6 months ago, we hired a custom furniture designer-manufacturer to create hybrid custom seating and storage for our tiny green office-classroom, designed after a boutique hotel in our company's namesake city Vernazza, a fishing village on the Italian Riviera. A few months ago, the CEO of the custom furniture design firm said that the first prototype failed structurally. The MDF no-VOC pressed wood sagged when one 180-lb person sat on only 1 of 2 seats. His team had designed, not engineered. Designer is claiming the need to switch from MDF to solid hard wood ... at 3 times the cost. Since then, his team has redesigned per the insights, feedback and questions from 11 Upwork bidders. But, he can't/won't do Finite Element Analysis (FEA) or confirm that the design meets/exceeds international ISO or BIFMA office chair & cabinet standards. See his answers to your questions below. He is also claiming that he can't affordably cut and glue the Wilsonart Tan Echo laminate on his bench design (materials & labor in Mexico, to be delivered to Houston, TX). We need help finding finished turnkey solution. We'd like an Upwork expert industrial engineer / furniture designer / hands-on furniture craftsman-building-manufacturer to review/critique/improve/optimize the design for durability, simple elegance, lightest weight, cost, and ease of fabrication. Specifically, it has been difficult to find a company to cut the wood & laminate with a CNC router. Laminate seems to double the project cost. Need strong bench to support full lateral filing cabinet storage (calculate cabinet full of dense copier paper) + two 350-lb seated guests. We need an industrial design engineer to re-engineer and fix the manufacturer's design, using the existing (donated Wilsonart Tan Echo laminate) materials and design. The intent of the six two-seater benches: - surpass internationally accepted design & engineering standards for office seating (chairs) and lateral filing cabinets (storage) re: ergonomics, fire safety, ruggedness, impact on light in space, form (texture, comfort, intrigue, etc.) - to be used daily by up to six sustainable real estate consultants for hidden, secure (lockable) lateral filing & other storage - to be used 3-6 times monthly as a classroom seating for 2 to 8-hour ECO [BOOT CAMP], GREEN [BOOT CAMP] and SOLAR [BOOT CAMP] courses for real estate executives and heads of households - tiny green office-classroom is 14' wide x 28' long - appeal to well-traveled real estate executives, but speak elegant (sophisticated) simplicity (frugality) - lockable rollers suitable for linoleum floors - retractable (hidden) seat backs that may feature Hawaiian seat back cushions since we've been doing ENERGY STAR benchmarking and certification of commercial buildings in Hawaii - large single bench seat cushion (not 2 seat cushions as shown in materials takeoff) seat cushion: 23.1" - wide x 20.0" - deep x 1.88" thick seat back: 16.3" wide x 13.9" high x 1.88" - thick (?) Here are the manufacturer's answers to Upwork bidders' questions: 1. You’d said "MDF just doesn’t hold because it’s meant for aesthetic not for actual weight support.” So, how are we back to MDF? ANSWER: The top can be plywood and the rest can be MDF because it is only for aesthetic. If you really want to use laminate, then MDF has to be used because wood expands or contracts and laminate will come undone over time. 2. Could you please send me a PDF of the AutoCAD, and also send the AutoCAD with materials takeoff and descriptions, so that an industrial engineer can perform the ANSWER: See 3 new renders 3. For the structure I think have 4 points need to revise: a) the bottom should add support. ANSWER: Weight is distributed by PTR underbelly. b) the bottom of seat need to reinforce structure. ANSWER: Seat is made of 1” plywood and weight is supported on all 4 corners evenly. c) the structure of the back is unreasonable. ANSWER: Internal structure made of metal d) the door of the lateral filing cabinet also need to amend. ANSWER: none. ANSWER: For the material I suggest using sustainably grown & harvested plywood (FSC not SFI certified), because the structure stability is stronger than MDF & the cost is cheaper than solid wood. 4. First of all I see no internal support .. which would be blocking , gussets, or support ribs.. this would improve 10 times.. I can do this project this week .. and have it by Friday. I have reviewed the takeoff drawing attachment. What plywood thickness was specified? I can redesign and or improve this concept with some modifications. ANSWER: Design now has internal frame of 1” thick PTR welded together. It provides a frame and equal weight distribution. We also recommend the cabinet top be thicker (1”) & plywood. In any case, we can provide mid level support for each person by inserting cross bar ptr.

