Pavilion Development Continues

The development of the Dunham Massey Pavilions has been slowly progressing over the last two months with many different problems to overcome. Many of the original concepts have changed in scale and style whilst others have remained largely unchanged.

For Alexander Valakh and Lorena Chan the main problems have come from various material tolerances effect on their designs.

The group used the CNC router to cut plywood components for this phase of their design development. The original poppy concept that was made from cardboard and the riveted elements allowed a lot of flex. When applying the same ideas to a more durable and weather resistant material the same shapes could not be achieved. This is where 1:1 design development models come into use.To test the strength of each joint for their revised design the group decided to risk lorenas life lorena to the task. Luckily their design proved successful and despite a few oversights in fixing elements which can easily be rectified, the group can move on.

After the experimental first test in concrete casting, it was nesissary for this group to solve the issues of casting their numbers into each block. For their second attempt they tried using laser cut rubber components with a much smaller block to prevent material waste and save on weight.  Any mould is always worth considering in depth as a badly designed one will cause you a world of problems when you come to remove your cast. This box was simple but constructed well to allow easy disassembly once the cast has cured.  The finished block turned out well with the flex in the rubber numbers allowing for the expansion of the concrete as it sets. Laser cutting this material can prove time consuming and the number required may need to be outsourced due to demand on our machines from all Architecture Students. It is always worth considering outsourcing elements that need to be mass produced as if you are involved in a ‘real world’ project. Costs can often be lower and experienced companies will be able to offer you more specific advice on what you are trying to achieve at 1:1. We’ll be posting more on these project in the near future! 

Experimenting with DaVinci

Mona Lisa (1)This Mona Lisa 3D print was made from a image that was applied to Standard Primitive Box object in 3D Studio Max this had a Displaced Modifier attached, the box has then had   increased segments to make the object appear more three dimensional.  This will turn the 2D black and white Jpeg Image into a 3D meshed object that can be printed later.

Mona Lisa (3) Mona Lisa (6)Using the black and white image of Mona Lisa we have done a number of controlled tests using a raster engrave setting on the laser machine.  Paper was used initially and then card and timber this has had a number of interesting results and is proving to be very effective if an image or graphic is need for a model or surface decoration for an object.

These experiments were carried out to demonstrate yet another potential use of the CAD driven machines in our workshop and could be applied to anything from facade detailing to micro site modelling.

 

Garden Pavilions Continued – Learning Curves and Problem Solving

Development of the 6th year pavilion projects is continuing at pace down in the workshop. Test models often bring assembly issues to the surface which Alexander Valakh, Lorena Chan and Nancy Chan have been finding with their concepts. This is exactly why these models play a vital role in design development.  Here Alex has created his outer skin from laser cut polypropylene plastic sheet fixed with pop rivets. This has proved tricky and mid way through assembly it became clear that a more uniform stapled fixing would have been more effective. Lorena and Nancy have spent the last few days fixing components for this concept together. The original concept was to have a smooth curved structure forming the tunnel walkway. As the components were fixed the group found that the curve was un-uniform due to the varying strain between components. Whilst this isn’t exactly how the concept was drawn it has still proved an interesting experiment and may still be taken to the next stage.

Pavilion Project (4)The concrete cast (below) has also had some teething problems with the cast numbers not turning out as refined as the group would have liked. This process will require more thought if it is to be taken forward. The group has found that their choice of aggregate or quantity used may be to blame for the irregular casting around the number details. One thing is for sure it wont be going too far given its weight despite having a polystyrene block inside to reduce the material used!

Garden Pavilions at Dunham Massey 2013

Much like the brief set this time last year students are currently in the concept stages of designing a series of pavilions to be constructed at 1:1 at Dunahm Massey (Read our blog post here). This project was challenging for both staff and students last year and really pushed the boundaries of what the workshops can handle.

This year the project is aiming to be more refined and, with support of workshop staff, come to an effective and ‘speed-bump’ free conclusion!

Alexander Valakh (Below) is working on several sketch models to help convey his project named ‘The Shadow of War’ to tutors in the hope it will be taken to the next stage of development.

To test his theory for eventual 1:1 construction Alex had produced a plywood sketch model in identical fashion to the full size proposal on our CNC. Producing this model has allowed Alex to explore problems he may encounter whilst using this method and has already identified several areas that will need more thought. These issues are not a hindrance to the design process but feed into it and shouldn’t be seen as a waste of time. problem solving through trial and error models are often the best way of refining a design for production.

This group is also producing another concept pavilion using paper to create the sketch model. The flower-like components are created and joined using pop rivets which will eventually form a curved canopy. 

Another (!) concept from the same group involves casting concrete blocks as part of a wall sculpture. This is part of the same brief but is less interactive due to the nature of the proposed site. This was poured yesterday afternoon and is still setting so we’ll hopefully have some more pictures of how that is progressing by the end of the week.
