Structural Concrete 2020
Introduction
Structural Concrete 2020 sets a demanding challenge for all students studying structural design as part of UK
University BEng, MEng and MSc degree courses in Civil and/or Structural Engineering.
This year’s challenge…
The 2020 project is a high-rise residential building in a waterside
redevelopment area in a regional city centre. The building is to provide
two storeys of retail area with studio, one- and two-bedroom apartments
above, together with four two-storey penthouse apartments. Entrants
must respond as if they are part of the consultant’s team.
This student design competition aims to encourage interest and
raise competence in designing with concrete. The competition
offers a stimulating and fun challenge to students, while supporting
the curricula of civil and structural engineering departments of UK
universities. The main beneft for a student is in being able to present
their work to prospective employers, some of whom are involved in
setting and judging the competition. The national winners will be
presented with their prizes at an event in London where their award
winning entries will be shown. There will also be a sustainability award
for the student who demonstrates the best understanding of this
subject in their submission.
These awards reflect a signifcant commitment from the judges who,
together with The Concrete Centre, have carefully developed this
year’s competition. Initiative, creativity, aesthetic appreciation and
accuracy are called for, and will be assessed by the judges. Above
all, this competition has been designed to stretch the technical
competence of the students taking part.
Because it is so flexible, Structural Concrete 2020 can easily be
incorporated into existing university curricula, with content that
reflects an independent project, a group project or a module
assessment run over the frst, second or both semesters of the
academic year.

Structural Concrete 2020
1. Project brief: Monier Tower
A scheme is to be developed for a 22-storey residential tower in the waterside redevelopment area of a regional city
centre. The building has a one-storey basement and two storeys of retail area at ground and frst floor. The residential
tower, consisting of studio, one- and two-bedroom apartments, comes off a podium deck at level 2. One face of the
tower is sloping up to Level 18. Level 18 is a garden level with a smaller four-storey block rising from the garden level,
housing the two-storey penthouse apartments.
The new tower is situated on a prominent site in a redevelopment area
close to the waterside within the site of the old docks. Any external
concrete should be considered to be in exposure class XS1 to take account
of the seaside location.
The basement car park is accessed via a ramp in the north west corner of
the site and needs to provide 30 car parking spaces and 60 bicycle parking
spaces. The car parking is to be solely for the use of the residents of the
tower, and will not be used by the users of the retail space.
The retail space on the Ground and Level 1 should have columns at a
minimum spacing of 8m and have a floor to ceiling height of 4m. Access
between the Ground Level and Level 1 should be completely separate
from both the access to the car parking in the basement and the access
to the residential units above. It should consist of two lifts, one stair core
and two escalators. These are to be located in suitable positions within the
space.
Access between the basement and the residential levels will be via an
access core containing one staircase and two lifts, one of which is to be
a fre-fghting lift. The top penthouse levels will have a communal lift
and a staircase, with internal staircases between the floors within the
penthouses.
The architect has provided a typical layout for the apartments at Level 9
and for the penthouse levels. The other levels will be similar although as
the north facade is sloping, the layouts towards the top of the tower will
be modifed to suit the smaller area. The number of apartments per level
will therefore reduce on the upper levels. Structure can be placed within
the walls shown on the architect’s plans and in the external walls.

2. Design data
Verifcation of structural viability should be carried out in accordance with current Eurocodes. Entrants should clearly
state the documents used in support of calculations. Materials specifcations should be defned to current British
Standards.
Fire resistance of two hours is required.
Concrete is inherently suited to tall construction, with the many benefts
that concrete can provide including fre resistance, thermal mass,
acoustic separation and robustness. The Shard, London, is the tallest
building in western Europe, at 87 storeys and 306m . © Alamy
2.1 Loadings
Cladding:
• Precast concrete cladding including glazing 2.0kN/m2
Imposed loadings:
• Car parking 2.5kN/m2
• Retail 5.0kN/m2
• Residential 2.5kN/m2
• Circulation 5.0kN/m2
• Podium deck 10.0kN/m2
• Garden deck 10.0kN/m2
• Roof 2.5kN/m2
These loadings include an allowance for services.
All values are characteristic values.
2.2 The site
Exposure conditions
The site is flat, 0.5km from the sea. The value of fundamental basic wind
velocity, Vb,map, should be taken as 23.5 m/sec (based on BS EN 1991-1-
4:2005). Snow loading may be neglected.
Ground conditions

Ground water level should be taken as 1.0m below ground level.

3. Submission requirements
The submission is to comprise four components:
3.1 A conceptual design report.
3.2 An appendix containing design calculations to
verify the viability of the selected scheme.
3.3 Drawings.
3.4 An outline sustainability plan.
The submission must not exceed 60 single sided A4 pages
and three A3 size drawings. Two copies are required.
3.1 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:
i. An appraisal of two distinct and viable design solutions in structural
concrete for the building, together with their associated beam,
column and wall layouts. The appraisals should include sketches
showing the stability of the tower, the structural wall and column
locations, the structural elements and some brief notes on
construction methodology.
ii. An evaluation of the merits and disadvantages of the two solutions.
The evaluation should identify signifcant differences such as
cost or buildability between the two alternatives, and make a
recommendation in favour of one solution.
iii. 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.
iv. An outline specifcation for concrete and reinforcing materials,
including that for the foundations.
vi. A method statement for a safe construction procedure for the building.
vii. A statement of how robustness to avoid disproportionate collapse is
satisfed.
viii. After completion of your design, the client writes to you suggesting
that an additional staircase from basement to level 17 is provided
as a secondary exit path in the case of fre. Write a letter to the client
outlining how this might modify your design.
3.2 Verifcation of
structural viability
The verifcation of structural viability of the selected scheme should be
demonstrated in Appendices to the conceptual design report to make
up the balance of the report. (The maximum total length of the design
report, sustainability report plus Appendix is 60 pages A4.)
The Appendices should contain sufcient 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 clearly understand 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.
Note: calculations are not required for stairs or cladding.
3.3 Drawings
A total of three 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.
Two of the A3 drawings should be used to present general arrangements,
sections and elevations of the building to show the layout, disposition
and dimensions of structural elements for estimation purposes. Drawings
should be to an appropriate scale and must be dimensioned. Reinforcement
details should not be shown on these two drawings.
The third drawing should show:
a) the reinforcement detail where one of the columns supporting the
tower meets Level 2;
b) the reinforcement detail at the top of the basement wall where it
connects to Ground Level;
c) the detail of the fxing arrangement for a precast concrete cladding
panel on the tower.
3.4 Sustainability report
The Client requires a statement about the sustainability aspects of the
project. Prepare a section on the structure to go into the statement,
including any mitigating measures taken in the specifcation of the
structure, and covering some of the wider aspects of sustainability such
as fre, material efciency and resilience.
