Preliminary Design Report Part 2 – Technical Information
1.0 EXECUTIVE SUMMARY
The University of Mississippi (UM), Ole Miss, student chapter of Engineers Without
Borders (EWB) is pleased to work on the Hedome School Building project in Togo, Africa,
project number 1. The current school building was significantly damaged beyond repair. It was
determined from the assessment trip that this village was an excellent partner to work with EWB
to rebuild a more sustainable school facility.
The goal of the project is to supply the village of Hedome with construction planning,
building design, and knowledgeable guidance culminating in the construction of a school
building including administration facilities. General, modern engineering knowledge such as
foundation planning, optimal concrete mix proportions, and truss construction will be passed on
to the villagers during the construction process. This building will provide a school to not only
the children of Hedome, but also to children of surrounding villages of varying ages. The scope
of the EWB project includes building design, site work, and construction management.
The community of Hedome is located in the Vogan Region of rural Togo, West Africa. It
is a community of minimal infrastructure and commerce. The non-governmental organization
(NGO) in Togo is Mission Baptiste Indigene de la Grace (BIG) under the council of Kokou
Loko. Rev. Loko lives in Lome, the capital city, and he drives an hour to Hedome Village
weekly. He is well respected in this community and has strong ties with many of the villagers.
Rev. Loko has discussed with the village chief and the president of the Committee of
Development (CVD) the terms of agreement concerning responsibilities and expectations as
detailed in the attached Memorandum of Understanding.
The program was successfully initiated in 2012 with EWB’s approval to conduct the first
assessment trip in August 2012. The anticipation of the chapter was to secure a water treatment
project; however, the assessment trip revealed a greater need and opportunity for a structurally
sound school. The chapter assembled a diverse team of students, faculty, and professional
mentors qualified to complete the design and build process for this project. The assessment team
via interviews with numerous CVD’s identified potential infrastructure improvement projects as
part of the five to ten year program. The chapter’s efforts are currently focused on the first year
project, Hedome School. Although, the Ole Miss EWB chapter has made only one trip,
individual members have travelled to this region for purpose of relationship building.
The team will design and build one facility, which includes four classrooms, a library,
and three offices on a single foundation. This structure will consist of an elevated slab, exterior
concrete footings, concrete masonry units (CMU) walls, and wood truss roofing system with
corrugated metal. The building will not include HVAC, plumbing, or electrical systems;
however by incorporating CMU breeze blocks, the design is expected to provide sufficient
natural lighting and ventilation.

EWB-USA, Ole Miss
School Building
Calculations carried out for the project consist of design of structural elements,
quantity/cost estimate of building materials, and mobilization costs. Space allocation for
classroom sizes is in accordance with Togolese government school standards. See Section 4.2
for calculations of the structural design.
The chapter prepared detailed engineering and architectural drawings to depict the project
using AutoCAD 2007 software. Engineering drawings consist of trusses, roof views, footing,
system connections, and minor details. Architectural based drawings include elevation views
and a plan view. Detailed drawings of design are included in Section 4.3, along with all other
necessary structural specifications.
It is expected that before the arrival of the EWB-USA, Ole Miss student chapter project
team that the existing school structure will be demolished and proper preparation of the
foundation and concrete forms for the columns and beams of the new school will be completed.
Once the rebar is placed, Kokou will send pictures to Mr. Costelli for his approval. This is the
only way for the team to see the rebar and approve it. Once the project team arrives, shopping
for materials will be the first line of action. If all goes as planned, we will then begin to position
concrete forms for the cast-in-place columns and beams and pour the concrete. While the
columns dry, we will begin laying blocks for the walls. As one team lays blocks, another team
will be cutting wood and building the trusses. After the blocks have been laid and the concrete
columns and beams have sufficiently dried, trusses will begin to go up. Once all of the trusses
have been placed we will then lay corrugated metal over them to construct the roof. Finally, we
will paint the building and begin to clean the construction site. All activities will be supervised
by the EWB project team members and other professionals. Only members of the village will be
doing the actual construction of the building.
By emphasizing simplicity in the structural design, maintenance costs are drastically
reduced. Although the comfort of students and faculty of the school may be increased by
including HVAC, plumbing, and electricity systems, the school is more maintainable in the long
term, which is more important. Also, when constructing the building, the design team has
ensured all products used are readily available to the people of Hedome Village. By including
the villagers in the construction process, they will be capable of maintaining the school. Nails,
wood, and paint are the only materials needed to sustain the building.
2.0 INTRODUCTION
The end goal of the Ole Miss student chapter’s project is to design and build a school in the
Hedome village of Togo, West Africa. The purpose of the preliminary design is to ensure that
the chapters’ design for the school meets the standards of EWB-USA. This includes but is not
limited to structure, funding, feasibility, impact to the community, sustainability and efficiency
among others. The Ole Miss student chapter wants to bring an element of engineering to the
village not previously utilized. With this element of engineering, an appropriate factor of safety
is ensured which is a top priority for a school building. Background information has also been

