Title
Optimise timber for fibre and grade recovery
Level
4
Purpose
Credits
15
People credited with this unit standard are able to: demonstrate
knowledge of fibre and grade recovery for timber; make
optimising decisions for cutting timber; implement optimisation
decisions for fibre and grade recovery when cutting timber at

Explanatory notes
1
The following apply to the performance of all outcomes of this unit standard:
a All work practices must meet recognised codes of practice and documented
worksite health and safety and environmental procedures (where these exceed
the code) for personal, product, and worksite health and safety, and must meet
the obligations required under current legislation, including the Health and Safety
in Employment Act 1992, the Resource Management Act 1991, and their
subsequent amendments.
b All work practices must meet documented worksite operating procedures. This
includes the recording (by electronic or non-electronic means) of activities,
events, and decisions.
c All evidence of communications gathered in relation to this unit standard must be
in accordance with worksite procedures for content, recipient, timing, and method.

Definitions
Corrective action may include actions such as communication to management,
communication to on-site technical support person, communication to off-site
technical support person, cleaning, communication with maintenance staff,
recalibration, or changes made to the operating system in accordance with worksite
documentation.
Input material refers to timber, shook, or boards that are presented to the docking or
trim centre for further processing.
Optimise refers to the most efficient use of product and plant, taking into account raw
material input, customer demands, and machine capability.
Worksite policies and procedures refer to documented policies and to documented or
other directions provided to staff. These include, but are not limited to – ways of
managing health and safety, environmental considerations, quality, and production,
and must conform to legislation. Examples include standard operating procedures,
company health and safety plans, on-site briefings, and supervisor’s instructions.
Outcomes and evidence requirements
Outcome 1
Demonstrate knowledge of fibre and grade recovery for timber.
Evidence requirements
1.1
Cutting plans and product output mix are described in relation to input materials
and product demand in accordance with worksite policies and procedures.
1.2
Processing constraints are identified and potential solutions to maintain worksite
productivity and quality requirements are described.
Range
1.3
constraints may include but are not limited to – markets, timber
supply, preferred products, downstream processing options.
Impacts of poor decision making on fibre and grade recovery are described and
related to potential effects on customer demand and saw centre efficiency.
Range
customer demand and saw centre efficiency may include but is not
limited to – shipping on time, customer preferences, saw centre
productivity, volume of input material required, undesirable product
generation.
Outcome 2
Make optimising decisions for cutting timber.
Evidence requirements
2.1
Input material checks are completed to ensure material meets specification and
production run expectations in accordance with worksite policies and
procedures.

2.2
Individual pieces of input material are inspected for defects and their impact on
the cutting decisions is described with reference to constraints outlined in
evidence requirement 2.1.
2.3
Cutting decisions are selected based on the results of the inspection, and the
decisions are made, in accordance with worksite policies and procedures.
2.4
Trial pieces are cut and checked to ensure that the results predicted in evidence
requirement 2.3 are achieved.
Outcome 3
Implement optimisation decisions for fibre and grade recovery when cutting timber at
production speed.
Evidence requirements
3.1
Hazards associated with optimising timber for fibre and grade recovery are
identified and actions to be taken to isolate, minimise or eliminate the hazards
are described in accordance with worksite policies and procedures.
Range
3.2
hazards may include but are not limited to – moving equipment,
moving and misaligned pieces, kick back, sawdust, mobile plant,
noise.
Safe work practices associated with optimising timber for fibre and grade
recovery are identified and used in accordance with worksite policies and
procedures and legislative requirements.
Range
practices may include but are not limited to – isolation procedures,
lock-outs, emergency stops, machine guarding, wearing
appropriate safety equipment.
3.3
Cutting plans are implemented to optimise fibre and grade recovery in
accordance with worksite policies and procedures.
3.4
Production rate and product quality specifications are met in accordance with
worksite policies and procedures.
3.5
Product flow is managed to optimise downstream processes in accordance with
worksite policies and procedures.
Outcome 4
Monitor output timber when cutting timber for optimum fibre and grade recovery.
Evidence requirements
4.1
Output timber and output data are monitored for grade and size, and corrective
action is taken to optimise fibre and grade recovery, in accordance with worksite
policies and procedures.

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA,
before they can report credits from assessment against unit standards or deliver courses
of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies
to this standard are outlined in the Consent and Moderation Requirements (CMRs). The
CMR also includes useful information about special requirements for organisations wishing
to develop education and training programmes, such as minimum qualifications for tutors
and assessors, and special resource requirements.
