Soil Exploration
“ The process of exploring to characterize or define small scale properties of substrata at construction sites is unique to geotechnical engineering.
In other engineering disciplines, material properties are specified during design, or before construction or manufacture, and then controlled to meet the specification. Unfortunately, subsurface properties cannot be specified; they must be deduced through exploration.” Charles H. Dowding (1979).

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

Data Centers - Striving Within A Narrow Range - Research Report - MCG - May 2...pchutichetpong
M Capital Group (“MCG”) expects to see demand and the changing evolution of supply, facilitated through institutional investment rotation out of offices and into work from home (“WFH”), while the ever-expanding need for data storage as global internet usage expands, with experts predicting 5.3 billion users by 2023. These market factors will be underpinned by technological changes, such as progressing cloud services and edge sites, allowing the industry to see strong expected annual growth of 13% over the next 4 years.
Whilst competitive headwinds remain, represented through the recent second bankruptcy filing of Sungard, which blames “COVID-19 and other macroeconomic trends including delayed customer spending decisions, insourcing and reductions in IT spending, energy inflation and reduction in demand for certain services”, the industry has seen key adjustments, where MCG believes that engineering cost management and technological innovation will be paramount to success.
MCG reports that the more favorable market conditions expected over the next few years, helped by the winding down of pandemic restrictions and a hybrid working environment will be driving market momentum forward. The continuous injection of capital by alternative investment firms, as well as the growing infrastructural investment from cloud service providers and social media companies, whose revenues are expected to grow over 3.6x larger by value in 2026, will likely help propel center provision and innovation. These factors paint a promising picture for the industry players that offset rising input costs and adapt to new technologies.
According to M Capital Group: “Specifically, the long-term cost-saving opportunities available from the rise of remote managing will likely aid value growth for the industry. Through margin optimization and further availability of capital for reinvestment, strong players will maintain their competitive foothold, while weaker players exit the market to balance supply and demand.”

3. SUB SOIL EXPLORATION
3
• The process of collection soil data for the assessment soil
properties at a site through series of laboratory and field
investigation is collectively called Sub-soil Exploration
• Enables the engineers to draw soil profile indicating the
sequence of soil strata and the properties of soil involved.
4. COMMON STAGES IN SITE INVESTIGATION
4
• Desk Study
• Site Reconnaissance
• Field Investigations
• a) Preliminary Ground Investigation
• b) Detailed Ground Investigation
• Laboratory Testing
• Report Writing
• Follow up Investigations during design &construction
• Appraisal of performance
5. PURPOSE OF SOIL INVESTIGATION
5
Site investigation provides first hand information for
• Selection of foundation type.
• Design of foundations.
• Contractors to quote realistic and competitive tenders.
• Planning construction techniques.
• Selection of appropriate construction equipment (especially
for excavation and foundations).
• Feasibility studies of the site.
• Estimating development cost for the site.
• Study of environmental impacts of the proposed
construction.
7. The methods to determine the sequence, thickness and lateral
extent of the soil strata and where appropriate the level of
bedrock.
The common methods include
Test pits
Shafts and audits
Boring or drilling

METHODS OF INVESTIGATION
8. TEST PITS
8
The excavation of test pits is a simple and reliable method.
• The depth is limited to 4-5m only.
• The in-situ conditions are examined visually
• It is easy to obtain disturbed and undisturbed samples
• Block samples can be cut by hand tools and tube samples can
be taken from the bottom of the pit.
9. To identify the groundwater conditions.

oAuger boring
Percussion boring
BORING OR DRILLING
• Boring refers to advancing a hole in theground.
• Boring is required for the following
• To obtain representative soil and rock samples for laboratory
tests.
• Performance of in-situ tests to assess appropriate soil
characteristics. Some of the common types of boring are as
follows
• Auger boring
• Wash boring
• Rotary drilling
• Core drilling
• Percussion drilling
10. AUGER BORING
• HandAuger
• MechanicalAuger
• It is the simplest method of boring used for small
projects in soft cohesive soils.
• For hard soil and soil containing gravels boring with
hand auger becomes difficult.
• Hand-auger holes can be made up to about 20m
depth, although depth greater than about 8-10m is
usually not practical.
10
11. HANDAUGER
11
• The length of the auger blade varies from 0.3-0.5m.
• The auger is rotated until it is full of soil, then it is with drawn
to remove the soil and the soil type present at various depths
isnoted.
• Repeated with drawl of auger for soil removal makes boring
difficult below 8-10m depth.
• The soil samples collected in this manner are disturbed
samples and can be used for classificationtest.
• Auger boring may not be possible in very soft clay or
coarse and because the hole tends to collapse when auger is
removed
