Our project was brought to us by Mauricio Gonzalez. We were informed that the school needed
ways to bridge high school sciences and college level sciences for the students by providing
them with a way to interact with the environment around the school. Our team conducted
research, examined the problem, and has now created a final solution.
The first section in our report includes our background research on the problem space. This
included researching the school, community, environment, logistics, and market. Research was
the best way for our team to truly understand the school, the community, and the needs of both.
Next in the report is our problem statement. We based our problem statement on our research
and our meeting with our client, Mr. Gonzalez. This statement identifies the key issues that must
be solved. These issues are lack of use of the surrounding environment, specifically the Harlem
River, the lack of a safe pathway down to the river, and the lack of a laboratory area by the river.
Following the problem statement is our design specifications. The design specifications address
what exact functional requirements must be fulfilled to solve the problems that were introduced
in the problem statement. By determining what functions and requirements our product must fit
into, our team in a sense created a roadmap of where the design should lead. This section also
includes design constraints and an estimated budget that had to be addressed before going
forward on a final design or actual construction.
The following item in our report is our final design. We have created what we feel is the best
possible design to solve the problems that the Frederick Douglass Academy is experiencing, due
to the constraints that we have encountered. Through our research of materials and dimensions,
we have created what we feel is most likely the best possible design for the jetty if everything
goes according to our plans.
Next in the report is a list of alternative solutions. If there are legal or cost constraints that will
not allow this jetty to be built, we want to provide the client with viable alternatives that will still
enrich the sciences at the school. We have come up with a list of other options that the school
could pursue rather than the jetty, if they so choose.
After the alternative solutions, we have included a section describing what future groups can do
to build on our work. Our client specifically told us that he was disappointed with the lack of
organization of other groups that he had worked with that the continuations were not smooth.
We have included as much information as possible to make the next group’s job as easy as
possible and to ensure a smooth transition.
At the end of our report, we have attached several project documents. These include our Gantt
chart of scheduled dates, our Product Design Specification chart, and our list of resources. We
also included several pictures of our visit to the school that will allow another group in the future
to see the area and better understand what they are working with.
We enjoyed working on the project with our client and wish him the best of luck in finishing it.
Through our research, we have been able to determine a great deal about the students at
Frederick Douglass Academy and the neighborhood of Central Harlem. Approximately 80% of
the students at FDA reside in the Harlem area. There are nearly 1,500 students at the school,
ranging from grades 6-12. Graduation and college attendance are expected of all students. The
school is about 52% female and 48% male. The racial breakdown is 72.5% African American,
26.5% Hispanic, and only 1% White, Asian, and Indian. To attend Frederick Douglass
Academy, a student must apply, present two written recommendations, and have an interview. If
accepted, the student is subject to rigorous academics and a large workload. The scores on the
Regents exams are 30-40% above the average in New York City. Students also are able to take
Advanced Placement classes in Calculus, Statistics, Physics, Chemistry, English, French,
Spanish, American History, and European History. The vast majority of students at the
Frederick Douglass Academy are very well prepared, high achieving students who continue on to
college and succeed in life.
In contrast, the neighborhood of Central Harlem is one of the most impoverished in all of New
York City. The neighborhood is home to 151,113 people. The neighborhood is almost
completely minority group, with a scarce 8% of the population being Caucasian. The median
household income is $21,508, almost half of the national median household income. There is a
9.8% unemployment rate, and 36% of the population is living under the poverty line. A third of
the adults did not graduate high school. The neighborhood is 26% children 17 and under, who
often do not have the opportunity to succeed due to their poor living conditions and lack of
support. The health statistics of Central Harlem are appalling. About a quarter of the residents
say they feel like they are in poor health. The number of deaths due to AIDS in Harlem for
every 100,000 people is 3 times the number in New York City, as well as the number of drug
related deaths is 2 times as large. The four most common causes of death are Heart
Disease/Stroke, AIDS, Cancer, and violence, almost all which with preventative measures or
proper screening could be avoided. 30% of adults in Harlem are smokers, and even though over
half are trying to quit, adults’ actions can still heavily influence minors’, and many begin
smoking every day. These statistics on the demographics of Harlem are nearly opposite those of
Frederick Douglass Academy. This information shows how much this school really is doing for
children who may have no other chance in life without a good education, and it makes the project
we have seem even more worthy and important for these kids.
The Harlem River is a major part of the geography of our project that is essential to research and
understand. The Harlem River is approximately eight miles long and separates Manhattan from
the Bronx. It is an open river, meaning there are no fees to boat or row on the river. There are
several problems the Harlem River has that are relevant to our project. The water contains some
toxic residues. There is also a large risk for oil spills, due to the number or boats on the river.
