Summary of Assessment Requirements

Assessment Task 2 focuses on developing competency in interpreting building drawings, specifications, and compliance documentation within the CPC40320 Certificate IV in Building Project Support (Contract Administrator). Students must work with the provided drawings, specifications, and industry guides to complete four major components.

The assessment includes:

Part 1 – Short Answer Questionnaire
Students interpret architectural drawings from a proposed two-storey duplex to identify construction features such as orientation, datum point, internal room dimensions, roof pitch, slab type, FFL/RL levels, and standard building abbreviations.

Part 2 – Door and Window Schedule
Based on the same drawings, students prepare detailed schedules listing door and window types, sizes, heights, and classifications.

Part 3 – Specifications
Students must:

• Develop a written process for comparing drawings with specifications prior to tendering.

• Provide guidelines for resolving discrepancies between drawings and specifications.

• Prepare written specifications for Bedroom 1 and the Ensuite based solely on linings, tiling and fittings.

Part 4 – Hand-Drawn Sketches
Students review the proposed extension drawings and apply the Livable Housing Guide to produce:

• A 2D plan view sketch of a wheelchair-accessible bathroom.

• A 3D elevation sketch of a wheelchair-accessible kitchen.
  Sketches must include measurements, reference notes, and relevant NCC citations.

The assessment emphasizes correct interpretation, compliance with Australian standards, and application of livable housing design principles.

How the Academic Mentor Guided the Student Through the Assessment

The academic mentor approached the assessment systematically, ensuring the student understood both the technical content and the required method of completion. Guidance was delivered in structured steps aligned with the four parts of the task.

Understanding the Assessment Sources and Context

The mentor first directed the student to review all essential documents, including drawings, specifications, the Livable Housing Guide and the Assessment Guide instructions.
The mentor highlighted the importance of relying only on Australian standards and avoiding overseas internet sources. The student was instructed to familiarise themselves with drawing legends, title blocks, symbols, conventions and the standards referenced in the textbook.

Interpreting Drawings for Part 1

The mentor demonstrated how to read the duplex drawings by beginning with the site plan, floor plans and elevations.
Key steps included:

• Locating orientation arrows and datum points

• Reading internal dimensions and slab thicknesses

• Interpreting elevation callouts to determine ceiling heights

• Identifying FFL/RL values from the sections

• Recognising abbreviations and verifying meanings using the legend

The mentor encouraged the student to use scale rulers, follow drawing cross-references, and double-check measurements across multiple diagrams.

Preparing Door and Window Schedules for Part 2

The mentor explained the structure of a typical door and window schedule used in industry.
The student was taught how to:

• Identify door symbols and tags

• Extract dimensions from floor and elevation drawings

• Determine whether each door was hollow core or solid core

• Cross-reference window types with elevation window codes

• Ensure all individual openings were accounted for

By reviewing examples, the student learned to present information clearly, as required in professional documentation.

Developing Specifications for Part 3

The mentor guided the student through the process of writing specifications by referring to the Sample Residential Specification and Topic 2 of the textbook.
The process included:

(a) Procedure Prior to Tendering

The mentor outlined the steps to compare drawings and specifications, including reviewing general notes, materials, finishes and measurements.
The student learned how this ensures accuracy and cost compliance during a tender process.

(b) Guidelines for Discrepancies

The mentor explained common conflicts between drawings and specifications and taught the student how to escalate these issues, document variations, and seek clarification before proceeding.

(c) Specifications for Bedroom 1 and Ensuite

The mentor showed how to extract linings, tiling, and fittings from the drawings and specifications.
The student learned to prepare concise but detailed specifications suitable for inclusion in tender documents.

Producing Hand-Drawn Accessible Design Sketches for Part 4

The mentor helped the student review the Livable Housing Guide, especially Gold Level requirements, and assess the existing bathroom and kitchen layout.
Guidance included:

• Calculating wheelchair turning circles

• Adjusting door widths to meet accessibility requirements

• Positioning shower, toilet, rails and fixtures for functional use

• Designing kitchen elevations with accessible benchtops, drawer heights and power point locations

• Annotating drawings with NCC references and relevant AS standards

The mentor emphasised accuracy in measurements and clarity in annotations to simulate real-world documentation.

Final Outcome and Learning Objectives Covered

By the end of the mentor-supported process, the student successfully completed all four assessment components with a clear understanding of industry expectations.

The assessment reinforced key learning objectives, including:

• Ability to interpret and extract information from architectural drawings

• Understanding of specifications and their relationship to construction documentation

• Skills in preparing schedules for doors and windows

• Knowledge of resolving discrepancies between drawings and specifications

• Competency in writing material and fitting specifications for residential spaces

• Application of accessible design principles for bathrooms and kitchens

• Ability to incorporate NCC references and livable housing requirements

• Development of documentation skills essential to the role of a Contract Administrator

The structured, step-by-step guidance helped the student approach the assessment confidently while meeting all competency standards required by CPC40320.
