* 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.

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 stopandthink.ca 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 Theater.
* 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.
