A Rubb Arctic adventure on the move…

This slideshow requires JavaScript.

The Rubb structure built on the ice cap in Greenland for the National Science Foundation has taken a sled ride to a different location.

As previously referenced, the Rubb BVR storage facility, known as the Summit Mobile Garage, is a 32’ x 97’ heavily insulated building designed and engineered to be moved or, more aptly, moved by sled from place to place. Due to massive amounts of drifting snow it is easier to tow the building to a new resting spot rather than remove the piles of snow.

In the pictures above, the site crew is shown towing and pivoting the building to its new temporary location. According to Marc Boutet, who spent a month in Greenland as technical advisor: “The guys told me they waited for a warm, balmy day and dragged the building to a spot less likely to get buried with drifting snow… warm and balmy means a few degrees above zero,” Marc added with a chuckle.

Actually the Rubb building was moved about 400 yards and the crew at Summit Station reported no problems with the move. “That’s because we designed and built it right,” concluded Marc.

A Rubb Arctic adventure

“What an experience!” were the first words spoken by long time Rubb USA site supervisor and current salesman Marc Boutet after spending nearly a month overseeing the erection of a Rubb BVR on the polar ice cap.

Rubb USA has completed a 32’ x 97’ BVR structure at Summit Station CH2M Polar Hill Services, in Greenland, for the National Science Foundation.

Located at 72° 36′ N latitude, and at an altitude of 10,600 feet with a mean annual air temperature of -31°, Summit Station has long challenged the physical fitness of its visitors.

In the spirit of “a picture is worth a thousand words” we can reveal a handful of recently taken photos related to the project and provide some interesting insight.

C-130: Shipping and Receiving

The Rubb building was neatly packed and delivered via a USAF C-130 equipped with skis to land on the ice cap. The interior of the plane was ‘tight quarters’ as you can see in the picture below. That is the Rubb building to the left.

Free refrigeration

Food and supplies are stored ‘undersnow’ in a dug out cavern. Due to snowfall the depth of the cavern increases significantly over time to the point where the crew will dig a new ‘refrigerator’. From the photo below you can see the crew moving supplies into the cavern.

The cladding on this building is R-35 rated Thermohall with 8” of high density insulation, after all the temperature can reach -100F! Rubb Thermohall is designed to withstand and perform in the harshest of environments.

Interior of building:

The BVR will be equipped with a generator driven lighting and heating system. The structure will support operations at Summit Station and will primarily serve as an equipment and maintenance shed. The building is set upon a foundation of wood/metal that can be best described as an ‘oversized toboggan’. Thus the structure can be moved periodically to prevent being ‘snowed over’. Rubb innovation at its best!

When asked what was most interesting experience about the Greenland project, Marc smiled and immediately said departing the site on a C-130. “The runway, actually ‘snowway’ is over three miles long and lined mostly with black flags. When you see red flags the plane must stop and turn around and try to take off again in the opposite direction. This is at nearly 11,000 ft. and the snow creates a lot of friction. After three failed attempts to lift off we stopped and the land crew attached portable ‘rockets’ to the plane to help us gain enough speed to gain altitude. I heard a couple of ‘booms’ and up in the air we went! All I could think was… what is going on? Well, I made it!”

Ask the Engineer: Occupancy Categories

Ask the Engineer is a blog segment presented by the engineering department at Rubb Building Systems. Our goal is to help Rubb customers to understand the world of structure engineering in a way that is free of jargon and easy to comprehend. We hope to educate, advise, and consult on best practices and why proper engineering is crucial to project safety and cost over the long term.

What is an “Occupancy Category”?

Occupancy category is defined as the purpose for which a building or other structure, or part thereof, is used or intended to be used. “It essentially breaks down to how many people are inside, whether it’s temporary or permanent, and the function of the building,” our engineer explained. There are four occupancy categories, each determined by the nature of the occupancy which is based on elements such as hazard to human life in the event of failure, economic impact, essentiality of the facility, and so on. The basic breakdown is as follows:

Occupancy Categories

Why do structural engineers need occupancy categories?

The purpose of occupancy categories is to calculate your design load, which is the maximum force a building must handle before being deemed unsafe. This is based on the combined weight of the building materials, occupants, and environmental effects such as snow, wind, rain, seismic activity, ice, etc.

What is an importance factor?

Importance factors are numeric values assigned to each occupancy category that will increase or decrease the design loads for snow, wind, rain, seismic activity, ice, etc. when multiplied by the base load. This calculation system is based on a minimum requirement in which the primary intent is to protect the life and safety of the public. Therefore, a higher hazard to human life will result in a higher design load, and a lower hazard to human life will result in a lower design load. Occupancy category II will always have an importance factor of 1.0, thus making the design load the same as the base load.

