SCOPE OF EXPLORA~IQN

The·purpose of this soil exploration was to Sllpplement our soil exploration

report, "Bougai:nville Industrial Park Off-site Sewers, 11 April il, 1975.

The sewer line between Manhole Nos. 5 and 8 l_la.s been realigned and the

installation of the sewer.line by an alternate method of tuil,nel:t:ng between

Manhole Nos. 5 and 12 is being considered.

This supplementary report covers only the portion of the project between

Manhole Nos. 5 and 12.

This report has been prepared for the exclusive use of. Community Pla.nning,

Inc. and their design consultants as a guide in the design of this specific

project. The report has not-been prepared for use by other patties and may

not contain sufficient information for other uses.

This -report includes field explorations, laboratory tests, general tunnel

design guidelines and limitations.

FIELD EXPLOR,ATl:ON

Two additional exploratory borings were lliade at the site. The approximate

locations of the borings are shown on the Revised Boring Location Sketch.

The borings were made with 4-in. diameter augers using finger-type bits

and rotary drilling using carbide bits~ Soil samples were recovered with

2 alld 3-in. thin-wall tubes and a standard split spoon sampler driven with

a 140-lb hammer falling 30 inches. Mudrock samples were recovered with an

"NX" double tube core barrel with a carbide coring bit.

Also attached are the logs of some of the borings from our previous report,

"Bougain:ville· Industrial Pg.rk Off-site Sewers," dated April 11, 1975.

LABQRATQRX TESTS

Laboratory tests included: natural water content.and density, Atterberg

limit, grain-size analysis and unconfined compression.

A sUmma.ry of the laboratory test results ·is given in Table lC •.

SOIL CLASSIFICATION SYSTEM

Soil samples were visiUally obser\Ted and subjected to appropriate tests

in the laboratory. Based on visual observations and laboratory tests,

the soil descriptions given on the boring logs are generally made in

accordance with the "Unified So:J.l Classification System."

GEOLOGIC AND SOIL CLASSIFICATIONS ~y OTHERS

From a review of·geologic literature and the U. S. Soil Conservation

Service maps of the area, the soils ar~ generally descr~bed by others

as follows:

Stearns, H. T. and U. S. Geological Survey, "Geologic and

Topographic Map, Island of Oahu," USGS 1938:

Qht - Honolulu Volcanic Series

Consolidated volcanic tuff (locally called

mudrock). Makalapa Crater was formerly a

lake or pond according to the U.S.G.S. arid

the 1968 Quandrangle maps of the area.

U. S. Soil Conservation Service, "Soil Survey of Islands

of Kauai, Oahu, Maui, Molokai and Lanai, State of Hawaii,"

August 1972:

MdB - Makalapa .clay~ 2 to 6% slopes

Unified Soil Classification - Cll

KTK.E - Kokokahi very stony clay, 0 to 35% slopes ·

Unified Soil Classification - CH

GENERAL SITE CONDITIONS

The proposed sewer alignment is about3,600 ft in. length and extends from

Bougainville Road to S11lt .Lake Boulevard. The route crosses the back

(westerly) portions-of Hale Keiki School, Radford'High School-and Makalapa

- 3 -

e

e

e

Elementary School grounds. The proposed tunnel portion may extend for

approximately 1,500 ft al.ong thewesterly portions of Makalapa Elementary

School an9. Radford High SchooL

A 30-ft· w:i.<ie energy corridor and the H-1 Freeway are located on the west

side.of theproposed route. Ashallow unlined gitc:.h.generally follows

alongside the freewa:y and energy corridor.

A Navy utility tunnel crosses under the· proposed sewer invert between

Manhole Nos .• 6 arid 7. the ~istiil.g tunnel is about 10 ft high and crosses

about 8 ft below the proposed sewer invert. The tunnel is believed to be

lined.

A.track field, bleachers, floodlights, (;!lassroom building, parking lot,.

basketball court, Navy water lin~s and some concrete structures occur

along the proposed route in back of (west) Radford High School ap.d

Makalapa Elementpry Scl:loolgrounds.

INTERPREl'ATIO~ OF SOIL .CON]HTI:O~S

Froijl the field explorations and laboratory test results, the soils

·encountered in the borings may be generally approximated as follows:

~qrthe_rn Portion (~tihole Nos. 5 thru 10)

About 3 to 15 ft of fill over dense mudrock (:volcanic tuff)

. to below the proposed tunnel invert to ZS .to 51 ft, the

depth drilled.

