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.

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

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

Hedome, Togo, Africa

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.

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

Hedome, Togo, Africa

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.