For many years we have used my excel sheet to calculate prices on out steel buildings, now we want to make that excel sheet into a price configurator and put it on our website. The configurator should be able to: -Calculate price on the building based on the excel sheet - There shall be possible to add accesories to the building, doors, windows, gates etc. - Graphical animate the building based on the user input - The user shall be able to create an account, and there the user can see the projects he has calculatet earlier. - We want to be able to change prices in the backend. - The program shall be able to produce dfx files of the building. - User shall be able to save their project/building. So that they later can login and modify this project. - Administrator shall be able to open a project that is made by the user and modify it. - User shall be able to print the project, with drawings and prices. - Program shall animate the building based on the input of the user. 2d is most important, but 3d would also be nice. - Drag and drop placement of windows, doors and gates. - Program does not need to work on mobile devices. We have made 2 prototypez of the program. The program is made with unity. What is missing in the programs is: - more detailed graphics - Backend - DFX files - Has made to many compromises in the prototype. Please contact us for link to the prototype. For inspiration we have looked at : http://www.hts-industrial.com/configurator/ http://www.astron.biz/en/building-configurator/ http://buildingconfigurator.histruct.com/Component3D/?componentPrototypeName=Configurator_AgriculturalBuilding.fcc - This very advanced. It is not necessary for us to have it this advanced, still it would be nice.

I am seeking a USA-based licensed structural engineer that knows the USA, Florida code to work on a house made of shipping containers. My name is Moshe, the owner of http://www.cargocontainerhome101.com , The only social media network created to assimilate and organize information, and to then inform and instruct interested parties in the construction of a shipping container home—a new and growing approach many people are using to meet their housing needs In Florida and around the world. I am seeking an engineer that sees the value of this project and have a passion for the shipping container home concept. This social media network is envisaged to bring shipping container home-builders together to share their building experiences thru images, videos, and member chats and by these means to recommend appropriate engineers, architects, share other members’ solutions and solve the common problems that they experience. The network is intended to be both an instructional source and an advocate of this exciting global evolution. As I’ve discovered, and you may be aware, shipping container home-building is an innovative solution to the high cost of traditional home building that is becoming a new, fast growing trend embraced by thousands of people in Florida and around the world who want to live in a dwelling that is an economic and environmentally sustainable home. As part of my network’s offerings to its members, I intend to construct, from the ground up, a unique house made of reclaimed shipping containers. I will be documenting this project with videos demonstrating each step of the construction of a sustainable shipping container home. Those videos will be viewed by members in Florida around the world. I am endeavoring to be LEED certified and to be featured on its website (http://leed.usgbc.org) as the first sustainable shipping container home in Florida. I am currently seeking a USA-based structural engineer and an architect that will be prominently identified during the video presentations on the social media network. Please contact me if you wish to participate in this project. Log in to see more info about the project. Thank you. Moshe

We are building a house out of shipping containers. As major walls are cut out we need a structural engineer to design where support beams and posts have to be added. Also we will use a green roof with a max weight of 290 pounds per sqft. As the container roofs are not meant to hold structural weight they need to be supported somehow. The foundation needs also calculated and defined based on the load. The attached file is an Archicad V 18 file, I prefer freelancers who can work with this. However work can also be done in autocad as 2D. Detailed drawings will need to be provided for attached beams, weldings, foundation etc. I assume that most bidders will have no US permit. I have a local engineer who can sign the plans, but needs a paper with description and calculations to verify it was done correctly. Files are at this location: https://drive.google.com/folderview?id=0BwoGD4TukNxrQzd0UVA3M3JOSFE&usp=sharing

Howdy, I build shipping container homes in Houston, TX. I need a structural engineer to design a foundation and balcony for a new home. Engineers in the US charge me $75 an hour to review and approve drawings. I have done a vast majority myself up to this point, but I am becoming busier and busier. I need a structural engineer to design floor joists, attachment methods, read soil reports and design a foundation to suite, and more. You will need to be able to show all of the calculations for your work as it needs to be reviewed by an engineer in the US. Texas law requires a registered US engineer to approve the projects and take liability for the project. The first project that I have is for a 5-story home. I have the basic designs and using shipping containers makes the plan very modular. I want to start pay at a low rate and increase once you complete a few tasks acceptable. Price is very negotiable and will be based entirely on quality. If I have to continually review and amend poor work I am not willing to pay much. If you can handle the task outright I am willing to pay much, much more.

We have an existing pool design and need now detailed plans for permit and construction. US permit is preferred, but if you do not have any, we have an engineer which can verify and sign your work. We will build the pool ourselves, so we need 100 % accurate plans including all piping, pumps, rebars, etc. Please only bid if you did such jobs before and can proof it. This is not a simple project and needs somebody experienced. The attached files are the design renderings. We have cad files for the house, but none for the pool. The design is not 100 % set in stone, so feel free to offer improvements. Original house was designed using Archicad, so this is the preferred platform. However guest house was design in Autocad. So either this or Revit will be ok. The images are at the following link: https://drive.google.com/file/d/0BwoGD4TukNxrazJ6Wk1xNFFITVU/view?usp=sharing
