PROJECT DEFINITION  • The need that the CSL project addresses  The obstacle that the UBC Farm has requested us to address is a lack of convenient and user-friendly transportation options for bringing a greater volume of produce to campus, in addition to other public events. The UBC Farm owns a 1984 Toyota Corolla hatchback, which is currently their only means of transporting tables, signs, totes of produce and other equipment needed to set up a market stall. This is often a cumbersome and labour intensive affair, an issue that this project will address  • Stakeholders  Susan Nesbit ( Professor of UBC Civil Engineering Department)  Instructor of CIVL 201/202 classes  Amy Frye, Andrew Rushmere, Tim Carter (UBC Farm staff)  Main contact people for trailer design and building considerations  Brenda Sawada (Sustainability Office SEEDS staff)  Coordinator of the project (in charge of organizing stakeholders meetings, report publishing, resource sourcing, and making sure everyone stays on task)  Lee Ferrari (Fleet Manager, Plant Operation Staff)  Brings expertise, and possibly resources in dealing with trailer sourcing, maintenance, cleaning, and repair  Tracey Mason (UBC Community Learning Initiative Staff)  Helps facilitate links between UBC classes and community partners such as the UBC Farm  UBC Farm Mobile Market Trailer Project                                                                                                                 CIVIL 201 Community Service Learning  8   • Final output of the project  The main objective of this project is to design and build a Mobile Market Trailer that can be towed behind the UBC Farm car and used to bring produce to campus for sale. This market trailer will be the final output of this project  • Project constraints  Budget in a range of $500 to $1000  Timeline  The dimension of the trailer  Limited free materials from UBC Farm  Possible limited expertise in certain tools  Working environment  The weather might not be suitable since the construction time will be in February (rain, cold temperatures, possibly snow)  The need to consider sustainable materials  Maintenance and repair  • Project assumptions  Initial project budget is $500  Budget is adequate for the project  Enough help, tools and materials are available from UBC Farm  We can get help from experts, friends and other people  Materials we have to buy do not exceed the budget UBC Farm Mobile Market Trailer Project                                                                                                                 CIVIL 201 Community Service Learning  9   Days and hours to access to the project site are adequate (UBC Farm)  Ability to obtain a free trailer before February 2010 from Lee Ferrari  In the event we do not get a free trailer from Lee, that we can get a free trailer from somewhere else instead, i.e. craiglist.com and freecycle.org  The base of the trailer size is 8 by 5 feet  IV. SCOPE OF THE PROJECT   Project Justification UBC Farm is currently in need of a market trailer in which they can store fruit and vegetables when taking produce to the market and other places to be sold. They have requested that we build a trailer that can be towed by a UBC Farm vehicle. The purpose of this project is to build a mobile market trailer to suit their organizational needs.   Project Outcome The expected outcome of this project is that we as a group will coordinate our efforts and build a trailer with the resources (money and materials) and time available to us. We also expect to learn how to work with tools and equipment and materials that we will be using in the construction of a mobile market trailer. Eventually we will turn this trailer over to UBC Farm for use when they transport their produce to the market. We expect to come away from this project with experience on how an engineering project is managed and completed.    UBC Farm Mobile Market Trailer Project                                                                                                                 CIVIL 201 Community Service Learning  10    Project Deliverables The project deliverables will include a finished market trailer that is fully capable of storing fruit and other produce from UBC Farm. The trailer should be sturdy enough to withstand the rigour of travel on the road back and forth between the market and UBC Farm, since there may be a considerable distance between the two locations. Also, the trailer must be built strong enough to endure the elements as well as shocks caused from bumps in the road. This trailer will be handed over to UBC Farm by the end of the project timeline. Other deliverables include a Community Service Learning Design and Planning Report on our design ideas on how the trailer should be built, as well as detailing what tasks are allocated to which members. This report will also list materials and other equipment that we will need in order to complete this project, and will be submitted to the instructor of Civil 201 for approval by 4pm, December 4th.   Project Objective The objectives of this project from the group members’ perspective are to learn how to work together in a team, get an idea of what it is like to build a market trailer, learn how to successfully communicate with an organization in a professional manner, as well as properly demonstrate the process of proper engineering design and planning – which will be shown in this report. From UBC Farm’s perspective, the objectives of this project are to increase UBC Farm market revenues by increasing the amount of produce that the client can take to off-campus sales, in addition to decreasing the time needed for UBC Farm staff to pack, set up and take down market stands. Another objective is also to reduce the number of staff needed to take produce to a market sale, since the market trailer will only require one person to detach from the vehicle, unpack, and set up the produce for sale. The reverse process – which will involve putting away remaining produce, packing, and attaching the trailer to the vehicle – will also require only one person.

