment. |
Common Fill
| Common | fill | should | consist | of | soil, | free | of | roots, | vegetative | matter, | organic | material, | topsoil, | waste, | |||||
| construction | material, | highly | micaceous | silt, | frozen | soil | or | other | objectionable | material | that | cannot | be | ||||||
| properly | compacted. | It | should | contain | stones | no | larger | than | 6 | inches, | have | no | more | than | 75 | percent | of | ||
| material | passing | the | No. | 40 | sieve | and | a | no | more | than | 30 | percent | of | material | passing | the | No. | 200 | sieve. |
| It | should | have | a | maximum | liquid | limit | of | 35 | percent | and | a | plasticity | index | ranging | from | 5 | to | 15 |
percent.
| Common | fill | should | be | placed | in | layers | not | to | exceed | 12 | inches, | as | placed, | and | compacted | with |
| suitable | vibratory | compaction | equipment | to | at | least | 92 | percent | of | maximum | dry | density | as | |||
| determined | by | ASTM | D | 1557 | within | at | or | near | its | optimum | moisture | content(minus | 2 | to | plus | 3 |
| percent). | Lift | thickness | should | be | reduced | to | 6 | inches | in | confined | areas | accessible | only | to | hand | guided |
| compaction | equipment. |

Select Common Fill
| Select | Common | Fill | should | consist | of | soil, | free | of | roots, | vegetative | matter, | organic | material, | topsoil, | |||||
| waste, | construction | material, | highly | micaceous | silt, | frozen | soil | or | other | objectionable | material | that | |||||||
| cannot | be | properly | compacted. | It | should | contain | stones | no | larger | than | 2‐inches | in | diameter | and | have | ||||
| no | more | than | 75 | percent | of | material | passing | the | No. | 40 | sieve | and | a | no | more | than | 30 | percent | of |
| material | passing | the | No. | 200 | sieve. | It | should | have | a | maximum | liquid | limit | of | 35 | percent | and | a | ||
| plasticity | index | ranging | from | 5 | to | 15 | percent. |
| Select | fill | should | be | placed | in | layers | no | thicker | than | 8 | inches, | as | placed, | and | compacted | with | suitable |
| compaction | equipment | to | at | least | 95 | percent | of | maximum | dry | density | as | determined | by | ASTM | D | 1557 | |
| at | or | near | its | optimum | moisture | content | (minus | 2 | to | plus | 3 | percent). | Lift | thickness | should | be | reduced |
| to | 4 | inches | in | confined | areas | accessible | only | to | hand | guided | compaction | equipment. |
Re‐use of Excavated Fill
| We | anticipate | limits | portions | of | the | existing | fill | and | residual | soil | excavated | for | foundation | ||||
| construction | may | be | suitable | for | re‐use | as | common | fill. | All | materials | to | be | used | for | fill | or | backfilling |
| should | be | tested | for | conformance | with | the | requirements | herein | and | submitted | for | approval | prior | to | |||
| re‐use. | Excavated | fill | should | be | disposed | of | in | accordance | with | directions | of | the | Owner. |
Construction Monitoring
| It | is | recommended | that | a | qualified | Geotechnical | Engineer | or | an | experienced | Resident | Engineer | be | for | |
| the | project | be | present | during | construction | to | confirm | that | the | Contractor | complies | with | the | intent | of |
| these | recommendations. | Specifically, | the | Geotechnical | Engineer | or | Resident | Engineer | would | ||||||
| undertake | the | following | responsibilities: |
Monitor excavation activities;
Monitor dewatering activities;
Monitor instrumentation to ensure compliance;
Observe and document the preparation of foundation subgrades for proposed structures;
| Observe | and | document | the | removal | and | replacement | of | the | unsuitable | soils | present | at | subgrade |
| levels; | and |
