Steven Macdessi - Occupational health and safety management plans

By Steven Macdessi

A person with control of a construction project where five or more persons are working, or are likely to be working, simultaneously on a construction site must ensure that:

(a) a site-specific occupational health and safety management plan is prepared before the work commences; and
(b) the plan is monitored, maintained and kept up to date during the course of the work.

The person with control of the construction project must ensure that the occupational health and safety management plan includes:

(a) a statement of responsibilities, listing the names, positions and responsibilities of all persons who will have specific responsibilities on the site for occupational health and safety;
(b) the detail of arrangements for ensuring compliance with the occupational health and safety induction training requirements of this national standard;
(c) the detail of arrangements for the co-ordination of health and safety issues of persons engaged to undertake construction work;
(d) the detail of arrangements for managing occupational health and safety incidents when they occur, including the identities of and contact details of all persons who will be available to prevent, prepare for, respond to and manage recovery from such incidents;
(e) any site safety rules, with the detail of arrangements for ensuring that all persons at the site, whether employees, contractors, suppliers or visitors, are informed of the rules;
(f) the hazard identification, risk assessment and risk control information for all work activities assessed as having safety risks; and
(g) the safe work method statements for all high-risk construction work.

The person with control of the construction project must ensure that a copy of the occupational health and safety management plan is available for inspection throughout the course of the construction work by:

(a) any person engaged to undertake construction work at the site;
(b) any person about to commence work at the site; and
(c) an employee member of an occupational health and safety committee, an occupational health and safety representative, or a person elected by persons employed at the site to represent them on health and safety matters.

The person with control of the construction project must ensure that any person engaged to carry out construction work at a construction site is provided with a copy of all relevant parts of the occupational health and safety management plan for that site before they commence work.

If an occupational health and safety management plan is changed during the course of construction work, the person with control of the construction project must ensure that all persons engaged to carry out construction work at the site concerned are promptly provided with a copy of the changed parts of the plan of relevance to their work.


SAFE WORK METHOD STATEMENTS

A person with control of a construction project must ensure that:

(a) each person with control over high-risk construction work, including sub-contractors and self-employed persons, gives the person with control of the construction project a written safe work method statement for the high-risk construction work to be carried out, before commencing that work; and
(b) all such safe work method statements are kept up to date and reviewed whenever there is a change to the high-risk construction work.

A person with control of the construction project must ensure that there are arrangements for:

(a) ensuring that all persons undertaking construction work to which a safe work method statement applies comply with the safe work method statement; and
(b) when a person is not complying with a safe work method statement, they are directed to stop work immediately and not to resume work until the safe work method statement is complied with, unless an immediate cessation of work is likely to increase the risk to health and safety, in which event they must be directed to stop work as soon as it is safe to do so.

If no other person is responsible for the preparation of a written safe work method statement for high-risk construction work, the person with control of the construction project must:

(a) prepare the written safe work method statement;
(b) keep the statement up to date and review it whenever there is a change to the high-risk construction work;
(c) ensure that the work is carried out in accordance with the statement; and
(d) ensure that when there is non-compliance with the statement, work is stopped immediately, or when it is safe to do so, and not resumed until the statement is


OCCUPATIONAL HEALTH AND SAFETY TRAINING

The following applies to apply to all persons with control of construction projects, all persons with control of construction work and all persons undertaking construction work, with the exception of:

(a) visitors to a construction site who are accompanied by a person who has received occupational health and safety induction training; and
(b) persons temporarily at a construction site to deliver plant, supplies, materials or services where a risk assessment indicates that any risks to such persons can be controlled through other measures.

A person with control of a construction project or control of construction work must not direct or allow another person, including a self-employed person, to carry out construction work on the construction project unless the person with control is satisfied that the other person has undertaken occupational health and safety induction training.

Persons engaged to undertake construction work must not do so until they have completed occupational health and safety induction training and training identified in the risk assessment for the work to be undertaken.

A person with control of a construction project or control of construction work must retain records for a reasonable period after the completion of the construction project of the occupational health and safety induction training and any other training given to persons directly engaged or trained by them to undertake construction work on the project.

Work Breakdown Structure WBS by Steven Macdessi

WORK BREAKDOWN STRUCTURE (WBS)

WHAT IS MEANT BY THE TERM “WORK BREAKDOWN STRUCTURE” (WBS)?


A complex project is made manageable by first breaking it down into individual components in a hierarchical structure, known as the work breakdown structure, or the WBS. Such a structure defines tasks that can be complete independently of other tasks, facilitating resource allocation, assignment of responsibilities, and measurement and control of the project.

This logical subdivision of all the work elements is easy to understand and assimilate, thus helping the project participants to quantify their responsibility and position in the overall project. Work not in the W.B.S. is outside the scope of the project.

As with the scope statement, the W.B.S. is often used to develop or confirm a common understanding of project scope. Each descending level represents an increasingly detailed description of the project elements.

MEANS OF SUBDIVISION
The overall process of construction can be divided and sub-divided for management purposes into various elements or groupings,
Trade or Sub-Contractor Groupings,
Building Element (Product),
Location on site,
Material Types,
Sequence, (recognizing dependencies)
Organizational
Contractor's contractual responsibilities,
Cost Centre (Cost Planning Quantity Surveyors)

This division and subdivision process is referred to as “decomposition”
Decomposition involves the breaking down of major project deliverables into smaller more manageable components until the deliverables are defined in sufficient detail to support future project management actions, planning, executing, monitoring/reviewing and attendance where needed.

ADVANTAGES OF WBS
a) provides for easier monitoring of work definitions,
b) allows work to delegated in coherent packages,
c) enables work to be managed progressively,
d) enables the enhancement of cost effectiveness, productivity & process improvement,
e) allows for Risk to be managed effectively,
f) provides a system for training,
g) demonstrates objective evidence of planning.

DISADVANTAGES OF WBS
a) Requires active management of the interfaces created,
b) Management functions increased with each definition, e.g., planning, organizing, monitoring and reviewing/changing.
c) Risk of demarcation problems with every interface created.

HOW MUCH DETAIL?
There is always a question with WBS as to the amount of detail to be shown.
Too much detail and it becomes unmanageable and expensive, but too little detail does not permit the accurate estimation of time, cost and resources, as well as the practical management of tasks.

The manager must rely on judgment and experience when deciding the appropriate amount of WBS detail.

WBS ROLL-UP
The roll-up process is used to roll back up project activities for management overseeing purposes. By initially suitably arranging the WBS, re-combining of the boxes can produce an overview of the project.
This roll up technique lends itself to anything that flows in the project, such as costs, duration, man-hours, productivity, resources (such as materials), etc. Any of these could be planned, tracked and controlled using W.B.S.
