Assessment Summary and Academic Mentor Guidance

Assessment Requirements

The assessment was designed to evaluate the student’s understanding of sustainable construction practices, safety measures, site analysis, and technical drawing skills across nine sessions. Each session covered a different aspect of construction knowledge and required both theoretical research and practical sketches.

Key Pointers to be Covered in the Assessment:

• Session 1: Ecological footprint awareness and sustainable material alternatives.

• Session 2: Hazardous materials, safer substitutes, and material safety (storage, transport, breathing, vision, contact, weight).

• Session 3: Site analysis at 1:200 scale, including sun movement, wind, noise, natural features, and soil class challenges/opportunities.

• Session 4: Converting 2D images into annotated 3D sketches at 1:5 scale.

• Session 5: Scaled 3D sketches of timber and concrete floor details at 1:5 and 1:20 with full annotations.

• Session 6: Engineered, composite, and steel sub-floor members with 1:10 sketches; wet area details at 1:20.

• Session 7: Wall sections through openings for clad frame, masonry veneer, and full masonry systems with annotations at 1:20.

• Session 8: Sections of concrete panels, aerated concrete, SIPS, straw bale, and ETFE systems at 1:20.

• Session 9: Roof-to-wall connections for truss and conventional roofs, and a box gutter detail at 1:20.

Mentor’s Step-by-Step Guidance

Session 1: Sustainable Awareness

The mentor began by guiding the student to calculate their ecological footprint and reflect on the number of Earths consumed. Next, they encouraged exploration of nature-inspired sustainable materials for residential construction, such as bamboo, rammed earth, and hempcrete.

Session 2: Material Hazards and Safety

The mentor explained how to identify hazardous materials (like asbestos, lead, and silica dust) and replace them with eco-friendly alternatives. Students were instructed to cover safety aspects systematically:

• Storage practices for safe handling.

• Transportation measures to reduce spillage/contamination.

• Impact on breathing, vision, and direct contact to highlight health risks.

• Manual handling safety by considering material weight.
  This session also required completion of a word document that detailed these aspects.

Session 3: Site Analysis and Soil Challenges

Students learned how to sketch a site at 1:200 scale and mark sun paths, wind patterns, noise zones, and natural drainage. The mentor guided them in identifying soil classifications and discussing challenges and opportunities for flat, moderately sloping, and steep sites.

Session 4: From 2D to 3D Sketches

The mentor explained how to interpret given 2D images and transform them into scaled 1:5 3D sketches with precise annotations. The focus was on visualizing structural depth.

Session 5: Floor Details

The session focused on producing timber floor details at 1:5 scale and concrete floor sketches at 1:20 scale. The mentor stressed accurate dimensioning and annotations, linking sketches to site classifications.

Session 6: Sub-Floor Systems and Wet Areas

Students were guided to research engineered, composite, and steel members and sketch them at 1:10 scale, noting size and placement. Additional guidance was provided for sketching wet area floor-to-wall junctions at 1:20, emphasizing waterproofing details.

Session 7: Wall Sections and Framing

This session required students to produce detailed sketches of wall sections through doors/windows for clad frame systems (timber, metal, PVC) and masonry veneer/full masonry systems. Mentors emphasized comparing framing materials and annotating structural and insulation components.

Session 8: Alternative Construction Systems

The mentor guided students to sketch sections of concrete panels, aerated concrete, SIPS, straw bale, and ETFE systems, all at 1:20 scale. The emphasis was on identifying unique characteristics and sustainability benefits.

Session 9: Roof and Gutter Details

Finally, students learned to sketch roof-to-wall connection details for both truss and conventional roofs. A box gutter detail at 1:20 was added, which was later replicated in a construction model.

Outcome and Learning Objectives Achieved

Through these sessions, the student successfully:

• Understood sustainable design principles and ecological impacts.

• Identified hazardous materials and proposed safer alternatives.

• Performed detailed site analysis and addressed soil challenges.

• Developed technical drawing skills with correct scales and annotations.

• Explored modern construction systems, including natural and engineered materials.

• Applied safety, sustainability, and structural knowledge in sketches.

• Demonstrated professional awareness of building standards and practices.

By following the mentor’s structured guidance, the student produced a comprehensive and well-annotated portfolio of drawings and reflections, showcasing their grasp of both practical construction detailing and theoretical sustainability concepts.
