Structural Concrete Competition 2022: submission requirements

The submission is to comprise four components:

  1. A conceptual design report
  2. Appendix 1 containing design calculations for the selected scheme superstructure
  3. Appendix 2 containing the drawings of the selected scheme superstructure
  4. Appendix 3 containing a sustainability report.

The submission must not exceed 60 single sided A4 pages and three A3 size drawings. Only one copy is needed.

Conceptual design report

A maximum of 30 pages, of either 1.5 line spaced text in a maximum 11pt font, or neatly hand written in black ink, which should include:

  1. An appraisal of two distinct and viable structural solutions for the construction, together with their associated column/wall layouts. The appraisals should include sketches with supporting notes outlining the intended load transfer mechanisms, framing and stability functions, and the construction methodology.
  2. An evaluation of the merits and disadvantages of the two solutions. The evaluation should identify significant differences such as cost or buildability between the two alternatives, and make a recommendation in favour of one solution.
  3. A description of the structural solution adopted for the ground floor slab and a rationale for the selection.
  4. A description of the structural solution adopted for the suspended slabs and a rationale for the selection.
  5. A description of the foundation scheme adopted for the preferred solution, with a rationale for the selection. A fully detailed design for the foundation scheme is not required.
  6. An outline specification for the structural concrete and reinforcing materials to be used.
  7. A method statement for a safe construction procedure for the building.
  8. A statement on the robustness of the building to avoid disproportionate collapse.

Verification of structural viability

The verification of structural viability of the structural scheme should be demonstrated in the appendices to the conceptual design report to make up the balance of the report.

Appendix 1 should contain sufficient design calculations by hand to establish the form and size of all structural elements for the chosen scheme. Entrants should decide how best to convey this information within the space constraints imposed.

Calculations for individual elements should enable a checker to understand clearly their contribution to the strength and stability of the whole structure, and the load paths assumed. Hence, if computer output is presented, validation by (approximate) hand calculations is also required. Consideration should be given to performance at both serviceability and ultimate limit states.


A3 drawings should be included. Drawings may be prepared using appropriate CAD software, or by hand. In either case, notes and dimensions should not be smaller than the equivalent of an 11pt font. Drawings should be to an appropriate scale. The drawings should show the following:

  1. General arrangement of the foundation scheme
  2. General arrangement of the ground floor
  3. General arrangement of the first floor
  4. General arrangement of the roof
  5. Section through the building
  6. A section through the walkway showing the connection to the bridge
  7. The junction of the ground floor with the external wall in the classroom block.

Sustainability appraisal

There are number of high-level sustainability and environmental requirements.

Sustainability requirements:

  1. Optimise passive design measures (e.g. use of daylight and natural ventilation).
  2. Reduce the demand for energy and water use.
  3. Minimise waste.
  4. Provide opportunities for recycling.
  5. Minimise embodied carbon in the construction.

Environmental requirements:

  1. Daylight design producing a balanced, glare-free luminance across the classrooms and displaces electric lighting energy consumption.
  2. Thermal mass, night cooling and cross ventilation is used to prevent summertime overheating.
  3. Ventilation has heat recovery in winter and does not cause cold drafts.
  4. Acoustics providing good listening conditions, with classrooms easily upgradable so that children with hearing impairments can be taught.
  5. Buildings should be energy and water efficient and easy to monitor.

Other consultants are part of the contractor’s team and will be covering some of these points in more detail, but you have been asked to prepare a short report (maximum three single sided pages) for the contractor, discussing how your structural design helps to satisfy these requirements. This will form part of the contractor’s bid documentation.
