Building a Seawall
1.
Wave energy of the Wave.
Wave energy =1,260.6*(wave height
2
)
Wave energy=1,260.6*3
2
Wave energy=1,260.6*9
Wave energy=11,345.4 joules/m
2
Total Energy of the Wave.
Total energy=Wave energy*surface area
Total Energy=11,345.4*(8*300)
Total Energy=11,345.4*2400m
2
Total Energy=27,228,960 Joules

b)
The material combination chosen is Steel and Concrete.
Steel and concrete complement each other when it comes to their respective strengths and
weaknesses and hence, they would make a great combination. Both steel and concrete are
durable and readily available. Even though steel may be affected by corrosive agents like
2
weather, the concrete would act as a good cover against such agents. Factoring the strengths
of both steel and concrete it would take a very long time to break the seawall by waves.
On cost matters, this combination can be expensive in the short run but very cheap in the long
run hence there would be no need to carry out recurring maintenance and repairs to the
seawall: this ensures cost effectiveness for the long term. Further, this combination possesses
the ability to be molded into different shapes and sizes with ease to come up with a very
strong sea wall.
3.
The information that there was once recorded a 5m high wave does not greatly affect the design since a safety factor has already been put in place when designing. A safety factor would mean that when calculating the average heights of the waves as 3m, 5m height was factored for.
Seawall Proposal.
Design Bid.
In response to your request for bids for the design of a seawall project, we are happy to offer
this proposal. We recognize how crucial it is to build a sturdy seawall to safeguard your
coastline, and we are thrilled about the chance to provide our knowledge to this project.
Our scope of works will include; First, a very thorough assessment of the coastline in regards
to the total wave energy, the soil properties as well and the possible impact of the project to
the environment. Secondly, the detailed design concepts that respond to the specifications of
the assessed coastline as well as the selected combination of construction materials. Thirdly
we will provide very detailed structural engineering drawings which have factored in the site
specifications and finally we will offer construction project management services to ensure
that the project meets the design specifications as approved.
The construction of the
600m
Seawall is projected to take a period of 100 working days and will be able to withstand waves of at least 45 million Joules.
The proposed seawall is projected to work for a period of at least 45 years
without major failings.
