Introduction

This design proposal is in response to the request for Tender by the City of Munich to provide a Smoking Shelter for the Oktoberfest Beer Festival. This report specifies a design for a Smoking Shelter principally sited in Munich. The unit in question is designed to provide cover from the elements for smokers attending the Oktoberfest Beer Festival it is to be constructed on site and Hilti bolted to pre-prepared reinforced concrete foundation. All materials, design, and construction methods are to conform to the relevant EN safety methods for ergonomics, structural loading, materials and finishes.

The Oktoberfest Beer Festival is a long running festival that is held in the Bavarian heartland of Munich, annually around the latter half of September to the first weekend of October since 1810. In recent history it has gained massive media and worldwide attention and is now the world’s largest fair, attracting 6 million visitors each year. In recent years, smoking inside the Oktoberfest beer tents has been tolerated despite a Bavaria wide smoking ban indoors, in place since 2010. Most festival-goers are happy to step outside to smoke when asked and there is usually a trouble-free atmosphere; however, there is no cover or protection from the elements and a great chance smoker’s may not re-gain entry to a full capacity beer tent. With a crackdown beginning this year on smokers, event managers are seeking to remedy this situation. Therefore, event organisers have asked me to produce a solution to this problem.

Brief This year (2013) Oktoberfest event organisers are enforcing a smoking ban across all beer tents taking part in the popular beer festival. However, with no alternative rain cover, event organisers are investing in a new smoking area designed to create an inviting atmosphere and encourage smokers to go outside. The design is to provide for disabled access and take into account the anthropometric data for the 95th percentile male. My design proposal is: -

To provide a smoking shelter area catering to smokers needs. Provide cover from the elements. Produce an area for other smokers to socialize. Provide a stylish and comfortable design to encourage smokers to go outside. Produce a hygienic and eco-friendly way to dispose of cigarette butts. Create a design that blends well with the surroundings of this traditional and colourful festival. Allow for disabled access. To design in mind of the festival themes. Create a secure vandal proof structure capable of holding 3-4 users at one time. It must not have more than 3 standing walls so as not to break any smoking ban regulations. It must not be an enclosed space.

Oktoberfest Traditions Oktoberfest Advertisement Posters

Every year there is a competition held to design promotional advertisements and flyers in addition to this the winners will receive a cash prize and their design will be used on official memorabilia such as T-Shirts and mugs etc. The winners are hand-picked by event organizers and these designs from last year effectively convey the tradition, colour and vibrancy this festival embraces.

The Hofbrau Beer Tent

The Hofbrau Beer Tent is the biggest beer tent at the Oktoberfest Festival and is hosted by the Steinberg Family offering their unique 13.5% alcoholic beer. With almost 7000 festival attendees packed in here every day of the festival, maintaining order can be difficult especially when the tent is then closed to anyone else from entering. This is what makes enforcing the smoking ban problematic. Therefore creating a smoking only area separate from the main entrance would be ideal to allow smokers to re-gain entry to the tent and prevent overcrowding.

Design Development Initial Ideas With the aid of a number of sketches I was able to develop some concept ideas into viable designs, it also allowed me to keep to the theme of Oktoberfest of bright vibrant colours whilst maintaining traditions, and this structure integrates eye-catching colour with a strong durable concrete platform base.

These initial sketches allowed me to understand how the design would function and how the body would be constructed and attached to materials. This also allowed me to narrow down which materials would be suitable for this purpose, as it would need a heavy material to weigh down the shelter but, could be attached to the rotationally moulded Polypropylene side supports. CAD Development

After initial Cad development it became clear I would have to take into account 3 key factors when designing the shelter and making material choices: Cost effectiveness, Aesthetic appeal and Durability. Due to the Smoking Shelter’s main side supports being manufactured from Polypropylene there will be obvious vandalism risks therefore procedures and finishes will have to take place before final assembly and later use. I also decided that the design would be too complex to disassemble at the end of each festival day, so to avoid any injuries, damages or thefts the base will need to weigh the structure down in place. Concrete would be more than adequate in meeting these criteria as the polypropylene could be Hilti bolted to the base and securely fix design.

The timber roof would be made from a man-made panel to promote sustainability and as this would rarely been seen there would be no need for an aesthetically pleasing finish therefore the only finish needed would be weather protection treatment. This bolt fixture will be used to secure the metal beams connecting the rotationally moulded supports.

