3. Prepare project schedule for irrigation installation and construction

3.1. Construction operations are prepared in sequence.

3.2. Operations are entered into a manually prepared schedule or computer based software package.

3.3. 'Critical path' is identified and schedule revised with new activities/projects, as needed, and documented.

3.4. Timeframe is adjusted to take account of anticipated delays.

4. Determine all the required resources for project

4.1. Temporary services and site accommodation is determined as required.

4.2. Plant requirements and dates are selected and accessed.

4.3. On site labour requirements are determined.

5. Prepare dilapidation report

5.1. Records are made of the condition of existing building(s) to be retained and structures on the adjacent site boundaries.

5.2. Copies of reports are submitted to adjacent building owners prior to commencing construction.

EVIDENCE GUIDE 

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:

• identify operational requirements from contract documentation
• develop strategies and plan procedures for installation and construction
• develop a project plan with tasks, responsibilities, timelines and costs.

Context of and specific resources for assessment 

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.

RANGE STATEMENT 

The range statement relates to the unit of competency as a whole.

Planning may include:

• the planning of installation and construction work for both gravity fed and pressurised irrigation systems.
