The document discusses traffic management plans for construction vehicles that require outriggers. It raises concerns that relying solely on slowing traffic and separating it from outriggers by 1.3 meters with bollards may not adequately control risks as required by law. Examples show outriggers being struck in accidents that collapsed cranes and injured workers. Additional controls like barriers or crash vehicles may be reasonably practicable to further reduce risks and meet duty of care obligations. Simply following traffic plans may not ensure risks are controlled far as reasonably possible as required.
A Longitudinal Channelizing Barricade (LCD) is a federally-designated type of traffic barricade. LCDs are designed to provide visual guidance for motorists and pedestrians. They do not provide positive protection. An LCD fills the void in safety between the hazard that concrete barrier posses to motorists versus the gaps in lines of drums that allow vehicles and pedestrians into the work zone!
This document discusses sight distance, which refers to the length of road visible to a driver at any time. It defines three types of sight distance - stopping sight distance, overtaking sight distance, and intersection sight distance. Stopping sight distance is the minimum distance required for a driver to stop safely without collision. Overtaking sight distance is the minimum distance required for a vehicle to safely pass another traveling in the opposite direction. Intersection sight distance allows drivers to see any hazards and stop if needed when approaching an intersection. The computation of sight distances depends on factors like reaction time, vehicle speed, braking efficiency, road gradient, and the speeds of multiple vehicles in overtaking situations.
The document discusses the design requirements for railings on Mn/DOT bridges. It covers the materials used for different types of railings as well as crash testing requirements. Reinforced concrete, steel, and timber are common materials, with concrete barriers being most common for traffic railings. Crash testing is required by the FHWA for bridges on the National Highway System and has established six levels of testing. The design of railings must consider safety, cost, aesthetics, and maintenance. Standard railing applications and non-standard railings used by Mn/DOT are presented in tables.

Nrt safety message 44 reduction in braking (wet rails)Garry Pepper
Reduced brake effectiveness was experienced by a Road Rail Vehicle (RRV) descending a wet gradient recently sprayed with water. The RRV appeared to experience brake lock up, skidding along the rail for approximately 90 meters before colliding with a stationary RRV. As a result, the following interim controls are implemented: RRV operators should not descend steep grades in wet conditions unless the track ahead is confirmed clear of people and equipment. RRV vehicles must maintain a safe distance of 250 meters when passing through wet areas, and reduce speeds to 10km/h on downward slopes. Any incidents of reduced traction, wheel slip or braking must be reported immediately.
In the United States an average of approximately 1,100 people die and 40,000 people are injured annually as a result of motor vehicle crashes in work zones. For addressing the safety in the work zones, a clear understanding of work zone traffic control devices and the dangers they pose to the drivers, pedestrians and workers should be obtained. This would be valuable for highway agencies in setting up proper traffic management plans based on the prevailing conditions. The purpose of this paper is to educate transportation departments, consulting engineers, and others on the safety benefits of Longitudinal Channelizing Devices as an alternative to drums and temporary concrete barrier for work zone traffic channelization. The results show that the acceleration of vehicles in case of water-filled longitudinal channelizing devices is much lesser than concrete barriers, hence, the former proves to be a much safer and efficient tool for work zone areas.

IRJET - Design, Simulation of Loadcells for Commercial VehiclesIRJET Journal
This document describes the design, simulation, and analysis of load cells for measuring weight on commercial vehicles. It aims to allow weight measurement of vehicles while in motion to prevent overloading. Load cells using strain gauges are designed and modeled in CAD software. A ladder frame chassis is selected to mount the load cells. A shear beam load cell design is analyzed in ANSYS to simulate stresses and deformation under loads. The simulation results show maximum stresses and deformations within material yield strengths, indicating the robust design can reliably measure vehicle weights. The system is intended to help enforce weight limits and improve safety by preventing overloading of commercial vehicles.
This document provides guidelines for inspecting and maintaining guardrail systems. It discusses guardrail basics such as barrier guidelines, clear zone distances, design options, and roadside obstacles that may require shielding. It also covers different types of barriers, including rigid concrete barriers and semi-rigid W-beam guardrails. Additional topics include length of need calculations, barrier placement considerations, terminals, crash cushions, and inspection and maintenance responsibilities. The goal is to help ensure all barrier installations are built and maintained according to current standards to optimize safety performance.
This document provides guidance on guardrail basics including:
- Barrier guidelines recommend installing barriers only if they reduce crash severity based on a benefit/cost analysis.
- Clear zones are unobstructed areas beyond the roadway for errant vehicles to safely recover, with minimum recommended distances based on design speed and traffic volumes.
- Design options for roadside hazards rank removal/relocation as the top preference over barriers or delineation only.
- Barriers like guardrails are intended to redirect vehicles from fixed objects or terrain features to reduce crash severity.

