Design Process 7.


Engineering Design – Structural Design

Feasibility exercise

After a concept is agreed and when determining the fixture’s construction, the engineers and designers should carry out a joint feasibility exercise and review critical expectations (financial, structural and aesthetics)


  1. Review concept and agree timeline to include prototype review and testing
  2. Set electrical specification (standard and performance)
  3. Carry out predesign H&S analysis and set criteria
  4. Set structural objectives – performance, lifespan and function
  5. Ensure easy access to connections
  6. Avoid ‘specials’ and utilize standard platforms where possible to ensure maximum flexibility
  7. Adopt a design approach that maximizes longevity and reduces the need for replacement parts during the required life of the fixture
  8. Optimise material usage (reducing waste)



  1. Minimise the use of less ‘eco-friendly’ materials
  2. Ensure that the unit is fully de-constructible at the end of its useful lifespan
  3. Use mechanical fixings that facilitate deconstruction
  4. Specify ‘knock-down’ construction where feasible to optimize shipping / transport / dismantling efficiencies (balance against costs and installation time)
  5. Avoid composite materials and bonding materials together
  6. Where possible use renewable materials derived from a certified source (e.g. FSC)
  7. Preferably use minimal, reusable, and recyclable packaging
  8. Re-use existing equipment and components in the new design if feasible
  9. Priorities materials with a high recycled content
  10. Specify materials which are commercially recyclable


Design format

It is crucial for retailers to have complete drawing packs and full specification data, in digital form, for all fixtures.

This facilitates swift and accurate design, development and procurement choices.

To meet increasingly demanding Health & Safety requirements and to protect customers, our business, and our suppliers it is essential to provide all supporting documentation in digital format

A complete set of digital technical drawings and specifications allows retailers to promptly provide all suppliers with identical information resulting in equal tender conditions.

Being able to instantly access complete and up-to-date information, via a common portal will help all businesses to operate in a professional, cost effective  and competitive manner.

Structure drawing

The following is a list of the minimum information required to complete technical drawing sheets.

All drawing dimensions, notation & information must be legible when printed on A3 paper size.

All sheets must have a drawing boarder that includes:

  1. Display code
  2. Project name
  3. Drawing description
  4. Drawing number
  5. Drawing creation date
  6. Drawing revision (in ascending alphabetic order, initial drawing issue must be revision ‘A’)
  7. Scale
  8. Sheet number & total number of sheets in the drawing pack
  9. Materials & finishes (i.e. surface finish, coating, colour reference & gloss level)
  10. Supplier name
  11. Suppliers address and telephone number and website
  12. Drawn by

Third party and ‘off the shelf’ items must be clearly identified and marked with the appropriate supplier details, including:

  1. Supplier name
  2. Item description
  3. Reference number

First sheet

  1. Perspective or isometric view of assembled unit
  2. No dimensional information required
  3. Revision history stating:
  4. Current drawing revision
  5. Sheet numbers affected
  6. Revision descriptions
  7. Revision dates
  8. Drawing numbers of related parts or assemblies

General assembly & sub assembly sheets

  1. Plan, front & side elevations of the assembly in third angle projection.
  2. Sectional elevations if needed to aid understanding.
  3. Rear & underside elevations are optional, but should be included when useful.
  4. All elevations must be drawn to the same scale
  5. Isometric view of the assembly drawn at the same scale as main elevations if possible.
  6. Overall dimensions of the assembly
  7. Dimensions of assembled counterparts & any other references viewed as important or useful
  8. Fixing details (e.g. Fasteners required, welding details etc)
  9. Performance criteria (e.g. maximum shelf loading).
  10. Assembly & manufacturing instructions
  11. Drawing numbers for related parts or assemblies that are detailed in separate files/folders.

Exploded assembly sheets

  1. Exploded isometric view of the full assembly.
  2. BOM (Bill Of Materials) table numerically identifying each part. Including:
  3. Numerical identifier
  4. Part number (if available)
  5. Part description
  6. Drawing number (if available)
  7. Quantity

Individual part drawing sheets

  1. Plan, front & side elevations of the assembly in third angle projection.
  2. Sectional elevations should be included wherever relevant to aid understanding.
  3. Rear & underside elevations are optional, but should be included when useful.
  4. All elevations must be drawn to the same scale.
  5. Fully dimensioned, including:
  • Angles
  • Thicknesses
  • Radii
  • Hole specifications
  • Critical dimensions (with tolerances applied).
  • Drawings of folded metal parts must include an additional flat pattern elevation, with overall dimensions, drawn at the same scale as the main elevations.
  • Fixing details (e.g. Fasteners required, welding details etc).
  • Multiple show materials, which should always be located on the last page, can be collated onto one sheet. Each identified by name or part number with any shop fitting & display aid codes also displayed.
