Introduction
The aim of this report is to evaluate major works that are involved in installation of the steel
boardwalk along the Liffey River and consequently to investigate what hazards and risks are
associated with them. The process will include identifying the people who are exposed to the
danger, proposing control procedures that would prevent the accidents happening and
designating persons responsible for the implementation. In addition, the sequence of work
and resources needed to carry out the task are going to be described. Consequently, the
information gathered from the analysis of the above aspects will be combined in the Risk
Assessment and the Method Statement that will terminate the assignment.
Task Description
The duty of the contractor is to carry out the installation works of the steel boardwalk along
the Liffey River in Dublin. The construction site is located in the central area of very busy
city what can cause serious disturbance to works. It is limited to the footpath and one line of
the Eden Quay road. The remaining lines of the road cannot be closed due to high traffic
flow. The site must be fenced off and the temporary traffic diversion signage must be erected.
Scope of works
The boardwalk steel structure will be bolted in to the existing concrete surface at the edge of
the river. Before erecting the actual steel frame, the fixing anchors must be first put in place.
In order to do so, some of the concrete barrier wall will require demolition for allowing
operators to fix the anchors and bolt in the panels. After completing this task, the process of
fixing sections of the steel jetties can begin. The jetties are manufactured on-site from the
delivered steel members. Each section of the board walk will then be lifted by crane and
transported to the desired position where workers can securely bolt them in to the ground.
The process will repeat for each section of the boardwalk.

Materials and equipment required
In order to complete the task of the steel boardwalk installation the following materials and
equipment will be required:
 Steel members- these will be used as a material for assembling sections of the
boardwalk as per drawing demonstrated bellow. It is important to point out that the
cutting and welding will be carried out on site.
Figure 2 - Site View
Figure 3 - Boardwalk section

 Mobile welding unit - is essential for the process of manufacturing the boardwalk on
site. The equipment complies of two bottles installed on the trolley; one contains
oxygen and another fuel gas (acetylene). Both gasses are delivered by hose to the
igniter (WWS, 2012)
 Generator- A single phase portable diesel generator is essential for power tools
operations such as demolition, assembling the boardwalk sections and installation of
the anchors. (EGD, 2012)
 Grinders- Heavy duty angle grinders require single phase power supply. The model
used on site is suitable for cutting and grinding steel. In addition, the abrasive wheels
especially designed for these operations must be provided. (Direct Industry, 2012)
 Drills and hammer jack- heavy duty drills are required for installation of the fixing
anchors and demolition operations. The power will be supplied by the single phase
3kW generator.
 Slings- are to be provided by the crane subcontractor. The inspections for wear and
tear prior the work commencement will be an essential part of the risk control
process.
 Fixing Anchors- Heavy duty, selected by the structural engineer anchors to be
provided.
 XCMG 80 ton Crawler Crane- On this particular
project where the construction space is limited and the
site is spread over a long distance, it will be reasonable
to use mobile crane. The XCMG80 model features
operations such as traveling with load and 360 slewing.
The length of main boom is 13-58 m and the length of
fixed jib is 9-18. This type of crane offers much more
mobility than the wheeled cranes. In addition, it does
not require stabilizers to set-up what limits the needed
space and time in comparison to wheeled mobile crane.
The unavoidable condition that contractor is obligated
to provide for safe lifting operations is stabilized and
well compacted ground. This is already in place in form
of asphaltic road surface. (XCMG, 2012)
 Foam Life Jackets, Harnesses and Inertia Reel – are to be provided to all workers
performing tasks at the edge of the river bank. As in regard to the inertia reel, the
double anchorage will be used with the purpose of enhancing the security of
workers.(SGS, 2012)
Figure 4 – XCMG80

Risks involved in performing the task
According to Cooke and Williams (2009, p.125), the ‘health and safety risk arises from the
impact of hazards. Where there is no hazard there is no risk, but in construction there are
hazards everywhere on site’
The main hazards and risks assigned to this project are illustrated in the table below.
Moreover, the Figure 5 will describe method of classifying the most dangerous risks, where
the level of likelihood and severity of accidents is ranked highlighting the areas that require
additional control. The ratings of hazards will later be included in the method statement and
risk assessment. All of these actions will allow for deciding who is exposed to the danger.
Subsequently the foundations for outlining the precautions and control methods will be
provided. Also, the contractor will have to appoint the person responsible for implementation
of the findings on site.
The Major risks identified on the steel boardwalk installation are:
Hazard Risks
Use of power tools  Faulty tools
 Electrocution
 Injuries
Welding  Burns
 Radiation
 Explosion
Working at the
edge of the river
 Slips
 Falls
 Drowning
 Injuries
 Hypothermia
Crane set up  Crane collapse
 Deaths
Lifting materials  Falling materials
 Deaths
 Injuries
Manual handling  Back injuries
 Slips
Working in the
city centre
 Public entering the site
 Road accidents due to traffic diversion
Figure 5 - Hazard Rating Table