However, since we will not be building into the water, but nearby, these issues do not appear to
hinder our project. Another important issue to consider is the wildlife located near the School
and the Harlem River. There are many different types of animals that live in the city. Some of
these animals include pigeons, cockroaches, rats, squirrels, mice, opossum, flies, raccoons and
mosquitoes. We must use the information about the types of animals that could get onto and
destroy or damage the jetty and the walkway to set up proper coverings and protective layers. It
is most likely nearly impossible to keep all of these creatures out, but we can create a design that
is capable to keeping almost everything out.
The jetty walkway should consist of a covering that is resistant to snow and rain, or other adverse
weather. The walkway is covered by FDR Drive, eliminating the need to build an overpass. Also,
the area of land that we initially hoped to build on will be owned by a private tennis club within
the next year, making extensive building near impossible. However, after consulting with Dr.
Hodge, the principal of the school, about building a structure for storage along with a river
access point, we were told that we would have little trouble receiving permission.
In our research, we have identified three main legal issues that must be resolved in order for the
project to continue. These issues include New York City zoning regulations, New York State
environmental regulations, and Federal Transport regulations. The zoning regulations in NYC
are for the most part there to give restrictions on a new building on city land. Our designs have
avoided any building on MTA property, and instead building a simple structure on, eventually,
private property near the river. A future goal would be contacting the Department of
Environmental Conservation in determining what types of sampling and monitoring will be
appropriate in the Harlem River. Because the Harlem River is a navigable waterway, technically,
there are federal transport regulations that must be met. However, the jetty will not protrude into
the water, only the probes. Therefore, environmental contacts should be the next objective for
groups working on this project in the future.
The market for our product is the school and the students in it. We feel that the teachers would
be able to make good use of the jetty for experiments in the sciences. We must not only build
the jetty, but convince other teachers that there are benefits to the students in using it for hands
on learning. We also feel the students are an important group to market to. Students often reject
what they find unfamiliar, so it is important to provide an understanding of the benefits of such a
project so that they can embrace a tangible explanation for what they read about in textbooks
every day. Another group that we feel could also benefit from the use of a jetty is the Boys and
Girls Club of America. There are several Boys and Girls Club’s in New York City, and in
particular, two are very near to the water. However, the distance between these clubs and the
water remains under city property, so we would have to do additional research to find if there are
different regulations and if it is at all possible for this type of jetty to be used by the organization.
If the jetty can be built in order to provide access to the river, students would develop a more
technical understanding of the biological sciences, while also tangibly working with the concepts
that they have been studying all throughout grade school.
Formal Problem Statement
Our team did not initially grasp the true problem at Frederick Douglass Academy from reading
the problem statement. The client’s overview of the project was thorough, but we were unable to
completely understand the problem that Frederick Douglass Academy was experiencing.
Through research, our interview with the client, and multiple visits to the school, we were able to
understand the problem, develop the most efficient solution, and fully explain any possible
Through our research, we found that 80% of the students at FDA reside in the Central Harlem
area. All students are required to wear a uniform to school, and graduation and college
attendance are expected of all students. The students are subject to rigorous academics and a
large workload. Students take performing arts, such as music, dance, and chorus, and a foreign
language, such as Japanese. The scores on the Regents exams are 30-40% higher than the
average in New York City. In contrast, the neighborhood of Central Harlem is one of the most
impoverished in all of New York City. The neighborhood is almost completely minorities, with
a scarce 8% of the population being Caucasian. The median household income is $21,508,
almost half of the national median household income. 36% of the population of Central Harlem
is living under the poverty line, with one-third of the adults did not graduate high school. The
neighborhood is 26% children 17 and under, who often do not have the opportunity to succeed
due to their poor living conditions and lack of support. It is now obvious to the group that
Frederick Douglass Academy is a rare school that is bringing a population of children that have
very few opportunities the ability to succeed and become valuable members of society.
During our client meeting, our team was able to understand the specific problem that Frederick
Douglass Academy was experiencing. Our contact, Mauricio Gonzalez, provided our group with
important information about the current problem. The Fredrick Douglass Academy is trying to
encourage their students to become more interested in the sciences and would like to start several
research programs at their school utilizing the natural boundaries of the school. One biologically
important area around the school is the Harlem River, which is currently not in use. The classes
would like to be able to observe the river and be able to measure and record various changes.
However, there is no pathway to the river, which makes it dangerous for students to walk on
uneven ground through brush and rocks to reach the river. Another safety hazard for walking
over to the river is that the students must pass under FDR Drive, which has the potential to have
debris fly and injure students. Also, even if the students were able to get to the river, there is no
area that would allow the students to safely access the river or perform experiments.