Stiff clay was noted in 2 of the borings at about 35 to

37-ft depths, approximately 4 to 6 ft below the proposed

invert.

- 4 ....

e

e

. e

Southern ~Qrtion (Manhole Nos• 11 and 12)

About 8 to 13ft of fill over soft to mediUiil clay to 33 to

37 ft. Below this: st:f,.ff clay to 36 to 41 ft, the depths

drilled.

Water was not .noted in the borings in the northern portion. Water was

noted at about 10-ft depths in the southern pot:tion (Manhole Nos. 11

and 12).

For more detailed descriptions of soils encountered in the borings., te.fer

.to the boring logs.

Variations to the above soil and water conditions are to be expected between

borings and in localized'areas.

DISCUSSION AND RECOMMENDATIONS

A 12-in. diameter gravity flow sewer line about 3,600 ft in le:p.gth is

propose9. A soil exploration report, ''Bougainville Industrial Park

Off-site Sewers, dated April 11, 1975, was prepared by our office for

sewer pipe ]le(:ld:lng design purposes. Due to the depths of the excavations

(up to 38 ft) between Manhole Nos. 5 and 12, installation of .a portion

of the sewer by tunneling is being contemplated.

The profile of .the ground starts at about elevation 33 ft at Manhole

No. 5 and ri!;!es to about 58 ft at Manhole No. 6. Between Manhole Nos~ 6

and9,,the ground varies from about 58ft to 64ft, then slopes down to

about elevation 45ft a~. Manhole No. 12 •

- 5 -

e

e

-

The invert of the proposed sewer line generally varies from about elevation

26 ft at Manhole No. 5 to about elevatio~ 30.5 ft at Manhole No. 12.

The tunnel diameter should be about 30 to 42 in •. to allow personnel to

enter the tunnel to lay the pipe.

For the proposed tunnel, between Sewer Manhole Nos. 5 and 12, the following

may be considered:

Tunnel Lining

Manhole Nps. 5 thr'Q No. 10

The borings indicate that the proposed. tunnel .will

probably be mostly in mudrock (volcanic tuff).

The tunnel lining will. depend I)lostly Qn the competency

of the 'll$terial encountered and the locations of any

nearby structures.

Where dense mudrock is encountered, minimal ot no

supports may be required.

Linings should be considered for the adit and exit,

about the first and last 15 ft of the tunnel, and

where the new tunnel croeses over the existing Navy

utility tunnel (see Figure 1). The lining may be

cot ruga ted metal pipe with the space between the

lini11g and excavation filled with grout.

- 6 -

e

e

-

Wh~re loose or ravelling pockets are encountered,

the loose pockets may be grouted or mortared or

supported with a metal liner and the space between

the lining and ground fille4 with grout. The

selection of the support should bemade by the

contractor to suit his judgment and requirements.

~nbol~ Nos. 10 thru lZ

The borings indicate that theproposed sewer invert

may be·mostly in soft to medium clays and partly in

mudrock •.

Water was encountered in Boring Nos. 5 and 6.

Due to the soft material and possibility of

encountering water if tunneling is considered, the

tunneling should be done withc~re. A lining is

recommended.

The borings indicate that the boundary between the

mudrock. and soft clays may be between Manhole

Nos. 10 and 11.

Other general guidelines for tunneling and sewer pipe installation

may be as follows:

1. In soft or ravelling ground, the lining should

be placed a;s soon· as practicable.

- 7 -

e

e

e

2. Where water is encountered, the tunnel should

be drained before the installation of the sewer

line.

3. For the sewer bedding, low-grade concrete or

grout may be use.d.

Transition for Open Trench·Method

If the sewer between Manhole Nos. 10 and ll is placed by open

trench method, a gradual transition for the pipe bedd;i.ng in

the mudrock formation and the clay should be. considered. This

may lessen tl).e possibility of crack:i,J),g the sewer pipe which

will be partly supported on mudrock and partly on clay.

The transition zone may be constructed by overexcavating the

mudrock from 0 ft at Manhole No. :1,0 to·3 ft at the boundary

between mudrock and clay and backfilling the excavation with

uncompacted select granular material.

Water

Water was not noted in the drill holes in the northern .

areas but was noted in the drill holes in the southern areas.

Therefore, the possibility of encountering water should be

considered~

Field Allowances

The contract docinnents should allow for field changes in tunnel

.lining, bedding, etc.