Control measures
One of the major risks identified on this project is falling from the edge of the river bank.
Therefore, contractor has decided to use inertia reel system to eliminate the risk. It is
important to mention the pendulum effect that results from inappropriate use of the system.
The nature of Pendulum effect is presented by the figure below. To avoid the danger of
falling employee hitting the ground or falling into the cold river, the secondary anchorage
will be used.
In addition to inertia reel system for works at the edge of the river bank, the permit to work
will be implemented. This is a specialized system for ensuring that potentially very dangerous
work is done safely and the method statement is properly and formally implemented. Its
fundamental principle is that certain defined operations are prohibited without specific
permission of responsible foreman. The permition being only granted once stringent checks
have been made to ensure that the necessary precautions have been taken and that it is safe
for work to go ahead. (Hughes and Ferret, 2005)
Another major risk is lifting steel the steel panels. The 80 tonnes crane will be hired.
Therefore the responsibility for safeguarding work involving carnage lies partially with sub-
contractor. However some control procedures must be identified. Prior to start any lifting
works, the certification of the subcontractors’ plant and crane operators’ ticket must be
inspected. Also, the slings must be checked by competent person for signs of wear and tear.
Under no circumstances lifting operation should take a place in adverse weather conditions or
by operator under influence of alcohol or drugs. If no other problems were identified the
works can proceed. Handling the lifted materials is only to be performed with use of tie-in
lines operated by experienced employees with permit to work at the edge of the river.

Workforce required
To perform the task the following staff will be required:
 Competent foreman
 Qualified welder
 4 general operatives (2 with experienced in lifting materials)
 Experienced banksmen
 Crane operator
People responsible for overseeing and signing of the task
The person in duty of controlling safety plan on site is foreman and employees carrying out
the operations themselves. However responsibility for overseen and planning the safety
controls on site is a responsibility of the contractor.
Introduction to Risk Assessment
The main objectives of this risk assessment are to determine the measures required by the
contractor installing the boardwalk to comply with health and safety legislation, and thereby,
reduce the level of occupational injuries and ill-health. (Hughes and Ferrett, 2005) The risk
assessment will cover all those who may be at risk, such as employees, subcontractors or
members of the public. The document will be compiled in accordance to The Construction
Safety Handbook published in Ireland (Curley, 2006).

Conclusion
This assignment increased the general knowledge about the process of preparation health and
safety risk assessment and method statement for the construction projects. The task given in
the project brief was to investigate the formworks for assessing construction works and
identifying related to them hazards. This required obtaining the universal guidelines provided
by HSE for identifying, evaluating and managing risks. In addition, the literature review has
further outlined the importance of these documents. Edwards (1995) points out that the
accidents in construction are unforeseen events, which can have the most significant effect.
Therefore, the aim of the risk assessment was to ensure that such risks are managed
effectively, where the method statement is a formal written document detailing how an
activity is to be undertaken (Hughes and Ferrett, 2005). The methods statements are not
required by statue, however together with the risk assessments they form a crucial part of the
site safety management system (Cooke and Williams 2009).
On the basis of the above arguments, it was understood that spending time on planning and
preventing the risks is worth of making an effort. Hence, the words of Sir Brian Appleton
from the Piper Alpha Disaster (1990) emphasise the meaning of the conclusion; ‘Safety is not
an intellectual exercise to keep us in work. It is a matter of life and death. It is the sum of our
contributions to safety management that determines whether the people we work with live or
die’. This is to say that the risk controls identified in the risk assessment and method
statement can save not only human lives, but also can stabilize the companies’ well-being.
Nevertheless, it is important to understand that these documents will not remove all the risks
on the project, thus both the client and contractor must recognise that residual risks will
always remain regardless of what preventions are made.
