2.0 PROJECT AND SITE DESCRIPTION
Based on the provided information received from the client, it is understood that the proposed project will consist of several buildings with approximate foot print areas, number of floors
and finish floor levels (F.F.L) as indicated in the following table:
Table 1: Building Names, Number of Floors, Floor Areas and F.F.L.s
The site located on the eastern shore of the Dead Sea / Jordan. The site is boarded by anexisting paved road from the north-east, the Dead Sea from the south-west, the existing"Holiday Inn" hotel from the north-west side and by unutilized plots from south-east side. Thesite slopes down toward the Dead Sea direction with an average slope of about 10%. It iscrossed by deeply incised, steep sided and relatively wide wadi.
A general site plan showing the location of the project and both drilled boreholes andexcavated test pits is presented in Figure No. 1 . Figure No.2 shows some of the project site
photos.
3.0 GENERAL GEOLOGY
Based on the geological map of the area (Al Karama 3153-IV), the project area belongs toLisan Formation of Jordan Valley Group of Quaternary Period and Pleistocene Epoch. Thisformation consists predominantly of millimeter-to-centimeter-laminated, very weak, friable,low density, white, calcareous mudstone with alternating white marl, greenish brown clay andevaporates. In the water saturated state they behave as soft clays. Micro-faults and controlledlaminations are typical. This formation was formed in brackish water of the Lisan Lake which
occupied the Dead Sea basin during the Late Pleistocene. Sandy gravel lenses are common within the Lisan Marl. The thickness of these lenses mayvary form few centimeters to more than one meter.

4.0 SEISMICITY AND EARTHQUAKES
According to the Jordanian seismic code (published by the ministry of public works andhousing in October 2005), the site lies within Zone (3) , with a seismic zone factor of Z=0.30 .
The formations are classified as (S D) type. The seismic factors related to the accelerationCa=0.36 ; whereas, the seismic factor related to the velocity CV=0.54 . These factors should beused in the design of the proposed project.
5.0 FIELD EXPLORATION AND LABORATORY TESTING
5.1 Field Exploration:
The field exploration consisted of borehole drilling; test pits excavation and field densitytesting.
5.1.1 Drilling and Sampling:
Twenty five (25) boreholes were drilled between February 5 th and March 5 th, 2012.The boreholes were drilled to approximate depths ranging from 10 to 23m below theexisting ground level. The locations of these borings are indicated in Figure No. 1 . The borehole information is presented in Tables No. 2 .
The locations of the boreholes were selected and marked in the field by the staff ofACES. Table No. 2 shows the borings names, locations (coordinates), elevations,F.F.L's, and exploration depths. The elevations at the top of boreholes were estimatedaccording to the topographic map provided by the client and should be consideredapproximate. Samples were visually examined and described by ACES staffaccording to ASTM D2488-09a.
The drilling was executed with " Edeco (36/1) rotary rig, mounted on Mercedestruck 1417, capacity 400m " and " Toho 2P rotary rig, mounted on Mercedes truckLK608, capacity 800m " using the rotary air flush percussion drilling technique .
Standard Penetration Tests (SPT) was performed at various depths in the drilled boreholes to obtain the approximate dynamic resistance of the ground materials. Thetests were performed in accordance with ASTM D 1586-08a (Standard Test Methodfor Standard Penetration Test (SPT) and Split-Barrel Sampling of Soils).
The SPT blow counts at different depths are presented on logs of borings (AppendixA). The definition of Standard Penetration Test (SPT) and useful SPT correlations are

Geot. Eng. M.M / S12000003 11 of 33
presented in the legend of borings logs (also in Appendix A). Further discussion onthe results obtained from SPT is presented in Section 6.4.
Disturbed but representative soil samples were retrieved from inside the split spoon
samplers used in the SPT test. The recovered samples were placed in air-tight plastic bags to maintain the moisture content.
Percussion (down-the-whole hammering) drilling techniques were used at otherintervals where no SPT sampling was performed.