- 8 -

e

UnJoreseeu. CJ>nditions

Because of the variability of soil deposits, site

improvements, designs and construction techniques, existing

or changed conditions may be encountered that .cannot be

foreseen with even the mast exhaustive studies of site and

project conditions. These-unforeseen conditions should be

~ecognized when encountered and then evaluated so that the

designs or the construction methods may be modified accordingly,

if necessary.

Unforeseen or changedor :Ut_ldetected conditions such as soft

spots, new ot existing utility trenches, :underground structures,

pipes, voids or cavities, cesspools, boulders, e;Kpansive soil

pockets, rubbish or boulder disposal pits, seepage water or

water level changes with weather, etc., may accur.in localized

a:tea,s and will have to be adjusted and corrected in the field

as they are det:ected.

Review of Plans, Specifications and Construction

Our basic scope o:f.wotk <Joes not .include review of plans,

specifications and construction observations.

It is'te<;:ammended that the soil and foundation engineer reviE;!w

the fimrl plans and specifications for general conformance with

the earthwork and foundation.guidelines of the soil repott.;

,... 9 -

e

-

e

It is also recommended that the soil an4 foundation engineer

be retain.ed to provide engineering services during t'he foun.da­

tion phases of the work. This will allow the soil engineer

to observe general compliance with the design concepts,

specifications or recommendations and .to allow design changes

in the event that subsurface conditions differ from that

anticipated prior to start of construction.

In th~ event that changes in the nature, qesign or locatio11

of the project are planned, the recommendations contained

in this report shall not.be con~idered valid unless th~

changes are reviewed and the contents of this report modified

or verified in writing.

We must emphasize that our recommendations are based on the boring logs included in this report and th~ information conta:il)ed thereon and not on the field logs.

The boring logs in this report represent our interpretation of the contents of the field logs, and the results of the laboratory observations and tests of the field samples.

The stratification lines shown on each of the boring logs represent the approximate boundary between soil types and the transitions may or may not be gradual. · ·

Symbols

Soil symbols used generally are in accordance with the Unified Soil Classification System.

Where a parenthesis 11 (MH) 11 is used, the soil sample was classified by visual observation of the sample recovered.

Where no parenthesis "MH" is used, the soil sample was classified from either the Atterberg limit or grain-size analys:f,.s test pesults.

Rock Cores

The Rock Quality.Designation (RQD) is based on a modified core recovery ratio.

This ratio is determined by considering only pieces of core that are 4-in. and longer a~d fairly hard. The percentage ratio between the total length of such cores recovered and the. length of core drilled on a given run is designated as the RQD.

LIM11'ATIONS

In general, soil formations are commonly erratic and rarely uniform.or

regular. The·boring logs indicate the approximate subsurface soil

conditions encountered only a.t the drill holes where the borings were

made at the times designated on th~ logs and may not represent conditions

between borings, at other locations, or at other dates. Soil conditions

andwater levels may change with the weather, passage of time and

construction methods or improvements at the site.

During construction, should subsurface conditions ro:uch different from

those in the borings be observed, encountered, or otherwise indicated, we

should be advised immediately to review ot reconsider our recommendations

in light of the new developments.

If there is a substantial lapse of time between the submission of this

report and.the start of work at the site, or .if conditions have. changed due

to naturai causes,.plan changes, or construction operations at or adjacent

to the site, it is recommended that this report be reviewed to determine

the applicability of the :tecommend.ations considering the time lapse,

chang.ed conditions, and changes in the state of the art of soil engineering.

Out professional services were performed, findings obtained and

recommendations prepared in accordance with generally accepted engineering

practices. This warranty is in :)..ieu of all other warranties expressed ot

implied.

LIMITATIONS ( cont 1 d.)

Contract documents and specificatio11s often prescribe supervision by the

·soil engineer. It should be. understood by all parties that the soil

engineer's actual scope of work is very limited. We as the soil engineer

do not assume the day to day physi~al direction of the works, nor minute

examination of the elements, nor do we assume the.responsibility for the

safety of the contractor's workmen. Supervision, inspection, control,

etc., by the soil engineer genera],ly I;llean taking of soil tests and making

visual observations, sometimes on only an intermittent basis relating to

earthwork or foundations for the project. The soii engineer does not

guarantee the contractors' performance, but rather looks for general

conformance to the intent of the plans and soil report. Any discrepancy

noted by the soil engineer regarding earthwork or foundations will be

referred to the project engineer or architect or contractor for action.

8-75

Although the soil report may comment or discuss construction techniques

or procedures for the design engineer's guidance, the report should not

be interpreted to prescribe or dictate construction procedures or to

relieve the contractor in anyway of his responsibility for the construction.
