You are a Consulting Company, and have been asked by the Olympic Committee to submit proposals to win a contract to build the podium in the Olympic pool.
There have been several problems fitting the awards podium at the side of the pool.
The only place available, is in a corner.
However, space is limited. There is also
a problem with height restriction due to
the low roof in this space. The committee
want you to draw accurate plan and side
views, so they can check that the floor
space and height clearance are adequate
to meet risk assessments.
The best proposal wins the business prize
from sponsor’s!