Our goal is to develop a solution that will enable teachers and students to safely travel to the
Harlem River and to easily access the river for experiments and observation. We believe that
significant process in relation to the position and function of the jetty have been addressed during
our design timeframe, especially in regard to the legal issues, safety issues, and cost issues that
limit the scope of the project. Our purpose for this project is to fully allow students appreciate
and immerse themselves in the sciences that they have been exposed to in literature and develop
a love so as to pursue careers in those sciences. We believe that our final designs have
developed a bridge between the gap of high school and college level science as to make the
transition easier for the students.
Our product title is “Jetty for Frederick Douglas Academy.” The purpose of the jetty is to
integrate the Harlem River into the academic experience of the students. The jetty will allow
easy access to the river. It will give the students a platform area to conduct experiments, and will
allow 15-20 students to perform experiments together. The platform should account for
approximately one square foot of space per person, excluding the space that will be reserved for
tables and equipment storage. Hopefully these new features will enrich the education in the
sciences of the students. The project is a onetime project that we are the only group researching
and developing a solution for. There is no competition for this product as of now. The only
group currently in the market is the Frederick Douglas Academy, but if other schools near the
water decide they want a similar product, the design could most likely be used. The demand for
this product might not be very high, since the product only targets organizations located near a
body of water.
FDA needs this project because they do not have an easy way to access the river to conduct
scientific experiments. This product may also be used for many tasks by various organizations;
however, for each one some alterations would have to be made, since this product will be
designed specifically for FDA. This product is closely related to other jetties; however, it will
not be exactly like any other one. It will be specifically designed for our client for his needs;
however, it is being built upon other ideas from other jetties and similar devices. Currently the
exact price to develop this product is unknown. However, we know it must be substantially less
that the maximum $60,000 in grants that are possible for our budget. We want to make this
product as cost efficient as possible to meet the needs of our client.
There are several functional necessities for the project. The project must provide the teachers
and students access to the Harlem River. There is also a need for systems such as heating,
cooling, cooling, electricity and running water to be in place on the jetty. There must be enough
space to allow for easy, free movement on the pier for the students. Internet access is another
must, with a wireless system being the ideal solution. The jetty may be used as a storage area for
some of the equipment, but it is not a necessity as much as it is preferred. We hope that we can
organize the construction of the jetty in a timely manner so that it may be finished early summer
2008 as to allow teachers to become familiar with it over the summer. That way the jetty can be
fully functioning fall 2008 for the students to begin use. The schedule could be pushed back if
additional research or money is needed, but ideally the jetty would be useable in a year.
There are several physical requirements that the jetty must have in place. There must be a roof
to protect the walkway and the jetty from precipitation and to allow students access to the jetty in
nearly all conditions. A fence around the pathway and the jetty is needed for safety and security.
Physically, the jetty must not only be large enough, but structurally be about to hold 20 to 30
people at a time. The walkway and the jetty must be accessible to the handicapped. Another
important thing to consider is the assembly of the jetty. Due to tight budget restraints, our client
plans on doing much of the assembly himself. We must make sure the design is easy to follow
and simple enough that it can be done by a few people without heavy machinery. The jetty must
also be made from durable materials that will be able to withstand natural occurrences and last
for a prolonged period of time, preferably over 10 years without any major repairs. The jetty
must be able to withstand temperatures as warm as 105 degrees Fahrenheit (41 degrees Celsius)
and as cold as -5 degrees Fahrenheit (-20 degrees Celsius). It must also be able to withstand
elements such as wind, rain, sleet, and snow.
The jetty must be safe for all users. The distance from the school must be reasonable so it can be
traveled in approximately 5 minutes or less. The path must be comfortable so that no students
have significant issues in reaching the jetty. The students and teachers must have access to all
equipment necessary so multiple trips are not required, wasting valuable educational time. The
jetty design should allow for easy movement. The pathway should permit easy transfer of
equipment. The area must be comfortable for students and faculty. The main task of the jetty is
to satisfy the needs of students and faculty, so aesthetic factors are not very important in this
case. However, it must look neat and clean since it is in an area that is in close proximity to the
school and can be easily viewed by others.
From our understanding of the problem, we have compiled a list of requirements our customer
has for the project. By analyzing these requirements, we were able to identify key functions and
engineering aspect that must be addressed throughout the design stage. One function
requirement pertains to the room. Due to requirement including number of students, equipment
storage, and access, we have concluded that there should be one meter squared space per student,
as well as additional room for tables, sinks, and other equipment. Due to this, we decided that
the room must be at least 20 meters squared in size, and preferably more if it is at all possible.
