Introduction:
In this assignment for building a football stadium for the Qatar 2022 world cup the
mechanical and electrical assessment of materials that are needed to be used are described in
details and the calculations of the strength and quantity of materials and electrical
components are done that will ensure stability for long time and safety of people inside the
stadium. The constructional components of the stadium such as the various load bearing
materials, the types of concrete that can be used are hypothesized and the breaking points of
those are represented to select the most suitable and safe items for the construction. The
properties data of the different materials from different published papers are collected to form
the performance graphs with each and in addition the audit of electrical energy required in
different electrical components that will be installed throughout the stadium is shown here.
Part 1:
The entire design of the football stadium will be carried out in a total of eight stages
as described below.
Pre-concept design: Collecting data from different sources to do the analysis of the chosen
site and the confirmation of the requirements.
Concept design: Developing the details of the design for determining the required
construction materials and the extra structures that are needed.
Schematic design: The design of the whole stadium including major structures, gates and
electrical components using a software like AutoCAD or else.
Calculation and development: Calculating the mechanical and electrical specifications of the
different structures and components and then choosing the best fitted equipment for the
design.

Date issue: Issuing a date for starting the real construction of the stadium. Selection of well
experienced tender before date of issue is recommended to ensure no delay in the date of
issue.
Task 1a:
Now, to construct a stadium it may take from approximately 18 months to 3 years
depending on the size of stadium, climate condition and unexpected events while ongoing
construction process. The generalized way of starting the construction is to construct a
seating bowl through site excavation that can be of 50 feet deep or more. Then the masonry
work is performed with manufacturing the components and installing them in planned places.
After the initial phase the lights are installed, concession areas, restrooms, locker room,
portable toilets are installed. As the football stadium is prepared for the world cup, hence
there should be enough green grass in the field for players’ comfort and improved playing
condition. Now, as natural grass requires suitable soil conditions to grow which may not
available in chosen site, installing artificial grass can solve the problem at a lower cost and
minimized injury of players.
The entire football stadium can be separated mainly in four parts namely Activity area,
spectators viewing area, spectators’ service area and parking area respectively. The schematic
diagram of the entire stadium is shown below.

Now, the most important phase of construction is to choose the concrete material for building
the structures. The general composition of any concrete is cement, coarse aggregate (like
screening and gravel), fine aggregate, chemical and water. The percentage of the different
composition of concrete are 7 to 17% of cement, 15 to 20% of water, 63 to 78% of aggregate
and 22 to 37% paste (mixture of cement and water).
The components and strengths of three 20 mm mix of cements are shown in the following
table.