EWB-USA, Ole Miss
School Building
included in the report which illustrates the process of choosing the project location and the
relationship that has been built over the past few years with the village of Hedome.
3.0 PROGRAM BACKGROUND
The relationship between EWB-USA, Ole Miss student chapter and the Vogan Prefect of
Togo has been building for many years. Medical mission teams from Mississippi have been
going to the Vogan Prefect of Togo since 2004 through a relationship between pastors Gary
Richardson of Oxford, Mississippi and Kokou Loko of Togo. The two friends went to graduate
school together in New Orleans, Louisiana. In 2008, Kokou Loko visited Oxford and Ole Miss
Engineering to deepen the relationship between his non-profit organization, Mission B.I.G.
(Baptiste Indigène de la Grace) and those in Mississippi willing to help. As a result, Marni
Kendricks, Assistant Dean of the School of Engineering, joined one of the medical missions to
Togo in 2008 with the purpose of assessing the needs and means for building a future hospital.
The EWB-USA, Ole Miss chapter was formed in 2009 and after considering several potential
projects around the world, the chapter, together with an external advisory board, decided that the
best chance of project success would be with a community in Togo, where EWB-USA, Ole Miss
chapter members already had a relationship with Rev. Kokou Loko. The chapter’s application
for a new project was approved by EWB-USA in December 2011, and the chapter has now
performed its first assessment trip during August 2012.
The purpose of this trip was to conduct multiple interviews to assess the area’s needs and
to choose a village that could match our chapter’s requirements and abilities. During the
assessment trip, communication with villagers about their needs was necessary before a specific
engineering design could be mutually decided upon. Through Rev. Loko, the chapter was made
aware that the priority needs varied from clean water and irrigation for agriculture to medical
clinics, schools, and roads. After several interviews with leaders of different villages, the EWB-
USA, Ole Miss chapter representatives identified a manageable school project opportunity in
Hedome Village. Hedome residents had recently shown industriousness by building a road
within the village. Also, they had built a school for more than 300 of their children. Due to poor
construction, a storm caused some of the walls to collapse. The EWB-USA, Ole Miss chapter
felt that we would be able to assist in the reconstruction efforts of the school building.
Therefore, the project will be focused on the design and construction of a school house, as
detailed later in this report. Furthermore, the chapter is committed to continued assessment of
the community’s needs as well as providing engineering design and operation and maintenance
plans for this project and future projects over the next 5 to 10 years.

