Introduction:
The objective of this assignment is to build 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.

Concept Design of Stadium:
• 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

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.

Construction Material:
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).