Similar to TRAFFIC MANAGEMENT AROUND VEHICLES THAT REQUIRE OUTRIGGERS FOR STABILISATION 2 (20)
2. In recent months the question of what constitutes reasonable and safe traffic management around
vehicles that require outriggers for stabilisation has been raised by stakeholders in the Victorian
construction industry.
Some employers and their representatives have indicated that a traffic management plan that meets
the Australian Standard AS1742.3 “Manual of Uniform Traffic Control Devices” and the Vicroads
“Worksite Safety – Traffic Management Code of Practice.,” is sufficient evidence for a safe system of
work.
In relation to both the Australian standard and the Code of Practice, each document makes reference
to the requirement for a duty holder to ensure the safety of workers and other persons so far as
reasonably practicable.
Below is an extract from AS1742.3
3. The reference in the Vicroads Code of Practice is equally clear and refers directly to the OHS Act
2004 and regulations.
The Code of Practice also places on the “Works Manager”, who can be taken to be the construction
company, an obligation to audit the traffic management plan and its implementation on the road to
confirm that it is working as required and to identify that all risks to employees and other persons are
being controlled so far as reasonably practicable.
As a result principal contractors who are relying on a traffic management plan that does not eliminate
or control the risk to site employees or the travelling public so far as reasonably practicable will be in
breach of the OHS Act 2004 and regulations
In the case of a traffic management plan being set up around any vehicle that requires outriggers to
stabilise it while it is in use, including mobile cranes, vehicle loading cranes (VLCs), or concrete
placement boom trucks, consideration must be given to the risks associated with the plant vehicle’s
outriggers being struck by a passing out of control vehicle.
A common practice when controlling traffic past vehicles with outriggers may be to slow vehicles to
40kmh, provide a separation distance of approximately 1.3 metres between the live traffic lane and
the outriggers of the plant vehicle, delineate this separation area with high visibility plastic bollards
and use traffic management employees holding stop/slow bats to control the flow of traffic if the road
has been reduced to one lane.
The question is:
Does this type of traffic management set up eliminate or reduce so far as reasonably practicable the
risks associated with other vehicles potentially striking the outriggers of a crane or concrete boom,
potentially destabilising the vehicle, resulting in a collapse?
Below are some examples where concrete placement boom pumps have become unstable and
collapsed causing serious injury. The mechanism or cause for the destabilisation and subsequent
collapse has not been defined for all examples, however, it is reasonable to say that should a vehicle
such as a car, bus or truck impacts upon a plant vehicle’s outriggers, even at low speed, the result
could likely be the destabilising of the plant vehicle followed by collapse.
4. Figure 1
A NSW Ambulance spokeswoman said a man, aged in his 30s, suffered serious injuries after he was hit by equipment
when the concrete boom pump collapsed. The construction worker was pouring concrete in a stairwell when the leg of
the crane snapped, sending it crashing into the brick wall above him. The man was knocked over by the rubber boom.
Figure 2
AN Orange building worker has been critically injured on a site in West Orange after being pinned under a concrete
pump boom that collapsed around 7.30am.
5. Figure 3
A SERIOUSLYinjured construction site worker was flown to hospital by CareFlight after the medical team rescued him
from freshly poured concrete on a building site near Camden late yesterday. The CareFlight doctor said the man, aged in
his 40s, suffered a severe scalp injury and blood loss, and then collapsed into a freshly poured concrete trench when hit
by the boom from a concrete pump.
When undertaking site inspections with a focus on the adequacy of traffic management, duty Holders
should assess the traffic management plan and road set up to ensure that the risks to plant using
outriggers have been controlled so far as reasonably practicable.
Any assessment should follow the auditing guidelines contained in the Vicroads Code of Practice and
should consider the following information contained in the code.
6. When using the audit/assessment criteria set out above in a typical situation where there is only a
separation distance of 1.3 metres and plastic bollards to separate live traffic lanes from plant vehicle
outriggers, it would be understandable for any person to form a reasonable belief that risks exist as a
separation distance and bollards do not prevent other vehicles impacting outriggers should the
following occur.
Other road users failing to comply with the implemented traffic management plan owing to
intoxication, distraction or illness.
Larger vehicles such as buses being on the road owing to public transport operations
Adverse road conditions owing to the weather
Traffic volumes during peak periods
Therefore, in reply to the question that was posed above, a separation distance and bollards is
inadequate protection for outriggers and does not control all the risks to employees and other persons
so far as reasonably practicable
If there is insufficient protection for vehicle outriggers and there is a risk to employees and other
persons from road users striking the outriggers, potentially collapsing the plant, then additional safety
controls must be implemented by the Principal Contractor to further reduce or eliminate the hazards
and associated risks even if those additional safety controls were not identified in the original traffic
management plan.
As a result it may be reasonably practicable for a Principal Contractor to implement the following
controls.
Install water filled plastic barriers in front of and adjacent to outriggers.
Establish a permanent loading zone protected with concrete barriers or steel crash
attenuation bollards installed into the road.
7. Park a traffic management crash attenuation vehicle on the approaches to the work zone.
Implement an Ironman barrier system. This system allows individual or small sections of
barriers to be raised onto an internal jockey wheel assembly allowing duty holders to simply
relocate barriers around sites without the use of any additional machinery.
CONCLUSION
The risk of serious injury to construction workers following the collapse of plant such as concrete
placement booms is well illustrated in examples above.
All effort must be made to eliminate outriggers being struck by passing vehicles thereby destabilised
the plant. These efforts must be made for duty holders to maintain their obligations under section 21
of the OHS Act 2004.
When assessing the workplace, duty holders should also consider observations about the work being
conducted, the location on site to where concrete is being pumped or items are to be crane lifted and
the proximity of workers to the concrete placement boom hose or the crane lifted loads.
Simply relying on a traffic management plan complying with the Australian standards or a code of
practice may not be good enough for a Principal Contractor to comply with sections 21 and 23 of the
OHS Act 2004.