Another specification pertains to the walkway and stairs. Due to legal restrictions on the land,
we have determined that the pathway and stairs will most likely need to be non-permanent
structures. This affects the materials we choose to use and how exactly we set up the different
structures. There are many other important functional requirements that we have addressed, and
the complete list can be found in the Appendix.
The construction must not harm any animal habitats or cause any major environmental issues
such as pollution. The probes in the water must not conflict with any federal regulations of the
Harlem River. Building under FDR highway must be cleared by the entity who owns the land.
As defined in our problem statement, the design constraints for building a jetty that would
connect Frederick Douglass Academy to the Harlem River include legal issues, safety issues, and
Alternative solutions to our problem must be generated unless legal permission by the state and
federal government is granted to FDA that would fulfill our two functional objectives: (1)
students to maintain and monitor probes from a jetty in the Harlem River and (2) administrators
and constructors to build a jetty walkway, inevitably under the FDR Highway. Before this
project can initiate, some sort of legal verification must be established in regard to these two
Safety, an important value in all schools, is a constraint that shall be maintained in building an
enclosed walkway, with fencing on both sides and a polyester roof along the top. This is to
ensure that (1) only students are using the jetty as an access point to the river, (2) students will be
shielded from debris dropping from the FDR Highway and unpleasant forms of precipitation, and
(3) students’ movement to and from the jetty will be facilitated using the walkway, as opposed to
uneven, rocky areas that surround the river.
Finally, our budget, which consists of a few grants that total approximately $60,000, will be an
obvious constraint, according to our client. The materials that we purchase, which will include
concrete, wood, polyester, screws, tools, rope, and cables for the ramp, walkway, and jetty, will
be carefully projected and monitored before and during the course of the project, respectively.
In our budget, we have calculated that we believe $47,564.40 is the max amount this project
should cost. We tried to overestimate the total cost so that the client would not have to end up
spending more than he budgets for the project, which was an issue in the past. This maximum
amount is well below our estimated maximum in grants, making cost wise the project very
The goal of this project was to provide an access point at the Harlem River for students attending
Frederick Douglass Academy. The initial design included a staircase leading either from the
midpoint or northern most point of the east parking lot to ground level. A walkway was to be
built from the ground to the Harlem River, directly to the east. Several changes had to be made
as a result of two visits to FDA and discussions with our client, Mauricio Gonzalez, and the
principal of the school, Dr. Hodge. For the initial walkway, FDA owns the airspace in that area;
however, a subway track on land owned by the MTA exists directly underneath the school
making it difficult to build there.
On the second visit to FDA, our group encountered an access point to the Harlem River away
from the subway tracks and fences that would block the walkway. In fact, a road had already
been built leading from the ground near the northeastern corner of the school towards the access
point. Most importantly, this road is covered by FDR Drive, effectively shielding the students
from harsh weather.
The final design, therefore, will begin at the northeastern corner of the eastern parking lot of
FDA. A staircase will be built in between the parking lot and FDR Drive, leading to ground
level, just to the left of the wall that separates public property from MTA property. The
walkway, which pre-exists, is a road that extends north towards the access point in the Harlem
River. The general location of the design can be seen in red below:
Figure 1: General marked pathway of Jetty access system
The staircase that allows access to ground level is the first part of the design. FDA is elevated
above ground by approximately 6.7 meters on the northern end, and 9 meters on the eastern end,
the latter being the end we are concerned with. The staircase should be 6 meters in total width,
where 4 is the distance between the parking lot and FDR drive. This accounts for a 56 degree
angle from the ground leading upwards. Figure 2 displays the dimensions of the staircase. Figure
3 and 4 are the models of the staircase, extending from the parking lot to the ground.
Figure 2: Dimensions of staircase
Figure 3: Staircase to ground level Figure 4: Top view of Staircase
The walkway extends underneath FDR Drive for a total of 60 meters. Four slate squares are
placed together in a square a foot apart, leading all the way from the base of the staircase to the
doorway of the jetty storage house. This accounts for the design specification that deals with
safely providing a pathway from the school to the river. FDR Drive blocks any adverse weather
from accumulating on the ground, while the slate squares provide for a smooth transition from
the stairs to the jetty. Figure 5 depicts the dimensions of the walkway, while Figure 6 shows a
model leading towards the river.
Figure 5: Dimensions of walkway leading to the river
Figure 6: Walkway alongside the road
The design specifications require that the jetty be built with access to the river and enough
adequate space for storage and examination of data and materials obtained from the river.