Recommended Design:   We decided to choose a fixed roof because it is easier for the team to implement and build due to our limited skill. Moreover, the cost for the fixed roof is lower than the adjustable roof and it does not require any form of setting up   Although UBC Farm suggests that the trailer be able to carry 16 totes for the sale purpose, we have decided to design the trailer to carry 8-10 totes instead. This is because that the design option for 16 totes requires a two-level storage area given the dimensions of our trailer, making this design an unsuitable option. Also, the height of the trailer would increase as a result, leading to possible instability. As a result, we decided to implement the 8-10 totes design since the storage area is easier to build and cost less according to our budget.   Having a separate tent and table for the check-out area allows the staff working with the trailer to have more space during sale. It would also require less money to implement and build this design option. In addition, the folding table would be more difficult to build, thus making it less desirable.

DETAILED DESIGN  A. Design Description   Our trailer design is based on a sketch provided by UBC farm.  The design is to be built on an existing trailer that will be provided in January 2010* (See Figure 2&3). Due to current monetary and construction constraints, our trailer is a wood based design.  It features a wooden inner frame with plywood cover.  Recycled materials will be used where applicable.  While our design is wood based, our conceptual design could be adapted to a metal design if additional resources become available next semester.   One of the design requirements was for the trailer to have a functional display space for market produce.  Our design features two display areas, one on either side of the trailer.  This dual sided design provides more display space and allows for more display options.   Our design also features multi-level display trays.  The lower tray provides ample space for larger produce, while the upper tray can be used for smaller sized produce.  Both trays are angled to allow for easier viewing of the produce and provide a more attractive display area.   Another design requirement was that the trailer include built in market signage.  Our design feature large 1.1’x 6.4’ whiteboard signs on either side.  The whiteboard material was chosen to allow for more signage options.  In addition, the large doors covering the tote storage can be painted with additional signage or UBC logos if desired.  UBC Farm Mobile Market Trailer Project                                                                                                                 CIVIL 201 Community Service Learning  30   Due to the fact that our design does not include a cashier area, we have included a storage space to store the following items: 2’x6’ folding table, 10’x10’ folding tent, cash register, scale, and stool.  The items can be used to set up a cashier area which can be placed wherever is most convenient.  This separate cashier area design allows for more flexibility during set-up.  The storage space is accessible from the rear side of the trailer and covered by a door.  The storage space is large enough to store additional materials, such as additional tables or extra totes, if needed.   To protect the produce from the elements, our design features a roof which extends to the edges of the display trays.  The roof is to be constructed of either corrugated metal or corrugated plastic depending on the availability of used materials.  The pros and cons of the two types of roof are discussed in the following section.   One of the design goals was the ability to hold 16 large (1.3’x1.3’x1.8’) Rubbermaid totes and have them easily accessible.  Due to space constraints, our trailer is designed to store 8-10 totes, depending on the size of the trailer provided by UBC Plant Ops. Additional totes can be transported in truck which will be used to pull the trailer.  Storage of the totes in the market trailer is accomplished by placing the totes beneath the display racks.  The totes are accessible from the outside of the trailer by lowering the cover doors.  The cover doors hinge from the bottom to allow for easier removal of the totes as the doors.  The use of one large door for each side allows for faster and easier removal of the totes during set-up.  Also, if UBC Farm chooses to have locks on the doors, only two locks will need to be removed during set-up.  *Note - Due to the fact that the trailer has not yet been provided, the dimensions listed in the following section are estimates only and based on the trailer that we have requested from UBC Plant Ops.

