10. Methodology
10.1. Before Site Establishment
10.1.1.
A site
inspection must be carried out by a competent, experienced person. This
inspection should take into account the state of the piling platform, access to
the piling position by the rig, access to delivery vehicles, and the proximity
of any other structures, cables, and services which are considered necessary
for safe piling operations.
10.1.2.
These
recommendations should include work to be done to the piling platform to create
a firm-level surface, details of the proximity of structures and services, and
work required to allow access to the rig and delivery wagons.
10.1.3.
All
operators of the rigs will be suitably trained and experienced in the operation
of the rig.
10.1.4.
All
operators must be certified, competent, and experienced.
10.1.5.
All men
working around the rig will be suitably trained to ensure the rig man oeuvres
around the site safely with due regard to other machines, excavations, cables,
and other operatives
BEFORE WE MOBILISE WE MUST HAVE ASSURANCE
THAT THE PRINCIPAL CONTRACTOR/CLIENT HAS IDENTIFIED, LOCATED, AND PROTECTED ANY
AND ALL UNDERGROUND SERVICES.
10.2. Establishment
10.2.1.
Specification
for low loader and details of the intended task to be agreed upon and given to low
loader supplier.
10.2.2.
The
client’s site representative is to be fully consulted in advance on planned work
activities, time schedules, and personnel & work equipment involved, and
any relevant safety information exchanged.
10.2.3.
Employees are
to sign in at Site Office on arrival and receive site safety induction.
Employees will
sign out on departure from the site.
10.2.4.
Access
route and unloading area to be agreed upon and (as necessary) cordoned off at a
safe distance by barriers to prohibit unauthorized access by the public and other
contractors, and “no entry” signs displayed. The route will be kept clear and
free from obstructions and overhead or underground services. Visual safety
check carried out by an employee of [Company Name Here].
10.2.5.
If
possible, the rig is loaded from the rear of the trailer unit; loading is to
take place from the side of the area is restricted. Rig driver to comply with
directions given by banks man. Site traffic was prevented from passing the low
loader.
10.2.6.
When
securely positioned on the trailer, the rig is to be tied down securely to the
bed of the trailer, using suitable chains and strapping. All employees must
always wear suitable PPE and the site representatives kept informed of the progress
of work.
10.2.7.
The rig
and low loader are to be inspected by a “competent” employee to ensure the security
of the load.
10.2.8.
Low loader
to exit site, subject to agreement with Client’s site representative. Whilst
exiting the site onto public roads, clear traffic management is used at all
stages of operation.
10.2.9.
Road and
pathway to be cleaned and tidied; warning signs and barriers to be removed.
10.3. Driving Bearing Piles
10.3.1.
Request
‘Permit to dig’ before starting.
10.3.2.
Make sure
that there are no overhead obstructions and that the working piling platform
surface and access are appropriate for the safe operation of the piling plant
and that there are no underground services.
10.3.3.
Before the
commencement of piling operations, the following must be considered:
A.
Are piles
set out and a piling layout drawing provided?
B.
The
specific testing requirements have been identified.
C.
All
necessary authorities are aware of the commencement of piling operations.
10.3.4.
Before
pitching a pile the safety hook must be placed in position to prevent the
hammer falling if the winch brakes fail.
10.3.5.
The rig
should be established by tracking to the required piling position under
supervision from the driver and bank man. The mast of the rig should then be set
vertically over the pile position and checked using a spirit level accordingly.
10.3.6.
6. The
nominated pile having been brought to the piling rig by the forklift truck,
should be drawn towards the rig using the pile hoist rope using a 2-ton SWL sling
wrapped around the pile approximately 1m from the end of the pile. The sling
should be checked regularly for any defects.
10.3.7.
The safety
hook should now be removed and the pile section then lifted so the pile head
locates into the pile driving head of the hammer box on the rig.
10.3.8.
8. To
establish pile lengths, confirm durability and soil resistance and verify pile
design, probe piles in agreed working pile positions can be installed across the
site at the commencement of piling operations.
10.3.9.
A minimum
penetration of the pile toe should be obtained to fix the pile in the ground
dependent upon soil conditions and again the verticality of the pile should be
checked. The pile can then be driven to the needed criteria.
10.3.10.
When the
pile has been driven to a level of approximately 1.5~ 2m above ground level,
piling should cease temporarily whilst the hoist rope is disconnected. Once the
rope and sling are disconnected, piling can proceed.
10.3.11.
The pile
set will be taken by physically measuring the movement of the pile over a
required number of blows. The set of every pile will be measured at
installation and recorded on the pile record sheet(s). It is also a requirement
to carry out re-strike measurements on at least 1 pile to check the dynamic
resistance of the pile. Checking to see that there is no decrease over some
time, the re-strike must be taken over 5 blows. The scheduled initiatives
should be equal to or less than the equivalent set. Each re-strike is to be documented
on the pile logs. A pile penetration record sheet can be completed to if
necessary complement the pile sets. Once these operations have been accomplished
the same process is to be repeated on the following piles to be installed.
10.3.12. No personnel should be within the working
radius of the rig without a safety helmet or ear defenders. Within 8m the noise
level can be, subject to its surroundings, more than 85 dB, therefore ear
defenders must be worn. The rig has appropriate signage on the sides. If
personnel do not obey our exclusion zone work will be suspended, halted and the
main Contractor informed.
10.3.13.
All
necessary PPE should be worn ~ gloves, boots, a hard hat, and eye protection.
10.4. Dynamic Pile Testing
10.4.1.
Before the
commencement of pile testing, it shall be checked with both the rig driver and bank
man that the piles to be tested have not been cut or damaged.