Final Design

The final design has been developed to allow for a more stable design. The supports have an added surface area at the top to disperse the dead-weight of the panel roof more evenly. The axis on the supports has been re-defined with a wider base to create a more even structure the roof has been extended to allow for adequate cover from the elements and the slant is less accentuated to prevent the structure from tipping over on one side. A smooth curve has been added to the concrete platform to permit access to wheelchairs and allow further ease of access. There is a centre table to allow users to place their drinks and free their hands whilst smoking, and below this there is a cigarette tray to dispose of cigarette ash and cigarette butts. At this point it was discovered chipboard would be the least suitable material to use for the roof, as it is almost impossible water-proof therefore it has been suggested marine plywood is to be used for the roof-cover. This material is more expensive but it will never rot and therefore the structure could be re-used in future events.

Material Choices Rotationally Moulded Polypropylene- I decided Polypropylene would be the most suitable material due to its excellent strength qualities and heat resistance as users may stub their cigarettes on the plastic and polypropylene is able to deal with this as its softening point is high at 160⠰. It also needs to hold the dead-weight of the panel roof and any impact sustained from drunken users, Polypropylene’s toughness and fatigue resistance mean that this is the most suitable choice to fit purpose. It would then be finished in colour to match the themes of the festival. The supports would be manufactured through rotational moulding, this is a cost effective process and reduces the volume of waste. Due to the rotational moulding being hollow it reduces the amount of material required therefore allowing for more units to be manufactured for a reduced price, this process also make the components lighter and easier to transport. This process is ideal for polypropylene as it is a thermoplastic and if any inaccuracies are sustained then it can be melted down and reformed reducing any wastage. Marine Plywood- This is a much more costly material than standard plywood, however it is much more beneficial in this design as it is less prone to rot and decay from wet conditions due to its durable core and face veneers and the bonding agent used to limit water intake. For this design any panels used would need to comply with British Standards Agency number BS 1088. Concrete- A concrete foundation will be used in the design to provide a platform for the user and a stable base for the side supports to be attached. This will also provide the weight to hold the structure down in windy conditions; the concrete can be formed to allow for a smooth gradient permitting access to disabled. It was considered to re-enforce the concrete with steel due to its low tensile strength however, I decided against this as the volume used would be more than efficient in holding the structure in place. Despite concrete being a harmful product to the environment, with cement production giving off harmful levels of greenhouse gasses, recycling is becoming a more and more popular option as a means of disposing of concrete due to improved environmental awareness and governmental laws so if the structure is to become redundant the platform could be recycled, meaning the structure as a whole could be recycled. The concrete used in the design would be specified to comply with European Safety number EN 206-1.

Human Scale Analysis

The Cad model has been designed on a 1:5 scale, the lowest height is 1.85m allowing the 95th percentile male to stand freely with room to manoeuvre, the width is 1.35m allowing 2 males with a shoulder width of 0.5m (95th percentile) to stand side by side with 35cm of room. The structure is therefore capable of holding a capacity of 4 users in total, including 2 wheelchairs (1 on either side) at any 1 time. It would be advised that the larger tents invest in at least 3 or 4 units to supply the user demand.

This change control form would be used by the company to officially process a component replacement or design change. If product testing were to miss any design flaws and real world usage were to highlight these problems then this form would be used to process a change on location or if required a product recall. The form is designed to clearly outline and explain the problems to the reader and effectively resolve the problem efficiently. Initially the problem is identified, the problem is then evaluated for severity and approved by the head designer/project manager this section also outlines the timescales to fix the problems, and furthermore there is a tracking record section so each problem can be recorded responsibly.

Company Policy My design company’s policy has a focus on minimal design and practice in sustainable materials; furthermore it looks towards product’s end life and disassembly looking at innovative ways of recycling and re-using materials. As well as a focus on sustainability we also strive to create quality products for our clients’ at the most affordable price.

Design Review I feel my design has satisfied the client’s requirements and needs, I feel it blends well with the colourful and unique atmosphere of this well renowned festival and encourages users to smoke outside as it provides adequate shelter from rain showers typical for this time of year. I realise some changes could be made in the design e.g. for example more consideration could be taken in the material for the roof as the marine plywood is an expensive material however, the low material cost of concrete balances this out. The benefits of this design are that it keeps the usage of the polypropylene component to a minimum.
