The first week of class was dedicated to allocating groups and what they needed to do in order to begin the project. We were in charge of researching exactly what was needed to construct the SIPs (Structural Insulated Panels), where we could obtain the necessary materials and to price them accordingly.
When we first began researching the materials we had some trouble locating them with the correct requirements.(sounds funny..maybe u can word that better than i can) We had difficulties getting the pricing and sizing information for the foam core for the SIPs as getting in contact with the right people posed to be a bigger challenge than we anticipated. Another issue we had about finding materials was with the plywood, it was difficult to locate exact Douglas fir plywood in ½” thickness, as many places only sold ¾” thick, after much researching and calling different companies we came across what we were looking for. We found Gorilla Glue to be a popular adhesive choice for making SIPs as it is a poly-urethane glue and is solvent free.
The first week in Pefferlaw was allocated to becoming acquainted with the facility we would be working in for the next few weeks, and also about coming together and discussing our research findings. Halfway through the day we took a trip to the site to become acquainted with the landscape and the positioning of the building. We wrapped up the site visit by moving the existing kitchen and bathroom cabinets back to the factory to be re-used in the design of the new building.

The second week began with laying the rebar structure for the concrete floor slab. The second half of the day we had a group discussion with Craig on the specifics of how the SIPs would connect to each other and to the building's frame. We explored a variety of different connection details for wall-to-wall vertical SIP connections as well as the connection between SIPs and a corner column. We settled on a simple spline connection where the foam is offset from the plywood sheets by 1" so they slide into one another. We chose to forgo a single lumber spline for the SIPs as we liked the design detail of the purlins on the interior of the space, which was sufficient for structure to the SIPs. An addition that our group suggested in coordination with the planning group was to add a Nanna-wall on both the shortened northern and southern sides of the building (bedroom and cantilevered end). We researched specific folding partition companies and came next week with information to share. Apologise
Our third week consisted of working in coordination with the planning group to design the window placements to provide cross ventilation to the building as well as an appealing design. We focussed on a sustainable window design where future owners could change the placement of the windows with as little waste of the SIPs as possible. We kept the windows on the SIP grid system so there would be minimal cuts made and the panels could be placed in different locations and reused if the future owners wanted to change the windows. While working out our placement of the Nana wall at the bedroom end of the building we discussed the structure of the beams and decided to change that side from one beam in the middle to two. We had difficulties trying to position the Nana wall to optimize the view to the outside as the beam was in the middle of the view, making this the reasoning behind the change. We worked on the exterior elevations for the SIPs to obtain the final count for the SIPs to be ordered early the following week.
Our fourth week consisted of making final minor changes to the working drawings in order to start creating the SIPs by hand. We coordinated with the planning group furthermore to decide which type of Nana window style should be used in both the living area and bedroom. It was a challenging problem, especially because we did not know if the Nana walls should open inwards or outwards, or if the windows should stay stationary, slide open or fold open like a curtain. We have also worked together with the sustainable design group to discuss shading issues in both the winter and summer (due to the amount of windows and sunlight penetrating the living room during all seasons). Later, we visited the site and did a HUGE clean up. We removed the tarp covering the foundation wall and the wood holding it down for about 2 hours. We also pumped out the dirty water that was collecting. Planning for the stairs to the basement is still in progress.

Scope of Work
The main scope of work is to ensure the SIPs are properly designed, built and the application to the building is neat and attractive. Additionally, we are working to ensure our group concept is maintained from the beginning to the end in regards to each building elevation. We wanted a dynamic design that allowed for maximum entry of natural light into the space. The elevation in the bedroom utilizes four re-used and re-cycled doors, while also allowing for the owners to access outdoor spaces in the future directly from the bedroom. Especially in the summer, it is beautiful to wake up and walk directly outside to take in the fresh air, bright sunlight, and hear the noises of their quiet surroundings.
Challenges
One of the biggest challenges was to utilize a floorplan that recently changed, and ensures our elevations positively reflected it. We also to ensure our concept was continued with the new structural and plan changes that happened. Our second challenge was testing over ten methods of increasing the force between metal supports. Every method and test had to be remembered, because in the end, we combined two of the originally tested ideas. Our third challenge this week was incorporating the existing windows (that were taken from a tear-down project) into the elevation design, while maintaining concept. It is truly a challenge to re-use materials or concepts from previous projects and seamlessly use them in a current build project.

Time Line
At this point (April 12), we have a system that allows us to construct 9 SIPs at one time. We finalized the proper distribution of glue needed to adhere the panels, and the most successful way to put the maximum amount of pressure on our panels. Our goal is to construct multiple SIPs next weekend in Pefferlaw.

Determining the details of how SIPs would be attached to different areas of the structure proved to be a labourous task. Details of how the SIPs would connect to doors, windows, corners, and tops and bottoms of the structure were a vital aspect of this design concept.

Last Tuesday (April 12), we began constructing the actual SIPs. We took a 4'x8'x3/4" sheet of plywood laid it down on top of a piece of plastic that we re-used from the wrapping of the foam. Then we spread the glue evenly across the plywood sheet.
On top of this, we placed the 5"x4'x'8' sheet of foam from plastifab. This is the insulation.
