Designing Global Cooperatives – One Community Weekly Progress Update #437

This week the core team continued working on the “Earthbag Construction Footers, Foundation, and Flooring” live page as a part of designing global cooperatives. The web editor in our team finished editing the technical part of the One Community´s Earthbag Dome Footer Foundation and Flooring.

He then began the final comprehensive read he does before submitting it to our final grammar, spelling, and clarity reviewer. In doing so he spotted some inconsistencies around the different earth dome related pages, so we need to address those first. The pictures below share some of this work and what he found.

Jose Luis Flores (Mechanical Engineer) completed his 55th week helping and finishing the Net-zero Bathroom component of the Earthbag Village.

This week Jose Luis continued updating the exterior roof rendering of the net-zero bathroom. The updates included resizing the cross sectional dimensions of the tangential support beams attached to the radial beams.

The previous design utilized 4 by 4 wooden beams, but was updated to use 2 by 2 wooden beams. This decision was made because of the reduced cross section of the radial beams, which in turn was caused by the reduction of roof panel weight.

The difference in density between galvanized steel (7.14 g/cm3) and galvalume (3.75g/cm3) had not been previously taken into account. The advantage of the weight reduction is the reduction in needed support for the roof panels and the structure itself.

The amount of lumber needed is also consequently reduced by the weight savings. The references needed for the positioning of the components in the rendering had to be heavily revamped due to these changes as well. The pictures below show some of this work.

Nicholas K. de León (Project Management Adviser) completed his 8th week helping with review of Highest Good Housing research and related tasks. This week Nicholas focused on direct edits, smoothing out the research and fixing grammatical/spelling mistakes to improve readability.

It seems that many of the documents are simultaneously getting closer to being finished, while additions (apart from changes or edits) take the docs back a couple of steps. This is completely expected, only to be noted because it means that some tracking and backtracking is needed on Nicholas’ and other editors’ part.

The phases these documents go through are less distinct, naturally, with this current “phase” being a mixture of many different ones: writing, editing, supplementing, and in some cases reordering and restructuring.

After taking the time to re-read most of the six documents, Nicholas felt that the vast majority of the apparent minor issues had been solved, with the inability to find a lot of errors being a welcome sign.

Thus, this week will be spent returning to more major issues like suggestions for clarification, and making edits, where needed, to large formatting problems. Pictures below show some of this work-in-progress.

The Compression Team consisting of Dominick Banuelos (Civil Engineering Intern), Jarot Tamba (Civil Engineering Intern), John Paul D. Matining (Civil Engineer Intern), and Marcus Nguyen (Civil Engineering Intern) completed their 4th week in helping with the Aircrete and earthbag compression testing.

This week they worked together to create a standard test cylinder for each of the 3 mixes: aircrete, compressed earth, and concrete. After a few weeks testing and experimenting, the group thinks they have their concrete and stabilized earth portions of the project mostly figured out.

These mixes were created to replicate what the final mix will be in terms of how much of each ingredient is added. The team also worked to make a video of how to do each mix such as measuring out ingredients, pouring ingredients together and mixing them, pouring the mixes into the cylinders, etc.

One of the biggest issues that the group have been trying to figure out is in regards to the aircrete. The issue with the aircrete is that once it has been poured into the cylinder and it sits there for a while, the mix shrinks down either a quarter of the way down or half way down.

Further research was done to understand why this was happening and what could be a solution. The group believes that there is something amiss about the measurements or the mixing process and will continue testing new approaches next week.

Chris Weilacker (Software Engineer) completed his 34th week working on the Highest Good Network software.

Chris worked on testing the auto-assignment functionality a second time, as well as adding text to describe the timing of the badge auto-assignment each week and demoed the project for a video on the badge functionality and double checked that volunteers can not change their count and/or delete the badges from the report button.

Chris also added a space after the description text on the report. Although the badge testing did not work as perfectly as expected the error was in the fact that someone else was running the backend locally for the dev environment which double-counted the badge count increases on certain badges, and on the new category badges.

For the economics category which Chris’s dev-admin account did not earn last week due to him not inserting enough hours. It got two badges as the code added in the badges.

It worked as expected on upgrading the badges from 100 to 200 due to that code replacing badges instead of adding badges, so, all-in-all, it worked as expected and this would not be an issue on the beta or production site as there is but one server running. Pictures below are related to this work.
