ENGR215 Project Page in Progress
This page is a project page in progress by students in Engr215. Please refrain from making edits unless you are a member of the project team, but feel free to make comments using the discussion tab. Check back for the finished version on May 15th, 2014.


The purpose of this project is to replace the current play structure at the Redwood Coast Montessori School (RCMS) and the Manila Community Center, located in Manila, CA. Redwood Coast Montessori is a school with 80 students that range from Kindergarten-Six grade. The children's education is formed around hands on learning rather than traditional classrooms, desks, and whiteboards. The students are allowed to express their own interest in how they want to learn throughout each day. Like regular public schools, they're allowed to go outside and play during their scheduled recess times, but unlike regular public schools, the only play structure that they have is a log. The Gridiron team from HSU Engr 215 class was assigned the task of coming up with a play structure for the school,which ties into their hands on style of learning. A representative from RCM met with the students weekly to work on the design and help to get the projects implemented into the school. The board of directors have to give the final approval for the play structure to be installed.


Through various brainstorming events and discussions, we came up with multiple solutions for the school. After meetings with a representative from the school, and a lot of information regarding possibilities of how they'd like the play structure to be built. We decided on criteria that the play structure would have to fit. This allowed us narrow down what we could really build and after researching all of the aspects regarding a play structure for an elementary school in a dune ecosystem we took everything into account. A delphi matrix allowed us to come up with our top four choices of the play structure. In the end, a vote within our team decided to build a traverse rock climbing wall for the school.

Problem statement and criteria

Specifications and considerations are the defining aspects of the play structure. These aspects have been set forth by the team Gridiron with accordance with the client at Redwood Coast Montessori based on the school's and the community center's needs. The play structure design must meet the criteria, and stay within the constraints listed below in table below.

Criteria Weight Constraint
Safety 9 Wall must have no sharp points or corners, and paint must be child friendly
Cost 8 Must not exceed $400
Maintenance 8 Parts should be easily fixable/replaceable by regular staff
Aesthetics 6 Any art displayed on wall should reflect that of the coastal (manila dune) environment
Age Appropriateness 5 Structure is usable by children from ages 6-12
Concealment 4 Wall should be capable of being hidden by staff to reduce distractions outside of play time
Upcycled Materials 4 Recycled materials will be used whenever possible

Testing Results

Fig 1: Testing results

Team Gridiron put one section of the wall together to conduct a series of tests to see if everything was working properly. Each team member was able to climb up and stand on the holds proving that the wall can withstand a greater amount of weight than the kids. As you can see in Figure 1, the structure can withstand the weight of an adult.

How to build

Building a Traverse Climbing Wall
Caption Step 1 : Cut the pieces of lumber for the frame.
Caption Step 2 : Build the frames for the sheets of plywood.
Caption Step 3 : Primer the sheets of plywood.
Caption Step 4 : Paint the sheets of plywood.
Caption Step 5 : Drill the sheets of plywood onto the frame.
Caption Step 6 : Drill the rock climbing holds onto the sheet of plywood.

Discussion and next steps

The next steps in our process is to finish putting the climbing wall together and leave it prepared to be installed. The board of directors at the Manila Community center denied our proposal to install the climbing wall, and we have to wait until the next board meeting to come with revisions to answer all of the worries regarding the installation process. Until then, we are to leave a detailed instruction manual for the staff at Redwood Coast Montessori to install the climbing wall after the board meeting.