6.0 SURFACE AND SUBSURFACE CONDITIONS
6.1 Ground Materials:
From Boreholes
The drilled boreholes generally encountered the following materials:
Fill material composed of loose fine coarse grain sand and gravel and cobblesof sandstone, limestone, chert and basalt with few asphalt and concretefragments. This material was encountered in all boreholes except : BH1, BH2,BH3 and BH4. It extends from the surface level to an approximate depthranging from 0.5m to 6.0m below the existing ground surface.
Alluvial deposits composed of alternated to intercalated lenses of brownish
yellow gravely sand to sandy gravel with silty to marly clay. This material wasencountered at the surface of BH1, BH2, BH3 and BH4 or below the fillmaterial of BH5 and BH6 and extended to depth ranging from 1.5m to 13.0m
below the existing ground surface.
Alluvial (wadi) material composed of varicolored gravel and cobbles ofsandstone, limestone, chert and basalt with coarse grained sand. This materialwas encountered below the fill material in boreholes BH9, BH10, BH12, BH15,BH16, BH18, BH19, BH20, BH22, BH24, BH25, BH26 and BH28 andextended to depth ranging from 5.0m to 10.0m or to the end of this boreholes.
Grayish off white fine to medium grained sand alternated with thin silty sandand some coarse sandy gravel. This material was encountered below the fill oralluvial material in boreholes BH9, BH10, BH11, BH12, BH13, BH14, BH15,BH18, BH22, BH25, BH26 and BH27 and extended to the end of these
boreholes.
Grayish yellow to greenish gray firm to stiff marly clay (lisan marl) intercalated with white aragonite gravely sand. This material was encountered
below the alluvial or fill material in boreholes BH1, BH2,BH3, BH4, BH5,BH6, BH7, BH18, BH20, BH24, BH27 and BH28 and extended to the end ofthese boreholes.
Generalized subsurface profiles are presented in Appendix B . More information about theencountered materials can be obtained from the logs of borings ( Appendix A ).

Geot. Eng. M.M / S12000003 15 of 33
Note that the grain size analyses performed on the fill and alluvial materials in boreholesare not representative of the formation as it was performed on the disturbed samplesobtained during drilling where all the gravels, cobbles and boulders were broken into
pieces. On the other hand, the grain size analyses performed on the materials from tests
pits are more representative.
From Test Pits
The encountered material in test pits TP1, TP3 and TP5 were Lisan marl materialscomposed of soft to very stiff, thinly laminated bands of greenish gray clay and whitearagonite marl, with some fine grained sand lenses. The material encountered in test pitTP2 and TP4 was grayish yellow highly weathered disintegrated clayey silt and TP6 wasAlluvial deposits composed of gravel and cobbles of sandstone, limestone and chert withcoarse grained sand and some silty sand.
More information about the encountered materials can be obtained from the logs of test pits ( Appendix A ).
6.2 In-Situ Test Results:
The in-situ testing mainly composed of two types: SPT within the drilled borehole andfield density on the excavated test pits.
6.2.1 Standard Penetration Test (SPT):
Standard Penetration Test (SPT) was performed at various depths in the fill, alluvial
deposits, sand and lisan marl materials to obtain approximate dynamic resistance ofthe ground materials. Several empirical correlations have been established to relate theSPT blow count (N) with relative density and friction angle for granular materials.
Table No. 4 presents the SPT depth in each borehole, the materials at that depth, SPT blow counts and the corresponding SPT N values. The definition of SPT and usefulSPT correlations for granular soils are presented in the legend to boring logs(Appendix A). The SPT (N) value ranged: from 16 to refusal in fill materials; from 25to refusal in the alluvial and sand materials and from 18 to refusal in lisan marlmaterials. The measured blow counts (N) classify the alluvial, sandy and lisan marlmaterials as " medium dense to very dense". However, the relatively high N value may
have resulted from the presence of gravel and cobbles within the soil matrix.

