CPCCST3017 — Construct stone arches

1 Plan and prepare.

• 1.1Read, interpret and apply stone arch construction requirements from current plans, specifications, standards and codes.
• 1.2Follow relevant information from workplace procedures, workplace safety and environmental documentation.
• 1.3Calculate material quantities required for the task.
• 1.4Determine job priorities and sequence job tasks in consultation with others on site.
• 1.5Identify potential hazards and determine and implement control measures.
• 1.6Select and check condition of plant, equipment and tools and report damage or faults to relevant person.
• 1.7Check conformity of materials against the specifications and place materials in preparation for the work.

2 Set out arch.

• 2.1Select, fit correctly and use personal protective equipment (PPE) appropriate for job.
• 2.2Measure width and height of arch and transfer dimensions to arch support material.
• 2.3Mark striking point and create arch.
• 2.4Cut and assemble arch support allowing for ease of release on completion without jarring stonework.
• 2.5Mark central keystone and voussoirs onto arch support.
• 2.6Set out base, bond and gauge of stone arch.

3 Construct arch with regularly cut stone.

• 3.1Mix mortar to colour and consistency to meet job requirements.
• 3.2Construct arch columns level and plumb and maintain gauge to springing line of arch.
• 3.3Raise arch support and brace level across springing line and crown.
• 3.4Cut keystone and voussoirs to pattern with even joints.
• 3.5Lay stones with even joints maintaining bond and alignment with stone face.
• 3.6Rake joints to specified style and depth.

4 Construct arch with irregular stones.

• 4.1Set out and mark keystone to crown of arch.
• 4.2Construct arch using random rubble or random squared ashlar to match curved extrados.
• 4.3Match stones to abutting stones and lay selected stones using mortar joints maintaining alignment and plumb.
• 4.4Remove excess mortar, finish joints to specified profile and depth.
• 4.5Clean and brush stone face work.

5 Construct an arch with irregular voussoirs forming stepped extrados.

• 5.1Check delivered pre-cut voussoirs/wedges for conformity to design and order.
• 5.2Position keystone of archway centrally and lay voussoirs around centre to form arch.
• 5.3Lay regular stones where voussoirs are designed to correspond with courses.
• 5.4Lay random regular stones where voussoirs are not designed to correspond with courses.

6 Clean up.

• 6.1Clear the work area, and dispose of, reuse or recycle following workplace and environmental requirements.
• 6.2Clean tools and equipment, check for serviceability and report damage or faults.
• 6.3Store and secure tools and equipment following workplace procedures.

What does an assessment tool for CPCCST3017 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for CPCCST3017 needs to address all 52 unit components: 6 elements with 31 performance criteria, 4 performance evidence requirements, 16 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for CPCCST3017?

Auditori pulls the current release of CPCCST3017 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for CPCCST3017 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing CPCCST3017 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of CPCCST3017, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