Therefore, the storage room, with an outlet space where the probes will exist. The jetty storage
room will be a 4 meter by 7 meter base, accounting for the design specification of one square
meter per student, plus materials that could be stored inside of the jetty, such as computers,
tables, and sinks. The height of the walls of the jetty will be 3 meters, and the height from the
floor to the tip of the ceiling will be 4 meters. Figure 7 and 8 show models of the inside of the
jetty storage room.
Figure 7: Overhead view, inside of jetty Figure 8: Inside the jetty
This final design of the three-part system – staircase, walkway, and jetty – clearly achieves the
primary objective from our client, which was to create a clear, safe, and efficient link between
Frederick Douglass Academy and the Harlem River. Our design avoids harsh weather, promotes
safe travel through the use of a steady staircase and slate stones along a pathway, and creates a
structure where data can be analyzed using probes directly inside of the river.
As discussed in our problem statement, the purpose of the project is to encourage students from
Fredrick Douglass Academy to pursue careers in the sciences and to allow students to use the
environment around the school in a productive manner. There are many other ways to utilize the
environment while encouraging students to embrace the sciences other than building a jetty.
One way to bring the science curriculum and the environment around the school together is to
create an in school weather monitoring system. This system could take measures of physical
parameters in the air, such as pollution levels, pressure, temperature, and elemental breakdown.
The classes can also test rainwater or monitor animals in the vicinity of the school. This also
allows the school to use the environment but does not have the same legal constraints in using
property not belonging to the school.
The school can also develop an internship program that allows students to get hands on work
with scientists who are in the fields they would like them to pursue. By finding research
laboratories around New York City that understand the social benefit to increasing participation
in the sciences, the school could give their students hands on experience as well as resume
boosters at a fraction of the cost. While this does not allow the students to use the environment
around the school, it still helps bridge the gap between high school and college education and
gives the students hands on science experience. This would also allow the students to look into
more fields of study than otherwise because they could be placed almost any type of lab
If a jetty is not possible, another option is to have the students collect water from the river and
bring it back to the school to perform various tests on it in the laboratory. The school could also
invest in field testing kits which would allow the students to test the water on site. Thus the
students would be able to test without having any permanent structures in place.
It building on the land and having students go and access the probes is not an option, the school
could invest in a probe with such capabilities as cell phone checking or built in satellite data
transfer. This way the school could take information from the river and access it up at the
school, so students could do research and take reading from the river without actually having to
go down to it.
If the staircase and path are the biggest issue, there is a path that could be possibly used. It goes
down the side of the tennis courts and leads to a dirt path that is locked off by a gate. If the
school could get a key from whoever owns that dirt road, they could still have a jetty with
equipment and just not have their own staircase. Due to possibly pile-ups of snow when the road
is cleared, the jetty may not be available year round, but it would still offer good scientific data
for the students to work with for a majority of the year.
Transition Plans and User Documentation
Currently, we have designed a walkway and have determined the most effective pathway for the
jetty walkway as well as the materials and costs. We have also designed the space for the actual
jetty and the costs to build it. A future team could decide an effective way to connect the
plumbing and electricity to the jetty. They could also work on the legality of the issue as we were
not able to determine if it is legally feasible to build outside of school property. Since we now
have a proposal and general design for what the jetty will entail, it will be easier for the next
team to contact the owners of the adjacent property to request permission to build this jetty for
Our partner is very enthusiastic about the project. However, he is very busy and sometimes
difficult to get in touch with. I would advice another group continuing to work with him to set a
day of the week that a responsible group member always sends an email to him, as to keep a
regular contact schedule. Having regular contact to make sure the group and the client are on the
same page is essential, and our group struggled to regularly contact the client, resulting in
choppy and confusing contact. I would also advise a team that is continuing to work with the
client to listen to him and ask him for suggestions for certain products. He is very informed and
knows exactly what it is that he wants so listening to his recommendations for products helps to
keep the project on track because he has many catalogues that are very helpful in finding specific
Our design does not warrant a patent. The design is not something that has never been done
before. We are also using materials that have already been created by someone else, therefore no
patent is needed.

Constraints & Standards
Much of the land is not owned by Frederick Douglass academy.
Must get legal permission to build under FDR Drive.
Must be able to construct project without large trucks due to limited access for vehicles.
Must create a way that students can access the probe without risk of falling into river (i.e.
guard rail, etc.)
Cannot build at all on riverside of school because of train tracks owned by MTA.
Most likely a roof will be difficult, and no permanent path will probably be built due to
lack of land ownership.
Must allow access to the Probes
Must be within all safety standards required
Must bring students safely down from school level to ground level (approx. 25-30 ft)
Must bring together the outside environment around the school and the science education
