Below is a ready-to-use project report template and an example Pugh-chart + justification you can copy into a word processor. Replace placeholders with your project’s details, sketches, and data.
Title Page (one page)
- Title: [Name of build]
- Project Engineer(s): [Project Engineer: First Last — list each person and include the words “project engineer”]
- Organization / Class: [Optional]
- Dates: [Project start date – completion date]
- Version: [Optional]
- Contact info: [email / phone / instructor]
Table of Contents (one page)
- List each page title exactly as in the report and the page number.
Example:
1. Title Page — 1
2. Table of Contents — 2
3. Problem Statement — 3
4. Brainstorm Sketches — 4
5. Pugh Chart — 5
6. Design Justification — 6
(Adjust page numbers when finalizing.)
Header and Footer (applied on all pages except where you prefer otherwise)
- Header (left or centered): [Name of build] — Title page info repeated (e.g., Project Engineer(s): Jane Doe)
- Footer (right or centered): Page numbers (e.g., Page 3 of 6)
- Make sure the title page info appears in the header on all pages as requested.
Problem Statement Page (one page)
- Page title: Problem Statement
- Problem Statement (concise): Describe the problem being solved — who, what, when, where, why, and how success will be measured.
Example: “Design a lightweight, low-cost bridge model that spans 60 cm and supports 5 kg for 30 seconds without permanent deformation. The model will be used for classroom testing.”
- Criteria (minimum list of measurable success criteria): list and briefly define each.
Example:
- Strength: must support ≥ 5 kg for 30 s
- Weight: ≤ 300 g
- Cost: ≤ $25 in materials
- Build time: ≤ 4 hours
- Safety: no sharp edges
- Constraints (limits/requirements): list constraints (materials, budget, time, size, fabrication tools, safety, rules).
Example: Uses only balsa, glue, and toothpicks; must fit within 70×20×20 cm envelope.
- Supplies (materials and quantities): list every supply needed to build prototypes.
Example:
- Balsa sheets (5 mm) — 2
- PVA glue — 1 bottle
- Sandpaper, ruler, hobby knife, clamps
Brainstorm Page(s)
- Page title: Brainstorm / Concept Sketches
- Include 3 or more unique sketches (hand-drawn or CAD screenshots). For each sketch include:
- Sketch label: Concept A, Concept B, Concept C, etc.
- One-line concept summary.
- Key features and expected trade-offs (strengths/weaknesses).
- Example (text descriptions to convert to sketches):
- Concept A — Warren truss bridge
- Features: repeated equilateral triangles, distributed load path, efficient in-bending.
- Strengths: good strength-to-weight, simple repetitive members.
- Weaknesses: longer cutting/assembly time.
- Concept B — Arch bridge with deck
- Features: curved arch transfers load as compression to abutments.
- Strengths: very strong under uniform load.
- Weaknesses: harder to fabricate; geometry-sensitive.
- Concept C — Beam with I-section using layered balsa
- Features: concentrated beams with flanges and web.
- Strengths: easy to build; strong in bending.
- Weaknesses: heavier for similar span.
- Concept D — Cable-stayed mini bridge (optional)
- Features: central mast, tension cables to deck.
- Strengths: visually simple, uses tension well.
- Weaknesses: needs strong anchors; complex assembly.
Pugh Chart Page
- Title: Pugh Chart / Concept Selection
- Explain method: choose a baseline concept (often current best or easiest to build). Compare other concepts to baseline across at least four criteria. Use symbols: + (better), 0 (same), – (worse). Optionally assign numeric scores (+1, 0, -1) and sum.
Example Pugh Chart (text table)
Baseline: Concept A — Warren truss bridge
Criteria: Strength | Weight | Cost | Ease of Build
Header: Concept | Strength | Weight | Cost | Ease of Build | Total
- Concept A (Baseline) | 0 | 0 | 0 | 0 | 0
- Concept B (Arch) | + | 0 | – | –
- Concept C (I-beam) | – | – | + | +
- Concept D (Cable) | 0 | + | – | –
Translate symbols to numeric values for totals (+: +1, 0: 0, -: -1) and sum:
- Concept A total = 0
- Concept B total = (+1) + (0) + (-1) + (-1) = -1
- Concept C total = (-1) + (-1) + (+1) + (+1) = 0
- Concept D total = (0) + (+1) + (-1) + (-1) = -1
Interpretation: Highest total is Concept A (baseline, 0) tying with Concept C (0). If tie, use secondary factors (safety, aesthetics, build time, risk) or rank criteria by importance and re-evaluate with weights.
Notes on Pugh usage:
- Use at least 4 criteria as you requested; you may include more.
- You can weight criteria (e.g., Strength ×3, Weight ×2) if some are more important — show weights and compute weighted totals.
- If you pick a different baseline, repeat comparison or convert to absolute scoring (1–10) per criterion and compute weighted scores.
Design Justification Page (one or more pages)
- Title: Design Justification / Final Selection
- Begin with a clear statement: which concept you selected and why.
- Use all criteria in your reasoning: explicitly address each criterion and explain how the chosen design meets them better than the alternatives.
- Contrast with other models: for each rejected concept, say which criterion(s) caused it to be rejected.
- Address risk and mitigation: identify main risks and how you’ll reduce them (e.g., joint reinforcement, test iterations).
Example justification (concise):
- Selected design: Concept A — Warren truss bridge.
- Reasoning by criteria:
- Strength: The Warren truss distributes loads through triangular elements; analytical estimates and small mockups showed predicted capacity > 5 kg with low material use, while the arch required precise geometry and the cable design risked anchor failure.
- Weight: Truss provides the best strength-to-weight ratio; the I-beam option required additional material and exceeded our weight limit in estimates.
- Cost: All options are low-cost; however, the arch and cable designs require extra jigging and hardware, increasing cost marginally.
- Ease of Build: Truss uses repetitive members and simple joints, allowing consistent quality within the 4-hour time constraint. The arch is more complex to shape and the cable system needs tensioning hardware that we do not have.
- Conclusion: Because the truss meets or exceeds all criteria with acceptable risk and low cost, it is the best choice. We will prototype a one-span truss, reinforce joints with gussets, and conduct incremental load tests to validate the design.
- Contrast summary: Arch — excellent strength but high fabrication risk; I-beam — easier to fabricate but heavier; Cable — elegant but high risk due to anchoring and tension control.
Appendix (optional)
- Detailed calculations (strength, bending, factor of safety)
- Material cost breakdown
- Step-by-step build instructions
- Photos of prototypes and tests
- CAD files or PDFs of sketches
Formatting and final checklist
- Ensure title page info appears in header on each page as required.
- Put page numbers in footer on each page.
- Table of Contents page numbers must match final pagination.
- Include at least 3 unique sketches (text plus images/drawings) in the Brainstorm section.
- Pugh Chart must include at least 4 criteria and 4 build sketches (I provided 4 concepts in the example).
- Provide a written justification that references every criterion and contrasts choices.
If you want, I can:
- Create a filled example for a specific build (give me the build name and any constraints).
- Produce a printable Word or Google Docs-ready version of this template.
- Convert the example Pugh chart into a weighted numeric scoring table tailored to your prioritized criteria.
