Unit of Competency PMC552051C - Finish green concrete products
Description This unit of competency covers the process of finishing green concrete products. It involves preparing and finishing surfaces and identifying and resolving process malfunctions.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit of competency applies to operators in a concrete plant who are responsible for finishing green manufactured concrete products before they have been cured. The unit covers all finishes applied to concrete before curing (e.g. exposed aggregate) and assumes that all manufacturing operations up to final vibration and/or screeding the top surface flat have been covered by other units of competency. This unit includes:operation of concrete mixersmeasuring of ingredients and additivesinterpretation of formulae/mixing specificationsmatching concrete to specificationfinishing concrete to match samplesspraying concrete to make exposed aggregateapplying sealers and curing compounds to wet concretethe operation of all ancillary equipment. This competency is typically performed by operators working either independently or as part of a work team.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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

The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency.

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

It is essential that the process be understood and that the importance of critical material properties, mixing variables and surface finishing techniques is known. Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action.

Consistent performance should be demonstrated. In particular look to see that:

surface finish matches specification and is consistent

coverage is adequate and consistent

sealer coverage is adequate and consistent.

Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency.

Context of and specific resources for assessment

Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations.

Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.

Simulation or case studies/scenarios may be required to allow for timely assessment of parts of this unit of competency. Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions.

Method of assessment

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units.

Individual enterprises may choose to add prerequisites and co-requisites relevant to their processes.

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assignment, checklist) and due date here

(add new lines for each of the assessment tasks)

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Required skills include:

recognising conditions which will lead to out of specification product

implementing the enterprise's procedures within time constraints and in a manner relevant to the conducting of operations

conveying information relevant to the operation clearly and effectively

reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes:

principles of concrete mixing (if mixed by operator)

principles of veneer adhesion

principles of concrete finishing

distinguish between causes of faults such as:

material inconsistencies

mixing irregularities

finishing difficulties

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Procedures

All operations are performed in accordance with standard procedures and work instructions

Surface finishes

Surface finishes may include:

fine wood float

rough wood float

hand steel float

broomed

helicopter steel float

raked finish

Surface finishes may be applied before or after veneering

Surface finish after veneering may then also require further finish after curing

Typical problems

Typical problems may include:

off colour batches

bleeding between concrete mixes

consistency of veneer and cover

consistency of spray pattern

adequacy and consistency of surface finish

wet patching of surface finish

Occupational health and safety (OHS)

All operations are subject to stringent OHS requirements and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and OHS requirements, the OHS requirements take precedence

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
