Re: Community center housing addition for mission family
Wayne Moss,
The construction management students from the University of Minnesota are excited to have the
opportunity to help come up with a plan to provide additional housing on site. It was a pleasure
getting to look around the site and getting to hear a little about what your organization does for
the Bajo Tejares community. By looking at the existing reading room and listening to what needs
you have, the following designs have been submitted. .
Our objective was to provide you with an initial proposal that will help you understand the
possibilities the project has and assist with fundraising efforts.
Thank you for the opportunity to explore the organization and submit a proposal to add living
space. The services your organization provides the people of Bajo Tejares are greatly appreciated
and we are happy to provide a small contribution to help you make that experience even better.
Sincerely,
The University of Minnesota Construction Management Students

Mission Statement
The University of Minnesota Construction Management Students aim to fulfill the needs of our
Costa Rican clients by creating affordable designs that will effectively use the limited space
available. We focus on creating spaces that allow the client to better serve their communities.
Our goal is to create a path to complete the project and make a difference in the community.
6. 5
Project Background
Objective
To design and plan a space that will be used for lodging by visiting missionary families and
groups. The new space will be built on top of the existing reading room building and utilize the
current water and plumbing fixtures from the building below. It will also be built while
maintaining a safe environment for the young children. The proposed design will be thought out
in a way that will cause minimal disruption to the daily activities of the community center.
Client Profile
Faithful Servants Mission operates the community center. Their goal is to provide impoverished
families with a place to send their children after school. The mission helps the children with
reading and math, leads them in recreational activities, and hosts evening bible groups and
Sunday mass. They aim to serve the families of Bajo Tejares because it is one of the poorest
neighborhoods in San Ramon. Currently there is no lodging space on site for visiting mission
groups to live.
Site Parameters
The site is located approximately 2 kilometers from the city of San Ramon, CR. At first glance it
poses a few challenges. Being an enclosed compound, the site area is of primary concern. There
is limited space for new construction and what is available is either currently being developed or
necessary for pedestrian and vehicle traffic in and out od the site. In addition to space issues, it is
important that the community center maintain everyday operations throughout construction.
Another obstacle is overall site topography because of a large elevation change from front to
back, there is even less buildable space. The last major difficulty is site accessibility. The entire
property is enclosed for safety reasons, which could pose a potential issue with moving material
and equipment to and from the construction area.
7. 6
Program
To better understand the needs of the community center we took a look around the area and
talked with Kathleen. The design team also took a look at her current apartment outside of the
site to gather design ideas. With her input and feedback we were able to create design that would
suit their needs.
Multiple bedrooms Currently limited space is available onsite for the visiting
missions. Multiple rooms would give space for a family and/or
other mission groups.
Full kitchen and
laundry area
The space will be designed to be self-sustaining to provide a
comfortable living space for long periods of time.
Bathroom facilities Create 1-2 bathrooms depending on the available space. Ideally
the toilet will be separate from the shower and sink.
8. 7
Iterative Design Process
Before we could initiate the design process we conducted a site visit to gather information and
ideas for our design. As a team, we evaluated the site of the proposed addition as well as the
existing apartment. After visiting the site, the design team ran a design charrette to gain a better
insight of which ideas we should pursue further. During our visit, we were able to get a better
idea of the future and current needs of the Bajo Tejares Community Center. The needs we found
are as follows:
• Long-term living quarters for a single family
• Short-term dormitory space
• Permanent living quarters for the director
• Better use of space
• More bathrooms
• Natural light
The most important factor we emphasized is the need for long-term living quarters suitable for a
single family. We wanted to provide a base option that meets your needs as well as an option that
goes above and beyond your current needs in order to maximize the potential of the property.
During the design process, multiple unit layouts were considered. Ultimately, we agreed on a
layout that we believe to best suit your needs. Once we came up with our design options, we
were able to draw up detailed plans and 3D renderings to help imagine the finished project.