4.0 FACILITY DESIGN
4.1 Description of the Facilities
The school building will consist of four classrooms, three offices, a library, and a
common area between the offices and library. The classrooms will be arranged side by side in a
row with each classroom having two exterior doors. The offices and library will be located at the
end of the row of classrooms each having one exterior door. Each classroom will be 9 meters
long and 7 meters wide. Each office will be of a differing size. The roof will overhang along the
distance of the classrooms to make a covered walkway which is 1.5 meters wide and 36.6 meters
long. The overhang as well as the walkway will run along the length of the classrooms and stop
when reaching the office area. The overall structure will be 47 meters long and 10.3 meters
wide. Open blocks will be used in the majority of the walls to act as a breezeway to allow air
flow and light into the classrooms due to lack of available electricity in the village. Trusses will
not have any decking, making them visible from inside the building. Steps will be located
outside each classroom door and the doors to the offices. The proposed layout that has been
described was given to our group specifically from the Hedome village, so this was decided to be
the architectural design. See the architectural rendering and floor plan in Appendix B.
4.2 Description of Design and Design Calculations
The design team worked diligently with Michael Costelli while performing calculations
and checks for the school building. Due to the lower standards in construction materials in Togo,
the team used very conservative numbers when performing all calculations. The first step was to
determine the loads. It was assumed that 20-gage galvanized corrugated steel would be used as
the roofing material. From this assumption and the AISC Steel Manual, Edition 1 (AISC 1927),
the weight of the roofing material was able to be determined. The dead load was calculated to be
5 pounds per square foot (psf) due to 1.5 psf coming from the corrugated steel and 3.5 psf being
extras acting as a safety factor. The live load used was 20 psf according to the Mississippi Gulf
Coast Standards due to similar environmental loads.
To determine the decking spans, the moment and bending stresses were calculated. After
trial and error, the decision was made to have 2 inch (in.) x 4 in. lumber at 18 in. spacing. Other
spacing would have worked out mathematically; however, this option was chosen because it
would result in one 2 in. x 4 in. at every joint of the truss and another 2 in. x 4 in. directly in the
center making it easier during the construction phase and still passing the checks of the
calculations. The calculated deflection fell in the accepted values range which made the team
confident in this choice.
The truss spacing was assumed to be 4 feet (ft.). Using the assumptions for the section
modulus from the AISC Steel Manual (AISC 1927) and completing calculations for the moment
and bending stress, we found this spacing to be an acceptable number. The loads on the trusses

EWB-USA, Ole Miss
School Building
include: dead load of 5 psf, live load of 20 psf, and wind load of 26 psf. There were two
different trusses that needed to be calculated in order to have a continuous exterior roof line per
request. The first truss that was considered spanned 24 ft. while the second spanned 34 ft. The
group based their design off of a Triangular Howe 8 Panels at Top & Bottom from Simplified
Truss Design (Melaragno, M. 1981). Dead plus live load and dead plus wind load conditions for
each of the trusses were calculated as well as a cantilever case for the overhang of the roof on the
24 ft. truss. The members with the highest compression load in the 2 in. x 4 in. and 2 in. x 6 in.
as well as the highest tension load in the 2 in. x 6 in. were checked for validity. For the
compression members, the slenderness factor was calculated in order to find the allowable stress
of the wood. All members were less than the capacity which confirmed that the calculations
were correct.
The columns and beams were calculated using design software, Digital Canal
Corporation Concrete Column Design and Concrete Beam Design (Digital Canal 2013). All
calculations were compiled into a document and can be found in Appendix B with the rest of the
calculations. From this software it was concluded that the beams should be 8 in. x 12 in. with 4
#5 rebar for support and #4 rebar @ 18 in. for the stirrups. The columns are to have 2 #4 rebar at
the top and bottom of the beam for bending reinforcement and #4 bent rebar @ 18 in. on center
for shear reinforcement. The columns will be formed using concrete blocks as opposed to
plywood forms due to lack of resources in the area.
The analysis of load bearing walls was performed for the fully enclosed ends of the
building. The height of all walls will be ten ft. and made out of 8 in. x 16 in. block. The velocity
of the wind was assumed to be 130 miles per hour (mph) using values similar to that of the
Mississippi Gulf Coast which resulted in a wind load of 37 psf. After finding the combined
stress on the wall, it was determined that vertical reinforcement of #4 rebar @ 32 in. on center is
required.
The foundation was calculated considering an allowable soil pressure of 1,000 psf. It was
assumed that it would be 2 ft. x 1 ft. with a total load of 1,300 pounds per feet (lb/ft). These
assumptions proved to be correct and it was concluded that there would need to be a minimum of
#4 bars @ 24 in. for the bottom reinforcement.
All analysis, assumptions, and calculations are shown in detail in Appendix B. Also see
Appendix E for a list of all citied sources from which the assumptions were made.