6.3 Groundwater and Cavities:
No free ground water or cavities were encountered in any of the boreholes to the drilleddepths during or after the completion of drilling activities. However, the surface hydrology
is outside the scope of this study.
6.4 Material Chemical Properties
6.4.1 Sulphate Content
Sulphate content (expressed as [ SO 3]) for the tested soil samples are shown inTable No. 8.
Sulphate attack to concrete is well documented phenomena and is caused by the presence of high sulphate content either by the ingress of the sulphate of the
surrounding environment, such as foundations soils, or by the presence of sulphatein the concrete ingredients, such as sand or aggregate, or both.
The attack results in a considerable internal expansion which may lead to crackingand disintegration of the concrete.
Based on the sulphate content present in the foundations soils; this site can beclassified within class 3 as categorized in BS 5328:Part 1 (see Appendix D). Therequirements of BS 5328:Part 1 for class (3) are to use ordinary portland cement,sulphate resisting portland cement, or blast furnace portland cement or supersulphated cement with minimum cement content of 320 and 340 kg/m3 and
maximum free water to cement ratio of 0.5 and 0.5, respectively.
Taking into consideration the characteristics of the proposed project, its functionand the presence of ground water, it is recommended that the overall site be treatedas class (3) which presents the severe conditions.

6.4.2 Chloride Content in Ground Materials
The chloride content for the tested soil samples are also presented in Table No. 8.
There is no widely accepted view on the concentration which chlorides becomesignificant in soil or ground water, but limited experience in the region suggests itmay be as low as 0.05%, particularly in situations where alternate wetting anddrying or capillary rise affect the concrete (CIRIA Guide, 1983).
As shown in Table No. 8 , the chloride content in the tested soil samples is morethan 0.05% and is considered significant.

6.4.3 pH Value
Soil pH is one of the most common soil chemical measurements. It provides theinvestigator with information about the solubility of various soil compounds, theadsorption behavior of ions to soil surface and the microbial activity of soilsystem. The measured pH values listed in Table No. 9 indicate that the testedsamples are alkaline, with values ranging from 8.18-8.82. These values areconsidered not detrimental to steel.
6.4.4 Carbonate Content
Carbonate content in the tested samples is considered slightly high (i.e., more than40%), which is normal due to the nature of alluvial material.

6.4.5 General Recommendations
Where resistance is needed against both sulphates and chlorides, it is highlyrecommended to protect the concrete from the soil and groundwater with
waterproofing membrane or tanking, and a compromise has to be made onthe type of cement used. Generally, cement containing at least 3.5% but not morethan 9% C3A is preferred. Each situation should be considered on its merits.
It is advisable that the designer shall consult CIRIA Guide to ConcreteConstruction in the Gulf Region, once the exposure conditions of the designedstructures are finally determined, in order to determine, more accurately, thecement type (Figure 6 - Appendix D ) and range of specifications limitsrequirements for minimum cement content, maximum water cement ratio andminimum cover for reinforcement (Table 13 Appendix D ).

7.0 CONCLUSIONS AND RECOMMENDATIONS
According to the field and laboratory investigation, subsurface conditions, engineeringanalysis and practical experience, we believe that the proposed project can be satisfactorily
supported by the ground at the site, provided that the following recommendations areconsidered:
7.1 Foundation Depth and Type
Main Building (Block C).
Foundation of the Main building are to be constructed at an approximate elevationof -407.0m and -403.0m. The investigation indicated that part of the main building site(adjacent to Holiday Inn Hotel site) is covered by dumped fill reaching 6m in thickness.
Most of these fill materials will be removed to reach the design level of foundation.However, if any dumped fill will remain below the design level, it should be eithercompletely removed or excavated to a minimum depth of 1.5m and replaced by selectedfill materials, as described herein later.
The investigation indicated that ground materials encountered at the expected foundationlevel of the main building are alluvial deposits, lisan marl, and/or engineered fillmaterial (due to difference in elevations and especially, above the proposed culvert),which are characterized by large variations in properties and strength parameters in bothvertical and horizontal extends. Therefore, foundations may be subjected to significantdifferential settlement and differential movement may cause damage to the foundations
and structures. Accordingly, raft foundations are essential to support the 6-7 story main building.
However, if the client chooses not to adopt this solution and assuming that occurrence ofsome minor cracks (especially within the partition walls, in the plaster, in the interface
between different structural elements, along water and electrical installations, etc.) isacceptable, the following alternative may be adopted.
a. Unify foundation ground by Excavating of minimum of 1.5m below foundationlevels
b. Backfill the over excavations with selected fill up to a height of 1.2m. Theselected fill shall be a soil or soil rock mixture, which is free from organicmatter or other deleterious substances. It shall not contain rocks or lumps over15 cm in greatest dimension, and not more than 15 percent larger than 7 cm.

