A concrete mix contains 5 major
elements: cement, water, coarse
aggregates, fine aggregates (sand) and
air in different proportion. Additional
elements such as pozzolanic materials (fly
ash, silica fumes or slag) and chemical
admixtures can also be incorporated to
the mix to increase its properties.
109. Stakeholders Engagement
Method of Work Plan (MOWP)
A Method of Working Plan (MOWP) is prepared when the normal operation of an aerodrome is
disrupted through aerodrome works and the risk to aircraft operations is increased. Stakeholders
likely to be significantly affected by the proposed works will be given the opportunity to participate
in the planning process.
The MOWP will clearly set out the following: • the scope of work and the stages of carrying out
the work; • how the works are to be carried out and the restrictions on the works organisation; •
how the aircraft operators and pilots will be told, through NOTAM, of the restrictions to aircraft
operations at each stage of the work; • identify any changes necessary to aerodrome markings
and lights as the works progress; • drawings to illustrate work arrangements and changes to
declared distances, taxiing routes, etc.; and • identify persons responsible for the works and those
accountable for ensuring safety of the aerodrome facilities to aircraft operations.

Health,Safety&Environment
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.

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.