5.0 PROJECT OWNERSHIP
The Hedome School Building project ownership belongs to the community of Hedome
Village, the village chief, and the CVD in partnership with The University of Mississippi student
chapter of Engineers Without Borders and the NGO in Togo, Mission BIG.

EWB-USA, Ole Miss
School Building
6.0 CONSTRUCTABILITY
The EWB-USA, Ole Miss chapter will play the role of construction supervision. As the
work is being done the group will oversee the safety aspect of construction as well ensuring
accurate and timely work. All of the materials will be produced on site or purchased from the
village or a nearby village to reduce cost. The columns and beams will be formed using concrete
blocks versus plywood to avoid excess cost and time. The group will split up into teams
according to their strengths and oversee the local workers to ensure the accuracy of construction.
Since there is no electricity, we will not be using any heavy machinery or modern construction
tools apart from bringing personal tools from the United States, such as a power drill.
According to the Executive Summary, the foundation and concrete forms for the columns
and beams of the new school will be completed. The foundation preparation and completion will
include: digging of the footings by hand by Hedome village volunteers, placement of the rebar
and pouring of the concrete. Throughout each construction step listed above, photographs for
quality control will be taken by Rev. Kokou Loko and sent to Mr. Michael Costelli for approval
and to obtain a go-ahead for the next construction step. The drying of the concrete foundation
will require a 21-day setting period. Preassembly of building the structure will require Hedome
village volunteers to also make a total of 1,100 form blocks for the cast-in-place columns and
beams. Also, an A-frame for a pulley system will be constructed prior to the EWB-USA, Ole
Miss chapter team arrival.
Once the project team arrives, shopping for materials and tools will be the first line of
action estimating a length of 1 to 2 days. Beforehand, Rev. Kokou Loko will have set in place
multiple teams of skilled workers available from Hedome and nearby villages. If all goes as
planned, we will then begin to position concrete forms for the cast-in-place columns and pour the
concrete. It is estimated to take 6 days, working 10 hours per day, to build 40 columns with 15
masons. While columns are drying throughout the 6 day period, we will begin laying blocks for
the walls. As the column/wall team lays blocks, the truss team will be cutting wood and building
the trusses. This will take an estimated 3 days with 5 workers. After the blocks are layed for the
walls, the beam team will position forms above the highest row of breeze way blocks and cast-
in-place the concrete beams. After the blocks have been laid and the concrete columns and
beams have sufficiently dried, trusses will then be assembled above the beams. Once all of the
trusses have been placed we will then lay corrugated metal over them to construct the roof. Each
team will be supervised by the EWB-USA, Ole Miss project team members and other
professionals present.
7.0 OPERATION AND MAINTENANCE
The CVD is a group of 10 elected village members who function as a body to operate and
maintain Hedome building structures. Operation and maintenance upkeep for the Hedome