10.4.2. It shall be of paramount importance that access
to the piles to be tested is suitable for the piling rig to avoid damage to
other installed piles.
10.4.3. Locating bolts will be drilled into opposite
faces of the pile to accept the accelerometer and strain gauges using a
cordless drill. Alternatively a pre-drilled “dolly”, can be used on top of the
pile, which saves time when testing more than 1 pile.
10.4.4. The gauges are connected to the analyzer
equipment via a signal cable.
10.4.5. The piling rig is set up on the pile.
10.4.6. Information on the pile to be tested is passed
to the independent testing engineers to calibrate the analyzing equipment.
10.4.7. The test is performed by delivering several
blows to the pile head using the installation procedure.
10.4.8.
A finalized
report will be forwarded to the client on completion of contractual terms.
10.5. Loading and Unloading Piling Rig and Heavy Plant On/Off Low
Loader
10.5.1.
Ensure
that the company supplying the low loader is aware of the size and weight of
the rig so that the low loader is operating well within its capacities.
10.5.2. Ensure the company supplying the low loader is
aware of the collection and delivery address in sufficient time for the delivery
route to be agreed upon by the relevant authorities.
10.5.3. Ensure that the low loader can safely reach the
collection point, having due regard to any overhead cables which may be fouled
by the rig when leaving the site.
10.5.4. Ensure that the low loader can safely reach the
collection point, having due regard to any underground services that may be
damaged due to the weight of the low loader itself, or the additional weight of
the rig once loading has been completed. Where it is probable that damage may
occur these areas shall be marked as restricted zones, using goalposts or
brightly colored markers.
10.5.5. The rig should ideally be loaded from the rear
of the trailer unit, but loading can take place from the side of the area is
restricted. The rig driver must take note of all directions given to him by the
bank's man.
10.5.6. When the rig is positioned on the trailer, to
the satisfaction of the low loader driver, it must be tied down securely to the
bed of the trailer, using adequate chains and strapping.
10.5.7. During the loading operation, it may be
necessary to prevent traffic, either public or site, from passing the low
loader. Again, distinct and clear signals should be used by the bank's man.
10.5.8. Upon the completion of all loading operations,
the rig and low loader must be checked over to ensure there are no loose items
such as packing, slings, tools, or timbers that could fall off during transit.
10.5.9. When satisfied that the rig is secure, the low
loader can then move from the site having checked, if required to do so, with
the necessary authorities.
10.5.10.
Whilst maneuvering
onto the roads it may be necessary to stop traffic, both public and site, by
the use of distinct and clear signaling.
10.6. Site Operations
10.6.1.
Before the
arrival on site, access should be checked to ensure there are no cables or services
(overhead or underground) obstructing the route of the low loader.
10.6.2. Before the commencement of any activity, the
unloading area should be subject to a visual check by the rig driver to ensure
it is free from any obstructions and a safe distance away from all excavations
and adjoining buildings. The ground should also be sufficiently firm and level
to allow the unloading to proceed safely.
10.6.3. Whilst maneuvering, and during the unloading
process it may be necessary to stop, or prevent traffic from passing too close
to the low loader, both public and site.
10.6.4. During unloading the rig driver must take note
of any directions given by the bank's man.
10.6.5. At all times during the unloading process, the
rig must remain in a stable condition, and be handled by a fully trained
driver.
10.6.6. Once the rig is off-loaded the low loader is
removed from the site, and after checking that the access from the unloading
area to the rigging area is sufficiently firm, the rig can be moved.
10.6.7. Clean up if necessary road or pathway.
10.6.8. If in town center police may have to be made
aware of movement times & route.
10.6.9. During all loading and off-loading operations,
all personnel should wear safety helmets, safety footwear, and high-visibility
clothing.
10.6.10.
The rig
and telehandler will be full on arrival therefore refueling should not be
necessary. But if required the plant will be re-fuelled by the Principle
Contractor’s procedures.
10.7. Offloading and Stacking of Materials
10.7.1.
The
unloading area shall be established and suitably prepared before the arrival of
any materials. The following shall be taken into consideration accurately and
safely:
-
The vehicle,
and or driver/operator will walk the route before offloading.
-
The site
access and route to the stacking area shall be assessed and established.
-
Paying
unique attention to ground situations, obstructions (buildings, excavations,
and many others), and services both overhead and underground that may be fouled
as a result of the burden of the loaded wagon.
-
Where
necessary goal posts or markers should be in use to indicate areas of danger.
-
Consideration
shall be given to the stacking area which shall be firm and level, and free
from obstructions. Where this is not possible suitable arrangements should be
made to ensure that the stacked piles are stable and adequately supported.
-
Where it
is apparent that the ground conditions in either or both of the above do not
present a suitable surface, then arrangements shall be made with the main
contractor to prepare the ground before any stacking or delivery of piles is
performed.
-
The site
surface can be determined by a site visit, and suitable arrangements made with
the client before arrival on site of any equipment.
10.7.2. To ensure the safe maneuvering of the delivery
vehicle once on site, the drop-off points should be placed in the most
practical position, about the following.
-
Be in such
a position to allow the delivery vehicle to exit the site safely either by
allowing enough room for a turning circle, or the reversal of the vehicle
without risk to the driver or other site personnel – use banks man.
-
Be a
sufficient distance from any excavations, buildings, or other obstructions that
may cause damage to the delivery vehicle or others – use banks, man.
-
Upon
arrival, the delivery vehicle shall be directed along the prepared route toward
the stacking area by the bank's man.
-
Under no
circumstances is the wagon to maneuver on site unite Piling Method Statement