PROCUREMNT PLANNING: MATERIALS, TOOLS, COST ESTIMATION (PURCHASE AND RENTAL) All cost for materials and tools are based on the assumption that the team is not provided with pre-used tools and materials, thus making the total cost calculation only an estimating cost. The information on the product name and cost estimation is obtained from the following sources: • Canadian Tire, http://www.canadiantire.ca/home.jsp • Rona – Canadian Branch, http://www.rona.ca/content/home • United Rentals- Canadian Branch, http://www.ur.com/ There are also sources such as Vancouver Craigslist and Yahoo Free-Cycle where recycled materials and tools are available. However, their quantity is limited and not guaranteed to be available during our schedule days of construction. Therefore, this cost is not included in the following cost calculation. During Term 2, we will research these organizations before the implementation phase for recycled materials in order to make this project a more sustainable and on budget.

As a result, an approximate estimate of the trailer’s weight is demonstrated in the following table:   Components of the Trailer  Weight   Wood (Yellow Pine)  Density = 28 Pound/ Cubic Feet Volume = (35)( 1/6 ft. x 1/3 ft. x 8 ft.) = 16 Cubic Feet Weight = 436 Pound  Corrugated Metal/Plastic Roof   Approximate Weight = 15 Pound   Materials ( Totes + Fruits & Vegetable)   Approximate Weight = 60 Pound  Foundation of the Trailer (Wheels and Trailer Bed)   Approximate Weight = 200 Pound  Total Weight Approximation:                                             711 Pound Table 9: Weight Calculations UBC Farm Mobile Market Trailer Project                                                                                                                 CIVIL 201 Community Service Learning  43  XI. RISK PLANNING  Risks Responses Injuries caused by working with power tools to students and UBC farm members ●   Consult experts and  receive basic knowledge of the tools before operating the tools ●   Have first aid kid on site ●   Have one person with first-aid certificate on side ●   Have access to phone on site ●   Have a car on site while working Miscommunication formed between students and community members ●   Have one person responsible to contact the organization or client ●   Forward all e-mails and important decisions to other team members as quickly as possible Failure to meet the desired time lines ●   Always have back up dates ●   Plan alternative plans ●   Plan a few days before schedule Poor weathers (Snow, Storm, or Rain) ●   Have tarps to cover expensive power tools and other water sensitive materials Lack of communication and coordination between team participants during construction days ●   Appoint a leader to give team members a guide line ●   Set goals before starting the project each day ●   Arrange group meetings during break if problems arise during construction ●   Complete progress evaluation at the end of each day  UBC Farm Mobile Market Trailer Project                                                                                                                 CIVIL 201 Community Service Learning  44  Trailer has the potential to collapse when carrying excessive loads of goods ●   Measure the amount of load that the trailer is capable of carrying, and clearly inform the maximum load to the clients Rusting of metals materials on the trailer may injure workers, as well as weakening the structure of the trailer ●   Provide protective coating for the metal materials on the trailer that are exposed to the atmosphere Add-ons built on trailers will raise the center of gravity, making tipping of the trailer more likely ●   Slowing the car speed down while towing the trailer Lack of materials ●   Consult experts to seek for alternative materials if possible ●   Consider the overrun cost that might be due to wrong calculations and estimates Not all students present on the construction days ●   Get confirmation from most of the team members before arranging a meeting ●   Try to contact those who are not present Table 10: Risk Planning