EWB-USA, Ole Miss
School Building
School Building project will consist of housekeeping and structural preservation. A structural
task will be to maintain the perimeter of the foundation in efforts to control soil erosion from rain
by way of metal roof gutters being cleaned frequently. Other structural tasks will be to repair
roof leaks and add caulking around metal roof screws to preserve roof system from rust.
8.0 SUSTAINABILITY
No electricity will be used in the actual Hedome School construction process and daily
use by local teachers and students. Yet, in the material preparation of the structural concrete and
wood before purchase and mobilization, electricity will be needed. Mobilization of the structural
materials will minimally lessen the availability of fuel. Not to mention, a minimal depletion of
the natural resource, timber, will occur. Because all materials are being purchased in Lome,
Togo, the Hedome School Building project will contribute to home economic growth. Not only
will the use of the Hedome School Building provide for a safe place of learning and directly
improve quality of life, the construction process will be used as a learning tool for the Hedome
village partners involved. This will create a conduit of knowledge for Hedome village
individuals that can be shared with other nearby communities. Hopefully this sharing of
knowledge could be developed into a profitable trade of labor.
9.0 MONITORING
9.1 Monitoring plan for current project
Three metrics the EWB-USA, Ole Miss chapter are using to measure the success of the
Hedome School Building project include: safety, quality, and resources. A safety measure
attributed to the design of the school building is the choice of not designing and constructing a
concrete roof due to inconsistency in concrete mix and lack of knowledge of the concrete
strength. The Hedome School Building design meets requirements set forth by the Togolese
government school building standards regarding the size of classroom per number of students.
Thus, the quality measure of the building design with regards to the area of each classroom is
quantifiable and will meet its target because the actual construction of the school building must
be built according to the chapter’s engineering design. Resources used for the school building
project must be purchased in Togo, therefore monitoring this metric can be done by keeping a
record of receipts of all materials and supplies purchased.

11.0 PROFESSIONAL MENTOR/TECHNICAL LEAD ASSESSMENT
11.1 Professional Mentor/Technical Lead Name
Michael R. Costelli, P.E.
11.2 Professional Mentor/Technical Lead Assessment
The EWB-USA, Ole Miss chapter design team (Team) narrowed the field of materials of
construction and set about developing a detailed approach to the new school. A floor plan and
elevations were received from a local Architect related to the village chief. The plan revealed a
similar arrangement to what was considered earlier by the Team.
On November 2, 2012, I met with the Team in Oxford, MS to discuss the design and its
accomplishment. Roof and wall materials, wood trusses, metal roof decking and phase of the
work were subjects of discussion. A project scope cost of $35,000.00 was considered.
On January 30, 2013, a telecom with the Team was held. Input from a Seabee from
NCBC, Gulfport was discussed in detail. The Alternative Needs Analysis sections were
considered. Phased construction and a method of instructing the local citizenry help were
recognized by the Team as topics of importance in this project. A list of materials needed for
construction was begun. The need for an estimate of the cost of the Project became apparent and
efforts were begun to learn of the material costs in Togo. On March 27, 2013, the Team received
a list of local prices from Kokou.
On March 28, 2013, a telecom with Ms. Tiffany Martindale/EWB Project Manager was
conducted in which Professional Mentor Michael Costelli was introduced. Ms. Martindale
inquired about the Team’s work, housekeeping items and the next step to the 524 Report.
Details of construction were discussed since Ms Martindale, a structural Engineer, was familiar
with the need for concrete and grout mix designs, use of 40 ksi reinforcing steel bars and other
such items.
On March 30, 2013 I spent time at length with my daughter, Maddie Costelli, providing
design assistance for the individual building elements such as foundation, walls, roof framing
and decking. I furnish basic design aids that I have used through the years of my private practice
of structural engineering. Roof truss design was left for a later meeting in Oxford on April 6,
2013 at which time I presented 2 methods of analyses for simple trusses. Each method was used

to check the other and a final design was done on the following day using wood design formulas.
The balance of the meeting was used to assign responsibilities for CAD drawings of the building.
I believe the Team understands the scope of the project and is willing to undertake the
task of construction of the school. The technical qualifications of each student at this level of
education will be greatly enhanced by a project of this type.
11.3 Professional Mentor/Technical Lead Affirmation
I, Michael Costelli, acknowledge my involvement during the preliminary design and my
acceptance of responsibility for the course that the project is taking.