26/143
Geot. Eng. M.M / S12000003 24 of 33
The fine materials (passing sieve 200) shall not exceed 35 percent (materialsclassified as A-1-a, A1-b and/or A-2-4 according to AASHTO Classificationare considered suitable for this purpose). Selected fill shall be spread in liftsnot exceeding 20 cm in uncompacted thickness, moisture conditioned to its
optimum moisture content, and compacted to a dry density not less than 95 %of the maximum dry density as obtained by modified proctor compaction test(ASTM D 1557).
c. The remaining top 30cm of the over excavation shall be backfilled either withcyclopean concrete (plain concrete with approximately 40% stones) or withengineered fill.
If engineered fill is used, it should be spread into two lifts and each lift shall becompacted to a dry density not less than 97 percent of the maximum density asobtained by modified proctor compaction test (ASTM D 1557-09). The
plasticity index for the base course material shall not be more than 6 percent. Itshall be composed of graded crushed stone satisfying all the requirements of
base course materials according to the Standard Specifications for theConstruction of Roads and Bridges, Ministry of Public Works, Jordan.
d. Foundations system with sufficient rigidity (i.e, strip foundation and/or isolatedfooting with tie beam constructed at foundation level) can be erected on thefoundation ground prepared as described above.
e. Foundations constructed as described herein shall be designed using a netallowable bearing pressure value of 1.5 kg/cm 2.
Building AFoundation of the building A are to be constructed at an approximate elevation of -410.5m. Ground materials encountered at the above elevation are alluvial deposits,and/or fill material. These deposits are characterized by large variations in propertiesand strength parameters in both vertical and horizontal extends. Therefore, foundationsmay be subjected to significant differential settlement and differential movement maycause damage to the foundations and structures. Accordingly, shallow foundationssystem with sufficient rigidity is recommended to support the two (2) story building. Inorder to enhance the rigidity of the foundation systems, foundations shall be tiedtogether with ground tie beams constructed at the foundation level.
Differential settlement may also be reduced by reduction of the transmitted pressure,which, in turn, can be achieved by separating the foundations from the foundationground by a 30 cm thick cyclopean concrete layer (i.e., plain concrete withapproximately 40% stones).

Geot. Eng. M.M / S12000003 25 of 33
Building B, C & D
Foundation of the building B, C & D are to be constructed at an approximate elevation
of -413.5m. Ground materials encountered at the above elevation are lisan marl.Although, these materials are relatively homogeneous, significant variations in strength
parameters in both vertical and horizontal extend may take place as a result of the possible local water submergence. Accordingly, shallow foundation systems withsufficient rigidity are recommended to support the 3 story building. In order to enhancethe rigidity of the foundation systems, foundations shall be tied together with ground tie
beams constructed at the foundation level.
Differential settlement may also be reduced by reduction of the transmitted pressure,which, in turn, can be achieved by separating the foundations from the foundationground by a 30 cm thick cyclopean concrete layer (i.e., plain concrete with
approximately 40% stones).
Based on the above mentioned analysis for the proposed structures, finish floor levels(F.F.L), bearing materials, depth of foundations and foundations types are provided inTable No.9:

7.2 Allowable Bearing Pressure

Since Meyerhof proposed his original correlation, researchers have observed that itsresults are rather conservative. Later, Meyerhof (1965) suggested that the net allowable
bearing pressure should be increased by about 50%. Bowles (1977) proposed that themodified form of the bearing pressure equation be expressed as

Where:
NC N: corrected standard penetration number,
NC N: N x 9.78 ( )2, //1 mkN N N : measured standard penetration test N value. N: effective overburden pressure.
As mentioned earlier, there is a large variation in the soil strength in both horizontal
and vertical extends as indicated from the SPT test results. Therefore, second lowestvalues below foundation influence are taken into consideration in bearing capacitycomputing, as presented below.
Many authors do not consider correction to N values of SPT for depth shallower than 5.0m. Other correction factor is considered based on used hammer energy. The correctionfactor of this type the used in the investigation hammer is 0.75. Accordingly, theadopted corrected number of blows for shallow foundations are as follows:

7.3 Foundation Settlement:
The consolidation settlement for the alluvial materials is expected to be insignificant
(negligible). The elastic (immediate) settlement of the materials can be calculated usingthe following equation based on the theory of elasticity [e.g, Timoshenko and Goodier(1951)]:
s = qa xB (1- 2) IEs
Where:s: settlement of the corner of a rectangular base (mm). qa: net allowable bearing pressureB: the width of the foundation, approximately equal to 1.0m for isolated (square strip and
raft) footings
I: combined depth, roughness and bedrock thickness influence factor, which is equal to: 0.88 for square footing 2.1 for strip & raft footing ( L/B=10 )
: the Poisson's ratio of the materials; is generally about 0.3 for soils.E: Youngs modulus of soilE= 7000 N0.5 Therefore, the estimated foundation settlement is:
Table No.12: Settlement values:
Since the fill materials is erratic and does not have uniform engineering properties,settlements could not be predicted using conventional settlement calculations. However, ifconstruction was performed according to the recommendations above, settlements areexpected to be within allowable limits.

7.4 Subgrade Reaction:
For the design of raft foundations on these layers, the conservative value of the modulus
of sub-grade reaction is calculated using the allowable bearing pressure ( 1.5 Kg/cm2
) asfollow:
For design of culvert and main building raft foundations, the following modulus ofsubgrade reaction may be calculated from the standard penetration number of blows (Nvalue):
K 0.3 = 1.8 Ncor (MN/m 3) (Scott 1981),K 0.3 (for base diameter of 0.3m)
Accordingly, the (K 0.3) value will be : (1.8*13=23.4 MN/m 3 ( 2.3kg/cm 3))

Where (B) is foundation width.
7.5 Excavation Methods:
It is expected that the excavation will be carried out through the fill, lisan marl and alluvialmaterials. Therefore, pneumatic equipment such as jackhammer will be needed in additionto the conventional excavation equipment such as loaders and dozers for excavation workat the site.
7.6 Excavation of Side Slopes:
To minimize the stability problems, the temporary excavation sides should be cut at a faceinclination not steeper than o ne horizontal to one vertical (1H: 1V) for the fill andalluvial materials.
If these side slopes can not be achieved for insufficient lateral distance or for any otherreason, temporary lateral support (shoring) system may be necessary and should beconsidered.

7.7 Drainage:
It is recommended to protect the foundation ground and excavation from surface water both during and after construction by providing proper drainage and protection system andmaintaining the sewer and water system of the buildings continuously. The rain water andsurface water (if any) which is collected from the rain water ducts and from groundsurface should be directed away from the buildings.
Proper drainage should also be provided at all retaining walls (if any) in the form of either perforated drain pipes or weep holes across the wall. A filter/drainage blanket or layerapproximately 50 cm wide should be backfilled against all retaining walls consisting ofopen graded filter materials (single size gravel may also be used). Gradation requirementsfor filter material are outlined in the following paragraph.
7.8 Backfill Materials, Selected Engineered Fill and Compaction Criteria:
The existing fill materials are considered suitable for backfilling purposes.
Backfill Materials:
The materials to be used for backfilling purposes under bottom slab and behindunderground walls shall be a soil or soil-rock mixture, which is free from organic matteror other deleterious substances. It shall not contain rocks or lumps over 15 cm in greatestdimension, and not more than 15 percent larger than 7 cm. The fine materials (passingsieve 200) shall not exceed 35 percent. The plasticity index for the backfill material shall
not be more than 10 percent. It shall be spread in lifts not exceeding 20cm in uncompactedthickness, moisture conditioned to its optimum moisture content, and compacted todensity not less than 95 percent of the maximum dry density as obtained by modified
proctor compaction test (ASTM D 1557-09).
Selected Engineered Fill:
The engineered fill materials shall be composed of well graded granular material. It shall be spread in lifts not exceeding 20cm in uncompacted thickness, moisture conditioned toits optimum moisture content and compacted to a dry density not less than 97 percent ofthe maximum density as obtained by modified proctor compaction test (ASTM D 1557-
