8th August 2016
Brief Description
The purpose of this presentation is to give an understanding of the Methods, Plant and Sequence to construct an insitu concrete bridge.
This presentation can be used to engage Stakeholders and to get the Site Teams commitment to the programme. Also can be used for Induction Training and as a way to capture and share knowledge.
Project Execution Plan (PEP) details how a project will be executed, monitored and controlled. High in Educational Value and easily understood. Recommended for Continuing Professional Development (CPD)
This Presentation is innovative and has many beneficial uses.

Safe System of Work.
To provide a safe system of work is a legal requirement. What this means is that before you ask an employee to do a
job. You ensure that he has received training, has the appropriate personal protective equipment, the work area is safe
and he is unlikely to be injured or cause damage by carrying out the assigned task.
Project Management Plan for Health, Safety, Security and Environment. also Known as (HSSE Plan)
The Project HSSE Management Plan details how safety on site will be managed.
Project Procedures for Health, Safety, Security & Environment
Details the safe way to undertake a task
Methods Statements
Are prepared in advance of starting work, to plan a Safe System of Work on site for all activities that carries a risk. The
contents of a Method Statement, typically include:- Scope & Location of the Works, Programme, Roles & Responsibilities
of Staff. Resources, Work Methodologies and Risk Assessment.

Safety Risk Assessments
Are prepared to identify and evaluate risks, to adopt control measures to reduce or eliminate risks.
COSHH Sheet
The purpose of the Control Of Substances Hazardous to Health sheet is to identify how to prevent or adequately control
workers exposure to hazardous substances.
Permit to Work.
Is a management system used to control high risk activities by ensuring safety measures are in place prior to starting
work.
Types of work for which permits will be required include:
Excavation and the digging of trenches.
Working at height, including on roofs.
Working in confined spaces, for example entering a manhole.
Hot work, which is welding, soldering or cutting steel with angle grinders or by gas torch.