Who determines the occupancy category?

Occupancy category is determined by the authority having jurisdiction over the project. Although the engineer is not responsible for choosing the occupancy category, it is useful for them to know when calculating design loads for a structure.

How does occupancy category affect building costs?

Depending on the occupancy category, your price will fluctuate to account for the structural requirements and cost of materials. Higher occupancy categories will result in higher costs, and lower occupancy categories will result in lower costs. When researching and pricing out your building, it is important to compare “apples to apples”, and make sure the occupancy category is appropriate for the intended use of the building.

How does Rubb view occupancy categories?

Rubb Building Systems takes occupancy categories and the safety of those in our buildings very seriously. Unfortunately, others may not, capitalizing on technicalities in the wording of each occupancy category. Where does the line get drawn between “minor” and “major”, or “temporary” and “permanent”? “A responsible engineer determines the intended use and the customer needs, and uses their best judgment in determining occupancy category,” our engineer stressed. All of our engineers take the time and care to put the occupancy category on top of every cover sheet, so that our clients can see it up front and use it in correlation with other information. Our calculations are in accordance with the most current building codes, and all plans and drawings are documented and signed before sending them to our clients.

Fabric structures – an alternative world

Image

Rubb UK’s structural engineer Dale Robinson highlights the features and benefits of fabric structures, their versatility and the benefits they can bring to clients looking for unique building solutions…

Tensioned fabric structures are becoming a well-developed technology. Architects have had the ability to experiment and create innovative fabric solutions. They are aesthetically pleasing, sensitive to the environment, and can be very cost efficient. 

Tension structures are becoming more commonly used in modern architecture due to the pleasing aesthetic properties they hold. It is believed they are efficient structures due to their weight/ strength ratio. There are three main elements of a membrane structure; the fabric which has to be constantly in tension in order to generate stiffness in the structure, flexible elements such as ties or cables, and the rigid support member’s that are subject to compression and bending forces.

In architecture fabric structures tend to be associated with large scale projects such as the London Millenium Dome, the Water Cube in Bejing, the Kiev Stadium and Jeddah Haj terminal to name a  few. However, there is another side to fabric structures that the architecture world may be less aware of. Structures that bridge the gap between the iconic structures mentioned above and the typical cycle shelter or entrance canopy. The ordinary structures used on a daily basis in the industrial, sports and aeronautical industries. There have been numerous successful, non-iconic projects where fabric structures have been adopted as an alternative to more traditional materials for buildings such as warehouses, hangars or sports halls.

These types of structures which are most commonly akin to portal frame structures use the fabric membrane as a cladding rather than the structure itself. Therefore the natural stiffness that is generated by the curvature of the fabric is not required to stabilise the structure. This offers great advantages over traditional builds. The main advantage is having the potential for a faster installation which results in a more cost effective solution. Another advantage is the ability to specify a translucent roof which can allow natural daylight into building saving energy costs. Given the flexibility of the fabric almost any shape can be accommodated and these structures are easily deconstructed which is predominantly why they excel in the temporary and relocatable markets. More recently there has been a large requirement for this type of structure to be designed and installed as a permanent solution. This tends to be in the sports industry mainly for schools, sports clubs and training facilities for professional sports teams. For a permanent solution additions can be made to the structure to include insulation, heating and ventilation to meet the necessary environmental regulations and more importantly to comply with Part L of the Building Regulations. Other ancillaries can be incorporated such as gutters, windows and doors along with any other additional requirements to provide sufficient amenities to the end user.

A fabric clad building solution is one of the most versatile and innovative solutions to modern day building problems. Although these structures tend to take the geometric stance of an industrial shape structure the shaping possibilities are limitless. The specific market and cost restrictions generally dictate this type of structure albeit we have seen exceptions in sports training facilities where alternative shapes tend to be introduced.

If a project operating on a tight timescale and requires a reliable, robust and cost effective solution, fabric covered buildings should be considered. They are designed suitably, as any other building, for the relevant environmental loading and to comply with Building Regulations. There are a variety of fabric colours available, that come with the necessary information on fire resistance and thermal properties to aid the designer. These structures can be partly clad in fabric along with alternative materials to form a unique hybrid solution which enables the architect to easily incorporate their own ethos into the final solution. Not forgetting this type of structure is sensitive to the environment and most fabric is recyclable which in turn makes this option sustainably viable.