Design Opportunities and Logistics
Workplan
The main concern with this project is Safety. The site is a functioning community center with
high civilian traffic, including children. Our work plan will minimize the risks associated with
the project while delivering of a quality product on schedule and on budget.
Upon your approval, construction will commence November 1st
, the start of the dry season. The
size of the proposed building options allows for it to be completed before the end of the dry
season, which will decrease cost and risk associated with rain.
Overview of Schedule (both options):
1. Mobilize to site (November 1st
)
2. Set up site perimeter to ensure the safety of the public, and that no children will
wander into the site.
3. Remove and stockpile existing roof materials for reuse. This will prep the existing
structure to receive the additional level.
4. Construct columns to support additional level, as the existing structure will not
support the loads.
5. Erect the steel to support the additional level that spans above the existing parking
lot. In the event the owner choses option 1, this task will be shorter.
6. Enclose the additional level by reusing the existing roofing material as well as new
materials.
7. Clean the site and turn over to the community within time allotted in the respective
schedules.
The current proposed schedule utilizes 7 workers onsite. Unfortunately, this project will
temporarily close the current reading room, and the activities that occur within the reading room
will need to be relocated to a different location.
10. 9
Logistics and Options
As shown in the above graphic, the construction site will be enclosed to minimize the risk of
unauthorized entrance to the site. Given that there are constantly children within the community
center keeping a secure site perimeter to ensure the safety of the kids is of the utmost importance.
11. 10
Option 1 (Family living, without carport)
The design of option 1 is to provide a family living space. This option will be a second story
addition to the current reading room/classroom building and will have the same footprint as the
current building. The area of the existing site is approximately 19’ x 39’ (5.8m x 11.9m). This
option will attempt to reuse roofing materials that can be salvaged. The overall goal of this
project is to create a 3 bedroom, 2 bathroom long term living facility that will serve long term
missionaries. Utilizing the existing footprint will create a comfortable living environment that
meets all requirements. The addition will have 69 sq. meters of living space and have features
that include:
• 1-Master suite equipped with shower, toilet, sink and closet space
• 2-Bedrooms with shared bathroom, shower, toilet and double sinks
• Full kitchen including: Refrigerator, sink, countertop, stove top, dishwasher, top and
bottom cabinet space
• Dining room: room for 6 chairs
• Living room: couch, TV and chair
• Storage and cabinet space
• Top and bottom laundry machines
• Stairway to unit with small porch

12. 11
Option 2 (Family living, with carport and dormitory)
The design of option 2 is to provide a family living space and dormitory on the second level of
the reading room/ classroom building. This design includes reinforced columns that will support
the second floor and will create a carport next to the structure. The entire area of this addition
will be approximately 19’ x 59’ (5.8 m x 18 m.). The design provides an exterior stairway to the
upper level that will connect the living space and dorm via an elevated porch. The addition will
have 78 sq. meters of living space (approximately 60%) and 32 sq. meters of dormitory space
(approximately 40%) and have features that include:
• 1 – master bedroom with master bath: shower, toilet and sink
• 2 – Bedrooms with communal bathroom sinks. Separate showers and toilet.
• Full kitchen featuring: refrigerator, stove, sink, dishwasher, top and bottom cabinets.
• Dining room with chairs for 6
• Living room with room for couch and TV
• Top and bottom laundry machines
• Storage and closet space
Dorm room will include:
• 3 bunk beds to sleep 6 people comfortably
• Cabinet and storage units
• Small kitchenette with microwave, mini fridge and sink
• Separated shower, toilet and double sink
Carport will include room for 2 cars and will have additional storage space

Note* All structural designs are schematic only and will require further engineering to ensure
safety and feasibility.
13. 12
Project Recognized Risks
1. Unauthorized entry of civilians or children.
2. Fall Hazards associated with the erection of the second level. Any work above the
existing razor wire must be accompanied with appropriate fall protection.
3. Building to the edge of the property. Any damages to the fence or neighboring
property must be repaired.
4. Unforeseen conditions with regards to the structural integrity of the existing
concrete block and soil conditions.
5. Dust / Noise pollution drifting to the surrounding compound.
6. Sparks / Slag falling from welded connections on second level steel could burn or
start fires
