* Claybar Contracting has worked over 750,000 hours for IOES with 0 recordable
injuries over a 12 year period. The last three years (200,000 hours) have had no
reportable injuries on IOES sites.
As a result of a questionable item identified during an LPO, A specialized tool was developed to
manipulate 4 tonne corner posts during installation. These post were initially turned by hand placing
the labourer close to the top of the panel with their Hands in the line of fire. The immediate solution
was to use a crowbar to distance the labourer from the hazards. Additional hazards were further
identified in that the tool could slip throwing the worker off balance. A tool that locks into the channel
was developed with an adjustable length eliminating handling hazards (pinch points, exposure to burrs
and poor ergonomics) and putting the worker at a much safer distance from the excavation.
* Proprietary carbon filters placed inline
with the air conditioning/heating
system of the excavator. Eliminates
fumes from the cab providing a safer
environment for the operator. Also
provides a less visible form of
protection when operating in a
politically sensitive area where gas
masks may disadvantageous.
* Hazard ID provided the opportunity to
develop a floating platform for the
signaler to safely direct the operator
while excavating inside the sliding rail
shoring. The platform attaches to the
side of the sliding rail system
providing the signaler a safe enclosed
area directly in line with the
operators line of sight. Eliminates a
work at height situation as the
platform is enclosed with safety rail.
Ground screws were developed to eliminate the
need to place sand bags or used tires on top of
bio pile covers to hold them down. The screw is
driven into the soil with a half inch impact gun
and a 1” nut driver. The tarp is then attached to
the nut with a snap tie. Aesthetically more
pleasing on high profile sites and eliminates the
need to lift 50 lb. sandbags or 4o lb. tires. Also
solves the problem of tire disposal and soil
disposal once the life cycle of the bio pile has
been met.
* As a result of a
very successful LPO, this paraseal hanger was
developed (right) the previous method of installation is shown on
the left. The hanger eliminates the need for entry into excavation,
the need to work at height the requirement for two men to carry 80
lbs. of material across uneven ground and it also reduces
installation time by 500%. (30 minutes vs. 2.5 hours)
This bucket was developed as a result of a near
loss. The former practice was to load a
conventional bucket with gravel to provide
additional weight while striking the corner posts
to advance them into the ground. This practice
accelerated the deterioration of the bucket and
caused gravel to bounce out of the bucket and
spill to the ground (some pieces 6”in diameter) .
The new prototype has 4 additional tonnes of
steel as well as additional reinforcing side plates
and gussets. This bucket has lasted five years
with no sign of deterioration. As no material is
required in the bucket to provide additional
weight, the issue of bouncing rock is also
eliminated. Wear on the excavator has also been
reduced as the operator does not need to pound
on the posts as was required previously.
Site planning meeting offered the opportunity to work with the supplier to modify the
corner posts on the sliding rail shoring. Previous methodology required an access
agreement with the neighboring property owner (usually the city) and an
encroachment agreement as the system had to be placed one foot over the property
line in order to consume materials right up to the edge of property. This modification
eliminates the need to involve third parties as excavation can now proceed to
property line without overlapping. The City no longer needs to be involved for a road
cut permit so reporting concerns are also eliminated. City permits often require the
sharing of data as a condition of permitting. Modified post (right) original post (left)
During a site safety meeting, it was established that there was a lack of definitive Information with
respect to what level of hearing protection was required with certain tools. A robust best practice was
developed that used a chart with corporate equipment listed. The sound levels were recorded for the
operator and nearby personnel (figure to the left) including colour coded recommendations for the level
of hearing protection required. Stickers were also printed (figure to the right) that are affixed to
the appropriate piece of equipment as a reminder for the operator.
Mature, best in class Short Service Worker program. Each category focuses on appropriate
training modules for the respective risk associated with the type of worker. Workers are
registered on the website and progress is tracked electronically through
graduation. Mentors and mature site safety workers are registered as well.
* First example of remediation using excavation with dynamite in Canada. Over
60 explosions were used to reach depths of 45 feet in solid granitic bedrock.
Canada’s most traveled highway, the 401 was 40 feet away. Traffic was
maintained during the blasting process thru the use of a rolling road closure,
slowing traffic with one police vehicle while increasing the traffic gap with
another creating a 1 minute window to complete the blast.
* Demolition of Major Highway 401 site. 40,000 tonnes excavated including
breaking 2 meters of bedrock. Treated over 3,000,000 liters of impacted
groundwater back to the water table.
* Excavated 150,000 tonnes of soil to depths of 15 meters. Water table at 9
meters below grade. Completed during severe weather condition.
Remediation was progressed concurrently with the MTO’s contractor
constructing the new service center adjacent to the remediation site.
Southern Ontario's primary fiber optic line ran parallel to the excavation less
than 8 meters away. Disruption of the telecommunication was estimated to
have cost $5,000,000 per minute if interrupted.
* IOES and Asset management Joint
venture to restore the Historical
Danforth Theater. IOES and Claybar
were responsible to remediate the
site and partially demolish the rear
of the building. Asset Management
and Claybar constructed the new
facility and restored the Danforth
Developed a robust SharePoint website that
incorporates all aspects of the LPS. Near losses,
LPO’s and losses are submitted directly from the
field to the IOES project manager and Claybar.
Data from questionable items and root causes
are tracked in real time and statistics are
available immediately to all staff members.
OIMS documentation is available in a searchable
format to staff. Work permits are filled in live
online and status is tracked in the office.
Desktop reviews are preformed on all Work
Permits. Communication is instant with all
advisories posted same day as well as providing
a repository for WWGHLL and safety alerts.
* LPO’s and Near Loss forms
are completed in the field
electronically using InfoPath
forms. These form as are
then transmitted to both
IOES and Claybar in real
time. Data is tabulated upon
submission providing real
time tracking and trending
as well as V and V.
* The SharePoint site also contains a
comprehensive library using
InfoPath forms where field staff can
open edit and submit JSA’s for
archiving and review. Site specific
versions can be maintained along
with the base JSA.
