GEO‐TECHNICAL ENGINEERING SERVICES
BBFL Consultants Ltd. recognizes the need to have control over key processes in order to deliver a
finished quality product on time. It is with this in mind that we have identified the need to develop our
own Geo‐technical and Material Testing capabilities as dependence on sub‐contractors has shown a
history of delays, poor quality testing, high costs to the client and unclear and subjective data results.
All civil engineering projects, soil and investigation are necessary in determining the type and extent of
foundations required. On civil projects such as land developments, road designs and bridge designs, a
number of soil investigations and material testing are necessary for determining proper parameters for
the design of pavements, substructures, landslip reinstatement, pavement rehabilitation, etc.
In recognition of this need our affiliate company Earth Investigation Systems Limited, (EISL) was created.
EISL is a civil engineering laboratory facility headed by our principal geo‐technical engineer Dr Derek Gay.
Our Technical Services section is headed by a senior materials technician Mr. Samuel Ames, who is ably
supported by other qualified technical staff.
This facility currently offers the following testing services:
• Atterberg Limits
• Moisture Content
• Hydrometer Analysis
• Unconfined compression strength
• Sieve analysis
• Standard & Modified proctor test
• Triaxial testing
• California Bearing Ratio (CBR)
• Insitu field permeability/percolation
• Mix design
• Extraction and Gradation
• Maximum specific gravity
• Flakiness Index and Elongation Index
• Soundness Test
• LAA – Los Angeles Abrasion
• ACV ,EIV
• SO4 – Sulphate, PH, Chloride Tests
• Dynamic Cone Penetration (DCP)
• Asphalt coring and concrete coring
• Deflection Surveys
• Insitu Density
• Compressive strength test
• Slump test
• Concrete cubes and cylinder
All tests and services are carried out in accordance with the current ASTM standards. However, these can
be easily adapted to any other standard to meet the needs of specific project requirements.
EISL has its own drill crew who uses a small rig to do
shallow boreholes (less than 150 feet) for bridges,
landslide investigation and for structural foundation.
For deep drilling EISL retains the services of WALKERWELL limited who are equipped with five drilling rigs
all of which is capable of drilling over 1000 feet. Following is a description of their smallest rig.
The Failing “1500” Holemaster is a tough, compact, mobile
drilling unit. Its rugged construction and medium weight are
combined to give you an exploratory drill of extreme
versatility. Handles all types of exploration drilling to 1500
feet, yet it is light enough for efficient performance in
seismograph shot‐hole work.
The Failing “1500” Holemaster is manufactured in the heart of
the oil country. Engineered by men who know the problems and requirements of practical drilling.
Precision built on a production line basis, insuring availability of interchangeable repair parts at all times.
Parts are made from the finest materials, machined to exacting specification and heat treated where
practical for greater strength and longer life.
Rotary System of Drilling
Rotary drilling consists of a circulating system, rotation mechanism and a hoisting mechanism. The
circulating system consists of the mud pump, piping and valves, hoses and flow lines. The normal
circulating fluid is mud, which may be made up of many different substances and water. It is necessary
that the fluid be able to lift the cuttings from the hole and keep the wall of the hole intact to prevent
stuck drill pipe. The methods of controlling the properties of drilling muds are rather complete, especially
when deeper holes and core holes are drilled using water and depending on the bit mixing the cuttings to
The mechanism that rotates the drill pipe consists of a Kelly, drive rod, drive bushing, pins, quill and the
ring gear and pinion. The Kelly is a heavy wall, alloy tube which has three flutes milled lengthwise along
the outside diameter. These flutes act as a means of producing rotary motion and leaving the Kelly free to
move in the vertical direction. The drive bushing has a matching set of flutes on the inside diameter and
three floating, hardened pins are used to transfer the power from the drive bushing to the Kelly.
The hoisting mechanism consists of the hoisting drum, which contains a friction clutch and brake
mechanism and the cathead. As optional equipment, a sand reel drum may be furnished. The sand reels
are two types, that is, jaw clutch and friction clutch.
BBFL Consultants Ltd. currently staffs seven young, vibrant and productive engineers who support and
compliment the senior engineering staff. They are seen as permanent staff that will grow and develop
into competent and successful engineers and are afforded all the guidance and experience of the
directors. They are developing rapidly in our technologically biased environment.
BBFL Consultants Ltd. also staffs four technicians who handle our site inspections and supervision
requirements on a full time basis.
At the head office there are seven in‐house CAD workstations manned by experienced CAD technicians
and managed by Mr. Adelwyn Holder, our new Chief CAD Technician.
All workstations are networked to two central colour plotters and high speed colour printers for
Administrative support is provided by in‐house secretarial, accounting and clerical staff who are all
computer literate and are given the necessary resources to undertake duties for projects of all types and
